If you are into music and like to hack your Wii have a look at this Wiimote AirDeck Virtual Theremin project. It allows you to get your DJ on and bust out some tunes.
“Here is some video I shot shortly after my project presentation which demonstrates the AirDeck virtual theremin application I designed and explains some of the features. It uses the Wii remote as an input mechanism by tracking motion with Infrared LEDs. The AirDeck is written in Java with the WiiUseJ API for handling Wii remote events and the JSyn API for internal synthesis. It can control MIDI out as well as offering a simple DJ scratch interface for real-time manipulation of sound samples similar to a DJ scratching with vinyl records.”
Matt Cutts has developed a python program that allows a Linux computer to connect to a Wii Balance Board via blue tooth and display the results graphically in real time.
“Each sensor returns 2 bytes of data and also has six bytes of calibration data. Think of it as a 16 bit number and three calibration numbers, that are also 16 bits apiece. The three calibration numbers correspond to the sensor reading for 0 kg, 17 kg, and 34 kg (those numbers should look familiar if you look at the previous paragraph). So if sensor #1 gives a value of 5725 and the 34 kg number is also 5725, then that sensor is reporting exactly 34 kg of weight on it.”
