DS Bluetooth/DS Brut and DS GIG are open source platforms and easy-to-use interface systems for the Nintendo DS, intended for electronic enthusiasts, artists and game designers. They enable your NDS to communicate with sensors, servos, GPS modules, UMTS mobile phones, motors and many other actuators. You can easily implement your own applications by programming Homebrew software on your DS or you can even use the DS Bluetooth cartridge standalone.
