Mole spinner from a plastic bottle: how to make a repeller for the garden

Gardens and vegetable gardens are a good help both in terms of food and in terms of relaxation for the soul. But everything that is grown on personal plots faces many dangers - beetles, larvae, birds, moles. And if chemicals help fight plant diseases or insect pests, then it is best to scare away birds and moles from the site, rather than destroy them. A primitive design will help with this - a windmill made from a plastic bottle, made with your own hands from scrap materials.

Repellers made from plastic bottles

A bottle placed on a pin is the design of the simplest repeller. The same structure can be made from empty beer cans. The pin must be stuck into the ground so that the vibrations from the repeller are transmitted into the thickness of the earth.

Interesting fact! An iron pin is much more effective than a wooden one, since metal transmits sound waves better.

A windmill against moles is a more complex design. To make it you will need a beer bottle with a capacity of up to one and a half liters.

It is important to know! A high-quality repeller can be made from an ordinary beer bottle with a narrow, elongated neck.

To make a windmill, you need to have some more tools, such as scissors, a marker, a self-tapping screw, a nail, an awl and a pin (stick). As a rule, there are no ready-made diagrams and drawings, since the device is quite simple. In addition, there is a video where you can clearly see, frame by frame, the methodology for making such a repeller.

You need to cut off the bottom of the bottle along the line that can be found on the bottle.
The cut bottom should be turned upside down, resulting in the shape of a five-pointed star. Use a marker to mark the areas to be cut. A section is cut out from the center of the bottom, both in the middle of the “star” beam and along the depressions located between the beams.
The same operation should be carried out on all rays. The result should be a kind of propeller. After this, a hole is punched in the center of the bottom. Since the product is intended for rotation, the hole should not have burrs. In addition, the diameter of the hole should be slightly larger than the diameter of the screw.
This propeller is screwed using a self-tapping screw to the bottle cap (the same one), and strictly in the center. To simplify this task, first make a thin hole in the lid. For reliability, the self-tapping screw is fixed on the inside of the lid with a kind of nut made of any material.
From the bottom of the bottle neck, 2 holes are made strictly opposite each other.
At the final stage, the windmill is taken and secured to a wooden stick, after which the entire structure is stuck into the ground where necessary.

Under the influence of wind force, the structure makes an unpleasant sound, which negatively affects moles. The advantage of the design is that the windmill turns automatically, depending on the direction of the wind.

To drive the mole away from the site, it is enough to make a simpler design. To do this, you need to take a plastic bottle and simply place it on a wooden stick. Below you can see what this design looks like.

You can enhance the effect of such a design if you bury a metal pipe in the ground at a level below the molehills. After this, a pin with a windmill is installed in the pipe. To prevent this pin from dangling, it is fixed in the pipe. It is better if the design works regardless of wind direction. To do this, special blades are cut into the sides of the bottle and bent outward.

Summer is the time for delicious berries and fruits. But there are still a lot of feathered thieves when ripening cherries or cherries, which can greatly spoil the harvest, to the chagrin of the owners. And such simple devices as turntables can help protect the garden from uninvited guests. Making them is easy and inexpensive, all the material is at hand, and decorating a garden or vegetable garden with budget pinwheels is also a good thing! So, arm yourself with the necessary tools and empty bottles - and get to work!

Deterrents - how do they work?

When analyzing methods of fighting moles, one cannot ignore repellents. With proper selection and application, they allow you to solve the problem in a few days with minimal effort in at least half the cases. Therefore, before moving on to more radical methods, it is worth trying to start with repellers.

As noted above, it is possible to scare away moles from the area using unpleasant odors and sounds. It is worth using both methods in combination.

As an option, it is worth considering sound repellers, made with your own hands from scrap materials:

turntables;
weather vanes;
alarm clocks;
bottles, etc.

Pinwheels are made from ordinary empty plastic bottles or cans. They are mounted on metal poles firmly fixed in the ground. When the wind blows, they begin to make loud sounds that enter the soil. Often moles are frightened by the turntables and leave the area. But it is impossible to say that a windmill for repelling moles is a one hundred percent effective remedy, because it does not always act as its manufacturers would like.

Weather vanes have a more complex design, which operate on the principle of turntables or, as an option, reed stalks that make a sound in the wind.

