Wearable Electronics - A small coat button

Once connected to power using conductive thread, this little thing (just 18mm diameter) will blink / fade its LEDs. Switching between modes is done by shorting the two marked pins before powering up the device.

I really don't know if this panel will ever see the light of day. The boards have MLF10 packages on them, and I'll have to see how assembly goes first! The prototypes were ordered at OSHPARK.

The right board looks really nice. I've already built it. However it was a PAIN to assemble by hand. Tiny 0603 parts too close together. It took me ages to complete. Too much effort to be fun if repeated. The left board still comes with the LEDS. They are the whole point of this board's existence. The tiny resistors however were replaced with easily manageable 1206 resistor packs. Assembling 4 large parts vs. 16 tiny parts with no room to move. Lesson learned.

I've shrunk down the fat capacitors to just 1000µF each, which made the board shorter a bit. I've also added larger headers + 1k series resistors (all 0603 now) for ALL I/O lines of the micro, so I can probe effortlessly without shorting anything. There are 5 new status LEDs as well. The main LEDs are now from Nichia and only need about 50mA per channel to get 20 lumen per piece. Total output should be about 600 lumen.
