CYLON eye 2

Although a bit more comples than CYLON eye 1, this circuit is a more accurate recreation of the "walking light" CYLON red-eye.  It uses the same shift register circuit but also employs a Set-Reset flip flop to bounce the light from one direction to the other. ( the inputs S1 and S0 are the direction select controls for the 74194 )

To run this circuit, turn on the Vulcan and turn on and off switch S8 to load the single bit into the shift register and watch the fun.
