ChessLR. Me and Rob got together to talk about the electronic chess board today. He showed a proof of concept using reed switches, a magnet, and an LED. Man that was cool. The reed switch is amazingly sensitive to the magnetic field of a magnet. I was able to hold the magnet about 3cm away and the reed switch was still able to sense it. I did find that there was a bit of a dead zone in the middle of the switch, which could prove problematic. But no problems reading it through a piece of wood.
