This is my simple D.I.Y. man powered Compost Tumbler/Trommel/Sifter/Sieve. Made from two free warped bicycle rims, some 3/8th inch hardware cloth, some scraps of wood, four rotating casters and a wack of zip ties. It sits right on top of my wheelbarrow to boot. Also works well with removing rocks from dirt.
It might evolve into a powered automatic one like the others you can find examples of, but for now it sure beats shaking a square screen and putting your back out.
