Arduino NeoPixel Earrings

Very few solder joints result in a very big impact. The ATtiny GND and PB2 pins are soldered to the Adafruit NeoPixel Jewel's GND and Data_Input pins. The Jewel's 2nd GND pin is brought on top of the IC. The Jewel's 5V pin is snaked over the top of the battery and back down to the Vcc of the ATtiny. It works with any 3V lithium coin/button cell battery. With a 12mA draw it can go all day on a CR2032. Programmed with the Arduino IDE.

Here is the work in progress.    • Neopixel RGBW strand test running on digis...
