From the horse’s mouth
,
“In this lithography experiment light creates free radicals from phenylbis(2,4,6-trimethylbenzoyl)phosphine oxide which induce polymerization of 1,6-hexanediol diacrylate.”
Or for those without a Chemical Engineering degree, light from a (high resolution) projector interacts with a special liquid, producing a hard polymer on the surface. A platform within the liquid is lowered, taking the layer of polymer with it. Shine the projector again to produce another layer: lather, rinse, repeat. Long story short, an atypical
3D printer
using
light
on a very
small scale
.
You get the chemicals and lab equipment, we’ll get the laptop and projector, and for goodness sake [Jimmie] stop bumping the table.
[Thanks Tomas]

FYI, 3d-prototyping solutions:SL/SLA: Stereolithography: A liquid bed is hit with precise amounts of UV light, causing the liquid polymer to cure where the light hits. The bed is then lowered and the next layer is cured. SLA allows pretty incredible surface finishes and one of the lowest wall thicknesses of the rapid prototyping solutions.LS/SLS: (Selective) Laser Sintering: A high powered laser hits a powdered metal or plastic causing it to sinter (fuse). After a layer is made a new layer of dust is cast onto the partFDM: Fused deposition modeling: A plastic is extruded through a heated head which moves around. The heated plastic is deposited to build the part. This creates an obviously layered part which loads poorly in shear.Then there are more proprietary solutions like polyjet and zcorp.Is anyone here working on a reprap? I’m hoping to make a reprap with an interchangeable head that would allow use for FDM, a mini-mill, a laser cutter or etcher, and possibly LS or SLA. Ideas?",

You *CAN* polymerize UV reactive chemistries with heat alone but it is markedly easier to use, you know, UV light. You need a lot of concentrated UV light though – if I put my hand in front of the light on my objet printer, I would very quickly get a deep sunburn. It is many times more intense than the sun. Well over 100 fold.An LCD screen has nowhere near that level of UV light and I suspect that you would have a difficult time modifying one – my understand (which may be incorrect) is that LCD screens don’t take well to UV light. Plus, most backlights don’t produce much, if any, UV light in the first place.",

Not sintered metal but a quality plastic with an exceptional surface finish and amazing detail. Think about it. Z axis stepper, some decent software and a projector. There isn’t much to it and the resolution and build times would be superb. As good as a $40,000 machine (which is what a EnvisionTEC costs now) but for perhaps $1500 in parts and starter material. This is something you could easily build as a kit using an off the shelf USB powered servo Z axis and VGA or DVI or HDMI or possibly even USB projector since it is just still images.Bonus points for linux capability!",

I work for an NSF funded center and my job it to take the research from our center faculty and make it accessible to students in secondary schools. The primary motivation is education and to inspire future scientists and engineers. This process is based on some research from Dr. Nicolas Fang here at the University of Illinois. He is making very small objects – on the order of microns to a few millimeters. Our method is a distillation and simplification of his method scaled up so students can see the results.We have the procedure described on our website. On that site we have video of the process as well as the files we used to make several objects. These are PowerPoint files that will also work in Open Office. The site is:https://nano-cemms.illinois.edu/materials/3d_printing_fullOne thing we have modified since our article was published is the solution we use. The new solution works much better and has resulted in much more success. I would suggest using this instead of the one described in the article until you are more comfortable with the procedure. The website I reference above uses the OLD solution and not this new recipe. The recipe for the solution I would suggest is below:98 ml Poly(ethylene glycol) diacrylate CAS 26570-48-9 Sigma Aldrich # 4374412 g Phenylbis (2,4,6-trimethylbenzoyl)phosphine oxide (Irgacure 819) CAS 162881-26-7 Sigma Aldrich #5114470.02 g Sudan I CAS 842-07-9 Sigma Aldrich # 103624The solution requires several days to dissolve – make at least 3 days before use, longer is better.Solution should be stored in an amber bottle.Solution will store for at least a year with no degradation.Several people have asked what lens we use. We use a Plano-Convex Lens 50.0mm Dia. x 150.0mm focal length, MgF2 Coating that we get from Edmund Optics, NT32-975. This is just the lens, if you want a holder as well; we use their holder M54-986 with a mounting post M54-940.",

It is possible to use another dye.Also keep in mind though (not that this justifies using Sudan I) that Sudan I, aka 1-Phenylazo-2-naphthol, is chemically similar to the artificial dyes used in things like Tang. Not that I am arguing that artificial dyes are healthy by any means. But as long as you don’t plan on drinking the dye, avoid skin contact and you take reasonable safety precautions, you are probably ok. Most UV chemicals have a fairly low vapor pressure, something on the order of 0.1 mmHg or so, which means they don’t really evaporate (at room temperature) much compared to say, water.To get an idea of what vapor pressure is, if we were to place a substance in an evacuated, closed container, some of it would vaporize. The pressure in the space above the liquid would increase from zero and eventually stabilize at a constant value, the vapor pressure. The point at which most UV resins “stop evaporating” so to speak means they tend to not give evaporate huge amounts into the air.Both the artificial colors known as Yellow 5 (Tartrazine) and Yellow 6 (Sunset Yellow FCF) are azo compounds. Essentially they are sulfonated versions of Sudan I (the dye being used in this experiment). DayQuil uses Yellow 6 for its color.Kinda makes you want to avoid artificial dyes in your food, doesn’t it?",

I’ve seen UV stereolithography demonstrated at past RadTech conferences and from a couple suppliers a couple years ago.When I read the initial article, I was wondering to myself “why is he using HDODA???” My experience has been that it’s pretty hard/brittle (for a diacrylate) and that there are other (better) monomers to use than HDODA. I would have used TRPGDA, DPGDA, or PEG(400-1600)DA or thrown a resin like Ebercryl 3211 in to give it some “guts”. Irgacure 819 is a pretty good choice but if you’re seeing a solubility problem with the photoinitiator, you could also try TPO-L (Ethyl – 2,4,6 – Trimethylbenzoylphenylphosphinate which is a yellow liquid TPO). You should just be able to stir it in.Shane",

[Mr.X] added
support for four controllers to his Super Nintendo
(
Google translated
) by internalizing the multi-player adapter. In the video after the break you’ll notice that he also added some bling to the case by positioning the power LED beneath the logo and adding a two-digit display. There is a switch on the back that allows him to choose PAL or NTSC standards with the current setting shown on that display. While most people are going with emulators, [Mr.X] ended up with a custom piece of hardware with a clean finish.

(i had a 12v power adapter and no idea what it went to, the laptop uses 19v but they didnt give me a powersource so i had to use what i had lying around) also removed the touchpad. then i gave it to my cuz because his NES doesn’t work worth a damn. removing the screen wasnt a bad idea bc it is way better on the HDTV plus it has yellow RCA out which is not worth using bc that shit is blurry, but yea.. $5 into a very thin pc running xp (performance edition) over 9000 roms and plenty of room to spare, plus it haz cd burner and floppy drive. it is very ghetto. at least i didn’t break the keyboard. then i threw in 2 usb extension cords from dollar tree lol. because they really don’t suck for a dollar, as opposed to their headphones.",

Students at the Rochester Institute of technology have put together this
WiFi hotspot that is powered by a wind turbine and a solar panel
. It gets its signal through a parabolic antenna pointed at a near by building and repeats it for use in the vicinity. They are using a 30W solar panel, along with a 1/4 horse power 90V DC motor to charge two 6V batteries in series. On a windy day, the turbine has yielded 120W. Something interesting to note is a comment they made about blades. Though the ultimately decided to mimic a commercial design for wind turbines, they found the most efficient to be a single wood prop. Unfortunately, that prop was destroyed.

AVR Guardian Filters Out Dogs

"barrier",

"gate"
] |
Cats and dogs can get along quite nicely when they are raised up together. The problem with this type of arrangement tends to be keeping dogs out of the cat box and away from the cat food. [Ryan Meuth] tried out
a simple electronic barrier to keep the dog away
. It uses an IR transmitter and receiver to shine a beam of invisible light across the doorway to his cat room. In the demo after the break you’ll see that he took steps to make sure the cats don’t set off the alarm. The beam of light is set high enough that their bodies don’t get in the way, and the firmware measures the amount of time the beam was broken in order to avoid false positives caused by the cats’ tails. If the dog does try to get into the room it will break the beam and set off a high-pitched alarm sound.
It’s interesting that the dog doesn’t like the sound but the cat’s don’t seem to be scared of it. Also, we’ve got a less-than-ferocious feline that would love to chew on the cord that connects the two modules. Still, it’s a solution that works for [Ryan] and could be incorporated into
an automatic feeder
to keep the dog away from feedings while you’re out of the house.

Take a PIC 24HJ256GP206 processor and add a dash of knock-off touchscreen and a pinch of SD card compatibility for a DIY digital picture frame. [Daniel] wrote his own driver for the HX8347 controlled LCD that can achieve 15 FPS at 320×240 resolution with 16-bit color. As this was a gift for his wife, [Daniel] included a heart-shaped ring of LEDs that fade in and out like an electronic pulse. He notes that the JPEG decoder runs rather slow but that’s mostly because of the bottleneck caused when accessing data from the SD card. We’ve got more pictures and a link to the source code after the break.

I was probably able to get something like 140KBytes/Second that way (don’t know the real speed because of other things going on in the loop). Test different SDCards if you don’t get at least that through put. It stinks, but I am suspicious some manufactures rank their cards by the 4 bit bus performance and let the SPI interface go to pot come development time. I have some Kingstons which test fast (probably over the 4 bit bus) but are suspiciously slow talking to my 24F over the SPI bus.",

Nixie Sudoku: A Look At The Hardware

We’re always happy to receive a tour of the guts that make things work. [John Sarik] posted several
pictures and descriptions of the hardware
that makes up his
Nixie Sudoku build
. The modular design uses professionally made circuit boards which greatly improve the durability of a large set of circuits such as this.
The design draws on good ideas from similar hardware.
The Nixie Duo kit
from Ogi Lumen allows tubes to be mounted on top of driver boards with cascading shift registers for control of up to 8 tubes. The
ArduiNIX shield
makes the high voltages needed for Nixies easy to control with an Arduino. No, [John] didn’t just order these kits and plug them into each other. He designed his own boards to suit his needs. Each driver board can control 9 tubes in a 3×3 grid, all on one PCB. His high voltage board can supply enough juice for the whole system which is tied together with a single Arduino board.
His writeup is quite interesting so do take a look. He also filmed a walk through video which we’ve embedded after the break. It clears up some questions, such as showing the use of a blinking decimal point to indicate the current cursor position.

Android Development 101- Part 2:Graphical Elements

In this tutorial, we will be continuing from where we left off with the “
hello world
” application. This time adding a graphical user interface (GUI) and a “toast”. The GUI will consist of a button, textbox and a label. The “toast” will be issued onto the screen when the button is pressed.
Some may wonder what a toast is. Well, for non-programmers, a toast is a text notification that for the most part is used only to display an error on the screen (I am a big fan of using toasts instead of an alert on the screen as its less intrusive). For this article we will use a toast to display a message on the screen that will take the text in the textbox and issue a “Hello Greg” onto the bottom of the screen. After this article completed you will be able to successfully make toast commands, design the layout of the hello world program, and pull text from a textbox.
We are going to start off by copy our
existing Hello World project
so that we can use the original in every way but have two separate projects to show the difference and both can be used as references. To do this we will right click on the root of our
HelloWorld
project in the right hand pane (Navigation Explorer), navigate to copy (
not
Copy Qualified Name
) and click it. Then find a blank space in the Navigation Explorer, right click again and click paste. You will be asked to supply a new name for this project and whether to use the default location. We will name the new project
ImprovedHelloWorld
and we will leave the checkbox checked that says “use default location”. Press
OK
and the new project will be generated from the old one.
The first thing we are going to accomplish is changing the
strings.xml
file to add another node under
app_name
. We will do this by copying the node above it and pasting the copied material directly under the last
</string>
element. Then we will change the name of the string to press and in between we will write
Press Me!
. Next we will alter the
hello
node and change the text to say
Enter Your Name Here:
instead of
Hello Android, Hello World!
. This being accomplished we now need to design the GUI (Graphical User Interface).
To do this navigate to main.xml and we are going to go over what everything does up to this point. We first off have a node called
LinearLayout
which essentially creates a space for adding objects such as textboxes, buttons and the like and will format the layout for us. So LinearLayout will organize one thing right after the other in a one column and one row type of deal. Next we have a
TextView
which in any other label we could call a label. Now to go over what all of the parameters are in the nodes we just mentioned.
android:layout_width
&
android:layout_height
are used to determine what will happen to an object when it is used within a layout. There are two options when using this and they are
fill_parent
or
wrap_content
.
fill_parent
will do exactly as it states, it will size the object so that it will fill the screen either vertically or horizontally.
wrap_content
will format the object to expand or shrink to the size of the content displayed within. Both of these variables can be used in many different objects including but not limited to
Layouts
,
Text Views
,
Text Boxes
, and
Buttons
. android:text is used in certain objects like TextViews and TextBoxes to display text to the user. As of right now, we are presenting the user with text but calling it from strings.xml instead of entering the text right in the node itself. To reference
strings.xml
all that is needed is to put
@string/pres
s, where press is the name of your variable, inside the quotations.
Now that we are familiar with the terms, we will need to modify this to first house a label, textbox and finally a button. To do this we will simply add a textbox and button since we already took care of the label in the
string.xml
. To add a Textbox we will start on a new line under ending of the
<TextView />
node. Just to be clear I will add code inline and explain why we are adding it afterwards.
<EditText android:id=”@+id/helloName” android:layout_width=”fill_parent” android:layout_height=”wrap_content” />
. EditText will be our textbox in this instance. Also when giving items an ID it is best to follow these practises of adding
@+id/
before your variable name which makes it possible to tie into your
.java
file later. Next we will add
<Button android:id=”@+id/go” android:layout_width=”fill_parent” android:layout_height=”wrap_content” android:text=”@string/press” />
directly underneath the ending of our
EditText
node. Notice we are referencing the
string.xml
and calling the node that says
Press Me!
which will appear on our button now. If you were to run this project now you would be able to see the layout of the program we just made but we are unable to get it to do anything except enter text in the textbox.
This next section will contain a lot of code and I will provide most of the screenshots of the code to help you through. First, it is good to realize every time you would like to reference an object in your layout we need to import it. We will need to add imports for our button and textbox. We can do that bu adding these lines of code to the imports section at the top:
import android.widget.Button;
import android.widget.EditText;
After that we will need to include four more imports, the first being for event listen to add to our button, the second will be for the toast that we will call when the event handler runs, the third being the context of the application and the fourth to get the view of the application and handle the layout and interaction. These imports can be added under the previous ones and will look like this:
import android.view.View.OnClickListener;
import android.widget.Toast;
import android.content.Context;
import android.view.View;
After these are added to your imports we are ready to get into coding the event handler for our button and the onCreate functions, which is called when the program is started. To make things easier and to complement the screenshot, I will post the rest of the code and explain what the important lines are doing and why we are using them.
public class HelloMain extends Activity {
EditText helloName;
We are creating a reference to our textbox above any function so that it only has to be declared once but instantiated many times if need be.
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
// Capture our button from layout
Button button = (Button)findViewById(R.id.go);
// Register the onClick listener with the implementation above
button.setOnClickListener(mAddListener);
}
Above we capture the button from the layout using a variable. With this variable we are going to assign it an onClick Event Handler as shown on the last line above. Below we are creating the Event Handler for it to be hooked in above. After creating this function it will be able to pull the text from the TextBox and display it with static text.
// Create an anonymous implementation of OnClickListener
private OnClickListener mAddListener = new OnClickListener()
{
public void onClick(View v)
{
long id = 0;
// do something when the button is clicked
try
{
helloName = (EditText)findViewById(R.id.helloName);
Here we instantiate the TextBox we declared earlier and capture the Textbox in the layout by finding it by the ID that we gave it.
Context context = getApplicationContext();
CharSequence text = "Hello " + helloName.getText() + "!";
int duration = Toast.LENGTH_LONG;
Toast toast = Toast.makeText(context, text, duration);
toast.show();
The above code will take Context (the facet to our applications enviroment) and and add it to our Toast along with our dynamic CharSequence text and the length the Toast will appear onscreen, which in this case we want it to be longer. It is key to note how to make a Toast as it is more efficient that popping up textboxes to the user as well as it is less distracting.
}
catch (Exception ex)
{
Context context = getApplicationContext();
CharSequence text = ex.toString() + "ID = " + id;
int duration = Toast.LENGTH_LONG;
Toast toast = Toast.makeText(context, text, duration);
toast.show();
}
}
};
}
The last thing we are doing for this function is putting all the important stuff mentioned above into a try catch statement which will try our important code and if there is an error it will display a Toast letting us know there was an error and a message about that error. For functions such as these is it crucial to have precautions in place to catch errors and not have a program force close. It is important to put the user first in thinking about UI and any error messages that might occur. If an error somehow sneaks into your program try catch statements will catch the error and make it “cute and fuzzy” for the user.
Top half of code:
Bottom half of code, elapsed by previous view of code:
After we have coded the main content for our .java file, we can now proceed to run the application and view our completed Improved Hello World program. Notice that when you press the button and your textbox has not text in it that the program will still function correctly. This is a good feature to have so that you don’t start seeing Toasts containing error messages. The completed product should look like this when the button is pressed:
This would conclude our Improved Hello World example but the learning is far from over. Next post we will examine Databases and a look into some simple queries as well as building a database from the ground up. As always, if you have any problems with coding this article, feel free to leave a comment and I will assist in any way possible! If you can’t wait for the next post you can read up on
databases
before the next posting. Until next time, Happy Hacking!

