DS brut is an open source hardware prototyping platform for the Nintendo DS
By connecting the Nintendo DS to the outer world with UART, GPIO, PWM, ADC, I²C, etc, the game console can be easily hooked up to a variety of sensors (e.g. GPS receivers) and can itself control all different kinds of actuators, servo motors and others.
Together with the cartridges a library for easily interfacing the outer world from within your homebrew software program is also released - similar to the way things work with the Arduino. As it is LGPL licensed, you are free to modify it to your specific needs. You also have full access to the embedded microcontroller's firmware, which is also provided as sourcecode and can be easily compiled with free and available tools - meaning that you can modify every aspect of the device if you want to.
