Virtual Circuits
Optoisolator 1 proof of concept (2 gates only, arranged for visibility)

pattern logic version 1 (input: 2 state switches; output: motor)

pattern logic version 2 (version 1, with indicators on input end and color changing output light)

pattern logic version 3 (version 2, but oscillators added and inputs reduced to 3 to make room)* this one is actually broken, have to remove lower or gate from blanking logic and re wire to make it work

Pattern logic version 4 (Version 3, but oscillators calibrated to make sequential pulses)
