Hot. If I may say so, even too much. That is why you can think about how to make a fan. You will say that it can be purchased at the store. But, firstly, their cost increases significantly. Secondly, they are quickly sold out and it is not always possible to find what you need on store shelves. Therefore, several practical advice about how to assemble a fan. After all, it is quite possible to arrange it even at home from available materials. Here are a couple of options.

How to make a fan based on an old cooler. If you have an old one, you can take it from there. You can also borrow a switch there. In order to make a homemade fan, you will also need some kind of battery holder. There are many of these, you can take it from some broken toy or something else in the same spirit. Of course, you will also need several batteries themselves. All that remains is to connect all these components together, and a simple fan will be ready. If you don’t want to bother with the holder, you can use a regular USB port to supply power. The stand can be made from anything. It all depends specifically on your own imagination and what you have at hand.

You can, for example, make a stand from ordinary rigid wire attached to something. It is not so important what materials will be used, but how stable the entire structure will be.

Another option on how to make a fan may be useful for enthusiasts. Computer disks are an excellent tool for making. What else is needed? A motor from a simple toy, a cork left over from champagne, some kind of handy switch and several batteries. We take the disk, and then make as many cuts as we need for the blades. It is necessary to leave about a centimeter to the inner edge. Then turn each blade slightly at an angle. It bends much better if the disk is heated, for example, over gas. Then you will need to insert a champagne cork into its center. If you make a small puncture in its center, for example, with an awl, you can easily attach the entire structure to some kind of pin. You will need to make a leg - absolutely any cylinder-shaped object that can accommodate batteries and wires can play its role.

You will also need to design a base for the entire unit - it can also be anything, the main thing is that it is stable and can support the structure. All that remains is to add a few additional tips - when cutting out the blades you need to make sure that each of them is approximately 45 degrees - you will end up with about 8 pieces. The plug inserted into the center of the disk will need to be secured with glue. In any case, the process should not cause you any difficulties.

If you've been thinking about how to make a fan, you now probably understand that it's very simple. Each of the proposed models is extremely easy to manufacture, and you will not need much time to create it. You don’t need any special things, the above is quite enough. These fans are very convenient and compact. You can put it on your desktop. Or, if there is such a desire, take it with you to the garage or country house, where these devices will serve as cooling means. It is difficult to argue with the fact that they have tangible dignity - after all, these are collected, according to by and large, very useful things from various trash.

As you can see, it is quite possible to make a fan yourself, from scrap materials, without bothering with going to the store and looking for a unit that suits you at an affordable price. Everything is much simpler.

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 its production is incredible. interesting activity, 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 is a detailed description of the manufacture of options, the effects of which 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, for local impact on a user who spends a long time at the computer.

Let's prepare starting materials to do the job:

• 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 old toy, for example, from a typewriter. A roll sleeve slightly ennobled with decorative finishing paper is suitable as a cardboard tube. toilet paper.

The main advantage of this model is that almost any do-it-yourselfer will have all the materials needed 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 equal 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 ideal 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 expanded. If you don't have a candle, a lighter or a soldering iron will do.

Should be heated central part disk, and turn all the blades in the same direction. Place in the disc hole wine cork. 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.

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;
• Styrofoam;
• hot glue gun.

So, we take an ordinary 1.5 liter plastic bottle with a stopper. At the level of the label line, cut it off top part. This is exactly what we need to make the propeller. We divide the surface of the 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.

From time to time the need for a kind of fan arises, but small models are relatively expensive. There is no need to rush to shell out money, because a small fan can be easily made with my own hands. In terms of efficiency, it is not inferior to purchased analogues, and its creation will require a minimum amount of materials.

Making a fan from a cooler

The simplest way to make a fan yourself is to use an unnecessary cooler (these are used in computers as a cooling system for components).

It is not surprising that this method is the simplest, because a cooler is a small fan. There are only a few things left to do simple steps to give it its final shape and performance.

