Orange Pi 3b with dietpi.
I’ve had Big screen work before in Raspberry Pi 4 (even made a meme about back when I was tinkering around with different OS’s on it to see potential uses for my rpi), but Orange Pis are cheaper and the hardware is more open source, so I’m curious if I would get better responsiveness out of it. Plus the Orange Pi I have has 8gb too.
I believe it is.
Maybe if I sell Orange Pis with something like Plasma Bigscreen on them set up and ready to go I’ll make a website that also lists privacy friendly hardware alternatives with links, like these “dumb” TVs. Getting some ideas from these posts.