An interesting option is Chinese battery-powered alarm clocks. They are placed in ordinary glass jars, after which the device is buried in the ground in the expected habitat of the moles. You need to bury several jars with alarm clocks, with each one set at a different time, forcing them to go off one after another with minimal pauses.

Alternatively, you can use empty plastic bottles. They are simply laid out around the site in large quantities. Nighttime temperature changes cause the air to expand and contract, causing the plastic to crack, again irritating and frightening to animals.

The method of repelling moles using glass bottles is more than simple. They are buried in the ground at an angle of 45 degrees, leaving only the neck outside. Blowing into it, the wind will cause a sound to be produced that scares away moles.

All of the above means are installed near the expected mole habitat, focusing on the tunnels. The more repellers are used, the more likely it is that control methods will produce positive results.

The effectiveness of homemade scarecrows

Outwardly, moles look like cute and harmless animals. But at the same time, they can cause significant harm to the garden plot. Moles by nature are blind animals. Thanks to this, their hearing is highly sensitive.

Attention! Taking into account the special influence of sounds, the irritating effect of homemade devices is much more effective than in cases with other animals.

Accurate determination of the permanent habitat can be difficult because the family has several exits from the burrow. Therefore, determining its location is not easy. The task is further complicated by the fact that the depth of the hole can reach several meters. As a result, the right solution is to make homemade turntables from available or scrap materials.

DIY mole repeller

Since the task at hand is not to destroy the mole, but to evict it from a certain territory, for this purpose they use “noisemakers” rather than various kinds of poisons and chemicals. How to make a mole repeller with your own hands? In fact, it is not difficult and there are several types of noise structures.

DIY drip irrigation from plastic bottles

Materials from which this device can be made:

plastic bottles;
tin cans of various shapes;
ultrasonic and electronic devices;
electric alarm clocks.

The leading place among homemade repellers is occupied by those made of plastic.

The simplest device in the fight against moles for your territory is an ordinary plastic bottle placed on a metal pipe. Under gusts of wind, a plastic bottle makes an unpleasant sound and transmits vibration through the pipe. They can be heard in the animal’s underground passages and he really doesn’t like them. It should be noted here that wooden sticks are not suitable for these purposes, since they conduct sound worse than iron.

Windmill made from a plastic bottle

A complex option is a mole repellent in the form of a windmill. This is a kind of weather vane that works under any wind direction. When it gusts, it makes an unpleasant sound that scares away moles.

Windmill made from a plastic bottle

A mole spinner made from a plastic bottle is made as follows:

Take an ordinary beer bottle with a volume of one and a half liters. Its shape should be classic.
The bottle is turned over and the bottom is cut off with sharp scissors. As a rule, the classic bottle shape has a stripe near the bottom. It is along this that the cut is made.
The finished cut bottom is turned over with the outer side up and a marker or felt-tip pen is used to draw lines along which further cuts must be made. Or rather, remove some of the plastic. The bottom has a central circle from which five rays radiate. You need to make markings from the border of the circle to the middle of the beam. Also from the middle of the circle and in the middle of the depression between the rays. This piece in the form of half a beam must be cut out.
This manipulation is repeated with the remaining rays. And now the turntable is ready.
A hole is punched exactly in the center of such a propeller, which should be perfect, without torn edges.
A self-tapping screw is inserted into the pinwheel (the cap is directed inward) and screwed into the center of the bottle cap. Twist all the way until the thread runs out. To make the fixation more rigid, it is possible to add a nut on the reverse side.
On the neck of the bottle, strictly marking the center line, two holes are made for the nail. They must be against each other.

The windmill against moles with your own hands is almost ready. All that remains is to secure it to a pole and stick it into the ground.

To make the repelling stronger, take a metal pipe and dig it into the ground below the level of the mole's passages. A pole with a weather vane is stuck into it and secured firmly to prevent vibrations. The sound of a rattle, which is unpleasant to the mole's ears, will scare it away from the inhospitable area.

Tin repellers

Making it is quite simple. If you imagine the sound of metal regularly hitting metal, it becomes clear that it cannot be pleasant. The mole definitely doesn't like that sound.

