Self Sifting Cat Litter Box

I made this project as a proof of concept for an automatic self sifting litter box. This version works manually by rotating the drum by hand to move the litter through the built in grate. I built the box using spare materials from work. The frame is wooden and the body is made from coroplast sheets rolled around the wood frame. As the drum is rotated, the litter is automatically sifted and droppings are deposited from the hole in the top of the drum into the waste basket. This was a fun side project and successfully proved the concept. I originally planned on adding a motor and microcontroller for a version two, but nowadays automatic litter boxes can be found for much cheaper. I still learned a lot from this and am happy with how well it works.
