I started hosting an image board out of my house, in the past I've also hosted space station 13 servers. Hosting things from my bedroom has become a hobby of mine.
My ss13 is closed now due to disinterest and lack of a player base.
I'm in the process of setting up a home NAS.
I get a big thrill out of connecting to my homelab from my phone.
What else can I host from home that might actually be useful?
A forum.
A library.
A personal cloud drive.
A wiki.
Git forge.
Fediverse microblog.
Communications (XMPP/Mumble/email/IRC.)
Icecast Radio.
