The KeebCard, an open-source, low-power, mechanical switch computer keychain

This is the home of the KeebCard project. Originally designed as a business card, people loved it so much I decided to release a version of it as open-source (TODO: add a license).

The KeebCard is centered around an SSD1306-powered 128x32 monochromatic display and an ATTINY85-10SU. The code uses the wonderful Tiny4kOLED library to communicate with the screen via i2c. With 8 kilobytes of program space and 512 bytes of RAM, it’s a fun challenge getting anything to run on this thing!”