The cooler itself is quite functional, but you need to prepare it for non-standard way uses:

1. Wires.

If the fan is located next to the computer, a regular unnecessary USB cable will do. It needs to be cut and the insulation removed (the same with the cooler wires):

We are only interested in two wires: red (plus) and black (minus). If there are other colors in the cooler or USB cable, feel free to cut them off and isolate them, since they are absolutely unnecessary and will only get in the way.

1. Compound.

After cleaning, the wires need to be connected to each other (it is enough to twist them tightly together). Don't mix up the colors. This threatens serious complications in the process of creating a ventilator.

A length of 10 mm is sufficient for twisting. If necessary, you can clean most of the wire, this is not scary, but you will have to insulate much more.

1. Safety.

Remember that proper insulation is the key to success and a guarantee that the computer or outlet will not short out. Bare wires should be covered with electrical tape (exclusively in the absence of power), and the thicker it is, the better.

There is no particular point in explaining what threatens the fall of “minus” to “plus”. If the red and black wires come into contact while transmitting electricity, not only the USB cable/port, but also the computer components may burn out.

In principle, computers are not afraid of such moments if they are equipped with protection against voltage surges. But when a wall outlet is used, repairing the wiring in the apartment will be much more difficult than creating a small fan.

Therefore, take serious care to insulate the exposed parts of the wires. Rarely does anyone need unnecessary complications.

1. The finishing touches.

Don't forget that a computer cooler is very light, but at the same time very fast. Even with a voltage of 5 volts, its speed will be quite high. We consider this voltage for a reason: the cooler will do its job perfectly, and the operation will be as silent as possible.

Due to the small size of the device, it may fall due to vibrations. This should not be allowed for the following reasons:

• Such a cooler cannot cause lethal cuts even during operation, but there is no guarantee that the device will not jump up and fly off, for example, into the face;
• if it falls on a non-flat surface (on a pencil, pen, lighter), its blades can be damaged: fragments breaking off at such a rotation speed can cause irreparable damage;
• other unforeseen circumstances.

Therefore, it is important to secure the cooler (with tape, glue) to some more stable surface: a box, a wooden block, a table.

1. Additional functions.

If desired, the finished fan can be updated externally, a switch can be added (so as not to pull out the cord every time), etc. But attention is also paid to a method that increases the efficiency of the device relatively well.

Simply cut off the top plastic bottle and glue it (with a wide hole) to the cooler frame. Thus, the air flow will be more accurate and directed: the force of air movement will become approximately 20% stronger, which is a pretty good indicator.

At this point, the creation of the fan is completed, and it is ready for full operation.

Disc fan

If the previous option does not suit you, and you want something more complex, then consider self-creation fans from computer disks:

1. Engine.

Since we don’t use a cooler, we need to get some kind of motor that drives the blades of our future device. In fact, you can also use the motor of the already mentioned cooler of the cooling system, but this is too simple.

You should find or buy a motor with a specific part that moves (for example, a protruding iron rod). Since we are making a fan from disks, then the presence of such a rod will the best option. Motors from an old VCR or player are also perfect, because they spin discs and cassettes - just what we need for the spinning propeller in our fan.

You should not use an engine made from washing machine or even a past fan - they are extremely powerful. Due to the self-assembly of the structure, it will be very flimsy. In the very first seconds, a strong motor will scatter fragments of blades throughout the room and fly off the base.

If there is a running motor, it must be secured with wires in the previously mentioned form.

Having a running engine in hand, you need to concentrate on the disks, which are the main components of our fan. First of all, cut one into 8 equal parts:

To avoid mistakes during the procedure, you can first mark the disc with a pencil. It is best to use a soldering iron (there will be no sharp edges, it is safer), but regular scissors will also work.

Afterwards, the disk should be slightly heated with a lighter so that the material becomes more pliable, and the wings should be bent in the manner of blades, like conventional fans:

You can do the same with regular plastic bottle:

We need to put it in the center of our propeller wooden cork from the bottle. If the size is too big, it can be planed.

