Magpie_trades 3 bottle-caps for food. High definition

This is current state of my experiment, trying to teach the magpies in our garden to pick up litter, and get paid with food. Right now, the birds pick-up bottle caps and trade them for peanuts in my machine. I plan to describe the evolution of his work together with plans and details of the hardware and software on this channel. There is also some descriptions and files regarding hardware for the experimental rig available on my thingiverse page :4601125