Tin repellers

But it’s enough to stick a piece of rebar or any other “iron” stick into the ground and hang a beer can on it. Under wind gusts, the can will beat against the metal rod and the sounds of the blows will go deep into the ground. Such a musical performance will again force the mole to say goodbye to the garden.

You can also string any number of the same beer cans onto a rope. The main thing is that the distance between them allows them to knock against each other in windy weather.

How to make a mole spinner from tin cans? It is made similar to a pinwheel from a plastic bottle. Here the blades are cut out with scissors and bent outward. Despite its small size, such a repeller will be quite loud and will quickly drive the mole out of the area.

Attention! As for ultrasonic devices, people with some experience can make them themselves.

Those who want to have an ultrasonic mole repeller on their property should turn to professionals who have a good knowledge of physics and electronics. Because explaining to an amateur how to assemble such a device is not very easy.

Such devices create vibrations inside the soil. Only the mole and other underground inhabitants can hear them. The human ear does not recognize ultrasound noise. But the animal’s excellent hearing will immediately suffer. The mole will stop excavation work in this direction and turn the underground passage in the other direction.

Sound waves having an electronic source operate like all mechanical devices. Except that they are controlled by a certain circuit. Sometimes devices with electrical noise have a vibration motor that can increase the intensity of sound underground. You can purchase different types of ultrasonic devices against moles in specialized stores, but the cost may scare off ordinary summer residents.

Radical methods of struggle

If the methods listed above did not help, it’s time to radically change your actions. The moles must sense whose land it is. We must continue the fight with the help of:

ultrasonic device (bought at a garden center, runs on batteries within a radius of 15 meters);
mechanical mouse traps;
firecrackers (they are set on fire and thrown into passages);
rags soaked in gasoline (placed in the center of the hummock and covered with earth);
smoke screen (the newspaper is doused with machine oil, set on fire, and the mole is smoked out with smoke);
granular mineral fertilizers (filled inside the hole, buried with earth);
raw chicken egg (it will rot in the molehill and drive it out);
a zinc-based preparation;
chemical poisons from rodents;
exhaust gas from a running car engine.

Mechanical methods of mole control have proven their effectiveness in practice. Along the entire perimeter of the site, a mesh is buried to a meter depth, gravel is poured, boards and old linoleum are laid (whatever is found in the house). This will create a barrier. Will not allow the digger into the territory.

To protect the lawn from unwanted visitors, lay out a plastic mesh over the entire surface of the area allocated for it. The top is covered with drainage and soil. Even if a mole climbs into the area, it will not be able to lift a mountain of earth onto the grass - the net located below will interfere.

Mechanical methods will not drive away the underground guest, but they will not spoil the appearance of the landscape design.

Decorate the bottom of the pinwheel with electrical tape. So that the turntable can be hung, make a hole in the cork and insert the fastener into it. The spinner is ready!

A simple pinwheel made from a plastic bottle

Most often you can see a wind spinner, which is attached to a stick and has the shape of a screw. This pinwheel can also be made from a plastic bottle. To do this, also remove the label from the bottle and wash it well. Then, using a marker, divide the bottle into 5 equal parts - blades.

From the outside, close the hole with a lid that can be glued with a glue gun. Secure the pinwheel to a support and insert it into a jar. You can dig the pinwheel into the ground. All that remains is to paint and decorate the craft and the wind spinner is ready.

A mole is a seemingly harmless creature, but it can cause devastating harm to a garden plot. It lives in the ground and harms the root system of all plants growing in the country.

Gardeners constantly fight moles and use:

ultrasonic repellers;
poison food;
fall asleep in the holes where the mole comes out;

some resort to homemade traps. That's what we'll talk about. How to make a mole repeller with your own hands? Which are the most effective?

All repellers, including homemade ones, can be divided into types:

Mechanical, that is, the design contains parts that rotate, move, and create vibration, crackling, and noise. These mechanical actions repel moles;
Biological means capsules that contain aromatic oils, the smell of which pests cannot stand. In addition, this group can include plants that have an unpleasant aroma for bedbugs;
Electronic. This category of repellers includes purchased ones that operate on battery power or electricity. As a rule, these are vibration repellers;
Ultrasonic. The emitter of frequency sound waves repels small animals. When such sounds enter the ground, moles are alerted to danger.

With a wide variety of all kinds of repellers, homemade products bring no less positive results. And if you use them comprehensively, your garden will be free from mole rat attacks.

