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.
A guys that I known did something similar: he bought lot of SMS unlimited SIMs, a bunch of cheaper chinese Android phones and he create an SMS gateway with this solution. After a while the telco start banning the phones from the network because they see an huge number of SMSs coming from the same mobile cell. Then he decide to spread the phones to friends and family, but after a while they got banned too. So he made an agreement with a friend that have a courier company and in every truck they put 20/30 phones sending SMSes all the time. Never got banned and he grow up the company until he sold it for 5 milion
