Announcing Adafruit Gemma – Miniature Wearable Electronic Platform

Posted by Unknown on from the honey-i-shrunk-the-microcontroller dept.

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

    Yes but with only two PWM outputs all you get is two pixels.
    In a way I'm glad this stuff isn't too popular... womens sweatpants flashing out morse code "juicy" isn't all that appealing.

    With PWM support, I've bit-banged composite video with only a single IO pin.
    Also a lot of the new LCD/oLED controllers are a serial interface like i2c or SPI, which would be an option here too.

    Just combine this not-yet-available chip with one of those not-yet-available flexible/wearable oLED strips sewn into the ass of said sweatpants, and the juice is on.

    If you enjoy being fondled and yelled at while a nightstick is at your throat? Yes it is 100% TSA friendly.
