poster VS MagicMirror

I'd try posterr I haven't used it (it's on my todo list) but I think it will accomplish what you are trying to do

posterr

I don't think what you want exists in an easy setup. The easiest thing might be to just run a full Raspbian image with the desktop environment, then install headless plexamp and use one of those now playing poster plugins and just leave the browser on that page. https://github.com/petersem/posterr. I think this is the one I used before and it wasn't that bad to setup.

I installed posterr on my machine. Then installed a browser on the tablet that will allow a full screen. (Full screen browser, if you're on Android) then just loaded up the posterr interface on the tablet. Finally taped that tablet into a picture frame. Turned out pretty well, if you ask me.

there's an *arr for this: https://github.com/petersem/posterr

Also, as an aside, Posterr (with an e) already exists and does something different than what you are wanting.

Haven't tried this but I've seen it posted here before: Posterr

I use MagicMirror to do this. It's a great piece of software. I'm a bit shocked nobody has mentioned this yet. https://magicmirror.builders/

The most used solution it’s https://magicmirror.builders/

I’m planning on using MagicMirror (https://magicmirror.builders/) to do this in my kitchen but without the mirror part (just a TV mounted in a niche on the wall). Did you build your software from scratch?

Check out Magic Mirror. Could be what you're looking for. https://github.com/MichMich/MagicMirror

Would this work with magic mirror?

If so I will order right away

Have a look at the Magic Mirror project https://magicmirror.builders/

You could also look into something like MagicMirror. not sure if you have a server to host, or looking for just local on iPad.

The final option seems to be basically homebrewing a solution using a program like MagicMirror and local image files installed on the pi. There quite a few guides out there on different ways to do this. But

You can still participate in distributed computing projects, just check out Science United which is one that uses BOINC for the project management. I've got it running on my Raspberry Pi (which primarily runs Magic Mirror so its nice to let somebody else get some benefit since its primarily a relatively static display). Also, Folding@Home did do some of the research into COVID, so it is staying up to date.
