Remember [Mattythorne]? He took a BMW industrial arm and
re-purposed it to write twitter messages
on a white board. You can read a
small excerpt here.
Well [Matt] is back, and as promised includes an entire write up for how he got
@scribblebot
scribbling twitter messages. It’s a little light on details and we wish there was some more in-depth how-to magic, but then we remembered with most of the population not having an industrial arm in the first place the extra time spent incorporating the extra info would be far from worth it. Regardless, it doesn’t surprise that the previous commentators were not far off the mark in how difficult programing one of these machines would be. While such arms do have a few built in libraries it looks like a very exhausting process to override the default axis of motion, incorporate a UI, build a pen holder, and more. And in the end, is it worth it? [Matt] tells us the arm is going to be going back to monotonous car building work soon, giving weeks of prep only a day in the limelight.

Where industrial robot programming gets interesting is when you have to preform a not so repetitive task. IE grinding parts to a close tolerance that are cast but vary +/- 1″ from target anywhere on path, bin picking from random orientations, doing a multi step process where certain steps can be completed in groups but the parts arrive in random time intervals then having to determine how to most efficiently assemble the sub groups and the final part. I am impressed (as always) to see the posters take the topic further and more advanced such as Ashwin mentioning OpenRAVE and kinematic models. Just wanted to give some perspective for those on both camps who say robot programming is easy and those who say its hard you both are correct. For those who say it is easy let me know when you have figured out how to offset a path of 13K point cloud each with a different offset value for griding a part to a 10thou tolerance :).",

[Graham Auld] got his hands on an energy monitor for free from his utility company. The device seen in the insert provides a nice LCD display but he wanted a way to graph the data over time. There was an included cable and a method of using Google PowerMeter but only for Windows computers. He did a little poking around and came up with
a Perl script to interface the meter with Google’s tools
.
The hardware module is known as the
Current Cost CC128
and the developer was nice enough to publish an XML output description which [Graham] used in his script. From there it’s just a matter of registering and authenticating through the
Google PowerMeter API
. The script is not fully polished yet but it serves as a road map for your own implementation.

You might even be using a chain of proxies, or several computers, but that won’t really help you, either. All you can do is pretend that it does… but it doesn’t.Ask the EFF – it’s trivial to identify you. Even they agree that it’s almost hopeless, apart from legislation… yet even the legislation they want will have more loopholes than the fair credit practice act.Google (and other firms) keep dossiers, and has done so for a long time. Why? Because it’s trivial to follow you around the internet – even if you switch from dsl to cable and back again.The bad news is that even your most well thought out anonymity schemes are trivial to figure out – and subvert. Having comprehensive maps of individual behavior is valuable to many firms and organizations, who will gladly pay for it.It’s trivial. It’s even more trivial to associate all your email accounts – no matter how anonymous you think they are, and tie it to your real address and name – and thence to your credit history… and cellphone data. Think this is a paranoid rant? It isn’t – check your state’s privacy laws and notice that call info is not considered private, and can be sold or traded.Your cellphone data pretty much allows companies (or people in the companies) to map where you spend your days and nights, and makes it trivial to accumulate pictures of your daily activities… not to mention archives of any photos snapped by your camera. And now that it’s trivial to record, compress and store speech, every conversation you have is recorded… for what are euphemistically called “voice quality maintenance purposes”.Isn’t that cool.BTW, the image capture function in modern cellphones can be triggered remotely… as can the microphone. That applies to most laptops as well, and apple just created a small tempest by patenting the ipad’s ability to identify you… and measure your heartbeat as a side effect.Anyway – the bottom line: Anonymous accounts and throw away cellphones don’t fool anyone but some stranger you tried to hook up with.

No. But your mistake is in assuming that what you write is true:“it’s impossible to sift through all the trillions of bits of data, you have to be targeted, even for commercial purposes they would run a script and do basic stuff to get some demographic numbers and maybe do some targeting of personality types for ads, but it’s just not economically viable to put an analyst on every person on earth”I never said that each individual had a watcher. I simply said that the data exists, can be correlated and stored, and that this is being done on a growing scale.– impossible to sift? Au contraire. Drawing conclusions is hard, but sifting is very easy.– trillions of bits of data? Not even. An average cellphone user log containing call lists and cell location data for a week is <16k of data plus some account overhead. How big must a database be to profile the whereabouts of 1 million cellphone users? ~20 GB. I assure you – an off the shelf $600 PC is more than enough to keep tabs on several million people.But you were probably talking about web and email usage. I'll just suggest that if you're using throwaway email accounts, you might take a few moments and peruse the HTML source of the web interface. The web may be stickier than you think… and the proxy thing is designed to foil MITM attacks, but it assumes that there is no way to correlate between ingress and egress.I have no doubt that a well-disciplined and well-connected uber hacker following strict protocols could maintain multiple identities on the web. But I also think that joe \"I know who schneir is\" public and jane soccer mom ought to know that it's trivial [ :) ] to link their personal porn, private interests and political habits with their public persona… and that of their friends.Again, my complaint isn't that it's being done – it's just that I want to subscribe to my own panopticon data.

This beautifully crafted
Daft Punk table with iPod dock
was built by [Dustin Evans]. The table itself was built with the help of a friend in one day with electronics added a bit later. It features an 8×8 grid of boxes with red LEDs mounted inside. The picture above is not quite the finished product, a diffuser will be added later to augment the scattering of light already provided by cutting the tip off of each LED. On the underside you’ll find a power supply and a set of speakers. The system is controlled by an Arduino which resides in the same drawer as the dock. See the final product in the clip after the break.

Intel: High-bandwidth Digital Content Protection Cracked

Intel says that
HDCP has been cracked
, but they also say that it’s unlikely this information will be used to unlock the copying of anything. Their reasoning for the second statement is that for someone to make this work they would need to produce a computer chip, not something that is worth the effort.
We question that logic. Not so much for Blu-Ray, which is the commonly associated media format that uses HDCP, but for HD digital cable programming. There are folks out there who would like to have the option of recording their HD television shows without renting a DVR from the cable company.
CableCard tuners
have been mostly absent from the market, making this type of recording difficult or impossible. Now that there’s a proven way to get the encryption key for HDCP how hard would it really be to create a man-in-the-middle device that uses that key to authenticate, decrypt, and funnel the audio and video to another encoder card? We know next-to-nothing about the protocol but why couldn’t any powerful processor, like an ARM, or even an FPGA (both rather inexpensive and readily available) be programmed for this task?
Leave a comment to let us know what you think about
HDCP
, and what the availability of the master-key really means.
[Thanks Dave]

I hope people aren’t scared of intel and go ahead and destroy HDCP once and for all; it’s done little to nothing to prevent copyright circumvention but it’s been a huge pain in the ass for tons of customers that just want to use the shit they paid for (I work in a TV shop; we get just about every complaint possible, so my perspectives a bit different).",

HDCP is just a handshake, the “decoding” process is simple, the content is not encrypted bit by bit. The simplest way to put it is that the displat device tells the playback device “I’m cool man” and playback begins, the handshake continues ad infinitum down the data line until playback ends, the dongles just spoof it and pass the rest of the signal on to the non hdcp device.",

No you cannot just copy that file and read the key as the file itself is encrypted. It would be a headache for consumers but no reason why manufacturers cannot implement another key.All this will do is lead to more intrusive DRM, people seem to think that if they crack enough hardware the manufacturers will give up, sorry not going to happen, you only make them more determined.

USB Host Comes To Zipit

"zipit"
] |
This USB to Zipit Dock adapter and a special kernel makes
USB host mode for the Zipit possible
. Previously, the cheap and hackable wireless client needed a hardware modification to enable USB support. The new kernel bootloader, called
U-Boot
, makes the internal alterations unnecessary (see the demo after the break). Now the only caveat is one of voltage. Zipit only supplies 3.3V when running on battery so your choices are to only use USB when the Zipit is plugged into a charger, or use a powered USB hub. But if you’re already building a hub adapter it shouldn’t be too much trouble to add in the option for a battery-powered hub.
So can we
play our NES games
using
a USB controller
now?

And we need to share reports about our projects using their code..That’s said also to remind us about how important feeding back our user reports can be. The developers of software that unlocks devices cannot try their code with all of the USB stuff in the world. So- our reporting pass/fail reports about USB stuff to developers that ask us to- is a Very Good Thing. Both for the developers and everyone else.Moving on to my idea for using the unlocked Zipit.I have a 2gb music player/FM transmitter that’s built into a case style like a phone’s car charger. Micro Center often sells open box returns of similar units for<$20. It has a USB port for song loading/playing music from Flash Drives. If it would be interoperable= controllable- with the USB Host modded Zipit? Then it might be used to have a FM transmit output from the Zipit. I do accept that some of the details will be non-trivial. But if it were trivial, it might not be worth space here.There's a few \"interesting\" social hacking applications for a compact WiFi remote controllable FM transmitter.",

One MAJOR problem I have with the DC-DC converter is that if I hotplug the dongle into the back of the Zipit, the whole device dies. I’m assuming this is from a voltage drop but I’m not sure. Even without the hot plugging though, I’ve still not been able to make it work for some reason. I DID however find a DC-DC converter with nearly perfect specs that is small enough to fit into the expansion connector housing. And I disagree about murdering the battery life. If you are just using some low power device such as a USB memory key, the dc-dc converter won’t be drawing very much current. Remember that’s one of the benefits of switch mode power supplies. Here is a picture of what my adapter looks likehttp://www.notanon.com/usb_dongle.jpg",

I’ve not tried measuring the amperage between the boost converter and the Zipit yet but I think that would be a good next step to see what it’s actually pulling. I certainly wouldn’t try to power a hard drive or even a hub off of that dc-dc converter but a small memory device or even a mouse SHOULD work. The device as shown in the picture DOES seem to work as far as power is concerned. I think my problem with devices not recognizing stems from a grounding issue or something more along those lines. The expansion port was originally designed with an add on camera peripheral in mind although I’m sure that design worked on the 3.3v.",

Line Following Tank Without A Microcontroller

This
line following tank
uses analog circuitry to sense where a dark line is and adjust its course. Despite the opening paragraph on
the schematic page
(which looks to be leftover from a past project writeup) this circuit relies on a set of transistors for motor control. [Chris] does a great job of explaining the setup in detail; it boils down to a phototransistor detecting reflected light and flipping which motor is running based on what is detected. A couple of potentiometers are included to tune up the accuracy of the circuit. There’s a short clip of the treaded-terror making a loop around the track after the break.
This is another great way to
try your hand at analog circuitry
. Once you’ve built the body (tank or otherwise) and line tracking circuit it can be repurposed by swapping out the brains for your next project.

3D Digital Light Art Using IPad And Camera Trickery

This
light art is created by a moving display
playing an animated image through several camera exposures. In this case the display they’re using is an iPad, but that really doesn’t matter as it’s just a high-quality screen and it’s portable. 3D animations are generated in software and then sliced into cross sections. As the camera rolls, the cross sections are displayed in order and the location of the screen is moved. Very much like
light painting with an LED
or
a Roomba
, the bright image remains and can be strung together for the 3D effect seen in the video after the break.
Using the cross sections of the video reminds us of what a three-dimensional object looks like to a two-dimensional being. If you have no idea what that means you should take a look at this
video on imagining the tenth dimension
.

Want to try your hand at building a Linux package for an embedded device? [SnowBot] decided to give it a try and set out to
build Ubuntu for a GumStix
. The single-board computer will cost you about $150 to get started, plus a way to connect to the device’s serial port. But once you’ve got your hands on it there is a lot of power in a tiny package.
He’s using
the RootStock package
to assist in the build. This is a suite of tools that generates the root file system that can be loaded onto an SD card for use with the Gumstix. It’s not quite building from the ground up, but there’s already enough hoops to jump through that this package is a welcomed shortcut.
Already rolling your own Linux packages for embedded hardware?
We want to hear about it

That’s right, Benjamin J. Heckendorn (aka Ben Heck) has started churning out episodes of his own Internet TV show. We finally got around to
watching the first episode
and enjoyed it greatly. You’ll see him alter an Xbox 360 controller for a disabled gamer, making custom foot interfaces to take over the traditional role of your right hand. Also in the episode is part of a big build; making an Xbox 360 laptop out of the new slim model. We’re very interested in that overall build, but in this episode you only see him removing the components from the factory case. But we guess the promise of seeing the rest of the project is the hook to get you to watch the next episode.
Think that you haven’t heard of Ben Heck before? If you’ve been following
Hackaday
for a while you have. We’ve looked in on quite a few of his builds over the years, including his
pinball machine
,
Xbox 360 portable
, and his
access controller
.

[Ladyada] takes some time out of her day to explain
the common options available for connecting projects through USB
. You may be thinking that you already do this with an Arduino. Well, yes and no. The Arduino uses one of these options, an FTDI chip that handles the USB on one side and spits out microcontroller-friendly voltage signals on the other. This chip can be used with your projects, a topic that [Phil Burgess]
covered in great detail
.
In the video after the break you’ll also hear about USB to serial converters which connect to the Universal Serial Bus and output the traditional 12-20V serial signals (with the exception of
cheap knockoff cables like the one from last week
). These need to be stepped down to 5 volts or less using a MAX232 chip to work with your project.
Finally there’s the option of using a microcontroller running the
V-USB firmware package
. This is how the
USBtinyISP
works and I’ve used it in my own projects
to build a LIRC compatible IR receiver
.

Now with a little hacking, via a little USB hub you can connect your phone and your USB drive together. Make the USB drive look like a mass storage device to the phone. (I’m not exactly sure how to do that last bit though or if it is even possible.)The router can also act as network attached storage and/or run a torrent client in the background (wheeeee this is fun!)The ASUS WL-5200GU WiFi router can be found super cheap sometimes (around $25 USD) and it has a USB port. But there is some debate as to whether the USB port is 2.0 or not. The ASUS WL-5200GU has a firmware upload button on it that makes it almost impossible to brick.Good Luck, David",

This seems like it would negate the benefit of the isolation, other than protection from high-voltage spikes. If you think your project may damage the serial port built into your computer, test it first on an external USB to serial adapter…Also, I should add, in response to the comments above, that the purpose of the higher signaling levels and positive/negative shift is to increase the distance that an RS-232 signal can reliably reach. Of course, this isn’t necessary for local microcontroller programming, but it has it’s place…",

The line between serious research and well-executed hacks has been getting pretty blurry lately. The device above could have been designed in your basement but it actually comes from researchers at the University of Washington. They are
working on low-power home automation sensors
for monitoring things like humidity, temperature, air quality, and light. The key point in their research has been the use of a home’s electrical system for wireless communication. Operating at 27 MHz has proven quite efficient to the point that one of these modules placed within 10-15 feet of an electrical run can communicate with the rest of the home, powered only by a watch battery projected to last ten years.
That’s kind of exciting, it’s a heck of a lot easier to produce and distribute a set of small boards like this than to run communication wiring throughout the house. Now we just need to pair this with
the Air Force’s parasitic power work
and there’ll be no need for a battery at all.

But i can post the schematic / board layout for the sensors and the arduino shield later today.Cost:I try to keep everything cheap. The most expensive part are the RF modules at ~5 EUR, i would love to replace those with something cheaper, but haven’t found any good alternative so far.Rough EstimatesTemperature Sensor:Attiny45 (a Attiny25 would also be enough) – 1.50 EURRF module – 5.00 EURa NTC Resistor, a diode, a few resistors… – 1.50 EUR= 7.00 EUR in totalArduino shield:RF – Module – 5.00 EURIR Parts – 2.00 EUROpto Couplers – 2.00 EURBits and Pieces – 3.00 EUR= 12 EUR in totalArduino + Ethernet shield = 58.00 EURRemote controlled outlets:3 for 9.99 EURIR Universal Remote:9.99 EURRF Radiator knob:25.00 EURJust some rough overview, my aim is to have the base module with a few temperature nodes and a couple of outlets below 100 EUR.In the future i want to transition from the Arduino to a bare atmega 644 and then probably to an beagle board. this way i could have the server run on the controller directly.If i ever become satisfied with the current state, i will definetly make a writeup / explanation page and submit it to hackaday and post it on the arduino forums.",

Since a wireless sensor usually spend 99% of its time sleeping, i imagine that it would be possible to encrypt the traffic for anything but extremly low power devices.I believe the bigger danger lies in the webfrontends.

Helpful hint number one: “Subscribing” is not the same thing as “reading.” If you had actually read QST over a “life-long” interval, you might have learned something.On the contrary, it is apparent that you know nothing about frequency allocations, RF propagation, transmission lines or antennas, and more importantly, you know absolutely zilch about information theory.Ok, suppose you’ve waved your magic fairy wand and all hams have disappeared.

