I just got a Raspberry Pi 4. Does anyone have tips/tricks/recommendations for projects to try out on this new machine?

Does anyone know if there is a mastodon server specifically for DIY musicians in US? I'm interested in the potential of starting one for my local scene in Chicago, and potentially beyond.

Fosstodon
