Making a 8x8x8 RGB LED Cube

Published at : 23 Dec 2025

This video shows how the 8x8x8 RGB LED Cube was built. 512x PL9823 LEDs were used to make the 8x8x8 LED RGB Cube. It consists of 8 identical segments with 8x8 LEDs. The segments are attached with screws to the base. That means the segments can be removed easily in case of a faulty LED. All electronic components including the power supply are located inside the base. Please check the pinout of your LEDs before making the cube.
