Helmet Light w/Adafruit Neopixil Ring
by NickRBrewer, published
I've always been a little nervous about riding my longboard around in the dark, so I decided to create a dynamic light for the back of my helmet.
It is an extremely simple circuit. I hooked up an Adafruit Neo Pixil Ring and connected it to a Trinket. Other than that it is a li-po battery and an on/off switch. Everything is hot glued on so it is semi-permanent.
All the code for the trinket and a wiring diagram can be found at - http://learn.adafruit.com/kaleidoscope-eyes-neopixel-led-goggles-trinket-gemma
Here's a video of it in action. - http://www.youtube.com/watch?v=3TjQS1vW82k&feature=share&list=UU_on_hqKOJJ1-vfrQzmIEeg
