The weather is getting warmer outside, it's time to think about ventilation. In this episode Roman Ursu will do bladeless fan. You can easily repeat this product with your own hands. Four pieces of cardboard are used in the product. The width must match the width of the cooler. 120 mm. A switch and power connector are built into the housing. Let's take the dimensions and make a hole according to the required diameter. You will also need a 12-volt power supply for a cooler that consumes 0.25 m. The unit is 2 amperes, so that’s enough. The top of the Dyson fan is cylindrical in shape. This means that we draw two circles with a diameter of 15 cm. One of them is 11 cm, the other is 12 cm. To ensure that the parts stick well to the base, we take one of the walls, apply the parts, draw a line and cut them off. Now, to form the cylinders, you will need three segments with the following dimensions: 12 x 74, 12 x 82, 15 x 86 cm. We will figure out what and where to glue at the assembly stage. Let's make cuts in each wall. These will be the air channels. They look like nice legs.

Let's start assembling a beautiful bladeless fan, placing the courier in the middle. We glue each wall one by one. The wires can be removed as shown in the video. It would be nice to figure out the connection. We use a switch, so we separate one of the wires and form a circuit. The wires go to the power connector, black to minus, red to plus.

You need to connect all the previously prepared parts with your own hands. Take a ring with an internal diameter of 11 cm. It will be in front. And the segment is 12x74. We connect as in the video.

We repeat the same with the second ring and the 12 x 82 blank. To keep the rings fixed and stable, we use five small strength partitions. The length is just under 12 cm. All that remains is to close the structure.

We use the last piece of 15 x 86 cm.

Finally, we make it beautiful, remove excess glue, and cover it with paint. In general, the bladeless fan is ready.

There's a lot ahead useful homemade products, we are waiting for the warm sun to take pictures next video and show it on the channel.

A USB cooler is a very ordinary fan, however, smaller in size, which connects to the corresponding connector on the computer. You can purchase a ready-made device or make it yourself, which is quite simple; the most important thing is to strictly follow the instructions.

How to make a fan

It is worth noting that this kind of technique is not considered particularly powerful, however, practice and numerous positive reviews convince us otherwise. Like any other device, such a fan has certain pros and cons.

The main advantages include the fact that:

• It is compact;
• Multifunctional:
• It's easy to use;
• You can make it yourself.

Among the main types of such fans you can find desktop and compact models. Desktop options They cope well with their main task and can efficiently cool computer parts even if it is used for a long time. USB mini fans are distinguished by their compact size. Their design can be absolutely anything, and in terms of power they are somewhat inferior to desktop models. Compact options are intended only for light cooling of equipment, and desktop models are intended for high-quality cooling of the room and the space around the computer.

This type of equipment has very few disadvantages, however, if a person does not have even the slightest idea about the operation of equipment and electronics, then he does not even need to try to make a fan at home.

In addition, it is worth considering that mini-models cannot regulate the direction of the air flow, and in order to solve this problem, you will have to put in a lot of effort. Working at a computer in summer time, many people suffer from extreme heat, even if there is an air conditioner, since it is not always convenient to turn it on.

To solve this problem, you can make a small fan out of:

• Cooler;
• Motor;
• Small engine.

A homemade fan can also be connected to a car using a USB cable. Such homemade products can be very useful and can be made from unnecessary parts.

Initially, you need to take the old cooler and prepare it. It has two wires: black and red. Approximately 10 mm of insulation must be removed from each wire.

Important! How larger size cooler, the greater the wind flow will result.

You also need to prepare the USB wire by stripping the insulation on it. The result should be 2 red and 2 black wires. Then connect these wires to each other, taking into account the color marking. Everything is well insulated. It is worth remembering that the more insulation, the better. Then attach to the received device additional elements, which will act as a means for greater cooling or simply decoration. For convenience, you can install the finished cooler in a shoebox to make it more stable and connect the wire to the computer. You can also make a fan using a motor from a toy or an engine as a base. This will allow for better room cooling.

There are many options self-made a fan that will work no worse than a purchased product.

A homemade fan can be made from:

• Disk;
• Thick paper;
• Plastic bottle.

It's very easy to make a small fan out of ordinary ones. computer disks. It can be used to cool a computer or laptop, as well as a user who spends a lot of time working with technology.

