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 Adafruit.
There’s a video of it in action below.

Kaleidoscope Eyes (Trinket-Powered NeoPixel LED Ring Goggles): Here’s a project to dazzle onlookers at Halloween parties, cosplay conventions, raves or at Burning Man. These full-color animated LED goggles attract a LOT of attention! Adafruit NeoPixel LED rings fit perfectly inside the eyecups of most 50mm round goggles — a very common size. It’s almost as if these rings were made with this project in mind! (Actually, they were…then our clever customers came up with a million and one other uses.) (read more)
