Hi people.
Got this circuit all working, but it runs off mains 240V AC. I would like to convert it to run of 12V DC.
It has a 0 Crossing test, to check the 240V so need to fool this into thinking its all good, to run the program in the PIC.
Any ideas? I can power up from 12V DC by supplying 12V to D1. But the self test fails.
HELP please
Will
