The Mondo Litter Box
Not every new use of technology requires a microcontroller. This one uses a 12 volt computer fan from CompUSA, a snap close food box from Walmart, some PVC pipe from Home Depot, and a large plastic storage container from Big Lots.
A large entry hole is cut in the lid of
the box. This type of entry keeps most of the litter from migrating out.
A 4 inch box fan is mounted inside the food storage box whose lid is screwed to the container and holes drilled thru the lids of both.
A one inch round hole is drilled in the base (now on top) of the storage box and a 12 volt dc wall-wart powers the fan.
Sections of 1 inch pvc pipe are cut and jammed together to route the odors out a nearby window.
Usually, there is no smell at all from
this system do to the constant outflow of air and really low humidity
here in Arizona.
Changing the litter out once a month works just fine. At least, the cat is not complaining.
