When the sun shines mercilessly outside the window, a breath of fresh wind seems like the highest pleasure. If it were colored, then not a single stream of it would go unnoticed: I saw a colorful air wave, stood in its path, raised my hands and... here it is - the bliss of “swimming” in the refreshing surf.
Yes, it is not easy to see the wind, but it is easy to detect its presence. How? Let's do this.
Preparatory stage
The pinwheel is a wonderful wind catcher. Children especially like this toy. How to make a pinwheel? From paper, of course. For beginners and children, colored paper is an ideal material that is easy to work with.
Check if you have everything you need at hand:
Square sheet of paper;
Scissors;
A small nail and two beads (or a pin, a button on a round stem, etc.);
A skewer (or pencil, cocktail straw, wooden stick, etc.).
Stage 1
Now let’s take a closer look at the question of how to make a pinwheel out of paper.
Place the beautiful piece of paper you have chosen on the table directly in front of you. Bend it exactly diagonally in half. Unbend. Fold again on the other side. Flatten the square. The sheet should form two lines intersecting in the center, obtained by folding.
Make four cuts along the fold from each corner to the center. But do not cut to the intersection, leave one and a half centimeters to the “meeting point” of the two lines.
Stage 2
Use a nail to make preliminary punctures: in the center (just where the lines intersect) and one hole in each left corner of the triangle. This is what you should get:
Stage 3
Place the bead on the stud.
Stage 4
Let's proceed to the final stage of the process called "How to make a pinwheel out of paper." Connect all four ends to the holes in the center and thread a nail through each of them, as well as through the middle. On the back side, where the point now sticks out, put a second bead on it.
Level 5
Attach the pinwheel “inflorescence” to a wooden stick.
The toy is ready! Now even your child can explain from paper. Stick a stick into a flower pot, and it will not only “bloom,” but also act as a stand as a reliable assistant guarding the breath of a fresh breeze.
By the way, this simple thing can become stylish element room design. An elegant pinwheel will decorate the office.

IN modern world All more money have to pay for utilities, the list of which includes the supply of electricity. Therefore, owners of private houses are increasingly thinking about how to make a 220V wind generator with their own hands, which can provide uninterrupted electricity to the entire house.
Industrial wind generator
All wind turbines consist of a blade, turbine rotor, generator, generator axle, inverter and battery. All models can be roughly divided into industrial and home, but their operating principles will be the same.
Rotating, the rotor creates alternating current with three phases, which goes through the controller to the battery, and then, in the inverter, it is converted into stable current for supply to electrical appliances.
The rotation of the blades occurs due to physical action using an impulse or lifting force, as a result of which the flywheel comes into action, as well as under the influence of a braking force. In the process, the flywheel begins to spin, and the rotor creates a magnetic field on the fixed part of the generator, after which the current is reproduced.
In general, wind generators are divided into vertical and horizontal. Which has to do with the location of the axis of rotation.
Vertical option
When planning to create a 220V windmill with your own hands, first of all think about the vertical options. Among them are:
- Savonius rotor. The simplest one, which appeared back in 1924. It is based on two half-cylinders on a vertical axis. Disadvantages include low use of wind energy.
- With Daria rotor. Appeared in 1931, spinning occurs due to the difference in resistance between the aerodynamic hump and the tape pocket, so the disadvantages include low torque, as well as the need to mount an odd number of blades.
Variety wind generator Daria - The blades have a twisted shape, reducing the load on the bearing and increasing service life. The disadvantage is the high price.
A homemade option will be cheaper if it is properly thought out and installed.

RCD: what is it? Have you ever heard the abbreviation RCD? You will find out what it is by reading the review to the end. Briefly, I would like to add that this device can protect housing and all its inhabitants from emergency situations related to electricity.
Horizontal models
Horizontal models are divided by the number of blades. They have higher efficiency, but there is a need to install a weather vane to constantly search for the direction of the wind. All models have high rotation speeds; instead of blades, a counterweight is mounted, which affects air resistance.
Multi-blade models can have up to 50 blades with high inertia. They can be used to operate water pumps.
How to make a 220V wind generator with your own hands
To provide a private house a constant flow of electricity at an average wind speed of 4 m/s is sufficient:
- 0.15-0.2 kW, which is used for basic needs;
- 1-5 kW for electrical equipment;
- 20 kW for the whole house with heating.
It is worth considering that the wind does not always blow, so you should provide a DIY windmill for your home with a battery with a charge controller, as well as an inverter to which the devices are connected.
For any model of a homemade windmill you will need the following basic elements:
- rotor - the part that rotates from the wind;
- blades, usually they are mounted from wood or light metal;
- a generator that will convert wind power into electricity;
- tail, which helps determine the direction of air flow (for the horizontal version);
- horizontal yard to hold the generator, tail and turbine;
- match;
- connecting wire and shield.
The shield will include a battery, controller and inverter. Let's look at two options for how to build a wind generator with your own hands.

