I just sent out a PCB to fab: https://dl.dropboxusercontent.com/u/538662/dorkbotboard.png

It's an open-source pocketable e-paper device with an (Arduino compatible) ATmega, USB transceiver, Real Time Clock, FRAM, and coin cell Li-Ion rechargeable via USB. It also has five buttons along the top. Whole thing should be around 4mm thick. Repo here: http://github.com/Hylian/arducard

Some potential applications: QR codes, barcodes for rewards cards, Google Auth OTP, text terminal for a Raspberry Pi, etc.

Unfortunately, it seems I missed a certain small detail... https://dl.dropboxusercontent.com/u/538662/missedtrace.png
