OpenMower
Let's upgrade cheap off-the-shelf robotic mowers to modern, smart RTK GPS based lawn mowing robots!
I had posted this several years back trying to figure out options in NA without much luck: https://github.com/ClemensElflein/OpenMower/issues/8
Sounds like the hardware platform isn't available anywhere at all now.

Project mention: Show HN: Proxmox VE Helper Scripts: Make managing your Proxmox homelab a breeze | news.ycombinator.com | 2024-11-12
I'm just going to repeat a bunch of what hughesjj has already said, but anyway:
OPNSense (as my household's internet interface), Unifi Controller (as my household's primary wifi), Jellyfin, Wireguard, Pi-hole, LMS[0], Frigate NVR (migrating off ZoneMinder, awaiting delivery of a Coral TPU to finalise this), couchdb (as Noteself[1] back-end), nginx (serving a handful of sites for my own entertainment), Mailu[2], Calibre[3], various other in-flight experiments (which Home Assistant will soon become, Bitmagnet DHT scraper).
Most of the above are docker instances hosted on a small number of VMs hosted on two (or sometimes three) physical machines running proxmox.
