GATE_For_PM Account Config
Inspiration
I'm a Sr. software developer. In the summer of 2015 I watched a PBS TV show called "Rise of the Hackers", in which it talked about the vulnerability of the Internet and said traditional password is a weak link in cyber security. That inspired me to do something about it and fix this problem, so I came up with a solution called GATE : Graphic Access Tabular Entry.
What it does
GATE is an interception-resistant user authentication system, which means even if someone intercepts/sees you when you log in [ assume he sees/records every detail of your authentication ], he still won't know what your password is.
Based on user password choice, server renders password entry buttons/tokens on a screen, rendering multiple characters per button. When button selection is made by a user there is no way for an observer to know the actual password due to the multiple characters per button. This makes GATE an interception-resistant authentication system which increases passcode strength exponentially.
Each subsequent rendering of buttons by the server will be unique, based on the GATE algorithm, ensuring button selection cannot simply be repeated based on button location in order to infiltrate an account. Due to the rendering process required in order to present password buttons to a user, a server has to already know the password of the user in order to render an appropriate array of buttons. Therefore bogus or malicious servers will not be able to render an appropriate array of buttons to a user, which allows the user to recognize whether or not the screen he is looking at is being controlled by the appropriate body. In traditional password system, server authenticates user, yet with GATE, user also authenticates server, therefore defeat phishing by design.
GATE can use short and easy to remember passcodes to defeat peeking, wiretapping, keylogging, phishing and dictionary attack without the restrictions of lowercase, uppercase, numbers & special characters !
How I built it
I used Java Swing to build it.
Challenges I ran into
Not much.
Accomplishments that I'm proud of
I've received 2 US patents, one for GATE authentication [ user login ], another one for GATE encryption [ massage/data encryption ], and I've also applied for PCT international patents in 50 nations.
In the past few years it has won 6 international cyber security awards.
What I learned
To think like hackers in order to defeat them.

Unity of purpose in the Future Internet
Inspiration
Common vision to enable, protect and conserve life and the operating climate in entrusted ways
The Internet's Influences on us (common people)
The Internet on being available provides us with a continuity to interface with people, specifically skilled or interested elements, businesses, organizations, systems, platforms, in socially accountable ways or less lest said ways.
The “open-nature of the influences on us as common people” is not deterministic.
Activation of Influences on us (Operating Climate interested people)
The Internet to most of us needs to step next into being open-but-operating-climate-centric where being open-nature is as described above.
What is the Operating Climate (OC)?
The term OC refers to the climate due to the Natural systems interface (NSI) present in or near regions and our life interests to involve ourselves in many sense & respond cycles..
What is the Natural systems interface?
NSO refers to the topography, rock and soil texture, forest cover, river system proximity, ground water table sufficiency, sunlight, shade, winds and rainfall patterns.
What it does
Being operating-climate-centric means
Adding an Operating Climate Centre (OCC) in addition to the Network and Sharing Centre etc we find on our systems
Having Behaviour Trending reported by the OCC such as
Service or System application usage while being online
Via Internet application usage while being online
Interactive application usage while being online
File and storage usage while being online
Time of usage while being online
Situ of usage while being online (work from office, work from home, work from other sites)
Having SMART Intervention elements to understand and mitigate risks to any Natural Systems Interface and Inter-connected climate like “caused or emergent”
Pollution levels
Resource depletion levels
Economic downturn levels
Risk to right to information levels
Having a function of “interaction pattern-evaluation & environmental-impact assessment” to report any “sense & respond enabler like readiness, repair, restoration & transformation for climate change mitigation”
4.a The Interaction patterns could involve
Connectivity
System re-login or restart
Search engine utilization
Group communication
Conscious Leaf enabled interaction
Goodwill at work enabled interaction
Fast Tracks enabled interaction
4.b Environmental impact assessment could include Digitally-enabled-assessment of
Env-availability
Env-kinetics
Env-dynamics
Env-uptime-efficacy
Env-adverseness like reporting of auxiliary alerts, hotspot alerts, weak-spot alerts
Background to alerts etc
Auxiliary alerts could involve alerts about Visibility levels, Pollution levels, Acid rain levels, Solar radiation or Thermal levels
Hotspot alerts could involve alerts about incidence afflicted g-sites, where g-sites are Geographical sites, Internet sites or Access sites. It is expected that today’s sites could become Grid connected sites or remain what they are today for the edition of the Internet used.
Weak-spot alerts could mean alerts about chronologically slowing down g-sites or Earth Facts afflicted g-sites, where g-sites are Grid connected to report anomalies or affliction
Steering ahead
We could start by editioning the Internet, from what it is today to an edition called the Futuristic Internet
This means that as users we could register into a Futuristic Internet platform, where we need to register details about
A. The Behaviour we need to be surveyed
B. Our interest to protect the NSI and inter-connected climate
C. Our interest to sense & respond to environmental impact or operating climate change

Inspiration
As part of the billions that have been impacted by the coronavirus pandemic, we wanted to make this website and interactive map to create a positive impact on our own community!
What it does
While these resources are available online, we wanted to combine all of them onto a single page. Our website is made from scratch but our main spotlight if our interactive map because we believe that it provides all sorts of resources depending what a Houstonian would need.
How I built it
In order to make both of the website and the interactive map, we worked in teams and checked each other's work at the end. Two of us worked through Leaflet Libraries making the interactive map with the use of Javascript while the other 2 used HTML to make the website.
Challenges I ran into
We definitely all agree that our time constraint was a challenge, a lot of us had many ideas to input but because of time we focused on the most important aspects.
Accomplishments that I'm proud of
We're all really proud of making a functional and user-friendly space! We think this would be an accurate page for people in the Houston area to refer too for COVID Resources.
What I learned
For us, it was definitely a large project so we really questioned whether we could finish everything on time. For me, it was having a refresher on HTML. For others, it was their first time even looking at a coded website. It was just an overall fun experience and a product that I didn't think we could have achieved in the time constraints.
What's next for COVID-19 Relief Website with Interactive Map
We hope that our COVID-19 Relief Website keeps growing! The team would have loved to see the map expand to the regional or state level for many other people. We would've loved to translate the website into other languages because we know how diverse Houston is and have provided more information for people who are undocumented. We would have also liked to put a search bar to make it easier to find places with everyone's zip code.

Disaster Help Index
The one-stop website to see world disasters and events and learn how you can best help
Inspiration
As 2020 started off with wildfires in Australia, and February moved to a terrible locust outbreak in Africa, followed by millions placed into quarantine in Italy due to the Covid-19 outbreak, 2020 has been rough.
We decided that there were so many events going on in 2020, it was hard to keep track of what was happening where, and knowing how you could help. That's why we made Disaster Help Index or DHI.
In addition to struggling to keep track of disasters in the world, many are not getting the support they need. Rather than sending what you think may help people in disaster areas, they are able to submit their own requests that you can fulfill.
What it does
DHI displays a map of the world, showing you a large collection of all the current disasters with a legend to categorize which one each falls under. You can also click on a disaster to get more information about it, including some stats and a description.
In addition to displaying stats and a description for each disaster, DHI shows you various categories and items that locals in the error have requested that you can do to help. Some of these may be items you could pay for for them or something simple like writing to your congressional representative to help enact support from the government.
Our website also has functionality built in to allow people to self-report disasters and add requests to a disaster. All of these features also use your IP address to verify you live in the disaster area. This protects our database from being flooded with false data and allows only locals and those directly affected to submit a request for help.
How we built it
We chose to separate our project into a frontend and backend, both hosted separately. The backend acts as an API that our frontend can query.
The frontend is a React app running on Vercel (
e-hacks2020.vercel.app
). It uses the Google Maps API to automatically turn the location into geolocation coordinates that can be displayed on the map.
The backend is a Python Flask app running on a Ubuntu server configured with an Nginx proxy. It uses Firebase Realtime Database to store the disasters and requests. It uses
ipapi.co
to find and verify IP addresses.
Challenges we ran into
On the backend said, Nginx was passing all IP addresses to the Flask server as localhost, which makes sense as it is a proxy. This was solved by adding headers to the proxy_pass and forwarding them to the Flask app.
On the frontend side, we had quite a few issues in both rendering maps properly as well as sending all the data to the backend. Both of these issues were fixed with teamwork, perseverance, and a lot of reading through error logs.
Accomplishments that we're proud of
We are incredibly happy to have our entire project finished and fully functional with a demo anyone could use.
Most impressively of all, two of our four teammates were complete beginners to programming, so getting them up and running learning how to use GitHub, VSCode, and Python/React was a struggle. In the end, they were able to contribute to our project heavily and made incredible progress!
What we learned
Two people on our team were completely new to programming so they learned a lot about Python and React and all the systems tying our code together.
What's next for Disaster Help Index
We hope to grow our platform to the point where real people are using it. We don't need to change any code because we have it developed in an easily scalable way. This ensures that our project could take off overnight without requiring any intervention from us.

When disasters hit, many experience a loss of shelter, transportation, food, water, energy, and much more. Often, those hit by a disaster cannot receive aid from the government or other large national organizations until long after they need it. Our inspiration came from hearing one of our members describe an instance where her family relied on her neighborhood for relief during Hurricane Harvey.
What it does
By mimicking communities in real life, we created an online community forum, where we aim to gather members of a community to volunteer to help others in need. In the future, the forum open to registered volunteers of certain organizations (school clubs, churches, etc) to further distribute and circulate volunteer opportunities. Centralizing volunteer opportunities, especially during disaster strikes, reduces confusion and increases incentive.

Inspiration
On the first day with my teammates, we all weren't really sure what to do. None of us had done something like this before, so we were kinda lost. Eventually, we found out that we all lived in Texas, so we thought that it'd be a good idea to do something involving the state of Texas. We eventually decided that it'd be creative and helpful to make people aware of the possible threat, probability, and history of tornadoes in their area. We started searching for Texas Tornado data, and I began the front end coding.
What it does
We
initially
planned for the website to be able to do the following:
Find user location & date
Calculate using the location and date to find the probability of a Tornado
Have a map with a location and allow the user to search for other areas and percentages
Show graphs with the history of tornadoes in the area using Java
However, we ran into a few problems. Since we weren't all that experienced, we decided that we'd allow the user to select their county and month, and do a few quick equations to solve the probability. Using PHP, I made a little form that allows the user to select the 54 most popular regions in Texas and the 12 months. Using this data, my teammates and I then planned to use the large area you see to display the history, probability, and graphs... but, we had errors with the data, and it pretty much messed up our whole program, so no data gets displayed.
How I built it
I used PHP and CSS to code the website. Michelle and Claire used Java and C to calculate the data & graphs. Andrew used C# to try and find the location but then used Python to calculate the location & date for a result.
Challenges I ran into
As you can tell, we were not able to get the data in enough time, and it would've taken another 3 hours to code the statements to display data based on the code. We just didn't have enough time.
Accomplishments that I'm proud of
Coding PHP! I've never done that before! Also, being able to get such a large amount of information, like the location and type of tornadoes in the area using Java is incredible! I'm super proud that we did that. I personally believe that the best part of the entire project was the information compiled by Andrew. Take a look at the video to see it!
What I learned
Hackathons are fun. That's it.

Inspiration
Many businesses are having trouble ensuring the safety of their customers by preventing people who refuse to wear masks from being near their store. MaskCam solves that problem, by alerting the owners and nearby users of the app to the danger. Wearing a mask is the #1 easiest thing we can all do to help save lives during the pandemic, but some people simply don't do it. Alerting people nearby of these dangers will help reduce the damage dealt by anti-maskers.
What it does
MaskCam leverages the Google Cloud Video Intelligence API to label videos recorded by an Arlo security camera. If it finds a mask in the video, it alerts the camera owner, but also anyone who has the app. Using the Radar.io API, only nearby users are alerted, and told they are in danger of being infected.

I used Flask and GAE to write the backend, and used the Arlo API to pull videos from the camera. Determining whether there was a mask in the video was done by Google Cloud Vide Intelligence. For the mobile app, I wrote it in Swift and communicated with it to the server and using the Radar.io API for distance information. I used Bulma.css and Jinja to render the templates for the website.
Challenges I ran into
I had a lot of difficulty getting the Radar.io SDK to work in Swift, but eventually got it to work. Also, the Cloud Intelligence API had some difficulty recognizing surgical masks whereas homemade masks were more recognizable for it.
Accomplishments that I'm proud of
I am proud that I was able to put together such a big project as a solo hacker. This was my first time attempting something so big, and my first time using cloud Video Intelligence and Radar.io. I'm glad that I was able to get it to a working and presentable state.
What I learned
I learned a lot about google cloud APIs, the entire Radar.io API, and more Swift and app development.
What's next for Mask Detector
More camera APIs (e.g. Nest) could be added for more accessibility, but for now it only works with Arlo cameras.
NOTE: I did submit this project to multiple hackathons, but I was very careful to only work on it after all the hackathons had started and before the first submission deadline.

Inspiration:
We were inspired by the tragic events of Hurricane Harvey and the destruction it caused.
Struggles:
We were having difficulty finding a problem and a good solution for the entirety of the first day but we finally got the ball rolling on the second day during the afternoon. Our biggest problem was shutting each other's ideas down
What we learned:
We learned that hurricane Harvey caused 500 thousand cars to become flooded, which causes hundreds of thousands of dollars, if not millions in damage, and we also learned about Arduino boards.
How we built:
we drew a few diagrams and used Cad to make a 3d model

We simply thought about it as we discussed and pitched ideas. We didn't want to "generically" base our project on Covid-19 because we thought that other groups were going to do a project about COVID-19.
It's a website with a homepage and two links which go to two other pages that describe Hurricane Relief and Hurricane Preparation respectively
We used Notepad and HTML
We ran into one specific challenge where we couldn't get the homepage links to take us to the correct pages
I'm proud of how our team worked together to build this website even when we didn't have much experience with code altogether.
I learned how to code with HTML
I think hurricane relief and preparation could've expanded to disaster relief and preparation with the capability to directly help others with interactive surveys if monitored by the government.

What it does
There are two people using it, the helpers and the helped. There are commonalities and differences between these two.
Both can choose to use their location through geolocation, or enter their latitude and longitude manually. They both can enter their names and their phone numbers, and both can enter a short message. Once they submit their information, a marker pops up with their name and their role on a google map. If someone clicks on their marker, their information shows up.
The people requesting assistance specifies how many people should come for help.
The people giving assistance to others can select a marker, and it will show their distance. If they choose to help that individual, a line will show up and connect their marker with the assisted individual for all to see. If another helper comes online that is closer to the assisted than the current helper, the newcomer can click on the previous helper, get his phone number, and contact with him and the helped.
This provides a simple and useful way for people to give and receive assistance when necessary.
How we built it
We built this using the ASP.NET web api framework, so if needed, anyone can use our app. The backend is coded in c# and the frontend is (obviously) coded in Javascript and jQuery.
Challenges we ran into
We first planned on using Node.js for our backend, but we found out that node.js doesn't allow POST and anonymous requests, and setting up a Node.js server on Azure was too tedious and difficult. Instead, we packed everything up and decided at the last minute to move to .NET, which both saved us and cost us a lot of time.
Accomplishments that we're proud of
We're proud of the outcome of our project. When we first started, we didn't think we would get much done, and we didn't have many ideas. I don't think any of us could have predicted this outcome.
However, the outcome is definitely not just the outcome, but what we learned getting here. Many of us didn't have much knowledge on requests, and most of us only heard of Node.js once or twice. But after completing this project, we now have a solid understanding of these topics that we couldn't have learned otherwise.
What we learned
As said before, we learned the different types of HTTP requests through the Javascript's built-in XMLHttpRequest feature. After moving to .NET, we also used the jQuery .post and getJSON features.
We also learned how to host a server using Node.js, which many of us did not know how to do before now.
What's next for eHelpers
For the website, we plan on making this website easier to use for people with disabilities. We will also be increasing the security by having users register an account, make the backend bulletproof, as well as fix any exploitable weaknesses.
The main focus, however, is to make a phone application. A web application is too hard and inconvenient to use, while a phone app makes it much easier, and opens up many opportunities and tools, such as a GPS.
We also plan on engaging hospitals and stores/restaurants such that people can view nearby hospitals and stores and gather information about these buildings. This information includes average wait times, availability, infectious patients, and communication between the user and the store/hospital.
We will also be expanding our website for additional applications past disaster relief, such as helping in outdoor sports rescues.

We wanted to have a website that could help people get all the information they need during this pandemic.
What it does
We have multiple tabs inside of the website. Some of them have maps where you can find the closest food bank or testing site. Our main feature is the small businesses tab. Businesses that have been affected by COVID can fill out the form and it automatically transfers it to a spreadsheet where the public can view. They can then support the businesses by purchasing from them. We also have a lot of information on the coronavirus and donation pages.
How I built it
We used google sites.
Challenges I ran into
It was kind of difficult to embed everything and also to make sure everything works.

What is Locality?
Locality provides reliable sources of local news in order to combat misinformation. The first step is to enter your City, and just like that, your job is done. From there, we aggregate local news stations around you, and display them on a beautiful grid.
Locality uses an API that aggregates local news stations, and neatly arranges them on a webpage.
How Was Locality Built?
We built Locality using React and a hint of Python-Flask for the backend. As for the news, we fetch search results under the news category via the Zenserp API.

One of our group member has had suicidal thoughts, but luckily didn't commit suicide in the end. This inspires us to be able to find a way to detect depression in hopes that others can get help quickly if they have a similar condition.
What it does
It helps determine whether one shows symptoms of depression, especially for children and teens. We hope this can be a useful part of disaster relief because we think that mental health is really important and those with mental health problems should get the help needed.
How we built it
We built it using scratch by inputting codes and importing pictures made by our members.
Challenges we ran into
Since everyone was online at different times, communication was definitely a big issue we faced.
Accomplishments that we're proud of
We were able to finish this project in less than two days .

This application will help users/patients to connect with their doctors and getting immediate and remote assistance for their health. This may also act as a health tracker.
The application aims to solve the problem of doctors’ availability at this time of crisis. As most of
the countries are going through lockdown at the moment, and doctors are working on finding a
cure for COVID-19, it became very difficult for patients to get a checkup even if they have
common flu.
What it does
This application will help users/patients to connect with their doctors and getting
immediate and remote assistance for their health. This may also act as a health tracker. The application aims to solve the problem of doctors’ availability at this time of crisis. As most of
the countries are going through lockdown at the moment, and doctors are working on finding a
cure for COVID-19, it became very difficult for patients to get a checkup even if they have
common flu.
This application will help solve this problem, by providing a platform for patients and doctors to
interact and share details and prescriptions so that the patient can get assistance anytime.
This application will not only be useful at such critical times but can also act as a health
monitoring device for patients who require regular monitoring and checkup.
How we built it
Steps performed by the patient:
● The patient register himself as a patient on the Registration tab
● After registration, he can upload his health care data in the form of excel files, pdf, docx,
or images. This data can be recorded any smart device that the patient may have, or can
be compiled by the patient or any relative.
● Once the patient uploads the data, he will get a unique hash that points to his data on
the IPFS blockchain. The data is encrypted using AES encryption so that it is not
understandable by anyone.
● The patient can then share this unique hash with his doctor (who is also registered on
this platform).
● The doctor can then view this data and send the prescription accordingly.
● The doctors are incentivized using the token mechanism (HealthToken) which we have
introduced.
Steps performed by the doctor:
● The doctor register himself as a doctor with his fee (fee to be paid by the patients to get
diagnosed and get a prescription).
● After registration, he can view the files which his patients have sent him and then he can
diagnose and send the prescriptions accordingly.
● After the doctor sends the prescription, he will receive his fee in HealthToken.
Incentive mechanism:
● We introduced native ERC20 tokens, named HealthToken.
● On first registration, users (both patient and doctor) may receive 1000 free tokens
(owner can send it to each user only once) so that they can use the platform (this may
act as ICO)
● When the user sends his data to the doctor, the doctor’s fee is automatically deducted
from his account and is stored securely in the Smart Contract.
● The stored fee is only released and sent to the doctor only when he sends the
prescription to the patient.
Challenges we ran into
We overall faced 3 major challenges:
1) Storing web3 and contract instances in local storage because of their cyclic redundancies.
Found a workaround by removing cyclic objects.
2) Deploying smart contracts on the Matic Network. Solved after discussing the same with the
Matic Team.
3) CORS error with IPFS storage. Found a solution on google.
Accomplishments that we're proud of
This application will help solve this problem, by providing a platform for patients and doctors to
interact and share details and prescriptions so that the patient can get assistance anytime.
This application will not only be useful at such critical times but can also act as a health
monitoring device for patients who require regular monitoring and checkup
What we learned
Use of :
PFS:
○ IPFS is a data storing platform and is used to store the patient’s data.
○ Storing patient’s data would be very costly and not very efficient which made us
choose IPFS for data storage.
○ The IPFS hashes are generated according to the content of the files so it is
practically impossible for any random user to find the unique hash.
○ By any chance, if any hacker finds out the file hash and tries to steal the data
from IPFS, then he will have to decrypt the AES encrypted file which is another
practically impossible task.
○ The patient can share his file hashes with the doctor. To view those files, the
doctor will have to download files using our platform only so as to decrypt it.
Hence allowing only legit users to access the sensitive data.
● Truffle:
○ Solidity dApp development framework.
● Metamask:
○ Browser extension that acts as a bridge to connect ethereum network with
browser.
● Matic:
○ It is a Layer 2 scaling solution that achieves scale by utilizing sidechains for
off-chain computation.
○ It is used to remove the gas price for every transaction and to make the
transactions faster and efficient.
○ Because of Matic Network, the application doesn’t have any extract cost at the
moment (0 gas for every transaction).

