“It’s finally time I document this project I completed almost one year ago. I wanted to play with large led displays for a long time (who doesn’t ?), and browsing on AliExpress, I once landed on one of those WS2811/WS2812 addressable led strips for less than 3 EUR/meter, and thought “Wow, that’s dirt cheap !”. I bought one meter just to play with it, and was surprised to see how fun it was (easy to control and quite powerful), and I started to think about wiring them in a matrix shape. Most of the libraries already support custom width and height, so that’s pretty cool.”
