Announcing Adafruit Gemma – Miniature Wearable Electronic Platform

coop0030 writes "Open source hardware company Adafruit has announced a new tiny wearable electronics platform board called the Gemma. The Gemma is a tiny, 1-inch diameter and 4-mm thick package. It's powered by an Attiny85 and programmable with an Arduino IDE over USB. There are three available I/O pins, one of which is also an analog input and two of which can do PWM output. Gemma is currently wrapping up development, but should be available soon."

You can make them removable by soldering snap buttons onto the pads and sewing the backs into the fabric. You wire it up using stainless steel conductive thread. Here is an example: http://learn.adafruit.com/flora-snaps [adafruit.com]
