Apple Adjustable Keyboard USB Hack

usbkeyboard

When [Tom] got tired of the large size of his Microsoft Comfort Curve 2000 keyboard, he decided to hack a recently acquired Apple Adjustable Keyboard for use with Windows. After removing the ancient ADB based control board from the Apple keyboard, he was able to map the keys and transplant the Microsoft keyboard’s USB control board into the Apple keyboard. After soldering the control board into the keyboard with old IDE cables, all that was left was to add some diodes to prevent ghost key presses, and the keyboard hack was complete. [Tom] offers a spreadsheet of the results of his key mapping on his site, and while you’re there be sure to check out his other projects, like his DIY Proton Pack that he made for Halloween last year.

DIY AVR USB RGB LED Notifier

Giving us a chance to break out the TLAs, [Blair] sent in his latest hack where he embedded an RGB LED into his EeePC to display twitter, pidgin, and email notifications. It is based around the ATtiny45, and requires very few additional parts. He based the project on a foundation of work laid by [Dennis Schulze] on notifications and the work of [Dave Hillier] that used V-USB, a library for implementing USB on AVRs. The entire circuit was done freehand and crammed inside the netbook. He says that it is a lot easier to see notifications, even when the laptop is shut.

World Smallest TV-B-Gone

The TV-B-Gone has proven to be a dangerous and versatile gadget. At Interactive Matter, they created an even smaller version with more sneaking potential. Called the µTVBG, it packs an entire TV-B-Gone in a 1.4 x 2.5 cm footprint and even has room for a programming header. He found some high-powered surface-mount IR LEDs that would match the original TV-B-Gone’s power. To drive the board, they used a CR1220 button battery on the bottom of the board. The whole thing is smaller than your thumb and should be easier to hide next time you wreak havoc.

OTTO, Beat Slicing Interface

otto

Create Digital Music has a great post on [Luca De Rosso]’s OTTO. Built as part of his masters’ thesis, it’s a unique tangible music interface. You load a sample into the software which displays it on the instrument surface. The user can then manipulate the sample using various hardware inputs while watching the LED representation. The device uses just one Arduino for the display and inputs. It works with Max/MSP and is designed to give the performer only the information they truly need. You can find more pictures of the device on Flickr and a picture of the guts on CDM. Embedded below is the ‘Getting Started’ video that shows it in use.

D-touch Tangible Drum Interface

yes, drums are tangible. We know. What this is, however, is a tangible interface that is a drum machine. The software is freely available for download, after registration. For hardware, all you need is a webcam, a computer, and a way to print out the pieces. D-Touch is cross platform which is very nice. Please note that the software will not run until you activate it by putting in your user account from their site. If you like this project, you might also get a kick out of the Go Sequencer.

Wii Balance Board

[Matt Cutts], head developer for google’s anti spam team, describes how to attach a Wii balance board to a linux computer. He even shows how to make a GUI to show the input. The entire project is done in about 200 lines of python.The process assumes that you can already make a bluetooth connection to a WiiMote, but if you can’t, he’s got instructions for that too.

AVR RFID Tag

[pc486] sent in his hack that uses an ATtiny85 to act like an EM4102, a chip used for RFID tags. Minimally, all that is needed is the AVR and a coil, but he recommends some filtering capacitors. Depending on the size of the coil, different frequencies and ranges can be achieved. This project actually includes several hacks, such as using the coil for not only power, but a clock signal. The coil is actually able to power the chip without being connected to the power pins due to clamping diodes on the connected pins. The firmware is short but available on subversion.