The file R.java located in the Root of your project under gen/ contains all the information to pull your application together and make it work. You will notice that one of the classes here is layout and one is string. Layout references main.xml and the string class references all of our string entries. Because of R.java these 2 xml files are able to communicate even though the XML file strings.xml doesnt use @string anywhere in it. Hopefully this clears that up and that was actually a great question. Any more feel free to ask and I will hopefully have an answer!",

[Chlazza] let us know about their
Xbox hard drive to SATA adapter
, allowing the use of an Xbox 360 (original) hard drive on a PC without voiding the drive’s warranty. Looking for a fun and enriching experience
read: really bored
and inspired by a previous
adapter we featured
, [Chlazza] set out to make their own and ended up succeeding with a board that costs less than $1 in parts. Of course the drive uses its own Fat32 based file system so there is still some hacking to do if you intended to read the data, but this is a step in the right direction.

(Well, that and because I would have needed to put a microcontroller or similar on the board to talk to the USB host to request more power before turning the drive on.)But here I am, looking at first and third party solutions that apparently just plug into any old USB bus with one connector. The engineer in me is cringing.The fact that the official Microsoft device works in this capacity (assuming there isn’t some trick involved, like the USB ports on the Xbox 360 being capable of sourcing more than 500mA) makes me wonder if all the drives Microsoft selects for use in the Xbox 360 have a current draw significantly below 500mA.",

Inspired by a ducted fan project to simulate lunar landers he had seen recently, [Charles Guan] decided to do the next logical thing and
make a ducted fan driven shopping cart
. The first iteration had a bare prop mounted to the front of the cart. Steering was done by mounting a servo to the front wheels. This ridiculously dangerous shopping cart can be seen in the videos buzzing around the halls and parking lots of MIT. The second iteration that has the ducted fan drive seems not only slightly safer, but somewhat quicker as well. He does mention that the prop shape isn’t really optimal for a ducted design, so expect future revisions to be everything you would expect from a fan powered shopping cart.
He has built a more practical mobile shopping cart, if there is such a thing, called
Lolriokart
. This thing probably deserves its own post as well as it is a fully drive-able shopping cart. You can see a video of it in action after the break.

Although there is some controversy of how it got it’s name, it is certainly used for air ducts. And in some circumstances the tape adhesive bond is stronger than the material.

Those crazy programmers over at the Willow Garage are at it again. This time around they’ve created
a robotic wench to deliver the beer
. When thirst strikes you can fire up a web interface and drag a picture of your beer into a shopping basket. Once you submit your order the bot will raid the fridge and return with your frothy treat. It will even open the bottle for you but, as you can see after the break, this is where your beer becomes truly frothy.
So we’ve seen
the PR2 playing pool
, and now as a barmaid. Willow Garage just joined
SparkFun
on our list of places we wish we worked.

Remember those Ebay auctions of air guitars going for several thousands of dollars? We don’t either, but
Theremin Hero
(more info in the
YouTube description
) is about as legit as you can get to actually rocking on nothing but air.
Much like using a
theremin to control Mario
, the vertical antenna acts as the fret board while the horizontal one detects strumming. Combine the output of the theremin with some custom software (yet to be released) and Guitar Hero and you have Theremin Hero Air Guitar.

[Tyler LaVite] tipped us off about
the generator he built
. He combined a 5.5 horsepower Honda motor with a 10 horsepower electric bandsaw motor. To get an
induction generator
to produce alternating current you must feed electricity into the system to start the magnetic flux. [Tyler’s] solution was to include a bank of capacitors totaling 230mF which charge from the motor, then release back into the system. It’s not as green as the
syngas generators
we’ve seen since it still uses fossil fuel, but it reuses old parts sending less to the landfill.

Alternators typically have to run at a constant speed which makes them useless for wind powered generators (which is what I’m working with atm,) but since you’ve got the lawnmower engine I wonder if it has sufficient RPMs?Anyhow, cool stuff — this got a few ideas going in my head for my own projects.Thanks!",

"content": "Sorry to chime in years later. Just a bit of clarification for future readers. Your prime mover is the engine. It is used to move motors.Take an Hydraulic system for example. Whether I use a tractor PTO or a portable, Honda gasoline engine to turn a hydraulic pump, the primary mover is my engine. So, the tractor is my engine, the pump is a pump, and all the hydraulic motors I turn with the pumped fluid are motors. The same if I used Tyler’s Honda machine as the engine rather than the tractor to power my hydraulic system. His Honda would be the engine.Fire department guys tend to always think of their truck as an engine, because it the prime mover for multiple systems, including pneumatic, hydraulic, and water pumping systems. So, they will sometimes incorrectly look at Tyler’s Honda and say, “That isn’t an engine, that’s a motor.” But they are wrong about that. Tyler’s Honda in his electricity producing setup is indeed the engine.It can get more complex. Personally, while I may refer to Tyler’s JET electrical bandsaw mover as a motor, in this setup it is correctly identified as either a generator. That way you won’t get confused as you add electric motors downstream which move other devices.Last example. Say I use a Ford truck with a PTO as my primary mover. That becomes my engine. I attach an electricity generator to the PTO. That is my generator. I use the electricity generated to turn an electric machine which drives two belt driven water pumps. That electrical machine is a motor. I also use electricity to turn a second electrical machine which turns an air compressor pump. That second electrical machine is also a motor. With my remaining electricity I turn yet another electrical machine which turns an hydraulic pump. That third electrical machine is also a motor.In the cases of the air compressor and the hydraulic pump driven by your electrical system, that opens up even more to think about. Now you can set up your pneumatic and hydraulic systems. Remember how the conversation with your firefighter can get confusing because in his or her profession, the truck is always the engine? Now, when you are talking to a hydraulics guy or a pneumatics guy or gal they are going to want to think of your electric motor that drives the air or hydraulic pump as the primary mover in the system in which they specialize. They will want to call it the engine. Haha. Fun!But it all starts to make sense once you start to think about primary mover = engine.",

Here’s a couple of videos of
Rube Goldberg machines that [Austin] built
. The one above was completed in 2008 as a commercial contest entry for something-or-other. After the break you can see his build from 2007 which was just for fun. Both are quite nice additions to our collection of
the complicated devices
. We especially like the use of a sub-woofer to move a ping-pong ball and a vibrating cell phone for some wireless integration.

Key Fob Programming
|
Mike Szczys

[
"HackIt",
"Repair Hacks"

[
"fob",
"key",
"keyless",
"reprogram"
] |
[Fileark] has
instructions for reprogramming keyless entry devices
for your car. His demonstration video, which you can see after the break, shows how to make one key fob work for two different vehicles. In this case he’s working on a couple of Chevrolet trucks but there are instructions for GM, Ford, Dodge, Toyota, and Nissan. If you need to reprogram one of these you may find this useful, but we’re wondering how it can be incorporated into a project. If you can sniff out the communications that are going on during the programming you should be able to build and pair your own devices with a vehicle. Wouldn’t it be nice to
incorporate your keyless entry into your wristwatch
?

Now get out of the car and shut the door, put a second key in the door handle, then turn and hold in the lock position, while holding in the lock position, press the lock button on the remote you wish to add.I’ve got two 2004 Jetta wagons that each use the same key. I’m going to add a 2004 R32 as well, just need to order the tumbers. Starting in 2002, VW and Audi came out with Immobilizer 3, in which once a key is adapted to a car (Immobilizer serial number), it gets locked down. I had to pull my wifes instrument cluster out of her car and adapt it to my car, return it to her car and adapt the ECM to the instrument cluster. If you scan her car, it pulls up my VIN and Immobilizer info. I will do the same with the R32.2000 and 2001 models use Immobilizer 2 and the keys are not locked down, so it is a matter of just changing the locks then adapting new keys to the immobilizer system.",

Remotes are original VW too.What FINALLY worked was a modification on the above: Put working key w/ working remote in the ignition, turn it all the way on but do not start engine. Step outside, windows closed, close driver side door. Put key #2 (the one I want to sync) in the door lock. Press ‘lock’ on its remote for a couple of seconds. Nothing happens, and nothing’s supposed to happen. Let go of button, turn key to Lock (central locking should now lock all doors), turn key to Unlock (central locking should now open all doors again).After this, finally, I have two working remotes again.

Do-it-yourself remote programming has been common knowledge since the internet was the internet, users have been programming their own key fobs since cars had the freaking things.Show me a key fob that has been hacked to mimic two different key fobs, WITHOUT LOSING SYNC, and I will acknowledge THAT as a hack.The only hack here is whomever thought this was actually a hack.

DelFly2 And DelFly Micro

The video you see above is the on board footage of the
DelFly2
autonomous
ornithopoter
robot. Weighing 16 grams, it carries a small camera and can provide a live feed. If you’re amazed at the tiny size and weight of the DelFly2, check out the
DelFly micro
, video after the break, that weighs 3 grams. Remember when
we thought 17 grams was small for an ornithopter
?
All processing for the DelFly2 is done at a base station and transmitted to the flying bot to keep the weight down. The team also had to create their own brushless motor that runs at 60% efficiency and weighs only 1.6 grams. The 130mAh battery can sustain 15 minutes of horizontal flight or 8 minutes of hovering.

This article will focus on developing a simple hello world program for android using Java. Google has recently released a “
cute and fuzzy
” programming environment for beginners to get into but I haven’t had the chance to try it, so we will be focusing on the Eclipse IDE here, which you should have set up in the
last post
. When creating a text based project there are two very important items. It will involve creating an android project, going through the necessary steps to complete both the (1) XML files and the (2) Java file and get this project ready for production and eventually deployment. The requirements of this project are simple, know the basis of XML (for new comers if you don’t that’s OK too, you will learn) and know Java (very basic knowledge but you will learn as we go and we will modify a few parts of the java file today).
Start by firing up Eclipse and clicking
File
,
New
then
Project
. We are going to navigate to
Android
folder and select
Android Project
and click next. If you have updated your Android SDK correctly, your next screen will look like this. This screen requires we enter all data correctly including Project Name, Build Target, Application Name, Package Name, Create Activity, and Min SDK Version. These are important terms to know because they will control what keywords you can access and what your project looks like when you first create it. So to summarize:
Project Name:
Will be the name you would like to use for your new project. In this instance we will use “HelloWorld” (I am a programmer and loath spaces you might choose to have them but it shouldn’t make a difference)
Build Target:
This will specify what API you will be utilizing in your projects. It is key to choose wisely or you may lose out on a wider audience than anticipated. It is always best to think of what your program will use and see if a lower build will support those functions before cornering yourself with a higher API. For this program we are going to choose Android 1.5
Application Name:
Will be the name you choose for your Application to be called. This can be changed later on and for right now we make that field equal Hello World.
Package name:
The package name will consist of your company’s standard package name that you would use or in my case I use my entrepreneurial one. For this I am entering in
com.gregrjacobs.helloworld
but you can enter in anything you wish. Also, make sure it is in all lower case for good coding practices.
Create Activity:
You will want to make sure that the box is checked before
Create Activity
because this option will do most of the work you just have to give it a name. NOTE: do not call this “Activity” as your project will cease to function and you have to go through the pain of making it all over again or manually correcting it. I am going to use
HelloMain
as my activity name, again use what you wish though.
Min SDK Version:
This will have to be a number you enter denoting the platform you would like to target and if this application will show up in the marketplace of certain devices. If you look to the build target devices after platform tab on Android 1.5 you will see the number 3 and that will be our minimum SDK Version. Once everything is filled out press
Finish
.
This will create the core of our project ranging from the Android 1.5 JAR file to our Java and XML files. The most important things right now are the files in the src/
com.gregjacobs.helloworld/
folder and the files in the
res/
folder. First we will look at the
main.xml
which is located in
res/layout/
. This file will hold the layout of your application including textboxes, labels, dateTimePickers and the like. In the
main.xml
we will see that we are using a LinearLayout which will organize items into a single row or column. This can be handy sometimes (other times not so much) and for this example it will work, so leave it like this because we will be displaying text so it makes no difference. Next is the
strings.xml
file which will conveniently house
all of strings in the application. This is especially useful to keep the clutter out of your Java and
main.xml
file. We are actually going to change the string called “hello” from
Hello World, HelloMain!
to
Hello Android, Hello World!
And our string named
app_name
can stay how it is.
After doing this we are going to navigate to the package name we created and open
HelloMain.java
and this will contain the code to run the XML files we were just looking at. The first line will contain our package name that the java file is associated with. Next, in the picture above, we have imported the OS bundle and the activity function that will run our app. Later on when we explore adding textboxes and labels we will be importing widgets into our files and we will put the imports just under these two shown above. Next is our class that basically says when the application starts up, set the view of the screen to the layout labeled
main
. This is interesting in the sense that you can design many different layouts depending on the state you application is in. Of course with a hello world program we only need this one layout but the option is there for you to experiment with.
When we are done tweaking everything we wanted, we are going to build the application and run it on the emulator we created
last post
. To do this we go to the top of the eclipse screen and navigate to the button that looks like this
and press it. This will prompt you to say what type of project you would like to run. We want to run an
Android Application
and press ok.
The emulator should pop up onto your screen and load up. The first load time of your emulator will be atrocious but after that you should have no problems with load. When the emulator is done loading it may ask you to press
Menu
to unlock, do so by pressing menu just under the screen. You don’t have to navigate to load your project it will do it by itself it just has to load the rest of the software and you should end up with a result like this:
When working with tools like the eclipse IDE and AndroidSDK, making simple text based programs is a breeze. The next post coming to this series will get somewhat more difficult by developing an improved Hello World program. If anyone had any problems with this today make sure to leave a comment and I will try to get back to you before the next post. If you can’t wait to look ahead to designing an interface for your android application or looking into databases, these are the places to go;
Data Storage
and
User Interface
. Until next post, happy hacking.

[Katrin Baumgarten] has fourteen
switches that are made to gross you out
. From a button that retreats into its hole as your finger approaches, to a mysterious goo-oozing faceplate, to a hairy housing that gets aroused as your try to flip it on, the intrigue is enough to get you to try out the next creepy node in the network. There’s a clip of several different switches after the break and if that’s not enough she’s got more on
her Vimeo channel
.

Foam Board Servo Driven Arm

[Lucky Larry] posted some pictures to the Hack a Day flickr pool that caught our eye. He
made a quick and cheap servo driven arm
. Constructed from foam board and some hobby servos, he’s using an Arduino for the brains. You can download the pattern for the arm pieces as well as the code on his site.
He ultimately finds that he has positioning issues that he blames on the cheap servos. You can see in the video on his site that the circles it is drawing are drifting one direction.

However I’ve not used the arm alot and with repeat use the foamboard wont last, so now I know its working (kind of) I’ll rebuild with better materials.The base did move around alot, but because i’d taped down several sheets of paper but not all that well and as the pen caught in the paper edges, the base moved. (also the video is after its been runnign for a while)Other thing I think you can see is only 2 joints move, the 3rd one nearest the pen can’t draw enough power.",

Arduino Space Program

With the recently
proposed cuts to NASA
, our friends across the pond (in Northampton UK) decided to take action with a space program of their own… at least at a miniature scale. NortHACKton, a hackerspace in Northampton decided to host a rocketry day consisting of rockets powered by chemical reactions, pressurized water bottles, and even one that employed an
Arduino controlled launch system
, akin to a few we have
seen
in the
past
. It essentially consists of a countdown and automated ignition system.
Schematics
and source code are available for those adventurous enough to embark on missions of their own.

[Andrew] tipped us off about his
Cable Cam
built out of some lumber and clothes line. It is small enough to fit into a backpack, includes a safety line and the camera can pan and tilt. A future version is planned with a small remote motor to move the trolley more effectively.
[Andrew] accidentally linked us to his other
Camera Crane
, taking the same ‘
cheap
yet effective’ approach as his Cable Cam. Once again, just some lumber and creative engineering are used to pull this one off.
For those without the ability to weld, check out [Bill Van Loo’s]
all wood version of a Camera Crane
. Same parallelogram design, without remote video output or central pivot.

We looked at [Gerry’s] PLCC based programmable Game Boy cartridge
back in May
and mentioned that he was working on a how-to video. He did quite a bit more than that. He’s made
a PDF version of the instructions
but went into deep detail with a collection of four videos on
his YouTube channel
. We’ve embedded all four after the break. They include an introduction and background about the cartridges, desoldering the ROM chip, preparing sockets and wire, and making the solder connections. Whether you’re interested in this particular hack or not, seeing [Gerry’s] soldering practices make the videos worth watching.

I used a spare X10 Eyepiece that I had lying around and used it for the camera. I’m currently using X20 Eyepieces. I also purchased a X2 Barlow lens to bring total Magnification up to X180.

Panoramic And Spheric Tripod Rig

"arduino",
"camera",

"servo",
"spherical"
] |
This simple yet precise build takes your camera for a spin in order to
take spherical and multi-row panorama photographs
. The rig mounts to a tripod, using two servo motors for motion, producing images that can be stitched together perfectly. An Arduino handles the hardware with an LCD interface for dialing in the settings.It’s not
the cheapest way to get 360 degree shots
but the
example
images are amazing.

Want to annoy fellow fans but don’t have the lung power to do the job? [Hunter’s]
electronic vuvuzela
is just the thing you need. The plastic noisemakers were so prevalent at the world cup this year that some
folks came up with audio filters
to remove the sound. The electronic rendition is much smaller, using a 555 timer to mimic the instrument on a small speaker. [Hunter’s] build has buttons for five different notes which can be altered with some potentiometer. There’s no schematic but then again for something that’s annoying you don’t want to make it too easy to replicate.
Update:
Hunter added the schematic to his site which spell doom for those who enjoy peace and quiet.