A recent Federal Emergency Management Agency (FEMA) survey found that nearly 60 percent of American adults have not practiced what to do in a disaster by participating in a disaster drill or preparedness exercise at work, school, or home in the past year. Further, only 39 percent of respondents have developed an emergency plan and discussed it with their household. This is despite the fact that 80 percent of Americans live in counties that have been hit with a weather-related disaster since 2007, as reported by the Washington Post. With nearly** 61% of _ Americans having not prepared a emergency plan in case of a widespread emergency in their local area and **no basic technologies present to sufficiently provide information to local authorities to provide help to one another, I felt the need to develop this app in order to build a tool for both, the average household and authorities , in order for local authorities to better plan, better make decisions and provide knowledgable information in order to save lives. _ Additionally, I have been personally affected by a similar situation, providing me better insight regarding the experience.
What it does
There are three main components of the app. These components help the user learn how to prepare for natural disasters, provide a feed of visual and statistical updates from the national weather association and provide a location tracking system to let others around you know if you are in trouble and also sending this data to the backend where it is stored and local authorities would be able to access It to help find you and save you in a time of distress.
The first part is the NWS feed where we have a visualization of the United States and the current weather reports for various regions. We are able to see the various reports and visual charts and graphs representing this data at our current location.
The second part is the location tracking system. Here we have a map UI where we see our current location being displayed on the map. Our location is automatically sent to the backend and it updated in realtime. Here we see my location down in Michigan. If I go ahead and press alert, the app will put my location in alert status. This means all users around me in a 10 mile radius will be able to see that I am in trouble and will be able to help me. Additionally, this alert status is sent to the backend where local authorities see that you need help and have access to your exact location. This navigation-precise location data can also be used for determining actions such as entering a house on fire. For example, if the firefighters don't know whether someone is still inside the house or not they can simply view the app and see whether they are in or outside of the house.
The last tab is the resources tab where there are a plethora of resources for various natural and unexpected disasters which users can use in order to be prepared and aware of how to tackle such situations.
How I built it
I built the application using react-native and expo sdk. I also created the location tracking system using a a Firebase, geolocation and geofencing to alert other users around them. I user the NWS api to provide their UI and for the resources tab I created it and applied the resources I found.
What's next for BEFORE AND AFTER
I hope to implement this app and release it to the App Store and create a final product and involve local authorities.

Inspiration
We were brainstorming about problems and disasters in the world, and we realized that one of the biggest problems was earthquakes. We thought of it some more, and we came up with the idea of a website that could track earthquakes
What it does
The website has a map that shows all earthquakes within the last 30 days. the strength of the quakes are color coded, with red being the strongest, orange being moderate, and yellow standing for weak or insignificant.
How We built it
We split it up into parts. Rashmit would do the web dev, Chris would code the map, and Alex would do the video and the words.
Challenges we ran into
We had a bit of trouble with the time limit, and we had to cut some of the features that needed more time, like the earthquake simulator, which would be made in Unity, and the live chat.
Accomplishments that We're proud of
We're just glad we were able to make it! We learned a lot from each other.
What We learned
Earthquakes happen a lot more than we expected, and we hope to raise awareness about how you can stay safe during an earthquake and donate to people in need :

The game screen
Inspiration
My inspiration would be my younger siblings. I see that they prefer watching things and playing games, so probably books and research is not their cup of tea. They are also young, so they lack knowledge regarding the natural disaster topic. I thought to myself, "what if there is an app that can teach them about safety during natural disaster and still be entertaining for them," and so a game app came to mind.
What it does
The Hidden disaster app allows you to play a game, where you look for the hidden natural disasters, and once you find them, it will take you to a different screen to learn about it. The purpose of this app is for people to enjoy playing a game and learning at the same time.
How I built it
To build the app, we used App Lab in code.org. We used design mode to create the majority of the app and then we coded it the way we wanted it to function. We googled natural disaster images and used them within the app.
Challenges I ran into
We tried to combine different buttons in an on event using "&&" because after clicking the buttons, they all lead to the same screen. When we coded that, there was no response after clicking the buttons. It didn't do what we had wanted it to do. We had a little difficulty on how to make the code shorter and more easy to read. Then we figured that we can create a function and call it anywhere in the game whenever we need it. This made the code more organized and understandable.
Accomplishments that I'm proud of
Personally, I am very proud of the entire application. I am proud that we were able to make an app that can actually be played by ourselves.
What I learned
When doing this project, i learned that first, when you put your mind onto something, it can be accomplished. No matter how long it takes. I learned to be patience and not give up. I even learned more things about design mode.

As the pandemic continues to aggravate, it was hard for everyone to keep it under control as it was difficult for people to recall their whereabouts for the past 14 days. Nevertheless, an old man who was infected could recall every location he’s been at for the past 14 days. This greatly helped to keep the pandemic after control as those “high risk” individuals that were in close contact with him could immediately be sent to self-quarantine or receive a Covid-19 (Nucleic Acid) test. However, it is quite rare for people to recall exactly where they’ve been for the past 2 weeks, so we thought of the idea of creating an APP that could help remember where you’ve been. A tracking APP that would record down where you’ve been would be almost unrealistic as it interferes with user privacy and may contain numerous personal information. Due to this reason, we decided to create a contact tracing app that is based on public information and does not contain any personal information.
What it does
We created a contact tracing app that utilizes MAC Addresses to record and contact those who have been in contact with an individual. Each device has its own unique and permanent MAC address which does not contain any personal information and is accessible to everyone as it is automatically sent to a WIFI router to establish a WIFI connection. The moment you connect to a WIFI, the app will record all MAC addresses that are connected to the same WIFI network on a local file. If a user becomes a confirmed case, they could choose to send their list of MAC addresses saved on their local file into the online server which will mark these MAC addresses as “high risk.” Our app would also be able to differentiate between MAC addresses inputted by the hospital or an allegedly confirmed case. When a user wishes to check if they have been in close contact with a confirmed case, the app would compare the user’s MAC address with all the other MAC addresses that have been marked as “high risk”. By using the MAC address and WIFI network, this APP would greatly help minimize the spread of the virus while protecting other’s privacy.
How I built it
Throughout the process, we communicated a lot on deciding how we should code and what functions should the APP include. We started simply as we brainstormed an APP that could record and send MAC addresses. Soon, we realized that extra precautions would be needed to protect users’ privacy and more functions should be added to the APP to better resolve the difficulty brought by the Coronavirus. By adding more features little by little, our APP eventually turned out to be the project we are presenting to you.
Challenges I ran into
The 3 major hardships we went through while creating this application was during the planning phase, the cloudant documentation, and the part when we first started to compile our codes into an APP. While planning and coding for this APP, we were very concerned about user privacy and how to protect our users’ privacy. To prevent impersonation and others from hacking our website, we made sure that we had precautions to stop things like this from happening. For example, our application would only contain users’ MAC addresses. Our server would also automatically ban anyone who attempts to access the admin section without the correct password by IP for 15 minutes. It took us some time to both code and come up with ideas to avoid people from maliciously attacking our server. The cloudant documentation was often ambiguous which served as another major problem that we had to overcome. Lastly, compiling our code into an APP was the 3rd major challenge we went through. We contemplated whether we should keep the function or delete the function, whether we need to add anything, and whether the compilation would be successful. There were several things we were concerned about and worried about, but we were glad that the compilation worked in the end after several alterations to the code and several tries.
Accomplishments that I'm proud of
We are all very proud to create this app and participate in this competition. Although the whole process was tough sometimes, it paid off well. When we ran our code, the feeling of accomplishment was overwhelming, and we were definitely glad that we never gave up.
What I learned
Although we were familiar with the different computer languages, it was our first time creating an application by ourselves. In addition to learning the creation of a mobile app and the systemic usage of Github, we also truly understood the power of computers and their real-life applications. After this experience, computers are not just a bunch of variables, numbers, and strings anymore, and we clearly understood how computers are helping us in real life.
What's next for Contact Tracing App
To support additional users and to support the iOS platform, we'll need to upgrade our servers in terms of RAM and storage by upgrading our IBM Cloudant DB and Cloud Foundry services. Further functions and features may also be added to our application for future use.

The recent coronavirus had bought the entire world to a standstill. I wish to bring about a small change to this scenario and that was what inspired me to build this app
Doc@home
The spread of the pandemic has caused a lot of changes in our lifestyle, people fearing to get outside their homes, transportation almost shut down and social distancing becoming all the more important. The three major health issues that we face during this pandemic are
the deterioration of mental health due to lack of socialization
difficulty in getting medical appointments due to travel restrictions
the uncontrolled spread of fake news.
Doc@home is a web app build with an indention for helping to cope up with the current COVID situation.
The app has 3 main features:-
1. Became an AI companion for those in quarantine
“Connectedness is important to all humans, so I think we are all at risk [of loneliness during quarantine],”
- Deborah Roth Ledley, PhD, a licensed psychologist in Pennsylvania
The new reality of prolonged quarantine period and lack of socialization with other family members, friends and managing the fear of contracting the virus and worry about people close to us who are particularly vulnerable, are all challenging for each one of us. While the physical impact of COVID-19 can be assessed and treated, the mental impact is often ignored. Many people are experiencing emotional breakdowns and having depression. The new reality of prolonged quarantine period and lack of socialization are adding up the mental struggle.
More than 50% of those suffering from mental health issues are not seeking treatment, due to social stigma.
This present environment in the country has increased stress and anxiety amongst the citizens.
Introducing to you Jessica, your very own AI companion. Jessica can help you overcome your isolation and loneliness.
2. Provide a connecting medium for doctors and patients
But sometimes a chatbot might not be enough. You might need to seek professional help
The fear of traveling has resulted in the hampering of checkups of many people.
Doc@home, helps patients to take their routine checkups from the comfort of their homes without the scare of the virus.
It helps any patient to connect with the doctor of their choice, from the list of available doctors, and book an appointment according to their convenience either in offline or online mode.
The app has 2 portals, one for the patients requiring the appointment, and the doctors available for consultation. The patients can enter their medical history, any undergoing medication, etc which can be viewed by the doctor if he/she confirms their appointment. The index page of the patient and the doctor shows all their upcoming consultations. The doctor is notified if there are any patients requiring their appointment, and have the option to either confirm or deny, which causes a corresponding notification to be sent to the patient.
The doctor can also send the prescription with detailed feedback to the patient after consultation, along with the consultation fee to be paid. The patient can view the feedback in the history tab of their portal, which also provides the facility to pay the consultation fee by redirecting them to the Google Pay web page.
3. Create a forum for discussion between ordinary users and doctors
Another big issue that we face during this time, is the spreading of COVID related fake news. News with no scientific basis like standing in sun can kill corona and your pets can spread CoronA are rapidly spreadly
It is estimated there over 800 deaths have occurred due to WhatsApp fake msg
Doc@home also tackles this issue
I have created a forum (inspired by stack overflow website) that could help people differentiate fake news from the real ones. Here people can raise doubts regarding different aspects of COVID and get answers from professionals. It is a community-driven platform where doctors and ordinary people can meet and help each other out. This forum, to some extend, would help ordinary people seek professional help and advice, and use it as a methodology to separate
fake and actual news
Although, it isn't much this is a humble step from my side hoping to bring our world to normalcy with the pandemic on the spread.
Why Doc@home: The innovative and social impact
⚕️
Easy and affordable medical consultations, at the comfort of your home:
On average, a telehealth visit costs about $79, compared with about $146 for an office visit, according to the study. With doc@home users can consult any doctor 24*7 from anywhere in the world and the appointment scheduling process occurs in one well-organized platform so the endless back and forth communication can be avoided
📹
Get a detailed medical prescription from verified doctors:
After every session, you would receive detailed feedback from the doctor having all the details about the medicines to be taken, its quantity, the duration, etc
💊
One-stop solution to keep track of your medical history and remind you to take your pills:
The platform gives a track of all our past medical details and family heredity details. It also gives you an option to share this info with the doctor of your choice. Getting the medical history of the patient would surely help the doctor make better choices.
🧘
AI companion for managing daily stress, anxiety, and depression issues.
🤯
Combats the social stigma surrounding the seeking of help for mental health issues:
The chatbot in the app has the potential to be useful tools for individuals with mental disorders, especially those who are reluctant to seek mental health advice due to stigmatization.
📱
Platform to verify the truth behind viral messages surrounding health and stop the spreading of fake news
: The app provides a medium for users to seek professional opinions from doctors related to various COVID topics
Tech stack used
The backend of the project uses flask(python) and SQLite as the database
The front end is built on bootstrap, css, js and jquery
Future updates
Implement a blockchain payment system to bring more transparency and security to the system
Integrate Twilio API to create a bot, that calls you/sends a message to your phone 5hrs prior to the appointment schedule
Add to speech to text conversion in the chatbot. So instead of typing the queries, the users can simply talk more naturally with Jessica
How I built it
With sleepless nights and coffee :)
Tech stack used:
Flask, bootstrap, MySQL
Installation
- Fork & Clone the repo
- Install all requirements: pip install -r requirements.txt
- Run: python3 main.py
- Copy the localhost url (usually localhost:5000/) and paste in browser
Challenges I ran into
Configuration trouble, the difficulty is retrieving data from DB
Accomplishments that I'm proud of
That I completed the entire project on my own. That's a huge accomplishment for me. Even when the problem kept on coming, I still kept on going
What I learned
A lot.
I have learned how to integrate front end and backend in the flask. I also learned how to build a chatbot. The project also helped me sharpen my front end skills
What's next for Doc@home
Must work on the UI
A few silly errors still exist. Need to debug them
Need to improve the chatbot
In the forum section, I would differentiate the answers given a professional and a normal user (in order provide from authenticity to the answer provided by a doc)
Do some web scrapping to get more info
Add ethereum code to the payment (the payment between the doc and user) and also in the forum section. This would provide more transparency and security to the platform

About Us
Shreeniket, Agnik, Devin, and Johnny are all rising sophomores living in the United States. Although we have different interests and experience in computer science, we all wanted to create a project that truly helps our communities.
Inspiration
Fitness exercises are very beneficial to personal health and physical well being; however, they can also be ineffective and potentially dangerous if performed incorrectly by the athlete. Exercise mistakes are made when the user does not use the proper form or pose. With gyms closed due to the pandemic, more people have started doing home workouts and physical education classes for school have gone virtual, meaning that coaches have been unable to help their students correct their form. Making an app that can give instant feedback to users when they do an exercise and finding a way to teach proper form more interactively will solve these problems, and change the scene for athletic coaching entirely.
What It Does
Our app, Sportable, allows for students and normal users to submit short clips of themselves, which, using computer vision, detects if the form is incorrect or not, and what they have to change. Look at the
README.md
in the
video-classifier
section of our repo to learn how this works. Our app also has features allowing users to learn how to to do a variety of exercises using AR (augmented reality). Sportable has special functionality for schools, allowing P.E. teachers to organize classrooms and assign workout assignments, which can be submitted by students through the app. A better explanation of what Sportable does can be found in the demo. We also made it so that the echo AR uses natural language processing to display a 3D model.
How We Built It
In order to build a form classifier, we scraped workout videos from YouTube in order to train to create a dataset, as we couldn't find a public dataset that contained videos of correct and incorrect form. We then trained a neural network, based on an Inflated 3D ConvNet architecture, loosely inspired from
this research paper
. Here is a visualization of what the neural network looks like:
Even though the model had a state-of-the-art architecture, because the dataset was only a few hundred videos long, results were inconclusive and we didn't incorporate the model in our final demo. Again, Look at the
README.md
of the
video-classifier
section of our repo to further learn about the model, and why it didn't work the way we wanted. Because of this, we didn't show this feature in our demo.
In order to send videos and information from the app we implemented a server using with Node.js MongoDB. There are major routes designed to serve both IOS clientside and Web client side. Both clients submit to the same route, but web client side will also use GET request to retrieve html files. For authentication, we store JWT in the user's cookie, and conveniently IOS's alamofire library also allows for cookie storage.
For building the VR aspects of our app, we used echoAR, a great tool that allows us to easily create and deploy AR applications. We created the UI/app using XCode and Swift, and a login website using HTML and CSS.
Challenges We Ran Into
Creating our own custom dataset of common exercises with correct and incorrect form and scraping the web for those videos was a time-consuming and difficult process. Even though we got hundreds of videos eventually, we still need more data to build a more accurate classifier. Sending videos from the iOS app to the AWS server was also challenging, due to poor documentation.
Accomplishments That We're Proud Of
We're proud of finishing a complex project in such a short amount of time and hopefully making an impact on the fitness/athletic training community.
What We Learned
We learned how to make requests between iOS client to an AWS server, as well as video classification with neural networks
What's Next For Sportable
Hopefully larger exercise form datasets will be created, so we can retrain our model and make it more efficient, as well as detecting a wider variety of mistakes in common exercises.

10,483 | https://devpost.com/software/interestmonitor | Inspiration
We were inspired by the current struggles of remote learning caused by the pandemic and observed that a high rate of students were lackadaisical and distracted. This program aids the teacher in monitoring the students’ activeness within the online environment.
What it does
The Interest Monitor tracks the students' eyes to assess the attentiveness of students. If the scholar slacks for over 10 seconds, the teacher is alerted so that he or she can gently remind everyone to focus on the topic at hand. More information found here:
https://sites.google.com/view/interest-monitor
How I built it
We streamed the Zoom window onto TKinter, strategically using OpenCV to track the eyes and conclude that the students are paying their fullest attention.
Challenges I ran into
We faced many challenges while putting this intricate program together. We struggled in restricting the code to detect our eyes only, and not the surrounding objects. By strategically using certain properties of a human’s face, we limited the program to only recognize the person’s true eyes, rather than the clutter of a scholar’s background.
Accomplishments that I'm proud of
After hours of arduous work, we have coded an effective tool to solve problems of remote learning. We are proud to present the Interest Monitor, the outcome of our teamwork and perseverance.
What I learned
Through the battle of putting together every little fragment of our project, our team gained the experience of working together to fit everyone’s talents, and pushing through the bumps in our code. We learned new ways to overcome complications with OpenCV and TKinter. This was an adventure fresh to all of us. It was phenomenal to experience this exploit together as a team.
What's next for Interest Monitor
The Interest Monitor holds great potential. In the future, this project could be improved to accommodate alternate major problems.

