How to make a USB fan from improvised means. DIY fan: how to make a homemade powerful fan

The fan is not a complex device. It consists of a motor, blades, various adjustment buttons and a stand-case. There are additional elements, such as backlight, clock, but these are already options that are not so important.

It is not at all necessary to buy a fan, because it is quite possible to make it yourself. Moreover, this does not require special skills of the master.

With due skill, homemade model it will turn out not to be a way to get rid of old things, but an opportunity to show imagination and, possibly, hidden talents. Some craftsmen quite simply get both functional and extremely attractive options. They harmoniously complement the interior and become the center of attention no worse than any art object.

How to make a fan from a conventional electric motor

Probably the easiest and fast way to get a self-assembled home-made fan is to find an ordinary motor, which is most often found in toys.

Standard electric motor from a toy

Ordering such a thing is not difficult. Moreover, today, without stopping for a minute, caravans of various knick-knacks from the Celestial Empire ply. And if not, then just buy an inexpensive one. toy car and remove the motor from it.

But expect the impossible from such a device is definitely not worth it. Rather, it can only slightly drive air. But for desktop model will do quite well. He will be able to blow the face of the person sitting at the computer.

For such a fan, you can use absolutely anything. The main parts will be:

blades;
motor;
on/off button;
stand;
supply system.

Otherwise, the limit of the idea will be only within the boundaries of fantasy.

After the motor is ready for use, it makes sense to take care of the power. These can be batteries, as in the toy for which the motor was intended. But, of course, such energy will not last long. However, there is a plus - the device will remain compact and mobile.

The second option is mains power. But in this case, don't overdo it. Direct connection through the plug is a sure way to burn out the motor. So do not experiment, trying to spin the engine up to high speeds. On toys, electric motors are usually designed for 3-4.5 Volts, and the desire to give more rotation due to powerful energy sources, firstly, will quickly land the source (if it is a battery), and secondly, it will seriously reduce the life of the fan up to breakage. The motor will start to heat up, the brushes may melt.

But modern chargers convert the voltage in the network, reducing it to set parameters. You can find a power supply, including on sale, which is ideal for the motor.

To create the blades, you can already take any material. The main thing is that it should be light. Due to the weakness of the motor, the less the blades weigh, the faster the rotations will be, and, therefore, the efficiency of the work.

The easiest option is to take a cork from a regular plastic bottle, which will serve as a fastener for the blades. Make a hole in the bottle according to the size of the rotating axis of the electric motor.
Blades can be made from a regular CD. A hole is burned in the center according to the size of the cork from the bottle. The circumference of the disk is divided into 8 sectors. They are cut for some distance, but not to the center. After that, the disk must be heated with fire in order to easily bend the blades. For this, a lighter is suitable.

Creating Blades on CD

You can attach the disc to the cork with glue. The second option - when a hole is burned in the middle for the cork - immediately connect the structure. The melted plastic will harden and hold firmly.
After all this, the structure is interconnected. Wire is suitable for the stand. This is perhaps the easiest option. And for such a light device, you can’t imagine better. You can bend the skeleton in such a way as to discreetly hide the batteries there. Or carefully run the power supply wire going to the motor.
The circuit should not always be closed if batteries are used, so a button must be fixed on the case. She is inexpensive. You can use it from the toy from which the motor was removed.

Another version of the propeller device is the use of paper, only thick. The method is even simpler, but less practical.

Advice! When experimenting, remember that the larger the fan blade area, the more noisy it will be. On the other hand, small blades do not move air as efficiently.

How to make a paper fan

Paper is not the best suitable material for a home fan for the simple reason that it is very impractical. Any ingress of water, even banal humidity - and the device will rapidly begin to lose its rigidity.

But despite all the disadvantages, craftsmen even quite nice samples are made from paper. Of course, we are talking about thick paper or cardboard. Strong material from boxes is good. A regular motor or cooler, an on / off button and wires are also useful.

Simplest table fan using cardboard

An approximate design plan is that the device can be simplified as much as possible. The impeller is easy to cut and can have many or few blades. All at the request of the master. The motor can be mounted on a wooden or cardboard bar. The stand will also go from paper or an old computer disk.

