I don’t proclaim to have any knowledge of electronic engineering – at all, but I have a little more now. This guy builds a video card on a breadboard, and it’s pretty damned impressive (in a 1976 graphics kinda way), but has also taught me a thing or two. Well worth watching both parts.
Arch Linux, on a Ryzen 7 1800X, 32 GB, 5 (yes -5) HDs inc 5 SSDs, 4 RPi 3Bs + 1 RPi 4B - one as an NFS server with two more drives, PiHole (shut yours), Plex server, cloud server, and other random Pi stuff. Nice CoolerMaster case, 2 x NV GTX 1070 8GB, and a whopping 32" AOC 1440P monitor.