To do this, you initially need to prepare such materials as:

• CDs;
• Motor;
• Wine cork;
• USB cable with plug;
• Cardboard.

The motor can be taken from an old toy, for example, a toy car. The assembly process is quite simple. To do this, you need to take one disk and use a marker to divide it into 8 identical parts. Then draw a soldering iron along these lines from the transparent part to the edge and cut with a knife heated on the stove.

Lightly heat the surface of the disk over the flame of a burning candle so that the blades can be slightly expanded. Insert into the hole wine cork, fix and process the edges with hot glue.

Connect the USB cable to the motor. Make a tube out of cardboard, to which you glue the motor, as well as another whole disk, which will act as a stand. When everything is ready, attach the propeller to the motor shaft and fan rod. Secure it with hot glue. Despite the fact that the process of making it takes a lot of time, however, the result will definitely please you. The disc blades will rotate, resulting in good cooling. If necessary, you can install a mini flash drive and connect the watch. You can also make a battery-powered fan or power it by connecting a generator. It all depends on your own preferences and knowledge of technology and electronics. Such crafts are quite easy to implement; the most important thing is to do everything step by step and strictly follow the instructions.

Simple DIY fan

You can make your own quite original and stylish paper ceiling fan. This bladeless model is somewhat similar in appearance to a snail, which attracts buyers. However, it works very well and can be easily made by yourself. The principle of operation of such a fan is quite simple, since at the base of the device there is a small turbine that helps create air flows passing through the side openings.

To create such a device you will need:

• Computer cooler;
• Old computer case with power and USB connector;
• Switch;
• Thick paper;
• Hot glue gun.

First you need to make the base of the device. For this, thick cardboard or paper is used. The parameters must be taken into account based on the size of the cooler. Integrate a switch and power connector into the housing.

Then cut out two circles from paper that will act as the main part of the fan. They are attached to the body of the product. Assemble the device, fastening all parts with hot glue so that the cooler is located in the central part of the case. Place the wires in a corner of the structure. Then connect the switch and make a test connection to the network. If everything works, you need to attach parts cut out of paper to the body to make the device safe. Thus, the impeller will be located inside the device itself, which is completely safe during its operation. In addition, you can make a hood in almost the same way, however, you should use a powerful working compressor.

Methods: how to connect a cooler to USB

You can quite simply connect the cooler to the USB and you don’t need any specific knowledge or skills to do this.

This will require:

• Computer cooler;
• USB cable;
• Insulating tape.

Initially, you need to carefully strip the wires on the cooler and the USB cable by about 1 cm each. Connect them together by color and if you have a soldering iron, then it’s best to solder them. Then you need to wind the electrical tape so as to completely insulate the wires, otherwise it may burn out. USB port when closing contacts. After this, check the functionality of the cooler. In just a few minutes you can get a very good coolant.

How to make a fan with your own hands (video)

Making a fan yourself is not at all difficult. The most important thing is to choose the right materials and components, and also carry out all the steps step by step.

Throughout the long winter, we look forward to pleasant summer days, and with the onset of hot weather, for some reason we begin to dream of coolness. How delightfully a light breeze created by a small homemade fan will help restore strength and relieve fatigue. Plus, making it is incredibly fun, right?

We invite you to familiarize yourself with step by step instructions on assembling the simplest effective devices from literally waste raw materials. The article presented to your attention describes in detail how to make a fan with your own hands and what a home craftsman will need for this.

At your disposal detailed description manufacturing options whose effects have been tested in practice. You can make such devices yourself without having any experience at all. For a complete understanding of the information, attached step by step photos and video instructions.

The simplest fan can be made from CD discs. It can be used, for example, to locally influence a user who for a long time spends time at the computer.

Let's prepare the starting materials to complete the work:

• CD discs – 2 pcs.;
• low-power motor;
• wine bottle cork;
• cable with USB plug;
• a tube or rectangle made of thick cardboard;
• soldering iron;
• candle or lighter, hot glue;
• pencil, ruler, squared paper.

For our purposes, you can use a motor from an old toy, for example, from a toy car. A toilet paper roll slightly decorated with decorative finishing paper can be used as a cardboard tube.

The main advantage of this model is that almost any do-it-yourself enthusiast will have all the materials necessary for its manufacture.

The assembly process of the mini fan is quite simple.