This sequencer, called
Drumssette
, uses audio tape to churn out some beats. [Mike Walters] built this around a Tascam four track cassette recorder. The tape inside has a different drum sound on each of the tracks, with a corresponding row of red buttons. Pushing a button adds the drum sound to the loop on that beat. He’s using a series of digital logic gates to patch through the sounds as well as clocking the device from one of the tape’s tracks. It’s pretty neat to see the focus selector used in the video after the break to sync up the beginning of the repeated drum patterns. This isn’t the first time we’ve seen [Mike’s] work. If you missed it last year take some time to review the
Melloman

Update: Acrobatic Quadcopters Team Up
|
Mike Szczys

[
"Robots Hacks"
] |
[
"lift",
"quadcopter",
"swarm"
] |
We usually envision small wheeled robots when we thing about swarm robotics but these
cooperative quadcopters
make us think again. This is an extension of the same project that produced those
impressive aerial acrobatics
. It may not be as flashy, but watching groups of the four-rotored flyers grab onto and lift loads is quite impressive. There is also a shot of one dropping a 2×4 and immediately compensating for the loss of weight. We’re not certain, but it looks like team lifting doesn’t require the 20 high-speed camera rig that the acrobatics did. We’ve embedded the demonstration video after the break.

The computer uses multiple cameras to figure out the position of the dot in space. You have to have a lot of cameras in order to have a large area that you can move through.

Sometimes we put a lot of force on the knee, which makes it wear out faster.As for the purpose, we have a computer simulation of the human knee that models all of the ligaments and muscles and will deform accurately. The model could be used for coming up with ways to treat knee damage like a torn ACL. The motion analysis rig is to figure out the position of a person’s knee while they walk around. We then make the cadaver knee move the same way that the living person’s did and measure all of the internal forces. If the forces we measure match those predicted by the simulation then the simulation is good.We also have a setup for figuring out the motion of the scapula, but that’s in the process of having the bugs worked out.@Lars The cameras are connected to a dedicated computer provided by Vicon that works as a hub for the cameras and other sensors (EMG and force plates). They have a custom 8 pin circular connector, but I’m almost positive that they’re LAN. The PC is running XP and the program for motion analysis is Vicon Nexus. You can get the motion data in real time and interface with it in LabVIEW, which is probably how they control the quadcopters.For pictures, I could post the links here or email them to you, whichever you would like.

HaD Community,
We’ve heard the feedback, death threats and *sigh*s regarding the more accessible “top X” posts we’ve published recently. we’re going to pause on these while we internally discuss the mission and goals of Hackaday.
For background, I came up with the name Hackaday while brainstorming a site for hacks with [Phillip Torrone], who was then working on a hack every two or three weeks for a new blog called Engadget which [Peter Rojas] and I had founded. When we sold Weblogs Inc, the parent company of Engadget, Hackaday and 100 other blogs to AOL I pulled Hackaday out of the deal at the last-minute.
Why? Well, let’s just say that this dark overlord realized the dark overlords at the bigger Death Star (known as Time Warner) would not take kindly to having their set-top boxes and DVD players hacked. The head of legal department at said Death Star almost exploded when she read Hackaday.
Hackaday then existed in a shell company before I bought it from my former partners at weblogs inc. I did this, as opposed to selling it or shutting it down, because I know Hackaday is a unique place for a unique group of folks to share what they are working on.
My thinking has been “as long as I don’t lose too much money on this I’m fine with HaD just chugging along.” I’m happy to say that while I’ve lost a little money it’s not a lot (well, not happy, but not devastated. :-)
All that being said, I’d like to see Hackaday grow and expand its mission beyond “one hardware hack a day.” That’s why I asked the Hackaday crew to set up
answers.hackaday.com
and try out a Q&A forum for folks… which you guys seem to have embraced and used. It’s seems to be getting some traffic and is providing some utility.
What I’d like to see is for “classic hackaday” to expand into a place where a wider audience can learn and be inspired to hack *anything*.
So, if a casual internet users wants to rip their DVR apart and try upgrading the hard drive we should be the place they can learn how to do that. If they have a problem, they can ask a question here too.
If someone wants to jailbreak their iPhone or rip their iPad apart and embed it in the dashboard of their car they should be able to do that here.
… or if they want to learn some life hacks related to their Gmail account, we have a long article with the top 25 lifehacks for that.
So, my proposal to the community is to:
a) Keep doing exactly what we’ve done an RSS feed called “classic”
b) Expand the mission statement to something along the lines of “hack everything” (or maybe “hack anything” sounds more ambitious/fun?). Perhaps best said is: “hack everything, and inspire and help others to do that same.”
Thoughts? Feedback?

It is very refreshing to see the owner interacting with and taking the input of the community(since you usually have other projects that you are primarily involved in).I would love to see people think of Hackaday as a resource to learn hacking. I don’t think it should be limited to electronics either.Look at the new Android dev series Greg is doing. That is fantastic in my opinion. It brings in the beginners and educates them. I’d like to see us do the same thing for microprocessors, fabrication etc.Software reviews and tool reviews have always been welcome, as long as they are tools that pertain to us as tinkerers. We shouldn’t limit ourselves to the most complicated, but personally I think we should strive to be easily distinguishable from the plethora of other sites (gizmodo/engadget etc).",

But this is simply not the place to publish it.Forums to discuss, improve, develop proyects: YESHack a day hardware/software posts: YESWhat attracted me to this place in the first time was it’s simplicity.A single, useful, interesting post every single day.Anything from a single-wire mod hack all the way up to completely rewriting a devices firmware to do “extra stuff”.Now, it seems HAD is simply trying to cram anything that ends up on their hands into the poor site. Even simple details like how I’m now able to use CaPiTaL LeTeRs seem to have destroyed the original (in the sense of creativity) idea of lowercase only posts.I don’t mind having several articles a day… but let’s just take care of what’s being published here.I’m glad you took the user’s comments seriously… it really shows how much you do appreciate the site.Let’s keep the spirit of HAD alive. :D",

Much of the article dealt with assumptions and misunderstandings that ran so deep that at least two of the suggestions didn’t even make any actual sense in the context of the subject matter of the post.In short, appealing to a broader audience is fine – but when your writers can’t be bothered to write articles that are actually correct, your readers are technically savvy enough to notice, and complain vocally. I’m sorry that some of those complaints seem to have involved threats.",

Not so sure about the ‘top x’ posts, but a tutorial dev series from HaD are right what I need.And, if they can attract a slightly larger (not even much wider) audience and make some $ at it so it can stay running, I’m sure not going to bitch about posts I can just ignore!",

We have a guy who is building a louvered vent system that will open and close based on the PC’s internal ambient temperature, another who is building a complete dual loop water cooling control center from an arduino. PC Modding is hacking at its core. They take a product that does not function the way they want it to, and hack it so it does. A while back one of the HaD post stated that HaD does not post case mods. Yet we see file cabinet servers, duct tape servers and the like. Those are case mods.I personally think HaD is the perfect place to offer up tutorials and expand on to more tech related things. Communities like HaD and the one I manage have to expand to keep up with the changing times. There was one point where we only posted case modding articles on our front page. When we added a reviews section our front page traffic increased drastically. So what ever you decide to do I will remain a loyal reader and will continue to support you guys in any way possible.",

Not the post of the site, that was just a lead-in, but the linked articles. I think the problem is the quality of articles outside the site, or the lack of finding quality articles.And maybe, at the end of the day, it’s the commercial pressures that apparently don’t exist that are causing the problem. The owner wants the site to expand, but I can’t see that happening naturally the route that has been prescribed – software reviews? Forum, yes, so people can discuss. How-to’s – sure. Feature articles to get people started in an area – sure. But somehow it just doesn’t cut the mustard any more. Maybe I’ve out-grown it. Maybe the lack of “progress” that so upsets the owner is what I like. It’s not a sell-out instructables type nonsense site full of half-useless tat created by people in a blue-peter-esque way with sticky back plastic and blue card.The problem, as I see it, is lack of quality contributions. The staff are posting what they see fit. In order to keep up with demand some of it is a bit questionable, now the questions are raised some more fields are added to increase the post count and target audience, only the existing audience is still wondering where the quality is, no what other fields they should be looking at.The front-page, wordpress nature of the site (good god, there are better solutions, surely) is not really suited to a variety of fields. It no-longer feels like it is about a bunch of knowledgeable people about things of interest, but anything found to fill a space, and the layout means its all just dumped there for all to see, like it or not.Pah, not sure where I’m going with it. If I’m so genius why don’t I start hackitall.com eh. dunno.Yours, confused",

While the second controversial article (the one covering Twitter apps) was of much higher quality, it still isn’t a hack and thus doesn’t belong here.I understand the need for broadening the user base and if these changes must stick, I would ask for additional RSS feeds that do not list non-hack posts and/or feeds that can omit certain authors.",

Android Development 101 – A Tutorial Series

Android is the prime OS for developing applications in today for many reasons. The main reasons being that it is Open Source and Intuitive. In addition it uses Java for development, which is quite an easy language to get used to and develop in. This being said, a lot of you have great ideas for Android applications or applications in general but don’t know where to start. This series will take you behind the scenes and introduce you to the software that will be your best friend while developing for android. On this journey we will start with a “Hello World” and move on from there to create a database driven application with a touch and scroll interface. The final result will look something like this:
Working with tools to develop Android applications will be your greatest asset as you will come to realize early on. All of the tools I use will be listed to make development speedy and efficient while still looking good along the way. At best you will need to acquire
Eclipse
, I recommend the Eclipse IDE for Java EE Developers version as it is amazing for other types of development as well. The next tools you will get are the
Android SDK
, which allows you to hook the SDK into eclipse to reference its API and design an efficient functioning program. After that, this part is optional, look into
DroidDraw
which is essentially a GUI for designing the interface side of things so that you don’t have to blindly hack your way through the Android SDK and Java jungle.
Eclipse is fairly straightforward to setup and start using the Android SDK, you just have to download a package to include the SDK to Eclipses referenced files. To do this we will go to
Help
and then to
Install New Software
. We want to click
Add
to be able to look up just Google’s packages they want us to download. In the location field enter
https://dl-ssl.google.com/android/eclipse
and click OK. Check both boxes and proceed to the next screen. You should make sure
Android DDMS
and
Android Development Tools
are both listed before going on. Accept license agreements and click Finish. You will have to restart Eclipse but after that your hook in is ready to be setup.
Android SDK is fairly straight forward to download for any system but updating it and hooking it into Eclipse is the key. After downloading the zip file (I’m using Windows/Linux but Windows examples will be default), unzip it to your C Drive and label the folder it will enter AndroidSDK. After entering said folder double click on the setup icon which will take you to the screen that shows you all the updates available for download. Download the latest updates and proceed to the top option
Virtual Devices
where you will make your first emulator. NOTE: if an update list does not show you will have to set the setup client to use http instead of https. When creating the emulator the name doesn’t matter and all you really need to set is a version you want to develop on. We will pick Android 1.5 from the list because if you decide to market an application you can reach more people and for the API’s we will use we don’t need 2.1 or 2.2. After setting up your emulator you are ready to have the two meet for the first time.
Going into Eclipse you will click the
Window
button and navigate to the
Preferences
option and click it. Select the Android option on the left and there will appear in the right side of the window a blank screen with a browse button. Click the button and find your AndroidSDK directory in the C drive and select that folder. Clicking
Apply
will make the blank window you were looking at show many different versions of the Android SDK and if you are able to see it you are on the right track. Click
OK
and we are ready to start developing.
NOTES: DroidDraw will be spoken about in another post in this series and we will use it to make part of our interface and the other half we will code ourselves. For everyone else developing in Linux I have found an
awesome post
that will describe how to set up your environment for Ubuntu and can possibly be transitioned for Red Hat and the like. Anyone who is having trouble feel free to let me know the issues you are having and I will try my best to not leave you behind before the next post.
If you can’t wait for the next post, browse the examples on the
Android Developers website
.

The instructions you gave here went through with only one minor hitch. (I had to restart Eclipse to get it to reload the target list in the last step, but I had installed them after starting Eclipse.) All else looks fine.So do I have to worry about using 3.6? I noticed other people had problems with it, and the Android site does have a rather firm warning. Having gone through this, though, I’d prefer to continue rather than start again with 3.5.Thanks for a great series!",

This long bike
is built for haulin’. After needing to find a truck to transport his welding equipment (ironically in order to build
another bike
) [Nick Johnson] decided it was time to make a two-wheeled cargo transport. He extended the frame in order to add a cradle in the front. Eventually there will be sides on that box but for now it works like a charm for transporting his groceries. With the long wheel-base this should be pretty stable as long as you balance your cargo. We’d certainly be more apt to try a ride on this rather than
the double-decker death-trap
from a few weeks ago.

Top 5 Twitter Clients For Android
|

"twitter"
] |
With the growing popularity of the Android OS for smartphones, it has become a contender for the likes of Apple’s iPhone. With the rise of Android came the facet it revolves around; Open Source. Besides it revolving around being open sourced it also has deep roots with social media. There has been an outbreak of different Twitter applications for the Android devices, each with their ups and downs suited for different types of users ranging from the socialite to the power users of twitter. These are the top 5 Twitter clients for Android (A phone running Android 2.1 OS – Éclair – will be used but most of these will be compatible with 1.5 & 1.6 OS and will be stated if they are not available to all OS versions) :
Twitter for Android
(Free)
This is the official application for accessing Twitter from your Android mobile device. Developed by Twitter themselves, it is the most comprehensive application on the market considering it was developed by the creators of Twitter. This has everything the average socialite would ever need as well as having the features Power Users will crave. Here are some of the pros and cons:
Pros:
Interface:
The interface of Twitter for Android is very crisp and concise for you to navigate to what they want quickly and efficiently. When first starting the app, you are presented with options of what they would like to do such as view tweets, lists, mentions, retweets, direct messages and view profile. It seems that the developers of Twitter for Android have taken a page out of Google’s handbook because load times are blazingly fast. The toolbar at the top of the application contains the ability to post updates to your page and to find certain tweets or people based on keyword and/or location. As well, the location map marker in the corner which will allow finding tweets closest to your location. It is also good to note that the Twitter logo at the top left of any screen will direct you back to the main menu.
Speed:
The loading times, as mentioned above, are quite fast. This is excellent for the user on the go who doesn’t want to wait around for the whole application to load before submitting a tweet. This may decrease on users with less RAM but not by much.
Trending Topics:
When navigating to twitters site a lot of trending topics appear. Bringing this feature to the mobile community and making it look good requires some finesse. Twitter for Android has been able to do this quite skilfully, having that little blue bird at the bottom of the main menu tweeting three changing trending topics around itself. This is quite innovative in itself because as of right now the UI for Android apps has been quite lacking but this goes to show that if you really dig into Android you can receive the same quality UI as an iPhone has in terms of apps.
Cons:
Availability:
Twitter for Android is only available for users with the 2.1 OS (Éclair) which will unfortunately leave out the fragmented versions of Cupcake (v1.5 OS) & Donut (v1.6 OS). This will be quite disappointing for most users out there since those versions lead in numbers (until updates are released).
HootSuite
(Paid & Free)
Price: US $2.99
This is the next best thing if users out there aren’t interested in an official application for Twitter. Hootsuite enables users to manage multiple Twitter accounts, as well as being a dashboard for many social media outlets. It contains the usual suspects; Facebook, MySpace, LinkedIn and Foursquare but also allows room for lesser used networks or hubs such as Ping.fm and WordPress (just added). Since being designed for the Android, HootSuite has trimmed down the interface and as of right now the user is able to only post tweets. This client is available to all versions of Android including the latest FroYo build. You should also note that the free version does not include stats and is limited to 3 accounts. Here is a look at the good and bad:
Pros:
Scheduling:
The ability to post tweets at certain points throughout the day without having to login to Twitter every time to do so is very desirable. If the user knows what they will be doing at a certain point throughout the day then scheduling updates for those times is a great way to not deter them from what they are doing. All that needs to be done is tap the top right button and click on the calendar button to schedule a date and time.
Statistics Tracking:
The greatest thing about HootSuite is the statistics tracking that is tightly integrated with the client. When on the main page, press the menu button and click on Stats to see the number of clicks per tweet you have made (accounting for the fact that you put a link in your post) as well as the rating of the tweet you made based on the number of clicks it has received. This is very useful information to monitor how many clicks you get per post and what keywords were used to get that many clicks a post.
Cons:
Very Chatty:
This particular client, when it loads, will load all of your accounts and lists and try and update them all at once. This can make for a very slow beginning to your tweets throughout the day. As well to note, if you have a task manager, it would be best to avoid ending HootSuite completely to avoid the clunky start-up it every time you press the icon. The best way to do it is use Androids multitasking capabilities to start the app then go do something else on the phone while it loads.
Twidroyd
(Paid & Free)
Price: US $3.99
With Twidroyd being claimed as the
“industries standard twitter client”
, this app has a lot to live up to. With such high hopes comes a high feature base including but not limited to, the ability to add plugins, edit lists, native bit.ly support and tweet outbox incase you are disconnected from your network. These features will only be available on the paid version but the price would be well worth it just for the ability to use plugins. This client looks like it has a lot to offer so let’s take a look at the good and bad.
Pros:
Layout:
Twidroyd has a simplistic interface and an easy learning curve. Buttons are easily identifiable and don’t leave you wondering where the hell you’re going. This is the type of an app that a power user and just your average socialite would use. Easily adaptable to any user is its strongest suite, if a casual user doesn’t want all the extras they don’t have to use them but they are there for the power user if they so require.
Plugins:
Want to extend your twitter client to be able to view your position on a map or maybe one to read out you notifications to you? Well Twidroyd has you covered! This is an amazing feature to have because it leaves the platform open for innovation, which if I remember correctly, is Google’s concept of Android.
Cons:
Free Features:
This is an amazing product by any measure of stick you test it on but the free features are lacking. Bit.ly support would be great because it allows you to track click stats on your posts but sadly if you go free it will not be available. Maybe in future versions when they add more features they might add a few to the free version to say they were thinking of you!
Seesmic
(Free)
Seesmic has focused its efforts on a whole suite of tools that can pull information from many social networking sites and present it to you in an easy to read format. This has been brought to the Android OS in a more minimalistic yet crisp interface. Unlike the iPhone version, the client for Android can only add Twitter usernames and note Facebook profiles and the like. Everything is presented in a straightforward manner at the top of your screen, with the ability to switch from your timeline, replies, messages, and your profile. If the red bar at the top of the page is pressed and you are anywhere on the page but the top, the screen will move to the starting position.
Pros:
Functionality:
When in Seesmic, the ability to make a new post is as easy as pressing the menu button. When composing a tweet the availability attach a picture or video and upload it to tweetphoto.com – a real-time media sharing website – is as simple as taking a picture, the rest is done for you. Attaching your location becomes as easy as pressing the location icon and picking between attaching your location, attaching location map link, or location address. Last but no least is the automatic URL shortener which comes in handy for doing multiple links for one tweet (spam anyone?). The ability to do all this from the composition screen is an awesome feature and clients are quick to adopt it but Seesmic was amongst the first to venture and do it.
Cons:
Plugin Support:
With clients starting to use plugins for their products, this client is lacking. This is also an opportunity for Seesmic to look at what clients like Twidroyd are doing and build and improve an what they like and innovate new ways of using plugins. Who knows, maybe we will finally be able to see

Touiteur
(Paid & Free)
Price: €1.99
Not to be fooled by its French name, this is among the top Twitter clients today. Designed by LevelUp Studio’s it boasts a clean beautiful interface that could rival the iPhones classic user interface (UI). This app does come with a free and paid version so it’s key to note what you would like from this client. The paid version will unlock multiple accounts, 3 widgets for home screen, URL shortening, customization, and viewing webpages and multimedia within the program.
Pros:
User Interface:
Probably the best interface we have seen for Android to date. The sheer simplicity and style draws memories of iPhone’s UI. If you are a fan of the iPhone’s interface then this is the client for you. Everything is laid out at the bottom of the screen and speed depends on how many accounts you have.
Ingenuity:
When clicking on a tweet, the page is expanded and you are given the option to choose a number of options which include reply, links, retweet, message and more. This is a feature definitely worth mentioning because it does not take you away from the tweets at hand and still allows you do what you wish with that tweet unlike other clients who have you view the tweet separate before performing an action.
Cons:
Free Widgets:
The lack of free widgets available to free users is disappointing and should at least include one to satisfy the user who doesn’t want to spend €1.99 on a twitter application.
Verdict:
Twitter is becoming an integral part of people’s social networking portfolio and as such, should have some free (hopefully), premium Android clients. Android supports widgets, most apps give you widgets to simplify the way you access information and take it in and some of these clients have that ability already, so will integrate it later (here is to hoping!). These clients incorporate the average socialite to the power users of twitter and as such they have gained recognition by many. Many will note that some clients only had one or two pros and cons and that is because most features are generic in any client for twitter, these focus on what makes them stand apart. These five described here aren’t the only good ones and more are sure to follow but these are the crème of the crop for now.

