Firefly Race

Firefly Race 2013

I built a heart-beat LED blinkie and Larson scanner with a Teensy, a Adafruit Neopixel ring and a lightbar of WS2812b for the Firefly 5k through Prospect Park. Instead of soldering, I used a double wrap of the wire through the hole and a knot to hold it in place. This held up quite well to the vibration of jogging. Source code is available if you want it.
