Spark Fun Electronics has a pretty neat “Simon” like game (source and schematic included) all for $24.95 – “Looking for an application for the button pads, we ultimately settled on re-creating this classic. It blinks. It makes a lot of noise. And it’s guaranteed to suck you away from doing any real work.

This is a good demo board for our button pads, DC to DC step up, LEDs, battery holders, buzzer, pseudo-random number generator for game sequence, etc. The firmware is available below as well as schematics to see how we did it. Buy the board for a quick toy or re-write the code to create mega-Simon.”Link.

We also have a Simon kit in our MAKE store to check out… Originally designed for the Maker Faire by Grand Idea Studio, the Build Your Own Electronic Game Kit is a custom-created kit intended to introduce you 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 (schematic included) – Link.
