The Game-o-Tron Mini is a pint-sized but powerful handheld game console with a nostalgic look and feel.

About the size of a credit card, the mini uses a Teensy 3.2 to drive a 128×96 pixel OLED display and speaker. Inputs include 8 push buttons and an on / off switch with a rainbow color scheme reminiscent of the Nintendo 64 controller. The entire device is powered by three AAA batteries which fit snuggly into the 3D printed case alongside the other electronics. The mini is the third in a series of game controllers designed by UK-based maker David Boucher. The Game-o-Tron 3000 uses a Teensy 3.1 and a 320×240 pixels screen. While software development for the mini is still in progress, the complete software and hardware development process for the 3000 is available on Boucher’s website.

Some of Boucher’s other interesting projects include a pocket-sized EDSAC (Electronic Delay Storage Automatic Calculator) and a Teensy command line compile program which allows you to run Teensy code from the command line.
