Build Your Own Electric Etch-A-Sketch 104
mhaisley writes "Ok, case mods are cool, monitor mods are nifty... but an Electric Etch-a-Sketch beats either. Students at Cornell University built an electronically controlled etch-a-sketch, controllable by a PC mouse. This was part of a group of class final projects featured by their instructor."

It's quite easy. You simply rotate the knobs either clockwise or counter-clockwise depending on whether the sine wave sample is above the x axis or below it and at a speed indicated by the value of the y axis. Obviously, the x axis represents time.
The only tricky part is remembering that the left and right knobs aren't ever at the same point in the sine wave so you have to remember that your left hand and right hand might be moving in different directions and at different speeds. At first I founnd that it helped to use a precalculated lookup table but now I can just do the trig calculations on the fly.
Hope that helps!
