This project was requested by Adafruit. Their call was for a device that was easy for a novice to put together, featured some cool electronics, and could be worn as a fashion statement. These glowy crystal knuckles were created in response to that call. All of the custom components for this project are printed on a consumer-grade 3d printer sans support material. Even the mold that generates the glowy crystals prints in that same batch, making the project very easy to set up for first time 3d printing enthusiasts. The knuckle ring contains a Li-Po, a Power Backpack, a Trinket Pro for the brains, and three RGB LED’s. The LED’s cycle through a rainbow at a slight offset to give the ring a mystical glow that is diffused through the cast silicone crystals.
