Minecraft Ore Lamp - Customizable Size and Pixel Density

My seven-year-old kid is obsessed with Minecraft, so I decided to build something related for him.
Looking for options, there's a cool lamp project from Dan J Hamer in Thingiverse, but after tweaking it a bit I decided to start my own project (you know, the "not invented here" syndrome).

The results are really cool! With one button he can switch to all the available ores (except coal, which I told him is just the lamp switched off).

• 1x arduino board (Uno or Nano are fine)

• 2x PLA filament (gray for the main body and translucid for the difussers). Other projects are using tracing paper instead of the translucid pla, and looks cool too.

• 1 push-button

• 1 300-500 ohms resistor (for the data input pin of the strip)

• 1x 1000 µF capacitor (to protect the strip from sudden changes in corrent)

• 1 led strip (a 5v and 1m/144leds in my case)

• Typical maker materials (glue, dupont wires, self-solder connectors, M4 screws, etc)

Download the code from the github repository.

There's only a simple arduino sketch file, but the project has been created using the Platformio IDE.

If you are not using the Uno board, you'll need to change some parameter values inside the platformio.ini file

Couldn't been easier: power the board and led strip with a 5V USB cable, and connect the push-button and the strip input to the designated board ports.

Remember that to avoid damaging the strip, it's recommended to add a capacitor and a resistor to it's connection.

As you can see, the maximum corrent drawn is 1.2A, so you can connect the lamp to any decent usb plug.

You can access the Fusion 360 project files from here or download the STL files from Thingiverse

I've used parameters to make easier for others to modify the models according to their needs, so it should be pretty easy for you to modify the size of the lamp or the pixels density.

For my needs, I made room in the pillar for the Arduino Uno and merged this base to place the board before creating the STL file.

Just add supports :)

Also, you'll need to print 5x of the difussers. Two of them have to be cut to make room for the shade lateral supports.
