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.
I do work for multiple organizations and got tired of having to disconnect/reconnect VPN tunnels each time.
Solution: Raspberry Pi. It’s got a single Ethernet port on it which makes it perfect. I used Openconnect since it was compatible with Cisco and PulseSecure (at the time). When you establish a tunnel, the routes come in as “kernel routes” assuming you have a split tunnel. I configured IPTables to NAT masquerade out each interface and I set up Quagga, a routing daemon to talk to my main gateway and redistributed my kernel routes into OSPF. That way, any of my devices can now access any networks they need. I did also have to configure my own DNS server since I needed to resolve the different private networks.
