Really special LED earrings by ch00ftech:
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.
