Yeah, there is a guide for the raspberry https://www.raspberrypi.com/tutorials/raspberry-pi-tv-ambient-lighting/ I donk know if hyperhdr would run on weaker, more readily available hardware than the pi 3. ive seen some YouTuber (dont remember who) use Hyperion with a Pico, but here was noticable delay. Since hyperhdr is a more optimised fork of hyperion intended for 4k content, the pico may be able to to run hyperhdr for 1080p content, but im not willing to take that risk. Also check what kind of power supplies you can even get. 5v 15a power supplies apparently don’t exist in Germany, so i had to use 30 led/meter strips instead of 60