Who would have thought that
some corn starch
could be made into
toner transfer paper
? We’re not sure of the advantages (perhaps its cheaper?), but if you have a lot of time or just love to get sticky [Matthew Sager] shows the proper method for making the paper, printing, and then etching a PCB.
If you’re just getting started making PCBs, we recommend you check out these
DIY circuit etching videos
to get a better grasp on the printing and etching steps.

Transparent sheets are also a bit expensive here.– Its just less clutter. I print out the design, iron it a few minutes, throw it into the sink or a bowl with ordinary water to dissolve the paper. And then comes the only step that i have to be carefull about: putting the board into a container of the etching solution for a couple of minutes.@osgeld, LarsFor my printer the magazine paper doesn’t seem to work that well, it seems to deposit too little toner. The glossy photo paper works quite good, and i have a stack of 100 sheets still here from some discounter shop.But if i have some time during the sommer, i just might make myself some of this paper to store for the future (If you do a run of 200 or so papers, it might be worth the hassle)",

To get a ‘thin syrup’ like in the mentioned article, dissolve 4-5 tablespoons of this sweetener in 1 tablespoon of water (adding a little bit of alcohol seems to help the stuff to dissolve well). Let it rest until the solution is totally clear (about 10-15 minutes). Make sure your sweetener contains a lot of maltodextrine, (a little bit of aspartame) but no other additives!",

Couple more tips…Sometimes insufficient toner transfers or spots are missing. I drill a couple of holes in the board and poke matching holes in the paper with a needle. That way I can transfer a second layer if the first one is faint. Also Kapton (heatproof) tape is a god-send, but tiny dots of superglue can work in a pinch to stop the paper from sliding around.",

Chess Table: Physical Interface For Internet Games
|

"Multitouch Hacks"
] |

"chess",
"graphic",
"lcd",
"led",
"projector"
] |
Wanting to get back to playing with actual pieces, [Thomas Pototschnig] built
a chess table that interfaces with the Internet
. The table uses an custom setup to project the board on the frosted surface of the table. Chess moves from your internet opponent are displayed as arrows on the board so you can move the pieces. Your moves are detected by a webcam below the surface as this table actually functions as a multitouch display. From the description, it sounds like the projector was made from a 128×64 graphic LCD display. A 64×64 pixel area is used, with an LED below and a lens above. This works remarkably well. See for yourself after the break.
Want some other options for your chess setup? You can
play against a robot arm
, or if you’ve got 144 square feet of extra space you can build
a really big board
for the occasional game.

What we need in today’s handhelds is LESS resolution. Take a look at the video after the break to see the exciting action that [Bruno Pasquini]
4×4 LED matrix handheld game
delivers. The device is made up of 16 bi-color LEDs, four buttons, and a PIC 16F628. There’s no schematic yet but it looks like there’s no need for shift registers, just some transistors to handle the current load for the rows of each color. We’ve seen a
64-pixel handheld that plays Super Mario Brothers
, but this portable brings a top scrolling racing game with just 25% of that display size.

Passing was cool because your pass was represented by a decimal point that went left -> right across the screen.

Last week, we posted a story about how to
configure speech recognition at a beginner level
. Several of the commenters expressed an interest in doing speech recognition for embedded devices. [Nickolay Shmyrev] volunteered to write some directions for those people. In this article, [Nickolay] will be taking you through the basics of setting up your embedded device with
CMUsphinx
an open source toolkit for speech recognition. He gives programming examples in both C and python. Though we are hosting this, we haven’t set it up and tried it, so please direct any questions you have at [Nickolay] in the comments.
Here we will consider how is it possible to implement speech recognition functions on using
Pocketsphinx library from CMUSphinx project
The advantages of using Pocketsphinx are:
Pocketsphinx is resource-efficient. It can perfectly run on embedded platforms. though it’s not limited to them, you can use pocketsphinx on your desktop/server. Pocketsphinxvhas support for fixed-point only arithmetics so can run without FPU. It is also optimized towards some popular platforms: Blackfin, Maemo, IPhone.
Pocketsphinx supports many languages out-of box. It supports US English, Chinese, French, Russian, German, Dutch and more without need to train anything.
Pocketsphinx is completely free software.
Available bindings for several programming languages are present.
So Pocketsphinx is really the best choice for your speech recognition library.
Before you are going to start with programming speech interfaces there are several things you need to know
Speech recognizers require you to specify the words they will understand (so-called grammar), they will not understand anything else except specified language.
Speech is by nature inaccurate, you need to put this in the corner of speech interface design. Recognizer return you confidence value of the recognized text. Make sure you use this confidence value to reject unreliable results. If recognizer is not confident, try to input the text again, ask for additional information, confirm user intentions.
It’s not the task of the speech recognition library to do sound input. Audio interfaces are often device-specific. You need to record audio in your application and put it in special format – PCM, mono, 8kHz, 16-bit. Doublecheck that. If you have mp3, convert it. If you have audio with 44.1kHz, downsample it.
Let’s start with simple test. Once you installed Pocketsphinx, just run Pocketsphinx_continuous
without any arguments. Wait till
READY…
will appear on terminal then say something. Pocketsphinx will record audio from your microphone and output recognition results.
000000001: hello (-11998485)
You failed to make it recognize hello? Don’t worry, some people find that it’s a hand of fortune who produce the recognition results. Count you are lucky.
Now let’s try to learn how to specify the grammar, the language that Pocketsphinx will recognize.
It’s done using grammar files which are written in
JSGF format
.
This is rather simple human-readable text format, probably it’s better to start with example:
#JSGF V1.0;
grammar goforward;
public <move> = go <direction> <distance> [meter | meters];
<direction>= forward | backward;
<distance>= (one | two | three | four | five | six | seven | eight | nine | ten | twenty)+;
You see it can specify alternatives, repetitions and skips. Basically JSGF describes
finite state automation for the recognizer. The more restrictive your grammar is, the
better will be recognition accuracy. But don’t forget to include all those fillers
and false starts in real grammar. User will not say to the device
“Pizza with pepperoni”
They will say instead
“I want, let me think… three pizzas with pepperoni no… with onions”
And your grammar should cover that. Once you’ve created your grammar, store it as
grammar.jsgf. Also, record audio file at 8khz mono and name it “myrecording.wav”.
Now, let’s do some of the programming. To demonstrate how speech recognition application is created, let’s first try to use Pocketsphinx with Python. Python API is really simple, example is just six lines of code. To recognize speech you need to accomplish 3 steps and here they are:
#!/usr/bin/python
#Step 1, Initialization
import pocketsphinx as ps
decoder = ps.Decoder(jsgf=’/path/to/your/jsgf/grammar.jsgf’,samprate=’8000′)
# Step 2, open the audio file.
fh = open(“myrecording.wav”, “rb”)
nsamp = decoder.decode_raw(fh)
# Step 3, get the result
hyp, uttid, score = decoder.get_hyp()
print “Got result %s %d” % (hyp, score)
Now, let’s do the same with C. It’s not really different from python, just more suitable
for your device.
#include <pocketsphinx.h>
int
main(int argc, char *argv[])
{
ps_decoder_t *ps;
cmd_ln_t *config;
FILE *fh;
char const *hyp, *uttid;
int16 buf[512];
int rv;
int32 score;
/* Initializing of the configuration */
config = cmd_ln_init(NULL, ps_args(), TRUE,
“-samprate”, “8000”,
“-jsgf”, “test.jsgf”,
NULL);
ps = ps_init(config);
/* Open audio file and start feeding it into the decoder */
fh = fopen(“myrecording.wav”, “rb”);
rv = ps_start_utt(ps, “goforward”);
while (!feof(fh)) {
size_t nsamp;
nsamp = fread(buf, 2, 512, fh);
rv = ps_process_raw(ps, buf, nsamp, FALSE, FALSE);
}
rv = ps_end_utt(ps);
/* Get the result and print it */
hyp = ps_get_hyp(ps, &score, &uttid);
if (hyp == NULL)
return 1;
printf(“Recognized: %s with prob %d\n”, hyp, ps_get_prob (ps, NULL));
/* Free the stuff */
fclose(fh);
ps_free(ps);
return 0;
}
On Linux, compile the demo with simple command line:
gcc `pkg-config pocketsphinx –cflags –libs` demo.c -o demo
and run
./demo
If it works, it’s ready to be included into your device. Read more about Pocketsphinx functions
in API guide:
http://cmusphinx.sourceforge.net/api/pocketsphinx/
Once you are done with basic examples, it’s time to build your application using Pocketsphinx.
Free your mind when you design that, don’t just focus on simple commands like “turn on lights”. Modern applications include intelligent logic analysis, continuous dictation support and many more things.
Try to be reasonable, design your interface and grammars, think about user and your speech
application will be successful.
Still don’t believe it will work? Check this video demonstrating pocketsphinx running on Nokia N800(at the top of the post). For more details on Pocketsphinx, CMUSphinx project, speech recognition visit

This is because it’s meant to be two dashes “- -” (I introduced an space between them so they appear as two dashes in the comment).If you don’t understand me (I’m not being as clear as I’d like to), I suggest you look at the pkg-config example in the wikipedia:http://en.wikipedia.org/wiki/Pkg-config",

CubeStormer solves Rubik’s cubes
and it does it quickly! Made entirely out of LEGO, a Mindstorm web camera is used to scan in the cube with four mechanical hands for manipulation. The device is capable of solving a random cube in less than 11 seconds. That’s quite a bit faster than
the last Minstorm solver we saw
, and
the CuBear solver
we are so fond of.
[Thanks Ferdinand]

Try As You Might, Scooty Won’t Fall Over

Scooty is a balancing robot
based around a PIC32. The project is the first iteration in a long road toward a ridable version. The video after the break shows some incredible promise. Scooty is pitted against a large rubber ball. The two roll into each other but Scooty maintains balance thanks to that powerful processor, an inertial sensor, and a range finder.
Scooty versus a ball isn’t really fair to the ball. We’d like to see Scooty versus
the ball balancing robot

There is a number of reasons why it is interesting to get rid of the gears in something like this, because cheap gears have usually game, have big losses and sometimes they are even irreversible. The thing is motors, specially DC motors, are usually meant for really high speeds so it may not be very good for the motors to make them work this way at nearly zero speed. I don’t really know if there exist DC motors meant for low speeds, I don’t think so.Speaking about the idea of building a bigger machine to carry things, to carry people, the best choice would be to use permanent magnet synchronous motors with a large number of pole pairs. They used to be very expensive but they are becoming cheaper with time, the thing is that the ones you can find maybe they are too powerful. Does somebody know what’s the rating of the motors that would be needed?",

[Andres Guzman] is chauffuering himself around the University of Illinois campus thanks to his
wirelessly controlled mountainboard
. He added a brushless motor to drive the rear axel with the help of a chain. Power is provided by a Lithium Iron Phosphate battery which we’ve seen
used in other electric vehicles
due to its lightweight properties. A wireless PlayStation 2 controller operates the motor but steering remains a lean-to-turn system.

Luckily, there was a UIUC grad student named Kieran Levin who saw me and just so happened to be the same person who submitted the Arduino-PS2 interface to the official Arduino website. Thanks to the coincidence, we worked on installing the feature that night and it worked beautifully the next day.To move, you hold L1 and just move the left analog to go 1/2 max speed. Then you can hold R1 and use the right analog stick to go faster to go max speed. To do a 180 tailgrab, you press X O L2 right square X O but I always mess up with the right square.I didn’t add brakes because the gears keep me at a terminal velocity of like 7 to 10 mph. If I was going 15 and I let go of the controls, it would immediately brake and I’d go back to the terminal velocity. My foot is the only brake I need.",

Doing the calculations, you don’t need that much but the problem was that I wanted something with as low of a gear ratio as possible but many brushless motors spin too fast and they guarantee a certain RPM per volt. After weeks of trying to see what makes sense, I said “what the heck…I’ll just get this one”.@ DataC: is this you?http://www.youtube.com/watch?v=WCJek8Oco30@turn.self.off: the board has a very difficult time starting from 0 velocity with any sort of incline but if I have momentum like maybe 5 mph, I can actually skate up a parking garage very quickly without a problem. The motor will get very hot of course; luckily the equipment surrounding it is metal so it’s a very good heat sink.",

Top 10 Features We’d Like To See In Android 3.0

UPDATE:
Hello HaD readers,
Sorry for the delay in updating this. I was on probation while the editors worked with Jason to figure out some things.
Clearly, for my recent debut article, I didn’t research Android OS well enough. After reading each of your comments, I realize that the article fell short of HaD’s and its readers standards for high-quality writing and reporting. Every point I made in the article were problems I noticed in my experience with Android, but I should have done more research on others’ experiences and the capabilities of each version of the OS. To each reader, I am sorry and will do better by you in future posts.
Poor Google. Despite its numerous capabilities with smartphones spread across a variety of carriers, Android still struggles to garner the prestige and positive perceptions of iOS 4. Sales continue to rise, but at the end of the day, the average person is still left lusting for an iPhone. Well, here are 10 features that should be added to Android 3.0 that could change the tide.
1. A no-brainer task manager.
Google says Android doesn’t need a task manager, that it closes programs efficiently without any user-intervention, substandard apps often suck memory dry. Because of this, Android users are forced to download complicated task-managers, each with its own odd UI, and weigh which one works the best. Google, please fess up to the problem and put something in there a computer novice could use. Something with big buttons would be nice.
2. Stable Multitasking
Speaking of crashes, multitasking on Android is a mess. A little optimization here wouldn’t hurt. Better yet, while this may run counter-productive to us power-users, why not release a lite version of Android 3.0 that doesn’t support multitasking? Not every user needs it and lower-end phones would appreciate it
3.
Swype
Google, your Android keyboard sucks. That’s why the fine folks at Swype Inc developed their product. Sure, some of the newer Android phones like the
Droid X
are releasing with it built in, but it would be a boon for the OS to come packaged with this software.
4. IR- sender support
On the hardware side of things, an IR-sender support is a “duh.” Imagine a next generation of remotes running on Android. Better yet, how would you like to control your lights and home-entertainment center with your phone without the sometimes-complicated mess of configuring through a network?
5. Universal pinch-to-zoom
Some apps have it. Some apps don’t. C’mon, this should be standard by now.
6. Folders
Google,
you copied iOS’s homescreen UI
, why not do it again? Many of users have outgrown their limited pages and would like a way to add some organization to their mobile lives.
7. SD-Card support for app-storage
If users are going to download a ton of apps from the Android Market, they need somewhere to put them. Users with rooted phones can already do this, but expandable storage should be standard in app-filled world with insatiable memory lust.
8. Built-in syncing
If the Android is going to succeed as a user-friendly platform, it needs to make it easy for people to add their music, photos, and video to their phones. It’s simple Google. Develop some web-based software and launch it as a beta. You do it for everything else…
9. Standardized UI for all apps
I’m all for artistic interpretation, but the reason so many functional apps get low scores is because they work differently than the rest of the OS. Once again, do what Apple did and come up with better UI guidelines.
10. Better market
Why can’t I queue downloads from the web? That would be awesome. How about a better way to navigate the store from my laptop? Despite the thousands of apps the Android Market hosts, it is stuck with the same problems as Apple’s iOS4. More importantly than any of the above, Google needs to innovate here. Change the way mobile markets work Google and you could win this war.

