Firefox plus ublock origin, then just open youtube.com
I only use onshape. It's all web based so it works with any OS.
Just a picture of the x500 under construction. It will carry a rpi4 as the SBC.
I'm looking around for a SBC too, under 100$. Can't find stock of banana nor orange Pis. So i forgot about those. I like the features of the odroid boards, and the radxa rock boards. I'll probably buy the rock 4; seems like a good option.
