Years ago I had a simple schematic that showed how to create a double relay using electric magnetic switches. This was real, real basic. You know with nails and batterys, simple. The basic operation was if one of the circuits was closed (or was opened), it would signal the other side to close. I can't remember how to make this to mess around with.
My goal is another project that I am working on for my daughters Karate class. Where they have to kick a target but not drop their leg before or after the kick is delivered. I've got the major parts figured out and I could use the game buzzer circuit tip, but I still want to remember how to do it with nails and wires if possible.
Anyone out there know how to do this?