How to make a mole repeller from a plastic bottle

A plastic bottle, let's call it one and a half, is a universal item in the garden.

It makes an indispensable weapon against moles.

Option #1

Basic items needed to make a windmill:

powerful scissors;
plastic bottle 1.5 l;
marker;
stationery knife;
sharp awl;
self-tapping screw;
metal plates (washers) with a hole in the center;
stick.

The manufacturing process includes several stages:

Use a marker to make a mark on the bottom of the bottle. To do this, draw a strip along the bottom edge, which is located just above the bottom;
Using a knife, we cut off the curved bottom of the bottle along the rim;
In order for the spinner to rotate clockwise, you need to correctly mark the bottom of the bottle. To do this, use a marker to make the first line, which starts from the center of the bottom and then continues along the center of one of the convex parts. The next line is from the center along the concave part of the bottom. And so on we mark the entire lower part of the one and a half sheets;
Using sharp scissors, cut out unnecessary elements. It should look like a propeller, that is, if you cut out the first element, then cut it one after another;
When cutting “through one”, 5 elements should be removed;
In the resulting propeller, make a hole in the center with an awl. To do this, heat the awl;
Put a homemade washer on the self-tapping screw and insert it from inside the propeller. Next, put three of the same washers on the self-tapping screw;
We take the remaining part from the one and a half rack. Make a hole in the cork with an awl. We screw a self-tapping screw into this hole. Finally, you will attach the propeller to the bottle. We do not screw in the screw all the way. This is necessary so that the plates rotate freely;
Place the windmill on a support (stick);
Make two holes in the neck and insert a nail into them. Using the sharp part, hammer the nail into the cut of the stick.

The principle of operation is simple, the wind hitting the blades of the turntable moves it, and the largest part itself rotates around the nail. The washers, due to the free attachment of the propeller to the one and a half, create noise, thereby scaring off moles.

Option No. 2

To make a homemade product, you will need a half-length, a stick, and scissors.

We make wide cuts in the walls of one and a half sheets, and cut them from top to bottom;
From the resulting slots you need to make smaller ones perpendicular to the main one. One above and one below;
We bend the resulting elements in different directions. The blades are obtained;
We make a hole in the bottom of the bottle through which we put the resulting structure on a stick.

When wind hits the blades, the repeller begins to rotate and create sounds that moles do not like. These devices can be placed near the mole's hole.

Advice! If you get creative and catch an animal, then remember that they bite very painfully. Therefore, you need to protect yourself and wear thick gloves.

Option #3

All the items needed to make the structure will be the same; in addition, you will need a plate cut from the wide part of another one and a half sheet.

We make 15 cm long slits in the bottle;
Cut blades of approximately the same size from additional plastic;
Insert the resulting blades into the slots to form a propeller;
Make holes in the cork and bottom into which a metal rod is inserted and attached to the support.

Free rotation creates rustling noises and vibrations that frighten the mole, after which it moves to another safe place.

Option No. 4

Place sticks along the perimeter of the summer cottage. Moreover, in one place, nearby, you need to place several sticks on which empty one-and-a-half sticks are put on.

When the wind blows, the plastic will bang against each other, creating sounds that prevent the pest from approaching.

Waste material goes to work

Many, many different useful crafts can be made from so-called waste material. It’s also easy to get useful things for your garden plot and vegetable garden by applying your imagination and skillful hands to seemingly unnecessary things. Many different options for bird and mole repellers can be seen in various sources, some of them are quite complex, and some are primitive. It’s worth starting to create with the simplest designs. Plastic bottles, scraps of polyethylene pipes, a broken handle from a house mop, a used welding electrode, gift ribbons from already unwrapped gifts, toy bells or drink cans - anything can be used.

What danger do underground inhabitants pose when they find themselves on the territory of a garden plot?

