A raspberry pi and a webcam go travelling.
I initially had this setup to monitor a blue-tit nestbox, but I was getting so many false-positives from the motion sensitive software that I had to change my plan. So now it’s moves around the garden pointing to wherever I think something might be happening.
At the moment it’s pointing at the bin of leaf mould. The leaf mould was going to be scattered as mulch here and there, but when the scattering began it became clear the the leaf mould bin was now a bee hive. So for the time being the bees have squatting rights.
