Hi all! At the age of 15, I became obsessed with the idea of ​​​​creating a paper computer - a full-fledged mechanical computer created from paper, cardboard and toothpicks. What struck me was that paper has been around for over 2,000 years, but until now no one had bothered to create a paper computer.

All the mechanisms were developed by me, with the exception of the “AND” valve, the idea of ​​which I borrowed from one of the mechanical Lego computers.

Signal transmission

Signals in the car are transmitted using the piston principle. When the block is offset by one unit of length, a positive value is transmitted, otherwise zero.

NOT

AND

OR

XOR

RS trigger

Decoder

Delay line

The delay line is controlled by the machine operator using the appropriate lever. When you need to continue the signal, the red light comes on, otherwise the green light comes on. The delay line can be used to continue the signal over long distances if the paper power is not enough.

Well, what child doesn’t dream of his own laptop, like his mom and dad? All children want to have access to a personal computer, but we parents don't like to let them near it because it's not very useful. Children have no use for real computers; they only damage their eyesight. But why not make the kids their own little laptops? Make them together and the children will be happy! This craft will be very interesting for them.

To make a laptop that will even fold and unfold, just like a real one, you will need:

• large piece of thick cardboard
• scissors
• black paint with a chalkboard effect (you can use this paint with crayons, but if you couldn’t find such paint, you can also use gouache)
• tassel
• crayons
• ruler
• pencil

Let's do

First, measure out a piece of cardboard from which the laptop base will be made. Cut out this part. Then mark the center so you can bend the laptop. Cut a little with a stationery knife to make it easier to fold. You can do it another way: completely cut this piece of cardboard into two parts, and then join it with adhesive tape so that these parts also bend freely.

Now cut out three more small parts from cardboard: for the keyboard, screen and mouse. Even smaller parts will be needed for individual keys. Cover these parts with black red and let dry. Later we glue all this to the main part of the laptop.

Now we begin to decorate the laptop. For example, you can make a name plate with the child's name.

At summer computer school, we sometimes invite children to assemble a “biocomputer,” that is, a computing device from what is literally lying under their feet. Since children do not know very well how computing devices work, they usually end up with something like a spoiler picture. But some still do abacus or abacus.

Biocomputer

And recently I came across a description of a computer model made of paper, developed in 1968 at Bell Labs. The computer is called CARDIAC (CARDboard Illustrative Aid to Computation), which roughly translates to Cardboard Visual Aid to Computation. That is, in fact, it is not really a computer, since a person acts as a conductor of signals, as well as an arithmetic-logical device in it. However, it does provide insight into some of the principles underlying modern computing. In addition, after a short search, I found a description and materials for making CARDIAC.

How does a computer work?

CARDIAC consists of two blocks - memory and processor. Several paper strips are inserted into the processor unit with the help of which you need to select the instruction to be executed. In addition, a tape is inserted into the memory block, where the output occurs, and a tape with input data is inserted into the processor.

Memory

The computer has 100 memory locations with addresses from 00 to 99. Each of them can be used to store one instruction or one three-digit number. Any of the cells can be overwritten, so you can even write a self-modifying program if you wish. Values ​​in cells are entered using a pencil, and modified using a pencil and an eraser. At the same time, the value 001 is always “stitched” in cell 0. It is very convenient to use for increments, since the computer does not have commands with direct argument values.

This is what the original memory block looks like:

Instruction counter

The original uses a ladybug as an instruction counter, as in the picture above. It is inserted into special holes punched in each memory cell. Since I didn’t want to make 100 holes, I used another ladybug to indicate the command counter - I simply placed it on the desired cell.

Battery

The only register in a computer is the battery. It is used to perform arithmetic operations (addition, subtraction, shift), as well as for conditional jumps. Unlike memory cells, an accumulator can store 4 decimal places.

Command system

Each instruction is encoded using a three-digit decimal number. The first digit is always the operation code. The remaining two digits usually represent the address of the cell that the instruction operates on.

CARDIAC can "execute" 10 different instructions (codes 0 to 9):

• 0 - INP - enter a value from the input tape
• 1 - CLA - loading the contents of a memory cell into the battery
• 2 - ADD - adding a memory cell to the battery
• 3 - TAC - jump to a given address if the accumulator value is negative
• 4 - SFT - shift operation left and right by a specified number of decimal places
• 5 - OUT - output of the memory cell to the output tape
• 6 - STO - writing the battery to a memory cell
• 7 - SUB - subtracting a memory cell from the battery
• 8 - JMP - unconditional jump to a given address
• 9 - HRS - stop and reset

Making a computer

I printed out the included materials on thick paper, cut out all the necessary holes, inserted the moving strips inside and glued both blocks.