1. The remaining parts.

You can use a regular toilet paper roll as a center holding the entire structure:

It should be secured in the center of the second disk, which will act as a foundation for the fan. You can place half of the second bushing on top, as seen in the photo, so that the motor is inside it. You need to hang the blades from the disk/bottle on it.

The fan is ready for operation. If desired, you can add decorative elements to make the device look more presentable.

You can see clearly how such a fan is made from a bottle in this video.

Additionally, it should be recalled that important points when creating a homemade fan:

1. To fasten the parts together, you need to use high-quality “superglue”.

Exactly the one that you can’t peel off even if you want to. The entire structure must be as stable as possible and not succumb to vibrations and fluctuations. Be responsible and fill everything you see with glue except the blades and internal parts of the engine.

1. Take your time.

You risk missing out important detail, and this significantly increases the chances that something will go wrong during the operation of the finished fan. The consequences can be quite serious.

1. Do not use inferior components.

If you don’t need the motor that is used to create the engine, its performance may be in doubt. Make sure it will last for some time and be effective.

Building an engine from scratch is a highly specialized process and requires a lot of knowledge. Make sure that the motherboards are in order, that all necessary connections are sealed well, etc. It is better to check again than to make another fan later.

1. Insulation.

We remind you once again: do not forget about high-quality winding of wires with electrical tape. You should not save it, because short circuits and their repair will force you to sacrifice big expenses. Perhaps even in a monetary sense.

The hand-held fan is quite compact, efficient and does its job well. It is not difficult to do if you take the procedure responsibly and follow the instructions. There are no restrictions on dimensions: if you feel strong, feel free to start assembling the fan bigger size.

In contact with

When hot summer days arrive, home cooling can become a problem. Not everyone has their own fan in their room. This is a fairly serious problem, especially since last years Summer is getting hotter. Today we will tell you how to make a fan from a cooler. In fact, there is one interesting method for getting out of a difficult situation. Almost every person in the house has a lot of spare computer parts that can be used for their intended purpose, or you can simply build something useful out of them.

The fan from the cooler is optimal solution room airflow problems.

A fan from a home PC cooler is the optimal solution to the problem of room airflow. Yes, its power is not so great, but for small room it will be quite enough. Making a cooling fan, by the way, is extremely simple. To do this you will need some tools and materials.

Tools and materials

To work, you must have the following:

• a piece of cable with a USB connector;
• soldering iron;
• solder;
• flux;
• wire cutters;
• with a knife;
• cooler

That's basically all you might need. These tools and materials can be replaced with others if a different type of wire connection technology is used.

Return to contents

The cooler will create a flow of cold air that will bring coolness into the room.

So, now we have everything we need to carry out the work. A cooler can have many different wires, because today computer elements are made that have their own brain. There are wires here that serve to transmit information to the device, which allows, if necessary, to increase or decrease the speed of its rotation. These elements are not needed for operation. Only the red and black conductors should be left. They are the ones who supply power to the device. All other wires should be cut off using wire cutters. This must be done extremely carefully so as not to damage those that will be used in further work.

Next, take the USB cable. It doesn’t matter whether it will be working or if it will be missing some of the wires, the most important thing is that the red and black wires are also present here. The rest should be cut off, although they may simply not be used, but for easier subsequent connection to the cooler, it is still better to remove them. This is also done using the most ordinary wire cutters. So, two cables are prepared, which means that you can safely move on to the next stage of work. It is worth remembering that the USB connector is used for power. A standard 220 Volt outlet is inappropriate here, since operating voltage The cooler's power supply is standard for personal computer and completely coincides with the one issued by USB.

The most important thing in a USB cable is that there are red and black wires needed to make the fan.

