I redesigned the schematic, but I'm not sure if the opto is hooked up properly, that is just a general opto, I will be using a better one. Also if I put a series red led(I have multiple sizes) wat voltage drop should I expect across it. http://www.angelfire.com/mech/homerov/rocket/schem.jpg -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
