What I’ve used RPi for:
- Finishing masters thesis when my PC died at most unfortunate time possible.
- Controlling 3D printers.
- Connecting old boring paper printers to home network.
- Making my dumb TV smart (worth noting that RPi also supports HDMI-CEC, so no additional remote required).
- Hosting all kinds of stuff - websites, web-services, gaming servers, Discord bots, git server, VPNs, Pi-Hole etc.
- Controlling radio transceivers (SDR).
- Controlling robots.
I’ve probably forgotten something. But yes - it’s a miniature miracle worker, that I used to throw at my problems. 🗿
