About 3 months ago, i was working on a light touch sensor for my LCD that i reverse engineered (for my coffee maker machine :D ). But it failed to operate. The reason was that there had to be many IR receiver LEDs on one side. Today, i was rather amazed when i saw this video from Spritetm. Instead of using IR LEDs as receivers, he used a line-CCD from a scanner. And then i remembered that somewhere, some-when, i had myself a b/w (very) old scanner... Very nice job and excellent solution Spritetm!
