How to make a fan with his hands: the best homemade model

The cold winter and hot summer - the weather is not uncommon in our country. If you can escape from the cold warm clothing, the heat will drive only a light breeze. It is this flow of air, we should be getting on the quality of the fan, so as not to catch cold under the air conditioner.

Consider the examples of low-cost but effective and attorneys models of how to make a fan with his hands.

Simple home-made from CD's

The most simple fan can be made from the CD drive. It can be used, for example, for local effects on the user, which is a long time at the computer.

Prepare starting materials for performance:

• CD - 2 pcs .;
• a low-power motor;
• cork from a bottle of wine;
• wire with a USB-plug;
• tube or box of cardboard;
• soldering;
• Candle or lighter, a hot melt adhesive;
• pencils, rulers, paper in the box.

For our purposes, you can use a motor from an old toy, for example, from the machine. As the paperboard tube suitable bit sanitized decorative finishing paper sleeve from the roll of toilet paper.

The main advantage of this model is that all the materials needed for its manufacture, there are almost any amateur to do everything with their own hands

The process of assembling the mini-fan is quite simple.

Take one of the CD's and with a marker divide its surface into eight identical sections. Make it easier just using a piece of paper in the box. Draw a cross thereon of horizontal and vertical lines. Each of the four give the right angles divide in half. Using a cell, make it a snap.

Using a very simple method using a leaf in the box, we can achieve the ideal disk partitioning into eight equal sectors

We impose on our drawing disk so that intersecting line appeared in the center of its hole. Alternately applying to the line diverging from the center of the lines, making marks on the disc. Since identical sections are obtained. To partition a disk on the blade should be along the lines of markup to hold the soldering iron from the transparent part of the edge.

To cut you can use scissors, but there is a danger that in the process of harvesting crack. If soldering is no need to use a knife, pre-heated on the stove. When working with a soldering iron along the cutting edges formed plastic weld, which is easily removed with a knife.

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

Over the flame of a burning candle heats the surface of the disc, so you can deploy the blade lightly. If there is no candle, lighter fit or soldering hairdryer. Heat to be a central part of the disk, and all the blades rotate in the same direction. The orifice disc is placed wine cork. To better fix it, you need to pre-treat the edge of the hole melting.

USB wire should be connected to the motor. If we do not guess with the propeller's rotation direction can be changed about the place, that is to change the polarity. Motor need to be glued to a cardboard tube, and the tube itself - for the second CD, which will play the role of the stand base.

When the plug is installed in the hole of the second support disc CD and cardboard tubes, as well as connecting device have been collected, it is important to impose the propeller onto the motor shaft

Now, the propeller must be "planted" on the future of the fan shaft. We will try to make sure that it is installed exactly in the center. Fasten it in this position is possible by means of hot melt adhesive. After completion of all work, the fan is ready for use.

Although the construction of this device will not take you much time, but the result of work done, no doubt, will make you happy

How to make a similar, but slightly more complicated structure, including the scheme of control, look at the video posted at the end of this article.

Fan-based plastic bottle

What did not make our craftsmen from plastic bottles! It is time to say that the fans have also obtained very good. Perhaps he did not will air the rest of your room, but the one who is forced to work at a computer, will help for sure. We offer two options for creating a fan model.

Option # 1: Model of hard plastic

To do the work, we need:

• capacity plastic bottle of 1.5 liters;
• motor from old toys;
• small circuit breaker;
• Battery «Duracell»;
• marker;
• scissors;
• candle;
• hammer and nail;
• Styrofoam;
• thermobonding gun.

So, take an ordinary plastic bottle of 1.5 liters with a stopper. At the level of the line labels cut off her top. That is exactly what we need for the production of propeller. Divide the surface of the plastic preform into six parts.

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

Cut the workpiece along a line almost to the neck. Turn down the blades of the propeller of the future and cut every second of them. We left blank with three equally spaced blades. The edges of each of the blades should be rounded. We do it gently.

To remove those parts of the blades which are closer to the neck of the preform is better to use hardware knife; do not forget to round off the edges of the blades

Now we will have a small candle. Kindle it. Heat up on it at the bottom of each blade to rotate it in the right direction for us. All blades must be rotated in one direction. Remove the lid from the workpiece and center it in the punch holes with a nail and hammer.