Instead of forcing you to choose from a popup menu, it makes its best guess then gives you an unobtrusive menu of alternate words to choose from in case it got it wrong. Please, try SlideIT, it’s a superior keyboad and it’s already available.",

Granted a phone with 2GB of ram and a 2ghz ARM A9 dual core would help that too.3) see disclaimer4) Again, linux phone, can’t you write to the IR port from the java environment. If you can, shouldn’t this be a fairly simple app to write, granted it would need IR receive as well so i could make my phone learn codes.5) I thought all apps could use it if they wanted too. How would you like it to just work in all apps? always zoom in/out? or?6&7) sounds good, but again never used it…8) I thought android just let you dump things on the SD card and it figured it out? or do you want an app to ensure format compatibility? aka imagemagik/ffmpeg “andriod” targets.9) So you want google to vet all apps to ensure that they look “nice” before putting them on the store? umm apple store much?10) sounds good. My huge complaint with the iphone app store is while I might like one, i have no idea if it has the apps that i would like on a phone like that. I only have linux computers, so no iTunes for me.

My first experience with an Android device: it was running 1.5 and even for a techy like myself, folders were not intuitive or convenient. They were annoying and no way are folders (as they are implemented now) and the way they work obvious for the average consumer.Regarding what I said about organization: I am a bit OCD and like all my apps alphabetized. I’m not the only one and figuring out the organization is a real pain. All I’m asking for is a bit of simplicity for the next version of Android. Given that Google has announced a revamp of the UI, I’m hoping this will be a part of it.@Cynyr regarding #9, yes. I am not an apple snob. I don’t own an iPhone, but they are #2 in sales for a reason. It is to the benefit of developers and consumers to have a standard of quality. in the ever-ending argument between those who prefer openness vs Apple’s walled-garden, both have important points and Apple’s success and the buzz they generate can’t be ignored.

You can’t have a task killer which kills apps automatically, as that hurts battery life significantly.This is always going to be limited to power users, since knowledge of what program is misbehaving is necessary. I’d prefer a program which better measured which programs are often waking. With well behaving programs, and no task killer, my HTC magic gets almost 4 days even with background data enabled.Also worth noting, you don’t need a task manager. The manage applications screen in settings lets you kill applications.#2 – Crashes? I’m not certain what you are referring to. I’m not sure you have a clear idea either. Multitasking is a fundamental part of android and I don’t believe that this hurts performance or battery life. Don’t forget that android is run on top of the linux kernel, I’m not sure there’s much sense removing multitasking from linux.#3 – Swype owns (for us power users at least). Fair point.#4 – I have a wifi-only (no sim card) G1 I use to control my XBMC box. It owns. Creating a real remote that does similar is a great idea.#5 – Pretty recent feature. Would also like to see it around more. Probably waiting on application developers to update (not really something you can globally apply, just grant as nice an api access as possible)#6 – Folders have been in android since 1.5 or so… iOS copied android on this one.#7 – This is in froyo… Where have you been?#8 – I think that 3.0 does address this somewhat.#9 – There is a standard UI. It is the job of developers to use it properly rather than rolling their own. Not much google can/should do about this.#10 – They demoed this at I/O. It’s in 3.0. Good.",

Obviously, based on my observed battery life, they are wrong.At any rate, I want more direct control over cpu speed/power usage.sd card support – almost everything from the app store installs to the sd card on the xperia. this cant just be a sony trick?",

And no GOOG doesn’t have to do it all nor do they need to tighten their grip on the market place.

We
first wrote
about the MintyBoost back in 2006. Today, Adafruit has created a tutorial for making a
solar powered MintyBoost
. Using a
MintyBoost
, a
solar panel
,
LiPo battery
and a
charger
, they built on their
Solar LiPoly tutorial
. They fed the power tap output of the LiPoly charger into the battery input of the MintyBoost to perform the voltage step-up for USB devices. Based on an
instructable
that used SparkFun parts, this tutorial shows how to use parts that are available from one source. We hear that there will be some evolution of the MintyBoost coming down the line that will including charging capabilities.

Server Enclosure From 22 Rolls Of Tape

"enclosure",
"frame",
"server"
] |
Who needs metal, wood, or acrylic if you are talented with duct tape? This server is housed in a
20-sided enclosure made entirely of duct tape
, 22 rolls of it. A team of seven completed the project after eight build session over the course of about ten days. It’s currently in use at this year’s MillionManLan 9 as confirmed by this
incredibly boring live feed
.
However whimsical, we do appreciate
the build process
. Tubes are rolled until they reach the specified thickness, then cut to length on a chop saw. More sticky stuff is applied to the joints and piece by piece the frame comes together. From the diagram laying off to the side in one of the pictures it looks like they did the smart thing by designing this in CAD before getting their hands dirty sticky.

[Bogdan] has some trouble getting up in the morning. A blaring alarm will do the trick but that’s no way to start the day. To get him through the dark winter months he wanted to try
a sunrise simulator
. He patched into the alarm signal of his bedside clock, intercepting the command from the clock’s microprocessor and using it as an input for his own ATtiny13. From there, the tiny13 gradually brightens a 150W halogen lamp using a triac until his room is as bright as a July morning. A signal is then sent to the alarm clock’s audio amplifier to turn on the audible alarm. He’s got the system set for a 20-minute sunrise so it’s just a matter of programming his alarm 20-minutes early than the ‘I absolutely have to get out of bed now’ time.

That may look like a Ferris wheel but it acts a battery replacement station for small robots. The
marXbot
heads to the battery station when it gets low on juice. Once in the cradle, arms on each side hold the bot in place while the low battery is sucked out and a fresh one from the 15-slot carousel is inserted. The robot doesn’t power down but relies on stored electricity from some large capacitors during the changeover. See it happen after the break.
A while ago we saw
a robot that could plug itself into a wall outlet
. That’s great because the robot doesn’t have to return to a charging station, but it still has to wait for its battery to top off. With a few strategically placed battery stations it’s easy to keep a robot up and running with almost no down time for a battery swap.

Nixie Sudoku

"classic hacks"

"arduino",
"nixie",

"solver",
"sudoku"
] |
[John Sarik] asked himself why a project should only have a handful of Nixie tubes? Without a good answer to his query he went ahead and
built this Sudoku game
using 81 Nixie tubes. There’s not much of a description for his work but here’s how we think things go: The two knobs manipulate a cursor, one for rows and the other for columns, while the keypad is used to input your chosen number. The system is Arduino based and [John’s] linked to his code, schematic, and board layout files on Dropbox. He’s even written a recursive solver which can be seen in the video after the break. Would it be inappropriate to bring this to work and whip it out during some down time?

Get Started With Speech Recognition
|
Rachel Fee
|
[
"how-to"
] |
[
"handsfree",
"software",
"speech",
"voice"
] |
Speech recognition makes it easier for us to be lazy with our devices – or perhaps set up the coolest voice-controlled project around. After the
voice controlled home automation
post, we received a lot of emails asking “how can I make it recognize my voice?”. Whether your project involves a PC or an Android phone, a high-budget, or no budget at all, there is a solution out there. Join us after the break for a complete set of instructions on setting up speech recognition, and some of the best software options out there to meet your needs.
Got a Microphone?
Using a microphone is the only way to get your voice commands to the computer for interpretation. If you’ve got a laptop, you’re probably set to go, as most laptops come with microphones already built in. Not sure? Look for a small hole around the screen or keyboard. It may be labeled, but not always. You can also try checking the list of features in your computer’s manual, or head to your control panel and select “Sound”. In this pop-up window, you’ll find a tab titled “Recording”. If you’ve got a mic installed, it will be listed here.
If you’re using a desktop, you’ll likely have to buy an external microphone. Many webcams include a built-in mic – check the package to make sure. Some newer media keyboards also include a microphone. If this is the case for you, you may have to reposition your keyboard out of confined space to reduce echo. If you’re a PC or Xbox 360 gamer, you might have a headset used to communicate with other players live. This can double as a mic for voice recognition. Don’t have any of these? Head to your nearest store which sells computer accessories – try Best Buy, Future Shop, RadioShack, or your favorite locally-owned retailer. A basic, usable microphone can range from a few dollars to hundreds of dollars. While a six hundred dollar microphone is unnecessary unless you plan to record a studio album with your computer, it might be a good idea to stay away from the cheapest of the cheap – these can often have a choppy and uneven sound of which your computer can not interpret. Generally a headset mic (or gaming headset) is the best way to go, as it sits close to your mouth for minimal interference. Make sure the mic you choose is compatible with your computer’s operating system and has an input your computer uses, and buy away!

Set Up Your Voice Recognition Software
Window 7 or Windows Vista
Voice recognition on either of these operating systems is as easy as a few clicks. With these operating systems, voice commands are thorough and simplistic, allowing you to control everything from form navigation, menu navigation, Office programs, and more. For almost anything you need to do, there is a voice command. To get started, head to the control panel and select “Speech Recognition”.
From here, you can test your microphone, train your computer to understand your individual style of speech, or view and print a reference card containing the commands your computer will understand.
You can also take a tutorial which teaches you the ins and outs of speech recognition in one simple lesson. Select the “Start Speech Recognition” option when you’re ready to get started. This leads you through optimizing your computer’s sound input with positioning tips and speech tests, and guides you through the rest of the configuration in a very user-friendly manner. When you finish the wizard, you’ll be ready to go!
You can refer back to the speech recognition reference card as often as you need to review the commands your computer will understand.
Windows XP
Voice recognition in XP is as easy to set up as it is with the newer Windows operating systems, however, it lacks the vast array of features that Vista and 7 offer. Speech recognition is supported by all Microsoft Office programs, however, only 2002 and 2003 versions are supported. With a version earlier that 2002, or with 2007 or 2010 versions in XP, you’re out of luck, as built in speech recognition is not supported. Otherwise, basic commands are not always supported, and speech recognition cannot be used with all programs. In general, you will have to enable speech recognition specifically for each program with which you wish to use it, and it will not be available in all programs.
Windows XP uses a speech recognition engine which comes with Office XP, though is not always installed by default. Open control panel, and from classic display, select the “speech” option. If you’re using the newer, categorical menu in XP, you’ll have to first select the “Sounds, speech, and audio devices” option.

[Link]
If you see a “speech recognition” tab in “speech properties”, you’re ready to go, as the engine has already been installed.
Youtube: [mickmoose429992]
[Link]
If this option is missing, you’ll need to install it. From the control panel, select the “add or remove programs” option.
Youtube: [mickmoose429992]
[Link]
Find Microsoft Office XP, and select the “change” option. Be careful not to uninstall!
Youtube: [mickmoose429992]
[Link]
Find “features to install”, select the “alternative user input” option, followed by the “speech” option. Select “run from my computer” and click update. This automatically includes speech recognition in all Office programs, and makes the feature available to other programs.

Mac OS X
Apple was one of the first to come out with speech recognition – a crazy idea at the time. This was back in 1993. We’ve come a long way since then, from more fluid, user-friendly controls to the ability to perform almost any action without ever touching your keyboard. Setting up speech recognition in OS X is a breeze. Once you’ve got you mic ready, select “system preferences” from the Apple drop-down menu. From this menu, select the “speech” option.

[Link]
Enabling “Speakable Items” will turn on the default commands, allowing you to perform most basic tasks.
Youtube: [fifedjdomo]
[Link]
Through available options, you can set up your microphone and further customize the use of the program. The set of commands used to control your computer is fully customizable. Pair this with VoiceOver, a program designed for the blind, and you’ll hardly need to touch your computer in order to use it.
Linux Ubuntu
Linux does not currently have a complete solution for speech recognition. Though several projects have been started, none have been finished. There are several pieces of software that can perform some of the speech recognition tasks that Windows or Mac can accomplish, but nowhere near as thoroughly or easily. There is also no proprietary software for speech recognition with Linux, however, there are some partially-completed open source solutions for Ubuntu. Julius Speech Recognition engine is one of these utilities – a program used to interpret and execute a set of pre-determined voice commands. Detailed instructions for installation can be found
[here]
.
Youtube: [jgraves1141]
[Link]
Documentation on the installation and use of Julius is
very
limited due to the fact that the program is not completely finished, so you may not want to attempt an install unless you are completely comfortable with the use of Linux. The Julius package available for download contains two parts – an installer, and the program. First run the installer which will take you through the installation of Julius.
Another great solution is to use a Windows-based program such as Dragon NatuallySpeaking in combination WineHQ, however, there are lapses in fluidity that often have to be worked-around. For example, in some cases, a basic paragraph must be narrated to Dragon’s text editor and then copy-pasted into the appropriate location rather than transcribed directly to the appropriate program.

Top Third Party Proprietary Software
If you have an older operating system, or simply don’t like the speech recognition software included with your operating system, a third party program may be what you need. There are dozens of free and paid speech recognitions out there, customizable, non-customizable, open source, for business, for personal use, and more. With so many options, you’re sure to find exactly what you want at a cost you can afford. Some of the most popular:
Dragon NaturallySpeaking
Dragon is a name that pops up over and over when searching for speech recognition software. Made for PC, it’s highly regarded for its speed, accuracy, ease of use, and large number of commands. The basic version of Dragon for home use is around $100 US, though many versions are available with more specific features, such as packages for medical or legal offices. These packages can cost over a $1000 US, though are unnecessary for the basic user. Dragon NaturallySpeaking software packages also include a mic, so you won’t have to try and find your own. In addition to Windows, many users have claimed great success with Dragon in combination with WineHQ for Ubuntu.

MacSpeech Dictate
MacSpeech is produced by the same makers as Dragon NaturallySpeaking. It was built from the ground up, rather than being ported, so it is free of the bugs that typically come with adapted software. Similar to Dragon, MacSpeech offers not only dictation recognition, but customizable speech commands as well, and includes a mic in the package. Also following the Dragon theme, medical and legal versions are available, as well as an international edition which supports Italian, French, and German in addition to English. These speech recognition tools for Mac range from $150 US to $600 US.

IBM ViaVoice
IBM’s ViaVoice recognition software is designed primarily for use with small mobile devices and vehicle automation systems, though it’s quite highly regarded amongst computer users as well. ViaVoice offers text-to-speech in addition to voice recognition. The command library is intuitive, and the user does not need to stick to a standard set of commands to make use of all the features – the program can interpret most commands as they are given. The speech library contains over 200 thousand words; far more than the average person’s vocabulary. Supported by IBM ViaVoice, in addition to many mobile OS’s, are standard Windows and Mac operating systems.
Third Party Open Source and Free Software
Open source or free voice recognition software that works well is extremely difficult to find – there is really no winner in the open source race for free voice software. In fact, there is hardly a race at all. Numerous open source Linux projects have been started, but due to the extreme scale, none have been finished. Below is a project you can contribute to in order to get the ball rolling on some great open source speech recognition software, as well as a toolkit for your own uses.
VoxForge
VoxForge is a project working to compile a collection of transcribed speech for use with both open source and free voice recognition engines. Upon the completion of this project, free open source speech recognition programs should be given the jumpstart to increase significantly. If you’d like to help the project, you can visit the VoxForge website

CMUSphinx
Sphinx is now on version 4 (Sphinx 4). Perhaps the most (or only) popular open source speech recognition tool, Sphinx is licensed under BSD and is written in Java. Sphinx also offers a mobile version called “PocketSphinx”. This may be more useful for developers than the average user, but it’s one of the only solutions available, not to mention a versatile and thorough one. It does not come ready to go out of the box, but rather is a tool that can be utilized by developers. It certainly needs some work before it’s ready to go.

How to Install CMUSphinx
Setting up CMUSphinx is not the easiest task, but it is likely to pay off with a great product. This install needs to be done manually.
Before you get started, you’ll need a few things – Perl, in order to run the scripts, and a C complier for the source code. Perl is free, and included with most Linux distributions. GCC (GNU Compiler Collection) is a good tool for the C portion of the source code. A word alignment program is also necessary – CMU suggests “Sclite”, a tool specifically used for speech recognition programs.
The databases you will need are available
[here]
. You’ll need either AN4 or RM1. Next, you’ll need to set up the trainer. A trainer helps your computer interpret your commands. Set up the tutorial – this will include copying the scripts to the proper area. The decoder is next. Though you can pick any decoder you choose, CMU describes the installation with Sphinx 3, and encourages you to perform your testing with Sphinx 3. Once you have all of the appropriate files in the correct directory, it’s time to compile, and set up the tutorial. Perform a training run, and finally, perform a decode. This set-up is extremely complicated, as is likely best left to the professionals – certainly not something for most average users.
Full instructions can be found on the Carnegie Mellon University’s Sphinx website
[here]
.
This demo shows Sphinx in action:

You’re Ready To Go!
Once you’ve got your mic functional and in-place, as your speech software set up and configured, you’ll be ready to get started! Sit back and get talkin’!

I was rather impressed. For home automation stuff I would definitely recommend a small dictionary that you make. I dunno if its possible, but the nicest option, in my opinion, would be if you could switch out dictionaries at run time so you can have context specific word lists to keep the accuracy near 100%",

So you could say tv 5 and the app could send “programname 5” to change the channel. I even think the app i had needed a start word before it would do anything. i used “computer” then i would say the comand. not sure if dragon has the same type of features.

Meter Clock

This
analog meter clock
was built by [Len Bayles]. Its 3 meters are controlled by an AT89c2051. The circuit itself is very simple, and available on the site. The meters are powered from a DAC, with a quad amp in between to keep the meter from drawing too much current.

