TinyCircuits Thumby Keychain Console

A playable little console small enough to disappear among your keys.

The monochrome screen boots to a menu, the tiny cross responds to a thumb and the two red buttons really do play games. Connect it to a computer and you can write a game that has to fit inside this postage-stamp-sized world.

The blank pixels are part of the challenge. A character has to read as a character after just a handful of dots.

BEFORE YOU BUY

This is the original monochrome model. The buttons are genuinely tiny. The photograph is a close-up so you can see the screen and controls.

Grey original with red buttons and a monochrome OLED. The Thumby Color is a separate device.
