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.

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)
