This is a view of an automated cat feeder I built for our cats, Oliver and Picasso. It’s a 5 gallon bucket mounted to a wooden stool with an auger made out of PVC pipes and a beach umbrella screw anchor attached to a servo controlled by a Raspberry Pi 3 Model B running MJPG-streamer. The build heavily drew from this tutorial. A systemd timer runs a little script that feeds them throughout the day.
