I have designed a transformer switching circuit using RatShack triacs,
optocoupler (part MOC???? - I forget, but the part is at the shack, designed
for switching triacs), driver transistors for the LED in the optoisolator,
and everything driven by a Basic Stamp controller from Parallax. The nice
thing about the stamp (which is a PIC controller) is the ease at which one
can program the part - just write some simple BASIC code, hook up to
a PC, and download into the stamps EEPROM. There is also built-in
serial communications on the stamp, so the controls can originate
from a PC. The programming software is free, and the stamps costs
around $21.00
