G'day! I've been scratching my head over this for a while, and would be very grateful for anyone's input.
I bought some 9V dual coil latching relays to experiment with a true-bypass mod. What I am attempting to do is use a latching relay to do the true bypass switching so that the battery isn't drained by the "on" current of a non-latching relay.
I am trying to dream up a conversion circuit that will change the ~5V continuous signal from each side of the pedal flip-flop into the appropriate short duration pulses to flip the relay from one latched state to the other.
This is what I mean:
So what I want to do is to build the convertor. I have a circuit based on a D-type CMOS flip flop (4013) that will convert the continuous signal at A and B to a pulse. But for some reason it fails when connected to a live pedal - the flip-flop in the pedal seems to be both on and off momentarily and that confuses the convertor.
quote:Originally posted by Dr. Bob But why even use the flip-flop in the pedal? Why not disconnect the switch, & use it to drive a Tranny-FET, into your 4013.
See... now that's why I post stuff on here. I've been so close to the problem, I couldn't see the forest for the trees - didn't even think of that. That will simplify things about 2000% !! Thank you!
A seriously technical question...
