18 RGB LEDs under the skin, rechargeable, and bluetooth controlled
After seeing the northstar I had a bit of inspiration. I think the idea of the northstar is super cool! But not a very smooth execution. So I took some adafruit parts and made a bluetooth controlled LED ring with 12 LEDs on it. this was cool. It had a battery and qi charger and LEDs But it was not an implant by any means. So I took to eagle (learned eagle while making this) and I designed my own atmel32u4-mu powered bluetooth implant with 18 leds (the more the better right).
