Opti-Isolator Circuit

The opti-isolator circuit. Everytime a light on the orginal simon goes on, it triggers this circuit to light up my new string of 36 lights. The original simon uses about 2.4 volts per light. I needed to run about 10 times that. I think the schematic is visible enough for you to copy if you like. :-)
