Earlier this week, fellow Hack a Day-er [Mike Nathan] reviewed Adafruit’s new iPhone/iPad app Circuit Playground. The comments on [Mike]’s review turned to suggesting ElectroDroid as an alternative to Circuit Playground. Surprisingly, Hack a Day authors actually pay attention to the comments, so I’ve decided to throw my hat into the ring and offer up my review of ElectroDroid. For purposes of full disclosure, I have to add that I paid the $2.59 donation for a copy of ElectroDroid without ads, and have had no contact with the developers.

This video game controller is a factory fresh VW. Much like the racing simulator from earlier in the week, the video game data is being displayed on the instrument panel. This takes us to a much higher level now because control for the game is taken from the car’s CANbus using and ODB-II connector. If you don’t speak in automotive jargon, that means that the sensor readings from the steering wheel, shifter, and pedals are being picked up and exported as joystick commands to the PC running the driving game. The only place the experience uses a substitute for the real thing is the sound, which is being played through speakers instead of emanating from under the hood. Looks like you just need to add a projector and screen to your garage in order to turn it into the hottest new gaming device.
A few weeks ago we wrote about our Bus Pirate universal serial interface tool. We used the recent holiday to add some new features, like a JTAG programmer, macros, frequency measurement, and more. A major code reorganization makes everything easier to read and update.
Check out the a demonstration of the new features below. We’re compiling a roadmap and wish list, so share your ideas in the comments. You can also see how we used the Bus Pirate to read a smart card and test-drive an I2C crystal oscillator.

OBD-II became the mandatory I/O diagnostic port on cars starting around 1996 in the US. Considering that the interface consists of a couple of I/O lines, serial/usb adapters have been ridiculously expensive for quite a while – especially newer USB versions. [Renan] sent in this PIC18F2450 OBD-II interface. The designer says he can provide boards for just over $6 and programmed PICs if there’s interest. The chip is a few dollars, and everything else is pretty cheap too. Need to work on your car? This thing will cost $15 or so. I think I just might have to burn out a board on my mill later.
[Dancerman] sent us a couple pdfs covering the Navy’s research on railguns which might show up on new platforms like the DD(X): first is NRAC’s Electromagnetic Gun Technology Assessment, second is slides from the Annual Gun & Ammo Symposium which covers the problems encountered when scaling a system up for ship use.
I was pretty tired of railguns by the time someone sent in the obligatory Powelabs link. So, I read about Sam’s Subaru 2.5RS engine swap and watched the sandboarding videos instead.
[george] knows that these a pretty common, but his laptop picture frame looks pretty good. He added WiFi and Bluetooth adapters to the empty battery bay so that he could have remote access and control the frame with his phone.
[Douglas J. Hickok] used a solar powered yard light to illuminate his Jack-O-Lantern. It ends up looking like a hat.
[tio.chorizo] doesn’t want to pay for the Nano lanyard headphones so he modified his stock ones. He made a large loop and then used heat shrink tubing to hold it in place. Here is a Coral Cache of his photos.
[seth fogie] pointed us to airscanner’s page of iTunes DOS/Spoofing attacks with flash demos.

This Engadget post has links to commercial clothing that has integrated controls and power. Now someone just needs to do it for cheap.
Cool Tools featured a blackbox for your car. It plugs into your OBD-II port and records the signals coming from your ECU. If you are in an accident it will have the information from right before the impact.
Cinematical highlighted the documentary Project Grizzly. It’s the story of Troy Hurtubise who built a bear proof suit and is now claiming he can see through walls/cure cancer.