Features of assembling a wind generator from a washing machine with your own hands
Let's look at how to make a 220V wind generator with your own hands using an old-style engine.
Table 1. detailed instructions wind generator from washing machine with photo
| What to do | Photo example |
|---|---|
| You should buy neodymium magnets that are mounted in recesses on the engine rotor. The notches themselves are made on lathe, For correct placement use the diagram. |  |
| The magnets must be glued with superglue into the prepared recesses. Then, they should be wrapped in paper, and the rest of the space should be filled with epoxy. |  |
| Next, we prepare the axle, which is best ordered from a turner. Inside the hollow structure there should be room for the cable and a hole for its entry. We mount the holder from an iron rod. For it we use a grinder, with which we cut off two tubes (you attach the generator to them), and weld them at the other end. |  |
| Let's move on to the blades, which can be made from a 16 cm pipe for external sewerage. IN in this case use a jigsaw. |  |
| All that remains is to assemble the wind generator, securing all the elements. To begin with, we attach the generator, blades, rotor and tail to the support rail. Don't forget to cover the generator with a casing. |  |
| The power plant should be secured using a hinge mechanism, and the mast should be mounted in concrete base for 4 bolts. |  |
| Route the wire to the distribution panel. |  |
| Connect all elements and perform performance testing. |  |

Features of assembling a vertical wind generator from a car generator with your own hands
When “homemade” people think about how to make 220V wind generators with their own hands, they most often use car generators as a basis. It is not difficult to assemble, but for work you will need:
- 12V generator from the car;
- battery;
- converter from 12 to 220 W with a power of 1.2 kW;
- aluminum or steel barrel or bucket for blades;
- car warning light;
- switch;
- voltmeter;
- copper wires with a cross-section of more than 2 mm;
- clamp for fastening.
To assemble a vertical wind generator with your own hands, you will need a tape measure and a pencil, a set of keys, an electric drill and a grinder, as well as metal scissors. Detailed installation instructions are given below.

| Action | Image |
|---|---|
| The prepared metal container must be marked and cut into 4 equal parts, but this must not be done completely. Drill holes for bolts in each part, which should be symmetrical. |  |
| Blades that are not completely cut are slightly bent; the speed of rotation directly depends on this process, so decide in advance in which direction the equipment should rotate. |  |
| It is necessary to secure the blades to the pulley, and install the generator on the mast using clamps, and also assemble the wiring according to the prepared diagram. |  |
| The main thing is to correctly connect the wires to which the battery is connected in the panel, as well as the converter. |  |

