Introduction: The Enigma Switch Box
I was fortunate enough to obtain a very large collection of switches, buttons, knobs, and potentiometers from nearby closing RadioShacks. I made this switch board into a puzzle by attaching a battery and wiring the switches so that only a certain combination would turn on the lights. It is a very simple project and would be a great "busy board" for young children.
Step 1: Assembly
After the video, I made the puzzle much more difficult to solve. I made use of the 11 position selector switch and the potentiometer. The light will only turn on if the selector switch is pointed in a certain direction, the potentiometer is turned all the way to the right and a specific sequence of toggle switches are triggered. You can make this surprisingly difficult. My current wiring allows for 45056 combinations and only one of them triggers the lights. Start off by deciding where to put your battery and then cutting holes in your enclosure for the switches and buttons. Solder everything up and get as creative as you want. That's it!