Inspiration
Resource extraction has tripled since 1970. That leaves us on track to run out of non-renewable resources by 2060. To fight this extremely dangerous issue, I used my app development skills to help everyone support the environment.
As a human and a person residing in this environment, I felt that I needed to used my technological development skills in order to help us take care of the environment better, especially in industrial countries such as the United States. In order to do my part in the movement to help sustain the environment. I used the symbolism of the LORAX to name LORAX app; inspired to help the environment.
_ side note: when referencing firebase I mean firebase as a whole since two different databases were used; one to upload images and the other to upload data (ex. form data) in realtime. Firestore is the specific realtime database for user data versus firebase storage for image uploading _
Main Features of the App
To start out we are prompted with the
authentication panel
where we are able to either sign in with an existing email or sign up with a new account. Since we are new, we will go ahead and create a new account. After registering we are signed in and now are at the home page of the app. Here I will type in my name, email and password and log in. Now if we go back to firebase authentication, we see a new user pop up over here and a new user is added to firestore with their user associated data such as their
points, their user ID, Name and email.
Now lets go back to the main app. Here at the home page we can see the various things we can do. Lets start out with the Rewards tab where we can choose rewards depending on the amount of points we have.
If we press redeem rewards, it takes us to the rewards tab, where we can choose various coupons from companies and redeem them with the points we have. Since we start out with zero points, we can‘t redeem any rewards right now.
Let's go back to the home page.
The first three pages I will introduce are apart of the point incentive system for purchasing items that help the environment
If we press the view requests button, we are then navigated to a page where we are able to view our requests we have made in the past. These requests are used in order to redeem points from items you have purchased that help support the environment. Here we would we able to
view some details and the status of the requests
, but since we haven’t submitted any yet, we see there are none upon refreshing. Let’s come back to this page after submitting a request.
If we go back, we can now press the request rewards button. By pressing it, we are navigated to a form where we are able to
submit details regarding our purchase and an image of proof to ensure the user truly did indeed purchase the item
. After pressing submit,
this data and image is pushed to firebase’s realtime storage (for picture) and Firestore (other data)
which I will show in a moment.
Here if we go to firebase, we see a document with the details of our request we submitted and if we go to storage we are able to
view the image that we submitted
. And here we see the details. Here we can review the details, approve the status and assign points to the user based on their requests. Now let’s go back to the app itself.
Now let’s go to the view requests tab again now that we have submitted our request. If we go there, we see our request, the status of the request and other details such as how many points you received if the request was approved, the time, the date and other such details.
Now to the Footprint Calculator tab, where you are able to input some details and see the global footprint you have on the environment and its resources based on your house, food and overall lifestyle. Here I will type in some data and see the results.
Here its says I would take up 8 earths, if everyone used the same amount of resources as me.
The goal of this is to be able to reach only one earth since then Earth and its resources would be able to sustain for a much longer time. We can also share it with our friends to encourage them to do the same.
Now to the last tab, is the savings tab. Here we are able to find daily tasks we can simply do to no only save thousands and thousands of dollars but also heavily help sustain and help the environment. *
Here we have some things we can do to save in terms of transportation and by clicking on the saving, we are navigated to a website where we are able to view what we can do to achieve these savings and do it ourselves. *
This has been the demonstration of the LORAX app and thank you for listening.
How I built it
For the navigation, I used react native navigation in order to create the authentication navigator and the tab and stack navigators in each of the respective tabs.
For the incentive system
I used Google Firebase’s Firestore in order to view, add and upload details and images to the cloud for reviewal and data transfer. For authentication, I also used
Google Firebase’s Authentication
which allowed me to create custom user data such as their user, the points associated with it and the complaints associated with their
user ID
. Overall,
Firebase made it EXTREMELY easy
to create a high level application. For this entire application, I used Google Firebase for the backend.
For the UI
for the tabs such as Request Submitter, Request Viewer I used React-native-base library to create modern looking components which allowed me to create a modern looking application.
For the Prize Redemption section and Savings Sections
I created the UI from scratch trialing and erroring with different designs and shadow effects to make it look cool. The user react-native-deeplinking to navigate to the specific websites for the savings tab.
For the Footprint Calculator
I embedded the
Global Footprint Network’s Footprint Calculator
with my application in this tab to be able to use it for the reference of the user of this app. The website is shown in the
tab app and is functional on that UI
, similar to the website.
I used expo for wifi-application testing, allowing me to develop the app without any wires over the wifi network.
For the Request submission tab, I used react-native-base components to create the form UI elements and firebase to upload the data.
For the Request Viewer, I used firebase to retrieve and view the data as seen.
Challenges I ran into
Some last second challenges I ran to was the manipulation of the database on Google Firebase. While creating the video in fact, I realize that some of the parameters were missing and were not being updated properly. I eventually realized that the naming conventions for some of the parameters being updated both in the state and in firebase got mixed up. Another issue I encountered was being able to retrieve the image from firebase. I was able to log the url, however, due to some issues with the state, I wasnt able to get the uri to the image component, and due to lack of time I left that off. Firebase made it very very easy to push, read and upload files after installing their dependencies.
Thanks to all the great documentation and other tutorials I was able to effectively implement the rest.
What I learned
I learned a lot. Prior to this, I had not had experience with
data modelling, and creating custom user data points. **However, due to my previous experience with **firebase, and some documentation referencing
I was able to see firebase’s built in commands allowing me to query and add specific User ID’s to the the database, allowing me to search for data base on their UIDs. Overall, it was a great experience learning how to model data, using authentication and create custom user data and modify that using google firebase.
Theme and How This Helps The Environment
Overall, this application used
incentives and educates
the user about their impact on the environment to better help the environment.
Design
I created a comprehensive and simple UI to make it easy for users to navigate and understand the purposes of the Application. Additionally, I used previously mentioned utilities in order to create a modern look.
What's next for LORAX (Luring Others to Retain our Abode Extensively)
I hope to create my
own backend in the future
, using
ML
and an
AI
to classify these images and details to automate the submission process and
create my own footprint calculator
rather than using the one provided by the global footprint network.

When the theme education was announced it brought back nerves. Education is often associated with stress, mental illness, anxiety, because of the affects of school.
The team was all at one point negatively affected by the current school system and the mental toll that comes with the average day of a high school student in today's world. We saw how that trend of poor mental health and mental health resources only continued and worsened in college. Research shows that a high school student has the same anxiety as a 1950's psychiatric patient. According to the ADAA, 31.9% of adolescents had any anxiety disorder. The second leading cause of death ages 10-24 is suicide. Anxiety is the top presenting concern for college students, followed by depression.
We have all experienced the stress that school has. The stats seem like just numbers but they reflect individual experiences that we know very well. We feel like it is an area that is also often stigmatized, which creating an app that addresses it openly takes a step towards destigmatizing mental health.
So we decided the most relevant application of the theme, because of how it related to personal, but shared experiences.
This app's goal is to ease that unnecessary stress that students feel.
What it does
This app uses machine learning and takes in data from a user's past test scores, their average study time, and any past failures to give a 95% accurate grade prediction. It also features a study time calculator which tells you how much you need to study to get the grade that you want, based on the EOP study formula inspired by UC Santa Cruz. It also sends automatically emails to you and your friends if your mood is less than ideal. Another feature is that you can insert a date and it will remind you, for tests and important events. And displays a massive assortment of mental health tips.
How we built it
All of the coding was done in Python:
The GUI:
We used kivy and kivymd to design the GUI. This was a good choice for us because, it can be used to write cross-compatible code. In the application of our App we would want this to be as accessible as possible, so it just needs to be complied in different steps to put in on Android and iOS.
Grade Predictor:
Trained LinearRegression model on datasets on UCI's repository.
Trained on the same attributes that are inputs in the App to improve accuracy.
Used pandas and numpy for formatting the data.
Stored model with best accuracy on .pickle file to be used within our app
Used sklearn for training and predicting based of our dataset
I learned about some use of machine learning. When trying to figure out what kind of algorithm to incorporate, I researched the broad applications of the algorithm in order to maximize accuracy of the datasets. Learned about Clustering and SVM, then to finally settle on Linear Regression.
MoodCheck:
created function to return a value -1 - 1, based on the mood selected. If the user had an email of a friend and the value got to -3, it would send an email to the friend using smtplib and a free gmail account created for the app
Challenges we ran into
When we decided to use kivy for the GUI we knew it was a leap, because none of use had used it before. The biggest challenge in the GUI was learning the custom kivy language, because we couldn’t start developing the GUI without some basic foundation in this.
Checking Input. We obviously had to check for user error within the input sections, but because of the way the kivy language ties into the main python file it makes it a huge learning curve on how to format things so that you can access elements.
Language Barrier, ---> Development Time
One of our teammates had not coded in python for a year. So that combined with learning a new language was a hurdle the team had to work around. Learning stages seem like areas where we would go hours without getting anything done, but then later get alot done. So it was a point of what in the original app idea do we have to cut? And then what can we keep? An all-nighter solved those.
The navigation drawer
There was an error in the source code of kivy that was beyond our knowledge on how to fix, but realizing in was a python version and error and not with kivy, was one of those little things that caused huge problems and hours in spending time figuring out things we didn’t do wrong (except the python version installation on the VM)
Accomplishments that we're proud of
The crown jewel for us in this application, although not being very technically difficult, was being able to learn the kivy module and still finish the project to what we considered personally as an acceptable state.
Machine Learning Algorithm.
I (Quentin), had not started coding until almost a year ago. I had not started coding til last year in CS class, but now that I finally learned how to implement a machine learning algorithm after seeing other people do it successfully and looking at them in utter amazement, being able to set it up and get it working for the application, gave me pride.
The Navigation Drawer.
The navigation drawer gave us so many problems. We had to have re-coded it at least 3 times, in three different ways. But this really goes back to the kivy language because we didn’t know how any of that worked, and didn’t do our homework enough to install the right version of python on the venv, once it was working with no issues it was such an utter relief.
What we learned
We learned the kivy language and more about python inheritance as an object oriented language. It also taught us alot about python and how it complies compared to other languages. But it will be a good skill for the future.
Anything is possible with enough caffeine. We couldn’t have done this without iced tea and coffee because if it wasn’t for an all nighter it wouldn’t be done.
The importance of communication. We caught ourselves doing the same thing twice because we weren’t talking as a team like we should’ve been. After having a team meeting, that solved things and we were able to research and work on our own parts better.
GitHub:
Two of us had never used github before. Now we know!
What's next for MindManager
Figure out cross compatible solution for the email sender. Possibly with a socket server set up.
Login Screen. This would create a form and store stuff in a server.
Display stuff on calendar and access permission from settings based on the os.
Cleaning up the GUI, making the colors change better where they need to, as we switch themes some buttons don’t switch. The little things like that to make the GUI as beautiful as it can be will help the application deliver better
Studytime algorithm would be more accurate as a sigmoid function. Figuring out how to find that in order to give more accurate results. We could also take more data points here
KeepToPurpose:
Stress Reliever Cards that give activities for whenever that user is stressed out.
ADMIN, USER relationships, so that schools could use the app, to care more about the mental health of the students.

Day Planner
Productivity Timer
Screen Timer
Inspiration
Productivity and Efficiency have been 2 of the mostly discussed topics in the recent days with the work from home situation and e-learning.
I've faced many issues like not taking breaks at all or being distracted too much. On somedays I don't achieve all the tasks because I don't have a proper plan, or because I forget the time to begin a task.
There have been many such issues that I've faced. Not just me but many others have faced such issues.
Yes, there are a significant amount of mobile apps that can solve these issues. But mobile apps aren't the best solution after all. Sometimes you get distracted by the phone when you try to open the productivity app, or you've left the phone in another room.
But I knew that an Alexa skill to solve these problems would be much feasible as you always have Alexa in the same place, and it's active all the time. Also using only your voice is more efficient
Therefore, I analyzed the best features of few mobile apps, and also added few features that can boost your efficiency into one Alexa Skill, and it was called
Uplift Efficiency
.
What it does
Uplift Efficiency is a very user-friendly Alexa skill that you can start using by just saying "Alexa, open Uplift Efficiency" to any supported device.
It consists of 4 main features at the moment.
• Day Planner
• Productivity Timer
• Screen Timer
• Challenges
Day Planner
Organize your day and keep track of the tasks in your day.
Add all the tasks in a typical day including Sleep, Work/School, Sports and Exercises, Leisure and Custom Tasks.
You can add the begin time and the end time for all these tasks, then we'll arrange all the tasks in an order and make it your daily routine.
Then you can set reminders for the tasks in the day plan.
You will be reminded when to begin and end the tasks in your day plan.
Also you can edit the day plan or refer to it at anytime...
Productivity Timer
Boost your productivity by properly organizing your work-break pattern.
You can choose one clock out of the 3 available clocks to begin with.
You can choose between Pomodoro timer, 52/17 timer, Ultradian timer.
After setting one default clock you can tell you work session. (Eg: "Begin a work session of 3 hours and 30 minutes")
Then reminders will be set at every time you need to switch from work to break or break to work.
These reminders are just like any other reminder on Alexa, but they'll be set up automatically.
Screen Timer
Take care of your eyes; take a break while using devices with screens.
Similar to the Productivity Timer you can ask Alexa to begin a screen session and you will be reminded every time you've got to take a break and get back to work.
This works according to the 20 20 20 rule, where you take a 20 second break every 20 minutes to look at something which is 20 feet away.
Challenges
5 Day Challenges to boost your efficiency.
Just select a 5 day challenge and get started. Currently only 1 challenge is available, it is the sleep challenge.
In the sleep challenge you need to do 5 tasks on 5 consecutive days before sleep.
More challenges will be added in the future.
Premium
There is also a premium version. Currently the only advantage for premium users is setting up 4 accounts. Non-premium users can use only 1 account. But more features will be added in the future for premium users and customization will be allowed for Premium users.
How I built it
The skill was built using Voiceflow, Google Sheets, Alexa VUI Developer.
How each of the features were built
Day Planner
The users task names, begin times and end times were captured into variables and stored in a Google Sheet. Then they were arranged into order in Google sheets, then all data was retrieved.
The feature to set reminders was easy with the Voiceflow Reminder block.
When editing tasks and updating tasks the data was updated in Google sheets too.
Although the day planner feature didn't use many advanced technologies or much custom tasks it required hundreds of speak blocks, variables etc.
Productivity Timer and Screen Timer
The hour and minute was captured into slots within the intent, if the hour and minute is not defined by the user, the user will be prompted to say the session (hours and minutes). Then the data was entered into Google sheets. Then the number or breaks and work sessions were obtained, there was some custom code here too. After this the exact time to take a break and get back to work was calculated and reminders were set accordingly.
Challenges - Sleep Challenge
Firstly the date to begin the challenge was asked, after that the time the user goes to sleep was obtained through the day plan. After which the estimated task time would be deducted by the sleep time and a reminder would be set to the time the user should begin the task on the 5 days.
Custom code was used to get the user's timezone.
Contact Feature
There is a contact feature which users can use to send us a message from the skill.
The user's email address will be obtained (The user will have allowed permissions before-hand). Then the message will be captured. A simple zap (Zapier) is used to send a confirmation message to the user's email. Even we'll receive a message saying an user contacted and we can reply.
Premium
A one-time in-skill purchase can be purchased by the user. When the purchase is successful, a variable called premium_user will be set to 1. Others will have it 0. So the premium features can be accessed by the user if the user's premium_user variable contains a 1.
The feature to create multiple accounts and switch between them is done by altering the user_id. But the real user_id won't be permanently altered.
Visual User Interface
The Alexa Developer Console has a feature to develop VUI's using JSON. I built the VUI for devices with screens using the Alexa Developer Console.

Retrieving Data and deciding the clock type
Menu
Challenges I ran into
Day planner: I ran into a problem when trying to create and retrieve data too often within the conversation. Alexa would reply with "The requested skill has an error" It was difficult to solve it so I came up with a temporary solution as I didn't have a lot of time. But I'll come up with a permanent solution later.
Day Planner: The feature to edit tasks was difficult to make. It needed over 100 blocks.
Productivity Timer and Screen Timer: After an user sets a reminder for the first time the data isn't deleted. Then when the user sets a reminder again the same data of the first time is recurred. Deleting data in Google sheets wasn't possible as too much interactions would prompt users to errors. So, I had to develop it so that if the user has set a reminder already the data needs to be updated and not created again.
Productivity Timer: The pomodoro clock has short sessions, 25 minutes or work and 5 minutes of break, so it was difficult to set a lot of reminders if an user's work session is long. Since it required a lot of reminders and even Amazon didn't allow so much I had to limit the work session to a relevant time.
Challenges: There was a issue with scheduled reminders in voiceflow. It wasn't an issue from my side, but a bug in voiceflow. So, I had to calculate the time until the task and set a timer reminder, which was difficult.
Challenges: Then came up an issue with timezones, because now() in google sheets takes the current time in my timezone, but users are located in different timezones. So, I had to add a custom code to take the users current time and record it in google sheets instead of now().
VUI: It was very difficult to design the VUI for echo spot devices, since this was my first time developing VUI's it was difficult to design it.
Accomplishments that I'm proud of
Firstly, I am really proud that I finished developing at least a beta version within the hacking time.
Also I am proud about being the first Productivity Voice Skill with this much of features.
Simply I am proud about everything in Uplift Efficiency and how much I achieved within a short time.
What I learned
As I've never used the Alexa Developer Consoles VUI editor before I learned to develop VUI's.
A lot in Voiceflow. I used almost all the features in voiceflow and learned so much that I never knew about voiceflow and what could be done with it.
I learned a lot more...
What's next for Uplift Efficiency
Uplift Efficiency has many more features to be added and I need to make few changes too.
After that I will submit the skill for certification.
I have also planned to launch the skill on Product Hunt, as it can bring a lot of users to my skill.

Planr - Time Management Made Easy
Planr takes all of your assignments and organizes them into an intuitive interface. You enter all of your assignments as well as when you have time to work on them, and any afterschool activities that you may have. Planr then tells you if you need to cancel activities or spend more time on it for that night. It then coaches you on creating better habits. All parts of the program are editable and allow for lots of flexibility.
Planr can be viewed on any mobile device that has internet access. As well as a future mobile app that we designed in the process (attached below).

Many young children and ELL (English Language Learners) may not have the help they need due to the current situation with Covid-19. Immigration to various countries is increasing and for those countries that have an official language of English, it is important that immigrants have the proper resources to learn the language.
What it does
This game is meant mainly for young children as well as ELL students. The
educational
purpose of the game is to help with learning pronunciation in the English language.
The game starts by displaying an image, as well as the number of letters corresponding to the word in the image. The user is given the letters of the word in a randomized order (as well as additional letters, which aren't needed!) to select from and is expected to write the word correctly.
How I built it
I built this program using C++ and the openFrameworks library in the Visual Studio 2019 IDE.
Challenges I ran into
The biggest challenge for this project was learning how to use the openFrameworks library with C++ for the first time. I had never used a library before and ran into several problems
Accomplishments that I'm proud of
Completing the project on my own, learning a new library and how to use a new IDE in less than 48 hours.
What I learned
I learned additional C++ syntax as well, new concepts such as random letter generation and seeding, and using libraries in C++ programs. I learned how to use the Visual Studio 2019 IDE as well as the GitHub publisher within it.
What's next for WellSpell
Improving the speed of the program, categorizing words/photos based on a theme (e.g. cow, panda, dog go into an Animals category) and pronunciation of the words after the user has completed typing the word.

10,483 | https://devpost.com/software/math-manatee | Insperation
We wanted to create a new and efficient way of learning math that people can study/review with.
What it does
Math Manatee lists topics that you generally see in math grades 6-7. Then we provide links to innovate and effective videos to help the kids to learn through better exposure.
How we built it
Most of our team had to learn a completely new language(HTML) for this project. We all agreed on our separate deeds, while on a call to communicate what we were doing.
Challenges we ran into
Most of our team had to learn a new language so that was difficult. We considered changing our project in the middle of the hackathon which was a predicament. We had to do the whole thing virtually.
Accomplishments that we're proud of
Like we said before most of our team learned a new language, all of our teamwork skills improved, and we learned how to use different platforms.
What we learned
How to use Discord, Github, Twitch, Visual Studios Code, and Notepad++.
What's next for Math Manatee
If we continue on this path, our next goal is to improve our website to make it interactive and more appropriate for a larger age range. Then to overall complete an interactive app once again for a larger age range.

A teacher's page for uploading and creating classes
A student's class management page
The timer for how long the student has their reward
An empty classes page for a teacher
A testing session
The webserver responsible for relay control
Inspiration
Our inspiration came from not only our own experiences, but also our peers who have had a hard time readjusting to online learning. As stressful as it can be for us, it can be even more hard for younger children who don’t know how to deal with isolated learning. We wanted to find a way to take this unnecessary load off of their young minds and allow them to gain a rewarding experience while gaining more information.
What it does
COVID Classroom is a learning platform that scrapes quizlet sets and teaches kids in a way that they’re more comfortable with. It is essentially a simulated classroom that uses an award system where the user has to study x amount of sets before a smart device allows them to turn on their video games, social media, etc. It holds kids accountable for the work that they put in, which allows them to be more focused with what their learning while being able to do fun snippets of the other things they enjoy. It provides a balance for cohesive learning. In the site, teachers can manage the classes they own along with the students in them, students are notified when they get added to a class. When they enter that class experience, a flash card type test is given, with immediate feedback. Each time a student answers correctly, they are given 15 more minutes on their device. When they feel like it is time for them to redeem the time, they can click a button on the class page, bringing them to a timer page along with posting a get request to the smart device api. This turns on a relay that controls the student's device, and shuts off after the timer.
How We built it
For Covid Classroom, we wanted the architecture to represent a teacher:student hierarchy. In order to do this, we created extensions of the default IdentityUser class to create a teacher and student class. The web scraping algorithm implemented used headers and get requests to obtain and parse quizlet sets into flashCard data types, holding the definition and the term. classroom classes were bound to these flashCard sets, along with their teacher and the list of students in them. When a student enters the testing environment, they are given a flashcard along with 4 random options from other cards. This was done through a shuffling algorithm along with the implementation of a static random class. SignalR was used in the testing page in order to supply real time updates every time the user answers. Websockets and get posts were used to apply the student's saved minutes to the raspberry pi webserver, which used RaspberryPi.Net to control GPIO pins on a relay.
Challenges we ran into
We had challenges learning how to come together to do our tasks when we are so far apart. However, we made sure to communicate effectively on how we will carry out our tasks, which allowed us to get our finished product! Another huge issue we ran into on the development side was the abstraction of student and teacher user classes, initially we had attempted the solution that allows generic functions for either student or teacher, but due to time and energy needing to be spent in other areas, went with a solution of implementing both non-abstractly.
Accomplishments that we’re proud of
We are proud that we were able to work together in such a short amount of time and get so much done. We are really proud of how the testing page ended up, it seemed to be the right amount of comfort and engagement that we were really going for.
What we learned
We learned how how to work together cohesively while being so far away from each other, and we learned how to designate tasks that best fit each of our skill levels. One of the members of our team was inexperienced with coding. However we found ways that still allowed her to contribute to our final product.
What's next for COVID Classroom
Even after the pandemic subsides, this platform can continue to be used for younger students to learn. We will migrate to online databases and publish online so that real students can utilize us, along with some UI tweaks to make it more pleasing :)

Navigating the world with disabilities, mental illnesses or physical illnesses can be more challenging. Knowing what’s around you can be particularly difficult. The more that we can do to mitigate stresses and encourage inclusion, the better. Leada is specifically designed to help the disabled by providing learning tools that are accessible.
Due to fewer priorities given by educational providers to issues that may support the disabled, anyone with a learning disability finds it hard to sustain a normal life and thrive in educational environments or practices. This is more common in developing countries, in areas such as curriculums, teaching and learning materials, infrastructure, environmental issues, and special programs such as sports and games.
Helping them lead a normal life can ultimately be our responsibility, and Leada helps with just that. It provides you a platform with learning tools that would help you converse with people having disabilities, as well as help the disabled carry normal conversations.
For the text-to-speech application, we used the HTML5 SpeechSynthesis API to get the computer to convert text to speech. None of us have ever used an API before, so trying to figure out how to use it was difficult. We used Google MaterializeCSS to create a quick CSS template for our website. For both the Text to Braille converter and Text to Sign Language converter, we took the user's input, took each character in the input phrase, and converted each single symbol, creating a phrase. For the game, we would take each picture of a sign language latter and assign it to it's corresponding letter. Then we would get the user's input and determine if it was the correct letter or not. The website was made using simple HTML,CSS, and Javascript.
For designing the mockups, we used Figma, and integrated it along with the website using a color scheme, for a clean and a minimalistic look.