How many in the 300 khz wide 40 meter band?All of the HF ham spectrum space *combined* is less than the bandwidth of a *single* channel of analog video. Sorry, that’s not “most” of the spectrum. It’s not even a tiny sliver of the spectrum. But then, don’t let me burden you with facts.Seriously, dude, if you have some obsessive hatred for hams, that’s your business… more power to ya. Your arguments, on the other hand, display a fundamental ignorance of the subject.",

In fact, digital signals use more bandwidth than their analog counterparts. Without getting into too many specifics, allow me to provide an idea for consideration:The bandwidth of a function is related to it’s size in the frequency domain, that is, taking the Fourier Transform of a function, and looking at the graph will allow us to see it’s spectral components (it’s power at a certain frequency). Let us consider the most basic of digital transmission, switching something from off to on, then back off again. A square pulse. A square pulse actually consumes infinite bandwidth! The square pulse’s Fourier Transform pair is the sinc function, which never ends.In real life, better pulse shapes are chosen, but the same principle holds true, you cannot manage to cram more information per bandwidth using a digital transmission. I don’t mean to incite a lecture on how my situation is unrealistic (it is, but the math is a bigger pain otherwise), but instead illustrate that osgeld does not know what he is talking about, or have any insight on how a communication system actually works.Regards.",

[Doug] needed to update his watering system to comply with his city’s new water saving ordinance. The old system wasn’t capable of being programmed to water only on even or odd calendar days. Rather than purchase a replacement
he decided to build his own sprinkler controller
. It needed to switch 12V solenoids, a job that’s not too hard to design for. Rather than re-invent the wheel, he modified a previous controller design. It is basically an Arduino and Ethernet shield on a his own etched board. In addition to the ATmega328 and an ENC28J60 (for ethernet connectivity) there is a bank of transistors to drive the watering solenoids. Now he has a web interface that controls the watering schedule and is fully in compliance with the new city code.
If you need another way to save when watering your grass you should take a look at the
sidewalk-avoiding sprinkler

Then I can click a valve on and off quickly as I am doing maintenance.On another note, I am frustrated by the lack of flexibility that comes by fixed zones defined when irrigation systems are installed. This sprinkler system was installed by the previous owner of the home, and it has some design problems such as rotor and spray-type sprinklers on the same zone, and a zone spread across shaded and sunny areas.If I ever install a new sprinkler system, I am definitely going to put an individually-controllable valve on each sprinkler and design a custom controller so I can optimize each sprinkler. Then I am not locked into the initial system design and it’s also easier to expand the system because all water lines can be connected, and control data to all sprinklers can come over a shared data line (RS-485, etc.).",

Wii Sensor Bar Projector

Having experienced quite a bit of trouble getting the Nintendo Wii remotes to work reliably with his home theater projector, [Sprite_TM]
designed his own sensor bar replacement
. If you’re not familiar, the Wii remotes have an infrared camera in the tip that sense two IR LEDs in the sensor bar that resides above or below your television. The problem is that if you’re too far away, the points of light are not where the remote expects them to be and the cursor will not perform as expected. Since this is a huge projected display it’s no surprise that the player is further away from the screen than the system was designed for.
[Sprite_TM’s] solution was to build a projection system for the two IR points. The unit in the picture above is a driver circuit with two IR emitters mounted on a heat sink, each with its own reflector. The reflected beams are shined through a Fresnel lens and projected on the same wall as the TV image. The viewer will not be able to see this light as it’s in a longer wavelength than the visible spectrum. But the Wii remote performs beautifully now and the replacement sensor bar is happily mounted out of sight above the projector.

Dead Motor? Think Again

While hobby brush motors are pretty cheap now adays, there’s always that feeling of why replace when you can rebuild and reuse. As such [John Carr] presents how to
change the brush position in motors
to revive a dead motor. So long as the motor dies from
natural causes
commutator wear
, the idea is the brushes can be moved along the axes and fixed to a new portion of commutator that’s not worn at all. [John] also goes through the details of some tricky reassembly, but we think to make this complete a guide on brush replacement and commutator replacement might be in order

[Shay] and his friend built some battling robots for a school project. Instead of destroying each other’s robots with saws or torches,
they are playing laser tag
. Each robot sports an eeePC, a laser pointer on a movable arm, and some photoresistors. The goal is to get your laser to hit the other robot’s photoresistor to lower its health towards a kill. A server keeps track of the bout, monitoring shot fired because you won’t find unlimited ammo in this game. As for piloting the rig, the netbook webcam is streamed to a control station with an Xbox 360 controller for motion, aiming, and firing. Check it out after the break.

This
laser message scroller
is built with inexpensive parts. The heart of [Raul’s] system is a spinning pill-box with eight mirrors on it. Each redirects the laser to a different vertical portion of the projection surface. There are eight small arms on the apparatus that each break the beam of an optical sensors as it spins, facilitating the precise synchronization needed to generate the projected image correctly. In the video after the break we can make out what looks like an Arduino controlling the system. This makes sense as it’s easy to connect the laser pointer and sensor, and the USB connection allows for the streaming of messages to the system.
Want to see a more complicated setup? Check out the
POV laser projector from a few years back

Raul solved this elegantly by adding more “fins” – each fin triggers the interrupt routine once more. so the CPU has more times to correct itself according to the real world. with my setup, i was able to get about 213 pixels per full mirror rotation, which translates to 26*8 resolution :(actually, since the arduino has 2 interrupts available, it’s possible to use one for “full rotation” and one for “new mirror” and do away with software sorcery… thanks for the inspiration!",

Behold [Retromaster’s] field programmable gate array
implementation of an Atari 2600
. The processor and video chip have both been built in the 100,000 gate Spartan-3E FPGA, with connectors for audio, video, and a Sega controller. The output signals are generated using two DACs made from R-2R resistor ladders, much like
the project we saw in August
. [Retromaster] included functionality for the system switches (difficulty and select) in the controller itself. There is VHDL code and board details available if you want to make one of your own. To help in making that decision we’ve embedded video of it after the break.

But we made a regular NES – not a SNES (and, in the interest of being exorbitantly pedantic: it was in EE324 with a regular Spartan-3, not EE214 with a 3E).Now, if someone *has* actually gone and implemented a SNES in an FPGA, then I would be truly impressed! We briefly considered it after getting our NES working, but @nes is quite right in asserting that it would be a huge undertaking. Not impossible, mind you, but vastly more difficult than a regular NES – owing partly to just the increased complexity, but more-so owing to a lack of good documentation about the very low-level details of the SNES chips (rather than having a nice cycle-accurate description of each chip’s internal behavior to implement from, you have to actually do some real serious design work to correctly implement all of the externally-visible behavior). I’m sure you could fit it in a moderately sized FPGA, however – the SNES isn’t *that* much more complex than a regular NES.And, @Retromaster: awesome work! Fitting all of that in a 100K gate FPGA is certainly a feat, and major kudos for writing the 6502 from scratch – that’s something I’ve been wanting to do for quite some time (for now, I’m relying on a core from OpenCores).",

PSGroove On A PIC Microcontroller

There’s now
a method of using PIC microcontrollers to exploit the PlayStation 3
. This is centered around a PIC 18F2550 which has been
popular in past hacks
because of its built-in USB serial port. This again makes use of
the PSGroove open source exploit code
and, like
the TI calculator version
, seeks to expand the selection of hardware the code runs on.
In addition to the chip and a PIC programmer you’ll need the CCS compiler as others cannot successfully compile this code. A licensed copy is necessary because the demo version of the CCS compiler doesn’t support this particular chip. Add to that the fact that because of the timing it may take several tries to achieve the exploit and you may find yourself disappointed by this development. But there’s always room for improvement and this is a proven first step on the new architecture.

The Insignia Infocast is a $169 simple media device being sold at Best Buy. Marketed as a way to share photos and run Chumby apps,
hackers are starting to release packages to extend its features
. [Bunnie] shows us one package in particular that allows it to be used as a web browser with an external keyboard. With an 800Mhz processor, an 800×600 touch screen, and 2 GB of memory, we can see that this is just scratching the surface of what is possible. [Bunnie] points out that some people are working on porting Android to the device, and if you really feel adventurous, you can
dig into the hardware
.

Quadbike: Bigger Is Better

"big dog",
"bike",
"burning man",
"cycle",
"lawn chair",
"quad"
] |
[Tom Wilson] has finished his latest human powered quadcycle.
The BigDog
, as its called, seats 4 persons in lawn chairs who pedal to their destination. We say latest, for [Tom] also made a slightly smaller version called
The DogSled
. Some improvements include being taller (8 feet total), larger (11 feet by 6 feet), and surprisingly lighter (over half the weight, bringing it in to 450 pounds). The build process is just as impressive as the bike itself; using pneumatic disk brakes to golf cart axles to even drainage pipe, its a perfect fit for
burning man
. Catch a video after the divide.
[Thanks Mowcius]

Ritewing Zephyr Build And Flight Footage

That’s a camera perched atop this aircraft’s wing. [Trappy]
built the video system into his Ritewing Zephyr
and his test flights in the Austrian Alps make for some breathtaking video. The foam wing is pretty easy to work with and the tool of choice here is a hot knife to cut out cavities for the electronics. The total build time came in between ten and twelve hours, but this isn’t the first time [Trappy] has worked with this model. We’re not sure what setup he’s using for control, we’d guess
something head-mounted
, but do take a look from the cockpit after the break. You’ll like what you see.
[Trappy] informed Hackaday that he’s planning some altitude and distance testing next weekend. The goal is to reach 15,000 feet and a range of 12 miles.

"content": "Hi guys,first of all thanks mike for that excellent write-up!and thanks for the praise. glad you enjoyed the video. I feel like I should clear a few things up. there are 2 cameras on board. one is “SD” and transmits down to the pilot who controls the plane through video goggles. the other is a “GoPro HD” helmet camera which records HD footage – and that’s the footage we used to make the video.the R/C is an add-on module that transmits over walkie-talkie band and gives incredible range (50-60 miles easily doable) and reliablity (digital frequency hopping link).we didn’t stabilize the picture or the plane because that would indeed make it harder to “read the air”. also there is no aim to make any kind of professional video with it, it’s purely about fun and adrenaline.there are indeed night cameras (I have a few waiting to be tested here). they aren’t IR but they amplify the light that’s available giving enough picture to fly by night.you can see one of my first planes here – the link is about 2 years old. it goes a bit into the ground aspect as well, which I didn’t cover at all in the build-log of the video.http://www.youtube.com/watch?v=CajNT7BBdFAI’d like to try some 3D at some point, but I’m just a university student at the moment and can’t afford 2 of these cameras. I’ve contacted GoPro already for sponsorship but haven’t heard back, so I guess they weren’t that interested :)Cheers,trappy",

Here’s
a Blade Runner umbrella build
that is done just a little bit too right. It delivers a double-dose of geekery with its lightsaber-gone-rain-protector look but where we think it crosses the line is at the built-in audio system. When you turn it on it plays recordings of popular lines from
Blade Runner
, something that might not fly in public. But the quality is in a different galaxy compared to the
dollar store illuminated umbrella
that we looked at last year.
[Erv’ Plecter] replaced the central support rod for the umbrella with a clear polycarbonate tube. An optic cable snakes through the hollow tube, illuminated by a Luxeon LED in the handle. The custom PCB and 900 mAh battery are both housed there as well. Take a look at (and listen to) the demo after the break. We’ll need to add this to our future projects list right after that
Lightsaber movie replica build

Automated Entry For A Garden Gate

"electronic strike",

[Dan McGrath] tipped us off about a solution for a problem that most people don’t have. He built
a web-based entry system for his garden gate
. This isn’t quite as original as
that chain and sprocket dorm room system
, but it does use a keypad for entry. [Dan’s] already got a web server and home automation box that is always running. He coded a webpage that presents a virtual keypad for code entry. If the right code is input the system unlocks the electronic strike on the other side of this gate. Since the interface is a web page you can load if from any web browser (an iPhone is used for demonstration purposes after the break). But if you don’t have internet access you’re in trouble; there’s no physical keypad. But we guess you could always just jump the fence.

Robotic Eye Surgery Controlled With Magnets

If you’re in need of eye surgery you might just find yourself strapped into this contraption. It’s a
magnetic field generator used to manipulate a tiny, untethered probe
. It’s called OctoMag and the idea is that a robot less than half a millimeter in size is injected into your vascular system and, through the use of those coils, it busts up blood clots in the small passages inside of the eye.
Once you’ve seen the clip after the break we’re sure you’ll agree that this is amazing technology. Nonetheless it makes us cringe to think of the procedure done on a living organism but we’re sure that fear will subside given time. For now this seems more like a treatment from
A Clockwork Orange

Because the Arduino is in such high demand for producing
multiple musical tones at the same time
; [Jeremy Blum] has successfully figured out the math and other necessaries that will take your once previously single tone producing MCU and turn it into a 5 tone producing machine. unsurprisingly its really just some creative use of PWM control but it all works out in the end anyway and helps prevent you from purchasing additional
sound generating chips
. This truly does open up some new doors, as [Jeremy] shows with his still in production
thingamakit
like project:
ReacXion

[Deadbird] decided to use a LEGO 8880 Super Car as a host for all of his electronic tinkering.
Throughout his blog
(
translated
) you’ll find the vehicle with an Arduino MEGA interfacing various prototyping bits. It starts with the motors for locomotion, closely followed by a servo for steering. From there we see the addition of a breadboard and graphic LCD screen. So far he’s worked out the use of a PS2 keyboard as a controller and, most recently he’s
interfaced a Wii Nunchuck
.
We’re more used to seeing
NXT kits adapted for wider use
, but if you’ve got a nice kit like this one it makes a great base onto which you can add your own robotic elements.

[StaticChanger]
built a scoreboard
to display his kill statistics from Halo for the PC. Yes,
we’ve seen kill counters before
, but we like the way that he gathers the data. This project is
reading the score directly from an address in memory
.
Using a program called
Cheat Engine
, the memory used by a program can be sniffed. After a few passes, the program will help you find a static memory address for your desired data. Once you have that it’s just a matter of using a pointer to that address in your desired programming language. In this case, a C# program polls the value and instructs an Arduino to display the value on a couple of 7-segment displays. Voila, the number appears next to your screen as you see in the image above.

Halo is a console port. Would that mean its memory locations are, by nature, more static?2. Also regarding cheating, would some anti-cheat measures notice you’re running a program that checks specific addresses? I don’t really know how deeply the anti-cheat software checks for things like this.3. What happens when you’re not playing Halo? Random segments lit as random data passes through that memory location?",

I wrote my own while I was in college.2)Dynamic memory locations are easy to account for. There is usually a pointer at a specific offset that is itself static, which holds the address of the value you are trying to find. Instead of reading straight from a dynamic address, you read an address from the pointer, then read the value of that address.3)When reading memory, you ALWAYS ALWAYS ALWAYS use window handle or process address. If your stats are not available you have a few choices. You can set NULL values, you can freeze the last known values, or you can set an error state.@Ploogle,I do not think that game dev’s will implement something like this for security reasons.",

Though I don’t use Cheat Engine or C#.Basically, Cheat Engine is an easier method than using a debugger and figuring out what is actually happening in the code. What the application is doing is dumping the process from RAM to a file so you can search for a value, then repeating and seeing which values change to get a specific address. Once you have a dynamic address, you find the static pointer and do something like:ReadProcessMemory(ReadProcessMemory(Pointer));Where the first RPM is to get the dynamic address (byte) and the second is to get the actual values. Normally you just need one of the values (for instance kills) and then extrapolate where the other values are based on structs used in the code. Kills and deaths are usually one byte apart in my experience.@nimrodI don’t think it’s supposed to be a challenge.

This laser engraver
was built using printer parts, a CD-ROM carriage, and some homebrew electronic boards. The laser diode is a 1-Watt model similar to what we saw used as
a weak laser cutter
back in August. When the width of the material changes the focus of the laser is affected so the diode was mounted on a CD-ROM carriage (in the Z axis) for easy adjustment. The X and Y axes are made using parts from Epson Stylus 800 and Epson Stylus Color II printers. After the break we’ve embedded a video of the machine engraving some wood using
EMC2 software
on an Ubuntu box. It also boasts the ability to cut paper and some plastic but it can’t compare in power to
a CO2-based unit
.

Want to control things with your mind? The Emotiv EPOCH EEG is one of the best pieces of hardware you can get that is ready to be hacked into your project. Too bad the entry-level SDK will set you back $500. Or you can take advantage of [Cody Brocious’] work by using
his Emotiv Python Library
. He sniffed around the data coming in over the USB connection and discovered that it’s encrypted. With a bit of trickery he extracted the key and built the 128-aes decryption routine into his package. So far this just pulls raw data from the unit so it’s up to you to figure out how to properly filter the signals and differentiate which sensor corresponds to each data stream. But it’s a start, and hopefully it’ll lead to more
mind controlled doo-dads

IIRC the price was dropped significantly, but they still wanted too much $$$ for a trivial software plugin. I understand the need for emotiv to make money, especially given how long they delayed it, but it seems they’ve taken it too far. The full realization of this came when I noticed that they wanted to distribute applications for the Epoc through an iTunes-esque app store… which is of course, as a middleman, the easiest way to make money without really doing anything.",

Analog Style LED Clock

We spied
this pretty LED clock
this morning and were impressed with how cleanly it was constructed. It was built to mimic an analog clock, so you have the typical hour markings and a minute and hour hand. The minute hand stays in each position for roughly 2 to 3 minutes. The brains behind all those LEDs are a PIC 16f877 with a DS1307 realtime clock. Over all, [WellyBoot] soldered 169 LEDs into place, and did it in a nice clean fashion. We suspect that if we had done it, it would resemble a spaghetti pile. You can see the schematics and build pictures on his site, or watch a video of it in action after the break.

