I've got a circuit diag now. But i want 2 modify it a bit.I found an Ic , a display driver whose only purpose is just to signal when voltage level changes polarity. I thought of replacing it with something else, maybe an opamp,or voltage comparator. What d'u think?
Also, there's another ic (7402 I think) that has a 9v line going in, and a 5v line coming out. It looks like a power ic of some sort, but I can't identify it. Anybody have an idea what it is?
