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.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
