\title{The Hinge}

This hinge contraption may be your best invention yet!
It resembles an ordinary iron block when closed,
but a narrow bolt of dark iron allows two heavy slabs to rotate up to a half-turn.

When placed, one half of the hinge will be securely anchored to the world;
blocks placed on the other half can rotate freely
when pushed or pulled with an empty hand.

Giving a good smack to the hinge block itself will make it slam shut.

A redstone signal will lock the hinge in place.

Comparators will measure how far open a hinge is.

The heftiness of the hinge allows the construction of much grander doors than those
rinky-dink wooden ones \#{item.doorWood}.

Only the first block you place needs to be attached to the free end of the hinge;
other blocks may be placed and removed however you desire, but no further than
8 blocks away from the hinge.

Sockets and servos function on hinge like you would expect, for the most part.