10,483 | https://devpost.com/software/quicksource | javafx app
Inspiration
While we were finding an idea, we came up with a really large project where teachers could create a class and voice chats inside that class and etc. We thought that would be too large of a project to complete in just a few days, so we searched for problems in online learning and one stood out. It could be easily completed within a few days and is somewhat original. The problem was that teachers had many resources all on different websites, and it was tedious to navigate through all the resources, constantly switching tabs, and all that.
What it does
QuickSource allows teachers to create a class and add resources to that class. Students can easily access those resources within the app by joining a class with a UUID. It's basically a web browser but the teacher sets the links and destinations.
How I built it
We built it using java, javafx, and an aws ECL instance. Nothing too special here.
Challenges I ran into
Right after we finished building the client side GUI, we instantly ran into a problem where we didn't know how to include the javafx modules within the jar. We spent maybe an hour on this and finally solved it by doing.... We also ran into server to client communication which was a real challenge. During the day before, the day to submit, we had a feeling we wouldnt be able to submit our project, so we quickly made an extra website incase we dont make any progress at all. Though we settled on a simple solution....
Accomplishments that I'm proud of
Accomplishments my team are really proud of are creating a fully fledged GUI for the client side of QuickSource and creating a runnable application on the server side that can successfully communicate with the clients.
What I learned
This was our first time actually creating an application that includes server to client communication so we learned alot such as most of javafx, server - client communication, etc.
What's next for QuickSource
We don't really plan on updating QuickSource in the future as we only really made it for the hackathon. Might pick it back up in the future as this problem is one we face alot and keeping track of where everything is becomes a hassle.
DISCLAIMER
The application on github does not work as my team ran out of time creating it. The video shows an actual runnable application that can be used though i made it on a seperate branch and that branch wont be visible until a bit after the hackathon deadline.

Open drawer with "A Disinfecting Box"
UVC light for "A Disinfecting Box"
Disinfecting cash with "A Disinfecting Box"
Inspiration
I was inspired to build "A Disinfecting Box" because I found out that even after you take a shower or wash your hands, touching or even just smudging a dirty surface can get your hand completely dirty. These dirty objects could include items such as your phone, cash, glasses, and school/work supplies.
What it does
"A Disinfecting Box" is a cardboard box with a drawer, that contains a UVC light. With the press of a button, the light can turn on and kill away all of the germs.
How I built it
I built "A Disinfecting Box" by first grabbing the materials needed, two cardboard boxes, a marker, an Exacto-knife, a hot-glue gun with sticks, a ruler, and A UVC light. I then grabbed the ruler and started to measure the cardboard pieces needed to make the drawer and outside box. I then made a handle out of hot-glue and glued together the pieces for the drawer and box. At this point, I had a working drawer with a handle that I could store things inside, but I wanted a disinfecting box. After that, I added a UVC light, because It was the cheapest sanitization process that worked very well and was used to clean water in third world countries
Challenges I ran into
At first, it was hard to find a UVC light on amazon that was within my mom's budget for me, but once I got one it was easy to do the building process.
What's next for A Clean Freak
If I win any competitions with this project, then I will start testing how long items should stay inside for proper sanitization. I will also start making more working prototypes and find a reasonable price to start selling these with. This product will be targeted to
households
(cleaning phones and glasses ),
workplaces
(supplies such as pencils, staplers, pens, and rulers), and
small businesses
(to clean cash, coins, and credit cards).
I would like to thank my mom for buying me the supplies needed for building this, and the host of this competition.

Inspiration
We got inspiration from many children not being able to attend a school or have difficulty reaching school. These children have to face many problems to participate in a source of education. So we asked the question, “How can these students concentrate on their studies when they have so many other distractions?” To solve this problem, we created a way for students to learn without having to travel to school. Children can stay in their homes and use our online, and also an offline resource - XTra Learn.
What it does
XTra Learn teaches children basic math operations and world capitals with python. You can learn about addition, subtraction, multiplication, and division in the math part of the project. You can also learn your world capitals in the geography part of the project. In the capitals section, anyone can add to the database of capitals by entering the country and its capital. We used pickle to accomplish this.
How we built it
The program was built using a combination of Repl.it, IDLE, and VSCode.
Challenges we ran into
We forgot that you have to use ‘global’ to use outside variables inside a function. We had to fix this to make the program work. We also forgot to call the primary function at the end. This error made absolutely nothing work, and it took us a minute or two to realize that we made that mistake.
Accomplishments that we're proud of
We’re proud of how we efficiently created this program by splitting up the work and combining it at the end.
What we learned
We learned more about Python, Repl.it, IDLE< and VSCode, all of the programs that were used.
What's next for XTra Learn
We hope to be able to add more features and more courses so you can learn even more from the program. Some of these include US State Capitals, advanced math, and even totally new subject like World History or Science.

Resources on how to save endangered species
Inspiration
When we started the hackathon, we were scrambling for ideas. One of our ideas was an application that uses echoAR to create a graph that displays the number of cases in your region. After experimenting with echoAR in android studio nonstop for more than a day, we decided to scrap this idea since it was too complicated. However we used some of the things we learned from this process and incorporated it into our website. As a last resort, we started brainstorming for new ideas, and we learned that there are many endangered species in the world. We knew we wanted to raise awareness for these species, so we decided to create a website that highlights regions with tons of endangered species, spreads awareness, encourages the user to help, and uses echoAR for AR visualization.
What it does
Our website has many parts. On the home page, we created a custom google map that highlights regions that contain many endangered species. It ranks them on a scale from most endangered(red) to least endangered(green). We also included a “What You Can Do” page, which has links to GoFundMe pages, petitions, and infographics so the people who view the website know what they can do to protect these endangered species.
How we built it
We used HTML, JavaScript, CSS, Bootstrap, and echoAR to create our website. We created our website using the repl.it IDE.
Challenges we ran into
When we started the hackathon, we tried using echoAR on android studio. We had to ask many questions on the echoAR slack, and ended up scrapping our idea after a day of nonstop troubleshooting and problem-solving. Halfway through the hackathon, we decided to create our website about endangered animals and ended up using an AR QR code from what we learned the previous day. Additionally making the 2D map into a 3D object for echoAR was challenging, and we ended up using Microsoft 3D builder. Time was also a big concern.
Accomplishments that we're proud of
We are proud of using echoAR on the website and creating a 3D model of the map. We are also proud of creating a custom google map, and creating our website as fast as possible( in like 4-5 hours!
What we learned
We learned that making an application on android studio using AR is very complicated, and we need to become more experienced with it. We also learned about the number of endangered species in the world, and how that number is troubling.
What's next for Save Dem Animals
In the future, we plan to refine the map and add more to the What You Can Do page. We hope this raises awareness for endangered animals.

Have heard many parents complain about how difficult it is to teach kids. Also, pre-schoolers getting lost due to a lack of support. Our goal is to solve the problem by putting the parent at the center of child learning.
What it does
"My Digital Mommy" is a digital learning platform specifically designed for pre-schoolers. The learning platform ensures that parents are in control of the child's learning process. As a parent, you get to not only decide what your child learns but you also control how much time they spend on each of the activities. This is important because we strongly believe there is no one size fit all education or learning. Who knows better than a parent on where the child needs to focus on. As a parent, you can also allow your child to play some learning games through the platform. You are truly in control.
Now coming back to the most important audience of the "My Digital Mommy". The child. The interface is designed specifically for preschoolers. Its easy, simple, and fun, and most important it's relevant as it's designed by the person who knows you most.
While building the platform our team focussed on scalability too. The learning content can come from a variety of platforms and technology.
In short "My Digital Mommy" is an attempt to have personalized learning for preschoolers delivered through the person who knows the preschooler the most.

10,483 | https://devpost.com/software/assist-g3ep2d | In these challenging times, our generation is very involved in the societal conflicts we face. However, those who want to join the movement often struggle on where to start and how to join. This app allows you to join peaceful protests near you which we find through Facebook and Twitter posts. This was my first time using Figma to design something, but after getting used to the basic controls, it was smooth sailing from there. Not only that, Figma also offers a feature that allows you to transform your designs into real code, making it much simpler when I build the real app. Before making the home screen, it was very difficult for me to find inspiration on what the app should look like, color scheme, etc.. But after finishing the home screen, it gave me motivation and an idea of what the finished app should look like. All in all, I am really satisfied with what I've designed in the last 48 hours.

Inspiration
Because of the corona virus pandemic, the way students receive their education has changed drastically. To protect student and faculty health, many schools have started online learning programs. As students ourselves, we realized that while online systems help slow the spread of COVID-19, it also presents many other problems. Based on our own experiences, we agreed that sitting for hours in front of a computer often took a major toll on our health. We all related to the headaches, muscle pain, and eye strain that followed after a long day of online school. So, we decided to use this hackathon as an opportunity to improve student life for ourselves and fellow students learning from home.
What it does
Timevity combats the issue of sedentary lifestyles among online school students and prevents health problems like eye strain and chronic back and neck pain. Timevity works by offering a helpful alarm that reminds students to take a break from their schoolwork as well as an exercise generator with recommended physical activities and routines.
The Timevity alarm is different from most standard clock applications because it can be controlled by both buttons and a motion sensor the team developed. The user's hand signals are detected by the user's camera and certain motions are used to stop or reset the timer.
The camera and motion sensor feature of the Timevity alarm is extremely helpful, especially in virtual schooling. Students will be focused on their classroom assignments and using other applications to communicate with their teacher. As a result, a motion-controlled alarm removes the hassle of switching between applications and manually clicking buttons to control the timer.
Next, Timevity offers an exercise generator along with recommended exercises. The exercise generator works by picking from a list of simple activities and randomly selecting an activity for the user to do. Along with the generator, the Timevity website includes longer 10-minute routines as well that the user can scroll through and decide to participate in. Timevity includes YouTube videos for each routine along with short descriptions of the workout sessions and what health benefits they provide.
How We built it
We built this project using HTML and CSS for the front-end and JS with node.js for most of the back-end. We also created the bulk of the website using the repl.it IDE and the motion sensor code with Visual Studio Code.
After both projects were complete, we combined the two projects to create the final Timevity product.
Challenges We ran into
One of the major challenges we faced during the creation of this project was putting the website and the motion sensor code together. This was our first time working between two separate IDEs so there was a lot of confusion on how everything would be put together.
In the end, we decided to use Github and Heruko to put all our files together. Initially though, we had trouble deciding what programs we would need to combine our work and we had to experiment with various alternatives.
Accomplishments that We're proud of
We're proud of the overall appearance and functionality of the Timevity website and we also feel really satisfied about the concept of the project itself and we think it has the potential to be useful in our own lives and in the lives of other students because it effectively fights a real issue in the modern world of education.
What We learned
We learned a lot both as individuals and as a team. We had some members who had never used VSCode before and others who were new to repl.it so we all learned the basics of different IDEs and expanded our knowledge in languages we already had experience in as well.
One of the front-end team members also created animations for the first time with CSS and learned about a handful of new properties to help polish the website.
What's next for Timevity
In the future, we hope to add more exercise routines to our recommended list and to the exercise generator. We're also planning to improve on the Timevity alarm so we can add more hand signals and give the user more control over the program.

I get inspired from mentors from all around the world who gave from their knowledge and wisdom to quarantined people and pushed them to learn more and spare their time on doing beneficial things instead of surfing the net and losing energy in silly stuffs. Also, the Technology is the future! so everything is easy to take and it's between our hands, why not encouraging for digitization!
What it does
It's a platform represents online courses in the IT and Technology domains, its main target is to make distances shorter and create a harmony and a communication between members hence, feel united together.
How I built it
I built it with passion! I considered it as a real project for me, I planned well to it, I sought for advices, I tried to improve my skills by attending the workshops, then I started coding; I tested 3 programming languages but I finally used JavaScript and,HTML5 and CSS3 for the pages structure.
Challenges I ran into
I used to find a technical solution for Education and how to practice it in different ways, I was patient, I challenged myself by working alone and face my fears, also, I came out of my confort-zone. The code doesn't run at first time and I repeated all the work so I get stressed but I defeat it and created a motivating and a dynamic atmosphere.
Accomplishments that I'm proud of
Although all the struggles I faced especially with the lack of ressources, I'm feeling so honored to be here firstly and to achieve other accomplishments during this work such as; counting on myself and reaching the top in no matter situation. I get sure that I'm a responsible one and my parents too were grateful for this. This is one of the best experiences in my entire life.
What I learned
I've got that sudden hunger for information, I try my best to gain time and make a progress in my soft-skills and my hard-skills. I learnt how to manage my time, my stress, how to improve my programming skills and how to communicate with people with several cultures.
What's next for ATAST CLUB
I'll continue envolving this project and I'll incubate it to not let it fade away. Moreover, I'll promote it to benefit all my entourage and the teenagers around me to make our generation better and be a spreader of knowledge.

Inspiration
The two of us are avid readers and we wanted to find book clubs that we can join, but there really isn't a application for that. So we developed this application to ease that process and to help users make lasting relationships.
What it does
This application allows users to find, create, and join rooms to talk about specific books or just literature in general.
How we built it
We built our app using the Vue.js framework, express.js / node.js for our backend, and socket.io in order to send messages between people.
Challenges we ran into
Because Matthew didn't test code before doing the frontend using something like Postman, we ran into issues that we thought were problems with the frontend. One of us wasn't familiar with frontend development, so there was teaching and yelling.
Accomplishments that we're proud of
This was our first time creating a chat application and we are proud to have learned more about web development from this.
What we learned
Creating this project has taught us more about how a chat app functions. Another important lesson we learned is that it is important to communicate with your partner if you are working on any application of sorts to understand their code. Finally, we learned more about problem solving and utilizing the tools that are given to us.
What's next for Bookific?
We plan to add quality of life features to Bookific to make this application feel more comfortable for users such as UI/UX changes and just other features in general to make the application feel more vibrant.

10,483 | https://devpost.com/software/sage-t90kni | Inspiration
Sage was inspired by a passion to create a platform that connects people with shared interests in order to communicate live. While scrolling through social media posts and group chats connects you with people around the world, there is no effective way to text and video chat with a group of people who share your interests in a specific topic. We aimed at a simple, but impactful solution. By creating a discussion platform that allows users to create and join temporary rooms with live chat, group video calls, collaborative white boards, interactive code playgrounds, and a vast multitude of alternative collaborative mechanisms, we were able to connect individuals willing to discuss topics they feel passionate about. While it is wise to learn from experience, it is wiser to learn from the experiences of others, and with a passion to create a more powerful social environment and bring people closer together in the light of this pandemic, we created this powerful platform.
What it does
Sage serves to fulfill one task: make a powerful live topic-based discussion platform. Biding by this mentality, Sage brings the act of collaborating and chatting with users into an intuitive interface. Users can use Sage to talk through text channels, voice channels, and drawing rooms with all the users who share your interests With Sage, users can create and join discussion rooms in order to create a curated feed of relevant rooms based on Facebook group interests and custom-input matching tags tailored to each user. Users have the ability to add and remove tags in order to better match them with rooms that match their interests. Sage takes the task of learning from new people and forging new experiences in a time of need and transforms it into an enjoyable task as numerous features simplify the job at hand while providing an elegant UI.
How we built it
Sage was built on a variety of technologies. Initially, front-end design was done using Diagrams.net for rough, preliminary planning, and later with Figma, focusing on the major parts of the app. From there, our team split up front-end work and back-end work amongst ourselves. The Front-end was built primarily using React and MaterialUI with the integration of Facebook for Authentication as well as the possibility to get generic data to help create “recommended tags” for users on our app. Furthermore, our real-time communication and collaboration mechanisms were set up through an Express server with Socket.io implementation. This allowed us to transform what would have been a very static format of communication into a more dynamic, interactive experience. The data was stored using Amazon Web Service’s Relational Database Service - specifically through a mySQL database and PHP for our API routing and endpoint creation. Communication between the front-end and back-end was done using JQuery, and we used domain.com to get a custom domain for our API as well as the web application itself.
Challenges we ran into
Sage ran into a few challenges with fleshing out t working with the Facebook API as well as with React and mySQL. Our team had a little bit of experience with React and mySQL so it wasn’t too bad, but we ran into a lot of small errors that had seemingly no plausible cause, so we ended up spending a lot of time on something very minor yet crucial. The React development process was especially slow at first due to some issues with project setup in the beginning, but we quickly gained momentum. In addition, we ran into the problem of running out of open API calls from Facebook, as we initially had an inefficient system for authentication and data retrieval. We lost a large amount of time in trying to explore some very new territory and argued about giving up that functionality, but ultimately decided that we would keep trying because exploring new territory is what a hackathon is all about! :) Eventually we were able to figure out how to use the APIs and it turned out even better than we expected. With cooperation and teamwork between all our members, we were able to turn difficult situations into memorable ones.
Accomplishments that we are proud of
Sage was actually the first time a few of us encountered/actively used technologies like Socket.io and Express and that quickly became a fulfilling experience in itself. Furthermore, considering the time span, it was both stressful and exciting to learn these technologies to get to development as soon as possible while retaining the information for later use. Most of all, as individuals who have done hackathons in the past and seen our share of failure, we felt extremely proud about the amount of code that we ended up getting written and the functionality that we were able to implement. Of course, there was still more that we wished to have done, but when compared to the first hackathon that we had done together, the progress that we made in becoming a more functional team over a mere three hackathons really showed The UI design aspect in particular shined in our project which was an equally pride-worthy moment. In addition to that, we were very, very happy to get the functionality down for real-time messaging and drawing boards within each class. It was a struggle, but the fun and worry in pulling something off at the very, very last second was an amazing experience for us all.
What we learned
As a team, we undeniably learned many new things about newer technologies that shaped the course of our project. Outside of our code, we learned more about the time constraint and the importance of planning/sticking to the plan. We saw ourselves drifting towards more ambitious goals, but learning to stick to the essentials and create something that simply works was a great learning. In essence, we learned the importance of making a product that is impressive, scalable, and dynamic in order to maximise effectiveness. In terms of technologies, we learned how to better use Socket.io functionality, Express, and React alongside how to work well collaboratively in order to host our web application and store data in the back end. Alongside that, as we were starting to run out of time, we were forced to step out of our comfort zones and take on new, different tasks.
What's next for Sage
Sage definitely has the capacity to go much further than it is now in the form of extra features and integration. While we have added Facebook signup integration, we could also use Facebook’s Ad Interest API to automatically create relevant tags to personalize content. We could also add more features, such as screen sharing, and integrate other services into the app, making for a richer experience, such as notifications, mentions, and file sharing. With these features, we can allow for a much better user experience and stick with our core mission of bringing people together in a fun, interactive, and dynamic manner to help build connections.

Inspiration
Many people often struggle to decide what to make for dinner. Additionally, many people often don't venture out into different cuisines or variations of the dishes they eat.
What it Does
Recipeas attempts to solve the above issue by providing users with a personalized search engine. Simply put in one or more ingredients, and you will be provided with a wide variety of recipes of different type and cuisine. This will help people save time during thinking of what to make for dinner, and allow people to try different cuisines and food items that they may not have thought of.
How I Built it
The app was built using React.js for the functionality and the front end. HTML/CSS and a little bit of Material UI was used to style the app. I also used the NPM Package Manager and Github for version control. The Edamam API was used to help get access to the different types of recipes.
Challenges I ran Into
It was originally tough to get the style to be in a presentable way, so it took a lot of trial and error to get it in a pleasant way that the user would have an enjoyable experience using.
Accomplishments that I'm proud of
I am proud of my ability to use the Edamam API, since it was my first time using the API
What I learned
I learned how to do several new styling features with React and CSS. I also learned how to manage my time and critically think.
What's Next for My Project
Since our goal is to make Recipeas a globally accessible website, we attempt to implement a few features to make our website more usable for all. This includes adding translations in a wide variety of languages so the website isn't restricted into English speaking users, implement features for dietary restrictions, and to add an "On The Go" Feature: recipes specifically meant for when travelling.