How does it all work?

The functioning of a computer consists of sequential execution of instructions. Before starting execution, you need to look where the ladybug is located (that is, the instruction counter) and, by moving the strips, enter the value from this memory cell in the “Instruction Register” window.

Then you need to follow the arrows, starting with the inscription “Start” and follow all the instructions. For example, in the picture below, you first need to advance the instruction counter forward, and then add the contents of cell 41 to the accumulator.

Of course, calculations (addition, subtraction and shift) will have to be done manually. To do this, next to the inscription “Accumulator” there are several windows that allow you to perform addition/subtraction in a column.

Example of computer operation

To begin with, I “entered” (that is, wrote with a pencil into memory cells from 17 to 23) the first of the programs given in the manual:

This program adds two numbers read from the input tape and writes the result to the output tape.
The input instruction reads a value from the input tape, writes it to the specified location, and then moves the input tape forward one step so that the next value appears in the Input box. In this case, you will have to use a pencil (and possibly an eraser) to write the value into the memory cell.

After executing this program with input values ​​42 and 128, the memory state became as follows:

"Performance" of the computer

What's a computer review without benchmarks? I took the following program from the manual to multiply two numbers.

Address	Meaning	Decoding
07	068	Enter values ​​in cell 68
08	404	Zero the battery by shifting 4 to the right
09	669
10	070	Enter values ​​in cell 70
11	170	Load cell 70 into battery
12	700	Subtract cell 0 (that is, the value 1) from the accumulator
13	670	Write the accumulator to cell 70
14	319	If the accumulator has a negative value, then go to address 19
15	169	Load cell 69 into battery
16	268	Add cell 68 to the accumulator
17	669	Write the accumulator to location 69
18	811	Go to address 11
19	569	Output cell 69
20	900	Stay

I ran this program for inputs 5 and 3. There were 34 instructions to execute, which took me just under 15 minutes. Therefore, the instruction frequency for this computer (included with me) was about 38 MHz (not to be confused with MHz).

Contents of memory and output tape

Other programs

The creators of CARDIAC took the issue seriously and developed (not counting those listed above) the following programs:

• A program for “reversing” the digits of a number
• Bootstrap for loading programs from the input feed
• Mechanism for calling subroutines
• A program for playing Nim with one pile (that is, the game Bache)

Video demonstrating the original:

Paper and cardboard are universal materials for a wide variety of crafts. It is not at all necessary to master the origami technique perfectly. Even a child can do some original and funny things. Don't you know how to make a notebook out of paper yet?

Deciding on the size and purpose of the craft

Why make a paper model of a computer? There can be many options - a simple toy for a child, an accessory for his doll, a postcard for an adult lover of high technology, or a comic gift. Only the size changes, and the basic step-by-step instructions on how to make a notebook out of paper are the same for all crafts.

It is not difficult to guess that the doll and the child himself need computers of different sizes. If you are making a card as a gift, choose an arbitrary perimeter of the blank. An interesting idea is to make a model of a laptop and give it as a gift in a box from a real PC. Just keep in mind that such a gift should only be given to a person with a good sense of humor. If you have doubts about the recipient's reaction, abandon the idea.

How to make a laptop out of paper with your own hands?

You will need two sheets of paper or cardboard of equal size. We connect the base and lid using tape or thread. We have the preparation. Now is the time to start decorating it. The keyboard can be drawn or glued from individual paper “buttons”. We make the display in the same way. We draw it on the inside of the lid or glue it. A paper laptop can display a search engine page, desktop, or the gift recipient's favorite website. You can make the screen replaceable. To do this, glue narrow strips to frame it. The top piece of paper or cardboard needs to be secured only at the edges, leaving a hole through which new images can be inserted.

Ideas for decorating a paper notebook

You can use an empty candy box with a lift-off lid as the base for this craft. Another interesting idea is to make a voluminous notebook out of paper with your own hands. To do this, for the side edges you will need rectangles made of the same material as the base. Bend each rectangle twice and glue it to the base. You should also leave a free strip of paper where the lid bends to ensure an even closure of the product. This design allows you to create three-dimensional buttons. Use paper cubes that are easy to fold yourself. You can also take spare parts from an old real keyboard. Don't forget to decorate the outside of the lid with the manufacturer's "label".

Hello, friends! Today I invite you to plunge back into the world of cardboard toys and figure out how to make a toy computer with your own hands. Children love to copy adults in their games, and such an attribute of everyday adult life as a computer can come in very handy. At the same time, unlike electronic gadgets, a computer made of cardboard does not cause any psychological addictions, but it perfectly contributes to the development of imagination. Complete benefit! 🙂

A realistic cardboard computer can also be useful as a prop for photo shoots or some theatrical productions.

