I created the following schematic in 2002 and built it into a working game show style
lock-out buzzer system. The patrol switch boxes and display board were built by
Frank Davol. Due to the nature of the game, high quality debounced switches
should be used in the patrol switch boxes.
Old computer mice could also be used.

the pdf file of it.

I also created a spreadsheet for scoring The Wood Badge Game Show and The
Game of Life. Click