10,483 | https://devpost.com/software/science-bowl-preparation | Inspiration
While we were studying for the National Science Bowl, we needed a simple and efficient way to study science questions quickly and target our weaknesses to improve on. We scoured the web but we couldn't find the all-in-one tool we were looking for. So we experienced slower progress because of this. Because the theme of this hackathon is education, we decided it would be perfect to revisit this old idea. So we gathered our coding knowledge and got to work.
What it does
Through our program, you can pick what subject you want to work on (ex. Life Science, Math, Earth Science, etc,). Then, it will give you a science problem from that category for efficient studying. Once you want to switch subjects, you can simply press on a different category to improve in that area. There is also a quiz mode, where you can test yourself on all subjects for an all-around skill test.
How we built it
We decided to use python's Tkinter library for a visual experience rather than text-based. This way, it is easier to select modes and test yourself on the target material. This makes studying quick and productive.
Challenges we ran into
First, we tried to take on a bigger challenge than time permitted and had to decide what to remove and keep for optimum functionality. Some of the technical problems were the use of text boxes and window pop-up. We didn't let these technical challenges stop us and we persevered through the challenges. This hard work payed off in the end.
Accomplishments that we're proud of
We made a fully-functional user interface for science bowl preparation. This was a giant leap from the text-based interface of repl.com. We are proud of the project we created and learned so much from coding it.
What we learned
From coding a hands-on project, we learned so much. We expanded our knowledge about tkinter and visual python. We learned about text boxes, pop-up windows, labels, entry fields, and grid positioning. The best way to learn is through experience from hands-on projects.
What's next for Science Bowl Preparation
We will add a new section for the high school Science Bowl, as it is much more difficult than the middle school level. We will also add more tests and exercises to add more variety.

10,483 | https://devpost.com/software/coronadotcom-9noapv | Inspiration
We started our brainstorming with ideas on how we could spread education to all, and make it more accessible. After a few conversations and clashes, we decided to shift our focus towards a more coronavirus oriented project, which led us to coronadotcom. Coronadotcom started off as an idea targeted towards schools to educate them on how to safely bring students back to school. After a few more conversations, we decided that wasn’t the best idea because we aren’t the most qualified to spread that information. Rather, we chose a route thats main goal was to spread awareness on only the most factual coronavirus concerns and debunk false claims.
What it does
Our website's main objective is to offer only the most factual coronavirus updates in a clear and concise way. We provide a tool for countries to learn what works and what does not to control the spread.
How we built it
The main languages we used were html5, javascript, and css3. We laid out our frame with html5 and styled it with bootstrap 4. After the frame completed, we styled the page and made it very user friendly with css3 and bootstrap . The Around the World page was created using an open source JavaScript library for interactive maps, Leaflet. Using the library, we created a map with pinpoints on various countries, listing the number or COVID-19 cases, deaths, and how they are combatting the pandemic.
Challenges we ran into
Challenges we ran into as a team were that we unorganized and inexperienced at the start of the hackathon. Throughout the hackathon, we had to Google how to use Leaflet, an open source library. We also had trouble with bootstrap and css not displaying our text and media correctly.
Accomplishments that we're proud of
By far, the accomplishment we are most proud of is the map. Not only is the map interactive, but it has the # of cases and how safe each country is. We think the map aligns especially with education primarily due to our website proving what countries are doing well, and what strategies are working well to learn from. Another accomplishment we are proud of is the UI of coronadotcom. Our vision of the website was minimalism along with concise information to help improve awareness, and frankly, we reached that goal.
What we learned
Our team learned how to tackle projects together. This was our first hackathon together, and we were a little discombobulated at the beginning. As the hours went by, we learned how to work together, split tasks, and work efficiently. As novices, we learned more advanced css, like animating text and buttons with css and using open source libraries, like Leaflet.
What's next for coronadotcom
As we learn more about the novel virus, we will continue to update this page as it will prove to be beneficial to those who are in dire need of only the most factual information.

One pressing problem students experience, especially during virtual learning and the pandemic, is staying active. In school, students have mandatory Physical Education class, but the motivation to exercise during remote learning and social distancing falls off dramatically. So the challenge for us was: How can we encourage people to stay active while still maintaining social distancing rules? Our solution was Walk The World. Since many tourist destinations are now closed, such as museums or national parks, we decided to offer virtual visits as an end “reward” for walking, with various cultural landmarks along the way. In fact, we joked that it’s somewhat similar to Pokémon Go, one of our big inspirations. We realized this web app could help non-students as well, as they can have an incentive to exercise during the pandemic while learning about regional cultures and landmarks.
What it does
Our web app tracks the distance the user travels, and after certain checkpoints, a cultural or educational experience will be available. Under the homepage, the user is given a quick overview of what experiences our project hopes to create, as well as previews of educational incentives. Our second page, the how to page, breaks the process of tracking and earning distance down into a few brief steps and also reminds the user to adhere to social distancing guidelines. On the final page, the tracker page, the web app can return the number of miles already reached, and display how many more are needed to reach the goal. Checkpoints leading up to a final destination that corresponds to the goal distance are collected and screened to make sure they are above four star establishments (if there are none available that are rated above four stars, we provide a random one). Moreover, our project continuously looks for farther and farther establishments to ensure maximized distance and to provide newer experiences that the user may not have already encountered.
To illustrate what our web app does, here’s an example:
~Let’s say two of our group members start using our web app and go for a 6 mile walk. They choose Times Square as their goal destination and put in their goal distance of 6 miles. Our project will map a route ending at Times Square with a cumulative distance of 6 miles and arbitrary checkpoints throughout. For example, the route may look like this: Essex Crossing--> Hamilton Fish Park--> Tenement Museum--> World Trade Center-->...-->Times Square. These checkpoints are chosen randomly within the vicinity of the preceding checkpoint, and the cumulative distance between the checkpoints will be equivalent to the goal distance of the user. Our hope is that in this way, users will discover new places virtually and be motivated to walk and reach their goals.
How we built it
We first used
Figma
to create a wireframe so we could express the vision we had in our heads. We used Adobe Illustrator for designing the logo. HTML, CSS, and Javascript were used to create the user experience. Python was used as well to track the distance traveled and to retrieve data about nearby establishments, allowing the web app depth. To connect the frontend and backend, we used Flask with Python. We worked together on the web app using an extension called Live Share through Visual Studio Code which allowed us to simultaneously edit code. For those of us editing remotely, we used the Visual Studio Code extension Live HTML & JS Previewer v2 and
Repl.it
to preview the web app.
Challenges we ran into
Our team was not experienced in connecting the frontend design with the backend data, so we encountered many difficulties while trying to do so. In fact, we ended up not being able to properly integrate the two ends. We asked for help from Chris, a mentor, and were able to receive some resources to help with this challenge. Moreover, one of our group members mainly worked on the backend while the other two primarily worked on the frontend. This distribution of roles made it difficult for those of us working on the frontend (who were not very experienced with backend) to understand what the variables represented, what the key value pairs were used for, and how location data was utilized. We also had trouble organizing the preview images on the first page into an equally-spaced format with the same sizes. We tried several solutions with Flexbox and CSS grid, sharing resources such as Flexbox Froggy to resolve this challenge. A more general challenge we encountered was that for two of our members, this was our first hackathon. Our most experienced member gave several lessons and code walkthroughs to help increase understanding and knowledge. Moreover, attending the workshops, such as the Introduction to Github and Version Control workshop, was very valuable for learning more about hackathons, understanding concepts in computer science, and gaining skills. In general, when running into challenges, our approach was to communicate with each other, use resources, try different solutions, and ask for help.
Accomplishments that we're proud of
We’re extremely proud of our project, because we were able to utilize location to create a functional web app fulfilling our MVP (minimum viable product) in a short amount of time, all while getting to know each other. We had never worked together as a group before, so throughout the project not only were we hacking but also learning more about each other. We’re proud that we were able to create something that addresses physical education and virtual learning through cultural institutions and landmarks, parts of the remote learning experience that we are concerned about. We’re also very happy about how we handled communicating virtually, with Discord calls, sharing screenshots and examples to communicate our ideas, and collaborating through Live Share. In general, we’re proud that we kept an open mind and tried lots of new things during this hackathon, incorporating Google Places API, Google Geocode API and also attending workshops to learn about concepts new to us such as neural networks, data science, and AR/VR.
What we learned
We learned a lot about frontend/backend development as the majority of our team has never participated in a hackathon before so a project that contained this many parts was the first of its kind for us. Despite our inexperience, our team consistently made an effort to learn as much as possible. Thus, on Saturday night, when our web app had all of the essential components, our team spent an hour going through the backend code together, one of us presenting and sharing his screen and two of us watching and asking questions. This helped us all to reach a general understanding of what was going on with the backend and made the project and submission more cohesive. It was through our resilience in the face of challenges, that we were able to learn a lot about new languages and syntax such as CSS rules and Python dictionaries. While working as a newly-formed team, we learned about the strengths and weaknesses of each team member and assigned roles accordingly.
What's next for Walk the World
We hope to expand on our minimum viable product In the future, features we would like to include are the option to create password-protected accounts, a feature to race friends, leaderboards, more modes (users can select destinations as their start and end goals), a display of most popular destinations, and a feature to import data from Apple Health, Strava, Nike Run Club, and other apps/devices which track fitness levels. In general, we would like to improve the user experience by adding more fun and helpful features. We would also like to develop relationships with other businesses and educational establishments to possibly offer discounts as rewards for completing distance goals at those locations.

Inspiration
I was inspired to create a free, publicly available online composition notebook by the amazing
teachers
who were
paying out of pocket for school supplies
and the
nostalgia
I had for having a notebook in front of me in this period of learning online. In the recent period of learning online, I tried various note-taking apps to create and organize my notes online, but I found that I was not as connected to them as when I had to write in my notebook - and thus had a harder time
retaining information
. I decided to create the Online Composition Notebook project in order to recreate the experience of writing in a notebook; the notebook has a simple, elegant design and a typing method that forces you to carefully consider what you are writing because you can't just insert a character as you please. Most importantly however, this project provides an
alternative to purchasing school supplies
in an environment that students who are already learning online will have access to - enhancing their education.
What it does
The Online Composition Notebook allows people to
type and store notes online
. Each notebook contains a cover and 50 pages, and the user is able to modify the content of each of the pages. The typed content that the user can add to each page is saved as they flip through the pages. The user is also given the option to change how a page appears on their screen, with three different color choices on the left, three different font options in the middle and three different font sizes on the right. The notebook has a traditional feel, providing an outlet for nostalgia and a sense of normalcy in this crazy time.
How I built it
I built this project by using the
glitch.com
IDE.
HTML
is used to create the different elements on the page,
CSS
is utilized to set the general styling rules and
JavaScript
is used to add interactivity. The information on each page is stored by having an
array for each type of data that is stored
, and the buttons and typing are done by using different
event listeners
.
Challenges I ran into
The biggest challenge that I ran into was learning how to create this project with
minimal experience
in the coding languages that were used. I had not been exposed to any of the languages before for more than a few hours, so it was difficult to figure out where too begin. Each time I wanted to implement a new feature, I had to plan the semantics of what I was going to implement, search the internet using carefully chosen keywords and then learn the syntax for the code.
Accomplishments that I'm proud of
I am very proud of how I was able to make the entire notebook have a
comfortable, traditional feel
. I have missed having notebooks and being able to see the pages in front of me, so this aspect was very important to me. I am also proud of how I was able to create
arrays to store data
, because it was not something that I was previously able to do and it allowed me to create new pages with very little additional coding.
What I learned
The majority of the code in Online Composition Notebook is something that I had to learn as I was trying to create the project, so I learned a lot of new syntax creating the work. In particular, I learned how to use JavaScript to change
text styling
, how to use
JavaScript arrays
, how to allow a user to
create text
, how to use
JavaScript logical operators
, and how to create
loops in JavaScript
. I am very grateful that I was given this opportunity to learn, and I want to thank Chris A. for being there if I had a specific question.
What's next for Online Composition Notebook
As the hackathon comes to a close, I hope to continue working on Online Composition Notebook. My goal is to
create unique URLs
for each notebook so that a user will be able to open the same notebook on different devices, and to
continue to implement new features
. I want this project to remain
free and publicly available
, so that everyone can have access to free online school supplies.

10,483 | https://devpost.com/software/cool-math-game | Inspiration
As gamers, we enjoy fast-paced action-packed scenarios that will keep our mind distracted from the stress in our lives. We wanted to implement a game that requires reaction time, aim, and knowledge of math to be able to achieve great scores on it. We then created Quick Maths where you quickly answer math problems by precisely clicking choices flying across the screen.
What it does
This game educates young children on the main four operations in math, addition, subtraction, multiplication, and division. The game first asks the user the type of operation that should be questioned and the level of difficulty of the question. There are four difficulties, one being the easiest, and four being the hardest. Children best learn when the basics are shown out them first, then gradually utilize the basics to solve for more difficult questions. In our game, level one addition only asks a one-digit value plus another one-digit value that has a sum which is a one-digit value. Level two addition allows that sum to be two digits giving the user another scenario that they have to adapt to. Having Children compete to get the best scores in a game drives them to answer with speed in an interactive and fun way. Having speed will help engrave the ability to answer a certain problem in one's head, making it second nature.
How we built it
This program was made using pygame, which is a python module. It is made with object-oriented design, and each class is split into a separate file. The file with the game class runs the program. When we started off, one person made the circle clicking logic work, and the other person worked on getting addition math problems. After we made it somewhat far, We added the math problem to the circle game, with each of the circles having an answer choice. After that, the person working on math expanded on the math class, adding the four operations with different difficulty levels. The other person created a GUI for the difficulty and operation choices. He then added the logic for choosing the right answer and a timer. We then collaborated on polishing the game, with animation, sounds, and a background.
Challenges we ran into
The main challenge was figuring out how to split up work. It is pretty hard to delegate when there are two people working on one project. This is part of why we chose an object-oriented design, so it would be easier to find separate parts of the project to work on.
Accomplishments that we proud of
An accomplishment we are proud of is creating a game that will be useful to other people. Creating something that is beneficial to society with just a keyboard and a mouse is a nice accomplishment.
What we learned
Something we are learned is that object-oriented design is very useful when splitting up work. By finding parts of the program that can be separated, tasks can be made for different people
What's next for Quick Maths
This game is a good way to keep kids engaged in learning basic math, so we hope the game gets used in this practical sense in the future.

Inspiration
The classic saying, “dress for success” may not be something many of us take seriously. However, after a study concluded that dressing better caused an improvement in abstract thinking, and it was even correlated with a nearly 3x increase in salary, there might be more truth in this statement than you think. From this, we realized that learning how to dress well can have further reaching impacts than just looking and feeling your best. Thus we developed Wardrobe Wizard, a mobile application to help teach people of all ages how to “dress for success”.
What it does
At its core, Wardrobe Wizard educates users on their sense of fashion and style by allowing users to add articles of clothing and create and store outfits.
The main functionality allowed us to create an app both for users with little experience with style and fashion and also for users with ample experience. Our app’s tips and suggestions implemented throughout aid inexperienced users in creating outfits, matching colors and styles, and building a diverse wardrobe of clothing. For example, when creating a new outfit, our app suggests which clothing items will pair well together based on a machine learning model we trained with popular clothing and color combinations. Moreover, for more experienced users, the Insights page provides a comprehensive analysis of their clothing wardrobe with statistics on areas such as the color distribution of their clothes. The app aims to assist any user regardless of their experience in improving, and understanding their style.
Functionality (By Each Screen)
Item Screen -
The Items Screen shows the user all of the clothing items they have saved on the application. Users can also add more items using the “+” button. When adding a new item, the user takes a picture with the phone camera and then our TensorFlow Lite image recognition model analyzes the image, predicting the type, color, and category of the item. After they take a picture, users then see a confirmation screen where they can edit the predictions before saving the item into the SQLite database on the device.
Outfit Screen -
The Outfit Screen shows users all of the outfits they have saved on the application. Each outfit containers several items selected from the list of items saved on the app. Users can add more outfits through the “+” button, and when pressed, they are brought to a screen to select which items to add to the outfit. At this point, the app predicts and shows the user which items would pair well in an outfit using another machine learning model. After selecting which items to add to the outfit, users can name and categorize it before saving it on the device.
Insights Screen -
The Insights Screen displays a variety of statistics calculated from the clothing items and outfits the user has saved on the app. Currently, the app displays a breakdown of the color diversity of the user’s wardrobe and if necessary, curated tips to improve it. The app also has a graph of the distribution of clothing tops, bottoms, and accessories. On this screen, users can both learn to improve and diversify their wardrobe and further understand their clothing habits and preferences.
How We built it
Flutter Application
We built the app using Flutter. We first started by outlining the main functionality of the app (adding clothing items, creating outfits, and helping the user to develop their style). It was important to us that the app had an efficient, understandable user interface and impactful functionality. Once we had planned out the app, we started by creating the user interfaces and the item/outfit functionality before adding in the machine learning aspects.
Machine Learning
Machine learning is implemented in 2 areas of our application: the image detection while adding a new item and the tips and suggestions to improve the user’s style. Both models use TensorFlow Lite, based on the Image Recognition and the On-device Recommendations respectively. To train the clothing recognition model, we utilized images from the internet along with over 800 photos of clothes we took by ourselves.
Challenges We ran into
While we had some experience with app development in the past, this was our first full fledged flutter application. We had some knowledge of how to use Flutter, but we had to learn a lot as we coded. Integrating machine learning into the app was especially hard because of our lack of experience combining machine learning and flutter apps. The TensorFlow Lite image recognition model we trained was working well in our test and training cases, but once we implemented it into the app, it behaved poorly with images from the phone camera. However, after some time tweaking and adjusting both the model and our training images, the model began to work as expected.
Accomplishments that We're proud of
We are very proud of how well the app works in practice. We had high hopes when we started coding, but based on past experience, we knew it was tough to create a fully functioning app in just 48 hours. However, we believe that the app in its current state is an effective and detailed representation of what we sought out to accomplish. We were able to implement all of the core features we had planned, some of the more auxiliary features, and polish the UI.
What We learned
Throughout this hackathon, we all learned a lot about Flutter and machine learning. This was the first time any of us had attempted to add machine learning into a Flutter application, and while it was not perfect at first, we worked through the issues and figured out how to work the models.
What's next for Wardrobe Wizard
While the core functionality has all been added, we plan to continue working on Wardrobe Wizard, adding more features and improving the existing ones. Some of the ideas we have for the future are creating a new, stylized user interface, adding a shopping system for users to expand their wardrobe, and a tracking system for the outfits a user has worn recently.

Insight
Insight is a resource to help advance the understanding of COVID-19 and educate the public.
Inspiration
Since people are very concerned about the spread of COVID-19, we created Insight to educate the public by using maps and locations to inform users about essential COVID-19 statistics & information at specific places.
We also provide updated news concerning important information related to COVID-19 around the world and tips to help prevent the spread of the virus.
What it Does
Insight is a website that utilizes maps and locations to inform users about essential COVID-19 statistics & information at specific locations. We created a map that highlights information regarding COVID-19 throughout the whole USA. We also created statistics for other countries if you are interested to see the data. We even provide updated news concerning important information related to COVID-19 and tips to help prevent the spread of the virus. Lastly,we know that many people are very paranoid about their exposures with COVID-19, so we created a free quiz that can calculate how likely you are to get contracted with the virus.
How we built it
We created our website using HTML, CSS, and JavaScript.
Challenges we ran into
We had some trouble with creating the map because we had to imports lots of data and make the map look visually appealing.
What we learned
We gained a lot of experience in coding and had lots of fun!
What's next for Insight
Looking into the future, we foresee that our platform will be fully functionable and attracting many users within 8 months. In the next month, we plan to continue to develop our platform by improving the front end looks and back end security & functionality and to make a mobile application. Second, we plan on spending about 2 months to get feedback on our prototype and adjust our product accordingly. Once finished, we can launch the product to the general public. The last and longest step, taking 4 and a half months will be our marketing campaign, in which we will expand our user base. We will do this through two major channels: social media influence and spread of information through word-of-mouth. This is our plan of strategy for Insight.

