Inspired by the Swedish Julkalender 2016 and Trollhunters, I created this amulet. It doesn’t detect trolls, but it does glow.
I 3D modeled the exterior and had it printed in aluminum. Then I created the electronics inside: An Adafruit Neopixel LED is controlled by an Attiny85 and powered by a small lipo battery.
