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.

  1. @doublet um but then how would be see the realtime interface between nunchuck and screen? If there is nothing but the screen then yes, screen capture should be a must, but if you are interacting with the screen no. We need to see how the system interacts.

    My nitpick time, tripod please?

    Chill out man. I’m just saying filming your own screen isn’t the best way and isn’t very clear. I don’t say his project sucks (it’s awesome!). Next time turn your caps-lock off and act like a big boy.

  3. @rousselmanu: RE: Camstudio

    “with the unique Video Annotation feature you can even personalise your videos by including a webcam movie of yourself “picture-in-picture” over your desktop.” That would allow a sharp, clear screen image along with an inset video of the controller itself in action.

    1. I know the question is 4 years old (!), but I missed it and as it is of primary importance, I will give an answer now:
      code: no (too bad!)
      cook: yes
      solder: no
      film a computer screen: yes!
      can be used as a shaky camera tripod: yes!
      My sister is awesome

  4. First of all, nice hack rousselmanu

    Secondly, to all of you suggesting CamStudio,
    from the excellent video, it looks like rousselmanu is using Linux/GNU, I can’t seem to find anything about Linux/GNU at
    Is there a Linux/GNU version of CamStudio, or does it work in Wine?

    Ps. sorry for my bad English
