I had a blast learning and configuring vlans for my smart switch and putting all the IOT devices on their own network.

PiHole, Plex and the related “*arr” apps. I also self-host my home automation platform (Home Assistant).

Some security camera systems have this built in. They show snapshots of various times where you choose the total period, say 24 hours. Then you glance through the snapshots that are all displayed at once on the screen and click on the last one where your bike was still there. That will then “zoom in” the timeline and show another set of snapshots, though this time within a smaller total time window. Keep clicking on the last panel with the bike, and it will soon show you the clip of the bike being stolen.

Really helpful to find out when something changed.

One runs Home Assistant (Pi4), and an older one runs RetroPi (Pi3) for my arcade cabinet.

I have another Pi3 that I used to use as a Steam Streaming device to put my PC games on the projector.
