You can/could also find Coffee HOWTO in your distro’s HOWTO package. (I found a reference back to v0.5 of the document in 1998.)

Has simple schematics.to get you started for the hardware, using the parallel port to toggle relays.

It’s a very neat little document, and inspired me to write a simple kernel module so I could echo 1 | sudo tee /sys/whatever/coffee0 to turn pin 0 high on the parallel port. (This is silly, and it’s much easier to just do things in user space!)

Cool, I recommend it!

I have my public facing reverse proxy point to my public services, and I also have it set up as a “roadwarrior” VPN to my home. So, I can connect my phone via WireGuard to my VPS, and a local DNS resolves my private services to the private IP addresses in my home network (so, I also run a reverse proxy on my server, for internal services).

I also have an off-site backup using this — just a raspberry pi and an HDD at family’s, that rsyncs+snapshots over the WireGuard network.

I’m sure I’m not following all the best practices here, but so far so good.

VPS with a public ip (which just takes all the fun out of selfhosting)

Why do you say this? My VPS only runs a reverse proxy and WireGuard, with all services hosted on my computers at home.

Maybe take a look at Outline. (Not affiliated, but I host it for myself.)

I also host KitchenOwl, but mostly just as a grocery list.

Seems more analogous to clothes than housing — clothes can be “too big” in the sense that the extra size is detrimental to the function, which is somewhat different from houses.

And it’s pretty common to have buy-nothing groups in cities or even at large companies. Got a loooot of hand-me-down clothes for my toddler from friends, family, and randos in the neighborhood.