It is only important not to forget that such a fan turns out to be very light, which makes it shaky in operation. Therefore, it is necessary to further strengthen the body. Old batteries, bolts or nuts are good.

How to make a plastic bottle fan

favorite raw material crazy hands» - plastic bottles - almost ideal for creating your own fan. For the propeller, the upper part of the standard round bottle. It is necessary to cut off the part with the cork just above the glued label.

The part of the bottle with the cork will be the blades. To do this, the plastic before the cork needs to be cut so that several different petals are obtained. After one, the petals are cut off at the base. The rest are the future propeller blades.

Plastic bottle fan blades

To shape the blades and twist them a little, you can use a candle or a lighter. The main thing is not to overdo it, because the plastic is soft and can catch fire. The task is to warm it up a little, and not set it on fire.
The cork will be the base of the propeller. A hole is made in it according to the dimensions of the axis of the motor. To keep the connection firmly, you can put it on glue.
Now is the time to think about the foundation. The rest of the plastic bottle is also suitable for it. A hole is cut in it to firmly place the cork with the blades at a right angle. It is necessary not to forget to weight the base - with nuts, bolts or any other metal objects.
A hole is made on the base for the button and the chain is assembled. There is also enough space for the power supply.

The field for imagination when working with a plastic bottle is extensive. You can use several bottles at once. One will become a propeller (more precisely, part of it), and the second will become a good base. But then you will need Additional materials. For example, regular drinking straws.

Simple and lightweight bottle fan

How to make a usb fan

But the most convenient and simplest fan is exactly the old cooler, which can also be used. For example, put it on the table, and it will cool, only not the processor or video card, but the person.

The advantages of this design are obvious: the cooler is very reliable, because it is his job to constantly turn the impeller and cool something. Yes, and getting coolers is easy. Enough to either find old computer, or order a new fan or buy it in a store.

The cooler device is simple. This is a ready-made fan in a plastic case. Two wires (usually red and black) depart from it.

Regular computer cooler

Making a USB fan is a matter of minutes:

The wires on the cooler are stripped by 1-2 centimeters.
A regular USB cable is taken, at the end of which you also need to get rid of the insulation. The standard USB cord has four wires inside. Of these, you should choose black and red. Cut off the rest so as not to interfere, and clean up the necessary ones.
Connect the red wire of the cord to the red one on the cooler. Black - with black. Carefully insulate areas without winding. Ready.
It remains only to think about the holding device. Here the already familiar wire, which takes any shape, can come in handy. For a fan case, it will do even cardboard box, and if you spend a little more time and effort, you can even build a real design object.

Design approach to the design of the fan

It is very convenient when the fan turns on when you start the computer. In addition, modern blocks have several USB outputs at once. It turns out that such a device will not interfere.

Another point - sometimes you want to turn on the fan regardless of the computer's operation (especially since a device with a cooler turns out to be quite powerful, good and useful). Then you can use adapters. For example, phones today make chargers that easily turn into a USB cord when the plug is disconnected. Similar equipment can also be used for a fan, making it universal: powered from the network and from the USB port of any computer. Another plus of this design is the simplest electrical circuit. A cooler-based fan can even do without extra buttons: just a wire and a plug.

DIY bladeless fan

But a slightly uncommon use of a free cooler (but you can get by with an electric motor) is a bladeless fan. Modern, interesting, with due skill - no less effective - a solution that definitely attracts the eye. The thing turns out to be completely non-standard, spectacular.

For example, here's the perfect appearance bladeless or duct fan model:

This is how you can make a bladeless fan with your own hands

The most important thing about bladeless models is, of course, their appearance. Therefore, if you make such a device yourself, then you need to try to think through the frame in great detail. Rough edges, roughness - all this will spoil the impression.

The case of a bladeless fan is almost entirely a working area. Do not think that some space technologies are implemented here.

Air circulation is carried out quite prosaically - with the help of rotating blades. They hide in a tuba base. If you take a cooler from a computer, then you can make a stand according to its shape. Here, as they say, at the discretion of the author.

The differences from the classics are in the location of the cooler - it is placed horizontally in a bladeless fan.