Inspiration
Have you ever walked past a monument or landmark site, wondering what it is and why it was built? Many questions pop into our heads, leaving us with a longing for more information.
Furthermore, the COVID-19 pandemic has completely shattered the world, and the travel industry especially has been one of the hardest hit, with people not being able to travel, whether it’s for seeing family or personal growth and enrichment or discovering new cultures. Many people can no longer afford expensive tour guides in this time of economic hardship, not to mention the transmission risk of the virus.
When brainstorming, we were very clear that we wanted to create an app that would be most useful to people in real life, given the current circumstances. We believe that machine learning can be used to educate people about the important historical sites they visit and provide them with a simple interface to make travelling more informative and safe, as it requires no person-to-person contact, compared to large clusters of people travelling with a tour guide.
What it does
Landmark is a mobile application that uses camera vision to instantly recognize monuments and historic landmarks you have either taken or uploaded a picture of, and finds relevant and detailed information about it with external links, in the form of an easy-to-read flash card. The user can take the picture in real time at the site, as well as upload any previously taken picture, which is an especially common scenario and use case, as people often yearn to recount information or learn more about a site they visited in the past.
Landmark also provides a maps page, which seamlessly integrates with google maps features, and instantly finds the nearby monuments and historical sites that the user can visit, as well as information about these sites.
How We built it
React-Native for mobile app front-end
Flask for back-end and database + API integrations
MongoDB Atlas for storing user data.
Google Cloud Vision for camera vision model.
Tensorflow.js for another image classification model (we didn’t use this in our end product as Google cloud vision performed with higher accuracy)
Wikipedia API for getting flash card data.
Google places API for finding nearby sites
Figma for prototyping and UI design
Heroku to host back-end endpoints.
Challenges We ran into
The major challenge we faced was integrating react native with google cloud vision. Encoding the image into base64 was a major challenge, which took us nearly 2 hours to get over. The other challenge we faced was getting the wikipedia APIs to work properly.
Accomplishments that We're proud of
We are proud of creating a novel app that actually works at production quality. We are proud of integrating google cloud vision APIs, as well as google places, and wikipedia APIs. We are also proud of creating a responsive and clean UI, as we are relatively inexperienced in React Native.
What We learned
We learnt how to use the Google Cloud Vision API, Google Places API, Wikipedia APIs, MongoDB Atlas, and react native, given it was the first time our we had used react native in a real project.
What's next for Landmark
We want to make a more sophisticated system for getting the image for a monument. We would like to migrate our back-end to NodeJS for robustness and scalability, as well as host it via AWS or Azure, instead of Heroku. We would like to make the app more friendly to Android and older IOS versions. Lastly, we also want to solve any minor bugs and release this app on the app store and google play store.

10,483 | https://devpost.com/software/clickbait-activism-rqlo27 | Inspiration
I was inspired by the many events and movements currently occurring in today's society, such as the Black Lives Matter movement. I have encountered racism, thus I could all deeply empathize with victims of various crimes. However, I realized that some people cannot/do not empathize with victims. I wanted to help those people see from a different perspective and change their way of thinking, re-educating them and dispelling any misconceptions about various movements. I also wanted people to be incentivized and even excited to learn about activism, hence the games, quiz, and points.
How I built it
With me having a beginner level of coding, I decided that a simple website with HTML, CSS and JavaScript was ideal for our solution. Despite being a beginner, I coded the entire solution from scratch, so there was naturally a huge learning curve, especially as this was created in the span of two days. HTML, CSS and JS allowed me to easily create an attractive, usable interface, whilst also being able to keep track of the functionality of different aspects of code using different external CSS and JS files.
Challenges I ran into
As I was a beginner, I naturally faced many challenges. It was difficult to work on a new platform which was Glitch. Since, I didn't have much coding experience in the past at all. Despite that I pushed through and learned many new things from the workshops and searching things up on my own.
Accomplishments that I am proud of
I am very proud of the home page, as that is one of the main features to attract those with unjust behaviours. Additionally, I am very proud of the points system in place, as there were a lot of complications trying to pass variables between different files.
What I learned
I learned many HTML and CSS techniques, such as styling photos between text on the homepage and the tags, as well as how to pass variables between different files in JavaScript. I learned more applications of JavaScript, especially for the games and point system.
What's next for clickbait-activism
There are many things I could add to clickbait activism. One feature would be to add a pop-up video on the homepage, to directly confront the user. I would add a login feature for users to save their points and map their progress to have a more gamified approach that would further incentivize people to stay educated and up to date. People who share our link would also get points. In the future, I would also start social media accounts that would use the same clickbait strategy. I would have better prizes that would be more appealing to inspire users to keep learning, maybe with the help of sponsors.

Inspiration
TimeBox was inspired by the productivity technique known as Timeboxing. Timeboxing gives a person a visual representation of the time they have to do certain things throughout their day, creating a more productive day overall. It was made to deal with the issues of time management when taking online school.
What it does
It is a minimalistic application that allows the user to write out all the things they have to do, and put them on a timed schedule. This allows the user to fully visualize their necessary tasks and plan out a productive day.
How I built it
I used a text editor called Glitch.com. The editor has a simple node.js app template that I built my project upon.
Challenges I ran into
One major challenge was the html table. It was hard to figure out how to set it up where the cells could be edited by the user. Another one was using node. I'm newto javascript, so I had to learn how to use it properly for this web app.
Accomplishments that I'm proud of
I am proud of the site's responsiveness and simplistic UI. I often find myself putting too much into a project, so it was nice to create one that was as condensed as this one.
What I learned
I am not very experienced in javascript, so this project allowed for me to build up my skills in the language.
What's next for TimeBox?
The application, currently, is very minimalistic, so the next step would be to add more features that help the user become even more productive.

We would like to make it easier for hackers to finish these amazing projects without explaining how to get HarmonyOne. Allowing our friends and family to use their traditional payment method of a credit card to help with the funding of the project. Essentially we created a fiat gateway using traditional credit card payments.
What it does
We allow a project owner to create a landing page with a goal for their project. The end users can see the harmony one wallet that needs to be funded to send either Harmony one or use a credit card via Circle to help the project reach its goal.
How we built it
We used circle to fund a usdc wallet with our own backend API calls allowing us to use a pool of Harmony be moved from our wallet to the project wallet. We essetually is prefunding the harmony project while getting USDC and a % for holding the Harmony until the project is completely funded.
Challenges we ran into
We were not able to find a reliable cost effective bridge from USDC to Harmony. So we built a centralized solution until we are able to overcome this issue later.
Accomplishments that we're proud of
It Works! LOL We attempted so many things this month trying to get certain things to work and failed. So we were estatic to see this funding mechanism working in the test environment.
What we learned
We need more time to learn the platform and its capabilities.

Inspiration
Our main goal is to build cross-chain lending. So first we have to build a protocol or a bridge between chains to be able to exchange crypto. GoldenStar swap is a demo for this main product, the first two chains we aim to be Ethereum and Harmony because they have some common point such as the smart contract building language (Solidity) as well as the use of Oracle Chainlink are available on Harmony and Ethereum.
What it does
GoldenStar swap allows you to convert between Erc-20s, ETH on Eth to One (native token in harmony). Thanks to Chainlink Oracle, we can optimize the exchange value between two tokens to help you have the most profitable cost. You can convert any type of ERC-20s to One, otherwise we have perfected the core but haven't really built the interface yet, but it will be finalized soon.
How I built it
Goldenstar is built on three main modules including EthBridge, HmyBridge and Relayer. In which the pricing of exchange tokens used through Oracle Chainlink is on Ethereum and Harmony.
EthBridge: Lock the amount of tokens exchanged into the contract and calculate the value of the locked token at that time through Oracle Chainlink, emit Event Lock token for Relayer
Relayer: Subcription EthBridge to receive Event Lock and moderate them before transferring to HmyBridge
HmyBridge: Receive events from Relayer and parse the data, calculate the corresponding number of One through Oracle Chainlink located on Harmony and transfer amount One accordingly.
Inspired by the open source
https://github.com/harmony-one/ethhmy-bridge
, we have built a swapable POC from ETH, erc20 to One.

Challenges I ran into
To combine different blockchains, there are always difficulties, especially operational problems. In addition, the use case of the exchange between tokens requires updating the price between the two parties quickly enough to avoid detrimental to users.
Chainlink Oracle on Harmony side is quite simple but we were able to run a complete version on their testnet.
The challenges we will face will still lie ahead when incorporating more blockchains, establishing validates between relays (consensus), establishing liquidity pools between blockchains.
Accomplishments that I'm proud of
All the team members tried their best to come up with a product that could compete in a short time. Although the project is just a small use case in the product that we are researching and building, we have worked together to build a complete demo.
What I learned
After completing this project, the entire team has clearly improved their skills in writing smart contracts, interacting with Oracle Chainlink as well as skills in building frontend.
What's next for GoldenStarSwap
As mentioned above the goldenstar swap is a demo of the product we are looking to build: Lending cross-chain. We are continuing to build bridges between blockchains.
In the next versions we will incorporate additional blockchains:
Tomochain (with native token Tomo)
Cosmos hub (with native token Atom)
Build up an interface for the user to provide liquidity to receive farming tokens.

Conclusion and Future Improvement
Inspiration
I want to build an application which gives power to individuals to request resources provided by charities like Food Bank or non-profit organizations. Meanwhile, those charities could manage their resources, including donations and volunteers, using the application. As a volunteer, donor, or low-income worker, I wish I can trade my kindness for something whenever and wherever I need them, e.g, an online course, a piece of craftwork, instead of feeling guilty. Furthermore, I wish my kindness could be traced and acknowledged by society.
This project is a prototype inspired by this thought.
What it does
A user can request tokens from a fund through the application built in the project. Meanwhile, the user is able to make a promise to donate token in the future. The user should redeem such a promise later.
How I built it
The project contains two kinds of smart contracts, one is used by a user (e.g, a donor or fund consumer), and another one by an organization.
The smart contracts are implemented with solidity. The user smart contract is called PayItForwardWallet, and it contains the interface for a user to consume tokens from a fund, donate tokens to a fund, consume with promise, redeem promise, or withdraw tokens. The organization smart contract is called PayItForwardFund, contains the interface which responds the request from PayItForwardWallet to consume/donate tokens.
The demo app contains a nodejs backend. The backend realizes RESTful APIs by calling the interfaces of smart contracts through Harmony-one sdk. The front end is a Vue app.
Challenges I ran into
I took some time on learning solidity, and got some help on using harmony-one-sdk.
Accomplishments that I'm proud of
I am proud that I have built a DApp on blockchain finally.
What I learned
I learned that it is not that difficult to build a DApp, also, compared to a classic mechanism, payment or money transfer mechanism using blockchain technology does have its advantage: these functions could be achieved without considering the security boundaries of different organizations.
What's next for Pay It Forward
We hope that the app could trace the transactions which consume token requests or redeem promise. In this way, different transactions could chained together, and the effect of kindness could be seen.
Also, we could have a better UI. The smart contract for users or organizations could be future improved.
In the demo, the front end calls backend to read from and write to the harmonyOne platform. We are going to make frontend calling harmonyOne platform using its SDK directly instead.
The smart contracts of this projects are deployed on the testnet as demo. We also want to deploy production contracts on mainnet for a non-profit organization.

10,484 | https://devpost.com/software/shofar | Olifant
Inspiration
Inspired by crowdfunding apps such as Kickstarter and Indiegogo, we have built a crowdfunding app, Olifant, with Blockchain Harmony technology, which allows investors to directly donate cryptocurrency to crowdsoured projects. Olifant is built for mobile devices and currently supports ONE as its main currency.
The simplicity of donating via an in-app wallet makes Olifant highly accessible for all potential investors while the fact that it is completely free makes the app irresistible for all potential crowdsourcers. Yes, unlike many other crowdfunding apps, we do not charge a 5% fee per donation. Olifant is built with Smart Contracts and serverless solutions, which allow it to operate without users' monetary contributions.
So, take a deep breath, pick up this Olifant, and make your project known to the world!
What it does
Olifant is a crowdfunding app for mobile devices.
There are 2 groups of users for Olifant: investors and crowdsourcers.
The shared features for these 2 groups include:
Built-in account management. We can both import the data from an external source and use in-app data.
Browse currently active crowdsourcing projects.
Investors:
Donate to projects of choice using native token ONE
Monitors projects that they have invested in
Get their money back in case the crowdfunding campaign is unsuccessful
Crowdsourcers:
Introduce, describe and update their projects
Receive money if the crowdfunding campaign is successful.
How we built it
We built Olifant with 2 main components: Smart contract written by Solidity and deployed to mainnet, and Interface written by Flutter.
Smart Contract: There are 2 main parts for Smart Contract: Factory and Campaign. Each project is an instance of Campaign while the management of each crowdsoure campaign is handled by Factory contract. All financial data is processed via these Contracts.contract campaign is responsible for managing all the logic of the crowdfunding campaign. The Crowdsourcers can only withdraw money from the smart contract when all conditions are met. Investors can also withdraw their money when the fundraising campaign fails.
Flutter: We interact with Smart Contracts via JS-wrapper functions. We store project updates and comments by users in Firebase Firestore.
Challenges we ran into
The initial challenge we ran into was how to use Flutter/Dart to interact with Smart Contract. Comprehensive libraries were not readily available, forcing us to write our own in order to interact with Harmony as well as the Smart Contracts deployed there. Our current solution is to use Javascript wrapper in Dart. There are a lot of platform issues which make writing testable code very difficult. Therefore, we are developing a library to interact with Harmony in pure Dart to solve more complex problems.
Accomplishments that we are proud of
We are proud of overcoming the very challenges that we face when choosing to build Olifant for mobile platforms. Right now we can use JS wrappers like native functions in the app. We had the change to dig deep into SDK provided by Harmony and are writing a Harmony SDK for Flutter/Dart. We are hopeful to complete this library and publish it as an open-source soon.
What we learned
How to run an effective team remotely was the first thing that we learnt doing this project. Even though the entire team was working from home, we have coordinated with each other well enough to make Olifant work.
What's next for Olifant?
In the next versions we will try to improve user experience, publish the apps on AppStore and Google Play and, if possible, build a web-based version of Olifant.
Currently all financial data is processed on Harmony while operation data such as project updates and comments are stored on Firebase. We will move all operation data to Harmony so that Olifant can operate without any fee. We are adding other tokens besides ONE to our list of supported cryptocurrencies.
After improving user experience to a certain level, we hope that there will be Defi apps similar to Balancer, Curve, or Uniswap like Ethereum on Harmony. Then, Olifant can provide liquidity to these apps at a reasonable interest with the money from running crowdsourcing campaigns, helping crowdsourcers speed up their campaigns and quickly achieve their funding goals.

KOH Dashboard #1
KOH Voucher Payment #1
KOH Voucher Payment #2
Inspiration
Many small shop and street vendor in Indonesia sell what we called
Voucher Data
. It is a voucher for digital product like airtime or game item. It is unique, it can be bought but it can not be sold back to money. It still possible to be sold back to money in black market but the price will drop > 30%. This happen because voucher provider still dominated by big company, telco and they take big cut to redeem the voucher.
To solve above problem we make a token with some features called Voucher IDR (VIDR).
But, just a product is not enough, we must have the product used by the vendor and end user. We must have the market to adopt it. We need support. Support for blockchain development can be by donation, grant or ICO (initial coin offering). The latter got bad name, because price performance not meet expectation.
To solve above problem we make a dapp called Kings of Harmony (KOH). Inspired by King of Ether, we make a scheme to give support for development. Supporter will receive token with limited risk and fixed price performance.
What it does
Voucher IDR (VIDR)
is a voucher for digital product in Indonesia. It is HRC20 token based on stablecoin RUPE in harmony blockchain. It have some additional functions:
Generate voucher. Anyone can generate/mined voucher as long he have RUPE and ONE for gas fee. Street vendor and small shop now have another voucher as alternative.
Redeem voucher. Now any merchant or startup can accept voucher payment easily and redeem it back to stablecoin RUPE. The difference in price is very small (3% vs >30%) in RUPE (exclude gas fee).
Sponsored payment. A transaction in blockchain is complicated for end user. User must have native coin to pay for gas. Inspired by EIP 865, we make this function that can be called without gas. User just need to sign, and sent the signature to merchant. Merchant will pay for gas.
Price difference in RUPE to generate and redeem voucher will be sent to Kings of Harmony Pool. Sponsored payment also generate fee in RUPE that sent to pool.
Kings of Harmony Share (KOH)
is a scheme to help VIDR development and market adoption. It is a smart contract or pool that accept fee in RUPE from VIDR. It also a HRC20 token. KOH token represent percentage to assets locked in pool.
Beside standart HRC20 token functions there are three additional functions:
Update price. KOH price is in ONE and calculated by:
total assets ONE & RUPE locked in pool divide by total supply of KOH
Its mean: if ONE & RUPE locked in pool increase, the price of token KOH will increase. ONE locked will increase if there is event buy token. RUPE locked will increase if VIDR smart contract sent fee. This function always called after buy/sell token, and can be called directly anytime.
Buy token. A percentage in pool can be bough by anyone, anytime, in any amount, but in 130% current price. Which 15% will be for development, 115% to be locked. It is inspired by king of ether, which the next king must pay for previous king. By have 115% ONE locked, its mean 15% will be used to increase value for token. Benefited previous token holder or kings!
Sell token. KOH token holder can leave the project anytime. He can sell his token and receive back ONE in 100% current price + bonus stablecoin RUPE, part of VIDR fee. Remember current price always higher than previous price, the return greater for long term holder.
How I built it
I write the smart contract following openzeppelin standart, truffle, and harmony sdk example. Deploy it on testnet and later in mainnet. To interact with mainnet, i made a dapp in reactjs that connected directly to harmony blockchain (no backend). The dapp can be used to generate/redeem voucher and join/leave kings of harmony scheme. The dapp deployed to netlify at
https://kohdashboard.netlify.app
.
A second webapp has been built to demonstrate payment without gas. It is a demo of voucher payment. User must pay by voucher VIDR to buy but no need to have ONE for gas. It is built on reactjs & harmonyjs and deployed to netlify at
https://kohclientdemo.netlify.app
. To support gasless payment a rest api has been built and deployed to heroku at
https://arcane-plateau-67130.herokuapp.com/check
.
Challenges I ran into
Gas. Gas used to run methods in smart contract should be calculated easily. EstimatedGas function sometimes return value that make transaction success but not change blockchain state. For now, i set value for gas to fixed big value.
If some error happen in smart contract, there isnt any error message, so its difficult to debug.
There is no decentralized exchange deployed, so i can not convert RUPE to ONE. For now, asset locked in pool are ONE and RUPE. Ideally there is only ONE.
Accomplishments that I'm proud of
This idea is how cross border investment can be modeled. How crypto communities (ONE holder) invest on product backed by stable coin (RUPE). Its can be called community owned stable coin, because the fee to make payment, mine & burn used to pay back to community on chain.
There are many components to built: 2 smart contract in solidity, 2 dapp to interact with smart contract (Voucher Generator & Kings of Harmony), a rest api + a front end (Voucher Payment Demo) to demonstrate gasless payment. Luckily i can built them on time.
A Gasless smart contract function. This function needed extra security. A function cannot be replayed, and must ensure the signature valid. This is complicated but it can be done!
What I learned
Harmony JS, javascript library to interact with smart contract in harmony blockchain.
Harmony ecosystem, wallet, etc.
Gasless Function based on EIP 865.
Openzeppelin Standart Contract
What's next for King's Coin
This submit, is a proof of concept. A product to help small business and startup in Indonesia to receive voucher payment. Our startup planned to built some app to support its growth:
If uniswap-like deployed in harmony, the pool should be accept single asset.
Create client SDK for VIDR, so any startup in Indonesia can have his own voucher payment gateway.
Have any voucher seller in Indonesia to know and sell voucher using this dapp.
Have many online seller/startup/small business to integrate VIDR.
Improve voucher payment demo to full user wallet & have many user to install them.

Creating an initial loan with a set of rotating Harmony addresses
View the executed transaction on the harmony blockchain
Testing
Used remix to test and validate contract on the test network.
Recycloan
Microlending for disadvantaged entrepreneurs without access to credit.
Inspiration
More than 1.7 billion people around the world are unbanked and can’t access the financial services they need. Recycloan aims to address this by allowing charitable lenders with tools to get resources to those that need them the most and maximize the impact of a loan by automatically relending funds once they are repaid. With crowd sourced micro-loans, students can pay for tuition, women can start businesses, farmers are able to invest in equipment and families can afford needed emergency care. With all transactions taking place on the blockchain, lenders benefit from increased accountability and borrowers can establish credit.
What it does
Recycloan allows anyone with a Harmony wallet initiate a new loan. The lender selects one or more address of borrowers they wish to lend to and the amount they would like to lend. The funds are immediately transferred to the first account on the list and once repaid, they are transferred to the next until the end of the list is reached at which time the funds are returned to the lender. At any time the lender can add additional borrowers to the end of the list.
Anyone can query a list of borrower addresses as well as the number that have repaid a loan providing borrowers with records of their loan transactions.
How we built it
Recycloan comprises a smart contract on the Harmony mainnet and a web application. The web application is built using React.js and the smart contract is built using Solidity. A loan can be initiated on the Recycloan smart contract using the lend function, which establishes a list of borrowers and funds the balance of the contract. The balance is immediately transferred to the first borrower. The repay function allows a borrower to repay the funds they were lent, and once the balance reaches the full amount lent, it is transferred to the next borrower.
We used the harmony-core and associated harmony javascript sdk's to facilitate the contract interaction from the Recycloan web UI.
Structure
`application`: Client (website) for logging into a harmony wallet and sending a transaction (uses preset mainnet contract address set in `harmony.js`). This project allows lending via the `lend` method of the `Recycloan` smart contract. Interacts using the harmony sdk.
`contract`: Truffle migrations and Recycloan harmony smart contract.
Accomplishments that we're proud of
We were successfully able to deploy a smart contract on the Harmony mainnet and interact with it through out web application using our own Harmony accounts.
Recycloan deployed smart contract address
mainnet0: 0xF498DaBf26fC52F727F996C4116e444bC6778452
testnet: 0xf12e5348250772A3A7b05DBF7827a0323f296ab9
What's next for Recycloan
Next we plan to build a web application for borrowers to interact with our smart contracts to access their transaction records for the purpose of establishing credit history based off a wallet address. The smart contract already includes a means of accessing this information so we simply need to create a UI for querying the records.