Home Made T.E.A. Lasers

[Nyle] was interested in building lasers at home but felt that the exotic parts list was just too daunting. That was, until
he discovered T.E.A. lasers
. T.E.A. lasers can be constructed from a few bits of aluminum and some high voltage. They emit UV light, as you can see in his examples where he shoots them through a jar full of water with highlighter ink mixed in.
He has posted several variations of different sizes as well as numerous images of them in action. You can see a video of one in action after the break. We also have to point out the fantastic music in the video. It reminds us of those school videos left over from the 50s.

It would take 1000 of those to equal the power of 1 watt, all else equal.“Swiss doctors reported a case of a boy who bought a 150 mW laser, sold as a “laser pointer,” which left him temporarily blind in one eye, and with 20/50 vision in the other eye, after he shined it in a mirror. The boy’s vision eventually returned to near-normal.”A 1 watt laser is considered a Class 4 Laser.Class 4 lasers include all lasers with beam power greater than class 3B. By definition, a class-4 laser can burn the skin, in addition to potentially devastating and permanent eye damage as a result of direct or diffuse beam viewing. These lasers may ignite combustible materials, and thus may represent a fire risk. Class 4 lasers must be equipped with a key switch and a safety interlock. Most entertainment, industrial, scientific, military, and medical lasers are in this category.You can cut (as in separate) non metallic things with a 20 watt CO2 laser, with considerable speed. That includes meat, plastics, etc.Extra bonus – a UV laser isn’t really “visible” in the sense that a “normal” red laser is. I don’t want to sound reactionary and overly safety oriented but lasers are serious hazards if used incorrectly so proper safeguards and precautions should be taken prior to their use.",

If you have a UV laser that is powerful enough to do any damage, like my big excimer, it ablates the surface and does not penetrate deeply. This is why excimer lasers are used for LASIK eye surgery.@MrXFlourescent dyes will lase with a nitrogen laser. “TEA” is just the excitation method, not the laser itself. These are also known as atmospheric nitrogen lasers. They require little in the way of a resonant cavity and will work without mirrors but they are more efficient with. Even something as simple as microscope slides works well for cavity optics. One other thing is that N2 lasers do like to be ran at slightly below atmospheric pressure.You can also get an old excimer from a lasik machine and run it on nitrogen instead of the nasty excimer mix (Usually Argon or Krypton and Fluorine). They do run at about 3 atmospheres in the chamber.",

A polycarbonate face shield is adequate to keep *stray* UV (at 248nm from a KrF excimer) out of your eyes. If you were to look into the beam directly (which they tell you not to do ANYWAY) with a pair of goggles on, then you probably deserve to be blind.From Wikipedia:http://en.wikipedia.org/wiki/TEA_laser“These first “Pin-Bar” TEA lasers, operating at around one pulse per second, were easy and cheap to construct. By operating at atmospheric pressure, complex vacuum and gas-handling systems could be avoided. They could produce MW peak powers of a few 100 ns duration capable of breaking down air if brought to a focus with a short focal-length lens. Disadvantages were poor gain symmetry, dissipation in the resistors and size.”",

Two projects for the price of one, and a weekend spent coil winding! I first heard about this sort of laser reading about tesla coils; the design there involved a simple chamber around the electrodes with bottled nitrogen gas being blown into one end. This should allow for faster pulse rates and possibly higher powers as oxygen poisons nitrogen lasing.Safety wise, you’re significantly more likely to fry yourself using the HV power supply than you are to blind yourself with the laser. Also, I’m not totally certain that UV lasers will necessarily induce permanent blindness due to all the beam energy being absorbed by the front of the eye; you’ll get some nasty photokeratitis and potentially permanent corneal damage but that’s the sort of thing that can potentially be fixed by surgery (unlike retinal damage from visible wavelength lasers).

People always look at me weird for picking up peoples old microwaves off the curb or trash. Those parts inside are awesome for HV experiments and the transformers alone are worth the time.For dielectric check out baking supplies. They make silicone sheets for lining baking trays for large sheet cakes. These are not the thicker ones made for re-use but disposable so are really thin. Sizes easily available are 16 x 24″, 30 sheets for $5http://www.amazon.com/Silicone-Parchment-Sheet-Pan-Liners/dp/B00086IB5CAnother option is using plain clear silicone caulking. Put some cooking oil on two pieces of metal . Put a bead of the silicone down the middle of one piece and put the other piece of metal on top. Weight it down or stand on it to flatten it till the silicone squeezes out. Let it dry then pull the metal apart and you will have a paper thin sheet of silicone for dielectric.For rails try copper water pipe. It is very hard, straight and two pipes placed parallel have an almost perfectly straight path for the spark to jump across. You can also solder the plate directly to it if you use copper plates for the base.",

Building A Power Supply Around A DC-DC Converter

The EEVblog is on a roll with interesting topics lately. In the latest episode [Dave] takes us through
the nitty-gritty of switch mode power supply design
. Using DC-DC converter IC’s in not especially hard. The datasheets tend to have fairly good usage schematics but there’s always a bit of heartache that goes into figuring out which external components will make for an optimal design. Get your calculator out and, in the video after the break, he’ll walk you through choosing component values based on the formulas for the MC34063 converter chip.
[Dave] makes the point that this is an extremely common chip, available from several manufacturers, and often found in consumer electronics. In fact,
the switchmode supply hack from last month
was using a regulator based around the MC34063. So you can buy it or scavenge for it. One thing to note though, we checked Mouser and Digikey and they’re pretty short on these chips right now. Plan your projects accordingly.

This
art piece makes drawings based on sound
. [Mario Marchese], who is responsible for
those illusion props back in february
, built this little guy out of a bunch of junk he had lying around. It features four microphones that listen to ambient sound and feed the signal through some LM386 audio power amplifiers. The output is translated into forward, backward, left, and right movements of the writing platform while the pen is fixed in the same position. Despite what we said in the title of the post this isn’t strictly a CNC machine, but more the primordial cousin of one.

Cheap Cable Reused To Add USB To Your Project

You get what you pay for. [Jkx] wanted to see how a USB to RS232 cable could be sold for just $1.70 and found out that it’s not actually RS232 compliant. The cable communicated as TTL levels, not the 12V expected of RS232 (although it can handle 12V incoming). He didn’t really want to use them for their intended purpose anyway. By betting rid of the DB9 plug and reusing the enclosed circuit board he now has
a really cheap way to interface a microcontroller with the Universal Serial Bus
. He worked out a couple of short subroutines that take care of receiving and sending data over the connection.

So why did he even bother ripping the cable apart? Many µCs come with USB these days and I heard some have even software implementations bitbanging it. Native USB is far more flexible than abusing rs232 (over USB) for binary communication anyway. I might be biased since I only recently started working with µCs and I’ve only had some stm32 (arm cortex m3) so far, which are pretty powerful and have easy to use native USB…Greetings from Germany,DekarThis is pretty lame IMHO.",

This was an eye opener as my standard rule of thumb was $20USD.Also the fact that some cheaper cables do NOT have any true RS-232 level shifting but have the inverted polarity was completely new to me and this will really change some of the advice I offer on some of the electronics forums.One other thing I would point out is that there are some micros that allow the polarity of the UART to be inverted. This hack then would allow the hardware UART to be used without having to add a “MAX232” etc. Many of the newer PIC chips have this feature.All in all, I found it an interesting hack.",

When doing posts like this it would help if you spend a bit of time looking into it yourselves and then presenting more detail and a bit of an overview. That would stop people moaning and make HAD a much more useful resource.ATM you basically just post a bunch of links every day. Anyone can do that. Electronics Lab at least filter their posts so we only get the really good stuff that actually presents something new. I’m not saying be just like them, but if you did more editing and editorial I think it would improve HAD a lot.On the subject of USB->RS232 one of the best options is a Nokia CA-53 cable. They all use the same PL2303 chip (drivers built in to Windows 7 and Linux) which is a pretty good little device. It is 5V tolerant even though it runs on 3.3V. The DA-53 cables usually have everything contained in the USB end and you can either crack it open and solder on directly or cut the Nokia end of the cable off and use that.With AVRs you might not even need a level shifter, especially if all you want to do is receive. The AVR’s inputs have diode clamps anyway. In fact Atmel have an app note where they connect 240V mains directly to a pin with only a 1M resistor to limit the current! A similar resistor, say 10k, works well with RS232. Many USB converters and motherboard serial ports will work with TTL levels for reception too so you may get two way comms for the price of a couple of resistors.",

"content": "Honestly, I’m starting to wonder why we ever bother with serial anymore.I’m beginning to look into ARM based processors, and I’m finding that they all have builtin USB and its not that tough to use. You can get 55MHz ATMEL SAM7s processor for $2 in an easy to solder package (SMT soldering is NOT hard! I just learned it from watching youtube videos).There are already EAGLE footprints for some nice mini USB connectors in the SparkFun Library, and there are a few Atmel libraries that contain the SAM7 parts on the EAGLE website. Then you can send your PCB off to batchPCB for a few bucks and get yourself a very nice, easy to use board.There are some examples on the web for how to start off with them just acting like a USB COM port, so you can still code for the PC the same way, but there’s actually less stuff to solder. USB only requires two resistors, and they usually recommend one cap on the power line. Those SAM7 ARM chips don’t have much to hook up in EAGLE and you can get an example schematic from OLIMEX.I haven’t had a lot of time lately but I’m pretty much convinced that I’m ending my use of 8 bit processors as soon as I start my next project. 32 bit just isn’t that complicated anymore.Maybe I’ll write a tutorial. I really want to teach! Don’t wait for that though, just follow my advice here!-Taylor",

Keypad Door Lock, Better Than Last Years Keyfob?

It’s that time of the year again. The leaves are changing colors, it’s getting colder outside, and all the littler hackers are off to college. Which means we get to see an influx of dorm room locks and openers.
[Adam] is back at it again with a new
keypad dorm room lock
. Last year he had an exceptional setup
using a car keyfob
, so we’re a little curious as to why he would revert to such a low level system as a keypad that
isn’t even color coded
.
Perhaps its in his “new” way of presenting the hack. Rather than a blog or write up, he documents the
entire
most of the process in a little
less than 20 YouTube videos
. Watch him testing out the system after the jump.

Macro Lens For A Nexus One

"headphone",
"jack",

"macro",
"putty"

[Thomas] tipped us off about
a macro lens attachment for his Nexus One
. As you’d expect, adding the lens helps the phone’s camera bring tiny details into focus. He re-purposed a lens from a pair of mini binoculars, using epoxy putty to make a mounting bracket. Now the last time we saw this putty used with a phone it was for
a snap-in bracket that cradled the phone
and included a lens adapter. Rather than go that route [Thomas] made use of the headphone jack just above the camera lens. An old headphone plug has been epoxied to the macro lens ring, holding it in place securely while remaining easily removable.

How often does this happen to you? You’re leaving on a long trip, and half way there you remember the TV was left on. Never? Alright then, how about wanting to control an Xbox 360 from within the other room and you don’t have the remote. Still a rare occurrence?
Perhaps you have a better situation where an
internet controlled IR remote
, that can be programmed to work with any TV or IR accepting device, would be useful. [Nicholas McClanahan] starts off with USB Propeller from Parallax, adds an Ethernet module making a mini server, and ends with an IR LED and receiver. The code is nearly as simple being a combination of
SPIN
, Html, and JavaScript. All coming together under a nice website GUI that prompts for what IR signals to send. To make the project even more straightforward, [Nicholas] has included an
Instructable as well
. In the end though, while the hack is great, we’re still trying to find a decent enough use. Video after the rift.

And clearly, if the prototype was subject to such scrutiny, it would fail largely because the digi-amino-responders show no indication of a channel redirecting jigatron.

Then when your significant other inquires about the “bing,” you open the compartment on the device, revealing the M & M. Then you offer to give her the M & M if she agrees to change the channel. I think there is a definite market for this type of device. The coding is relatively simple. Actually, the code is “English-basic” and consists of the following command: “change the channel.”",

PVC Pipe Fittings Just For Building Stuff

If you’ve used PVC as a building material in your projects you may have run into trouble finding a way to make three pipes joint at right angles to each other (like the corner of a box outline). That’s because there’s no need for that type of joint when plumbing, the intended purpose of the PVC pipes. But [John] tipped us off about
FORMUFIT PVC Fittings
designed for construction use instead of plumbing. There’s a lot of interesting options, such as the ninety degree connectors, rounded end caps for aesthetics, and end caps designed to receive casters. We also enjoyed seeing the T connector that slides onto a pipe and can function as a swivel. We haven’t tried them out ourselves, but we think they’d come in hand whether you’re building
complicated moving structures
or just making a desk.

But please don’t go pubicly partying about the cheap price of PVC without mentioning the reasons. It was born as waste, and it will end up in waste.I think toymakers in the US and Europe had to get rid of PVC. (Good) Computer makers are stopping using it. The EU is talking about making it an illegal material as a whole.

PlayStation 3 Exploit Using A TI84 Calculator

[Brandon Wilson] came up with a way to
exploit the Play Station using a TI84 calculator
. This uses the same
PSGroove open source code
that we looked at last week. That package was running on the Teensy,
which is currently sold out
(we’d guess because people want to run the exploit). There’s a video demonstration of this new trick after the break. The calculator connects via a USB A to USB mini-B cable which comes with the calculator and is also used to charge the PS3 controllers. Once the connection is made, launch the software on the calculator, power cycle the PS3, and turn it on with the familiar power-eject button presses. The only problem with the system is that the calculator needs to be connected every time you boot.

Controlling a long-range unmanned aerial vehicle is much easier if you have
an augmented reality system
like [Fabien Blanc-Paques] built. On board the aircraft you’ll find a sensor suite and camera, both transmitting data back to the operator. As the title of this post indicates, the display the operator sees is augmented with this data, including altitude, speed, and a variety of super-handy information. For instance, if you get disoriented during a flight there’s an arrow that points back to home. There’s also critical information like how many milliamp-hours have been used so that you can avoid running out of juice, and GPS data that can be used to locate a downed aircraft. Check out some flight video after the break.

Constructing A CO2 Laser Cutter

[Owen] contacted us to show us his site dedicated to his
CO2 laser cutter build
. He spent about 2 years and roughly $15,000 putting it together, so this is not small build. The laser and optics alone were $9,000. This site isn’t necessarily meant to be a template to build your own, but he shares so much information that we would certainly suggest you read it before digging into a build. He does have some downloadables, like the tool paths and the emc2 configuration files as well as a copy of the entire website. Great job [Owen].

If not, it’s goingto create safety issues, and under some faultconditions, you’ll have the outer conduit betweenthe sub, and the “appliance control” panel “hot”.(ie. touch it, ground yourself, die). Reason NECwants grounds extended from the main to a sub (inthe same building). And unless he left the cover offfor the picture, it’s definitely a hazard withoutthe protective cover.In one picture he says he tore out the brick (atthe base of the laser supporting frame), and putrebar down before pouring a slab. But if you lookat the pic, it shows the rebar, and the brick isstill below it. It does show some ‘efflorescence”(ie. moisture issues). Long term, probably a badidea pouring concrete over it, but given it’s nota house foundation, it’s no big deal for a simpleslab supporting shop equipment.Why is asking “how much did it cost?” (in his FAQ)a “rude question” ?",

I could have poured concrete on the brick, or the dirt, not sure moisture issues would be really different.Its a rented house so I dont go too crazy on building for my life time.

Like how the millennium falcon was just a big pile of junk, but was still a very capable spacecraft. This certainly isn’t a pile of junk, but at first glance you may not notice. When our technology gets complex enough, it becomes possible for one dude in his basement to build an extremely high powered laser cutter. 20 years ago this would have been in a very expensive lab environment if it were even possible, and this guys just got his in a grungy basement.

Web Controlled Watering Can
|

"potentiometer",
"power window",
"watering can",
"webkit"
] |
Here’s a watering can and water vortex that are
controlled with a webkit browser interface
. The interface displays a drawing of the watering can on your browser. If you grab one of the handles on the circle around the image and move it, the can will rotate as well.
Okay, so this isn’t going to change the world and actually presents a fairly useless watering setup. But [Ben] seems to be a master of fabrication and that’s what we appreciate in this build. The watering can is solidly mounted and moves fluidly with seemingly little effort from the motor. He uses a spring to keep the rope loop taut, sourcing a castor wheel and automotive power-window motor to provide the motion. The hinged base on which the can sits has a potentiometer in it, used to measure the current position of the watering can. Remember these techniques as they’ll come in handy in your future builds.
There’s also a little bonus at the end of the video after the break. We wondered what [Ben] might use that
power drill controller hack
for. Looks like it makes an appearance in his water vortex work.

Laser Cutter Doubles As A 3D Printer

[Bart] figured out how to
use his laser cutter as a 3D printer
. We’ve checked in on
his open source laser cutter
in the past and we’re happy to see he’s now done with the build. But rather than stop there he took it a step further. For less than $200 he built an extruder head and added RepRap circuitry. You can see in the image above the laser tube is in the background and the extruder head with a line of black filament is mounted on the gantry. [Bart] has other plans for extensibility as well, including a knife cutter, a pen plotter, and a Dremel mount.

