Welcome to Cubix

Cubix is a matrix LED display that turns your Cooler Master Cube 540 into a light painting canvas. Visualize static images, calendars, turning clocks, music equalizers, the GPU's current load, the status of the 3D print currently running through Prusa Connect or simply turn all the pixels on for a cozy ambient light. The possibilities are endless.

Concept

  • Cubix is designed fitting the Cooler Master Cube 540 computer case.

  • Cubix is mounted to the inside of the Cooler Master Qube 540's outer panels utilizing the factory screw holes.

  • Cubix can be powered through a 5 V line directly from the computer's PSU.

  • Each pixel is a commonly available WS2812B RGB LED that is already soldered to a breakout board.

  • Cubix's brain is an ESP32 C3 Super Mini board.

  • The pixels, the ESP32 and the pixel covers are press-fit into place.
