thingiverse

Here's a fun and easy programmable RGB drink coaster using the BBC micro:bit and a Kitronik ZIP Halo. Our example program features a chasing rainbow function at startup, then turns red, green, and blue upon shaking the Micro:bit. You can customize the code to perform other functions too! The coaster top is designed to be printed with a clear or translucent filament. The enclosure was carefully crafted to friction fit together seamlessly. A keyed notch ensures that it will only assemble in the correct orientation, while an opposite slot accommodates a flathead screwdriver for effortless disassembly. The bottom piece of the enclosure boasts two guides for precise battery placement and a convenient hole for external access to the power switch.
