The project shared this week shows off a way to play games on an LED panel using a handheld controller. Treloar tested the system with both a Nintendo Switch Pro controller and PlayStation 4 controller. Be advised, however, that this project is still in its Alpha phase, so updates are expected.
Treloar tested the creation on a Raspberry Pi 4, which proved to be the most reliable performance-wise. The system was also tested on a Pi Zero, which ran some games better than others but lacked overall in performance when compared to the Pi 4.
In terms of the housing, everything is entirely 3D printed. Treloar shared the model files on Thingiverse (opens in new tab).
The maker also developed a companion app, called the Retro Matrix Companion. This application allows you to interface with the RGB LEDs using an iPad. You can "paint" the LEDs in real-time over a local network. You can find the source files for the Retro Matrix Companion (opens in new tab) project on GitHub.
