Something like two years ago, I had a friend who wore a pair of Christmas light earrings around the holidays. They were the big bulby kind, and they looked so much like the real thing that she was constantly asked if they actually lit up. That got me thinking: how hard would it be to make a pair of Christmas light earrings light up?
The goal of this project was to create a pair of tiny light-up earrings that are totally unobtrusive and look and feel more or less like normal earrings. This involved creating the smallest circuit board I’ve ever made and packing it into a tiny case where none of its components would be accessible from the outside.
It’s also the first project I’ve ever made that can recharge its own batteries.

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.
