Autarchic Gate

Autarchic Gates are devices which attach basic electrical logic onto s and s.  Unlike normal s, which can only provide the Redstone Signal and  reactions, Autarchic Gates also have the Energy Pulser and Single Energy Pulse reactions. These allow the Autarchic Gate to act as a weak engine, moving items or pumping fluids through the attached pipe. Autarchic Gates come in several versions; the standard Autarchic Gate, and Iron, Gold and Diamond AND and OR variants on it, which have increasingly more options.

Recipe
Autarchic Gates can be crafted with an Assembly Table, using at least one Laser. They require a simple Gate, combined with a and a.

You can switch between Autarchic AND and OR gates, like you can with normal gates, by putting them in a crafting table, together with a Redstone Chipset.

Usage
Held Autarchic Gates can be attached to a Transport and Waterproof Pipe segment by holding them, and right-clicking the pipe segment. They can be removed instantly from a pipe by shift-right-clicking the pipe with empty hands. Autarchic Gates are dropped if a player breaks the attached pipe.

Once placed, right-clicking the Autarchic Gate will bring up a Gate interface. On the left side of this interface is a group of boxes for conditions, and on the right side, a group of boxes for reactions. See BuildCraft Gate Logic for further details on Gate Conditions, Reactions, and examples of OR and AND Gate Logic.

Active Gates will glow red. Autarchic Gates in Pulser or Single Energy Pulse mode can act as engines to extract or pump liquids. They provide slightly less energy than even a Redstone Engine, however, although they can respond more quickly to redstone signals.