76 Flaming Trombones Led The Big Parade
|

[
"Musical Hacks"
] |
[
"flame thrower",
"propane",
"red rot",
"trombone"
] |
[Jonathan Crawford] is ready and willing to fire things up with
his flaming trombone
. A couple of years back his band teacher was going through the storage room triaging instruments. This trombone suffered from a bad case of
red rot
and would never function well again so [Jonathan] was able to get his hands on it and get to work.
He started by sanding down the instrument and painting it with high-temperature spray paint. Flexible copper tubing intended for an ice maker was used to relocate the propane outlet inside the bell of the instrument. A barbecue igniter, controlled with the player’s left thumb, lights the flame.
The torch that [Jonathan] is using would only allow a small amount of gaseous propane to come out the nozzle. He ended up drilling out the aperture, and using a short piece of vinyl tubing to bridge the gap between the nozzle and the supplementary copper tubing. At full blast this allows liquid propane to escape so be warned.
You can see him demonstrating this indoors in the video after the break. He mentioned to us that the first time he tried this out he set off the smoke detector. You’ve got to be careful when playing with fire, whether it’s a musical instrument, or
a wearable flamethrower
. So, you know, don’t try this at home.

RFID Entry Uses Homemade Electronic Strike
|
Mike Szczys

"555",
"deadbolt",
"electronic strike",
"rfid"
] |
[Fileark]
built an RFID entry system
that uses a pretty ingenious alternative to an electronic strike plate. An electronic strike is a rather expensive hinged plate that mounts in the door frame and catches the door latch. But this system opens a set of double doors. The door without the handle is fixed in place and has a normal strike plate. But it also has a deadbolt mounted in line with that plate. When the deadbolt is extended it is flush with the strike plate, pushing the latch from the door knob back and freeing the door to swing open. This is a bit hard to put into words so watch the video after the break to clear things up.
The system uses a cheap RFID package that provides a single signal line. This line connects to an old VCR motor which turns the deadbolt. Timing is provided by a 555 chip, and the deadbolt movement is limited by a couple of switches mounted along with the motor.
Now that the unlocking mechanism has been built it would be simple to use other authentication methods for unlocking the door, like
a wristwatch-based proximity system
.

Also the MOD’s are more for use, it’s no longer connected to a car computer (if you open it, the Yellow is connected to 2 pins, one of which is a special data pin that when used in it’s intended purpose it will send a unique serial data stream depending on which known fob was used). Also the unmarked IC is a UM3758-120AM encoded/decoder chip. The reason for the removed pins from the chip, it appears to prevent re-encoding the master chip and to control the output to instead of a unique serial stream now just an on/off stream.Also found another mod for this device:http://home.btconnect.com/QTEKNOLOGY/rfid/RFID_new.htm",

Irongeek.com is hosting an
online class on password exploitation
. The event was a fundraiser called
ShoeCon
, but they are hosting the entire series for everyone to share. Not only are the videos there, but you can download the powerpoint slides as well. There is a massive amount of information here on various topics like Hashcat, OCLHashcat, Cain, SAMDump2, Nir’s Password Recovery Tools, Password Renew, Backtrack 4 R1, UBCD4Win. There’s so much info, they split it into 3 sections. The videos are fairly long, between 1 and 2.5 hours each. What might surprise people is the amount of time that google is actually one of the main tools.
These videos can be a fantastic resource for hobby hackers, IT admins, and security professionals.

Revive A DockStar And Get So Much More
|
Jakob Griffith

[
"classic hacks"
] |
[
"dockstar",
"jtag",
"parallel",
"tiao"
] |
[Firestorm_v1] has done a fabulous writeup on not only resurrecting his
dead DockStar with JTAG
, but also includes some handy techniques and useful information that could be used with other hardware and
JTAG equipped devices
.
The tutorial itself goes into the details of finding the JTAG, correctly identifying the ports and making an adapter cable. Then wiring a
TIAO Parallel JTAG
kit and finally the flash and upload of firmware to the deceased Dockstar to give it new life.
While the fun stops a little short, we’ll be sure to keep an eye out for [Firestorm_v1’s] future plans involving these surprisingly useful (read: hackable)
storage devices
, “roving USB camera with WiFi” we hear?

Here’s a great tutorial on
building your own quadrotor helicopter
. This build isn’t necessarily less expensive than
others we’ve seen
since quality motors, propellers, and control circuitry aren’t cheap. But the design and assembly is well documented and presents a well-planned building procedure. The carbon-fiber tubes that make up the frame have extensions to protect the motors and propellers in the event of a crash. The Arduino, IMU, and transceiver are all tucked away between two aluminum body plates as well. They only thing missing is a solid methodology for tuning the four motors, a critical procedure that is just touched up at the end of the article.

[Ryan O’Hara]
built a location tracker
he could use on motorcycle trips. Ostensibly this is to give his wife piece of mind be we think that was an excuse to play with GPS and SMS. To stand up to the trials of the road [Ryan] took his breadboarded prototype to the next level, using a manufactured board and a SparkFun enclosure. Tucked safely away is a PIC 18F25K20 gathering longitude and latitude from a GM862, formatting the info into a Google Maps link, and sending it to
the Twitter feed
via an SMS message. If you’re not familiar with the GM862, in addition to being a GPS module it can send and receive cellular data on a GSM network.
This is a nice solid hardware platform from which we can envision a couple of other hacks. The feed could be parsed to make a nice map graphic like the webpage for
that Twittering Road Bike
. It also might be nice to have a d-pad and character LCD to post your own tweets to the feed at the end of the day.

Steroscopic Rig Requires Only One Camera

[courtervideo] shares an instructible with us on how to build a
mirror rig to take stereoscopic pictures with one camera
. We’ve had the thought “couldn’t you just do that with some mirrors?” when looking at a
dual camera rig
. Well, as we all suspected, you can. There are some advantages here, a single click gives you your 3d image or video without any post processing, and unless you just happen to have an extra camera lying around you can save money there. You do however lose some resolution compared to two separate cameras. This setup could actually add some steps if you were wanting to interlace your images for viewing on a 3d tv.

Because viewing ‘flat images’ with just one eye open is much the same as seeing it like a camera lens sees it. The informational cues are there (depth of field, etc.) and the mindis able to matrix the information and create the optical illusion of depth.Try watching TV some time with one eye shut. It’s especially effective in close-up scenes with a lot of objects at varying distances and you’ll especially notice it when you see graphics superimposed over a commercial, for instance.",

Serial Port Controlled CPU Fan

[Christian] was running a Linux box as a home server but
needed a way to quiet the noisy machine
. Like many Linux servers, he’s using some pretty old hardware which doesn’t have an on-board header for the CPU fan which generates much of the unwanted sound. Those headers are nice because software can monitor the CPU and board temperature and adjust the fan accordingly.
[Christian’s] solution was to use the serial port for the task. He built a small circuit in which serial pin 3 drives the base of a transistor, pin 5 provides ground, and a floppy drive power cable supplies 5 volts. From there he wrote a RUBY program to monitor the CPU temperature and generate a PWM signal on the serial port, throttling the fan speed as needed.

We must find out where you can acquire these industrial robots pictured above. Sure, you expect car companies like BMW to have a few lying around, which they used to make into a
Twitter message writing robot
. But Bungie, a video game company, to have one as part of an
advertisement for Reach
?
The former is just a scratch on the surface, with
some pictures
, but a much more decent writeup will be provided after September 12th. The latter has a
few videos
, and you can watch it recreate a
monument with light ‘live’
. And while both are impressive uses of old tech, neither answered our first question, we gotta get us one of these.

Their robotics studio software is extremely easy to learn and their Rapid Code is almost just plain English and yet massively powerful. A couple of months ago I saw one with 200kg payload rating go for €8000. That compared to the starting price for a bad boy of that size being more like @50,000 – €100,000.On the other hand KUKA robots are more awesome and kicks a lot more ass. (Not at all biases because I will be a programming intern at KUKA for 9 weeks this fall.)",

Not trying to be a Debbie Downer, but here are some things to watch out for when trying to acquire old equipment.Even if you are able to purchase (or even get for free) a used arm, controller and (highly unlikely) all the appropriate cabling — you still need the software to make the thing work. Further supposing you manage to get the controller with a working hard drive with operational software on it; you still don’t have the motion control development system…that was on a computer that’s either still at the arm’s former home, or in a separate dumpster somewhere else.Getting the development environment is the Achilles heel here. You almost need insider help for that, because you almost certainly can’t afford to buy it, even if the manufacturer still offers it for sale, and even if they would sell it to you. And the software is probably licensed and locked, so a bootleg copy, even if available, would need to be cracked.Pendant programmable machines may be a viable option, *if* the pendant was included with the arm (probably not, because one pendant can be used with multiple machines and they probably didn’t dispose of all of them at the same time, and kept the pendant, or the pendant went to whoever bought the first unit for a higher price.",

Manuals, software, hardware, pendants, cables, everything. Even some contacts with the guys that coded the units in production to pick their brains. Essentially you’re buying the units at scrap rate when they’re untested at closeout/auction. The problems for me though was power and space. Usually these things require 440 3-phase at some pretty healthy amperage. Even if you can get the juice to run it, my other problem was space. The vertical reach on the ones I could have gotten were higher than the rafters in my garage. So yeah, even if you do get all of the goodies, power can be a problem. If you can get tiny ones (less than 3′ reach) usually you can get 220V single phase servo controllers and you can cobble together a replacement controller software system. For the big boys, it just didn’t seem worth it. :-(",

I know one guy who is powering a 125kg payload Kuka from a single phase to three phase inverter in his garage without problem. You are quite right about the cost of used units though robots do tend to retain a good percentage of their value throughout their lifetime.In the photos it is apparent that there is no safety guarding, this is because it is in a controlled environment. Robots are very dangerous and the chances of an unexpected movement in this project are increased because each character position in the sequence is calculated with an offset against the work object of the whiteboard. An error in calculation could see the robot veer in any direction, or even into itself!On the day it will be properly secured with guarding and will be nowhere near any person!Early on in development we did have some comedy pen/whiteboard smashing incidents but as any robot programmer will tell you that is just par for the course!Keep watching for the complete technical write up to be published on my blog.Matty",

What do you do after you make a
BeagleBoard graphing calculator
? [Matt] over at Liquidware Antipasto made a
BeagleBoard Elastic R Cluster
that fits in a briefcase. Ten
BeagleBoards
, are connected to each other though USB to ethernet adapters and a pair of ethernet switches connected to a wireless router. The cost for this cluster comes in around $2000 and while consuming less than 40 watts of power, out-paces a $4500 laptop. How might you use this cluster? What improvements would you make?

Face-slapping Security Gaff In Stored-value Cards

The laundry machines at [Hans Viksler’s] apartment were converted over from coin operation to stored value cards. We’ve all dealt with these cards before and [Hans] thought it would be fun to do a little
sniffing around at how this particular company implements them
. We’ve covered
how to read these cards
and there have been several stories regarding
how to bypass the security
that they use.
But [Hans] wasn’t interested in stealing value, just in seeing how things work. So he stuck the card in his reader and after looking around a bit he figured out that they use the Atmel AT88SC0404C chip. He downloaded the datasheet and started combing through the features and commands. The cards have a four-wrong-password lockout policy. He calculated that it would take an average of over two million cards to brute force the chip’s stored password. But further study showed that this is a moot point. He fed the default password from the datasheet to his card and it worked.
We know it takes quite a bit of knowledge for the average [Joe] to manipulate these cards at home, but changing the default password is literally the very least the company could have done to protect their system.

For everyone using a later version of Windows like Vista or Windows 7 they will probably never get to enjoy the awesomeness that was Wing Commander…
until now
. [Jari Komppa] has managed to use DirectDraw to his advantage and hack out a solution to this disappointing problem. He used DirectX to do this and has even managed to get OpenGL to load from a DLL after a few problems with Windows XP and Windows 7. This is truly a step forward in retro gaming. No more should we have to load a virtual machine to play Starcraft. Hopefully getting this ported to even older games such as Sim Farm or Commander Keen are on the way!

Projectile Speed Sensor

[Mike] built
a sensor rig to measure projectile speed
. The setup uses a tunnel with two sensors in it. Each consists of a laser diode on one side focused on a photodiode in the other. The two are monitored by an op amp and measured by an ATmega128 microcontroller. When the beams are broken the elapsed time between the two events is measured in order to calculate speed. There is a setting to adjust the calibration for a range of speeds, which came in quite handy as [Mike] initially tested the device with rubber bands before moving on to a pellet gun and then a rifle.
It seems like he’s tempting fate by shooting a target just a few inches below his exposed circuitry but his marksmanship prevailed. We’ve seen bullet speed detectors in the past, used just for the delight of seeing
how fast the projectile is moving
, and also to
capture an impact at just the right instant
.

The closer your sensors to the muzzle, the easier it will be to consistently have shots that will break the beam. Also, testing at a shorter distance from the muzzle will minimize the effects of external ballistics on your rounds (density, temperature, humidity, pressure, wind), which will make it easier to confirm your results with published data.“That is, when they would fire – a number of them were just a bit too long to fit completely in the chamber.

The
Equinox clock
is made up of simple parts but a combination of fine design and precision make it a gem of a timepiece. The guts are made up of an Arduino, a DS1307 real time clock, twelve LED drivers, and sixty RGB LEDs. These combine with a capacitive touch interface to tell the time using three lit blocks for the hours, one for the minutes, and a fading block for the seconds. See for yourself after the break.
To our delight, [Bram Knaapen] shared
the specifics of the case
. The black ring that makes up the body was laser cut and spray painted. He uses small blocks of acrylic that have been sandblasted to diffuse the light. This is also a great example of clean circuitry using interconnects between the different circuit boards.
We always enjoy seeing clocks
no matter what level of finish is involved
, but great design is something that makes us want to hang a project on the wall rather than stow it in a parts bin.

1953 Radio Includes Tubes, AM, FM, And MP3

This
vintage radio can play AM, FM, and MP3
, all with a classic sound. Inside you’ll find a new AM radio tube-amp, providing the functionality you’d expect from the device. The rest of it comes from a conglomeration of parts; an FM receiver board from another radio and an MP3 player with remote control and USB connector. The classic sound we mentioned above comes from an AM modulator. That’s right, the auxiliary audio boards aren’t connected directly, but are broadcast on the AM band so that your latest MC Lars album has the same sound quality as the traffic report.
Check out this similar project from last year that
adds RDS to a vintage radio
.

Snake Bot Climbs Trees
|
Caleb Kraft

"Robots Hacks"

"snake",
"tree"
] |
While you are out enjoying your Labor Day festivities, keep an eye out for robot snakes in the trees. The CMU robotics lab has
built a snake bot named Uncle Sam that can climb trees and poles
. As you can see in the video after the break, the bot seems to have no problem at all scaling a tree. It wraps itself around the tree, then rotates down the center of its entire body. Once it has reached the top, it can take in the scenery. Though it is a little creepy looking, at least it isn’t in the water.

The year is 1988
, where a Russian engineer [Vladimir Demin] has combined a Bayan, or button accordion, with several (we lost count at about 96) solenoids. If that alone doesn’t blow your mind the computer, also hand built by [Vladimir], controls the whole process leaving the operator to only work the bellows.
Putting truth to the fact in Soviet Russia, accordion plays you
. We wish we could find some more information about the instrument, but curse our inability to read Russian. Alas check after the break for a shorter version of the video in the link above.

Solid Ice Beer Caddy

"ice"
] |
[Rob] has made an astounding contribution in the effort to keep our libations chilled. Not content with merely refrigerating his cold ones, or even putting them in a cooler full of ice, he has
built a beer caddy out of solid ice
. Though it may look simple initially, you can see from his writeup that it actually took quite a few itterations to get it to freeze correctly, and then actually survive the process of removing the bottle placeholders. Ultimately, he found that glass bottles full of sand work best and you have to freeze the caddy in layers. Though he calls himself an impatient person, we’ve seen people who insisted on having their
cold ones made frigid faster
. You can see a video of the ice caddy after the break.

Ergo it might have to work harder to stop food from freezing.As for the pool/beach – good luck in getting it back again, or are you going to go to the trouble of making one of these every time?Beer fridges are 12V DC by design, so run off a car battery. Even if you keep it connected for the journey and unplug it once you’re there, you’re still getting chilled beers at the end and since it’s completely enclosed, will do a far better job at keeping your beer cool.

[Syst3mX] emailed us about his
Binary Calculator
earlier this week and it almost slipped into the depths of our inbox. Luckily We noticed it in there today and thought we’d share.
He wanted to be able to calculate binary values without having to jump through hoops or boot up his computer, so he built his own binary calculator. For the brains, he chose an ATTiny2313. He can do basic operations like NOT, AND, OR, XOR, addition, subtraction, multiplication, division and modulo. It isn’t too bad looking either. You can catch a video of it in action after the break.

