This composter rotates so that compost matter can breathe (which should also minimize odor) and break down a little faster. I created this prototype in about 2-3 hours. This project applies the fine art of meatball carpentry--emphasis on function NOT aesthetics. The materials should run about $10-$15. I don't know what the weight limit is for the compost matter.
UPDATE: There was some concern that the compost mass would be excessive (someone estimated 300 pounds). Currently, the cylinder is full with composting leaves and kitchen discards and it weighs roughly 35-50 pounds.
