The birds have been making deposits every day for more than a month, except for 26-NOV when I did some balcony cleaning and spent a lot of time near the machine. I've been leaving the birds caps and butts around the balcony to use, and I think there are 3-4 jackdaws that fully understand what they are for. I'm going to let them run out and not provide them anything for a week or so and see what they do.

The weather has turned cold, windy and rainy - standard Dutch November. This means fewer people out and makes food a little harder to find. I expect this to motivate the birds a bit and hopefully drive them to find their own litter. If they do, that will be a big breakthrough for me - Stage 5. If I can get wild birds to do this I will have a much better shot at finding a municipality/university/etc. that will consider letting me place one of these in a park or square for a year or so.

I do need to get to work on the ESP32 port of the software and look into non-wifi IoT comms options in the meantime - it will be a much more attractive solution if I can power it reliably via solar and a ~20K mAh 5V battery and don't need a nearby wifi network.