The next step is to strip the red and black wires. You can do this using the same wire cutters, or you can use ordinary knife. Here everyone does the work in the way that seems most convenient to them. The stripped wires must be twisted to form a single wire. Next, each end should be tinned. To do this you will have to use a soldering iron, solder and flux. The device must be preheated. To do this, the soldering iron is turned on standard socket 220 volt. To fully heat it up, you should wait about 10 minutes, although in this situation everything directly depends on its power. The higher it is, the less time you will have to wait. When the soldering iron has warmed up, it should first be dipped into flux, which will create the necessary atmosphere for melting the solder. You can use the standard tin-lead version for such work, since you will have to solder ordinary copper. Rosin can be used as a flux, or acid can also be used. It all depends on what a person has in his home.

Continue the workflow

Next comes the actual tinning; everything needs to be done extremely carefully. Molten metal thin layer applied to conductors. Moreover, all four wires that are to be connected are subjected to this procedure. Now you can safely connect all the conductors to each other. To do this, they are pressed against each other, and then warmed up using the same soldering iron.

To make a connection, sometimes it is enough to hold the heated device on the wires for a few seconds. Now you need to check the strength of the connection. To do this, pull the soldered wires. If the soldering is good, then they will be tightly connected to each other. At this point the process can be considered complete.

Of course, you shouldn’t immediately insert the connector into the USB, because there is a high probability that something will happen short circuit. The conductors must be insulated. For these purposes, in most cases, ordinary electrical tape is suitable. It is best to wind it not in one, but in several layers at once. This will increase the protection level of the device.

Now all that remains is to place the finished fan on the table, then insert the cord into the corresponding connector on the system unit. Surely he will start blowing. In this case, of course, it will not have any adjustment of the rotation speed. For this purpose, additional devices must be included in the chain. For example, you can install a voltage regulator. This device will allow you to reduce the rotation speed of the cooler by changing the resistance.

The regulator is installed in the circuit.

He often looks normal mechanical regulator. Of course, you can do without this option.

Summer has arrived, which means heat, heat and an eternal lack of coolness. But this problem can be fixed, and quite easily. You only need a few details and a little free time to make your life easier with your own hands, to fill it with the slight coolness that you will certainly get by making a USB fan at home. Of course, you can go and buy a fan in a store, but how nice it will be to sit next to the same computer, and a light breeze from the USB fan you created will blow on you. And a thing created with your own hands always pleases not only the eye, but also develops self-love.

We invite you to watch a video of a homemade USB fan:

Tools for usb fan:
- A regular CD (not necessarily new);
- The tube of silicone glue is empty;
- Wooden block;
- Mini disk;
- USB cord;
- Motor;
- Holder;
- Adapter;
- Silicone glue gun.

You need to make three holes in the tube, one in the lid and two on the sides. Holes can be easily made using a regular nail, which must first be heated.

IN wooden block it is also necessary to make a slot or recess. This can be easily done using sandpaper.

The mini disk easily turns into a propeller. To do this, you need to draw it into uniform blades, then heat a stationery knife and cut along pre-drawn lines. And after that, we heat the base of each blade with a lighter and, using our hands, bend each blade a little to make a propeller.

We take the motor, holder and adapter from a non-working CD drive.

Now let's start assembling the USB fan.

Heat up the glue gun. Lubricate the holder along the axis with silicone glue from a glue gun. The propeller must be firmly seated on this glue. Press on all sides. Then, on the other side of the holder, add a drop of glue and glue the adapter. We wait until the glue dries well. This usually only takes a couple of minutes.

Now take a tube of silicone glue, remove the lid and coat the inside with silicone glue. And we insert the motor inside so that the part that we will connect sticks out of the hole that we originally made.

Then we insert the USB cord into the side hole of the glue tube and connect the ends of the wires to the motor.

You need to pour silicone glue into the recess in the wooden block, and place the wire from the USB cord tightly there, and glue the tube itself with the motor inside to the base of the block. And on the other side of the block we glue the CD with silicone glue.

Now the propeller needs to be placed on the side of the adapter glued to it onto the sharp edge of the motor, which sticks out of the hole in the tube from under the glue.

And finally, our USB fan can be plugged into the network and get that long-awaited coolness.