10,484 | https://devpost.com/software/cryptopet | Cashback - We pay more than cash back
Buy flow
Withdraw interest flow
Landing page
Payback after purchasing
Inspiration
Defi flourishes on the Ethereum platform, but it comes with limitations that eth has not been able to overcome: transaction validation time and transaction fees are too high. The peak times of transaction costs on Uniswap went up to $ 50 just to transfer $ 10. Harmony has improved on those two and could be the perfect place for building Defi applications. Therefore we want to build a new Defi application on Harmony platform with a completely new concept inheriting the idea of lending and borrowing.
What it does
Cashback is an e-commerce platform that allows users to purchase items for a refund in the form of HRC20. Each product will have a corresponding refund rate. After being reimbursed in HRC20 form, users can staking that amount of HRC20 to be able to Yield Farming to generate a corresponding ONE, after each day 2% of the HRC20 is converted to ONE. Therefore it will stimulate the user to buy so that it can increase the rate of pay normally. Users can withdraw the converted ONE at any time they want, however when withdrawing the HRC20 amount will be burned corresponding to the percentage of ONE withdrawn. This will stimulate users to staking the HRC20 amount to be rewarded with more ONE.

Show purchased products:
Interest will be increased daily based on the amount of Sun coin you hold:
You can withdraw the interest at any time but the sun coin will be burned:
How I built it
Cashback is built on 2 smart contracts, Market and Point. Market is used to coordinate activities on exchanges such as buying, selling, withdrawing money, ... Contract Point is a temporarily customized ERC20 contract that cannot be transferred between accounts, but will only play the role is staking and to calculate the amount of daily ONE that a user will be paid for by staking.
On the client side, we use vuejs to build, combined with harmony-sdk to help users interact with the application through MathWallet.Users buy and sell as well as keep Erc20 cash back through mathWallet
Challenges I ran into
The first is the construction of smart contracts, unlike eth, we can test directly on remixes, to build contracts on harmony we mostly use unit tests to be able to audit our contracts. In addition, the way to interact with the extension wallet is not really perfect.
Accomplishments that I'm proud of
What makes us proud is our idea, although it is inherited from Defi lending, it has not been applied on any real product. If this idea is deployed we think it will have great applicability.
To solve the problem of user compensation, we are also building a cross-chain using cosmos to switch between native tokens, which could open up new doors for the Cashback:
Products can be purchased on the app with many different tokens
The exchange fee between the tokens will be used to pay for the staking HRC20 cash back on the Cashback e-commerce platform as well as for the liquidity providers for the cross-chain bridge.
What I learned
We learned how to come up with an idea together and step-by-step completed it. Learn how to divide your work properly. On the technical side, we learned more about a blockchain platform - Harmony, how to build smart contracts and interact with them.We learned how to deal with moving parts and stay on top of constantly changing dependencies and protocols
What's next for Cashback
First, as mentioned above, we are building a cross-chain protocol with cosmos, however the hackathon time is limited so it is not enough time to submit this product - this product will be like a the bridge between Harmony and ETH - from which users can buy and sell products on the Cashback floor with existing tokens.
Next we want to make Cashback a marketplace where people can sell their products at their own rates of return (the competition benefits the buyers). Successful transactions will be charged and this fee will be used to pay bonuses to those who are staking HRC20 cash back when buying items.

0Games.io
0Games is a peer-to-peer 0% fee CD Keys crypto-marketplace. You probably heard of G2A.com or Gamivo.com, these are CD Keys marketplaces where sellers can sell Steam CD Keys. These platforms are very popular with millions of visitors per month. However they take up to 30% fee! 0Games is here to lower that fee to zero.
I started working on 0Games a few months ago for the PayId hackathon and
won the second place for my integration of PayId with 0Games
on the ripple Testnet. I am now submitting 0Games Evolution, the next evolution of the platform which integrates with the Harmony Mainnet.
To use 0Games, start by registering an account. You will need to enter an Harmony One Address. This will create a PayID account for you at wallet.0games.io associated with your address. Now choose a game on sale, for instance the Random Steam Key and you will see the list of sellers. Notice their respective PayIDs. Click buy. You can see the details of the transaction to make. Notice that this is a direct payment from you to the seller, the transaction does not even go through zero games, guaranteeing that no fee is taken. However 0Games is able to track the transactions history of the seller, providing the buyer with the key only if the transaction is successful. Let's go ahead and open the Harmony wallet and complete the payment.
Now, back on 0games, click "Check transaction status". If your transaction was successful, you will immediately receive your Steam Key. As stated earlier, 0Games Evolution is deployed on the Harmony main net, meaning every purchase is for real and the keys are actual Steam Keys. Open Steam and go to "Activate a product on Steam". Enter the key and you should now be able to download and install the game.
Finally, if you have keys you want to sell, click Sell you key, and enter your key and a price. You key will now be listed for sell.
0games is fully functional but there are still many features to be develop such as leaving a review on the seller after a purchase to prevent scams, or doing a KYC of the sellers to prevent money laundering. With your help, I hope to make 0Games the next G2A or Gamivo!

About Blinkit
Blinkit goals are to notify you with light and sound when blockchain action are detected. The supported devices that can be blinked are widely available and preferable inexpensive. The project is opensource and there is a big chance you already have a supported device at home that you can upcycle and give a crypto purpose with the use of Blinkit!
Blinkit is available for multiple blockchains and started in 2018, each version has functions specifically developed for that blockchain. The development of Blinkit comes forward out of the passion for devices, blockchains, technology and to make them interact and connect.
Blinkit v4.0 For Harmony
With Blinkit for Harmony you can get notified of new ONE transfers to your or someone's wallet, set price alert notifications to get reminded to trade at specific ONE price points, and other functions that can help you to get notified to interact with the Harmony blockchain, it's users, dapps, exchanges and other projects that interact with Harmony.
Functions:
Blinkit v4.0 for Harmony have the following functions:
Blink on ONE wallet balance changes, use it in combination with exchanges, dapps, or any transaction or wallet.
Blink on ONE price changes, when the ONE price goes up / down do a blink and sound action for the selected device.
Blink on ONE price alerts, (above or below a set price alert) reminds you with sound and light to buy or sell ONE when a specific price point is reached.
Blink on node status offline, when the set node is offline blink the selected device, when online stop blinking.
Blink on epoch, when the epoch time is finished the selected device will blink.
Settings
Wallet address, set your or any wallet address that you want to use and get notified about.
USB drive, if you selected "USB drive" as device, you can set it here to your USB drive letter.
Device IP, if you selected Smarthome devices, you can use this setting to set the IP address of the smart home device.
Light blink length, change this number to make the light blink longer or shorter.
ONE price alert, change this to the price you want to get notified on when it reaches this price point.
Harmony Node, optionally the Harmony node that Blinkit uses to connect with the Harmony blockchain can be changed. On the Blinkit website are some alternative nodes listed on a world map that can be used.
Supported devices:
USB flash drives
Any USB flash drive that have a status LED, independent of its brand or model can be used, most preferable will be a USB stick with a bright LED and a small form factor.
Keyboard lights
Most keyboards and laptops have a num, scroll, and caps lock LED status lights, Blinkit can blink them when blockchain actions are detected independent of brand and model.
Smarthome devices (Tasmota)
Over 2000 inexpensive devices like wireless lightbulbs, power switches, LED strips and even RGB lightbulbs can be used to blink on and off when newly detected Harmony blockchain actions are detected. (Supported smarthome devices must run the popular opensource Tasmota firmware.
A list of compatible smart home devices can be found here:
https://templates.blakadder.com/all.html
)
How is it build?
Blinkit is made with a combination of batch scripts for the back-end and HTML and CSS in a HTA application for the front-end. It's opensource and this approach ensures that all files can be edited without being depended on a SDK or 3rd party software or being compiled. Just a simple text editor is enough to start tweaking it, all code is commented, share your tweaks in the Blinkit Discord chat, so they can be reviewed and implemented.
Blinkit uses the Harmony API to get the latest data from the Harmony blockchain, the used documentation:
https://api.hmny.io/
The default API node is set to:
https://api.s0.t.hmny.io
Latest ONE price data is coming from the Coingecko API:
https://www.coingecko.com/en/api
What's next for Blinkit
More devices will be made compatible, and more functions will be added and beside that, Harmony branded USB flash drive prototypes are in development to explore the possibilities with a dedicated branded device, besides this prototype other options, solutions, and devices are explored and considered as well.
If Blinkit wins one of the Harmony Hackathon prices, It could very well be that there will be a giveaway where you can win a Harmony branded, Blinkit compatible prototype device, depending on several factors it can even result in a mass produced Harmony device, and a multiplatform version of Blinkit.

Inspired by kids saving money, the tokens will also be saved and kept by a virtual pet. At first, the dapp only stops saving money on pets, later on these savings can be used to invest in financial investment funds.
What it does
Users can save their money by adopting, raising pets (through buying food for a pet by ONE). There are two points you need to remember if you want your pets to grow perfectly: feed duration and pet balance. Feed duration is a measure to detect the shape of your pets while the remaining balance of pet determines the size of the pet.Feed duration will be increased if your pets are fed regularly. Last but not least, You can still withdraw your money in pet whenever you need.
How I built it
We came up with the idea of building a virtual pet dapp combined with savings
Contracts : Written by solidity, deployed by truffle framework
Frontend : Reactjs framework, canvas with createjs, integrate with Harmony through harmony-js
Challenges I ran into
We need to spend a lot of time collecting, design sprites for pet. Building game in blockchain quite different with casual games
Learn to be familiar with the Harmony's sdk, how to interact with the math wallet, one wallet
Accomplishments that I'm proud of
We have built a product that can run stably on the testnet of the platform. Building a foundation application so that in the future it can be easily integrated with new features such as saving with many different tokens
What I learned
How to build complete dapp on harmony basis
Working with Harmony wallets
What's next for Ecopet
Integrate with many types of tokens so users can pet with tokens available in the wallet, those tokens can be redeemed for ONE
Trading and exchange platform for pets
Each pet will become an investment.So, ecopet will become a platform connecting small investors with financial funds.

10,486 | https://devpost.com/software/how-mosquitoes-might-be-controlled | The first home buyer scheme for mosquitoes!!!
This proposal aim to stop the mosquito breeding through disrupting their life cycle. We provide mosquitoes with habitats or mini- ponds to safely lay eggs.
This man made places will be an environmental friendly metal pot or terracotta pot, mouth covered with a 2mm net filled with water. This gives a good opportunity for mosquitoes to lay eggs. After they lay eggs it will grow in our man made environment stage by stage Larva, Pupa and it will try to complete the cycle and leave as a full grown mosquito with size 4-8mm long but it will trap them inside man made environment.
We need to keep this types of pots around university buildings, open area (picnic areas),pathways , bus stops, car parks and surrounding bush areas.
The optimum places will be above ground level, around the buildings. Twenty pots per a floor area of 1000m2 building would be ideal.
In the open areas (bus stops, car parks, pathways, etc.) safely placed below ground level pots or above ground level pots (maybe decorated pots to provide an aesthetic value) hanging 1.5m above ground level from trees would be ideal.
Items required
Pots 10000 (Without holes in the bottom)
2 mm net 900m2
Cable tight 10000
Garden Spade 50
How to do
Ask university students, staff and their families to sign up for this worthy cause happening at the UON Community Garden on one of the Saturday or a Sunday morning and group them into 10 member team with a team leader. Each team would be given instruction and area to complete the job with pots. University will provide meals through Unifood with a mobile food truck. If possible, Uni will pay each participants $100 irrespective of their age for the worthy cause. This will be a family fun day with exercise and problem solving.
Costs involved;
Item Cost
Pots $2*10000
2-3mm nets $5000
Cable tight $1000
Garden Spade $2000
Total cost will be around $45,000 including products, manpower and refreshments

10,486 | https://devpost.com/software/wear-pellents | Idea Name: wear-pellents
Participants Full Name: Kudzai Chikondo Beta
Mosquitos have an irritating bite and sound very annoying. Some current repellents are applied directly to the skin. Which opens the possibility of skin irritation and might pose as an asthma risk for various individuals. Another available option is mosquito repellent clothing. However, this too can result in skin irritation and primarily it limits an individual’s fashion choice. These current repellents eventually wear off, with the DEET sprays wearing faster when you sweat heavily and become redundant after it rains or when you take a shower. From initial research, mosquitoes were discovered to have a smelling distance of approximately 30m and their sight is approximately 4-6m.
The proposed solution for this is the use of wearable repellents like bracelets, necklaces, arm-bands, key chains, clip-on’s on bag or clothes, etc. These wearable repellents (wear-pellents) in the form of bracelets, will be implanted with replaceable repellent in the form of pellets or some form of matter that will secrete a scent that repels mosquitoes in the same way some plants repel mosquitoes. This will hopefully create a virtual bubble around the individual wearing the device, serving to musk the individual or drive the mosquitoes away before they can notice the individual. This proposed solution provides flexibility to the end-user when going about day to day activities, when going to sleep and gives the user free fashion choices. Repellent pellets will hopefully be plant-based (but a sustainable environmentally friendly chemical alternative is acceptable), and in combination with the wearables being able to be used repeatedly will aid in reducing the environmental impact. With basic designing procedures utilising thermodynamic, fluid mechanic, dispersion and repellent analysis, this can be the reality in the near future.
This product can be utilised all across the world. This will create sufficient demand for this product hence the cost of the product will be fairly low. Ensuring that even the poorest of communities can afford the product. The product being able to be reused limits the amount of waste produced by current methods. | wear-pellents | wearable repellents | ['Kudzai Beta'] | ['School Locker Voucher'] | [] | 2 |
10,486 | https://devpost.com/software/a-green-solution-to-mosquitoes | My idea for minimising mosquitoes on campus, is a simple solution. It involves upgrading our native gardens around the high pedestrian traffic zones around campus with more "mosquitoe repellent" plants that are native in Australia and New South Wales. Some of these plants include: Citronella, Lemon grass and Leptospermum species, and gardens should be improved to have higher clusters of these plants to improve their efficiency for blocking mossies. In turn with students and staff social distancing to keep clusters of people from being in the same area, could have a positive relationship with the plants repelling the mosquitoes.
Upgrading these gardens will also have a positive influence on students and encourage them to be outside on campus and use of social areas. This solution will also be highly cost effective, as the university have labour in place for horticulture and maintenance, as well as these plants being highly robust and low maintenance. An overhaul of our native gardens will also make the campus a greener, more eco-friendly, and pleasent for the senses, increasing everyones experience.
Challenges that are regarding this solution is the time interval for progress and is not garunteed. Using these plants to our advantage wont be an overnight solution but rather a lengthy process that will most likely be season. However, these challenges are easily overcome with the right knowledge and experience.
This solution is easy, environmentally safe, and could be a good community project for students to get involved with.

10,486 | https://devpost.com/software/repel-in-style | Mosquito patch can be bought in stores to repel mosquitoes, but it is disposed after single use. How about making and wearing your own reusable mosquitos-repelling accessories such as bracelet and necklace? Protect yourself from irritating mosquito bites (and possible illness) by deterring mosquitos with easy-to-make, effective DIY mosquito repellent bracelets and necklaces.
Essential Oil Mosquito Repellent
Ingredients for the essential oil mosquito repellent includes 9 drops of purification, 4 drops of peppermint, 4 drops of citronella and 3-4 tablespoons of carrier oil (almond or olive oil)
Garlic Mosquito Repellent
If you do not have essential oils, you can make a less pleasant-smelling concoction (still quite effective) from garlic cloves. Cut the garlic and put it in some water. Let it ferment for a day at room temperature. Then store your mix in the fridge.
Make Bracelet and Necklace
Braid strips of fabric together to make a fabric bracelet or necklace. Start by securing the ends of your bracelet together with a piece of string tied tightly or a small rubber band. To use your mosquito-repelling bracelets or necklace, put them on and add a couple of drops of oil (or the garlic mixture). The scent of the oils will help deter the mosquitoes and you will be less prone to mosquito bites.
In time, after repeated use, the scent will leave the fabric and you can add more drops. The bracelet or necklace should be able to protect you for up to 24 hours at a time as the fabric is saturated. And, they can be reused in the future by adding drops.
We can arrange student workshops to teach students how to make their own mosquito-repelling bracelets and necklace. It is a sustainable approach, instead of using single-use mosquito-repelling products. It is also very fun to make and can become a fashion statement! | Repel in Style | Protect yourself from irritating mosquito bites by making mosquito repellent bracelets and necklaces. | ['Chelsea Lee'] | ['School Locker Voucher'] | [] | 4 |
10,486 | https://devpost.com/software/repellent-garden | Our campus grounds can grow a variety of plants which repel mosquitoes naturally. Lemongrass is one of the natural repellents. Citronella (essential oil) in Lemongrass is the most widely used natural mosquito repellent found in sprays, candles, and lotions.
Ways to Plant Lemongrass
To repel mosquitoes with its strong fragrance, we can plant lemongrass along walkways and near to gathering areas. Lemongrass can be grown in large planters so it can be moved around to keep mosquitoes at bay and for pest control. Lemongrass not only repels mosquito; it smells wonderful with a tinge of lemony fragrance. Attractive, easy-to-grow and often used in Asian cuisine (free herbs for students and staff) (very healthy to drink as tea too).
Replace Commercial Mosquito Repellent Spray
Moreover, the chemicals in commercial mosquito repellent spray are not only harmful to the environment, it is also harmful to the students. A pharmacologist in Duke University, in studies on rats, found that frequent and prolonged DEET exposure led to diffuse brain cell death. DEET is common in commercial mosquito repellent. Hence, we should avoid using commercial mosquito repellent and opt for natural repellents instead. It is easy to use lemongrass as mosquito repellent. We just need to pluck and crush the leaves, thus releasing the oil, and rub them directly onto the skin.
Other Mosquito-Repelling Plants
Another plant to grow is Catnip which is one of the most effective mosquito repelling plants and cats love it too. Catnip is very easy to grow - it is a member of the Mint family. A vigorous growing herb in the garden. It has low maintenance, will grow anywhere, and has attractive purple flowers in Summer and Autumn. Other mosquito-repelling plants to consider are Basil, Bee Balm, Citronella, Floss Flower, Lavender, Lemon Balm, Marigold, Peppermint, Rosemary, Sage, Scented Geranium and Pennyroyal.
Student Engagement and Guidance
The campus can have signage near the plants to teach students the use of lemongrass or other mosquito-repelling plants. Hobby workshops can engage students in planting these plants. This will help lower the execution cost and allow students to have the opportunity to learn gardening from a professional. It is a sustainable solution as these plants can be locally sourced, easily grown and do not harm the environment. Lemongrass is a native plant in Australia.