Let's take one of the CDs and use a marker to divide its surface into eight identical sections. The easiest way to do this is to use a sheet of checkered paper.

Draw a cross on it from a horizontal and vertical line. We divide each of the four resulting right angles in half. Using cells, this is not difficult to do.

Using a very simple method using a checkered piece of paper, we can achieve the perfect layout of the disk into eight equal sectors

We place a disk on our drawing so that the intersecting lines are in the very center of its hole. Alternately applying a ruler to the lines diverging from the center, we make markings on the disk. This way the sections will be the same.

To divide the disk into blades, follow the marking lines with a soldering iron from the transparent part to the edge.

You can also use scissors for cutting, but there is a danger that the workpiece will crack during the process. If you don’t have a soldering iron, you need to use a knife preheated on the stove. When working with a soldering iron, deposited plastic is formed along the edges of the cut, which can be easily removed with a knife.

Cutting a disk with a soldering iron is the most effective method, in which the workpiece will not crack or deform, and the remnants of the deposited plastic can be easily removed with a knife

We heat the surface of the disk over the flame of a burning candle so that the blades can be slightly turned. If you don't have a candle, a lighter or a soldering iron will do.

The central part of the disk should be heated, and all blades should be turned in the same direction. A wine cork is placed in the hole of the disc. To fix it better, you need to pre-treat the edges of the hole with hot glue.

The USB cable must be connected to the motor. If we don’t guess the direction of rotation of the propeller, we can swap the reins, that is, change the polarity.

The motor needs to be glued to a cardboard tube, and the tube itself to a second CD, which will act as the base of the stand.

When the plug is installed in the hole, the stand from the second CD and cardboard tube, as well as the connecting device are already assembled, it is very important to correctly fit the propeller onto the motor shaft

Now the propeller needs to be “planted” on the rod of the future fan. We will try to make sure that it is installed strictly in the center. You can secure it in this position using hot glue.

After all work is completed, the fan is ready for use.

Although the construction of this device will not take you much time, the result of the work performed will undoubtedly please you

How to make something similar, but a little more complex design Having included a regulator in the circuit, look at the video posted at the end of this article.

Do you find these homemade instructions complicated? Then you may be interested in information about and rules for choosing them in order to purchase a ready-made device offered by household appliance manufacturers.

Fan based on a plastic bottle

What our craftsmen don’t do from plastic bottles! The time has come to say that they also make a very good fan. It may not ventilate your entire room, but it will definitely help those who have to work at a computer.

We offer two options for creating such a fan model.

Option #1 – hard plastic model

To complete the work we will need:

• plastic bottle with a capacity of 1.5 liters;
• a motor from an old toy;
• small switch;
• Duracell battery;
• marker;
• scissors;
• candle;
• hammer and nail;
• foam;
• hot glue gun.

So, let's take the ordinary one plastic bottle 1.5 liters with plug. At the level of the label line, cut it off top part. This is exactly what we need to make the propeller. Dividing the surface plastic blank into six parts.

We try to mark it out so that we get equal sectors: the quality of operation of the future device depends on this.

We cut the workpiece along the markings almost to the neck. We bend the blades of the future propeller and cut off every second of them. We are left with a blank with three blades equidistant from each other. The edges of each blade must be rounded. We do this carefully.

To remove those parts of the blades that are closer to the neck of the workpiece, it is better to use a utility knife; do not forget to round the edges of the blades

Now we will need a small candle. Let's light it up. We heat each blade at the base on it to turn it in the direction we need. All blades must be turned in the same direction. Remove the lid from the workpiece and punch a hole in the very center using a nail and hammer.

We place the plug on the rod of a small motor. Such motors can remain from old children's toys. As a rule, getting them is not difficult. Secure the cork with glue.

Now you need to make a base on which the motor will rest. For this purpose, we take, for example, a piece of polystyrene foam. We attach a rectangle to it, which can also be cut out of foam packaging.

Our motor, to which the propeller is attached, will be fixed on the upper surface of this rectangle. To do this, you need to make a recess in the foam that corresponds to the parameters of the motor.

Hot melt adhesive is used to secure the elements of the product. If it is unavailable, other adhesives can be used. It is important that the fastening itself is as reliable as possible.

We made parts designed to enhance airflow. They will provide accelerated cooling of the space around.

