Pet feeders are a popular maker project. One can speculate that this shows the great self-confidence common to the maker set, who are willing to trust their own work to keep their animal companions alive for many days at a a time. [Darren Tarbard] is one such maker, who put together this simple auger build.
The project consists of a hopper for dry pet food, into which a screw auger is inserted. Both parts are 3D printed, making them easy to produce at home for the average maker. The build was designed specifically around the parts [Darren] had to hand, namely a 28BYJ-48 stepper motor, which is charged with turning the auger. Running the show is an Arduino, which can be run with whatever suitable timing code is necessary to feed the particular pet in question. There’s also a remixed version that adds a larger food storage dish on top for longer periods of unattended operation, created by [szuchid].
It’s a basic build, but one that would be readily achievable by most makers with little more than some junkbox components and a roll of filament. Of course, if your pet prefers wet food, you might need a different design. Video after the break.