• Mosquito-borne diseases are a major public health problem worldwide. Diseases such as West Nile disease, malaria, dengue fever and Chikungunya fever are undergoing a resurgence and redistribution under global climate change. Mosquito-borne diseases continue to be a serious public health problem and have caused substantial morbidity and mortality in recent years.
• Each February, with warmer temperatures and rainfall, students from The University of Newcastle return to campus to face plague proportion mosquitoes. The common scent of the students is that of Citronella, Aero-guard and Aussie Mosquito Repellent.
• They spray, they swipe, they swear and they share!
• Vision / Solution
• The university should purchase mosquito repellent textiles and create a range of protective clothing for students to wear.
The finish may also be painted onto walls in classrooms.
• The university sells logo polo shirts. Why don’t they use mosquito repellent fabrics which are readily available?
• The university should produce a university protective clothing such as Polo shirts from mosquito repellent textiles. They could further produce a range of clothing and accessories including tops and bottoms, lightweight tracksuit pants, gym and yoga tights, shorts, hats, caps and oils.
• Wearing scented oils mosquitoes dislike such as, citronella, can be one way to keep them away from your skin and blood. Oils and diffusers could be sold and placed in university rooms.
• End-user / Customer
• To ensure safety, we could use smart protective textiles technology. The protective textile field of the smart textiles has created a mosquito repellent textile that protects the human beings from the bite of mosquitoes and thereby promising safety from the diseases.
• The cost should be minimal and an online campus advertising campaign would solution students of the benefits of wearing protective textiles.
• To impart this character a finish of the mosquito repelling agent is given to the textile material. Research and development has resulted in the application of chemicals on textiles which sustains this characteristic and provides reasonable wash fastness whilst considering the ecological and economical aspects.
• Realistic
• Students already purchase logo polo shirts and it would be a minimal change to use and advertise mosquito repellent textiles which are readily available.
• To impart the mosquito repellent feature, the textile material is given an anti-mosquito finish with an agent. This agent is capable of being used on textiles without spoiling their characteristics and has good washing fastness. These finishes may also be anti-bacterial and anti-fungal as well as heat and cold resistant.
• It repels mosquitoes by processing fibre using organic compounds. The treatment is by dipping and spraying fibres and fabrics and is very safe (using the same component as insect-repellent spray content), It has good fastness to laundering.
• The main use in garments and the materials used are cotton, polyester and their blends.
• Responsible
• Ecological and economical aspects are a priority and should be imparted through natural sources to maintain an ecological balance.
• Currently, ecologically friendly finishes, added to fibres are readily available at a reasonable price.
• Future use of Neem leaves as a protective textile is under investigation. | Mosquito repellent textiles | To manufacture university logo clothing that already exists eg polo shirts using mosquito repellent smart textiles which are cost efficient and readily available. | ['Deborah Trevallion'] | ['School Locker Voucher'] | [] | 6 |
10,486 | https://devpost.com/software/killing-mosquitos-with-cashews-shells-and-water-fountains | Where there's a will, there's a way...
Originally coming from Sri Lanka, a tropical country where the mosquitoes are quite abundant at times, we used to have very smart and ecofriendly ways of controlling these biting pests. If you burn the cashew nut shells outside a premise, the mosquitos would be evacuated in no time. The cashew nut shell liquid/oil, is a resin found inside the cashew nut shell. Right now it is used as resin and to kill fungi and termites. Since it is not dissolvable in water, we can mix the cashew liquid with castor oil, or any eco-friendly oil like sweet almond oil etc creating a surfactant, a chemical that allows two liquids to mix. If we were able to spray this to hotspots of mosquito breeding grounds, it will kill mosquito larvae as well as it will prevent mosquitoes from laying eggs in the water at all. The mixture will serve as a repellent as well as a larvicide. The university can also consider installing the essential oil diffusers with these oils in buildings were these mosquito problem is severe, as the aroma will chase them away while being nontoxic and pleasant to human liking.
Other approach we should take combined with this is keeping the water moving specially in the marshy land area in the Callaghan Campus where the mosquitos find breathtakingly attractive for breeding. As long as we create a motion of water using electric aeration pump or a fountain to create motion in water, the mosquito eggs won't survive.
Well, now that we created a beautiful view with a water fountain, with increased aeration in the pond which will make it healthier overall for the other wildlife you actually want, like fish or ornamental vegetation, why don’t we take our innovative idea a bit further? We can add some ornamental fish or other aquatic animals that love feeding on larvae. Some examples include Killifishes, topminnows, tadpoles. Another thing to remember is adult mosquitoes thrive in areas with moist plant life, like the lush vegetation that often surrounds ponds. It would be better if we can regularly cut back overgrown vegetation and remove weeds and dead plants.
Bats, dragonflies, and other animals will also eat the mosquitoes. If you create habitat for these creatures, they’re more likely to hang around the pond and help control mosquito populations. Adding native species should help make it more inviting. It will be an ecofriendly approach if you make an effort to support such conservation efforts in your community to protect natural habitats.
I think I have given quite a few ideas here. By the way, if you want to get very effective cashew shell oil, Sri Lanka will be able to provide truckload of that to an affordable price. Just shoot me an e-mail and I will be more than willing to contact the Sri Lankan suppliers for you supply good quality products for a reasonable price. We might even be able to commercialize this product. | Killing mosquitos with Cashews shells and water fountains | Where there's a will, there's a way | [] | ['School Locker Voucher'] | [] | 7 |
10,486 | https://devpost.com/software/windy-play | In summer, mozzies can stop our kids from playing outside, especially little kids at daycare in mozzie hotspots. We need a kid friendly and environmentally friendly solution.
Solar powered outdoor fans create a wind which mozzies don't like, and they keep the kids cool. This is ideal for smaller enclosed play areas such as those at daycare centres. The fans could be installed under big mushrooms of bright colours. As well as looking fun, the mushrooms protect the fans from the elements. The solar panels can be mounted on top of each mushroom, or the fans can be hard wired underground to the solar source. This solution addresses a couple of issues that kids face while playing outside in summer - the mozzies and the heat. It reduces the need for daily use of insect repellent in little kids (which has questionable safety) and improves the aesthetics of the play space.

10,486 | https://devpost.com/software/project-chewbacia | Mosquito Trap
Imagine a drab coloured bicycle helmet sized container, hidden atop light poles throughout the Callaghan campus that contain a living thing: bacteria that produce an enzyme. What is it? A cunning, highly targeted and sustainable mosquito trap that makes use of natural systems to lure and disable only the highly localised population of this very important participant in the local ecosystem.
So how does it work? Mosquitoes use a variety of methods to find their prey. At distances close to fifty metres the mosquito follows a plume of CO2 created by humans, shifting at approximately ten metres when the mosquito is able to make use of lactic acid and polyamines in sweat to more accurately track targets. From one metre, away heat becomes the final attractant. By manipulating all three components of the mosquito targeting system, we propose a trap and delivery system for population reduction within a localised area. Mosquitos don’t traverse large distances, approximately five kilometres over their lifespan, meaning a strategy of this kind deployed within a limited area like Callaghan will greatly improve the lifestyle of University students, without the need to eradicate the species. This is important given that when not in the breeding state mosquitoes are pollinators, filling vital gaps in the flora ecosystem.
Our trap and delivery design will make use of a heated bacterial system housed within an elevated bicycle helmet sized container. Within the bacterial system lactic acid and polyamine production will generate small amounts of carbon dioxide to lure mosquitoes from up to fifty metres away. Our system will upregulate the production of polyamines and lactic acid to produce the CO2 for the first tier of the mosquitos prey location, as well as producing the chemicals for the second tier of hunting. Heat will be used as an incubator for the bacteria, as well as the final tier attractant. A capture system will be deployed whereby the mosquito will come in contact with an enzyme that effects it overtime: chitinase. Chitinase produced by the bacteria within our design breaks down the exoskeleton of the mosquito at the feet, disabling its ability to recognise prey. In a nutshell: mosquitoes touch and taste the skin when they land and if we don’t feel or taste right they don’t bite. The chitinase will prevent the insects from finding prey after contact.
Is it safe? Yes. Chitinase is non-toxic to birds, mammals, fish and amphibians, so a system of this kind will have little effect on the local fauna. Reduction of the population over consecutive generations will lessen the number of mosquitoes without completely removing the pollinators from the ecosystem. Our system targets the mosquito population without effecting other arthropod species, especially if kept off the ground. There is the possibility to incorporate these systems into existing infrastructure with the tops of lights being the perfect location. These devices would effectively be a small and unobtrusive black dome, out of sight and mind. | Project mKO | We're designing a delivery system that will house a bacteria that facilitates a reduction of the mosquito population within a confined radius. | ['Catherine Mackay', 'Evan Gibbs', 'DoctorKarl', 'Benjamin Matthews', 'Michael Miller'] | ['School Locker Voucher'] | [] | 9 |

10,486 | https://devpost.com/software/natural-elimination | The elimination of mosquitoes is an expectation across the world. But completely eradicating mosquitoes is not realistic. Not every mosquito is harassing humans. “There are 3,500 named species of mosquito, of which only a couple of hundred bite or bother humans.” (Fang, 2010). Mosquitoes spread many diseases and affect human life. The focus is on how to change the habits of mosquitoes. The main effect of mosquitoes on humans lies in sucking blood. How to stop mosquitoes from sucking blood is the most important thing.
Humans have used both genetically modified and physical way to kill mosquitoes. Among them, genetically modified mosquitoes caused serious accidents. Increase the mutation of mosquitoes, and the risk is huge. For example, the genetically modified mosquito experiment in Brazil. “...some offspring of the GM mosquitoes survived and produced offspring that also made it to sexual maturity” (Servick, 2019). There are many products of physical mosquito killer, such as electric mosquito swatter, mainly for personal use. I suggest using Natural elimination.
Use bionic skin to make blood bags. Add a mixture of insecticide and blood to the blood bag. Use electrical heater to simulate the human body temperature. Collect volunteers' clothes after a lot of exercises to restore the taste of the body. Also, spray specific mosquito repellent products. Traps and kills mosquitoes that are resistant to mosquito repellent products and sensitive to human odor in the area. Create living space for the remaining mosquitoes. Then, use specific mosquito repellent can reduce mosquito bites.
This method cannot completely eliminate mosquito bites, but it can greatly reduce the harassment of mosquitoes to humans.

Mosquitoes are a major cause of discomfort and distress in Australia, and in UoN it has become a nightmare for everyone. The global statistics shows a boom in mosquitoes borne diseases such as malaria, dengue, chikungunya, filariasis, leptospirosis and many more. This makes the mosquito as one of the most menacing creature on the planet. Australia is very famous for wetlands, marshes and waterbodies and interestingly these stagnant water bodies are the breeding grounds for mosquitoes. The unnoticed other areas are the sewages and drainages where these mosquitoes multiply. Especially, our University is situated in a wetland area serving as the ideal location for mosquito breeding. Basic research shows that if the breeding is controlled, the population of mosquitoes can be limited. The peak in mosquito population is observed during warmer months when several mosquitoes are suddenly observed. Most of the adult mozzies die after summer but keep their offspring as winter eggs (dormant) in the ground or near the water bodies (some of the female mozzies hide in dark areas). During spring season, eggs merge with water and hatch suggesting water is needed for their breeding. Thus, elimination of mozzies during the hatching phase is the best method of controlling mozzie menace at UoN.
IDEA & SOLUTION
There are number of measures available to control the breeding of mosquitoes and thereby their population. But, most of the existing methods are creating problems to the habitat and ecosystem. In our approach, we are establishing natural biological methods that will not affect the ecosystem and balance the inhabitants around. Introducing guppy fishes (Poecilia reticulate) to the nearby waterbodies and drainage systems and use of BT (Bacillus thuringiensis bacteria) balls for land can considerably reduce the number of mosquitoes. The Guppies are ornamental fishes and they can feed on mosquito larvae and eggs. The research shows that Guppy fishes are one of the five most effective forms of dengue control. The BT balls can be prepared from Bacillus thuringiensis bacteria (toxins kill larvae) by mixing it with sand or compost. Thus, by releasing these tiny fishes in water bodies in wetland areas and around university can substantially reduce the mosquito population. The fish population would add to the beauty and elegance of the place. In wetlands, it does not create any environmental issues as it feeds on larvae and zooplanktons. It can also happily stay with other fishes and is tolerant to Australian climate. Thus, this approach can be established to control the population of mosquitoes not only in the University but also around all the places. The BT balls can be dispersed to various parts of University dry land during winter (by student volunteers) and it enriches the land with bacteria. During spring when the eggs start to hatch in the water logging areas toxins released from BT will destroy the larvae and eggs. The mosquitoes can fly over long distances and this control method is applicable to a wide area making it an effective controlling method. | Guppy-Bac vs Mozzie | Introducing guppy fishes to the nearby waterbodies and drainage systems and use of BT (Bacillus thuringiensis bacteria) balls for land can considerably reduce the number of mosquitoes. | ['Shan Mohanan'] | [] | [] | 12 |
10,486 | https://devpost.com/software/formula-for-mosquito-control | One strategy is to promote avoiding mosquito bites for people with illness, and minimising the ability of mosquitoes to pick up the virus from biting infected individuals. In other words, quarantine dengue patients from others or put them under net. So that spread of dengue infections can be minimised, he added.
The recommendations are:
First, including destruction of artificial containers, source eradication, coordinated community effort, awareness campaigns and change of school dress code as children are vulnerable.
Second, public works including well-organised solid waste disposal, improving water storage practices, regular insecticide deployment and effective public health education, are crucial.
Third, items that collect rainwater or that are used to store water (plastic containers, gallon drums, buckets, or used automobile tires) should be covered or properly discarded.
Fourth, pet and animal watering containers and vases with fresh flowers should be emptied and scoured at least once a week. This will eliminate the mosquito eggs and larvae and reduce the number of mosquitoes present in these areas.
Fifth, for travellers to areas with dengue or malaria, as well as people living in areas with dengue/malaria, the risk of being bitten by mosquitoes indoors is reduced by utilization of air conditioning or windows and doors that are screened. The risk of dengue and malaria infection for international travellers appears to be small unless an epidemic is in progress.
Sixth, if needed, the hospital authorities should immediately arrange additional beds for increased number of patients. No dengue/malaria patient should leave hospitals without receiving the highest possible care. Dengue/malaria patients should receive optimal care and doctors should take all precautionary steps for treatment of dengue hemorrhage fever.
Seventh, preventing epidemic disease requires a coordinated community effort to increase awareness about dengue/malaria, how to recognize it, and how to control the mosquito that transmits it. A campaign for creating awareness, no doubt, is helpful to eradicate Aedes mosquitoes from the capital city and elsewhere in the country. For example a public awareness raising campaign should start over radio and television (also through the electronic, print and other media). Residents are responsible for keeping their yards and patios free of sites where mosquitoes can be produced.
Eight, children are the most vulnerable to dengue/malaria. The school dress code of the schools should be changed for a few days during potential outbreaks. The students should wear full-sleeved shirts. Mosquito nets should be used during sleep. Containers which may be conducive for breeding of the mosquitoes should be covered with white nets.
Last, but not the least, we all need to be united to wrestle against this deadly disease. It becomes clear that dengue/malaria is gradually turning into an "all-weather" health hazard to the people of this country. No country has been able to eliminate this dangerous disease. However, it is possible to keep it under control.

10,486 | https://devpost.com/software/orange-peels-as-a-mosquito-repellent | Having stayed in Ghana for most of my life and seen malaria affect and killed both children and adults, controlling mosquitoes will be help reduce improve the lives of individuals. Also, during summer mosquitoes were a thorn in my flesh, leaving bumps and sores on my body.
These experiences motivated me to take a challenge in creating something to repel these insects.
I am looking forward to develop a repellent from orange peels as locally used in Ghana to repel mosquitoes.
I am likely to face challenges including availability of resources. | Orange peels as mosquito repellent | Orange peels will be dried, grounded and moulded into candles and skin creams. | ['Emmanuel Boateng', 'Ama Ampofo'] | [] | [] | 15 |

Inspiration
I am reflecting on my childhood experience of controlling mosquitoes in rural areas, where villagers and famers are living, in Ayeyarwaddy Region of Myanmar (formerly known as Burma). In the rainy season, the mosquitoes were very terrible, we had to sleep with mosquito net. Before we sleep, in the evening time, there was a traditional way to keep mosquitoes away.
What it does
My father lit the fire with a mixture of wood and pieces of turmeric. When the smoke came out from the burning turmeric, the mosquitoes ran away from the house.
It is well known that turmeric has been a famous home remedy in Asian culture, which has benefits for many health conditions. Also, the turmeric smoke has the power to keep mosquitoes away. We don’t have to kill the mosquitoes, just make them going away.
How I built it
When I am thinking of the idea to control mosquitoes, this childhood experience is coming into my mind. Perhaps we can make the turmeric smoke in form of spray that would not be harmful to the people and the environment. Turmeric plants are very easy to grow, and not expensive.
Challenges I ran into
Mosquito bites in Callaghan campus is very itchy, and it is a serious problems for the persons who have sensitive skin. It can lead to other health problems as well. Knowing that we need to think about environmental sustainability, yet intelligent people are finding the innovative solution to address the challenges of controlling mosquitoes.That's why would like to share my idea based on my personal experience and traditional way of controlling mosquitoes.
Accomplishments that I'm proud of
This natural way of controlling mosquitoes is environmentally responsible.
What I learned
I had learned that mosquitoes scare the smell of turmeric smoke.
This is my real experience, telling me that turmeric smoke is a secret sauce for mosquitoes.
What's next for Spark of an idea for controlling mosquitoes
We will have to do a research project, collaborated with expert in biotechnology, to test whether turmeric products can be used to control mosquitoes. If it works, this will be acceptable to use in the market. That is the spark of idea based on my childhood experience. Hopefully, this ideas is useful in real world.
Thanks for inviting to share the idea.

The most annoying places covered by mosquitoes waiting to attack poor people are at entrances of buildings which inspired me to come up with this idea,
‘controlling the population of mosquitoes at entrance of buildings by installing
smart poles
at these over-populated locations’
.
What it does
Smart poles
attract mosquitos by
light
,
colour
,
smell
, and
diet
, which are attractive to them, then will trap them inside the pole. A specific part,
‘cartridge’
of the pole is design to trap mosquitos via net or other similar equipment, which would be easily accessible by a person to change/empty it and then put it back (it could also be serviced/replaced).
How to build it
The body of the pole could be metal or wood, and its location is as close as possible to
entrance of buildings
, since these are the places people are mainly attacked by mosquitos. The
‘cartridge’
of the pole should be designed at an accessible height, so it could be targeted by mosquitos, and easily and regularly serviced by operators.
The cost of installing these poles would be fairly low, since they are only needed at entrance of buildings. | Smart Poles | Installing smart poles at entrances to catch mosquitoes | ['Mahmud Abdolhoseini'] | [] | [] | 17 |

Mosquitoes are known for their amazing ability to adapt and are considered dangerous because they spread diseases that can kill humans, which they spread through their bite. Despite, the mosquito drinking and ingesting infected blood, the pathogens do not seem to affect the mosquito. These pathogens are then deposited into another person’s blood when the mosquito introduces saliva into the bloodstream. The mosquitos themselves are not what kill people they are just carriers of these pathogens.
In war, if you can make the ally of your enemy your ally this serves to create a great disadvantage to your enemy, which in this case are the pathogens. Therefore, by having the mosquito eradicate the pathogens before it feeds again can be a very useful technique of controlling the spread of these diseases. However, the possibility of this occurring naturally in nature is very low. Hence, this will have to be conducted under laboratory conditions by taking full advantage of the adaptive abilities of mosquitoes to present an inhospitable environment for the pathogens to survive. Gene manipulation is not a new topic, hence the possibility of project success is relatively high. This adaptation is then encoded into the gene mutation of generations to come. When the mosquitoes mate, this gene is then passed to the next generation. Given the rapid reproduction of mosquitoes, the gene will be passed on quickly.
This proposed solution will help reduce the death toll worldwide, however, this will not eliminate some of the irritating behaviours of mosquitoes, but that is a small price to pay for the greater good. This proposed solution will also limit the attempts to eradicate mosquitoes, hence limiting the threat of mosquito extinction, preserving the current eco-systems | Frenemies | Using mosquitoes to our benefit | ['Kudzai Beta'] | [] | [] | 18 |

Many mosquitoes breed in standing water, primarily infesting ponds, marshes, swamps and other wetlands. From these major breeding spots (ponds, swamps and other large bodies of stagnant water), the mosquitoes then spread out in search for food either nectar or blood. Eventually, they locate other minor bodies of water (tin cans, tires, etc) to breed in. When mosquitoes are spread out they become a challenge to deal with.
For the following proposed solution to control this spread it is assumed that mosquitoes hibernate in the cold seasons and initially become active again when the weather warms up but before major precipitation occurs. With the absence of major precipitation, the number of minor bodies of water for the mosquitoes to breed/lay eggs are minimal, hence ponds, swamps and other major bodies of water would be the preferred or possibly the only option.
The idea is to isolate these major sources (ponds, swamps, etc) of breeding and contain the spread of the mosquito population in these areas by strategic placement of the plants (food and repelling). The basic strategy involves initially surrounding the body of water with the required food (mainly consisting of plants) for the mosquitoes. This will prevent them from venturing far from the source of birth in search of food. Then an alternative strategy will be applied, utilising the repelling zone. This repelling zone will surround the food zone which surrounds the water source. This will serve as a two-fold measure, firstly it would discourage the mosquitoes from venturing too far from the water source and secondly it will discourage access to mosquitoes which hibernated out of this area. This will create a virtual barrier limiting the number of mosquitos that escape from the major source of these mosquitoes and the number of mosquitoes that enter this region/source.
Given this arrangement, the mosquitoes will be in a consolidated/controlled state inside the region with containing the water source. This will increase the effectiveness of insecticides as you would only require application to that small area and will ensure that the insecticides affect only a small portion of the environment. However, a better and more sustainable solution would be to introduce predators into this region, primarily frogs and dragonflies as the tadpoles and larvae respectively, feed on mosquito larvae. This arrangement also serves to stop mosquitoes from entering this region to lay eggs hence they will have to find minor sources which are limited before major precipitation, hence the probability of successful breeding is reduced and the majority of the eggs and larvae will die off.
This strategy will see to benefit the human population surrounding these areas and the environment. This will also limit the spread of the hotspots of mosquito disease outbreaks, allowing for distribution of medical supplies to targeted locations. | Ctrl-Alt-Del | cover the spread of Mosquitoes | ['Kudzai Beta'] | [] | [] | 19 |
10,486 | https://devpost.com/software/a-simple-suggestion-for-getting-rid-of-mosquitoes-at-uon | I am participating this challenge simply to share an idea someone talked to me about a few years ago, when we were waiting for the bus and talking and complaining about the serious issue of mosquitoes around the University Callaghan campus. I'm not sure how scientific or practical this idea might be, but as far as I remember, she mentioned that she had biology background.
Her idea was to simply install turbines or similar rotating objects in the University's swamp(s) and stagnant water to make them continuously move, as they are the major places for mosquitoes breeding, egg-laying, and completing life cycle. | A Simple Suggestion for Getting Rid of Mosquitoes at UON | Installing turbines in UON swamps to avoid mosquitoes breeding and egg-laying | ['Behnaz Khavari'] | [] | [] | 20 |