In the process of creating this wonderful windmill, you will see that it is made so simply and easily that it’s even hard to believe! You might even want to make 10 of these windmills. Give it a try.
Wind turbines are relevant at any time of the year. The main thing is that it is windy outside. Such toys can be used for playing, or they can be placed on the balcony as decoration.
So, what will you need:
- bright paper (preferably with patterns or polka dots)
- pencils with an eraser at the end
- stationery knife
- ruler
- hairpins with multi-colored ends
- strong glue (hot glue is better)
Let's start doing
To start, take colored paper and make an even square out of it. You can adjust the size yourself.
Now mark the center of the sheet with a cross (do everything under the ruler with a simple pencil). Leaving a small square around the cross, draw lines as in the photo below. We will cut along these lines and it is important that the small area around the cross remains untouched. Be sure to put dots near the lines (as in the photo below).
Now we make cuts along the marked lines (don’t forget about the center of the sheet, we don’t cut it).
Now we wrap the corners of the square towards the center (as in the photo below).
Now, perhaps, will be the most difficult part of the work. It is necessary to place this sheet on a pencil, pin off the curved ends with a pin and then place the same pin on the eraser of the pencil.
Now apply a bead of hot glue (or silicone glue) to secure the pin. This will also serve as protection for children so that they do not prick their fingers.
OK it's all over Now! The windmill is ready. Enjoy!
greetings to all brain friends! And I share with you brain guidance about the creation crafts-windmill, clearly showing the conversion of mechanical energy into electrical energy.
Having collected this simple homemade and having understood the principle of operation, it is possible in the future to make a larger-scale and actually operating wind generator. And a simple windmill will delight you by lighting up your yard!
Step 1: Materials
- marker
- motor
- LED (mine is red)
- plastic or wooden plate
- PVC tee 3/4 - 1/2 - 1/2
- connector 1/2
- glue gun
- drill with bit for drilling
- blades
- flange 1/2
- pvc pipe scissors
- punch or awl
- sealing ring
- roulette
- 30cm PVC pipes 1/2
- and of course, the wind :)
In count necessary materials It may seem that the craft is complicated, but it is not. The motor can be taken from an old VCR or DVD, the blades can be easily made from spoons and a bottle cap. PVC pipes can be cut perfectly with a regular hacksaw, and not just with special pipe scissors.
Step 2: Cutting the Pipe
Mark on brain tube segments of 2.5 and 12.5 cm, and then cut them off with scissors. This will result in three segments of 5, 12.5 and 15 cm.
Step 3: Marking the Hole
We put an o-ring on the front side of the motor, apply it to the tee and mark a hole for the LED, it will be located near the back of the motor.
Step 4: Drilling the Hole
Shilom or brainkerner We mark the center of the hole, so the drill will not slip, and drill a hole of such a diameter that you can easily install an LED in it.
Step 5: LED Mounting
We take the LED and determine the polarity of its contacts: the long leg of the LED is the positive contact, and then we connect the LED to the motor. The positive contact is to the “plus” of the motor, the negative contact, respectively, to the “minus”. We secure the LED legs by bending the motor contacts.
Step 6: Check functionality
We install the blades on the axis of the motor and blow on under the tree, strong enough for the LED to light up.
Step 7: Installing the Motor
Carefully bend the LED and insert it brain motor into the hole of the tee until it fits tightly, then insert the LED into the intended hole and straighten it.
Step 8: Fixing the Motor
By using glue gun fix the motor in the tee.
Step 9: Refinement of the connector
We put the tee with the motor aside and take the connector. Unscrew the connector and remove the O-ring that is located inside, this will allow the windmill to homemade rotate freely.
Step 10: Bushing Assembly
We insert the previously cut piece of 2.5cm tube into the connector, thereby obtaining something like a sleeve.
Step 11: Installing the Tee
We mount a tee with a motor on the bushing.
Step 12: Shank
As a “shank”, we tightly insert a piece into the tee braintubes 15cm, and insert a 12.5cm segment as a “stand”.
Step 13: Finishing the Shank
Using hot glue, attach the plate to the shank.
Step 14: The homemade product is ready!
We tighten or loosen the connector parts depending on your needs, mount the flange on the stand and glue all the fixed parts together. If desired, we paint the windmill and that’s it, brain trick ready!
Thank you for your attention, I hope this homemade worthy of being a visual aid!
The wind spinner has long been one of the favorite pastimes of children of all ages. Even a small breath of wind spins the multi-colored pinwheel, and the child watches its rotation with great interest.
A toy that a child makes with his own hands will always be more valuable to him than one that he got for nothing. After all, he can proudly boast that he made this toy himself. Moreover, doing needlework is very useful, because it develops fine motor skills hands and therefore paper crafts or, for example, light bulb crafts are an excellent chance to improve a child’s skills, as well as for his development. You will probably think that making a toy like a wind spinner is not at all easy. Nothing like that, everything is much simpler than you think!
In order to make a wind spinner we will need: a pin with a head, a set of colored paper, scissors, a stick and a pencil.
The first thing to do is take two sheets of colored paper and cut out a square from each. Most optimal size sides take 20 centimeters. Then you will need to find the center of the square. To do this, draw two diagonals and at their intersection you will find the center of the square. Then step back 1 centimeter from the center of the square in each direction and mark these indentations.
Then take scissors and cut the square along all four lines to the marks.
Afterwards, using a pin, you need to pierce a hole in the center, as well as in the left corner of each resulting part. It is necessary for the pinwheel to spin easily and freely, which is why you need to make a hole slightly wider than the needle itself.
Then try to do a similar procedure with another sheet of colored paper, and only after this operation can you safely fold both squares together.
Fold the left corner of each square toward the center, so that the hole in the corner of each side coincides with the hole in the center.
Then secure this entire structure with a nail or button to a wooden stick.
On average, making such a wind turbine takes no more than five minutes. Imagine how much joy your child will get from the work done with you.
