Redstone experts guide you through all aspects of working with Redstone including mining, smelting, using repeaters, circuit components and circuit designs. This handbook--now with sixteen addtional pages of new content--also includes exclusive tips from game creator Notch himself and some of the most extraordinary redstone creations ever made. I expected more from "An Official Mojang Book". After a fairly good start with the Basics, only some basic projects are provided followed by advanced projects that would never be done by a beginner.

The content is very limited due to the small size. Redstone circuits and devices have many uses including automatic farms, controlling doorways, changeable or mobile buildings, transporting players and mobs, and more. Redstone construction can range from fairly simple to deeply complex.

These are essential in order to produce a functioning computer and manipulate data by performing computations. There are many methods of storing data, in Minecraft or in real life. The states of memory usually are binary, either on or off and can be computed with boolean logic.

On a computer, there are three types of storage. Keeping in mind that increasing the device's capacity would increase its size, each type would have speed and capacity appropriate to it. These are the storage which directly accessible to the CPU, referred to as memory and is fastest to access but usually is smaller in capacity for it to be addressed quicker. Fastest is the memory stored within the CPU.

These are registers and flags as they can be set almost instantaneously and do not require any address sent to it as there is only one byte stored in each register.

Redstone bits that can be toggled are extremely large but can be toggled within 2 ticks. This requires a very large amount of space but is perfect for caches and registers. The redstone is also required for logic gates not shown to set the bit, as in the images, sending an input would cause the bit to flip. The gate would take up more space. Registers could also utilize locking redstone repeaters and timing them correctly. This is explained below, in RAM. With the use of a computer clock, it may not be necessary to build registers.

Registers are useful when the data goes through the line before either the CU or ALU is ready to process it. Second to those are caches, which feed information into the processor.

In real life, they are separated into levels, each one with separate speed and capacities. It is useful for the same reason as the registers.

They are connected to three busses, data bus, control bus and the address bus. The control bus tells it whether it is being get or set. The address bus tells the RAM where the byte is. Refer to the Architecture of the Computer to understand this more in-depth.

RAM is very useful and could fully replace tertiary memory explained below because of its non-volatility in Minecraft. Volatile means that when power is lost, it will lose information. The RAM will not lose information unlike in real life, and therefore in an excellent method of storing information. The RAM in the first case is utilizing the locking redstone repeaters with the correct timing. This requires a bit of a plan but is very space-efficient.

The conversion of a bus to the lines in order to lock the redstone repeaters also requires setting timings. This is time-consuming, much more than the registers, however, it is very compact and efficient.

The address bus green would turn in binary to unlock a certain byte, either to be read or set by the control bus second line, on the left. Most often, making it volatile has no use in Minecraft, so the easiest way to make some is to use d-flip-flops and to add a reading and writing function. The bottom image shows instead of locking repeaters, it uses d-flip-flops which is much more space inefficient but simpler to build. D-flip-flops work more or less like locked repeaters, one input - if on, unlocks in until the input is off and the other will set it once unlocked.

The output can be read as a bit and with a NAND gate, be ignored or put onto the bus. This is gone over in detail in the second chapter, Tutorial on building a Computer. Excuse the texture pack. Volatile means that when the power is lost, it will lose information.

There is a very compact storage technique , involving redstone comparators with the ability to store up to 1KB, being practically sized. Real-world tertiary storage use a mechanism of mounting the memory which takes about a minute for each drive. This is used for archival purposes and for memory which is rarely used. In Minecraft, a system where shulker boxes are used and block in the shulker boxes must be sorted out by a sorting system to represent a form of data.

This can also be used to create removable storage. The aforementioned mods could speed up tick rate and eliminate this problem, however. This is the equivalent of a real computer's hard disk or solid-state drive. The technique of storing blocks of instructions called programs within memory is what allows computers to perform such a variety of tasks.

The apparatus employed by a computer for storing and retrieving these programs is the computer's Execution Model. This is more advanced, and is for inquisitive and curious readers. The Harvard architecture physically separates the apparatus for retrieving the instructions which make up an active program from that of the data access apparatus which the program accesses during execution. Note however that certain memory circuitry is necessarily larger for those who select a Harvard architecture.