Location of the cooler in a bladeless fan

The upper ring is made hollow inside, two-layer. There, the main redirection of air in the right direction is carried out.

A hollow cavity is visible in the upper ring of the fan, from where air blows

You can make the frame of a bladeless fan out of plastic, wood, thick cardboard. It is better to use a flexible material so that it can be easily shaped into a ring. Alternatively, use a combined structure. For example, rings are made of cardboard or plastic, and the frame is rigid - made of wood.

You need to cut out:

four faces for the stand;
Two circles of the same radius;
Twist two rings of different diameters.

Then everything is connected together, if necessary - painted.

Meals can be organized in different ways. A universal option - a combined cable for a USB connector and a plug-in plug for an outlet.

The device can also be slightly complicated. For example, make a light strip along the edge of the rim from diode tape. The backlight consumes little energy, but it will add beauty to the fan. And the power supply and wiring, if necessary, can be easily hidden in the stand.

How to make a powerful fan with your own hands

When it comes to powerful fans, you need to understand that they require completely different motors. Starting from the motors of old fans, ending with others household appliances. Well suited:

unnecessary ceiling chandeliers with fan;
old lawn mowers;
drills;
hoods.

The only thing you need to get into the voltage corridor, which is required to power the motor. For example, drills most often need 18 volts. But for ventilation purposes, it will be sufficient to supply less than half of this voltage. Even at 12 volts, the fans are very loud and extremely unstable due to the strong inertia of the rotating blades.

Power for powerful electric motors must be done from the network. Therefore, you need to think about installing a power supply or connecting a charger. The wiring diagram can be complicated by adding light bulbs lying around, Digital Watch, radio, toggle switch or board for switching operating modes. But it's easier, of course, to limit yourself to only a fan with a button, if that's enough.

In any case, such homemade variations of homemade fans are sometimes much better than even purchased options. With proper skill, a very good thing can turn out, the real pride of the owner.

Working in the summer at the computer, or just on vacation, sometimes you want a slight breeze, a “local” coolness. The airflow of an office air conditioner doesn't provide the sweet comfort of a gentle, directed blow 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 field since ancient times is folding fans. They were made from colored paper and ostrich feathers, from painted silk and carved bamboo sticks. Such a device has only one drawback: to obtain such a desired coolness, you need to hold it in your hand, which is not always convenient. It is ridiculous to imagine a manager or an economist working at a computer and fanning himself with a fan.

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

What will be the rotating propeller, from what material.
Where can I get a motor.
From what power source will the device work.
Is it possible to completely do without an engine.

How to make a mini fan?

Let's start with the simplest: 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 get a blank for a turntable. Then 4 sharp corners they are bent to the middle and alternately strung on a nail, having previously stuck it into the center of the workpiece. That's all! Too bad it's just a baby spinner.

For a functional and useful design, take 2 CDs or DVDs. From one you get the blades, from the second - a stand for the device.

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

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

Cork from a wine bottle.
Cardboard or plastic tube for mounting the engine to the stand.
Small motor.
Two wires.
USB cable or batteries.
Good glue, scissors, a strong large nail or awl.

Where to get a micromotor

It happens that in the home bins are stored appliances that no one has been using for a long time. It can 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, after disconnecting all the wires.

Since we make a mini fan, the motor is from the old washing machine, refrigerator, vacuum cleaner or other large unit will not work due to its size and noise.

Continuation of the assembly of the device

A hole is made in the cork and placed on the axis of the selected engine. To fix the shaft, it is pre-coated with glue. Then, a propeller cut from the disk is fixed with glue on the part of the axis sticking out of the plug hole.

Next, glue the paper tube along the diameter with glue and put it on the plane of the second disk. Then the motor is installed on top and its contacts are connected to the leads 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 turbine without engine

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

They take the cooler from the computer and separate 4 transformer coils from its case. Instead of copper windings, you need to install and fix the same number of pieces of a magnet. Usually they buy neodymium in the form of semi-arcs or remove them from an 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 fixed, the mini-fan will begin its rotation. Using technology with permanent magnets, it is possible to assemble an almost perpetual motion machine. To stop it, one of the pieces of neodymium 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 mode. The poles are arranged diagonally, alternating plus and minus.

