This is an adaptation of a laser-cut version that you can find on hackaday .

Because I don't have a lasercutter of the needed size I decided to create my own 3D printable smaller version (dimensional wise) with a bigger resolution (20x10 leds).

I think a raspberry pi would be a little overkill, I opted for the ESP32 Dev controller board in conjunction with Glediator and ArtnetWifi.

Watch it here and here in action.

I also added the glediator config file for the 20x10 led matrix (glediator_led_matrix_20x10.gled) and the Arduino source-code.

I filled the bottoom part of the lamp with epoxy-resin mixed with metal powder to make it heavier. Otherwise the stiff power-cable would pull the whole lamp down from wherever it stands.
