jolliFactory have designed a single color 8x8x8 LED Cube aptly named jolliCube. It is designed for entry level hobbyist who wants to take on the challenge to build a bigger cube rather than settle for a 4x4x4 or 5x5x5 LED cube.
The electronic circuit for jolliCube is based on the MAX7219 ICs to drive the cube. This IC is originally designed to drive 7-segment LED displays. By designing our circuit based on this IC, the number of components to drive each 8x8 LED Matrix layer is very minimal.
It is designed to be modular in the sense that each of the eight 8x8 LED Matrix layers can work by themselves which makes troubleshooting easy.
Most LED Cubes are built as a whole so if one LED were to fail in the middle it would be very difficult to access and fix it. For our LED Cube design, we used a 5-way angle female header soldered to the first PCB and a 5-way angle male header soldered to the second PCB. This is to enable the 2 PCBs complete with LED Matrix layers to be connected together to work as well as to separate them apart for ease of access for replacement of faulty LEDs around the middle of the LED cube if the need arises.
Our design does not have any particular microcontroller embedded in our electronic circuit to drive the cube. It can be driven externally by any microcontroller via SPI interface using just 3 signal wires (SPI) and 2 power wires (5 V DC).
Note #1: LEDs are not included in the base kit set but can be purchased as add-on parts
Note #2: The kit set does not include the acrylic enclosure for the LED cube