Now you need to make the basis for fixing them:

After preparing the device designed to enhance the fan’s performance, we proceed to assembly and commissioning:

Stylish product without blades

We are accustomed to the fact that the main part of the fan is the propeller. This design part rotates, creating the necessary air flow.

But there are also. They have become fashionable, primarily due to their safety for younger family members and pets. In addition, these products look stylish: they can fit into any interior and decorate it.

The finished bladeless fan is completely different from the device we are used to seeing, however, it works great

Like most other things that serve a person, a bladeless fan can also be made with your own hands.

The principle of its operation is simple: at the base of the device there is a small turbine, which allows you to create air flows passing through the side openings.

For work we will need:

• computer cooler;
• power supply unit and connector;
• small switch;
• hot glue gun;
• cardboard or thick paper;
• scissors, pencil, ruler, compass and caliper.

In principle, we need a caliper solely in order not to make a mistake in the dimensions of the product. If it is not available, then you can get by with a regular ruler, tape measure or measuring tape.

Let's get to work.

First, let's make the body - the base of the product. To do this, cut out four rectangular pieces of cardboard. To determine the parameters of the base, measure the width of the cooler. The resulting size will match the width of the rectangles.

For convenience, we will operate with specific sizes. The width of our cooler is 120 mm. This means that the width of the rectangle is also 120 mm.

A small switch and power connector will be built into the body of our product. In order for them to stay tight enough in the future, you need to take measurements from them.

The holes in the housing must correspond to the obtained values. You need to make holes until the rectangles become part of the body: cutting them out in flat objects is always easier.

We need a twelve-volt power supply and a corresponding cooler that consumes only 0.25A. Taking into account the fact that we have a 2A block, we can assume that we are quite well prepared for further exploitation future device.

Now we take sheets of cardboard from which we have to cut out the elements of the main part of the fan. First, let's draw two circles. The radius of each of them is 15 cm. Cut out both circles.

In one of them, let's call it A, we will draw an inner circle with a radius of 11 cm. In the second, which we will call B, the radius of the inner circle will be 12 cm. Carefully cut out the inner circles. We received rings A and B.

The resulting rings will be attached to the body of the product. In order for them to better adhere to the surface of the body, we will apply one of the rectangular blanks to each of the rings and cut off a segment, the flat side of which corresponds to the width of the rectangle.

In order to reliably glue the rings to the base on which they will be installed, it is necessary to ensure the maximum contact area: for this purpose, a sector is cut off at the bottom of the product

The main part of a bladeless fan is cylindrical in shape. To make it, we need strips of cardboard with the following parameters: the first - 12x74cm, the second - 12x82cm, the third -15x86cm. During the assembly process it will become clear what to do with each of these three strips.

Before assembling the body, cut a notch in the bottom of each rectangle. This way we not only make legs for the future fan, but also create channels for incoming air.

Recesses in the lower part of the base can be made and rectangular shape, but it’s better to add an arc to the original rectangle by drawing it using a CD

We will assemble the body using hot melt glue. The cooler should be located approximately in the central part of the case, surrounded by four rectangles that form the walls of the structure. Lubricate the cooler around the perimeter with glue and surround it with walls.

Don't forget that the notches in the walls that we just cut should be at the bottom of the case.

The wires from the cooler can be tucked into a corner of the structure, securing them in this position with glue.

At this stage it is best to mount and connect. Since we are using a switch, we need to split one of the wires and form a circuit.

The wires should be connected to the power connector (red - positive, black - negative). If we get the polarity wrong, we just need to swap the wires. Using hot glue, we secure the connector and switch in the places intended for them.

We connect the power and check if the turbine is working. If everything is in order, we continue assembling our bladeless model.

Take ring A, which will be located in the front of the device, and the first strip (12x74cm). We close the strip into a circle and glue it into the inner circumference of ring A. The result is something like a cylinder hat without a top, but with a brim. The same must be done with ring B and the second strip (12x82cm).

This kind of hat came out of ring A and the first strip that we glued along the inner circumference of the ring

We glue the first “cylinder” to the front side of the body in the place where we cut off the segment. We also glue the second “cylinder” to the back side of the body with a cut surface. In this case, the smaller “cylinder” ends up inside the larger one.

The stability of the structure can be imparted using five strength partitions, fixed between the rings using the same glue. They need to be cut out of cardboard. The length of the partitions should be slightly less than 12cm.

