Originally designed for Maker Faire workshops by Joe Grand, the “Build Your Own Electronic Game Kit” is a custom-created kit intended to introduce folks to the world of electronics and soldering. When successfully assembled, the kit becomes a version of the popular memory game, Simon, with a few optional twists, including no LEDs, no sound, reverse order, and fast play. The kit includes all the necessary components, including a pre-programmed microprocessor, custom circuit board, and battery. The only other materials you will need are a soldering iron, solder, and wire snips. Assembly instructions, parts list, and game instructions are all printed on the back of the circuit board. A schematic of the design is available here (PDF). The kit is available for just $39.95 and in stock in the MAKE store – Link.