We didn’t believe this hack at all when we saw it, or rather heard it. Surly a
guitar made out of a shovel
couldn’t sound decent. But the video (after the jump, skip to 2:40 for the jam) to our untrained ears sounded pretty rad. Could be the supremely well done wood work, proper use of tools, high tech pickups, or maybe Russian magic, we don’t know.
In fact, if you continue the video it doesn’t stop there. The creators also made a 2 string bass and a few other instruments from shovels. Do I smell a new shovel hero?

should not be guitars

Meter Clock Using The TI Launchpad

"launchpad",

"msp430g2211",

Here’s an
analog meter clock using an MSP430G2211 microcontroller
. [Doug Paradis] chose this processor because it is the lesser of the two that come with
the TI Launchpad
. The parts count is fairly low too; a clock crystal, two analog meters, a few buttons, and a voltage regulator.
He’s done a nice job putting this together. We challenge you to give this a try yourself and build on [Doug’s] features. We really liked the calibration subroutine in
[Alan’s] multi meter clock
. It would be fun to implement that functionality and store the calibration code in the MSP’s flash memory. You can use
our ported garage door opener code
if you need an example of how to store data in flash.

Firmware Hacking On Behringer Midi Devices

"behringer",

"midi"
] |
A new project called
the Unofficial Behringer Control Development Kit
lets you tweak or completely replace the firmware on the popular devices. The proof of concept demo shows a custom message scrolling on the 4-character 7-segment display but you can do with the device is only limited by how well you can code for the ARM processor inside. Development takes place using the
GNU ARM toolchain
but don’t worry, you don’t have to crack the case open to program the chip. The BCR2000 and BCF2000 models supported by the project both run bootloaders that allow firmware updates via midi commands. There’s even a recovery mode if you screw something up. Just make sure you have a direct midi connection for recovery, the USB port won’t work for that purpose. If you need a shove to get you started there’s
a nice little example file
in the repository.

Meat Smoker Texts You When It Is Done
|

[Peter Rauch] has built this
meat smoker that has a touch screen control interface
. His system is capable of controlling the cooking by monitoring the internal temperature of the smoker as well as the temperature of the meat itself. His touch screen interface allows him to enter his desired parameters and it basically just takes over from that point and texts him when it is done. You’ll have to
download the pdf
to get to the juicy details of his build, but it is an interesting read.
It looks like he’s using a 4-loop Gefran GFX4 temp controller in conjunction with a Modbus remote terminul interface and a TS8010 HMI touchscreen for the bulk of the electronics. It even has protection limits he can set to keep his family from bumping it up to 1200 degrees.

The trick will be to control the vent(s) via some some sort of servo mechanism (which will be big, bulky and hard to mount). And yes, the first trick is to master heat control manually and get to know the characteristics of your smoker. I use a Big Green Egg and find that the bottom vent is the “macro” adjustment while the top vent is the “micro” adjustment. I have had a PIC based wireless temp monitoring solution up and running for years – the beauty (as you know) is that it frees you up to do other things besides babysit your smoker to make sure the temp does not run wild. My setup uses 430mhz wireless com modules but I have been thinking about porting it all to an Arduino/WiShield solution for WiFi enabled monitoring (thing 3G iPhone monitoring while I run to the local Safeway to pick up coleslaw materials to cap off the perfect smoked pork meal).Nice work!",

Whenever someone manages to expose vulnerabilities in everyday devices, we love to root for them. [Adrian] over at Irongeek has been inspired to
exploit barcodes
as a means to attack a POS database. Based on an idea from a
Pauldotcom
episode, he set out to make a rapid attack device, using an LED to spoof the signals that would be received by scanning a barcode. By exposing the POS to a set of generic database attacks, including
XSS
,
SQL Injection
, and other errors easily solved by input sanitation, he has created the first version of an automated system penetration device. In this case the hardware is simple, but the concept is impressive.
With the hardware explained and the source code provided, as well as a basic un-sanitized input
cheat sheet
, the would-be barcode hackers have a great place to start if they feel compelled to provide a revision two.

Our initial view
of the Spy Video TRAKR “App BUILDR” site had us believing this would be an internet-based code editor and compiler, similar to the
mbed microcontroller
development tools.
Delving deeper
into the available resources, we’re not entirely sure that’s an accurate assessment — TRAKR may well permit or even require offline development after all. Regardless of the final plan, in the interim we have sniffed out the early documentation, libraries and standalone C compiler and have beaten it into submission for your entertainment, in order to produce our first TRAKR hack!
TRAKR software development at the moment, to phrase it just as politely as we can, has a Wild West flavor to it. The finished tools and reference materials aren’t expected until October. Early documentation is rough — entire sections still missing — so it’s frequently necessary to rummage through their example code to learn how things operate. And the compiler is
exceedingly
rough right now…it requires a minor patch just to get started, and works only within
Cygwin
, a UNIX-like command shell for Windows systems. So tonight we’re gonna program like it’s 1999! To continue, we’ll have to assume you’re at least vaguely familiar with command-line development tools, as explaining the entire process from scratch is more than we can fit here.
It probably goes without saying, but for posterity: these are beta tools and the entire process will almost certainly change as the TRAKR HAKR site nears release, rendering these directions obsolete. Until then, for those wanting to get an early start, here’s how we began building our own TRAKR hacks…
Getting the compiler
The C compiler and documentation are presently located on the
Apps Help page of the TRAKR web site
. Just follow the directions there to download the App Primer (containing the compiler and demo source code), the TRAKR Codebook PDF (an introduction to TRAKR programming), and the Function Reference and code snippets for lighter-weight reference once you’re familiar with the concepts.
The Apps Help page states that the tools work with Linux, but this isn’t entirely true. The App Primer ZIP file contains only the Cygwin (Windows) toolchain, along with the TRAKR libraries and sample code. The C compiler is based on arm-elf-gcc 3.4.6 — Linux users might stand a chance with the pre-built 3.4.3 package from the
GNU ARM
web site. You’ll still need to download the App Primer for the libraries. With Mac OS X, things get ugly…we’ve yet to locate a viable package for Intel Macs. Building the 3.4.6 toolchain from source (or via MacPorts) has brought only frustration, and the TRAKR makefiles don’t play nice with later (but working) arm-elf-gcc editions. Joy. Eager to move ahead, and not wanting to invest a lot of time on beta tools that are certain to change, some of us are simply using the Windows package in
VirtualBox
for now.
Getting the compiler
to actually work
After unpacking the App Primer ZIP file, copy the TRAKR.1 folder inside to a suitable working location within your Cygwin directory. The _MACOSX folder can be deleted — this is just an artifact of the files having passed through a Mac at one point; there are no OS X build tools here.
Just unpacking the Primer and trying to compile the examples, you’ll encounter a slew of “undefined reference” error messages and a failed build. There’s a problem with the TRAKR library — some test data that’s not properly archived — but it’s a straightforward fix. Go into the Internals directory and edit the Makefile using vi (or another editor of choice if you have one installed). Line 22 looks like this:
OBJECTS = $(S_OBJECTS) $(O_OBJECTS)
It should be changed to this:
OBJECTS = $(S_OBJECTS) $(O_OBJECTS) $(O_IMAGES)
Save the changes and exit the editor, then (still in the Internals directory) type:
make trakr.a
Now you can go back to any of the examples and successfully compile by typing “make”. For example:
cd ../EX06_Sound
make
This will create a “.bin” file that can be loaded onto the TRAKR. Attach a USB cable between your computer and the TRAKR vehicle (the power switch can be on or off, it doesn’t matter). In a moment, the TRAKR’s internal storage will show up as a small removable drive. Then just copy the .bin file to the APPs folder on this drive, e.g.:
cp EX\ Sound.bin E:APPs
Disconnect the USB cable, power up the TRAKR and remote, press the remote’s Home button and use either stick to navigate to the “EX Sound” menu item, then press the “Go” button. The app should prompt you to record 10 seconds of audio from the TRAKR’s microphone, then plays this back. Cool stuff!
Writing your own apps
Each TRAKR app is required to have three functions: Start(), Run() and End(). Your Start() function contains one-time initialization code, such as opening the motors to software control; End() is the complimentary function for when your program finishes, restoring control to normal TRAKR operation. Run() contains the meat of your application…this function is expected to return either “true” or “false” to indicate whether it should run again iteratively, or is ready to exit.
The header file svt.h contains constants and prototypes for the functions described in the Codebook and reference documents. This includes high-level functions for producing graphics and sound, turning the
infrared LED
on or off, reading the controls, driving the motors and accessing the SD card. This is all the
Official Documented Stuff
thatApp BUILDR will encourage us to use.
But there’s a second header, JAPI.h, revealing much of the underlying functionality on which the TRAKR library is built. And for the time being, this is the only way to access the really interesting stuff like digital I/O, video processing and USB host. This is most definitely
not
the Official Documented Stuff, and relying on it now means your code will probably require some changes to work with the Official Stuff later.
There’s something conspicuously absent from both libraries: higher-level digital I/O such as serial
UART
or precise
PWM
control. We’re not even certain yet whether any the accessible breakout lines correspond to these hardware functions. Maybe it’s something forthcoming, or maybe this will require the chip datasheet, with code talking to the registers directly. Worst case, such I/O will just have to be done with slower
bit-banged
methods. Which is exactly what we do with…
Our first hack
We really wanted to showcase both the software and hardware hackability of the TRAKR. There isn’t the space for an overly-technical writeup, but neither do we want to send you off with a trivial modification. Hopefully we’ve found a good balance here…mildly esoteric, but most readers with modest prior soldering and programming experience should be able to follow along and create something similar.
Our inspiration came from
an earlier Hack a Day article about the txtBomber
, a handheld dot-matrix graffiti printer:
The width of the TRAKR is about the same as a sheet of paper. With
a row of solenoids
and some paint markers, we could make a fantastic mess with this…or even simpler, skip the markers and head to the beach, having the TRAKR “comb” messages in the sand.
Problem is, we didn’t have a stack of solenoids on hand, and we wanted to get right into this rather than wait around for parts to arrive. Rooting among the detritus of our
secret underground vault
, we found a great substitute from a prior project: a row of 48 addressable LEDs driven by
shift registers
, the board on which they’re mounted perfectly matching the TRAKR’s 10 inch width! So our aim now was to achieve the same effect in light. The TRAKR moves too slowly for retinal
persistence of vision
to occur, but we could use
long exposure photography
to capture the results.
Anyone can buy a TRAKR off the shelf now, but the light bar was something custom-made for a POV project. The good news is that it’s
a very common circuit, something we’ve linked to before
, and a slightly scaled-back version can be built on a breadboard. Ours has a set of six 75HC595 shift registers with decoupling caps, each driving eight LEDs with associated current-limiting resistors. Very similar to what’s shown in that article, but cascaded out to six chips. You could also do something similar (and
way
more colorful)
using ShiftBrite LEDs
.
The LED board is held to the ’bot with masking tape. Spared no expense!
As pointed out in our
teardown
, the all-important JACK3, containing the GPIO lines, is smack dab in the middle of the TRAKR main board. The unpopulated header USB2, which we’ll use as a power tap, is closer to the outside edge.
In our haste to create a presentable demo, we just soldered wires directly to the TRAKR’s circuit board, but at some point intend to dismantle the thing again and solder on a proper header for inserting wires. For +5VDC and ground, the VDD5V and VGND pads of the idle USB connector are used. The shift registers require three data lines (as we’ll explain in a moment), and we opted to use the first GPIO lines on the board, labeled GPC0, GPC1 and GPC2.
The shift register interface, referred to as a
3-Wire
serial connection or sometimes SPI (Serial Peripheral Interconnect), is a
synchronous serial
interface, meaning that each bit of data is accompanied by the synchronized tick of a clock bit on another line. A third line, called the
latch
, signals the end of the data transmission — in the case of an 8-bit shift register, this will output on its 8 parallel data lines the last 8 bits that were “clocked in” over the serial connection.
For our light bar hack, we’ll use GPC0 as the clock line, GPC1 as the data line, and GPC2 as the latch. Most microcontrollers feature some kind of native 3-Wire/SPI support, but as mentioned earlier, with the TRAKR library at present we’ll have to trigger all these bits through software control.
Next thing we need is an image to display on the LEDs, one row at a time. Naturally, we’re going to use the Hack a Day logo:
In the source code archive provided later, the image is present as a 1-bit Windows BMP file, simple to work with because the data is uncompressed. The image is turned sideways as it requires less code for the program to decode each horizontal row of the bitmap than it would for processing vertical columns. It’s 48 pixels wide, corresponding to the 48 pixels in the LED bar, and 60 pixels high, including some blank lines at either end so repeated logos don’t run one into the next.
Our example program is hardcoded for this one demo image, which is embedded in the executable. A more sophisticated program might allow the user to load an image from the SD card, and would properly parse the BMP header to query the actual image dimensions. Again, we’re just looking to keep the code simple and not stretching out to hundreds of lines.
// POV demo for Spy Video TRAKR w/shift register LED bar.
#include "svt.h" // Official API
#include "JAPI.h" // Secret sauce
#define ROWS 60 // Image height in pixels
#define COLS 6 // Image width in bytes (pixels = 8x this)
#define PAD (3 - ((COLS - 1) & 3))
extern unsigned char _binary_logo_bmp_start[]; // In logo.o
#define CLOCK (1 << 0) // GPC0
#define DATA (1 << 1) // GPC1
#define LATCH (1 << 2) // GPC2
void Start()
{
JAPI_SetIoOutputMode(CLOCK | DATA | LATCH);
}
bool Run()
{
unsigned char *ptr, byte;
int r, c, b;
// 62 byte offset to start of image data within BMP:
// 14 byte BMP header, 40 byte DIB header, 8 byte palette
ptr = &_binary_logo_bmp_start[62];
for(r=0; r<ROWS; r++) { // Each line in image
for(c=0; c<COLS; c++) { // Each byte in line
byte = *ptr++;
for(b=128; b; b>>=1) { // Each bit in byte
if(byte & b) JAPI_SetIoLow(DATA);
else JAPI_SetIoHigh(DATA);
JAPI_SetIoHigh(CLOCK);
JAPI_SetIoLow(CLOCK);
}
}
JAPI_SetIoHigh(LATCH);
JAPI_SetIoLow(LATCH);
Sleep(20);
ptr += PAD; // BMP rows start on 4-byte boundary
}
return true;
}
void End()
{
}
The graphics-related #defines should be clear by now, we know this program is set up for this one specific image. The CLOCK, DATA and LATCH #defines correspond to the individual bits passed to GPIO-related functions, making subsequent code easier to read.
In the Start() function, the call to JAPI_SetIoOutputMode() initializes all three lines as outputs.
Because of the way the image is formatted, there’s minimal work now to be done in the Run() function. For each horizontal row of the image, six bytes of image data are output one bit at a time, 48 bits total: the DATA line is set either high or low to indicate the corresponding 1-bit pixel value, and then the CLOCK line is quickly toggled high and then low to “clock out” the data bit. At the end of each row, the LATCH line is similarly toggled to tell the shift registers to display the new data. A 20 millisecond delay holds the image for a moment so it’s not all scrunched together, given the TRAKR’s limited speed.
The next line advances the image pointer to the start of the next row, if required. In BMP files, rows are always a multiple of 4 bytes wide. Our bitmap is only 48 pixels (6 bytes) across, so this skips the two extra bytes at the end of each row. The final “return true;” line tells the TRAKR library to repeat our Run() function again indefinitely.
The End() function is empty for this program, but it still needs to be present to keep the linker happy.
A ZIP file containing the above source code, bitmap image and makefile can be downloaded here
. Extract this archive within the Trakr.1 folder, alongside (not within) the Internals directory. “cd” to this directory and type “make”. If all goes as planned, this should produce the file POV.bin, which can be loaded on the TRAKR as described earlier.
Something to consider when hanging circuitry off the TRAKR is the proximity to the 2.4 GHz antenna. We wasted a good half hour tracking down a “software bug” that in reality turned out to be our sloppy, long wires picking up radio interference (you can still see a few whacked-out pixels in the image above). Keep wire runs as short as possible, perpendicular to the antenna.
Bright future
Even in this early stage, warts and all, we’re quite excited by the prospects for this toy’s hackability. Wild Planet is to be applauded for their open-minded approach in encouraging software and hardware modifications. A lot of comparisons are already being made to the
Roomba
and
Rovio
, both of which have spawned enthusiast sites and even books. Time will tell if the Spy Video TRAKR catches on the same way.
So that’s our TRAKR hack…now let’s see yours! When you’ve got something cool to showcase, don’t forget to
tip us off

If you are running an app from the SD card when you exit it the menu no longer shows apps on the card. I tracked that down to a bug in the trakr.c file in Internals.The function SVT_Log_Close() doesn’t close the file system. Just add a call to SVT_FileSystem_Close(); and that fixes it.You don’t need to include the image dir for the missing image objects, they are only used in the test.c app in the internals dir and if you remove the refs to image0, etc. from svt.c and svt.h you no longer need thoses object files.Last thing (I promise) be careful using the 5V supply with the GPIO pins, those are 3.3V I/O’s and could be damaged by a 5V signal. The same goes for the AIN4 pin. (Which works great, gives a value from 0 to 1023 with 0-3.3V in)Sorry for the long post. Thanks again for the great work!Joe C.",

When the tipline popped up with
this LED suit
,
part two
, by [Marc DeVidts] we were expecing a simple led version of the previously known
EL coat
.
Well we were right and wrong in the same instance. Correct in that like predictions, the outcome is
stonking great
. Wrong in that this suit far outpaces EL in abilities we weren’t expecting. Namely to start off, an iPhone app over WiFi dictates to some 200 Arduino multiplexed RGB LED modules to dance randomly or follow patterns; an accelerometer and microphone are also implanted to further some effects. And finally if the suit isn’t enough to make you giddy, his PCB and enclosure milling surely will. Catch a video of the entire setup after the break.

