Roulette using relays. (x2 Speed)
I doubled the speed of the roulette, although the operation is a little suspect.
Perhaps by forcing it to a double-edge trigger specification, it fails to retain itself.
If you actually make it, ver1 is more reliable.
This is a roulette using a pseudo-random number generator circuit with Galois linear feedback shift register.
The lamp in the upper left corner of the roulette lights up when the roulette is on standby.
The rotation is started by pushing the push-switch in the center of the roulette.
The rotation speed is gradually slowed down, and the standby lamp lights up when the rotation stops.
