Hi all, I've been fooling around with electricity for over 30 years now, and connecting that final wire to batteries, especially high voltage/current ones, still makes me cringe. I'd swear I'm on the verge of a heart attack when that sneaky blue spark jumps out with a loud crack to unceremoniously tell you that you've done something wrong. regards Tony -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!
