Switching channels
I would imagine you could hook up a simple 7400 series binary counter IC to do the trick. Of course depending on the encoding of the rotary switch it may not switch in A->B->C->D order, but who cares? If you do care, you can hack the binary counter with some XOR gates. Have that driven by a 555 timer IC with a pot to adjust your timing and a switch to stop the timer and you're set. Adding sync detection in place of a manual stop would really be cool.
Next week I'll order up some X10 gear and let you guys know what progress is made. If anyone else is interested in a project like this, drop me a line in here.
