I gave an old Android phone a second life as the camera that watches my 3D printer

We inevitably have to upgrade our phones every few years, and you probably have an old phone lying around that still works, but you don’t use it. I have a Huawei P30 Lite that I’ve repurposed for many jobs over the years, and since I’ve had my 3D printer, its latest job is a CCTV that watches my prints or my cats when I’m away.
