WiiCamera DIY Kit

WiiCamera DIY Kit


*Shown Assembled
*This kit no longer includes the NunChuck breakout board


Put simply, the WiiCamera is a tiny IR camera harvested from a Nintendo WiiMote. In its native habitat, this camera can "see" the 2 IR lights inside the Sensor Bar placed near your TV. Add a little trigonometry, and the Wii controller knows exactly where it is in relation to the screen. In the robot world, this can translate into the ability to track and follow an IR light, travel to a "homing beacon", find and extinguish candles and much more. Add a near-IR laser and an accurate, inexpensive laser-radar system can be built. 

This kit includes everything you need to build your own WiiCam sensor (minus the WiiCam itself). Broken WiiCams are widely available for a few bucks on Ebay. Once assembled, 5v, 3.3v, gnd and connection to the i2c lines of your microcontroller is all you need. Mounting holes have been provided that can mount directly to a micro servo. There are even a few libraries available for the Arduino (see left sidebar). 

So how does it work?
The camera can "see" up to 4 points of IR (or near IR) light. For each point, the camera outputs an X/Y position, size and brightness. The library does all the work for you and you are left with nice, simple numbers to work with in your code.

Included in the kit:
  • WiiCamera breakout board
  • All component parts needed for assembly

Required to complete the kit:

  • Soldering iron, solder and flux
  • Broken (or working) name-brand WiiMote (available on Ebay)
  • Small flat screwdriver
See video below for assembly instructions.