However, no matter what the defenders of underground inhabitants say, their presence on the site causes enormous harm:

the animal actually feeds on insects, but their diet also includes earthworms, which, in turn, have a tremendous impact on soil fertility;
daily blasting destroys the root system of plants that act as an obstacle to the path;
distorts the external state of the site beyond recognition;
leaves behind passages that are subsequently used by mice, causing considerable damage to the crop;
mixes the lower heavy layers of soil with the most fertile ones, which promises a decrease in its quality characteristics;
a lawn spoiled by pits is very difficult to mow with a lawn mower;
digs up water runoff with piles of soil, which retains excess moisture;
acts as a carrier of diseases that can cause irreparable damage to human health.
Moles are not difficult to deal with

Paying attention to the fact that moles are family animals, you can be one hundred percent sure that after a while they will begin to multiply, and the damage caused will grow exponentially.

Living underground, animals do not limit themselves in any way to underground paths; they create countless tunnels, one after another. Like people, they expand their home: they provide it with a corridor, storage rooms, and emergency exits. Corridors.

Moles are extremely voracious, they destroy everything that appears on their way: larvae, earthworms, butterflies, frogs, small shrews. All that they were not able to swallow right away, they leave for the future, digging out new loopholes for the bins.

DIY repeller

There are many different schemes that are practically within walking distance. One of the simplest, but at the same time effective, circuits is based on an asymmetrical multivibrator.

To create an ultrasonic repeller with your own hands, you will need the following parts:

2 transistors;
3 resistors;
1 capacitor;
switch;
power supply unit of the “Crown” type;
piezo emitter (you can use a mechanism from a wristwatch);

The dimensions of the homemade device are also quite compact, like industrial designs. They easily fit into a shirt pocket, and the signal range is at least 1 m.

The generator is created from elements DD1.3, DD1.4, resistors R6, R7 and capacitors C5, C6. A device assembly consisting of resistors R3-R5, capacitor SZ, transistor VT1 and diodes VD1.VD2 allows you to increase the signal frequency to 80 kHz.

To increase power, a push-pull bridge amplifier made from transistors VT2-VT5 is used at the output pin of the DD1 microcircuit. A piezoceramic emitter BF1 is also attached here, which emits ultrasonic signals after pressing the SB1 switch.

Some components can be replaced with more effective ones. A homemade rodent repeller can be mounted with another emitter, for example, a car piezo siren. Also, you can do without a microcircuit at all, but in this case the number of transistors should be increased to 9 pieces. The cost of self-assembly will cost no more than 450 rubles.

The simplest skewer - DIY noise maker

The simplest thing is to make a pinwheel that, when rotated by the wind, creates noise. The vibration is transmitted to the ground through the stand and scares away the animals. Birds and reptiles also prefer to stay away from the unknown. It should be taken into account that “motley ribbons” indeed have a “quarrelsome” character and may be offended by an unwelcoming reception. For several days when dealing with snakes, it is better to wear secure shoes and trousers. Here is a master class on making a repeller from plastic bottles:

We mark 4-6 windows with a marker, evenly located on the side surface of the bottle. You need to choose a container with smooth sides.
We cut through three sides of the marked rectangles.
We bend the cut sectors, as shown in the photo.
In the bottom and cap of the bottle we drill a hole slightly larger in diameter than the thickness of the rod. Using pliers, twist two rings of copper wire onto the rod. It will serve as a stop for the bottom of the container. We place the workpiece on the rod.
We stick the rod into the ground not far from the place of the moles’ “crime”.
For reliability, we install repellers every 10m on the site.

Another option is to make a ratchet to repel pests in your summer cottage from a beer can. As follows from the photo, the design is approximately the same.

The jar will emit sounds of a different frequency, which may be useful in conjunction with already made repellers. It is also useful to simply place several beer cans on metal pegs stuck in the ground. They will add new sounds to the overall “symphony”.

Beer can protects the interests of the garden

We almost forgot about “wind instruments”. To control pests on the site, it will be useful to bury several glass bottles halfway into the ground. The wind will definitely whistle in their necks, which the pests will definitely hear.

A monument to a good drink and a mole repeller in one bottle

What is a wind turbine?

Maybe someone doesn't know this. But a windmill is a kind of structure that can convert wind energy into mechanical energy. Plastic turntables are beautiful accessories.

They are not capable of such feats, but their rotation can turn into relaxation energy. After all, sometimes it’s so nice just to look at a beautiful windmill. Its rotating blades soothe and relax. Therefore, every summer cottage is simply obliged to acquire such a windmill.

Options from plastic bottles

The simplest version of a homemade repeller is a bottle placed on a pin. Also suitable for empty beer cans. The pin must be stuck into the ground so that sound and vibration are transmitted to the wormholes.

