An older one as a PiHole for my home. A Rpi3 as an octoprint server for my 3D oeubter, including canera feed. A friend uses his as a HomeAssistant server to monitor and manage his home lights, temperature and garden watering needs. And I have one as a nifty remote KVM (TinyPilot) that we also use for work. Connect it to the Internet and a PC and you can control that machine remotely. Also use it as a Windows RDP thinclient. And to tinker on electronic projects.
