Happy Holidays!

The holiday season means different things to different people. In this case it means pointing the light ring, which has been aimed toward me during so many Zoom calls, towards something else. May I offer a nice Calabi-Yau manifold in these trying times? Happy holidays everyone!

Minecraft ore lamp

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:

  • Redstone
  • Emerald
  • Gold
  • Lapis Lazuli
  • Diamond

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.