Alarm Clock Learns New Trick, Opening Doors

"door",

Waking up at 5:30 in the morning. [Mark Stead]
didn’t like the idea
either when his chickens started crying to be let out. One simple solution obviously is to
eat the chickens
build an
automatic door opener
. The mechanism starts out with an old style mechanical alarm clock, add a geared motor with some creative switch work to pull open the door, weather proof the entire thing, and done. [Mark] even modified the setup later to work with
vertical doors
. No MCU required for either.
Pair this with an
automated feeder system
, egg gathering and cooking setup, and you’re half way to having your breakfast ready for you when you wake up in the morning – around noon like the rest of us.
[Thanks MS3FGX]

C Sharp Development 101 – A Tutorial Series
|
Greg R. Jacobs
|
[
"Software Development"
] |
[
"c sharp",
"c++",
"programming"
] |
In this tutorial series we are going to look at C# Development using the Visual Studio 2010 Express editions. This will take you from the basics of installing Visual Studio 2010 Express, to the Object Oriented Programming style associated with C# and other languages, dabble in some database access (Access & SQL Server Express) and finally, design a project that will pull all of our knowledge together into a final solution.
We are going to begin by downloading the Visual Studio 2010 express from Microsoft’s
website
so that we can get started on some C# development. After the file has been downloaded you will need to have a connection to the Internet so that the program can download the necessary files to complete the install. For the sake of customization we won’t walk through the rest of the install and will pick up with some add-ons that will make your coding experience easier.
With the Express edition now installed, it is good to know that the express editions of Visual Studio 2010 do not support extensibility. This means that the ability to install plug-ins and add-ons is not included. If you happen to acquire or have a full version of Visual Studio 2010 then the option is there for you to add these plug-ins that have helped me out in a tough spot before.
Visual Assist X
This is probably one of the best applications out there for intellisense and document syntax highlighting. Now many of you might be saying that Visual Studio already does this. Yes they do, but not as well as Visual Assist X. This add-on will look into your added in files such as the Boost library, and retrieve all of the Boost functions and try and piece together a description of what that particular function would do. Syntax highlighting is the best around with the quick option to do minimal to maximum highlighting. A must have for the avid programmer but will run you $249 for a one year subscription and $49 maintenance fee every year afterwards. This price tag might discourage most but take the 30 day trial and take it for a test run.
Ghost Doc
A product of SubMain, this add-on will allow you to document your code quickly and efficiently using XML markup. To generate these comments it uses the elements type, parameters of the function as well as its name to generate the comment. This is especially useful for people who do not enjoy documenting functions in their code. Most promising add-on if you are looking for code documentation.
AnkhSVN
A free SVN add-in for Visual Studio that allows you to connect to a repository, browse the branches all within the comfort of the Visual Studio environment. Very easy to use for people who want to start a community project on Google Code or host their own. A must have for people who like to collaborate and don’t want to hover over one persons computer to review code.
All of these have been personally used and are highly recommended for use when developing for the .NET framework. The next part in this series will go back to an old classic for programmers; Hello World. We will go through making a project file and printing Hello World to the console as well as on a form. As always, any problems with the series or if you just have questions post to the comments so that we may learn from each others mistakes and grow as a community. If you can’t wait until the next post,
here
is how to start making a Hello World console app. Until next time, Happy Hacking!

I don’t care how “Nifty” it is.The problem is like dealing with DirectX, if it locks you in to one vendor it’s a BAD THING.Whatever the merits are of C# they are outweighed by that simple fact. C# could be the end all super fantastic wonderful language from heaven, Tie it to M$ and it’s just another useless non-standard standard.I’m sure to get flamed by all the people who have serious investments of time, but I have been programming for 30 years, I have seen them come and go and Proprietary is ALWAYS BAD. Breaking standards, splitting groups dissension etc… The fact that it splits us here is more than enough to shy away.Java’s ability to run on multiple platforms has effectivelyunified all the UNIX flavors, and has allowed some software companies todeliver to both UNIX and Windows customers. This is the greatest challenge to the Microsoft dominance of PC-based software.Thus the REASON behind C#. If I can’t cross compile it’s not of any use to me. Yes there are some C# compilers under development for Nix environments, but they are fare from cross systems compile ready.Anyway I haven’t seen anything in C# that would make me sacrifice the ability to compile for multiple systems. What happens when you want to compile a version for some future PDA android type pad etc. or just for Linux Unix or even Mac? Your screwed. Might as well add some libraries in C++ to do the same functions and wait for the C# fad to pass.Sure you can run Mono(.NET for nix) but do you rally want to deal with M$ and it’s whims, which often are deliberate attacks on open systems, described nicely in the infamous M$ Halloween letters?",

Admittedly, I have only dabbled in C#, so my observations might be somewhat limited.I absolutely love the managed allocation concept in C#, it’s something C++ should adopt natively as a standard. Even C++ CLI is ok (which is what I use for some projects), but the syntax can be a bit hairy.The extensive use of namespaces (as opposed to header files declarations) in C# .NET libraries are well organised too. Again, I wish C++ compilers would use this concept.Getter/setter methods rock.That said, I’m not too enthused about having both class declarations and implementations in one big scope. Things get a bit messy when you have huge classes to deal with. (Maybe this is something I need to brush up on?)VisualStudio Express seems to be quite slow when dealing with C# source code, which annoys me.The #1 thing that really annoys me is the lack of native code generation in C#. Not a fan of MSIL at all, and quite frankly the JIT compiler doesn’t even start to compare with natively compiled C++ code in terms of CPU performance. While this may not be a big deal if you do mostly GUI programming, but for things like serious CPU based data processing, it doesn’t cut the mustard.",

[Harvey] wrote in to share
the Spindicator
with us. The spindicator is a hard drive activity activity indicator built in a ring to resemble a dekatron. Using the pulses from the hard drive activity LED, [Harvey] tested several different methods of interpreting that data for display. The final version, negative edge triggered with a lowpass filter can be seen after the break. It is nice and smooth and vaguely reminiscent of many programs’ loading screens.
He has pictures and tons of detail on the project including videos of previous versions that acted quite erratically.

EEVblog Dissects A Kindle 3

[Dave] over at the EEVblog did a review of the kindle 3 recently, but never got to the good stuff, the guts. He is now rectifying this with a
full video dissection of the eReader
. Full of details on how to open it up as well as specifics on the internals, this is a fun video to watch. One thing that caught our attention was the RFID tag on the inside of the case. It is probably for inventory tracking, but we can’t help but have a few tinfoil hat type thoughts. You can watch the video after the break.

For those who do fancy photography, setting up the lighting ends up being one of the larger tasks of each session. There are flashes out there that can be controlled via a remote control to help ease the process, but they can cost a considerable amount more. [Dsvilko] shares with us a fairly simple circuit that allows you to
use a tv remote to control your flash
. He’s using a picaxe 08m and he states that before this project, he had never messed with microcontrollers. We say great job on your first microcontroller project. You can catch a video of it in action after the break.

You have until December 1st to get your entry into the
Trossen DIY robotics contest
. Unlike the last
Trossen contest we told you about
, this one has no clear theme. The goal is simply to make an awesome robot. Registration is free, and entries will be judged on Ingenuity, Originality, and presentation/documentation. There are prizes for 1st, 2nd, and 3rd places, with the 1st place prize being the Interbotix Hexapod. If you haven’t seen it yet, it is a kit of a hexapod that is pretty quick on its feet. You can catch a video of it after the break.

[Sk3tch] rigged up a way to
use an original NES controller with Android
. He bought the controller and a breakout board for it at DEFCON. By combining the controller, an Arduino, and a
blueSMIRF BlueTooth module
the controller can be used as a keyboard on his Android device. In the video after the break he demonstrates pairing the devices and playing Super Mario Bros. 3 in an emulator.
He calls this Alpha quality but it certainly looks like it works well. In the beta version we’d love to see all of the extra electronics inside the controller case like
those USB mods
.

[Ben’s] added some nice goodies to his Volvo in the form of
an in-dash computer
. The system monitors two pressure sensors for boost and vacuum, as well as reading RPM, O2, and exhaust directly. All of this is tied into the touch interface running on an eeePC 900A. But our favorite feature is that the system requires you to enter a PIN to start the ignition. The forum post linked above is short on details so we asked [Ben] if he could tell us more. Join us after the break for a demonstration video as well as [Ben’s] rundown on the system.
[youtube=http://www.youtube.com/watch?v=_yPlFFCGi2A]
Ben writes:
Hi, great, glad you like it. The EEE 900A has a 2GB ram upgrade and a 16GB SSD upgrade, running windows 7. I modified the computer so it could fit directly behind the screen, which involved relocating the USB ports, and also using a HP webcam from a broken laptop as a back up camera.
The black box has three circuit boards. I’ll send you some pictures of the most current version later. The first board is for power, It has a 3.3v and 5v regulators to provide the two voltage rails, and the three relays. One relay controls the power supply to the netbook, the second controls the car’s actual starter, and the third controls the auxiliary power and lighting system.
The second board uses two freescale semiconductor pressure sensors, one to read boost and the other to read vacuum. It also has a secondary microcontroller (A PIC18F2550) to read a direct RPM input as well as a wideband o2 sensor in the exhaust. This uC is running in i2c slave mode.
The final board in the back is a PIC18F4550, which has direct control over the relays, the secondary controller, and also directly reads the two pressure sensors. Both controllers run software written in PICBASIC.
Now the part that I like about the interface box, is in order to talk to the computer, it uses only the PIC18F4550’s USB port. one usb connection is all that the computer talks to the car with.
The software running on the netbook is an application that provides a front end to the control box, A PIN is required to be entered, and once the PIN is correct, you are then able to start the car via the
button on the screen. The normal key method of starting no longer works. For security, The interface ONLY sends the PIN number to the control box, the control box has a PIN number saved and encrypted on the PIC’s internal eeprom. The entire application was written in VC++, .net, and provide me with accurate boost, vacuum, RPM, and AFR on screen. Touching a gauge on the screen enlarges it, and minimizes the other two gauges for enhance readability.
It’s all cleanly installed in my 1998 S70 T5, which was an automatic from the factory and that I swapped to manual in January this year. To power the entire system on, you only need to press the unlock button on the keyfob. by time you get to the car, the computer is running, and the control box is connected to my software and waiting. Locking the doors via key fob (using the key on the door also works just as well) tells the contol box to use a transistor to electrical press the EEE’s power button and put it into sleep mode. Once the EEE is off, it cuts power to the EEE, and then both controllers go into sleep mode, drawing minimal current. I’ve left the car for a couple weeks with the entire thing hooked up, got home, and started it right up and drove away. I designed the entire system like any company would, to ensure reliability. There are safety measures that only I know about, that allow me to re-enable the standard key ignition in case of an emergency.

"content": "He guys, thanks for all the comments. I’m the creator of this thing, and I figured I’d clarify some things. The car still requires a key, I didn’t want to disable any of the immobilizer features. The control box has two inputs it checks to prevent any mishaps. One, is it can tell when the engine is running, and second it reads the RPM. The hardware WILL NOT allow the starter to engage while it has a engine running signal or if it is getting any RPM signal (except during the initial cranking). Also, like someone brought up, when the control box knows the engine is running, it also will not power down any of the systems, so the door locks are essentially disengaged in regards to the control of power for the computer and control box.No, the EEE is not doing a full boot, I kept the original battery, and relocated it in the car, so the EEE is usually in standby, unless the car is left alone for a couple days, then the computer will actually have to do a full boot.So yes, the ignition key must be in the second position, the third position (start) simply is disabled, and control of that is passed to the control box.",

"content": "First of all cool project! I have been thinking about doing something similar to my truck.Second, the key kills the engine and locks the steering column as he demoed it. If the computer dies while the car is running it will not affect the running engine (at least not from what I see in the demo). Good thing since it’s a Windows system.Basically he has cut the starter wire and spliced it into the computer. The problem is this is not real security. It is a trivial matter to start a car with just a screwdriver or two or a jumper wire.The starter has +12 straight from the battery, all you need to do is apply power to the ignition circuit (by popping the ignition and turning to ‘run’), then apply +12v to the starter solenoid and viola running car ready to drive.In order to foil thieves you would need to do more than that by cutting power to the ECM (Engine Control Module), Injection pump (if electronic), or some other much more obscure method. Want to get really fancy? Cut the feed from the TCM (Throttle Control Module) too. Then even if they manage to get it started it will only idle. Think defense in depth!The best method to secure a vehicle would be to re-write the ECM code to require a ‘PIN’ to allow the engine to run (Many Semi’s use this technology). But of course if I really want your car I just bring my own ECM, unplug yours and plug mine in (the one I bought at the junk yard).This will prevent the joy riders, but not a serious car thief. They can always resort to a car hauler / Tow Truck.However, I would never install a Windows OS in my truck. How embarrassing to get a BSOD when I change a gauge display or . . .I intend to build mine on Linux and Incorporate GPS, Backup Camera, Forward Facing Camera, all data available on the CAN bus will be logged as well as mp3 player and probably a few other things as well.",

How To Fix AVR-SIZE On Ubuntu 10.04
|
Mike Szczys
|
[
"News"
] |
[] |
The program avr-size is part of the AVR-GCC toolchain used to develop programs for that line of microprocessors. The program tells you how much space the code will take up on the chip, important information if you’re trying to cram a program into a small program memory. Perhaps more importantly, it shows you how much ram is being used. This is the “Data:” portion of the image above and if you overflow the memory this will be the only thing that lets you know that has happened (except for unstable behavior once the program is running).
For quite some time the avr-size package in Ubuntu has been missing a key feature that makes the information more human readable. [Jeff] over at mightyohm tracked down the solution to the problem on the bug tracker and posted the
directions on how to bring your copy up to date
. Basically, download the package from Debian (an upstream copy that has already been patched) and install it. [Jeff’s] guide is based on the AMD64 version so we’ve copied his procedure in a more generalized fashion after the break.
1. First,
go here
and download the appropriate package for your architecture. The most common is i386 and you should download the most recent revision number (2.20.1-1 at time of writing).
2. Use the Debian package management system to install the package you just downloaded (you will need to change the package name if you didn’t download the i386 version):
sudo dpkg -i binutils-avr_2.20.1-1_i386.deb
3. Place the package on hold to prevent automatic updates that actually downgrade back to the broken version:
echo "binutils-avr hold" | sudo dpkg --set-selections
That’s all there is to it. We like to use a makefile written as a WINAVR example to compile and upload our AVR code. We’ve made the changes necessary to use the fixed avr-size program.
Download the makefile here

[Devon Croy]
built a case to join a webcam sensor with a camera lens
. The box is a PVC conduit box you’d find at a home center. He used JB Weld to attach four bolts to the back of the box. These are used to fine-tune the mounting plate for the webcam sensor to ensure it’s at the focal point of the lens. The lens connects through a couple of extension tubes to an adapter mounted in the center of the box’s cover plate. The setup above shows a macro lens that
takes pretty good pictures
.
If you need images of really tiny things you should look into
a microscope adapter for your camera
.

Open Source Version Of The Play Station 3 Jailbreak

Don’t steal. It’s a lesson that children are taught from the youngest age and a core principle in every society.
The PSGroove
sets out to follow this mantra in several ways. It is an open source implementation of
the PSJailbreak hardware
we covered a couple of weeks back. It’s difficult to find a definitive source of information on that hardware but
many have speculated that the original device contains stolen code
. Whether that’s true or not is moot as the PSGroove doesn’t include the backup manager program alleged to violate copyright.
The device is also aimed at running homebrew, and doesn’t natively allow one to play backups. It runs on a variety of AVR hardware, including the Teensy boards. If you have one of them, it’s just a matter of compiling the code and unlocking the potential of your PlayStation 3.

