How to Build a Redstone Computer in Minecraft Bedrock

Introduction: Understanding Redstone and Minecraft Bedrock

Redstone Minecraft Bedrock

Redstone is an integral part of Minecraft Bedrock that enables players to construct intricate circuits and devices within the virtual world. It serves as a power source, allowing for the automation of various mechanisms, and can be used to create impressive redstone computers. This article will guide you step-by-step on how to make your very own redstone computer in Minecraft Bedrock, providing a detailed walkthrough and explanation of the process.

Section 1: Basic Redstone Components

In order to build a redstone computer in Minecraft Bedrock, it is important to understand the fundamental redstone components. These components include redstone dust, repeaters, comparators, and buttons. Let’s take a closer look at each of them:

Redstone Dust

Redstone Dust

Redstone dust is the most basic component of redstone circuits. It is crafted by smelting redstone ore, which can be found underground. Redstone dust can transmit redstone signals to power other components and blocks. By connecting redstone dust in a straight line, you can create a redstone wire that carries the signal.

It’s important to note that redstone dust can only transmit a signal for up to 15 blocks. Beyond that, the signal will start to weaken and eventually disappear.


Redstone Repeater

A redstone repeater is a crucial component for extending the range of a redstone signal. It can delay and strengthen the signal, allowing for long-distance transmissions. Additionally, repeaters can also be used to create pulse generators, which are essential for building more complex redstone circuits.

To craft a redstone repeater, you’ll need three stones, two redstone torches, and a redstone dust. Place the stones in the middle row of the crafting grid, and the redstone torches above and below the middle stone. Finally, place the redstone dust in the bottom-right slot. You will obtain a repeater.


Redstone Comparator

Redstone comparators are versatile components that can detect various signals and provide analog outputs. They can be used to measure the strength or presence of a redstone signal, making them essential for creating more intricate redstone contraptions.

To craft a redstone comparator, you’ll need three stones, three redstone torches, and a nether quartz. Place the stones in the bottom row, the redstone torches in the middle row, and the nether quartz in the middle slot of the top row. This will yield a redstone comparator.


Minecraft Button

Buttons are used to provide a temporary and quick redstone signal. They can be placed on various surfaces, including blocks and walls. When a player interacts with a button, it provides a short pulse of energy that can power adjacent redstone circuitry.

To craft a button, you’ll need a single piece of stone, wood, iron ingot, gold ingot, or diamond. Simply place the desired material in the center slot of the crafting grid, and you’ll obtain a button.

By understanding and utilizing these basic redstone components, you’ll be well-equipped to build a redstone computer in Minecraft Bedrock. These components form the foundation of more complex circuits and contraptions, allowing for endless possibilities within the game.

Section 2: Redstone Logic Gates

Redstone Logic Gates

Logic gates are essential components in the construction of a redstone computer. They are responsible for processing and manipulating signals, paving the way for complex computations. In this section, we will delve into the creation of various logic gates, including AND, OR, NOT, and XOR gates, using redstone.

2.1 AND Gate

AND Gate

The AND gate outputs a signal only when both of its inputs receive a signal. It can be likened to the logical “and” operation, where both conditions must be true for the output to be true. To create an AND gate, follow these steps:

  • Construct two input paths using redstone dust. These paths will carry the signals to the AND gate.
  • Connect both input paths to a redstone torch. The torch functions as the output, and it will only emit a signal if both input paths carry a signal.

Once these steps are complete, you have successfully created an AND gate in Minecraft Bedrock edition!

2.2 OR Gate

OR Gate

The OR gate produces a signal when at least one of its inputs is active. It operates similarly to the logical “or” operation, where either condition being true leads to a true output. To build an OR gate, perform the following:

  • Create two input paths using redstone dust. These paths will carry the signals to the OR gate.
  • Combine both input paths into a single redstone wire. This combined wire will then connect to a redstone torch, serving as the output. The torch will emit a signal if either of the input paths is active.

After completing these steps, you will have successfully constructed an OR gate within Minecraft Bedrock edition!

2.3 NOT Gate

NOT Gate

The NOT gate, also known as an inverter, reverses the input signal. When the input path carries a signal, the output path will be inactive, and vice versa. The creation of a NOT gate involves the following:

  • Construct a single input path for the NOT gate using redstone dust. This path will be the source of the input signal.
  • Position a redstone torch adjacent to the input path. The torch should be connected to the output path. When the input path carries a signal, the torch will turn off, activating the output signal.

By completing these steps, you have successfully generated a NOT gate in Minecraft Bedrock edition!

