I am looking into controlling aprox. 25.000 LEDs in LED strips (WS2812B or SK6812) from vvvv. As far as a quick search tells me, I can either get some quite expensive controllers like: https://www.enttec.com/?main_menu=Category&cat_id=8 or some DIY project with a lot of arduinos.
Isn’t there a middle ground where I don’t have to build my own controllers and don’t have to buy relatively expensive controllers to control cheap LEDs?