Master class: how to make a toy computer from cardboard

Materials and tools:

Sheets of A4 size office paper (for printing templates); - packaging corrugated cardboard (3 mm thick); - standard (stationery) knife; - metal ruler; - scissors; - double sided tape; - masking tape; - pencil and/or compass; - glue “Moment Crystal”; - glue stick;

A piece of whatman paper.

And, as usual, you will need templates. You can download them here:

Cardboard computer cardboard-comp1.zip

Now we will make a stationary version of the computer, the main element of which is the monitor. Its dimensions are as follows: 40x26.5 cm - external dimensions of the screen, 33 cm - height.

We begin production in the traditional way - first we print out part templates on office paper.

Using a glue stick, glue the halves of templates E-1 and E-2, aligning them along the red line.

We cut out all the templates with small allowances.

STAND

To speed up the process, you can cut out parts 2 pieces at a time by folding the cardboard into 2 layers. But if it is too difficult, then you can cut it in 1 layer, but in this case you will need to print more templates.

So, we fold 2 suitable pieces of corrugated cardboard with their right sides facing each other and fasten them at the edges with pieces of masking tape. Using pieces of double-sided tape, we attach a template of parts P-1 and P-2 to the wrong side of the cardboard, placing it in accordance with the recommended direction of the waves of the corrugated layer of cardboard (i.e., parallel to the lines visible on the wrong side of the cardboard).

Using a stationery knife, cut out the parts along the outer contour.

Advice! Don't try to cut right through. First, use short pressing movements to walk the knife along the contour, then with long movements, rotating the cardboard, walk in a circle several times until it is completely cut through.

After this, we separate one round part and cut out slots in the second part.

Having folded the cardboard in 2 layers, we cut out 2 P-2 parts (they are larger in diameter) with slots using the following template. Then we transfer the template to a new piece of cardboard and cut out one piece P-3 (smaller diameter), also with slots.

We glue all the parts of the stand with Moment Crystal glue, as shown in the photo. It is advisable to combine the pattern of cuts of all the parts - this way the stand will look better.

The stand is ready.

We cut out the parts: S-1 - 1 piece, S-2 - 4 pieces, S-3 - 8 pieces.

For part C-1, only cuts need to be made along the blue lines, without cutting through the very bottom layer (i.e., the front layer of cardboard). Then peel off 2 layers of cardboard in areas around the edges and in the center of the piece.

Glue parts C-2 to part C-1, as shown in the photo.

Let me note right away: single-layer sections are made so that the stand is almost completely wrapped in an outer layer of cardboard. But you don’t have to do this, just cut out 2 additional parts C-2, instead of C-1. Choose the option that you like best.

We glue all the parts of C-3.

And glue the workpiece to parts C-1 + C-2.

We apply glue to part C-3, as well as to the central single-layer section of part C-1. We glue the workpiece.

Glue the remaining single-layer sections.

The stand for the toy monitor is ready.

Part E-1 is cut along the outer contour of the composite template. You need to cut out 4 of these parts. To do this, you can cut out the template exactly along the outer contour and then trace it on cardboard with a pencil.

Or you can use the point of a compass to mark the corners of the part. Then you can cut the sides of the parts using a ruler between these points. Rounded areas of parts can be indicated by several points placed along an arc.

Part E-2 is a frame. It must be cut out in one copy.

Remember to position the templates according to the recommended wave direction of the corrugated cardboard layer. It is not necessary to follow these recommendations exactly, the main thing is that all the parts are oriented the same way. In this case, the sections of the assembled screen and other multilayer parts of the product will look neat.

Using the appropriate template, cut out 1 part E-3 (without slots) and 4 parts E-4 (with slots).

Glue the screen parts together as follows:

All parts of the toy monitor are ready.

The monitor can be easily assembled, and if necessary, disassembled again and stored in a compact form.

If desired, cut out the LG logo from a piece of whatman paper (the template is in the downloaded file) and glue it to the bottom of the screen.

The cardboard monitor is ready! It turned out to be an excellent prop for games in kindergarten (although it can also be useful at home).

Did you like the idea? Enjoy it to your health! :)

Since this is a desktop version of a toy computer, a keyboard may be needed to complete the picture.

We did not make such a keyboard, but templates for it are also provided above.

The manufacturing technology is as follows. We print out a keyboard template (with “wood” buttons or with white buttons) and cut out 2 groups of buttons separately.