Harvard architecture is very important. The von Neumann architecture uses a two-step process to execute instructions. First, the memory containing the next instruction is loaded, then the new instruction just loaded is allowed to access this same memory as it executes; using a single memory for both program and data facilitates Meta-Programming technology like compilers and Self-modifying Code. The von Neumann architecture was the first proposed model of computation and almost all real-world computers are von Neumann in nature.

The amount of information a computer can manipulate at any particular time is representative of the computer's data word-size. In digital binary, the computer's data-word size measured in bits is equal to the width or number of channels in the computer's main bus. The maximum sized number representable by a Binary encoded integer is given by 2 data-word width in bits - 1.

For example, a computer with a data-word size of 8-bit will have eight channels on its bus set of wires, connecting components and therefore, we can count up to 2 8 - 1. The amount of data a computer needs in order to complete one single instruction is representative of a computer's instruction word-size.

The instruction-word size of a computer is generally a multiple of its Data-Word size, This helps minimize memory misalignment while retrieving instructions during program execution. Each instruction would have its own specific binary string assigned to it e. Inside the computer, there is a Central Processing Unit not to be confused with the Control Unit CU , a component inside the CPU , which in real life, is a very small and powerful component that acts as more or less, the brain of the computer.

In Minecraft, it is difficult to compact it to the scale we see in real life so don't worry if it looks wrong. We will first be designing our 4-bit Central Processing Unit in the next chapter, as it is the most important thing in our computer with the Execution Model the method of communication and organization of the CPU in mind, talked about in this page, before, in the Execution Model section we can map out the construction of the computer.

The CPU follows a cycle four steps, fetch, decode, execute and sometimes stores to perform instructions. The CPU first fetches the instruction from RAM, decodes what it means the instruction will most likely be a number, and the CPU must find out what number it is , and once it understands what the instruction is, it will perform that action. This sometimes requires the data to be put back into the storage, therefore it will store the data. The cycle is then repeated. There are five busses in the CPU, each to carry information from one component to the next.

Busses are channels of redstone connecting each component. Since we are building a 4-bit computer, we only need four channels in our bus. These are the red and blue lines connecting the components inside the CPU. Notice that the blue buses have less than four lines, this is because they do not carry data.

Since busses can only carry data one way in Minecraft, due to repeaters only working one way , there are two buses connecting the CPU to the outer computer. Information from the ALU is passed through bus 2.

The CU cannot send data through this bus to the ALU because the bus goes from left to right and works in one direction only. The CU can send information back to the storage units though, and is used to set values of storage devices. The third bus is the address bus, which the CU can send the address of storage. This is where the information resides. For example, the CU asks for the address of the byte living in It sends the address through the address bus and the RAM will return the value of the byte through the first bus.

For example, one wire could tell the RAM to set the byte to the value to the data sent to it by the CU. Flags are notes which could be error messages. Adding 15 and 1 in 4 bits would yield 0 explained above and this is called a binary overflow.

For our case, we are running a fixed program and do not need to change the instructions. Inside the CU, it will then decode the instruction, which is normally a number, into a sensible action.

It will then perform that action and if the instruction requires, store the result into the RAM. To communicate with the RAM, for example, one wire could tell the RAM to set the byte the location of it is specified through the third, address bus to the value to the data sent to it by the CU through the second, data bus.

Arithmetic logic unit ALU will execute instructions sent to it from the CU and will compare binary numbers and communicate with the Control Unit. It can do simple addition and subtraction which can be repeated to do multiplication and whole-number division, outputting a whole number then division. Now we can choose from a range of designs of busses, each contributing to the aforementioned three key designing goals of a Minecraft computer. Memory is a set number of bits. In Minecraft, memory usually holds 8 or 16 bits, though bit memory computers have been successfully built before.

Each bit is in one of two possible states: on or off. Memory is a series of these on and offs, which can be used to perform certain tasks. Real-world computers use binary, which is a series of 1s and 0s. In Minecraft, the best representation is redstone dust : having a signal means "1" and no signal means "0". However, depending on how far away the redstone is from the memory storage, it is possible for "0" to be anything from signal strength 0 all the way to You can also design things to make "1" equal anything from signal strength 1 to Our normal decimal system is a number system in base Binary, the number system within computers, is in base 2.

