This is a press-to-fit model. Its purpose is to house a custom LED array. It's sturdy enough to last and has ventilation to let the heat from the LEDs out.
You could use a Raspberry PI Pico, but I've got a LOT of ESP32s lying around :).
The LED array consists of 3 MAX7219 LED Boards and an ESP32.
Very minimal wiring is required, and the software to control the ESP32 is here.
It consists of a web server that lets you control the system from the command line. It has a few fun effects, like blinking lights, etc. You can store an array of messages of different types and timeouts, and the LED array will cycle through them.
