Pet Feeder

thingiverse

This is the expanded version of the automated dog feeder for larger dogs. I see no issue in creating a customized plate that fits over the front half of the auger to prevent blockages due to hydrostatic pressure from dog food. The end attachment requires modifications, including an optical sensor and jam detector, as well as a reverse-optical sensor that needs to be enlarged. Additionally, the screw on the corners must be filed down for smoother operation. The stepper coupler is excessively tight and needs to be drilled out slightly on both sides by setting it against the sides and spinning the drill. Before inserting the motor into the hopper, pre-assemble the two pieces together with bolts. For added features, consider integrating a sound sensor that alerts you when food is ready or even teaches your dog songs through tones. Alternatively, install a limit switch and press a button to control the amount of food dispensed.