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

Consider how to make a fan with your own hands using the example of a bladeless device made of PVC pipes, a plastic container and a fiberglass sheet.

The best part about this bladeless fan is that, unlike most homemade devices, the project does not require the use of 3D printing, and the final cost can be even less than $10.

Tools and materials for the manufacture of a bladeless fan

The tools required for this project are very easy to assemble and are all pictured above. The main thing for this project is a set of PVC pipes with a diameter of 6.5 and 3.5 inches, Plastic container or bowl and 3mm fiberglass sheet.

There is no need for a 3D printer as is used in most DIY fan projects. What's more, we used a miter saw to make most of the cuts as it made the job more precise and easier than a hand saw.

Despite the name of the device, which indicates that the design will be without blades, the fan actually has a fairly high-speed blade inside the main body. You can see the principle of operation of the device in the figure above.

In addition, the bladeless fan provides closed blade control, and then the air flow is directed through the closed channel body, following the structure of a conventional bladeless fan housing. This design offers an excellent level of protection for children.

How to make a fan with your own hands - the main body

First you need to make the main body and for this you can use a PVC pipe. The main outlet is made of 6" diameter PVC pipe that is 4" wide to form the outer casing of the air outlet.

To form an air pocket inside the main air outlet, we use a conical shaped bowl that fits perfectly on a 6" PVC pipe and its collar sits on the edges of the pipe (see photo above). Cut off the bowl 1 inch above its bottom so that it forms a nice tapered collar inside the main exhaust casing which allows the air to rotate evenly inside the exit cavity before leaving it.

Inner casing and base

The inner clamp for air outlet is made of PVC pipes 5 inches in diameter. This tube forms a narrow opening nearly 0.5" wide for uniform distribution air from the cavity/air outlet. Three parts, namely the outer 6" PVC pipe, the conical inner case made of plastic bowl, and the inner collar made of 5" PVC pipe, together form the air outlet case.

To form the base, use 3.5" PVC pipe cut to a height of 5". To make the base fit perfectly with the air outlet body, cut one end of the base pipe in curved shape(we cut the bend along the pre-glued electrical tape), and designate the contour with a 6-inch PVC pipe. The pipe is then cut with a jigsaw and then sanded sandpaper to perfectly fit the outer 6" pipe without any gaps between them.

Scheme

Air intake hole

Before gluing the base to the main body, drill a 3″ hole in the 6″ PVC pipe, which will be the passage for air to enter the main body and then to the outlet. The hole is made with a hole saw.

The base is then glued to the outside of the air outlet with superglue. Since the base pipe is perfectly shaped to sit on a 6" PVC pipe, superglue makes a very strong bond between the two pieces.

Air outlet ring

The air outlet ring is made of 3 mm thick glass fiber sheet, which serves as a connection between the inner half and outer half main air outlet. The ring is made using a jigsaw.

Painting

Since most of the parts of the bladeless fan case are ready, we need to paint them so that they look neat and flawless. Paint everything white using spray paint, except for the fiberglass ring, which is protected from paint with duct tape.

The end result is very good, and the blue fiberglass sheet looks fantastic against a flawless white background.

LED Strip Light

To make the design more attractive and elegant, add 12V LED strip on inside air outlet at the end where the fiberglass sheet will be glued to the inner air outlet sleeve. The light strip is cut to the required length. Tape has a sticky side and sticks when removed protective coating from the back side of the tape, and then stick to the PVC body.

Instructions for creating from a webcam

When the fan turns on, LED Strip Light illuminates the back of the air outlet and thus produces a very cool visual effect by spreading blue light.

Bonding of all parts

Once the paint is dry, glue all the pieces together to form the main body of our bladeless fan, using superglue to hold it all together.

Mounting the fan in the case with your own hands

Behind every bladeless fan there is a fan with blades. So to drive our fan, we need to use a 12V high speed fan direct current, which can be taken from an old computer. More specifically, in the lesson, a server fan, which is much more powerful than a regular PC fan. Therefore, we strongly recommend using this type of fan.

The fan is mounted inside the base directly below the air outlet housing with four wood screws to hold the fan securely in place. The fan is mounted in such a way that it blows air upwards, so we need the fan to be stable enough.