Push-fit plug to the stem of a small motor of. Such motors may be from old toys. Typically, to get them is not difficult. Anchoring tube with an adhesive.

Now you need to make the foundation on which will hold the motor. For this purpose we take, for example, a piece of foam. Fasten on it a rectangle, which can also be cut out of foam packaging. On the upper surface of the rectangle and our engine to which is attached a propeller is fixed. To this end, the foam need to make a hole corresponding to the motor parameters.

To fix the elements of a product using a hot melt adhesive. In his absence you can use other adhesives. It is important to mount itself was the most reliable.

Foam - comfortable material for the construction of stands for the fan because it is easy to shape, but the stand base it is better to weight

On the foam stand is attached a small switch and the power supply, the role played by the rectangular battery «Duracell». Putting a simple circuit, trying to do everything as carefully as possible.

We just have to screw propeller on a plug fixed on the little engine. Our fan is ready for operation.

Stand from foam, perhaps too little weight to give the device the necessary stability. After a sufficient span of the blades it can get quite powerful. Therefore, it is desirable to weight the base model.

Option # 2: The product from a softer polymer

Prepare in advance everything that we need in the course of the work:

• two bottles of lemonade «SevenUp»;
• motor 12 V DC;
• seven thick tubes for beverages;
• a connector for the power supply;
• The power supply unit;
• switch;
• scissors and household knife;
• marker;
• thermobonding gun;
• Super glue;
• plastic ties;
• wire cutters;
• soldering;
• insulating tape;
• CD.

So, there is another alternative construction of homemade fan from a plastic bottle. Take the smaller capacity bottle, for example, from under lemonade «SevenUp». Algorithm future cutting propeller blades is the same as in the previous embodiment. Plastic bottles have this much softer, so give the desired slope of the future of the blades is possible, without resorting to their heat.

The hole in the center of the cork should be done by using for this purpose heated at awl or nail fire. The electric motor 12 V DC, the shaft of which is fixed to the propeller, can be taken from old toys and unnecessary in the dryer economy. Fixing the cap on the shaft is carried out by means of hot melt adhesive. Light propeller fasten the lid immediately.

Talking about this version of the fan construction, we mentioned seven tubes, but if those ducts that there you have a smaller diameter, they will need more: it is necessary that they are plugged into the bottom of the neck blank

The most interesting thing - the construction of the stand. It turns out not only stable, but also attractive. To create it will need seven thick tubes for drinks. It is necessary to glue them together with superglue. A rather strong and nice rack.

To take the upper part of the base of a plastic bottle larger than the one from which we have been doing the propeller. The rack of tubes is pushed into the neck of the preform to about the middle of its length. Fix the rack in this position by a superglue applied onto the neck of the preform.

You can now install the engine on the stand firmly against the hot melt. The fact that the rack itself is hollow tubules helps nicely to hide the wires. We just passed through a central tube. Since the wires are inside the unit base.

In order to further strengthen the construction, use plastic ties that stick hot-melt adhesive to the bar on each side of the motor of so screed lock was covered over by a motor, providing it immobility. Excess tip mounting pliers is removed.

In the plastic surface of the bottle which serves as a base structure, slotted holes for power supply and the switch block connector. Do it better utility knife. Connect the connector for the power supply and switch. The wires should be soldered and insulated. Switch and connector is fixed to the plastic melting.

CD drive, which is becoming bottomed for the future of the fan base, not only is the finishing touch to the work, but also makes the product more stable

To weight the base and make it more stable, erecting to him from the bottom of a CD. To this end, the edge of the plastic blank grease melting and pressed against the disc.

Motor connection to the power supply via the connector, and that the apparatus is activated by pressing the red button, the left

Now, through the connector to connect the power. This can be used as a power supply for LED strip, which is sold in appliance stores. Well, and this home-made ready for use.

To make sure that you have correctly understood the sequence of works, watch the video at the end of this article.

Stylish product without blades

We are accustomed to the fact that the main part of the fan is a propeller. This design feature rotates, creating the necessary air flow. But there are models without paddles. They have become part of fashion, primarily because of its safety for the younger members of the family and for pets. In addition, these products look stylish: they are able to fit into any decor and decorate it.

