See: http://www.botkin.org/dale/yardlites/yardlites.html I use two MOSFETs to switch the low-voltage AC side, derive the PIC DC power from the AC as well. Works like a charm. I'm currently looking at adding two more MOSFETs in parallel to reduce the heat, but then I'm switching over 100W. I've had this in use for about a month or so now, works perfectly. Big tip of the hat to Dave Dilatush for the idea. Dale -- http://www.piclist.com hint: The PICList is archived three different ways. See http://www.piclist.com/#archives for details.
