Wiichuck: the Quickest Way to Hack Your Nunchuck Controller

 |  |  |  |  |  |  |  |  |  August 18, 2009

This tiny little 1cm x 3cm circuit board may not look like much, but the WiiChuck is the easiest way ever to unlock the world of Wii Nunchuck hacking.


Just plug the WiiChuck into to bottom of your Wii Nunchuck controller, and you’ll have access to all of the wonderful data the controller can generate. No more cable cutting! The teensy adapter board provides quick access to the Nunchuck’s interface, letting you use data sent from the controller’s 2-axis joystick, two buttons and a 3 axis ±2g accelerometer.


And if you’re into Arduino build projects, you can head on over to TodBot’s site and grab some open source libraries to get you started with reading the data from the Nunchuck and using it in your own programs. The best part is that each WiiChuck costs just $2.95 (USD). Head on over to SparkFun and grab one if you have any interest in hacking your Nunchuck.