Ready bladeless fan is not similar to the one device that we used to see, however, it works fine

Like most other things in the service of the person, bladeless fan, too, can make their own hands. Its operation is simple: the base unit is a small turbine, which allows an air flow passing through the side holes.

For work, we need:

• cooler from the computer;
• unit and power connector;
• small circuit breaker;
• thermobonding gun;
• Cardboard or heavy paper;
• scissors, pencil, ruler, compasses and calipers.

In principle, the caliper we need only to avoid mistakes in the size of the product. If it is not available, it is possible to do an ordinary ruler, tape measure or measuring tape.

Getting Started.

To start making body - the base product. To do this, cut out four rectangular pieces of cardboard. To determine the parameters to measure the width of the cooler base. The resulting size will coincide with the width of the rectangles. For convenience, we will operate with specific dimensions. The width of our cooler - 120 mm. This means that the width of the rectangle is also 120 mm.

The body of our products will be built in a small switch and power connector. That they later kept tight enough to shoot with their size. Openings in the cabinet must comply with the obtained values. Make the holes need to the moment when the rectangles become part of the body: cut them in flat objects is always easier.

We need dvenadtsativoltovy power supply and a corresponding cooler, consumes only 0,25A. Given the fact that we have a unit 2A, we can assume that we are very well prepared for the further exploitation of the future instrument.

Now, take the cardboard sheets from which we have to cut out the main elements of the fan. First draw the two circles. The radius of each of them is 15 cm. Cut both circles. In one of them, let's call it A, we draw the inner circle of radius 11 cm. In the second, which we call B, the radius of the inner circle is 12 cm. Carefully cut out the inner circle. Received rings A and B.

The resulting ring will be attached to the body of the product. In order to better adhered to the body surface will do one of the rectangular blanks to each of the rings and srezh segment, which corresponds to the flat side of the rectangle width.

Can be securely glued to the base of the ring on which they are installed, you need to maximize the area of ​​contact: for this sector, and cut off the bottom of the product

The main part bladeless fan has a cylindrical shape. We need a strip of cardboard with the following parameters to make it: the first - 12h74sm second - 12h82sm third -15h86sm. During assembly, it will be clear what to do with each of the three bands.

Before assemble a housing in the bottom of each of the rectangles cut out recess. So not only do we do the legs for the future of the fan, but also create channels for incoming air.

The recesses in the bottom of the base can be made of a rectangular shape, but it is better to add to the original rectangle of the arc, to plot it using a CD

The housing we will collect, using a hot melt adhesive. The cooler must be located approximately in the central portion of the housing surrounded by the four rectangles forming the wall of the structure. Oil the glue along the perimeter of the cooler and its surrounding walls. Do not forget that the recesses in the walls, which we just cut should be in the lower part of the body.

Wires can be removed from the cooler design angle, securing them in this position, glue.

At this stage, it is best to install and connect. Since we are using the switch, we need to share one of the wires and form a chain. The wires should be connected to the power connector (red - plus, black - negative). If we make a mistake in the polarity, simply reversing the connection. With the help of hot melt adhesive anchoring connector and switch on the places designed for them.

Connect the power and check if the turbine is operating. If all goes well, we continue to build our bladeless model.

Take the ring A, which will be located in front of the unit, and a first strip (12h74sm). Closes the strip into a circle and glue in it to the inner circumference of the ring A. It turned similarity-cylinder without a top hat, but with the fields. The same must be done with the ring B and the second strip (12h82sm).

Here is a semblance of hats came out of the ring A and the first strip, which we pasted on the inner circumference of the ring

Glue the first "barrel" to the front side of the body a place where we cut segment. The second "cylinder" is also glued to the rear side of the housing cut surface. Thus a smaller "cylinder" is within the larger.

Stability can be given a structure with five strength partitions mounted between rings by means of the same adhesive. They need to be cut out of cardboard. partitions length should be slightly less than 12cm. Now, the main side surface design should close the remaining third strip of cardboard (15h86sm).

In this photo is well visible internal fan design, which will be hidden from us the last (third) strip

In principle, the fan is ready. It remains to give it a gloss. To do this, remove the excess glue and covered with paint or paste over the decorative paper of its outer surface.

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