Here’s a radical idea: Put down that PSP for a while. Give your tired fingers a break from its complex configurations of buttons and action controls, and try a whole different kind of game machine, one that uses just a single button and can be built and modified at home. At the core of this simple yet elegant retro game platform is a device called a ScreenKey, a small LCD screen built on top of a pushbutton. Couple it with a tiny programmable microcontroller, and you have a complete portable DIY “GameKey” system.

Do you need a microcontroller for a project (maybe, ahem, our Mood Cube project?) but case space is at a premium? Well, fret no more. The Really Bare Bones Board (RBBB) Freeduino PCB is the perfect fit.
