This Raspberry Pi project can identify stray cats in your garden, and safely scare off birds if need be

View through a window. On the window pane is taped a thin rectangular device with a brown data cable hanging down from it. In the background is a red wooden deck with a folding chair. Under the chair sits a black cat hovering near a food bowl, and looking up at the window.

I like this project not only for the recognition and photographing of stray cats (or maybe to identify neighbours’ cats straying into your yard), but the bird “scaring” part is nice and safe to use if you have a problem with birds sitting on your window sill and setting off your alarm beams.

The project can probably be adapted for other purposes too.
