Hi, I'm trying to set up a circuit with a tri-colour LED, which would change colour depending on the temperature. I used to have plans for one, but when I built it, it didn't work very well (it was chronic at low temperatures). Could anyone possibly whip up a PCB layout? (I'm in the UK, and get most stuff from Maplin). I'd probably want to connect it to a battery, rather than directly to a PSU first (I remember reading somewhere that someone had rigged up a molex connector to a battery). Cheers.