2.4 XOR Gate

XOR Gate

The XOR gate, or exclusive OR gate, produces a signal only when its inputs are different. If both inputs are the same, the output will be inactive. To create an XOR gate, follow these instructions:

  • Create two input paths using redstone dust, which will serve as the inputs for the XOR gate.
  • Construct two NOT gates using the steps described in section 2.3, and connect them to one of the inputs each. This step is necessary to invert the signals of each input path.
  • Combine the outputs of the NOT gates and connect them to an AND gate, along with the original inputs. This AND gate will serve as the final output of the XOR gate.

After completing these steps, you have successfully constructed an XOR gate in Minecraft Bedrock edition!

Mastering these logic gates allows you to build more complex circuits and ultimately create a functional redstone computer in Minecraft Bedrock edition. Experiment and combine different gates to unleash your creativity and expand your understanding of redstone technology.

Section 3: Memory Units and Flip-Flops

Memory Units and Flip-Flops

In order to build a fully functional redstone computer in Minecraft Bedrock, it is crucial to understand the concept of memory units and how to create flip-flops using redstone. Memory units allow for the storage and manipulation of information within the computer. Flip-flops, a fundamental building block for memory units, are specialized circuits that can maintain a state or remember a value even after the source of the input has been removed.

To create a basic flip-flop circuit, you will need a couple of redstone torches, redstone dust, and levers. Start by placing two blocks next to each other. On the first block, place a redstone torch on its side, with the torch facing away from the second block. On the second block, place another redstone torch on its side, but this time, facing towards the first block. This creates a loop between the two torches. Connect the loop with redstone dust, creating a line between the two torches.

Next, add two levers to the blocks adjacent to the redstone torches. These levers will act as the input switches for our flip-flop. When the levers are in the on or off position, they will manipulate the state of the flip-flop.

To test your flip-flop circuit, try toggling one of the levers and observe the behavior of the redstone torches. When one lever is toggled, the corresponding redstone torch will turn off and the other one will turn on. This behavior is what makes the flip-flop circuit remember its state even after the original input is removed.

By connecting multiple flip-flop circuits together, you can create more advanced memory units. These memory units can store and manipulate multiple bits of information, allowing for more complex calculations and tasks within your redstone computer.

It is important to note that memory units and flip-flops require quite a bit of redstone wiring, and the complexity of the circuits can vary depending on the desired functionality of your redstone computer. Therefore, it is recommended to have a good understanding of redstone mechanics and familiarity with circuit building before attempting to create memory units and flip-flops.

Experimenting with different configurations and designs will enhance your understanding of memory units and flip-flops. By combining multiple flip-flops, you can create various memory capacities and expand the capabilities of your redstone computer.

Remember, building a redstone computer in Minecraft Bedrock can be a complex task, but with patience and practice, you can create incredible functional machines within the game. Take your time to experiment and explore the intricacies of redstone engineering, and soon you’ll be mastering the art of building a redstone computer.

Section 4: ALU and Arithmetic Operations

In this section, we will learn how to construct an Arithmetic Logic Unit (ALU) using redstone in your Minecraft Bedrock redstone computer. The ALU is a crucial component of any computer as it performs basic arithmetic operations and logical comparisons.

To begin with, let’s understand the basic components required for building an ALU. You will need redstone dust, redstone torches, repeaters, and observers. These components will help us create the necessary circuits for performing arithmetic operations.

Let’s start by constructing a basic 1-bit full adder, which is the building block for our ALU. A full adder takes two inputs (A and B) along with a carry (C) from the previous operation and produces a sum (S) and carry-out (Cout) as outputs. The circuit consists of XOR gates, AND gates, and an OR gate.

In the image above, A and B represent the inputs, C represents the carry from the previous operation, S represents the sum output, and Cout represents the carry-out. By combining multiple full adders, we can create an ALU capable of performing calculations on multi-bit numbers.

Now let’s move on to performing arithmetic operations using the ALU. We will focus on addition and subtraction, as they are fundamental operations.

Addition: To perform addition, we connect the two numbers to be added as inputs to the ALU. Each bit of the numbers is processed individually by the full adders within the ALU. The carry-out from one full adder is fed as the carry input to the next full adder. The sum outputs from each adder are combined to form the final result.

Subtraction: To perform subtraction, we use the concept of two’s complement. We convert the number to be subtracted into its two’s complement representation and feed it as input to the ALU along with the number to subtract from. The two’s complement representation involves inverting all the bits of the number and adding 1 to the LSB (Least Significant Bit).

By following these steps, you will be able to create a functional ALU within your Minecraft Bedrock redstone computer. Experiment with different arithmetic operations and expand the capabilities of your computer.

Remember to pay attention to wiring and connections, as even a slight mistake can affect the functionality of the ALU. Test your circuits regularly and make necessary adjustments to ensure smooth operation.

With the ALU in place, you have now completed a major component of your redstone computer. In the next section, we will explore memory and storage, which are essential for storing and retrieving data within your computer.