On a note!
Iron transmits sound better than wood.

The most difficult option is a windmill against moles. To make it you will need a one and a half liter beer bottle.

Important!
The bottle must be of a “classic” beer shape. That is, with a narrow elongated neck.

In addition to the bottle, you need good scissors, a marker, a self-tapping screw with threads that do not reach the head, a nail, an awl and a windmill stick. Given the maximum complexity of creating such a mole repeller from a plastic bottle, there are no visual diagrams or drawings. There is only an extremely clear video.

The bottom of the bottle is cut off along the horizontal line that is found on all plastic bottles.
The cut bottom is turned over with the bottom up. The bottom has the shape of a five-rayed star. Using a marker, mark the areas that need to be cut out: from the border of the central circle strictly in the middle of the “ray” and from the middle of the central circle along the hollow between the “rays”. This part needs to be cut off. It turns out that half of the “beam” is cut out.
The operation is repeated on all “rays”. The propeller is ready. All that remains is to punch a hole strictly in the center of the circle. The hole should have perfectly smooth edges and a diameter larger than the provided screw.
Insert a self-tapping screw with the head “inward” into the resulting propeller and screw it into the center of the bottle cap until the thread runs out. To make screwing easier, you first need to make a small hole in the cap. On the inside of the cover, the self-tapping screw can be secured with a nut for reliability.
Make two holes for a nail at the bottom of the bottle neck, strictly along the center line. The holes must be strictly opposite each other.
Take an almost finished windmill and secure it to a wooden pole. Stick the pole into the ground in the garden.

When there is wind, the propeller makes a rather nasty noise, which moles are afraid of. The advantage of a windmill is that it will work in any wind direction. In fact, this is an ordinary weather vane.

It’s not difficult to make your life easier and drive the mole out of the garden. To do this, you need to make a pinwheel from a plastic bottle to scare away moles without any special frills, mounted on a pin. The diagram of such a turntable is below.

To enhance the effect, a metal pipe is buried in the ground below the level of the molehills. A pin with a mole ratchet is lowered into this pipe and the pin is secured in the pipe so that it does not dangle. The spinner works almost like a windmill, but depends on the direction of the wind. Sometimes the wind cannot rotate the repeller if the direction of the air masses is different.

Alarm clocks

Mole repeller from alarm clocks
It is very easy to make a mole repeller from ordinary cheap battery-powered alarm clocks. Alarm clocks are set at different times to ring and the clocks are placed in jars with screw-on lids. The lids are sealed and the jars are buried in different places in the garden. Moles cannot stand the sounds of the alarm clock constantly coming from underground and leave the area.

The second option with an alarm clock: place it in a half-meter pipe, buried vertically. Holes are drilled in the bottom of the pipe for better sound distribution. This is what the pipe looks like.

The alarm clock is attached to a wire so that it can be easily reached.

On a note!
Of all the mole repellers, alarm clocks are one of the most effective methods. The only better repeller is a radio and speakers, but this type requires special knowledge.

Step-by-step instructions for making a turntable

Learn the most popular method of making a mole pinwheel from a plastic bottle. The main stages of creating a craft are as follows:

Cut the bottles in half: use a construction or stationery knife, and be extremely careful when doing the work. For a windmill, use the top of the containers.
Using scissors, cut blades of the same size on the halves of the containers.
Carefully bend the cut blades at the base at an angle of 45 degrees, slightly smooth out the bent elements.
Use an awl to make holes in the center of the wings and lid.
The bead is strung on a wire.
The metal wire is threaded through the cap, the windmill, the second cap, the bead, the third cap, another blank, the fourth cap, the final bead.
At the end, use pliers to make a bend to secure the elements strung on the wire.

Remember that the more parts and blades a turntable has, the louder its sound from the wind and the more impressive its appearance. If you decide to create a large mole repeller, then follow these instructions:

Take a wooden block and make a hole in it: its diameter should be slightly larger than the diameter of the installation rod.
Secure the covers on four sides of the bar using glue or galvanized fasteners.
Cut oval windows on each side of the plastic containers.
Screw containers with holes made to the fixed lids: as a result, the slots should “look” to the sides, and not up.
Fasten the made structure to the pin, secure it on different sides with metal washers, and cover the top of the pin with a plug.

