Make a cute Arduino file manager and editor. It’s also intended for hosting sketches and interact with them in an easy way using a PS2 Keyboard.
Thanks to Juan who developed this project called blocporc!
Watchduino is an open source Arduino Smart Watch that combines inexpensive electronic parts with complex Arduino (C++) code. It’s fully hackable from hardware to software. You can build your own one, it’s useful and reprogrammable.
Try this open hardware and open source hack to turn on/off lights with just a touch.
