A Redstone Repeater (sometimes called a diode) is a Redstone related Block 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 (another 15 blocks).
• 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.
• If the player places a Repeater in one direction, then places another in a ninety-degree frame, the texture line going across the second Repeater will have the same texture as Bedrock. (as seen in the two pictures above)
• Redstone Repeaters are often used with Note Blocks to make long length songs.
• A large number of Redstone Items were 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.
• Repeaters can create temporary Airlocks if placed underwater.
• Before Update 0.14.0, since Redstone Repeaters didn't exist, alternative Repeaters were created to make complex Redstone circuits.
