If you like making jewelry and have some experience using the Othermill, this is a great project for you! This style of necklace offers a wonderful way to get creative with double-sided machining on the Othermill.
The four LEDs on the back of the pendant provide a beautiful glow around the outline of the pendant and highlight the pattern on the front of the necklace by illuminating the etched traces.
This tutorial offers the design files for three different designs: a blank front, a circle design on the front, and the actual bird patterning on the front. Download these files in the next step!
Of course, feel free to use this technique to design your own pendants by mixing and matching your favorite shapes with your favorite-colored LEDs. If you do design your own unique necklace, please post pictures of it in the comments. All of us here at Other Machine Co. would love to see it!
Note: This is the first version of our Light-Up PCB Necklace. Check out V2 for an updated version.
