After much searching of the board I didn't find this basic circuit anywhere, could be used for several different jobs.
I have a question, does anybody know of a way to delay off the relay by maybe 30 seconds without getting into a 555 timer circuit? In short I would like the relay to stay energized after the opamp pin 6 signals it to off.
Maybe a cap and transistor arrangement, the circuit draws 38 ma when the led and relay are on so maybe a 555 is the only option, not sure.
Thanks
fv(king huge pic and a dumb ?? not worth my time to fix imho.