Control A TV With GLCD Commands

This hack lets you
use a TV in place of a graphic LCD screen
. But we like to think of this less as a replacement for a GLCD and more of a simple way to get your information onto a television. A PIC 18F452 acts as a translator between the GLCD parallel inputs and a composite video output. There are some malformed image links on the page which we’ve fixed and linked to after to the break so that you can take a look at the schematic, component layout, and PCB artwork. The assembler code and hex file are available for download but you’ll need to register to get access to them.
Working image links:
Schematic
Component Layout
PCB Artwork

Watch out,
these sunglasses
are actually a
head mounted display
. [Staffan] says he’s wanted dataglasses since ’95, but whats currently out there makes the user look ridiculous, and we
have to agree
. While his forum posts are a little lacking in detail, he’s promised us more info soon. And for now lets us know at least the resolution, well sort of: Its either 480×1280 or 480x427x3,
you can be the judge
. Update: [Staffan] has clarified “The resolution is 480*1280 true pixels. It is accomplished by spanning the screen across two Kopin CyberDisplay VGA modules.”
Regardless, [Staffan] is looking for help perfecting the glasses, with what in particular we’re not sure, but the project looks promising and we hope he keeps up the good work.

All doable, but then you start running into patent walls.b) No damaged is accrued by the eye – liability is ridiculous, which means our only hope is lotsa no-name asian knockoffs who can vanish at the first lawsuitc) we need pixel by pixel brightness control, color control and muxing tricks alone won’t pull this off.

Building An Electric Kart

"kart"

[Henry Herndon] is working on
building an electric kart
, mostly with surplus parts. He’s got
some experience with electric vehicles
but that doesn’t mean the build is going without a hitch. So far he’s come up with a way to
make the peculiar motor shaft play nicely
with his rig but once everything was put together he had trouble with the chain coming off of the cogs.
We know there’s a lot of links here so far but just a couple more: [Henry] took some shots of
the kart chassis
before adding the motor, and just for fun, take a look at
his scotch tape dispenser
. When you’re done clicking on those join us after the break for some test drive footage.

Leapster Explorer Continues The Didj Tradition

"Didj",
"explorer",
"Leapfrog",
"leapster"
] |
Leapfrog has a new device out called the Leapster Explorer. [The Moogle] has been
poking around the insides
and he patched into the serial bus to get
USB host mode
running. Because the same cartridge interface is used for the Didj and the Explorer, tools like
the DJHI
should continue to work. The $70 price tag makes this a no-brainer if you interested in doing some portable hacking. We’ve seen promising Didj hacks such as
OpenGL
and
Video out
, hopefully the new hardware will help advance the cause.

Stepping Beyond The Ethernet Shield

"enc28j60",
"ethernet",
"nic"
] |
We’ve said it time and again, the Arduino is a prototyping platform. In that spirit, [Doug Jackson] shows you how to conserve the expensive Arduino board and Ethernet shield by
building your own Arduino Ethernet module
. You may remember the ENC28j60 as
a NIC for your microcontrollers
. [Doug’s] board makes use of that chip and adds an ATmega168 with a crystal, power regulator, breakout pins, and even a few DIP switches which can come in quite handy.

I’m, simply, saying that as you start to broaden the type of content you post here, it will become harder and harder for people to sort through all of the stuff they consider fluff to find the articles they, actually, want to read.

For example, years ago there was a Grafiti Projector Webcam tracking post (dont remember exactly which one) but it was awesome, informative and open source. I would love to see more of those kind. Then there was a post about secure thumbdrive which was vague and not even a hack(basically and advertisment). Anyway, what I’m meaning to say is that it will all depend on the writers. If they tackle detailed mods and programing Im all the more for it, and to tell you the truth if they dont, I’ll just not read the post.

Additionally, its lose-lose situation Hackaday cannot fulfill desires of everybody so somebody is going to get offended and its their choice. SO WHAT if I have to scroll a little more just to skip over a post that I don’t want to read.

Like how a fire-hydrant works, how a coal mine work, how a jet-turbine works to even how a match works and are made. Typically each subject is two are three pages and lots of diagrams.The book could contain small snippets of the best way to do something. A couple of pages on how to analyze data. Small but useful things and keep the subjects to no more then three pages. There could be a couple of tutorials. The book could contain things that or easy and also horribly complex.Seriously, I would love to have couple of Books on my shelf and that I could handle and look up stuff.",

There are a lot of awkward programs out there, and sometimes all it takes is a good how to. I had a hard time learning how to program PICs with the MPLAB IDE for example. Using assembly I was fine, but when I moved on to C I had difficulties. It turns out certain bits were set by default I didn’t know about.Anyways I think it would be best if we hold our criticism until after they’ve had a chance to demonstrate their potential.",

"content": "I have also been reading Hackaday for a really long time. I read it because it not afraid to be technical and it had a nice, small, vibrant community. I even wrote for Hackaday for about 6 months. When I was brought on, Eliot (the former editor) was explicit to all the readers and writers about the change in content. Everyone still bitched and moaned which I understand because people who have been reading and commenting for a long time feel strongly attached to the original community and purpose.The thing that people forget is that Hackaday is essentially now a business. Hackaday even has a parent company, Mahalo, which honestly seems kind of sketchy because I have no idea what they actually do… The point is, these writers get paid and someone high up the ladder gets paid. And although I doubt any of them actually live off the money, I know I never could have, the money is a big part of keeping this alive. All this being said, don’t be so surprised and distraught when you see Hackaday start to shift it’s focus to a more mainstream crowd, how else are they supposed to stay alive? Hackaday won’t ever be the same, and some may say it is dead, but as long as you people are still out there creating good content, Hackaday won’t be turning it down. I assure you.It is getting old and I think it is an amazing thing that it has kept such integrity for this long. I just think it is ridiculous to demand that they must weigh your comments heavier just because you were here first. Business works on democratic principles. I guess all I am really trying to say is that Hackaday is no longer a small community run purely on sweat and free time, there are money interests somewhere in the mix, and that is okay because what most people probably don’t know is that Hackaday would not have survived without the shift in content to appease more readers. I know it is tough to watch it change but thus is life, get over it.Wow this thread is long, no one will read this. I don’t even know why I wrote it.",

Even if your site is a complete fail you can easily get this back from ads.I have site chains where I pay for content writers from india 1$ for 30-40 quality articles :DI doubt this site would be so monnie oriented like many other tardshit sites such as digg.com so stop whining.Nah anyways I just wanted to say it would be better keeping it HARDWARE focused not SOFTWARE. I only want to see useful hardware hacks here and possibly free energy shit in the future.I very much like that the articles are so detailed that you can build almost everything at home from scratch.Just some ideas for the future:-make a standard file upload for content writers who can attach stuff to the site-make some field where we can dl the PCBs sprint layout files and if there isn't any available then get a guy to make them",

Wireless controller, more powerful custom-made motors, stronger frame, and with a name like
DeathBlades
, we can’t think of a single reason why you would prefer
heel treads
,
well everyone was
young at one time
.
[Charleg] has been testing out a
slightly new frame
, despite having only half the motors necessary, and is getting great results hitting around 23Wh/mi. If you’re looking to build your own, his blog has
a post
for
nearly every
aspect
of the design
.

Touch Screen Using Range Sensors
|
Mike Szczys
|
[
"Multitouch Hacks"
] |
[
"arduino",
"flash",
"range finder",
"touch",
"ultrasonic"
] |
This
touch screen relies on measurements from two range finders
to track your finger as you press buttons. [James Alliban] put this together as his first Arduino project. We’re familiar with [James’] background because of his informative
augmented reality business card
. As the Arduino picks up data from the range finder it sends it to a Flash script that is running on the PC.
As we watched the video after the break a lot of questions came to mind. What kind of angle do these Ping sensors have? Will there be interference problems if they were placed perpendicular with each other? Would you get more accurate data if they were not both on the top of the screen? For now this is just a preliminary experiment, but we like the concept and may give it a try ourselves.

Heel Treads Make Shoes Go

Motorized treads
as a replacement for the heel of your shoe? Okay, remember how
The Jetsons
had moving sidewalks everywhere so you wouldn’t have to walk at all? Well, there’s a much more efficient way to do it and Treadway Mobility seems to have figured it out. In the video after the break you can see several of their prototype units zipping the wearer around quite happily. We think the best part is that with the tread locked in place you can stand and walk like normal, assuming you don’t feel like you have a block of concrete attached to each foot. Maybe the real question is which is more geeky, this or
the power lace shoes
?

[Debraj Deb] put together a current monitoring
device that interfaces with the circuit box
at his house. The system is controlled by a PIC 18F4520 and uses an LM358 Op-Amp to rectify the AC signal, as well as an MCP6S21 for range adjustments for detecting both high or low current loads. The data displayed on a character LCD includes average,
RMS
, and peak current. For now the data is saved to an EEPROM and can be dumped using a serial connection but [Debraj] plans to add a GSM modem so he can send energy use data to his cell phone.
[Thanks Ganesh]

The only danger is installing it in the first place, since the main input buss is exposed and not able to be switched off before the ‘main’ breaker. Common sense dictates that if you don’t know about the dangers inside a circuit breaker box, then you shouldn’t mess with it. Also don’t stick forks into outlets like I did when I was a kid, it made me a bitter old man.I have a whole bag of those pickup coils (fleabay) which the to-be-sensed wire passes thru, I wanted to monitor every circuit leg to see precise info on where the energy was being consumed. But via experimentation, I think I came to the conclusion those are best coupled to a smart energy monitor chip (microchip makes some) which can do the calculations very accurately without needing to know a ton of AC math. (which is hardcore, at least for me) You run into issues with high frequency devices like CFLs and SMPS’s, but the chip takes care of that. Now I have the energy mon chips(samples), but they require quite a few external components, so still shelved.Props to this guy that rolled his own! And the adjustable gain feature is very smart, that’s one of those things you think of after you made it and it isn’t precise as you needed. Great project, wish it had more details.",

The gauge of wire coming into the main breaker is usually 2/0 or 4/0 AWG and most of the current sensors like coils or hall devices are not equipped for that.There is also no place inside a service panel to attach such a device and have it be safe. The only place that is exposed for attachment is before the main breaker disconnect. You do not want to be attaching a device to a line that cannot be turned off except by pulling the meter.Retail devices that do it use a split core and special mounting boxes that have a disconnect then the sensor then the main breakers. Just putting a sensor in a breaker box before the disconnect is foolish.http://www.controldepot.net/splitcorelooppoweredcurrentsensorw4-20maoutput0-1000-1500-200amps.aspx",

But I plan to put the schematic on paper, so it might benefit others. But as such, the hardware is simple.Rough calibration: –every appliance that we use carry the power rating. My water heater is rated for 2KW and hence, it will draw a current of (2000/230) = 8.7Amps. And the RMS reading that I get on my LCD is almost 169. Hence 169 = 8.7Amps. This is a quick calibration, but very rough indeed.Correct calibration: –Get a standard meter and measure the current drawn in the mains, and the display on LCD. Try with different euipment — water heater (resistive), laptop charger (capacitor current), lamp ballast (inductive)…Safety and isolation: –I used a current transformer to measure the current. The output of CT is isolated and hence safe. I am not measuring the voltage, I assume it to be 230V constant. Even if I had to measure the voltage, I will use a tranfomer to isolate the mains. I usually work on hig voltage circuit and hence aware of the risks involved.Another puspose of the project: –My wife forgets to switch off the water heater. So, it keeps running for 1/2 hour and that increases my electricity bill. I will connect a buzzer on the board which will beep loudly if the heater is ON > 10min (which is sufficient).current transformer: –I got is from a scrap dealer. But in India, you can get a new one for US$2 ~6, which will give a decent output upto 18Amps (230V * 18A = 4K, big power!!). My CT has a resistance of 330ohms.MSP6S21: –Its a typo, the real part number is MCP6S21, a programmable gain amplifier from microchip>>http://www.microchip.com/wwwproducts/Devices.aspx?dDocName=en010483Can be insterfaced to uC thro SPI and provides different gain from 1 to 32..",

Depending on how far you are from the pole pig, the gauge of the wire and just what exactly you do to short it, you could be on the receiving end of several thousand Amperes of current.Yes, you’re using current transformers. Good for you. These things can and do fail. Insulation fails. You could very well end up on the receiving end of these multi-thousand Amps of current hitting your circuit. I’m far less worried about the insulation failing as I would be of accidentally touching something while slipping the CT on. Best to disconnect the service before attaching this thing, or using split-core CTs as someone else mentioned.“Real Power” measurement is tricky, even for us pros. For hobby stuff measuring your current and voltage simultaneously and multiplying to get instantaneous power isn’t always easy, and if you want to keep yourself isolated presents some interesting design challenges. Complex harmonics can also present interesting waveforms to measure, which mean you’ve got to increase your sample rate to even see them. There’s lots of information on this out there if you’re curious: the term “crest factor” is a good starting point. For most of us though we don’t need to be quite so precise, so a peak-reading S&H and some fudge factors will do just fine.Very nice project. I’ve mean meaning to do something like this with my own house.",

One of them is not correct, which one is it?I think this project is as simple as it gets, the best next thing to improve is to measure the voltage to account for active energy only.

The transformer is split phase so it has 3 wires . 2 of the wires are out of phase and provide 110VAC each. The 3rd wire is neutral . Measuring from phase to phase wire gets you 220VAC and from either wire to neutral is 110VAC.From the transformer on the pole it goes directly into a meter base. Inside the meter base it connects directly to the meter there is no fuse or breaker in the path.Picture with connections labeled.http://www.selfhelpandmore.com/images/home-wiring-usa/main-dwelling/meter-new-service-panel/100aoverheadmeterbaselineload.jpgNotice that once the meter is installed there is nothing breaking the connection to inside the home.The power goes from there to the service panel inside.http://rei-specialist.com/yahoo_site_admin/assets/images/breakerbox.210164130.jpgThere is nowhere to tap it before the breaker without the risk of fire if what you do fails. And if it does home insurance will not pay for the damage. Electrical code in the usa specifies that only a licensed electrician can alter the wires on the input side of the main disconnect.Even though I am an EE when I rewired my home I could install my own disconnect after the meter but had to have the power company make the connection to that because I was not allowed to do it. So on the home I have 2 disconnects. One on the outside right after the meter and one on the service panel inside. But most homes are not wired like that. The only thing stopping 200A + current from flowing if something fails or a mistake is made is the wire size.",

[Derek] puts the “hack” into the word shack. We really enjoyed his “little yellow house” videos and
shared them with you
. After that, we discovered that he has published a book. No, he didn’t
have
it published,
he
published it. This guy is DIY through and through. “
Humble Homes, Simple Shacks, Cozy Cottages, Ramshackle Retreats, Funky Forts (And Whatever The Heck Else We Could Squeeze In Here)
” was hand produced by [Derek] himself. It includes plans for a number of different shacks, ranging in size from too tiny for an adult to large enough to house a family. Not all of them are completely practical, but there are several that would make perfect workshops.
We got a copy of the book and have been getting lost in the seemingly endless illustrations. We highly recommend that you do so as well, if you have any interest in building from scrap, or unique structures. Even if you aren’t that interested in construction, the eclectic style and humorous rants about waste might just be enough to keep this book around.

Considering how hackable the Nexus One is already, we can only imagine a whole new host of interesting things thanks to
Ubuntu running on the device
. [Max Lee] set his heart out on getting not just Ubuntu on the Nexus One, but also Debian, and he wrote a perfect install guide to help out those wanting to give it a shot.
He cheated a little bit by having Ubuntu run in the background while the X11 interface is simply VNCed, but he still did an awesome job with
plenty of pictures and details
to help you achieve Ubuntu on your Nexus One.

Multi-layer Display Uses Water Instead Of Screen

This
multi-layer display uses droplets of water
as a projection medium. This way, several different projected areas can be seen for a not-quite-3D layering effect. The trick is in syncing up all aspects of the apparatus. There are three manifolds, each with 50 stainless steel needles for water drop production. A solenoid valve actuates the drops, a camera images them mid-air, and a computer syncs the images of the dots with a projector. In the video after the break you can see the SIGGRAPH 2010 presentation that includes a description of the process as well as action shots including a 3-layer version of Tetris.

A student team at University of Massachusetts have built this
wireless face tracking camera system
. Using a small 2-axis motorized camera meant to be mounted on model airplanes, an arduino, and some custom software, they can track faces and keep them in frame in real-time. This is pretty cool, but maybe
not quite as groundbreaking
as they make it sound. We think it is pretty awesome though. You can download the software and schematics on their site.

In this video, you can see it continue to track his head at much more extreme angles (although I don’t think he got to 90 degrees). So, at least their face-tracking is good.

[Travers Buda] is giving new life to his abandoned childhood toys. He cracked open a set of Family Radio Services radios he had received for a birthday which work up to 2 kilometers apart. With just a bit of extra circuitry he was able to
get them to act as wireless modems
. The system functions but it looks like it would benefit from some more refinement, including error correction. In the end [Travers] manages to send and receive ASCII based messages at a whopping baud rate of 10.

Got my tech and general licenses a couple months ago, only took a couple hours of brushing up on theory and laws, followed by a $15 fee and a couple of simple multiple-choice tests.Why did I mention that? FRS operates at around 467mHz, the closest legal band is 70cm, or 420-450mHz. Not sure what type of local oscillator these radios use (never had one to play with), but it should be possible to replace or modify the LO circuit, drop it into that band, and mess around legally (provided you’re licensed, you only need tech but general is easy enough to get)…Up the power to 5 watts or so (also relatively easy), and now you’ve got a usable system for RTTY based on ubiquitous, off-the-shelf hardware (except for the MCU, but they’re cheap enough)…",

The new rules also permit the transmission of brief text messages. The maximum transmission time must not exceed 1 second, and the minimum time before the next data transmission must be not less than 30 seconds.Only those FRS radios that the FCC has specifically certified for such data operation may actually transmit data. FRS rules continue to prohibit the attachment of any device to an FRS radio for which use that radio has not been certified by the FCC. ”Data IS allowed in FRS, but only for FCC approved devices, like the Garmin. It restricts your ability to ‘add’ data services to an existing FRS transmitter though.",

Think the swirling glow of a Decatron is cool but don’t want to deal with the voltage issues? [Osgeld] sidestepped the problem by developing
a fake Decatron
. Admiral Nelson (Captain Morgan’s cheaper cousin) provided the enclosure in the form of an airplane sized liquor bottle. The LEDs are common-something (not sure if it’s anode or cathode) so they end up being individually addressable through the mess of wires coming out the end. This will greatly simplify that
kitchen timer
we’ve been meaning to build. See the blinking lights go around and around after the break.