This part of PPC code acknowledges the USB stick by sending it a message, indicating that it successfully started running injected PPC code. After that, it jumps into the “payload” code which is what patches game OS to enable “install package” and the virtual disc mounting – and that payload code is specific to the PS3 firmware version.So, I observed that it did run the first part of the exploit because the PS3 signals the USB device. After that it hung. I am thinking that replacing the payload code with a Linux bootloader would be the proper route for complete independence from both gameOS firmware and the piracy stuff.",

Replacing The Driver Board In An Old-school Door Chime

[Dan Kouba’s] parents replaced their doorbell button with one that lights up and found that the chime wouldn’t stop sounding after the button was pushed. These lighted buttons use an incandescent bulb in parallel with the button (a piece of hardware
we’ve hacked in the past
). It draws a small amount of current which isn’t enough to trigger the chime, but it is just enough that the chime unit reacts as if the button press never stopped. His parents asked what he could do about this and after some investigation he build a replacement board for the chime unit based around an ATtiny26L. The board monitors the voltage drop across a resistor in the doorbell circuit. When the comparator on the AVR detects a rise in the voltage drop across the resistor it rings the chimes, actuating the solenoids with a set of PNP transistors. [Dan] sent us all of the details which you can check out after the break.
Dan writes:
My parents have this really old door mechanical chime that they got as a housewarming gift 25 years ago, and recently when they replaced the doorbell button with a newer lighted one, the bell wouldn’t stop chiming. Apparently the light in the button passes enough current through it while its on (and the button is unpressed) that it triggers the bell over and over again. They didn’t want to get rid of the doorbell, as the newer electronic ones just aren’t the same, so I was asked to see what I could do about it. My solution was this project.
The old chime system consisted of a motor, which would be set into motion by pressing the button, and a set of contacts which the motor would revolve around and trigger the four solenoids that ring the chimes. Once I disassembled it, the cause of the infinite cycle was obvious. The motor’s start current was higher than the light in the bell would permit, but once it was triggered once by pressing the button, the bulb current was enough for it to remain in motion. There wasn’t a whole lot I could do to fix the old system, so I designed a microcontroller based replacement.
I used an Attiny26L (admittedly overkill, but it was all I had on hand) for the brains of the operation, a button press detector made out of a comparator and a resistor (more about that in a second), and four transistors for triggering the solenoids. Those parts along with the power supply (there was 20VAC available at the wall) fit onto a radioshack PCB which happened to fit perfectly where the old system had sat. The old system had the option to either chime a sequence or only a single chime when the button was pressed, and I replicated this feature in software using the large blue DIP switch shown in the pictures.
My detector circuit is simply an 82 ohm 5W resistor inline with the button/light combo. The button and the light are in parallel, so there is always some current passing through the line, causing a small voltage drop across the resistor. When the button is pressed, the light is shorted out and the current becomes much higher, thus causing a higher voltage drop across the resistor. I used a comparator attached to a voltage divider reference (half the supply) and to the resistor. That in turn is connected to the AVR which monitors for the button press and triggers the chime accordingly.
One of the problems I ran into was that the solenoids are high side switched. One lead of each solenoid is attached to the case, so unless I wanted to run 4 more wires, I had to use PNP transistors to switch them (I would have used MOSFETs, but I had the transistors in my parts box). I used an NPN transistor to pull their bases low so switching from my 5V AVR was easier.
The code is really simple; it’s just an infinite loop watching the comparator output for a trigger, and after that it triggers either the chime sequence or the single chime based on the switch input. I was originally going to use interrupts, but I had issued with multiple triggers. The interrupt flag was cleared as soon as the ISR was being processed, so if the bell was pressed twice before the chime sequence was finished, the interrupt would trigger a second time once the ISR finished its first run. A simple if…then statement fixed the problem.

Making A Smaller Keyboard

The keyboard on [Marek’s] laptop stopped working. He didn’t want to buy a replacement so he decided to start using an external keyboard. But hauling around a full 104-key model is a bit of a pain so he decided to
make himself a shorter keyboard
. He basically chopped off the 10-key pad on the right side of the board. This had the unexpected consequence of removing the screws that hold the top and bottom of the case together so he ended up adding a few extra screws to shore it up. You may be wondering how the key matrix still works if a portion of it has been cut off. [Marek] used the simple trick of folding the extra part of the membrane over and covering the unused contacts with some tape.
If you try this you should consider getting rid of the directional arrows and editing keys as well. There must be a way to map those keys elsewhere. Perhaps the
half-qwerty keyboard hack
will give you some inspiration for that.

I can, I didn’t spend a dime, and you can hardly tell by looking at it, to boot.If it looked like a bailing wire, duck tape, zip tie hot glue hack I’d be just as happy. The point is, it WORKS.

Wearable Controller For Your Paintball Tank

If you’re too frail to take the full impact of a paintball round let
this tank
serve as your surrogate. The camera perched on top of the platform feeds video back to the operator’s head-mounted display. Instead of using a joystick or other traditional controller, the user aims by looking around, with his or her head movements mimicked by the camera and barrel of the tank. It looks cooler than it sounds so jump with us after the break to see for yourself. If you’re playing against this thing, we’d recommend aiming for the camera lens.

Here’s
a great magnetic levitator build
. [Scott Harden] dug up the link after seeing
that awesome rotating globe
this morning. This version hangs objects below an electromagnet but it has a sensor system to provide a constant distance between magnet and object even if the payloads are a different weight. This is done with a couple of infrared sensors. One acts as a reference detector, always viewing an IR LED in order to get a baseline measurement. That measurement is compared to a second detector mounted slightly lower. The circuit adjusts the electromagnetic field, making sure the object is always breaking the lower beam but never interrupting the reference beam. No microcontroller needed, this is handled with a couple of OpAmps. See it in action after the break.

DWex Watch Looks For Future Development

[FlorinC] sent in his
DWex Arduino watch
, with intentions for it double as an experimenting base. Inspired by the
MakerBotWatch
, it runs an ATmega328P, DS1337 RTC,and 24 LEDs to display the time. [FlorinC] tells us the (yet to come) case and strap will be similar to
Woz’s watch
to ensure airport security tackles him
. As for experimenting, the PCB contains an ICSP6 and also an FTDI connector for those “other-than-watch purposes”. We’re not all sure what else could be done with a watch; we racked our brains and came up with a compass, but with the source code and Eagle files available maybe you have a better idea?

Hotel room door lock picking
Here’s further proof that you should never leave anything of value in your hotel room. We’re not worried about someone getting in while the room is occupied. But these methods of
defeating the chain lock
and
opening the door without a keycard
(YouTube login required) do show how easy it is for the bad guys to steal your stuff.
iPhone frequency generator
Need one more way to make that iPhone a useful lab tool? Why not
use it as a frequency generator
. Start with a free app and mix in an audio cable with test leads and you’re in business.
Drag Soldering
[Andrei] sent us a link to a video about drag soldering. This is a method of soldering fine-pitch chips using a small bit of solder and a fat solder tip. The link he sent is dead now but we found
another great example of the process
. We were just using this method earlier in the week to
solder a TSSOP38 package
for an upcoming project and it worked like a charm.
Laser etched PCB
Here’s some
art in PCB form thanks to a laser
. We thought this might be interesting to share after seeing those
art pieces made from old circuit boards
. This example is laser etched, but not directly. As you probably guessed, the copper clad board is coated with resist and the laser etches some of it away. Whatever got zapped by the laser dissolves when the board is placed in acid, leaving [Riley Porter’s] art behind.

The trick is to use a good temperature controlled iron, fine gauge solder(practicing to only feed *just* the right amount), and *generous* amounts of good liquid flux(but not TOO much). For extremely fine-pitched packages, you can solder a few pins at a time(however many the width of the soldering iron tip will reach) by dragging away from the pins instead of perpendicular to them. With good flux, and good precision hand control, you really only need to touch the flux, and not the pins themselves.@MS3FGX:Hopefully, anyone that would need to use this would construct a simple buffer/isolation circuit for use when driving circuits that will sink more current than the phone can source. Hopefully… :)Also, MS3FGX, what does your name mean?",

I those cases, though, you would likely be able to use reflow if you are building your own circuit(for initial placement, and not replacement)…@Osgeld:Don’t “sideways-sweep” fine-pitched QFPs, pull away, like I said. You can “side-sweep”, but you must be careful to use the flux as your thermal conductor, and not actual contact with the pins. Otherwise, try pulling away from each set of pins to solder the chip(after you have tacked down the corners) using lots of flux, and if you don’t apply too much solder, you should never have bridges. I have replaced dozens of 304 pin QFPs using this method. FWIW, removing the old chips(I believe mentioned here before) for those high-density packages can be easily done with an Exacto knife with a dulled down tip, by rocking and cutting your way through the top of the pins, and then removing the legs with a soldering iron after the epoxy chip casing has been removed…",

And guess what: I’ve always drag soldered them and never ever did I have to fix a bent lead.By the way. You don’t really need to touch the leads. You just drag your soldering iron at the ends of the leads, over the pads. The solder will cover the pads and come in contact with the leads of the chip. It will immediately heat them up and flow around them. When you get to the end of the row, you just wick up the excess solder, if necessary.",

[Gavilan Steinman] just
printed and assembled his own RepRap machine
and filmed the process. This isn’t news but we found it very interesting to watch. He started with
a RepStrap
, a rapid-prototyping 3D printer that as built by hand instead of printed by a similar machine. This is the seminal step in the self-replicating process.
From there he prints an extruder head which improves the quality of the parts the RepStrap can produce. We then see time-lapse footage of the printing process for
a Mendel unit
, the second generation of RepRap machines. We’ve embedded the video after the break. It’s a great way to spend ten minutes on a Sunday afternoon.

If he had put just a little more time and effort into the original build, there would be no need for it to build parts for the improved version. It seems like people get a little too wrapped up in the idea of self-replicating machines.On the other hand, machines like this are excellent for one-off items or objects intricate enough to make hand fabrication impractical (well, at least, sufficiently annoying).",

Not only that, he printed a new extruder for the old unit, to help print out quality parts for the new one. In addition to that, he shows that the old one was crafted out of wood using hand tools. He saves a lot of time, increases accuracy, and probably has a better setup going than if he would have taken the time to mill it out of aluminum and other parts.He did very well, and made the video an excellent showcase to what he did. I hope he adds more to the build layout so maybe others can replicate it. It looks very nice, and is an excellent example to what a reprap can do.",

The Makerbot and UP printers have approximately the same resolution (as do the much more expensive Stratasys machines). However, the UP and Stratasys have larger print volumes, which allows parts to be printed larger, and therefore, to have a higher signal-to-noise ratio in the finished print.You do bring up a valid point, however – Repraps and Makerbots allow control of all print parameters, which means that they also allow operators to get any of these parameters wrong :) Since most of these machines have only been in the wild for a few years, most makerbot and reprap operators have less than 100 hours of printing experience. This combination of high control and low experience means that lots of prints made by the open 3d printing community are lower quality than they could be.When you buy into a proprietary print system, with proprietary plastic material, you get higher quality output, and you sacrifice some of this control.As other people pointed out though, you also sacrifice the community, and the innovations made available by the community. I doubt very much that the UP printer people will make an improved extruder head design available for free, every 4-6 months (as the reprap community has done for the last 4 years).In my opinion, this alone makes open printers worth the time it takes to learn to use them well.",

[Ken] needed to supply 3.3 volts of regulated power. He started by using a linear voltage regulator but after a few calculations he discovered that 72% of what he put in was lost to heat. The solution to this is a switched-mode power supply. Rather than burn off energy through a voltage divider, an SMPS turns the power on and off very quickly to achieve the desired voltage.
A car charger-type USB regulator was chosen as [Ken’s] donor device. He figured that
making adjustments to the resistors inside would affect the output voltage
and he was right. He adjusted the potential divider and ended up with a steady 3.295V.
We asked him to share the schematic that he put together from studying the board and he came through. See that and get the link to the DC-DC converter datasheet after the break.
Above is [Ken’s] hand drawn schematic. After conversing with him about this project he grabbed a jeweler’s loupe and was able to identify the DC-DC converter in the circuit. It’s an MC34063 whose
datasheet can be found here (PDF)

A lot of the recent (2000+) chips make it extremely easy. The datasheets are very well documented and include example circuits and all the equations you could ever want. Very few modern chips have any sort of loop compensation issues to worry about, meaning they work with virtually any inductor and capacitor. Seriously, don’t be afraid of these circuits, go try it!",

Fine, you know the inductance, and the max current. But that’s usually the max current due to ohmic heating, and not core saturation which tends to happen first. Likewise, for flyback converters B-H curves are rarely given. That part is a real PITA.Although, one partial solution to both of your qualms:Look up Coiltronics’ “Versa-Pac” inductors/transformers. They’re coupled inductors normally in the $5-10 range and the datasheet is decent. The really nice part is they can be used as both inductors and transformers, and different arrangements give you some flexibility in prototyping. They’re still pretty bad for flyback though, so you’ll have to stick with the standard buck/boost topologies. Isolated you’re limited to forward.",

"content": "While the efficiency of switching regulators can be quite good, the transient response of switching regulators is usually not anything to be proud of, especially with an impulse or step response. Such is the price of things obeying the law of “you can’t get something for nothing” Depending on the circuit and the type of low-pass filter on the output there can be some serious overshoot/undershoot, ringing, and delay before the voltage settles to the correct value, which is why switching regulators are usually pretty bad for hifi audio. A good way to test the response of a supply is to get a simple FET or BJT, drive the gate/base with a square wave, and have a low value resistor in series between the supply output to be tested and the collector/drain. Watch the supply voltage on a scope, you will see what I mean about ringing and overshoot/undershoot.If your application can tolerate this, there is no problem.",

[Theo Kamecke] is an artist who
produces striking pieces using printed circuit boards
. We’ve seen
PCBs used as faux stained-glass
before, but [Theo’s] craftsmanship stands apart from everything we’ve seen. His webpage has at least one piece that sites the usage of vintage 1960’s circuit boards, but we wonder if he doesn’t design some of these to suit his work. Either way, we’d love to see him take on the finish work for that
mechanized expanding round table
we saw back in June. See more of his work on
his photostream
.

Seaswarm: We Can Clean Up The Gulf In A Month

Want to clean up the Gulf of Mexico oil spill in one month? Seaswarm says
it can be done with 5000 floating robots
.
As the name implies, the project uses swarm robotics. Each unit draws power from the sun, and drags around a conveyor belt of
oil absorbent
nanofabric
that doesn’t get wet in water. Once the fabric is saturated with crude it can be removed using heat; not a task the swarm can do by itself. But get this: after separating oil from nanofabric both can be used again. That means you get the environmental benefit of cleaning up the Gulf, not throwing away your collection medium, and the oil is once again a usable commodity. Sounds like a lot of high promises, but take a look at the video after the break and decide for yourself.

Then that unit is useless until it is picked up out of the gulf, taken apart, processed, put back together, and dropped back in the gulf. Also, from the build quality and considering the gulf with hurricane season and sizable waves, I think we’d up with oil-covered SeaSwarms washing up on the shores, with spare parts being found inside the stomachs of marine life…I don’t think they took into account such time and logistics… seems like they just took a time of absorption for an amount of oil into the fabric and extrapolated it out to a month.I’d say it’d be best retrofit the ships we already have – they have speed and lots of power available. Build something more than just the nets they use now, perhaps a lot of the nanofabric, and then pull it in with the winches and wring it out… wash, rinse, repeat. Could be implemented much faster, and all that is needed is some sort of pasta roller like machine to heat it and extract the oil.",

And it could also heat and extract the oil into it’s own tanks that can then be pumped into ships when full. A larger device would be more seaworthy, and wouldn’t have to return to land to be processed.If oil producers worldwide had a couple of these each, they could easily take care of their own minor spills quickly. But when a major spill occurs, send as many of them as could be spared to where they’re needed.A great discussion, which was spoiled when..“Mirra” said“Since when are you americans started caring about the environment?”then “truth” said“The U.S. is the only country on the planet right now which cares about the enviroment.”and“Look at what crap-holes Asia/China and Europe are turning into. Guess who’ll get to clean that mess up? You think a bunch of selfish Europeans in BMWs will show up? LOL!”Could you possibly be any more ignorant? Unfortunately it’s people like you that give the US a bad reputation the world over that isn’t deserved. And to the people like “Mirra” that blindly criticise everyone from the US, you’re just as ignorant. Why do the most ignorant people in the world always feel the need to shout the loudest?This is hackaday! That kind of talk doesn’t belong here. Keep it civilised.",

You are aware that there are many many small countries in Europe, and that the majority are fairly “clean and green”, especially in comparison with the US in general. Emissions per capita are massively lower, toxic waste disposal is fully regulated, so much so that in many countries the output from a basic domestic water turbine is classed as industrial waste and needs analysing to ensure it’s clean! Asia is a bit of a problem, I’ll admit.I’m just amazed that anyone in the US seeks to defend their position, maybe it’s a mutual lack of understanding of each other’s country.@Mirrah – good use of subtle racism.",

It is a multi-national corporation that has based it’s headquarters in the U.K. It has put shares on several stock exchanges, and those shares do not represent anything more than the value of the investment divided by the number of shares that are issued. The corporation is so large that it has corporations, those corporations are the ones being represented in the stock exchanges, NYSE, London Stock Exchange, and the Tokyo Stock Exchanges being the three largest, and there is a BP in all three of them.

We look at a lot of projects that have microcontrollers in them. That’s because microcontrollers do cool stuff, but there are still plenty of tricks you can pull off with analog circuits.
[Osgeld’s] latest project explores this realm
, controlling the discharge of capacitors through an LED. His setup uses just nine components and, if you’ve been collecting broken electronics from your friends and neighbors like a good hacker, you can scavenge all of these parts. Try it, you’ll like it!

