I don’t want to hear about your Plex, your NPM, your notes application or science forbid, your budgeting application. I want to hear the most exotic thing you setup to selfhost, that probably only you and a hand full of people around the world actually use or even need. A problem that you solved in a way, that makes people go WTF. Go!

I’ll start: I live in the mountains, and there is snow, lots of snow. I often tell people “We had 3m of snow last year”, but is that really true? So, I thought to myself: Can you measure snowfall? It seems you can, so I setup a USH-9 ultra sound measuring device, connected it via IC2 to my Home Assistant and now I can tell people with confidence, that we had a total of 3.45m of snowfall last season, with max snow height of 60cm on January 5th.

Future project: I have chickens. They lay eggs. I have cameras. I want to know which hen lays how many eggs. Solution? AI image recognition of the hens (who is who) and if they have laid an egg. Any inputs welcome.

When I lived off grid, I wrote an energy production measurement application. With both hydroelectric and solar going through a 1990s inverter, it was something. Nowadays these are off the shelf for suburban yuppies, but for my DYI-everything homestead, only DIY would do. Measurement was via shunts. I put it online over satellite internet and could watch my production and static consumption from work.

You built your own hydro? Tell me more!

From what I've gathered from youtube you'll usually need to create a height difference of some sort by damning up a bit of a stream, then have the overflow go through a pipe that's a sheer drop down onto an impeller attached to an electric motor (bonus points if it's recycled from something like a washing machine).

Then from that motor it's on to battery chargers etc....
