Iron Man Arc Reactor with Gemma MO and LED Rings

thingiverse

This project brings an Iron Man Arc Reactor to life through 3D printing. An Adafruit Gemma Microcontroller powers two WS2812 LED rings, which can be fueled by either a USB connection or a lithium battery. A case in the rear holds the battery and Gemma Microcontroller, making it fully portable. A button on the back allows users to cycle through patterns and turn off the LEDs. You might not notice from the pictures, but the rings are animated and display three different patterns. Full credit goes to Aelkaim for their 3D print design that I remixed to work with my existing parts and hold the Gemma Microcontroller. Print all components at a scale of 95% to fit the large LED ring. If you get different parts, you may need to adjust the scale accordingly.
