They won't work. I'm having a LOT of trouble with the MOSFET switches. All I want is a relay type thing that will consume nex= t to no power, but I can't generate the appropriate gate-source voltage like = a real SSR does with a photocell. How would I go about doing this? --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
