The magic cube has 4 LED Panels and they interact dynamically with the onboard sensors that are on the PCB. This includes an IMU, Temperature sensor and a microphone. Everything is also very accessible and you can always get to the power supply so you can turn it off.

Wiring
From the Power Supply one power lane to the PCB and all others to the LED Panels. All components including the PCB and LED Panels need to have the same GND. Put the cables from the PSU to the PCB through the holes at the bottom.

Questions
How big is the Magic cube PCB?
It measures 89 × 91.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Magic cube use?
28 parts, built around the 74AHCT125D, LM2596S-5.0, MPU-6050 and ICS-43434. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Magic cube KiCad files?
From the Nils1024/magic-cube repository on GitHub, at the commit this page was made from: the board is pcb/magic-cube.kicad_pcb and its schematic pcb/magic-cube.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Magic cube design in my own project?
Its repository states no licence, so its author keeps all rights: ask Nils1024 before reusing the design.