How to make an air intake in a fan with your own hands?

A pair of air intakes is made just below the server fan on both sides of the base pipe, that is, the base pipe. These inlets allow air to be sucked into the base.

To prevent someone from accidentally injuring their fingers by inserting them into the base of the fan, we glue a metal mesh on both holes. The mesh is first painted matte black and then glued inside the base with hot glue.

Speed control unit - fan speed controller

We decided to use the idea of a PWM speed controller for this fan in order to regulate the amount of air coming out of the fan and thus the noise level. For this, it was developed simple circuit PWM speed controller, as well as a dedicated printed circuit board using AutoCAD Eagle.

The scheme works on the basic principle. It uses a 555 timer IC that switches the transistor several times in every second, and the switching speed depends on the resistance provided by the potentiometer. So by turning the knob, we can adjust the output pulse and thus control the fan speed from the server.

The archive below includes all files, including schematics, material sheet and Gerber files for the PWM circuit, that you may need.

You are sitting at the computer, summer is outside, there is no air conditioning. The hand is already tired of endlessly fanning itself with a newspaper, and sweat drips from the forehead onto the keyboard. Familiar situation? If there is no extra money, a homemade fan will help. To make it, you do not need to run to the store for details. Everything you need for a blower is in the house. Don't know how to make a free fan at home? Follow the text!

What is an air cooler made of?

engine
fan blades
stand
power supply

The last point can be omitted if you do USB fan with your own hands. The computer has a voltage of 5 volts. You will need a printer cable, an old "mouse", or any unnecessary device with a USB cable.

If you are a fan of homemade products, there is probably useful trash in the house. Otherwise, you do not need to know how to make a fan with your own hands.

Did you find an electric motor in the box with unnecessary parts? You can make a fan out of a motor from an old drive or a broken toy. Consider a few examples of how to make a mini fan from improvised materials.

Glue, cardboard, toy motor

To make a small propeller, you will need a piece of corrugated cardboard 30 × 30 cm.

We glue the support in 2-3 layers, the area is not less than two palms. We make a rack for the engine in the form of a prism 10–15 cm high. For cutting, we will use a clerical knife. We bend the design along the line.

How to make a mini fan durable and stable? Let's use glue gun. No other adhesive will make the connection as secure.

We connect with hot glue, and as thick as possible: the design should turn out to be monolithic. The blades can be made from thinner cardboard. suitable packaging from a mobile phone accessory.

This is the most critical element: the blades must be exactly the same in shape and weight. Otherwise, your propeller will vibrate during operation, and quickly fall apart.

We glue the blades (carefully) on a cardboard sleeve, observing aerodynamics. The planes should be turned 30–45 degrees in opposite directions. For simplicity of design, we assemble a USB fan with two blades. They are easier to balance, and such a propeller will cope with cooling no worse than a three-blade one.

Trial run and balancing

We make a hole in the very center of the bushing (using an awl), put it on the motor axis, and carry out a test run. Of course, before assembly, it is necessary to coordinate the angle of attack of the blades with the direction of rotation of the motor. Otherwise, the fan will blow in the opposite direction. If vibration is present, the propeller can be easily balanced by simply crawling the blades. After making sure that the propeller spins smoothly and blows where it is required, we glue the motor onto the stand. Clay do not feel sorry!

We connect the USB cable to the power wires of the engine. Of course, it is better to do this with a soldering iron, but given the meager power, you can get by with a simple twist. The main thing is not to forget to insulate the connection with electrical tape or tape.

How to determine the power contacts of a USB wire

Any USB connector consists of 4 pins. We are not interested in the middle ones, these are information wires. The 5 volt supply is at the extreme contacts. Desoldering in the illustration:

If you reverse the polarity, nothing bad will happen. The motor will just spin in the wrong direction. How to determine the motor supply voltage? There is no need to look for markings. If the toy (where it was installed) is powered by three batteries (1.5 volts each), then the motor is 5 volts. If it is powered by two batteries, it will not work for USB power.

CD

You don't know how to make an efficient CD fan? It's easier than it looks. We mark the disk into 8 sectors. Even number blades are easier to balance if axial runout occurs.

