Redstone Repeater

A Redstone Repeater (sometimes called a diode) is a redstone item that was added in Update 0.14.0. It is used in Redstone Circuits.

Crafting

 * 2 Redstone Torches + 1 Redstone Dust + 3 Stone Blocks => 1 Redstone Repeater

Uses

 * It is used in Redstone circuits to "repeat" Redstone signals to full strength.
 * It is used to delay redstone signals.
 * It is used to prevent signals from moving backwards.
 * It is used to "lock" signals in one state by facing a powered repeater into the side of another repeater (powered or non-powered).

Trivia

 * When the player taps the repeater, one of the redstone torches will move. It indicates that the player moved it by one tick. One tick is equivalent to 0.1 seconds.
 * By default, the maximum delay that can be created by a repeater is 4 ticks, equivalent to 0.4 seconds.
 * More redstone repeaters must be used in order to make longer delays.
 * Redstone Repeaters are often used with Note Blocks to make long length songs.
 * A large amount of Redstone was added in Update 0.13.0, however Repeaters were not added until Update 0.14.0 in Redstone's second phase.
 * Redstone Repeaters can be used to make a continous Redstone signal.
 * They are often confused with the Redstone Comparator.
 * There is a Redstone Repeater that is already powered, but it is available only through Inventory Editing.