Anyone who says this isn’t a “hack” has likely never built a piece of hardware in their life and subsequently can’t appreciate the work involved in making something even relatively simple (a chain of LEDs) look neat and *professional*. You clearly took effort to get the details right: the size and shape of the “envelope” (mini-booze bottle was an inspired choice), the black Bakelite lookalike base, orangish-red LEDs to mimic neon, etc.So I’m curious, did you realize you were making it a “duodecatron” (base 12) instead of decatron (base 10)? Obviously when just being used as a visual display it doesn’t matter, but people might be interested to learn that dekatrons actually *did* something useful (counting) rather than just spin and look cool… ;-)@mjrippe: Dekatron is a specific brand name of decatrons, so yeah, you really have no idea what you’re talking about.",

Mini Racing Cabinet

Here’s another
small arcade cabinet
. This time around it’s the racing simulator Daytona USA. [Pocket_lucho’s]
cabinet work has been featured before
and he did some fine work with the control interface on this build. The wheel is from the controller of an RC car and the gear lever from a heavily used toy. He fashioned two pedals using gate hinges and a couple of leaf switches. The guts pack quite a punch with a mini ITX motherboard running the show. This will look great next to
Ms. Pac-Man
. Check out the video after the break.

[Diego Stocco] makes music with instruments he assembled. For instance, his Bassoforte uses piano keys, the neck and strings from an electric bass, and what look like some cymbals. Throw in a hammer from that piano and a double bass bow (plus heavy use of audio software) and he’s in business. Big business actually, his work has been in video games such as The Conduit and in feature films like Sherlock Holmes where he worked with Hans Zimmer. Bassoforte isn’t his only invention, he’s got several more including
the Experibass
string family on one instrument, the
Light Controlled Oscillator
, and
sand music
using the fine aggregate along with some piezoelectric film transducers.

In this instructible, [wkter] takes us through the process of
running a Nokia 3310 LCD display using an ATmega8
. This instructible isn’t a beginners project as he assumes you already have a strong understanding of how to work with these components and their programming languages. He is very thorough with information though, providing datasheets, pinout diagrams, and source code. Once you get this down, you could go a little further and make
Conway’s game of life

30 Mph Electric Mountain Bike

A 48 volt power house pushes this mountain bike at speeds up to 30Mph. That’s a bit of a boost from many off the shelf E-bikes. [Jennifer Holt] wanted speed, and to retain the off road capabilities of her bike, so she
made a custom one
. As you can see in the video, this thing gets going fast and hills are no problem. She says that it will toss you off if you slam the throttle, and we believe her. We know some of you will insist on chiding her because she’s not wearing a helmet in those videos. She did manage to break her elbow offroading in the video after the break. That part is edited out though.

Back to the Future Part 2 provided a glimpse of a future that included hover boards and holographic advertisements. But you don’t have to wait until 2015 to get your hands on at least some of the technology. [Blake Bevin] has produced a pair of
shoes with power laces
as seen in the film. Of course present day technology doesn’t allow him to make the mechanical parts disappear so you’ll have to deal with two servo motors and an Arduino hanging off of your heels. But hey, at least you won’t have to tie your own shoes like some 20th century peasant. No word on
using these for a little theme music
as you walk around but maybe that’s something from the more distant future.

This is where my real stroke of genius becomes apparent.Fit the door with a CRANK attached to a geared motor attached to a generator, which in turn is wired to the window motor. When you want to raise or lower your window, you simply turn the crank!Awesome, huh? And it’s “green” too, because you don’t burden the alternator (and hence the engine) with the load.I would argue that from a health standpoint, it might even be good for you. Turning the generator crank is the least you should do to get access to the Burger King drive-through intercom.",

garage door indicator
tells him if the door is open or closed. He was inspired by
the hack from last September
but wanted to make it wireless. The setup uses an RF transmitter/receiver pair from Sparkfun, each controlled by an ATtiny13 microcontroller. We found his battle with RF interference from other devices to be interesting. Working out those bugs made for a great learning experience.

Reverse Engineering An RF Clicker

[Travis Goodspeed] has
pulled apart a TurningPoint response card
, which is an RF device for answering quizzes, attendance checks, and casting votes in a classroom setting. After tearing it apart, he set out to reverse engineer it and managed to get quite a lot done. At this point he can spoof cards, so he could fake his or several people’s attendance. He can also sniff the packets as they are sent, opening up a plethora of opportunities to mischief. The one that was mentioned in the tip line was to simply repeat the answer that was most often sent for the quizzes. The writeup is very detailed and has great pictures. Good job [Travis].

An ox was on display, and the villagers were invited to guess the animal’s weight after it was slaughtered and dressed. Nearly 800 gave it a go and, not surprisingly, not one hit the exact mark: 1,198 pounds. Astonishingly, however, the mean of those 800 guesses came close — very close indeed.

Mostly, the only way for an average hacker to get these clickers is by theft or “borrowing” from a classroom’s set.From a teacher’s point of view, while I’m happy to see some students thinking, hacking and doing the math and programming needed for this project, I sure hate the idea of instructional funding possibly being abused since it’s so hard to come by.",

[HP Friedrichs] wrote in to tell us about an
upcoming book titled Marvelous Magnetic Machines
. Ordinarily, we skip over promotional hype. After watching his promo video though, we couldn’t help but share. We want a copy of this book. In this book you’ll find details on how to build a number of different motors from scrap. You can see several variations in the promo video. He also notes that the music was created by himself and some friends a few years ago. If [H.P. Friedrichs] sounds familiar, it is because he’s been
sending us fantastic project
s since at least 2006.

While
hacking a wireless presenter
doesn’t sound like something worthwhile or interesting, [Niels Teusink] demonstrates that these little devices often are a lot more powerful than we give them credit.
With an Arduino, plenty of research, and some heavy sniffing of a wireless presenter’s SPI and then wireless interface [Niels] is able to emulate an entire keyboard. Sending commands as harmless as “next slide” to the devastating “[Win+R] Format C:”. Hopefully anyone planning such a project at the next Apple or Microsoft keynote just intends some gentle fun.

The person causing the pain may suffer there own PIA if discovered and his toy is place in there “A” forcefully.As far as I know the dongle used for wireless devices, other than blue tooth headsets, are receivers only not xceivers,so no data can be gotten from the computer with which the dongle is attached to.D_",

First of all, you can copy and paste individual characters from some other document to form any input (assuming the characters you need exist in a document somewhere, alternatively you could use the Character Map). This might take a while for lots of input but perhaps you could enter a “tinyurl” or something quick enough to cause trouble. You can cause plenty of problems with regular mouse actions as well (delete files and then empty the recycle bin; delete important system files; cause general mayhem). It’s naïve to think that it’s safe to let the public take over *any* input, to the computer you’re using publicly in front of hundreds or thousands of people… it’s just too tempting.",

I run it in an XP VM, which works well enough; I don’t really push it to the limits of it’s potential (I’m usually just using it to sniff I2C and UART communications, plus confirm that hardware PWM’s are acting like they’re supposed to), but it’s great for what I need it for. The software actually got updated relatively recently, which is nice — the older version, while it worked, was a little on the buggy side.There are alternatives that have come out since I purchased mine; a few open source/hardware ones that honestly I’d probably prefer, that may work better or worse, and may be cheaper, but I haven’t worked with any of them so I can’t speak to their quality.

[Spiritplumber] has been sending us updates on a promising project he’s working on called RobotsEverywhere. We’re not completely sure if that name covers the project itself, or just the name of
his group that is selling robots
(and
giving us schematics and source code
). Either way, they have some really cool stuff. The really cool part about many of the bots is that they are using
Android phones as their brains
and they use the same system on land, air, and water. There’s tons of information sprinkled around the site and the Wiki, take a few minutes and look around.

Hard Drive Destruction Plan

[youtube=http://www.youtube.com/watch?v=jhfF2Et77aw]
[Wolf] emailed us to show us his
Self destructing Hard Drive
tutorial. He’s using thermite, like
we did
, but he’s put a little more effort into the delivery system. In the video, you can see a huge spray molten iron. This is because his “jet”, the block of wood hollowed out to focus the thermite on to the hard drive didn’t hold a seal at the top. Not too bad for try #1. He could probably build this to be more contained, but even then it will most likely turn into “entire self destructing office” if it were to actually be used. A little common sense goes a long way here folks, this is molten metal and is extremely hot and dangerous.

There may be legal ramifications if a destruct method harms person or property, so thermite may be out of the picture for self-destructing hard drive.Nice fireworks to be viewing on the 4th of July though.

A small-scale thermite reaction like this is far too insignificant to have any effect on the environment.-It’s only destruction of evidence if it’s in the possession of authorities and they recognize that it has some evidentiary value. They can’t just call something evidence and charge you with its destruction unless they’ve had an opportunity to examine it and prove that it contains incriminating data. Unless they had a warrant specifically calling for the hard drive and the specifics of the data on that hard drive, you would merely be destroying your own property – which you have every right to do. (That’s the way it’s SUPPOSED to work, of course. Judges are notoriously sympathetic to prosecutors, so you might get screwed over anyway.)-It’s not arson unless it fits one of the following parameters: if it were someone else’s property, if you had insurance on it and tried to collect, or if you did it in a way that harmed somebody else and you should have known it would harm somebody else. (That last one includes a slough of highly-subjective culpability factors. Good luck convincing a judge you weren’t negligent if you have to defend yourself in court.)-As always, those of you who piss and moan about the quality of links on HaD can suck a big bag of dicks. If you don’t like the links, submit your own or stop visiting the site. The links can only be as good as the links they find, and the rest of us don’t want to read your unproductive, self-righteous bitching. Learn to be appreciative of the hard work the HaD crew puts in, and keep your ignorant, self-important criticism to yourself.",

Calibrate Those Instruments

This tip was a pleasant surprise on a Sunday morning.
This site explains cheap and relatively easy ways of calibrating
the instruments we hold so dear. Not only how, but when and why. Included are instructions on calibrating Voltage (DC and AC), frequency, RF and more.
[thanks Jan]

[Koala] was worried his
pseudo smart card trick
wouldn’t be considered a HackaDay worthy. We’re more worried the internet police will find this article and have us all tarred and feathered.
Jokes aside, it seems Laundromat owners sure aren’t learning. Long story short, using a Bus Pirate and a
few techniques
we’ve
seen before
for smart card hacking [Koala] is able to write whatever amount he needs onto his pseudo smart card; thus giving him a
free load of laundry

Even were that exploit to be known inside the security community.What has happened here is no different.This, is enabling, and abetting the publicationof a 0day against certain revenue tracking machines.A hack, is a hack. and a crime is a crime.Only those with the morals of a ferret, fail to distinguish amongst them.Intellect is not the measure of a man.Brilliant criminals, are still sub-human.“There’s no such thing as right or wrong, only fun and boring…” is something expected from a 4 year old. By the age of 5, a rudimentary grasp of the concept of ‘fairness’ takes hold.By 6, The ‘Golden Rule’ is usually not only understood, but demonstrated.Is is possible to be both bright, and morally retarded.

I believe so – it is my honest belief that with such a minimal loss potential (99.99% of the users wouldn’t be qualified to do the hack, unless given a kit), he wouldn’t get any kind of response from the manufacturer. My guess is, that the engineers designing the system had raised the option of using real cryptography, and it didn’t stand a simple accounting calculation of lost profits due to thieves learning of such hacks, versus the expense of using real smart cards, debugging a more complex software, etc.Hence, it’s more a learning opportunity for everyone. Perhaps if enough thieves learn about it from hackaday, the value calculation would look different. I don’t think so – even if such circumvention devices were available as kits (selling of which would likely be illegal) – the company would’ve lost so little of profits it wouldn’t be worth field-upgrading the devices.So everybody, please chill, please stop calling honest people ‘thieves’ (that’s actually slander), and enjoy the technical merits of this post.",

This
elegant looking lamp
uses capacitance sensing to turn on and off. [Mikey77] takes us through the process of making the curved circuits and putting it all together. The circuit is built to be modular, so he could use it elsewhere. That’s a pretty good idea for someone who is always tossing projects together. As usual, schematics are available in the instructable. We love this design and would proudly use this at our office desk.

[Steve] shares another project with us, this time a
robotic foot stool
. A Parallax Propeller micro controller, some linear actuators, servos, and a slew of sensors are enclosed in this vinyl covered cube. It has 3 modes, remote control, follow me (seen in the video above), and come to the beacon. This, along with
[Steve]’s other creations
make us think that his ultimate goal is to have a house full of servant bots eager to carry out every task that would pull him from his chair. That seems like a noble goal to us. You can download source code and schematics from his site. Join us after the break to see more pictures and videos of Robostool.
[youtube=http://www.youtube.com/watch?v=lPnwycXY6lk]
Here you can see the mode where Robostool comes to him. We’re curious how it knew which way to go.
Here is a picture of the internals.

OLED Hack Saves Juice On Nexus One

Want to really stretch the battery life on your phone? If you have an OLED display [Jeff Sharkey] may have the answer. He did some testing with his Nexus One to
see if color alterations can save on current
. Darker colors draw less amperage and he found that the red pixels are the most efficient. He did a little work with
SurfaceFlinger
, which handles the display on Android devices to make this easy, but what will you get by going red? He measured that using only the red pixels dropped the current use down to 35% of what the full color display was pulling. This reminds us of those efforts to
save energy by running a black background with Google
. Whether you use it or not his post is an interesting read.

No hack will be more readily accepted by the significant other more than an automated vegetable watering system. [Jouni’s]
homemade rig keeps those tomatoes happy
with just the right amount of moisture. A bucket serves as the reservoir, a submersible pump gets the water to the soil through a bit of plastic hose. An Arduino monitors the soil sensor, watering and
tweeting about it
when things dry out too much. Don’t miss
the soil moisture sensor post
if you need some tips on how to get that end of things working. The rest is pretty straightforward.

One kick to the bucket and you don’t only have a minor pond, but also maybe a wasted watering system.I’d take something seal-able…and probably include some filling system for the reservoir.

Using a bucket limits my mistakes to 5 gallons max. The timer is set to turn on at 6:15 AM and off at 6:16 AM. The sump pump has an ordinary garden hose connector on the top, to which I have connected a drip irrigation pressure regulator (drops it down to 25 PSI max.) From the regulator, I connect it with an adapter to a piece of ordinary 1/4″ drip irrigation hose. From there, it goes to manifolds which fan out with very flexible 1/4″ aquarium hose to drip irrigation spray nozzles I affix with clothespins. I just point the nozzles at the plants that need daily water.(The mounted plants are all located inside environmentally controlled glass cases which keep the water from being sprayed all around the house.)I had the bucket, pump, and leftover drip irrigation parts laying around the garage. I had to spend $20 for an electronic timer that has one minute resolution. And now we can head off for a week without trying to find someone to come and babysit the plants once a day.",

Coded Safety For Diy Laser

[youtube=http://www.youtube.com/watch?v=2yVtJia5UWY]
Finally we see a hack that is focuses on
safety when it comes to high-power laser hacks
. A safety switch has been added to the butt of the flashlight body which houses the laser diode. When the safety is flipped on an LED blinks to prompt the user for a security code. If you enter the correct code on a momentary push switch, electrical access to the laser is enabled. There are also a couple of nice features such as continuous on and auto shutoff.
This would be hard to implement if you’re working on
a watertight package
but we like the fact that an unsuspecting house guest won’t go blind if searching for a flashlight during a storm. One last thing, the code entry system is PIC based which reminds us of [Alan Parekh’s]
one-button system
.

[Kenneth Finnegan] is back with another video showing some cool stuff he’s doing to
connect his microcontrollers to the internet
. Usually, we see this done with a prebuilt module like an iobridge. [Kenneth] is using a Microchip ENC28j60 module for the communication and he’s managed to stuff it all onto a tiny
Electroboards
piece. [Kenneth] is starting to become
a regular around here

[Carnivore] tried to break as many (unofficial) records as possible when he modified his Apad/M002 into what he calls
Project Apex
. Record number 1: [Derek] claims this is the first Apad mod, ever. Record number 2: 8500mAh battery, giving the device a 12 hour life which is longer than any other
Android slate
. Record number 3: beautiful factory-looking finish. Okay, so that last one isn’t really a record, but we thought Project Apex deserved it anyway. There are a few other modifications done to the device as well; click the link or catch a video of him showing off the slate after the jump.

[Andrew Jenner] pulled off something amazing with this
Physical Tone Matrix
. He wanted to build a physical version of
a flash applet he had seen
. Two layers make up the main user interface. The top layer is a sheet of acrylic that acts as a touch interface and below there’s an LED matrix. [Andrew’s] touch interface uses wires running throughout the acrylic as contacts which are polled via transistor pairs. As you can see in the video after the break it works well and we like the fact that there’s a tactile component (due to the bumpy wires) you don’t get when working with a touchscreen.
The 16×16 grid of LEDs on the bottom layer correspond to each ‘button’ on the touch matrix hand have some extra functions such as playing
Conway’s Game of Life
. This fantastic build still has a couple of kinks to work out, most notably the interference in the audio circuit, but we’re quite impressed at what he’s achieved quickly. Plus, this is more economical than a monome and larger than some of the
monome clones
we’ve seen.

DIDJ Composite Video Out

"composite",

[Nirvous] managed to get
composite video out working on the DIDJ
. He knew that the CPU had the ability to generate the signal, and that similar devices already had this capability. After studying some DIDJ teardowns he figured out which connection on the processor should provide the appropriate signal. Next was the firmware side of things and after sifting through a lot of code he was pleased to find a flag that looked like it would enable video out. Some cross-compiling, soldering, and a low-pass filter got it to work.
If you’ve been
hacking around on the device
you might try this. The CPU uses a ball grid array so soldering is a bit difficult. We covered
a BGA soldering trick
that might be just the thing so check it out before you retreat into your soldering-fortress of solitude.