"content": "The problem, Reizake, is that it’s not reverse-biased, it’s just upside-down. An NPN transistor is intrinsically a symmetric device, even if the doping is highly asymmetric. Putting the “collector” down makes it behave like the emitter, while the “emitter” behaves like the collector.There’s some problems with that, though. Due to the highly asymmetric doping, the hFE is going to be a lot smaller in reverse-active mode. For a 2222, it’ll be something like 300 in forward mode, and usually 3 or so in reverse-active. The other problem is that you have to hold the emitter reverse-biased to make this happen. This is fine with a 5V supply, but if you raise it above 7V or so, the transistor will enter EBJ breakdown – and unlike the CBJ, if you break down the EBJ, you start to damage the transistor, lowering its beta over time.T2 is held biased in the reverse-active mode by R3, either pulling from the rail when the switch is closed or from the capacitor through R1 when it is open. T2 will then pull reverse-beta times the current in its base from its emitter. If you flip T2 around, the beta becomes a lot higher, and it’ll pull too hard to allow C1 to charge at all.",

Floating Globe, Hacked To Rotate

[Alexy Sha] has done this fantastic hack, where he
modified a magnetic floating globe to be motorized and spin on a tilted axis
. The original globe was simply levitating via a magnet mounted inside. Though you could spin it by hand, it wasn’t motorized, and actually floated completely vertically instead of being tilted.
[Alexy] wanted to take this idea further and make it automatically spin on a rotated axes. He built a rotation assembly that was basically a motor, hung off-center, attached at the center of the globe. He had to power it via a coil hidden in the base unit, so that it could remain light enough to float. He did a fantastic job and the final product seems like it is the true way it should have been sold.
Check out a video of it in action after the break. We actually like the spinning ring, when he’s testing it, just as much as the final spinning globe.

No matter how long you look at the globe, it will not spin in the opposite way to the motor (although it WILL spin).The reason that the globe wont spin in the opposite way is indeed due to the magnets and the control system. For the globe to spin in the opposite direction, there would need to be a vertical component to the globe spin, as the motor spin has a vertical component. It cannot spin vertically, because when it lifts a little bit, the system will detect this and reduce the field strength, causing the magnetic field to weaken until gravity counteracts the force from the motor rotation. If the system was in a low gravity environment, the whole contraption would actually start to spin vertically (albeit very very slowly). The globe will, however, slowly spin in the horizontal plane.This may be what beardysam meant, but if so he did not explain very well.",

This peculiar setup allows [Ben Krasnow] to
control an alternating current device using one pin on a microcontroller
. He’s experimenting with a power drill and has relocated the trigger circuitry that makes it spin. On that board he found a variable resistor combined with a capacitor which control a triac, actuating the speed of a drill. [Ben’s] solution works great and isolates the drill from the control circuitry. He replace the variable resistor with a cadmium sulfide photoresistor (basically a variable resistor whose resistance depends on the intensity of light). Pulse-width modulation is used to adjust the brightness of an LED shining on that photoresistor and thereby affect the speed of the drill. This is such as simple alteration to the drill we’d call it MacGyver-esque.
See a demonstration after the break.

"content": "Cudos to Ben Krasnow. This is a genius and timeless idea of yours! Congratulations. I realize, that this blog is 10 yrs old, but I’m looking into doing a similar thing for a cheap cordless drill, which also have linear potentiometers on the trigger switch circuit/PCB.(A) How did you initially figure out what type of component to use, and what range to pick from?(B) Did you open up the trigger switch and measure with a DMM the Ohm-range of the pads of the linear potentiometer in-circuit?(C) Did you measure the V across the linear pot in-circuit under load to estimate min/max V-range?(D) Did you insert an Amp-meter inline and measure the linear pot’s current draw under load to estimate Wattage for the replacement component?(E) If that’d be the appropriate way to correctly size the replacement component, how did you arrive at the conclusion that it should be a CdS photoresistor?I hope you’re still on this blog after so many years. I know some electronics, but for sure ain’t the pro you are :-)I’d be thrilled if you could guide me in the right direction.Best Regards,PQReply",

[imsolidstate] built his own pressure sensitive mat. It utilizes two discs of copper clad board with a piece of foam in between for each of 64 sensors. As the foam gets compressed, the capacitance between the two pieces of copper changes, a measurement that is fairly easy to make with an analog to digital converter. The mat is being used to measure how well a horse saddle fits the animal. Data is read in through a serial port and then mapped using Excel. This prototype proves that the concept works but [imsolidstate] mentions that there’s room to improve the sensitivity and that there could be more noise filtering incorporated into the design.

Last Friday
we looked at Wild Planet’s Spy Video TRAKR
programmable RC vehicle mostly from an end user perspective. Much of our weekend was spent dismantling and photographing the device’s internal works, and poring over code and documentation, in order to better gauge the TRAKR’s true hackability. Our prior review included some erroneous speculation…we can clarify a number of details now, and forge ahead with entirely
new
erroneous speculation!
Our plan with this teardown is to establish more concrete details of what’s hackable inside the device, what’s not, and to help nail down some of the unstated hardware specifications.
We incorrectly reported that no programming documentation or compiler is yet available. Turns out all this information was simply tucked away in a
help section of the TRAKR web site
, not on the “App BUILDR” page where we expected it.
Derp!
These resources are still in a rough state, yet proved to be a far more valuable source of information than the physical teardown. C code and PDFs aren’t very
photogenic
though, so we’ve got plenty of circuit board pr0n to start with!
Inside the Remote
There’s not as much to see or do inside the TRAKR remote, so we’ll power through that first.
The concealed rear USB port was mentioned last time, which we’ve been informed is to allow for field-upgradeable firmware. If you don’t mind being tethered to one spot, we discovered the remote can also be powered from a USB hub, or even from the TRAKR’s own USB host port.
In another nod to tinkerer-friendly design, both the remote and the TRAKR are held together with identical Phillips screws throughout, recessed but not hidden under stickers or rubber pads.
The LCD screen is one typically seen in cell phones, 15-bit color at 160×120 pixels.
The “Bot Switch PCB” has just some switches and passive components. SW1 and SW4 have dedicated purposes (home menu and power), but the functions of the others are defined by individual apps. If you’re looking for GPIO lines to hack in the remote, this might be your best bet.
The underside of the main remote PCB has some exposed pads, but there are no through-hole solder points. The pad labeled “V0_TVOUT” caught our attention, thinking it might provide a
composite video signal
, but this turned out not to be the case, or at least it’s not enabled in the present firmware. J9 looks like a
JTAG
header.
A few more test points tucked beneath the LCD.
2 megabyte SDRAM and 1 megabyte SPI flash in the remote.
We were really hoping that the joysticks might be analog internally, but no such luck…they’re simple forward/reverse switches. Even if replaced with potentiometers, without access to the firmware source there’s no way of communicating this information to the TRAKR.
The remote and TRAKR have outwardly-identical radio transceivers. They’re rather well-sealed and we’ve not dismantled them further yet, but recall hearing they’re based on a Nordic 2.4 GHz part. Wild Planet claims that with a forthcoming firmware change, they’ll be WiFi-capable. We remain hopeful but
skeptical
— it seems far more likely that the remote’s rear USB port will come into play, or in the interim perhaps one of the
SparkFun Nordic options
will prove a viable choice for PC control.
Inside the TRAKR
Removing the screws is straightforward, but fully removing the lid from the TRAKR requires several cables be detached first — and they’ve all been glued in place for reliability. We just cut through the glue with an X-acto knife and pried a bit, but maybe it can be more delicately dissolved or melted.
The right side of the main board (turned sideways here) focuses on connectivity and the CPU. The ribbon cable at left leads to the camera. The pair of two-pin headers lead to the microphone and front accessory bump switch. The purpose of the unpopulated SW1 isn’t known — it might be that early designs featured an additional rear or top switch, now vestigial. The larger headers lead to the radio module and the trim pots and recessed reset/debug switches on the bot’s undercarriage.
No need to get through that epoxy blob. Digging through configuration files for the compiler, the chip appears to be a Nuvoton
W55VA91
, featuring an ARM926EJ core running at 192 MHz, and hardware-assisted JPEG codec.
The middle section of the board is what TRAKR-hackers will become most acquainted with. JACK3, the vertical row of pads in the center, contains 8 digital GPIO lines and one analog input, with 0.1″ pin spacing. JACK4 looks like a JTAG port, with 2mm pin spacing. Below that is the connector for the USB host port, and the second (unpopulated) port at the right can be used as a 5V source. It’s a real shame that power and ground were overlooked on JACK3 despite its proximity to those traces. With the addition of power traces and a row header soldered in place, this would have made a nice standardized riser for small add-ons, much like the ecosystem of Arduino “
shields
” that has taken off.
Left side of the board is devoted mainly to power and motor control. The red/black wires at left lead to the battery compartment. Connector above that is for the speaker. The two 3-pin connectors at the bottom lead to the left and right motors, with the H-bridge driver circuit above that.
By the way — if you dismantle your TRAKR, when it comes time to put it back together, there are four screw holes that aren’t actually used despite their labeling on the silkscreen layer. You can see three of these in the photo above, and the fourth in a prior photo near the camera connector. Forcing screws in could damage one of the motor cables underneath!
Little to see on the underside. Another inactive V0_TVOUT pad taunts us! This side is dominated mostly by the SD card socket, and…
…ample 8 megabyte SDRAM, 2 megabyte flash. Together with the SD slot, USB and ARM9 CPU, we’re anticipating
ucLinux
and
DOOM
to be ported in 3…2…1…
The USB host port is on a small daughter board, and each of the motors has some local driver circuitry as well.
Each motor is driven through a reduction
gearbox
. They operate quietly with only a slight amount of slop. As with the radio, we’ve not further dismantled these yet.
Though not powered, the front wheels aren’t as boring as we first thought. This rack and spring mechanism keeps a constant tension on the rubber tread belts, allowing them to flex and maintain traction as the TRAKR drives over various terrain.
The partly-disassembled camera pivot mechanism. Two small rubber pads provide just enough friction to hold the camera in its set position, yet still allow it to pivot easily. If attempting to add
servo control
to the camera, removing those pads will likely help.
The camera is connected to the main PCB with a 24-conductor flex cable, 0.5mm pitch and about 6 inches long. Mounting the camera in a higher position might best be done by replacing the entire cable with a longer one, but we’ve yet to locate a suitable match from a source such as DigiKey.
Extracting the camera PCB from its housing, we were greeted with a low-hanging hack opportunity: the board was designed to accommodate multiple LEDs, but in practice shipped with just one large one in place.
Boosting the light output
should be a very simple matter of adding the missing resistors and LEDs, though you’ll need to drill holes through the case or run wires to mount the LEDs externally.
We’re not 100% certain of the camera sensor yet. From PR materials at Maker Faire, we know it’s from OmniVision, but don’t know the exact model. Based on size and specifications, the OV7670 looks like a possibility, in which case it
should
be capable of full VGA resolution, not just the QVGA output we’ve seen.
The “accessory port” is just a passive attachment point to clip things on; it resembles a headphone jack, but isn’t. There is a pushbutton switch behind it, maybe an interactive cat-poking stick is planned.
The artist’s signature.
Reassembly was straightforward. Cable connectors are keyed for orientation, and for those that aren’t a unique size, the correct positions can be inferred from cable length. And there was no mysterious “extra screw” at the end — everything went together easily and worked on the first try.

mounting external microcontrollers
or other devices to the rear transport deck. Adding a microcontroller isn’t an entirely ridiculous prospect — even though the TRAKR’s CPU has far more “oomph,” it remains to be seen if the GPIO lines are suited to tasks such as accurate
PWM
for servo control. Delegating such tasks may prove helpful, or even necessary. The usable area of the transport deck is a bit over five inches wide and three inches deep, and a couple of rubber bands or some foam tape will hold most boards securely. With the deck removed, the recessed notch above the battery bay is such a perfect size for certain things, it’s almost uncanny. Did [Dave] plan this?
Arduino, natch. Small devices like this can be powered from the TRAKR’s USB host port, but without an
FTDI
driver on the host side this connection can’t be used for serial communication.
Half-size and quarter-size breadboards fit exceedingly well, almost snapping into place. But anything placed back here though is going to block access to the SD and USB ports.
More Hack Ideas
Having explored the hardware inside and out, we’re already ruminating on the possibilities…
The TRAKR has a big infrared LED on the front (with two more easily added). The firmware for
TV-B-Gone
is open source. Enough said.
With the transport deck removed, the rear wheels of the TRAKR protrude slightly behind the body. With the addition of a gyro sensor, will it be possible to get the TRAKR to stand upright and scoot around
Segway
-style? The remote’s joysticks are non-proportional, but software control of the motors allows for very fine speed adjustment. It’s
been done with LEGO NXT
, so we think the practicality of this idea will come down to the responsiveness of the TRAKR’s motors. (Yes, we
know
it’s just propped up against the back wall there.
Shhh!
)
The wide stance of the TRAKR has us contemplating a
Chalkbot
or
txtBomber
printer attachment: the eight GPIO lines could be used to control a
row of solenoids
attached to paint markers or chalk hoppers. We didn’t have the parts on hand to build a physical printer right away, but we did have some
addressable LED bars
from another project, so a proof-of-concept was possible using
long-exposure photography
. And
it works!
We’ll elaborate on this hack in a subsequent article as we get our hands dirty…
very
dirty…with the TRAKR C compiler.

There is no public datasheet nor a .h file with the definition of all peripheral registers.The SDK contains some source files in the Internals folder, but most of them just make calls to functions that begin with JAPI_ and seem to be in the JAPI.a binary blob.So running alternative firmwares (say uClinux for example) or adding support for things such as video out or GPU that were not intended to be used might be rather difficult.",

Use A Big Magnet To Set The Time

This bulky package is
a Nixie tube wristwatch
. We still like
[Woz’s
] watch
better but this one has a few nice tricks of its own. Notably, there aren’t any buttons to set the time. Instead, a large magnet is used to actuate a magnetic switch inside the body. Speaking of enclosures, the case is aluminum and the face plate is polycarbonate but looks like it’s been vacuum formed. Check out the clip after the break.

The larger battery is for the smps to provide 170 V for the tubes. The lithium cell is for the 3 V logic circuit, and it lasts longer than the “anode battery”.The watch weights 60 grams.

[Manuel]
built his own thermal printer
based around an Arduino. We’re a bit confused about the parts, his webpage specifies an EFA-1019HW2 print head but the bill of materials on
his
github
shows EPT-1019W2. We can’t find a source for either product number, but we did find similar thermal line printers for as low as $32.00. The controller boards on the other hand look to be around $150 so building your own is a definite win. [Manuel’s] version can print 96 points and has a font set that prints 32 characters per line. Check out the video after the break and let us know if the noise of the print head is a deal killer for you.

[Jackzylkin] has posted an instructible showing, in detail, the process of creating a
USB typewriter
. He takes us through the process of disassembling the typewriter, mounting all the sensors where the little hammers strike, and wiring it all up to a custom board to interface with the computer via USB. While he is selling the board, the schematics are available if you want to build your own. We think the clickety-clack of a real typewriter could be very satisfying to the touch, though it might drive your co workers insane. The younger ones might also quiz you as to what that archaic machine is. We’ve actually seen
this done before
, way back in 2005.

Evil Mad Scientist posted a story about
what went into developing the Bulbdial clock
. We think
the Bulbdial
is one of the best pieces of kit out there for many reasons; using colored shadows for each hand is a brilliant idea, the design is clever and uses a low parts count, and the concentric rings that make it work also add to the aesthetic. But after seeing the
original wood prototype
it had crossed our minds that developing those circular PCBs isn’t the easiest thing to pull off. To save on board cost, the first run didn’t have the center routed out, but rather used almost-touching holes drilled during manufacture and finished by hand during assembly. They also go on to discuss the use of
Charlieplexing
to reduce part count and the search for a suitable diffuser for the clock face.

[Whoopjohn] decided to
build a driver board for a display
he pulled from a pinball machine. You’ve probably seen these used to scroll both score and messages using a total of sixteen 15-segment digits. We’d love to get our hands on one, and you might too but where? [Whoopjohn] notes that these were usually installed two-per machine and the driver boards were run close to their maximum ratings. That means that somewhere there’s a collection of broken machines with working displays. If you do plan to make this happen, you should be able to figure out the circuit based on
this commented board layout (pdf)

Most digits have a decimal point and comma, so that makes 16 segments I guess, but in a 7 segment display you don’t count these as segments. The right hand last pair of digits have no commas.There are some 7 digit version of these displays, which might make a more modest starting point.This clock is still waiting for some crazy pinball-style scrolling routines to be added. It still works well, is flicker-free.The MAX1771 chip I used for the 12v to 180v converter is very very picky about layout, especially in the feedback loop. It can pick up noise and fail to regulate, although here my present configuration is stable. I have issues in another clock using this device. The current sensing resistors shown are too high. Should be a total of .05 ohm, not 0.5.The display PCBs that use these arrays have UDN driver ICs that are unobtainium. Most were working at their absolute limit and these chips tended to fry easily. These used a +90v 0v and -90v configuration.I used Ov and 180v and a pull-mid to around 100v, based on the standard Bally display circuitry they used on their earlier 6 and 7 digit displays. These you can easily find on the web. There are two transistors for the anode drivers and one per cathode driver. You can’t see these in the picture because they are surface mounted on the other side, as are some of the necessary resistors. So you won’t work it out from the picture but they are on my annotated PCB.No I don’t have a schematic. schematics are for wimps. I vaguely work out a strategy, go straight to PBC design. I use Osmond PCB on a Mac. I etch a board and hope for the best. Works for me. Usually.Whoop John",
