Bluetooth-enabled Wii nunchuck

The wireless controller for the Nintendo Wii has been used in many a hack due to its simple to use Bluetooth interface. The nunchuck portion of the controller however, has always required a physical tether to the wireless controller, or an aftermarket wireless dongle. [Rousselmanu] is looking to change that with his Bluetooth-enabled wireless Wii nunchuck. He is able to retrieve a slew of data from the nunchuck, including information from all of the accelerometers, buttons, as well as the joystick. The data is read into a PIC MCU and relayed via serial to a Bluetooth module he purchased online.
The Bluetooth module looks fairly easy to interface in Linux, and [Rousselmanu] has a video showing off how well the nunchuck can be used to interact with 3D models. He admits that the controller is a bit ugly at the moment as all the components don’t quite fit so well, but future revisions will surely remedy that.
