Jarek tipped us with his latest project, an E-paper screen shield kit for Teensy. He writes:
E-paper screens have been hacked out of Kindles and store price tags for a while, but this is the first ( to my knowledge ) open-source project which offers a simple and cheap interface for E-paper. After you prototype your idea with this board, you can get the plans from my project page and integrate the solution into a project or commercial product without having to iterate fives times as I have to get the E-paper driving circuitry just right. The shield fits over most Teensy boards, and the female headers mean you can plug wires right into a breadboard or any other 3.3V microcontroller board. E-paper is sensitive to temperature, so there is an I2C sensor on board that can be used if you need to use your E-paper in harsh environments.
