Cheap Electronic Whiteboard
Via ExtremeTech
Johnny Lee, a student at Carnegie Mellon University, has devised a way to turn a cheap WiiMote into an electronic whiteboard using a common video projector and some infrared light pens. The best part is that he is releasing the software to do this free of charge.
An interesting thing that I learned from this is that the WiiMote is actually the infrared sensor and the WiiBar is the emitter. In my limited experience with the Wii, I figured that it was the other way around, though it does make more sense to have it be the way it is.
