Doing some searching, I've come up emtpy, but somewhere I've seen some notes on this. Using a standard LED, but driving it with low voltage AC (24V or 48V). Seems like one was a resistor only solution but another was a res/cap solution. So does anyone have a reference to this? Seems like it should be simple to do, but curious about the underlying concept about it. _________________________________________________________________ Help STOP SPAM with the new MSN 8 and get 2 months FREE* http://join.msn.com/?page=features/junkmail -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
