I’ve been wanting to make a something themed as a mini Carbonite chamber for a while now, so a kyber crystal stand seemed like as good of an excuse as any. For the enclosure, I designed the top lid in Illustrator and lasercut the design out of black acrylic. (For LED diffusion under the lid, I used frosted white/milk acrylic.) The bottom and kyber holder were designed in Sketchup then 3D printed.
For electronics, I used an Adafruit Circuit Playground with a small LiPo for power, and I used the FastLED library for animations. In the future, I’ll add a hole to the bottom for a USB cable for continuous power.
