3D Printed Cauldron

In this project, we’re making a Bluetooth controlled light up cauldron. This 3d printed cauldron is designed to house Adafruit Circuit Playground Bluefruit.

Bluefruit NeoPixels

You can change the color of the LEDs with an iPhone using the Bluefruit App for iOS and Android. This uses the picker color from the Bluefruit LE connect app for iOS and Android. It’s free to download, and lets you change the color and brightness.

Circuit Playground Bluefruit

The Circuit Playground Bluefruit features the nRF52840 and it’s easy to use with Adafruit’s CircuitPython and Arduino.

Light Up Cauldron 

The bowl is 3d printed in PLA filament without any support material. The design features internal threads for screwing into the bottom half of the cauldron. All of the electronics are secured underneath the cauldron so it’s a nice little portable project.