To compare, take a look at the 2-digit number. In decimal, the left digit is the 10s digit. In binary, it is the 2s digit. For example in decimal, "10" is read as "ten". In binary, "10" is read as "two". There are two commonly-used methods of converting from decimal to binary:. Highest Bit First: This method requires a bit of intuition.

Let's use 42 as an example. We first start by looking for the largest exponential of 2 e. In this case, it's We then subtract that number from the number in question. Also, the very first bit from the left is a "1".

We then step down to the next exponential of 2 and see if it is less than or equal to our current number. For this example, the next one is We keep doing this until the number reaches 0.

Whenever the 2 exponential is less than or equal to the number, subtract them and the next bit is "1". If not, the next bit is "0". Lowest Bit First: This method requires no memorization of 2 exponentials. Instead, it repeatedly divides the number by 2, using the quotient as the next number, and the remainder as the binary bit. Keep in mind, though, that this method writes the binary number from right to left, as opposed to the previous method which wrote it from left to right.

Let's reuse our example, The quotient is 0, so we stop. This gives us our binary number as "". Same as the previous method. Variables are numbers, strings sets of characters or booleans true or false stored in RAM for the purposes of running a program.

For instance, booleans can be used to keep information if the program has reached a certain state. The following information needs to be kept about a variable: Its name, type number, string or boolean , and value. A variable's value can, as its name suggests, change. Operations can be done on variables. Variables are created while running the program and deleted from memory once the program closes. When a program is re-opened, the variables are re-created.

It is the same in Minecraft. Memory is where data for programs are kept. It is volatile It is deleted when the computer is turned off and is used for the program to store data.

For example, in a program that counts up from 1, 1 is saved to memory, 1 is loaded from memory and 1 is added to it to get 2. The ALU is one of the most important components in a computer, both in real life and in Minecraft. First, you must choose the functions you want to be able to achieve.

You must then build the unit with all the logic gates and math functions you want and a way to choose which one's output to display.

Busing is what allows the components of your computer to communicate with each other. It is usually important to plan where to build the components of your computer so that you won't have to create busing wires too long, or even worse, have no space to create busing, in which case you can remove the offending component and rebuild it an appropriate location, or use a mod like WorldEdit to move the component somewhere else.

Making one is simple. You can make 1 flip-flop and then just stack it for as long as needed, with one block taken of each byte. See the following plan for help:. Tertiary memory is used to compactly store large amounts of data at the expense of speed. This kind of memory consists of the database, where all the data is actually stored, and a physical mechanism, usually a robotic arm, that must physically move around the database to fetch data.

For this reason, it is extremely slow and is only used for information that is rarely accessed. In the latest versions of Minecraft, it may be possible to create tertiary memory with sticky pistons combined with slime blocks , which can create "ships" that move around, and presumably store a Redstone component that can extract, read, and write from a wall of conducting and non-conducting blocks.

The program counter is used to keep track of which line of code the computer should be reading from. During each clock cycle, the decoder will access this counter in order to fetch the next instruction to be executed.

Some instructions will access a different amount of data than another or no data at all, so the decoder will in turn increment the program counter by the appropriate amount to the next instruction. The counter is also used by jump instructions to control program flow. In real life, this counter isn't a component by itself and is simply a register right next to all the other ones. In Minecraft, however, it may be less confusing to create a separate register apart from the others to store program counter data.

The control unit is the section of the computer that interprets the instructions, and controls the other parts of the computer, such as telling the ALU whether to add or subtract. ROM is most often used to perform a series of tasks remotely such as a program, hence the name. It can be made to be used on user control as in the picture or with a clock and sufficient delay between each line so 2 aren't on at the same time.

One of the simplest and most efficient design is the one in the picture, which may or may not be coupled with a decoder. It can be enlarged easily, which is another advantage.

Here is some tips:. Redstone clocks are used to synchronize components or to time them. In most Minecraft cases, it is possible to avoid the use of one but sometimes it is necessary for the computer's functioning. Minecraft Wiki Explore. Main Page All Pages. Minecraft Wiki.
