=A0Friend has me thinking about this...if you take 110VAC and half wave rec= tify it, your going to end up with around 150VDC peak, so with the correct = resistor(7k-8K) it should drive a standard LED OK?=A0 Guess I've never real= ly thought about driving it directly from AC.=A0 Yes..I know, its non-isola= ted so its at the AC potential and a shock hazard.=A0 Without a capacitor, = you will see flicker on it as well of course. --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