General structure of the weather vane

Different weather vanes differ in shape and material, but their general design remains unchanged over the years.

The windmill consists of the following parts:

The housing holds the rotating axis. For a metal structure, a pipe with two bearings is used. The body of a plastic bottle product can be an ordinary wooden block.
The protective cap is located on the axis. It is shaped like a cone and serves as an umbrella for the body, covering it from the rain. In addition, the cap serves as a limiter for the axle, holding it at a certain height.
The axis connects the weather vane to the hull. The upper part rotates on it due to the influence of wind. Make your own axle from a flat steel rod. Even a nail will do for a PET bottle.
The wind rose is a cross made of stripes or rods with fixed letters indicating the cardinal directions. By using the wind vane and arrows, the wind roses recognize the direction of the wind.
The rotating part is called a weather vane. It is she who indicates the direction of the wind according to the wind rose. For beauty, the weather vane is given the shape of a bird or animal. The simplest design is made with your own hands from PET bottles. The indicator of the weather vane is an arrow, and a counterweight is necessary for centering on the axis.

Using the same principle, a windmill is made from a plastic container. If there is no need to determine the wind direction, the wind rose can be excluded from the design. And the protective cap does not play a significant role due to the lack of bearings.

Advice! By making a weather vane from a plastic bottle to determine the direction of the wind, the design can be improved with a device for measuring the strength of gusts. The device consists of a metal plate suspended by a rope from a weather vane. A scale is installed nearby. When the plate is deflected, the wind force is determined on the measuring scale.

Electrical circuit and operating principle

The rodent (mole) repeller is assembled according to the electrical circuit diagram below and consists of only two simple logic chips, a transistor and several passive elements located on a printed circuit board. A distinctive feature of the proposed circuit is low power consumption (a set of three AA finger elements with a capacity of 1 A*h is enough for the entire season), which is due to the emission of an audio signal with a frequency of about 480 Hz for two seconds with a frequency of once every 32 seconds. In addition, this mode of operation of the repeller has a more effective effect on moles and increases the time it takes rodents to get used to the sound.

Structurally, the circuit consists of a clock generator assembled on elements DD1.1 and DD1.2 generating a frequency of about 480 Hz, a frequency divider on the DD2 chip, a logical signal adder on DD1.3, a key transistor VT1 and an audio emitter BA1.

The frequency of the rodent repeller clock generator is determined by the values of resistance R1 and capacitor C1. By decreasing or increasing the value of R1 or C1, you can accordingly increase or decrease the frequency of the emitted sound signal.

From the generator, a rectangular sound signal without changing frequency, through logic element DD1.3 and current-limiting resistor R4, is supplied to transistor VT1, turned on in key mode. In silent mode, a voltage close to zero is applied to the base of the transistor and the transistor is closed. In this mode, the current consumption of the rodent repeller is 0.1 mA. In the sound signal emission mode, the current increases to 22 mA. A simple calculation shows that when using batteries with a capacity of 1 Ah, the mole repeller will work for 9000 hours or 375 days.

The signal from the clock generator is also sent to the counting input (pin 10) of the frequency divider DD2. Based on a positive signal drop at pin 9 of the counter, logical zero changes to logical one. In order to ensure the emission of an audio signal with a period of 32 seconds, a logical unit is supplied from pins 15, 1, 2 and 3 through diodes to the 12 pin of logic element DD1.3, locking it. As soon as a logical zero appears simultaneously at pins 15, 1, 2 and 3 of DD2, DD1.3 will pass a signal from the clock generator to the base of transistor VT1 and BA1 will begin to emit sound.

The chain C2 and R2 is used to set the output voltages of the DD2 chip to zero. When supply voltage is applied to the circuit, capacitor C2 begins to charge and a supply voltage appears at its lower terminal, which is supplied to pin R of the microcircuit. When the charging process is completed, the voltage at its lower terminal will drop to zero and will no longer affect the operation of the DD2 chip. Resistor R3 is a load for diodes VD1-VD4, so that there is somewhere for the current to flow and to eliminate interference in the absence of voltage at pin 12 of the DD1.3 microcircuit. C3 serves to suppress interference that occurs during transient processes in microcircuits.