Cut out the blades with regular scissors. You can do this work with a construction knife, or melt the sectors with a soldering iron - there is not much difference. If you inadvertently break a CD, get a new one.

The extra segments are broken out, the rest are given the aerodynamic shape of the propeller. To do this, it is enough to heat the workpiece over a candle or with the help of building hair dryer. If you make a mistake with the geometry, you can always correct the situation by reheating. This is the advantage of crafts made from a CD.

Glue a thickening in the center of the structure: any piece of plastic 5-10 mm. We drill a hole in it for landing on the motor shaft.

Where to get an electric motor

In this design, a drive from a disk drive is used. Power supply 5 volts, moderate speed. Most likely, you do not have a separate disk drive gathering dust on the shelf, it can be found in system block. No one uses floppy disks anyway, you can safely disassemble it for spare parts.

Convenient flat motor housing allows you to assemble the fan on a flexible leg. To do this, we twist a piece of single-core copper wire into a pigtail, and wind it to the power cable with electrical tape.

A motor with a propeller is glued to a flexible stand either with hot glue or wrapped with the same electrical tape. Unless you're going to enter a fan design contest, you don't have to worry about aesthetics.

After spending 2-3 hours, you get a convenient portable "device" that can be installed anywhere without leaving your computer.

Aesthetics from a plastic bottle

If you want not only fresh air, and to make the product pleasing to the eye - we use other materials. The basic components remain the same: a motor from a child's toy and an old USB cable. By the way, you can connect such a fan to a 220 volt outlet using a smartphone charger (with that de USB port).

The highlight of the design is the body. The propeller is made from a plastic bottle. The twisted plug will serve as an axial sleeve. The rack can be made from a bunch of straws for a cocktail.

We assemble an elegant base from the second PET bottle and a CD glued from below. With free accessories, you can install a connector and a switch.

Despite the “lightness” of the design, the fan turned out to be quite stable. If necessary, you can put some weight in the case.

Using Factory Parts

We return to the presence in the home workshop of conditionally unnecessary components for the computer. For example, a cooler from a power supply or a system unit.

The electrical part of the work is reduced to a minimum. If the power supply is 5 volts, we work according to the scheme: USB cable. To supply 12 volts, you will have to look for a power supply, or a phone charger. In addition, there are "turbines" that are connected to a 220 volt network.

Actually, to make a fan out of a cooler from a computer, it is enough to fix it on some kind of stand. And if you use batteries instead of a USB cable, you can organize a flow of fresh air anywhere.

Making a fan with a computer cooler

To make a fan at home and not strain at all, we found this method on the open spaces of the network. The entire manufacturing process will take no more than 20 minutes, you can use old coolers or just buy a new one in the store, the price for them is now a penny.

First, we begin to prepare the cooler, it has two wires: red and black. We remove the insulation by 10 mm from each wire, there is even a device for stripping the insulation. The size of the cooler does not play a special role, of course, it is better if it is big size, the wind flow will eventually be stronger.

We begin the preparation of the USB wire, for this we cut off one half at the place of the main cut and remove all the insulation. We will get four wires: two black and two red, we also clean them. If the cooler has other green or white color cut them off, they just get in the way. Learn how to make your own thermoelectric generator.

In the end result, you need to connect the wires to each other, there can be several ways, the main thing to remember is the color coding. Do not forget to isolate everything among themselves, the more isolation, the better. For convenience, the finished cooler can be installed in a regular shoe box, so it will be more stable.

This is how the guys in the video suggest us to make a fan out of a cooler. The method is actually simple, we do not promise strong airflow, but working at a computer will become much more pleasant.

How to make a USB fan with your own hands using a motor

So, to make a fan from a disk motor and usb, we need more time, but this type of fan will look better. Everyone can make such a device, the main thing is to show a little desire and patience.

First of all we have to make the blades for our fan, we recommend using a regular CD, it looks great and is quite easy to make. Also read an interesting article where we make a laser level.

Here the guys from the video show a really cool way. In a similar way, you can make a fan out of paper, but remember, the paper must be thick, it is optimal to use cardboard in general.
