Minecraft Redstone Repeater

Minecraft Redstone RepeaterThe Minecraft Redstone Repeater is one of the more sophisticated items that can be derived from Redstone. There are three main functions of the Repeater which are explained next.

What is a Redstone Repeater?

The Redstone Repeater has three main functions, as it may act as a repeater, a diode, or a delayer. Don’t worry if you have no clue what these three things are, keep reading and I will explain them in a simple way (not all of us are Engineers :P ).

  • Redstone Repeater as a Repeater (duh!) – The main function of the Repeater is to continue the signal running through Redstone Wire, which lets it pass through 16 additional blocks.
  • Redstone Repeater as a Diode or Wire – When you place a Repeater, the back end is the side that is closest to you, while the front end is the opposite side. The Repeater will only allow a charge to flow from the back end to the front end, and will not connect to anything else adjacent to it. This comes in use when you are making Redstone Circuits that have wires in close proximity to one another. Rather than having two wires connect in areas that you do not want them to, you may continue the circuit without interruption by placing a Repeater instead.
  • Redstone Repeater as a Delay – You can use several Repeaters to create a delay. Initially a Repeater will have a 0.01 second delay, however if you right-click, it will change it to 0.02 seconds. This may be done up to 3 times (i.e. 0.04 seconds). You may also connect several Repeaters, which will allow you to create even longer delays. Initially Clocks and Redstone Torches were used for delays, however Torches may burn out if not properly calibrated, whereas Repeaters do not burn out.

How to Make a Redstone Repeater

The Redstone Repeater recipe is made from Redstone Dust + 2 Redstone Torches + 3 Stones. Place all three Stones in the bottom row, and the Dust in the middle of two Torches in the middle row. This exact combination of ingredients will output a Redstone Repeater. As you can tell, Repeaters are more expensive, however their uses are plentiful.

How to Use a Redstone Repeater

Once you have created and placed a repeater, you will need to charge it. You may do this by placing anyone of the following objects on the back end of it.

  • A Redstone Torch
  • An active Redstone Wire
  • A Repeater with the front end facing the same way
  • A charged Block
  • A Switch

Connecting the Repeater to a receiver (Wire, Block, etc.) will allow you to propagate the charge (transmit it in the same direction).

Stay tuned for more advanced functions of Repeaters, however in the mean time you are getting close to the finish of our Redstone Tutorial. Next we will take a look at the most advanced topic yet, which is Redstone Circuits.
