Tiny Charcoal Generator
Source]

It's supposed to feed its product back into the furnace to fuel itself. However, it was an April 1 (2013) posting, so it warrants testing. At first test: Looks like it will not accumulate any charcoal in the chest until both the furnace and the hopper feeding it fuel (level 2) are full. The hopper can be "stuffed" with four non-fuel items in its last four slots, as long as you leave the first slot open for fuel. Then the chest will start getting charcoal after two stacks of charcoal are produced, which will require 2-$1/4$ stacks of wood.

If more than 5-6 stacks of wood are available, another chest can be placed atop the upper hopper.

As usual, using a hopper to take product from a furnace forfeits any experience from the smelting.

Chicken Farm
This 3&times;4&times;3 mechanism can be set into the base of an egg farm as described above (the topmost hopper goes directly under the central pillar's top-slab), with a roof extended from the top of the central pillar. Turning on the lever disables the clock. With the clock disabled, incoming eggs etc. will fill first the bottom dropper, then the bottom hoppers, then the chest, then the hopper above it, for a total of 52 stacks total storage. Another chest can also be added over the other bottom hopper (making a large chest), for 79 stacks storage. The dispenser is purposely separated from the collection hopper/central pillar, to allow for the dispenser's variable aim and cut down on chickens in the hopper.
