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:

Now we will make a stationary version of the computer, the main element of which is the monitor. Its dimensions are as follows: 40×26.5 cm— external dimensions of the screen, 33 cm- height.

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

Using a glue stick, glue the halves of the templates together E-1 And E-2, combining 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 heavy, then you can cut it in 1 layer, just in this case you will need to print it 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. We attach the parts template to the wrong side of the cardboard using pieces of double-sided tape. P-1 And P-2, positioning 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, cut out 2 parts according to the following template P-2(they are larger in diameter) with slots. Then we transfer the template to a new piece of cardboard and cut out one part 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.

RACK

Cutting out the details: S-1- 1 PC., S-2- 4 things., S-3- 8 pcs.

At the detail S-1 along the lines of blue color You only need to make cuts 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.

Gluing the parts S-2 to detail S-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 S-2, instead of S-1. Choose the option that you like best.

Glue all the parts together S-3.

And glue the blank to the parts S-1 + S-2.

Apply glue to the part S-3, as well as on the central single-layer section of the part S-1. We glue the workpiece.

Glue the remaining single-layer sections.

The stand for the toy monitor is ready.

SCREEN

Detail E-1 cut along the outer contour of the composite template. It is necessary to cut out 4 such 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.

Detail E-2- this 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:

ASSEMBLY

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 playing games. kindergarten(although it may 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.

Cut out the parts for the keyboard base from cardboard OK(2 - 3 pcs.), and from paper - a template for installing buttons.

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

Cut out the buttons using a 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 role playing games(for example, 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 to the screen (its size 29.9×11.2 cm) you can attach some computer image - 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. Published there detailed master class, and templates are presented with which making 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.

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

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.

If you take a piece of paper, a pen, a printer, scissors and glue... 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 "perform" 10 various instructions(with codes from 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, I “typed” (that is, wrote with a pencil into memory cells 17 through 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 Explanation

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)

Making a personal computer for a child with your own hands

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

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.

The computer is ready. Now your child will be able to carry it with him everywhere, and also write something new with crayons every day (provided that you used chalkboard-effect paint).

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 with a simple pencil forest, farming, then glued the pictures and colored them with colored pencils and felt-tip pens.

The laptop is ready for gaming.