How to make a mole repeller from a plastic bottle

A plastic bottle is an indispensable universal item used to create various devices in the garden. It can be used to make an excellent weapon against moles, the so-called windmill.

Method No. 1

To make a windmill from a plastic bottle you need:

large scissors;
plastic container 1.5 l;
permanent marker;
awl;
stationery knife;
self-tapping screw;
metal plates with a hole in the middle (washers);
strong stalk.

The manufacturing process itself consists of the following steps:

Use a permanent marker to make a mark on the bottom of the plastic bottle. Draw a strip just above the bottom along the lower border;
Using a stationery knife, cut off the figured bottom of the bottle along the drawn strip;
In order for the spinner to rotate in a clockwise direction, you must correctly mark the bottom of the bottle. First, draw a line with a marker and draw it from the center of the bottom of the bottle to the center of any of the convex irregularities. Next, draw a line that goes from the center of the bottom and ends in the concave part. And thus we place markings along the entire bottom.
Use large sharp scissors to cut out unnecessary elements. The result is a device in the form of a propeller. We cut out the first element and then cut through one after another.
5 such parts should be removed;
In the resulting bottom, we pierce a hole in the center with an awl heated on the fire.
We put a washer on the prepared self-tapping screw and insert it from the inside of the propeller. Then we put three more washers on it;
Take the remaining element from the bottle. Use a heated awl to make a hole in the lid and screw a self-tapping screw into it. In this way, the propeller is attached to the plastic bottle. There is no need to screw in the screw all the way. The plates must rotate freely;
Attach the turntable to the support.
Two holes are made in the neck and a small nail is inserted into them, which is then hammered into the handle.

The principle of operation of such a windmill is simple: gusts of wind, hitting the propeller, begin to spin it, and the largest element of the turntable also rotates around the nail. The washers create noise, which scares away small pests.

Method No. 2

This method requires fewer items to be used. You will need a stick, garden shears and a bottle:

We make wide cuts in the walls of the plastic bottle from top to bottom;
From these holes we make two more smaller ones perpendicular to the main one. One above, the other below;
We bend the resulting elements to the sides, you should get blades;
We put the resulting mechanism on the support after making a hole in the bottom of the bottle.

The wind rotates the blades, creating noise that scares away moles. Such devices are usually placed near an animal's burrow.

Advice! If you do end up catching a mammal, it is worth remembering that it can bite painfully. To protect yourself from an unpleasant surprise, you should wear thick gloves or mittens.

Method No. 3

To build a structure for repelling moles, you will need elements from the second method, as well as a plate cut from the wide part of another bottle:

In a plastic bottle we will make slits 15 cm long;
From the additional part it is necessary to cut the blades for the propeller of approximately the same length;
The blades must be inserted into the holes to form a propeller;
You need to make several holes in the lid and insert metal rods into them. Then attach the device to the stick.

When rotating, a rustling sound is produced, accompanied by vibration. Hearing it, the mammal gets scared and feels discomfort, so it moves to another habitat.

Method No. 4

You need to stick sticks along the perimeter of the land, placing several supports in one place. beer cans on them .

When there is a gust of wind, the plastic or metal will bang against each other, creating noise that prevents the approach of a harmful mammal.

Method No. 5

This is a so-called electronic mole repeller . It is made from a hollow metal pipe. The scheme is like this:

The pipe is dug into the ground and an inexpensive electronic beeping part from a battery-powered alarm clock is placed inside;
At the top, the pipe is covered with cloth to prevent noise from reverberating throughout the surrounding area, and with a cut-off bottle to protect the structure from rain.

Design Basics

It is no coincidence that a device for scaring away birds or moles from a site has a very specific name “windmill”. The main force that makes the structure perform its function is the wind. The wind is blowing - the windmill is working. In order for such a repeller to work, it needs to catch air currents, which means it needs blades. If you set a goal, then making a windmill from plastic bottles with your own hands is quite simple. The most important part - the blades - is cut out of plastic. Moreover, the blades from the bottle will not need to be attached, because they are cut in place and simply bent. The remaining design elements will depend on the purpose of the windmill. Tools you will need for work:

stationery knife;
scissors;
universal glue;
hard wire;
beads with a hole for wire;
self-adhesive film or colored electrical tape.
