I am Moana of Motunui. You will board my boat, sail across the sea, and restore the heart of Te Fiti.
Create your own Heart of Te Fiti necklace and make it glow using a coin cell battery and Adafruit's nOOds - little glowing noodles of light.
nOOds are very cool. They're little silicone-coated strands of teeny tiny LEDs. They're extremely flexible and easy to use. One nOOd works from a single coin-cell battery, with no microcontrollers or noisy inverters needed. These things are absolutely perfect for tiny, self-contained costume pieces. Add some magic to someone special's day!
The electronics build requires a little bit of soldering, so you'll need a soldering iron and accessories.
I've 3d printed my necklace using a resin printer, though you can easily use a regular 3d printer as well. Or, take a look online to find a premade one that you can modify. The electronics portion of this tutorial is really simple, and with a little creativity you can make just about any translucent necklace glow.