Now lateral surface the main structure should be covered with the remaining third strip of cardboard (15x86cm).

This photo shows the internal structure of the fan quite clearly, which will be hidden from us by the last (third) strip

In principle, the fan is ready. All that remains is to give it an external gloss. To do this, remove excess glue and cover its outer surfaces with paint or decorative paper.

So that you can see how correctly you understood and did everything, watch the video dedicated to self-creation bladeless fan, which we have placed at the end of this article.

If you are interested in assembling interesting and useful devices, then you may be interested in information about making an air conditioner at home, discussed in our other article

The green plastic fan that the video is dedicated to not only works well, but also looks great.

It will become a real desktop decoration for your workplace:

The peculiarity of the bladeless fan, which you can easily assemble following the instructions and video, is that the air flow appears as if from nowhere. The model attracts with its originality.

Spend some time on her decorative design, and you will see how flawlessly it will fit into your interior:

We have presented you with the best homemade fan models. And they are the best because their construction does not require special mechanisms, complex tools, expensive materials or special skills. Absolutely anyone can create them. home handyman, even a beginner.

We hope that the success you will definitely achieve by making a fan will awaken your taste for independent creativity.

Do you use a homemade fan made from scrap materials? Or did you use one of the instructions given in our article when assembling the device? Perhaps you have improved the equipment you have in your home? Tell us about your experience - leave your comments.

Creating high-density airflow is possible in several ways. One of the effective ones is a radial type fan or “snail”. It differs from others not only in shape, but also in its operating principle.

Fan device and design

Sometimes an impeller and a power unit are not enough to move air. In conditions of limited space should be used special kind designs exhaust equipment. It has a spiral-shaped body that acts as an air channel. You can make it yourself or purchase it already finished model.

To form the flow, the design includes a radial impeller. It connects to the power unit. The wheel blades have a curved shape and create a discharged area when moving. Air (or gas) enters it from the inlet pipe. When moving along the spiral body, the speed at the outlet increases.

Depending on the application centrifugal fan snail maybe general purpose, heat-resistant or corrosion-resistant. It is also necessary to take into account the amount of air flow created:

• low pressure. Scope of application: production workshops, household appliances. The air temperature should not exceed +80°C. Mandatory absence of aggressive environments;
• average pressure value. It is part of exhaust equipment for removing or transporting small fraction materials, sawdust, grain;
• high pressure. Forms an air flow into the fuel combustion zone. Installed in many types of boilers.

The direction of movement of the blades is determined by the design, and, in particular, by the location of the outlet pipe. If it is located on the left side, the rotor should rotate clockwise. The number of blades and their curvature are also taken into account.

For powerful models you need to do it yourself solid foundation with housing fixation. The industrial installation will vibrate strongly, which may lead to its gradual destruction.

Self-production

First of all, you need to decide functional purpose centrifugal fan. If it is necessary for ventilation of a certain part of the room or equipment, the housing can be made from scrap materials. To complete the boiler, you will need to use heat-resistant steel or make it from stainless steel sheets yourself.

First, the power is calculated and the set of components is determined. The best option the snail will be dismantled from old equipment - an extractor hood or a vacuum cleaner. The advantage of this manufacturing method is the exact match between the power of the power unit and the body parameters. A snail fan can be easily made with your own hands only for some applied purposes in a small home workshop. In other cases, it is recommended to purchase a ready-made model industrial type or take the old one from the car.

Procedure to make a centrifugal fan with your own hands.

1. Calculation overall dimensions. If the device will be installed in a confined space, special damper pads are provided to compensate for vibration.
2. Manufacturing of the body. In the absence of finished design You can use plastic sheets, steel or plywood. In the latter case special attention is given to sealing joints.
3. Installation diagram of the power unit. It rotates the blades, so you need to choose the type of drive. For small structures a shaft is used that connects the motor gearbox to the rotor. In powerful installations, a belt type drive is used.
4. Fastening elements. If the fan is installed on the outer casing of, for example, a boiler, mounting U-shaped plates are made. With significant power, it will be necessary to make a reliable and massive base.

This general scheme, according to which you can make a functional exhaust centrifugal unit with your own hands. It may change depending on the availability of components. It is important to comply with the housing sealing requirements, as well as ensure reliable protection power unit from possible clogging with dust and debris.