We glue double-sided tape to the wrong sides and glue the blanks onto pieces of micro-corrugated cardboard 1.5 mm thick (on the front side).

Ordinary corrugated cardboard 3 mm thick is not suitable here, because the buttons are small and the layers of cardboard can simply fall apart.

Alternatively, you can also use beer/binding cardboard.

We cut out the parts for the base of the OK keyboard from cardboard (2 - 3 pieces), and from paper - a template for installing the buttons.

We glue the parts of the keyboard together and attach a template on top for installing the buttons.

We cut out the buttons along the ruler and glue them to the base of the keyboard.

The photo here shows a laptop keyboard made of cardboard - the principle is the same.

As you can see, the keyboard is somewhat simplified even for a laptop. But we don’t need unnecessary complications. And for children's role-playing games (for example, as businessmen or bosses) it is quite suitable. 🙂

By the way, you can also make this toy laptop with your own hands.

The “trick” is that, thanks to special fasteners, the lid of this laptop opens and closes, just like a real laptop.

And in general it looks very realistic. There are even “sockets” for flash drives and cables, and a touchpad. And you can attach some computer image to the screen (its size is 29.9x11.2 cm) - it will be absolutely beautiful!

You will learn how to make such a laptop from cardboard on the pages of the tenth issue of the Masterklassnitsa electronic magazine. A detailed master class is published there, and templates are presented with which to make a toy computer will not be difficult.

In addition to a laptop made of cardboard, the issue also features other equally interesting and popular toys, as well as jewelry and various accessories that you can make with your own hands, including with your children.

In general, this issue is almost entirely dedicated to children, and most of the master classes are intended specifically for children's creativity. And there are 21 of them in total. Find out what these master classes are about right now in the demo version of the magazine.

Cardboard laptop for children

If your child is over two years old, most likely your laptop has suffered more than once at the hands of a “little explorer.” They fill the computer with liquid, drop it, jump on it and throw tantrums if they try to take the “toy” from the tomboy. We don’t need all this, let’s try to create an alternative version of the computer for kids. The child, at your request, will “create” it with you, and in the future will be able to “work” in it at the dacha, at grandma’s, on a visit or in kindergarten. This laptop can be adapted as a teaching tool.

Let's get started and save our computers.

What do we need

Piece of cardboard

Cardboard cutter or scissors

Black slate paint

Black cardboard or black colored paper pasted onto cardboard, maybe a black marker (for decoration)

Attention!

Black chalkboard paint is sold in many stores, including online stores. Chalkboard paint allows you to get a coating with the effect of a chalkboard (the average price of paint is 700 rubles per jar). A very useful thing, in the future you can make your own chalk board or wall for your child to draw on. This paint can be easily used in children's interiors.

The first thing we need to think about is what size your laptop will be. We will make a small one, 17 by 11 cm. (Based on these proportions, you can come up with your own dimensions for a laptop)

Draw a rectangle on the cardboard and draw a line in the center of this rectangle. Next, we cut out our rectangle from cardboard, and lightly cut the line in the center, but do not cut through it.

Our goal is to weaken the cardboard so that the child can open and close the laptop.

Tape the fold line with transparent tape on the outside of the future laptop.

Cut out three smaller rectangles (for the screen, keyboard and touchpad). We paint the computer “screen” with slate paint; you can also decorate the keyboard with the touchpad, but not necessarily – here we will make do with a simple black marker. Let the slate paint dry (30 minutes will be enough). After the “screen” has dried, glue all the parts in place.

Lorena Kormiteleva

I present to your attention master-class from Lorena Eduardovna Kormiteleva creating a children's laptop.

For this you will need:

1. Candy box (I have Mercy)

2. Dish sponge 2-3 pcs.

3. Letter stickers

5. Scissors

6. Glue gun

7. Wide double-sided tape

I've wanted it for a long time make a laptop for children, but there was no suitable box, half a year later it appeared and I immediately started working.

I bought the stickers from children's store.

Since the children had already played with the box, they had to glue it with wide double-sided tape.

Then I started working on the keyboard. I tried on the letters (check if everything fits) I prepared some cardboard and a sponge cut into squares and started cutting. Glue the letter onto the cardboard, then glue it to the sponge with a gun. Letters, numbers, signs, pictures.

The outer side was covered with a cloth using a glue gun and double-sided tape.

I made the screen from white cardboard. I thought for a long time about what to depict on my desktop.

I divided the remaining pictures into subgroups: domestic and wild animals. First, I outlined the forest and the farm with a simple pencil, then I pasted pictures and colored them with colored pencils and felt-tip pens.

The laptop is ready for gaming.
