I’ve put together a kit that lets you turn an 8x32 LED pixel matrix into a smart clock. I use this with an ESP32 and the WLED software to display the current output and charge level of the solar system. But the system can display anything you can imagine or simply play animations to the current music. Assembly is super easy. Insert the display, place the honeycomb panel on top, and then slide in the 3D-printed cover. On the back, connect your ESP32 to the pixel matrix and the power supply, and you’re almost done. Just quickly secure the power cable to the strain relief with two cable ties, then close the case and screw it shut (or glue it).
For the front panel, I recommend Bambulab’s opaque transparent Jade White. Other white filaments don’t let enough light through. Attempts with transparent PETG just looked cheap.
