Questions & Answers

Q: How does the RGB cube work?

The cube consists of 512 lights connected together, and each light is controlled individually. Microcontrollers like Arduino or micro:bit can be used to program the cube's behavior.

Q: Can kids program the RGB cube?

Yes, the micro:bit is especially suitable for kids as it is small, cheap, and easy to code. Kids can use block-based languages like make code to program the cube with their own designs.

Q: What interactive games can be played on the RGB cube?

The maker has developed 3D snake and Pac-Man games for the cube. However, the cube is highly customizable, and users are encouraged to create their own games like two-player pong or 3D Tetris.

Q: How sturdy is the RGB cube?

The second version of the cube is more reliable and sturdy, thanks to the use of copper-coated iron rods for wiring. It has been traveled extensively without any issues, and it can be disassembled for transport in the car's boot.

Summary & Key Takeaways

• The maker has created an 8x8x8 RGB cube of lights, with each light sitting underneath a drilled ping pong ball for light diffusion.

• The cube consists of 512 lights connected like Christmas tree lights and can be controlled by microcontrollers such as Arduino, Raspberry Pi, or micro:bit.

• The maker emphasizes the importance of user customization, encouraging people to create their own games and designs for the cube.
