Helmet Light w/Adafruit Neopixil Ring
pinshape
I've always been a bit apprehensive about cruising my longboard through dark streets, so I decided to build a dynamic light for the back of my helmet. It's an incredibly straightforward circuit. I connected an Adafruit Neo Pixel Ring directly to a Trinket microcontroller. The only other components are a li-po battery and an on/off switch. Everything is securely attached with hot glue, making it semi-permanent. All the code for the Trinket and wiring diagram can be accessed at learn.adafruit.com/kaleidoscope-eyes-neopixel-led-goggles-trinket-gemma. Here's a video of it in action: youtube.com/watch?v=3TjQS1vW82k&feature=share&list=UU_on_hqKOJJ1-vfrQzmIEeg To assemble the project: Print on standard settings using MakerWare.
