In this guide, you’ll learn how to build a bright glowing light that can be used for cosplay elements, decor and wearables. The circuit and components are fully contained in a 3D printed cylindrical enclosure. An integrated switch allows you to turn the circuit off without having to take it apart. The circuit is powered by an Adafruit GEMMA and a small 150mAh lithium polymer battery. The NeoPixel Jewel contains 7 individual LEDs that can be programmed to display different colors and animations.
