Dr_Speed completed the GEMMA + NeoPixel ring pendant project!
Gemma board, Neopixel ring and LiPo battery for animated necklace pendant. Runs for hours on this battery, very bright. Only 3 wires to solder to get the hardware going. A bit of work to get this cross compiling on OSX, you have to do a bit of monkeying around to get the IDE going with the Gemma and you need to replace the ld.exe to get the sketch/library to work.
The Gemma and NeoPixel ring are from Adafruit and LiPo battery and charger (not shown) are from Sparkfun.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
