Gameshow buzzer: prototype

The prototyped gameshow buzzer system: good, old fashioned relay logic. The bottom set of relays are the heart of the system. The first person to buzz in causes their relay to latch, cutting power to the other player's buzzers. The upper set of relays will be in each of the buzzer boxes and switch on the 'I buzzed in first' lights.

 

The 'game show' for which this was built never happened, so it was never completed. Someday, maybe.
