Using a raspberry pi and a lcd display i setup an app to download new cards and have the pi display them like a photo frame.

On each reboot it will download new cards

Using a cron job you could configure weekly updates.

16gb card help 14k cards with 8gb free to fill.

It was a fun project and showing off cards is always fun.

Works with pi 0, pi3 and pi4.

Have not tested others.

Source is on github for my app and I use FBI to display the image from the console. I use autologin and kick off on login.