The fan will make a lot of noise during operation. Reducing this will be problematic, since vibration of the housing during the movement of air flows is almost impossible to compensate with your own hands. This is especially true for models made of metal and plastic. Wood can partially reduce background noise, but at the same time it has a short service life.

In the video you can see the process of manufacturing a case from PVC sheets:

Review and comparison of production ready models

Considering radial fan snail, it is necessary to take into account the material of manufacture: cast aluminum body, sheet or stainless steel. A model is selected based on specific needs; consider an example of serial models in a cast case.

When working at a computer in the summer, or just on vacation, sometimes you want a gentle breeze, “local” coolness. The air flow of an office air conditioner doesn't create the sweet comfort of a gentle, directional blast that a mini fan provides. It is very easy to make such a device with your own hands.

How to make a “personal breeze”

The most famous invention in this area since ancient times is folding fans. They were made from painted paper and ostrich feathers, painted silk and carved bamboo sticks. This device has only one drawback: to obtain the much-desired coolness, you need to hold it in your hand, which is not always convenient. It’s funny to imagine a manager or economist working at a computer and fanning himself.

Therefore, let’s return to our topic and figure out how to provide yourself with a pleasant breeze in the heat. To make a mini-fan with your own hands, you need to solve the following several problems:

1. What kind of rotating propeller will it be, and what material will it be made of?
2. Where can I get a motor?
3. What power source will the device operate from?
4. Is it possible to do without an engine completely?

How to make a mini fan?

Let's start with the simplest thing: making blades. If you take a square from an ordinary sheet of paper, cut it diagonally, leaving about a centimeter intact in the center, you will get a blank for a pinwheel. Then 4 sharp corners are bent towards the middle and strung one by one on a nail, having previously stuck it into the center of the workpiece. That's it! It's a pity that this is just a children's fidget spinner.

For functional and useful design take 2 CDs or DVDs. One will make the blades, the second will make a stand for the device.

The used circle is cut into several equal parts (from edge to center). To make the process easier, you can hold the plastic over the fire for a few seconds. Each of the resulting sectors of the softened workpiece is slightly rotated around its axis to form a propeller.

What other components are needed to assemble a convenient mini fan? Here is the list:

• Cork from a wine bottle.
• A cardboard or plastic tube for attaching the engine to the stand.
• Small motor.
• Two wires.
• Cable with USB contact or batteries.
• Good glue, scissors, a strong large nail or awl.

Where to get a micromotor

It happens that household bins contain appliances that no one has used for a long time. These could be hair dryers or mixers, blenders and children's cars. Even a motor from an old tape recorder, player or some other mechanism may come in handy. We disassemble the unnecessary device and remove the engine, having first disconnected all the wires.

Since we are making a mini fan, the motor is from an old one washing machine, refrigerator, vacuum cleaner or other large unit will not be suitable due to its size and noise.

Continued assembly of the device

A hole is made in the plug and placed on the axis of the selected engine. To secure the shaft, it is first coated with glue. Then, a propeller cut from the disk is glued to the part of the axle sticking out of the hole in the plug.

Next, lubricate with glue paper straw in diameter and place it on the plane of the second disk. Then install the motor on top and connect its contacts to the terminals from the USB cable. If, when plugged into the computer port, the propeller spins in reverse side, you need to disconnect the contacts, swap them and solder them again.

By connecting a battery to such a device, you can use it anywhere in the room, in the car, near the pool.

Wind blower without engine

How to make a mini-fan at home without a motor? A very popular option is to create a device using small neodymium magnets.

Take the cooler from the computer and separate 4 transformer coils from its body. Instead of copper windings, you need to install and secure the same number of pieces of magnet. Usually they buy neodyms in the form of half-arcs or extract them from unusable hard drive. The magnets are placed exactly in the places where the transformer windings were removed, that is, along the perimeter of the cooler frame.

As soon as the last piece is secured, the mini fan will begin to rotate. Using permanent magnet technology, it is possible to assemble an almost perpetual motion machine. To stop it, one of the neodymium pieces that replaced the coil is removed from the circuit.

The field of the magnets must be equal in strength to the field of the disconnected coils, otherwise the propeller will not be able to rotate in a constant, stable manner. The poles are placed diagonally, alternating plus and minus.

What to do if none of the above methods are suitable, if there is not enough time or details for homemade fan? In this case, you will have to use a regular factory product.
