This is a 3D printed lamp in the shape of a Minecraft ore block. Powered by an Arduino Uno and four Neopixel LEDs. Model from Thingiverse: link
The button on top will step through different ore types:
- Lapis Lazuli
A final button push will turn it off.
The design on Thingiverse only contained code for RGB LEDs. In case somebody wants to use Neopixel (WS2812B) LEDs instead, the code for this project has been uploaded to Github: https://github.com/jonas-werner/minecraft-ore-lamp
Since the Neopixel LED’s are very bright I made a dome-shaped diffuser of transparent PLA. The sides are made of painted white PLA (brand: Priline) and the “windows” are transparent PLA. To give it some stability and to easily be able to mount / remove from the Arduino I used a prototype board to create a “hat” for the Arduino. That way it can easily be detached if required.