Regular Hackaday reader [Osgeld] is at it again with this
USB conversion for an NES controller
. This is a ubiquitous hack that we started seeing
very early on
, sometimes involving
an adapter kit
, and other times
including things like a thumb drive and USB hub
. But this time around is truly a bare-bones version. He’s using an Arduino but it’s really just an AVR ATmega168 running the bootloader. We’d wager this can be done with an ATmega8 just as easily. Grab a couple of diodes (we never seem to have the 3.6v zener diodes around when we need them), a couple caps and resistors, a crystal and you’re in business. The hack wires each button to a pin and implements a keyboard HID that can be mapped for any purpose you desire.

[Matt Meerian] introduced us to his kludge of cardboard, tape, mirrors, and electronics in the form of a clever non lethal
robin trap
. Whenever a pesky robin would enter the box, a sensor is triggered, the solenoid drops a lid, and the bird is contained (and we assume taken far away after that).
Of course the plan backfired; we wont spoil what happened, but you can click the link above to find out.

How To Design Your Gears

"gear",
"laser",
"ponoko"
] |
[Dustyn Roberts] takes us through the process of
designing gears for a specific application
. Using
Inkscape
and
Ponoko.com
[Dustyn] takes us from equation to physical gear. While there is a plugin for Inkscape that allows you to basically drag and drop gears, this writeup will take you through the math to get exactly what you need. Those laser cut wooden gears are pretty cool looking too.

The GLIP project
takes the delight of blinking LEDs and combines it with the ingenuity of modular communications. This takes
the Puzzlemation concept
a few steps further. In that project the modules were programmed through a base station and could be removed and used as a puzzle from there. The GLIP project uses a master block that you can see tethered in the photo. But the blocks communicate with each other via an infrared protocol. This way they can be continuously updated as they are place next to each other. Each module includes an STM32F105 ARM Cortex-M3 processor, quite a punch for the little blocks. Take a look at what they can do after the break.

Just the other day we were thinking “You know what we need more of around here? Harmonographs!” And our requests were answered when [Paul] sent in his
three pendulum harmonograph
. For those unaware, it’s a mechanical device that draws Lissajous curves or “really cool circles” to quote some of our staff.
[Paul]
includes all the plans
necessary to make your own harmonograph and begin drawing today. If you can’t wait, there’s a video of the three pendulum harmonograph etching a masterpiece after the jump.

The
Hack a Day store
has a couple new items. It was brought to our attention that we once held a
T-shirt contest
, and people really wanted access to that design. Well, now you can get it. The design on the shirt will be roughly 13″x10″ and located at the hem under the right arm. Please note that this is not identical to the previously made ones that you may have noticed at
CES
. The design is also available as a large sticker.
We would love to see our stuff in the wild, so please upload your pictures to Flickr and put them in the
Hack a Day pool
.

The Arduino platform should be perfect for throwing together a lightweight webserver because of the availability of quality shields that take care of the hardware for you. As [Ovidiu Predescu] found, there are a few hiccups along the way and he’s put together
a guide that covers
the workarounds. Specifically, using an Ethernet shield and data logging shield at the same time produces a bus conflict which he sidesteps by cutting the CS pin trace on the data logging board and moving it to a different pin. There is also a bug with one of the chips on the Ethernet shield that is fixed using a similar method. So if you’re not just going to
etch your own webserver hardware
maybe this is the next best thing.

I started with µCs about 3 months ago and before that i didn’t have ANY background knowledge about µCs, soldering, PCB-design etc. Of course i have a soldering iron and all the needed stuff (at least i hope i have it). So why should i buy several µCs and loads of other stuff just to get a blinking LED? There’s no sense in starting to solder huge logic circuits (555 and 74xx) together without the proper knowledge. I’m more of a programmer and at first, i need to learn the language used in µCs…then i can start thinking about building circuits out of parts on a breadboard instead of just using the arduino.",

Open Workbench Logic Sniffer
or you can do a bit of fiddling to get it to work with your own designs. The program is based on Eclipse so you should be familiar with how it works and you can get it running easily on multiple platforms. Take a look at
the wiki
for a quick start.

Wasp Sucker Clears The Air

[Matthias Wandel] had something of a wasp problem so
he built this trap to catch the pesky fliers
. These look like
Yellow jackets
and they can build some huge nests (check out
the picture
of a 2-year old dwelling). We’ve experienced a large nest in the walls of an apartment and weren’t as clever at fixing the issue. [Matthias’] solution uses a 1/3 horsepower blower to snatch the wasps out of the air and retain them in the trap above. The trap sits on the blower with some insect netting as a filter, the hose acts as the inlet and is placed at the entrance to their lair. It took nine hours to fill this trap; we wonder where he chose to release them. Enemies of [Mr. Wandel] beware.

And pests that threaten my friends and family will be killed without mercy.That being said, I did trap and relocate a squirrel in my attic. I took him 20 miles away (risking “illegal possession of wildlife”) and released him in a park in the middle of late winter. Away from his stashed food, and abandoned in other squirrel’s turf, I have to wonder if it would have been more humane to just have drowned him quickly in my bathtub and make Brunswick stew from his tasty hindquarters.",

RFID Transplant

"pre",
"rfid"
] |
[Zach Charat] didn’t want to carry around yet another card with him so
he transplanted the RFID guts from his card to his phone
. Soaking the card in nail polish remover for twelve hours got him nowhere, but when he broke out the acetone the card was falling apart in 30 seconds. Above you can see the tiny chip and loop antenna that were left after ditching the plastic. The black bits are electrical tape which he then used to embed this in his Palm Pre’s touchstone charger plate ( which we just
saw this in a hack last week
).
This works, and while you’re waiting for the world to implement the
Leeloo Dallas Multipass
it’s a great solution.

Power Cycling A Problematic Modem

"power cycle",
"relay",
"router",
"serial"
] |
[Gigawatts] struggled against a shoddy Internet connection for quite some time. Changing modems, having the line serviced, and spending far too much time on the phone didn’t do any good. In fact, the only thing that fixed the problem was power cycling the modem once it stopped responding. His solution was to
automate the power cycling process
. He added a cron task to his router which is running DD-WRT, a favorite firmware alternative for
hacked routers
. The script monitored the WAN connection and when it went down it would toggle one of the serial port pins. He whipped up an outlet box with a relay in it and used that serial pin to cut the power going to the modem. A workaround yes, but it was the only thing that brought an end to his frustration.

That’s what I get for drawing the diagram AFTER I completed the circuit and put it to work :P It’s fixed now.@NatureTM: This device was only created after going round and round with Comcast for months and them not having a clue what was wrong. I posted a few more details about my experience with the techs in the blog comments. So yes, this is not an ideal solution to the problem, but at that point, when there were no other options other than switching ISPs, I figured, why not :P Plus it was fun to build!@Failure in: I thought about putting it on the DC side, but I didn’t want to destroy the “rented” modem’s power supply and I also liked the idea of being able to reuse the device to switch on lamps or Christmas lights or whatever else I please :)",

You can use a variety of methods for switching outlets, including SNMP (it does have a network conection).The cable modems (cable router in my case) usually hangs on too many TCP connections. I think mine has a connection table (the equivalent of ip_conntrack in linux) with 256 entries. When it overflows, it totally hangs.I’ve written a small shell script on my home server which verifies the modem status and when it is not responsive, uses SNMP to the MasterSwitch to power-cycle it.",

I parsed the data that came back and logged the power levels to a file. I let it run for a few days then when the Comcast tech came out to fix the line again (for about the 6th time in 2 months, after this had been going on for about 4 months) I let him see the log file and he said “Hey – great program. I can see you have a problem here.” It took him about 15 mins to diagnose a faulty connection at the pole down the street and my connection was as good as ever after that.As ever, find the root source of a problem and it keeps the solution simpler.",

We didn’t know anything about hacked firmware, and there may not have been anything for our basic router.We came up with a solution where we had an XP service ping some major websites and if they were unreachable, it would send a signal on the serial port. The box would be used to reset both the modem and the cheapie router. I built a 555 one shot circuit with some circuitry to boost the signal from the serial line. The PC was upstairs, the modem and router were in the basement so it needed some ‘conditioning’. But I was still pretty new to electronics and I made an error, I didn’t do anything to filter the input. When the equipment was connected to the box, the additional EMI from the current draw of the modem and router were enough along with the relay that the circuit would sometimes retrigger :) My ‘fix’ was to put a couple plates of something ferrous enough to block the EMI to make it work reliable for a few years.",

And cheap routers can have NAT tables with as little as 200 entries.Not only file sharing can quickly fill up the NAT table.

You can then pull it low usually, sometimes high for a second and the modem will reset. This way you don’t need but just 2 wires between the two boxes and do not need a relay or to touch anything involving the power supply.If you wanted to isolate the two boxes you could use a single optoisolator between the two. A logic output is more than strong enough to drive one and there are plenty of them that have enough capacity to handle the currents of a reset line.",

[Rui Gato] needed a powerful yet portable machine for his performances. If it’s on stage shouldn’t it look good too? We loved watching him
construct an acrylic case for his setup
. He’s skilled with a rotary tool and the work he put into the case fan grill alone is impressive. Video after the break.

The latter should already be grounded (internally) via the earth ground on the power connector. Use as short a wire as possible, and as thick a wire. Braided ground strap is probably the best. Hams like to make their own braided ground straps by harvesting the woven shield out of old coax.@isamaMore likely than not, all of the standoff pad areas on the motherboard are already tied together by a ground plane on the board itself, so I’m not exactly sure how what you describe is going to benefit anyone.A conductive enclosure is a Faraday cage. Besides convenient grounding, it reduces RF emissions from the computer, and protects the computer from the effects of external signals. It doesn’t look as cool as a clear plastic case, but for me a computer is a tool, and I prefer tools that work to tools that look cool.Barring that, a metallic mounting plate provides a ground plane. Mount everything on the plate. This is not nearly as effective as the Faraday cage, but provides good grounding. The partial shielding benefit is probably good enough to at least justify the implementation.Barring that, you can strap all the various pieces together, but this provides grounding only, no shielding. Do not “daisy-chain” your items. Grounds should be distributed in a “star” fashion— a single common ground point distributed to all components.",

Seeed Studios has a new version of the Arduino that they’re calling the
Seeeduino Film
. Instead of the traditional fiberglass substrate they’ve used a resin material to produce a
Flexible Printed Circuit
(FPC). In addition to its flexibility their aim with this prototype was to keep it modular. From what we can see each of the four squares is a different component in the Arduino system. The photo above has the USB interface on the nearest node, then the power regulator, the microprocessor, and finally the remaining peripheral connections. This material can easily be cut with a pair of scissors so the programming section can be removed once the firmware is burned to the chip. It will be interesting to see final pricing and package options. We wouldn’t mind having an FPC ATmega168 breakout board around, but specifially this would fit nicely in a watch band if you were
building your own wristwatch
.
[Thanks Juan]

I get mine made at Storm Circuit (a Chinese PCB house), and I’ve had good results, even with very fine pitch designs. Just add an extra ‘flex’ layer in your Eagle cad cam setup and the wizards there will work it out. Minco has a really terrific primer ondesigning flex boards.If you’re worried about strain relief as I’ve mentioned in an earlier comment, you can go flex-rigid, but it’s more expensive than regular boards. In my experience I’ve been able to produce prototypes out of flex that saved me substantial money, and rigidised flex is even easier. Save the fancy stuff for when you really need it!And no, flex boards aren’t as cheap as Sunstone or PCB express or whatever short-run company you prefer by dint of the fab company requiring serious manufacturing gear and overheads, but it’s competitive and relatively affordable. I got a baggy of 200 flex boards (15 mm x 10 mm, at 0.1 mm tracks + spacing) for $250. I consider that a bargain.",

Sidecar Reminiscent Of Conjoined Twins

Finally,
an answer
to the problem of sidecar dorkiness. [François Knorreck] spent
ten years hand crafting a sidecar
with a beautiful design and a luxurious interior for two. The frame is aluminum, the body is mostly carbon fiber, and there are countless details such as automatic chain tension control and steering for the sidecar wheel that make this more than just a pretty paint job.

Researchers at MIT have come up with this slick demo of, what they call,
programmable matter
. This flat sheet covered in tiny foil actuators can be programmed to fold into specific shapes. Shown in the video above is a boat and an airplane. Using the concepts set down by origami through the years, they can divide the sheet into triangles in specific arrangements to make certain shapes possible. This one is fairly simple, but judging by some of the insane origami we’ve seen around, this could get pretty cool.

Cameras Perch On Power Lines, Steal Electricity

"induction",
"quadcopter"
] |
[Tim] let us know about a video outlining some
covert camera devices the Air Force is developing
(dead link, try
the Internet Archive version
). The video takes a lot of time to explain induction to those who’ve never heard of it but we liked to see the bird-like concept animations. They’ve already developed cameras that will clamp on to power lines in order to use induction as a power source. Shown in the video is an eight-rotor quadcopter they’re hoping to use to deliver the camera covertly. But the animations show a winged robot similar to a hawk that has a camera for a head. Having seen some of the
other flying devices in development
this may not actually be that far off.

More importantly, power lines are designed to carry a certain weight load (that of the lines themselves) for a set amount of time (typically measured in decades) and in all sorts of weather, also taking heat expansion into account. Attaching these devices to the power lines throws off these calculations, and would likely mean the power lines themselves will have to be replaced more frequently.",

Even if it would be used state-side, it wouldn’t be illegal – it’s the US government. As long as they have a warrant or a purpose for surveilling somebody, it would be no different than having a guy in a panel van sitting across the street.This has a very practical application in covert intelligence overseas. Think that a drug cartel or terrorist cell is operating out of some dingy warehouse in say Somalia or Colombia? Fly a conveniently disguised camera on to a power line nearby, and nobody would suspect a thing. Just because the “bird” doesn’t move for a few days doesn’t mean that it’ll arouse suspicion. People would never think to look there. A small amount of power loss would occur, but it would go unnoticed unless you had an entire flock sitting there. Besides, once they had a few days worth of footage, the “bird” would just take off.I think this is a great idea because the only way it can be disabled is if the power goes out completely or somebody knows it’s there and removes it. If they remove it, then you have the evidence you need to know that something fishy is going on. I doubt this will be its final form anyways, it’s more of a concept project that will find its way into another form.And to all you conspiracy nuts, there’s no need to be afraid of covert surveillance unless you’re doing something illegal. I know Big Brother is probably watching a lot of the moves I make, but I have nothing to fear because I’m not doing anything illegal.

Worth remembering for one reason: if you check it with a multimeter on an AC setting, it’ll show up as zero. Neon testers (or the old Square D probe meters) will keep you alive longer in NYC, and it gets drilled into young electricians’ heads early and often.",

scooter computer
started off as a way to use a couple of LEDs to show the battery charge on his hog. It was based on a Arduino and used a voltage divider to judge how much juice was left. But then he ran across a touch-screen OLED shield for the Arduino and the project started to take off. Now he’s got battery, temperature, real-time clock, and GPS running through the slick-looking display. It may not be a full-blown motorcycle but it gives the
computer interfaces
we’ve seen
for other bikes a run for their money.

Probably more a matter of the huge readout rather than its location on the display, but I have no problem seeing my MPH at a glance. Many of the commercial displays use the same layout, but with an RPM gauge across the top. Who knows, after I get more time on it, I may rearrange the display entirely. Great ideas!

Sure, it has restrictions and it hides lots of things that are really important to know, but (1) experts sometimes want a super-quick way to test some little snippet of code, just type it in and click a button to download it, and (2) it is something that beginners can use to get into microcontroller programming. At some point everyone should realize the restrictions that Arduino puts on the code compared to straight C/C++/assmembly on the AVR (i.e., I/O using digitalWrite() and friends is much slower than raw AVR I/O, it isn’t designed to support low-power sleep, event-driven programming, etc., and it makes other assumptions as well), but many can be mitigated by simply avoiding the Arduino language constructs and using the avr-gcc/avr-libc equivalents).",

This requires pretty specialized tricks on the ATmega328 especially if you want to use the UART (you’ll need to keep the RC osc. calibrated at runtime).My point is, what’s the big deal if someone doesn’t design and etch their own PCB for the AVR for every project? The Arduino, especially variants such as the Arduino Pro mini (but why a ceramic resonator and not a crystal? Crystal please for a few pennies more!) are perfectly suitable for use in many embedded hobby applications.",

Vibration will eat anything in a socket. Use heavy connectors to the bike, not .1 spacing dip headers and ribbon cable. Every connection has to be mechanically strong and compressed.3) Once you have the bugs worked out, conformal coating on the board. Wanna test it for real? Put the whole thing in a paint can supported by foam and duct tape, then go to a hardware store and get it shaken for 15 minutes in a paint mixer.Man, nothing finds weakness like an industrial vibrator. At Boeing [cancelled UFO project], we had big damn oven/freezers that we’d put things in (like paint shakers or vibration tables) and then hit them with salt spray or humidity and run them all over -40 to +80c for a few weeks.I’ll admit, this is overkill, but it compresses a whole lot of failure modes into a few days.

[Derek Diedricksen] builds
nomadic houses from left over building materials
. Some are large enough to haul behind a vehicle or, in the case of the one above, small enough to tote around like a wheelbarrow. We love them because not only do they reuse material that might commonly hit the landfill, but they look good. Check out the first couple of episodes from the Yellow House series after the break. Then take some inspiration from [Derek’s] success and see if you don’t already have enough in your junk pile to get started.

I’ve built a few other structures on the same idea, all in other “Tiny Yellow House” videos…and I have an episode on the way covering my VT cabin- 250 square feet or so.Anyway, real cool site here- and thanks to whoever for posting my link/video here- much appreciated!-Derek “Deek” Diedricksenhttp://www.relaxshacks.com",
