If > you ever take it out... I didn't take it out. Unfortunately, it's soldered in and I don't think I can unsolder it with the equipment I have here. I'm looking at rebuilding the controller from scratch. It raises new problems though. The only resistors in the output circuits are between the pic and the to-92 package with a house number (transistor base?). Given that, I would assume the LED strips have the resistors in them, but they're glued shut in a way that I can't open without causing a lot of damage. _______________________________________________ http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
