smartbutnot shared their RGB smart girder build on GitHub:
This is based on the Adafruit Matrix Portal, you will also need:
ome RGB matrixes from your favourite online supplier (they’re crazy cheap from Ali Express, less so from elsewhere). This is 4 64×32 panels in a chain.
A 5v power supply – conventional wisdom would be at least 10a, but I’m running all this on a self-contained little 3a plug because I’m not lighting up that many pixels
Some wiring to connect 1 and 2 together
Some arcylic diffusers to make the display look nicer
An MQTT server to serve up the values to display. I haven’t put up the code for that because it’s a mess of cron scripts and all sorts, but a lot of it can be published straight out of home assistant.
