A free program…
This is the Python code I cobbled together to make a time-lapse movie of my rather exciting flowering cactus. I’m sure this has been done better by lots of people. It runs on a Raspberry Pi Zero, with not much memory, and no online storage, so it sends the pictures to another Pi Zero, called PiBigStore, which happens to have a 2 Terabyte USB drive. Help yourself to a copy, if you like. Change the server name, and password, obviously. If you know ways this can be improved, feel free to comment.
