Make a powerful shocker. How to make a stun gun at home? Do-it-yourself stun gun from batteries, lighters and other items. Parts needed to assemble a stun gun

The requirements for such a device are usually rather big - a pocket shocker must be compact and have high power. Having made a stun gun with your own hands, you can also equip it with a built-in flashlight. Thinking about how to make a shocker with your own hands, you can additionally consider the location of the charge readiness indicator in it. It is also desirable that the manufactured device does not consume too much electricity and has a relatively simple design. As a flashlight, it is convenient to use not a lamp, but a white powerful LED that works through a resistor from a common power supply. It is also more convenient to provide a ready indicator with a small LED. It will be useful to have a fuse that will protect against accidentally pressing the discharge button in your pocket.

To make a high-voltage coil, it is necessary to wrap a ferrite rod with three layers of electrical tape, and wrap at least 5 layers of tape on top. Then the primary winding is made, which consists of 15 turns of wire with a diameter of 0.5 to 1 mm. The coils should lie in close contact with each other. Again, 5 layers of electrical tape and 6 layers of tape are placed on top. Further manufacturing involves the use of polyethylene, for which it is well suited ordinary package. It must be cut into strips corresponding to the coil in width and 10 cm in length. They are necessary for the secondary winding, consisting of 350-400 turns. The winding should also lie tightly and in the same direction as the first. Each wound row is insulated with two layers of tapes cut from the package. The top of the winding after the end is reinforced with adhesive tape in 5 layers.

Additionally, then 2 layers of electrical tape and at least 10 layers of adhesive tape are applied, and the side holes can be filled with silicone for reliability. The finished transformer must be checked for breakdowns; for this, current is supplied from the capacitor to the primary winding. If, after the formation of the arc, no breakdowns appear in the winding, everything is done correctly. In this case, you can start manufacturing the converter transformer. For this, a ferrite transformer is again needed, which can be purchased, or can be removed from power supplies of various equipment that has become unusable. All existing windings from such a used transformer must be removed; to facilitate this procedure, it can be placed in boiling water. The broken parts are connected with superglue, for performance finished product it won't affect.

The primary winding of the converter transformer, without which no do-it-yourself stun gun circuit can do, should consist of 12 turns and is carried out with a 0.8 mm wire. The finished winding must be insulated with 3 layers of electrical tape and 5 layers of adhesive tape. The secondary winding of the converter consists of 600 turns, and the wire is required with a diameter of 0.1 mm. The winding is carried out in rows, it is not necessary to make it a turn to turn, but even when doing it in bulk, you need to be as careful as possible. It is most convenient to make a row of 70 turns, each new row from the next is isolated with electrical tape in 4 layers. After the winding is completed, the halves of the ferrite are combined and tightly wrapped with tape or electrical tape. Stages of manufacturing transformers in production homemade stun gun the most complex and labor intensive.

To receive quality product need manufacturing spark gap so that the capacitor can give its charge to the primary winding of the coil. It can be made from an old fuse by removing the tin from its contacts with a soldering iron and carefully removing the wire inside. Instead of a wire, small screws are screwed on both sides, which should not touch in the middle in order to avoid a short circuit. The size of the gap between the screws regulates the frequency of the discharges that form between the electrodes. Installation of parts is carried out in any case of suitable size, for example, from an old shocker. It is advisable to additionally cover the high-voltage part of the circuit with silicone for safety reasons. As bayonets, you can use a fork with cut middle teeth, two small nails or screws.

For greater safety, the transformer can be placed in a suitable size cardboard box and pour completely hot paraffin. The box should have a margin in height, since the paraffin shrinks after cooling, and the excess can be removed with a knife after hardening. Paraffin for this is melted in iron utensils, but do not heat too much, since the whole work can be spoiled from hot paraffin. Experts recommend that the process be carried out in two stages - first, fill it with paraffin, and then expose it to a fan heater or any other heat source for 10-15 minutes. This will get rid of all air bubbles, which could be formed in the first pour. If it is possible to build Vacuum pump, it is better to use epoxy resin instead of paraffin.

In order to supply the finished shocker with a charger, you can use ready scheme from a flashlight on LEDs, where the switches have several positions. During assembly, the batteries are located at the rear of the case, and the power switch can be used as a fuse. Any model of 4-5 amps or more can be used as a switch. You can remove them from the fixtures that have become unusable. The lock button should also be high current, and have 2-3 positions. For a flashlight, you can connect from 1 to 3 LEDs, this lighting is usually enough for a night road. After all the parts are mounted in the case in their places, you need to check the circuit for serviceability again. Then, to check the power, an ordinary incandescent lamp is placed between the bayonets, which, when correct work should light up from the discharge.

For any person, the issue of protecting oneself and loved ones is quite acute. And although the market offers many options for solving it, not every one of them can suit, and this entails the need to look for ways to resolve it on your own. One of the good options for ensuring your own safety is an electric shocker, which other craftsmen manage to make in artisanal conditions.

The concept of "stun gun"

A stun gun is called a special electrical appliance, used as a weapon of self-defense to stop or render harmless an attacked person or animal by applying an electrical discharge high power. Such a discharge causes numbness of the aggressor's muscles and a strong pain effect, which paralyzes the attacker for a while. Release this device different forms, capacity and price category. Persons are allowed to purchase and carry with them a stun gun with a power of up to 3 W upon reaching the age of majority, and no additional documents, certificates or permits are required. More powerful devices are intended for special services.

The most reliable are, of course, factory-assembled devices, but people who are well versed in radio engineering can try to make a stun gun with their own hands, since there are plenty of manuals and schemes, and get the right details also not difficult.

Parts needed to assemble a stun gun

The main part of the device is a voltage converter, made in accordance with the blocking generator circuit. In this case, one field-effect transistor with reverse conductivity of the brand IRF3705 is used (you can take the transistor IRFZ44, IRFZ46, IRFZ48 or IRL3205). It is also necessary to ensure the presence of a 100 ohm gate resistor with a declared power of 0.5-1 W, high-voltage capacitors with a capacitance of 0.1-0.22 uF (for serial connection two capacitors of 630 V each) and with an operating voltage above 1000 V, a spark gap (industrial or handicraft made from two pieces of wire 0.8 mm thick located one above the other, with a gap of 1 mm), a KTs106 rectifier diode. If you have all the necessary constituent elements, the task of how to make a stun gun will not cause difficulties for a real craftsman.

How to make a transformer

To assemble the converter, you need to properly make its main component - a step-up transformer. To do this, take, for example, a core from a switching power supply. Carefully freeing it from the old winding, carefully wind the new one. The primary winding is made with a wire with a diameter of 0.5-0.8 mm, applying 12 turns and moving away from the middle (6 turns are wound, the wire is twisted, 6 more turns are made in the same direction). Then you need to isolate it with transparent tape, making it 5 layers. A secondary winding is applied on top, having made 600 turns with a wire with a diameter of 0.08-0.1 mm, applying two layers of adhesive tape for insulation every 50 turns. This will protect the transformer from breakdowns. Both windings are made strictly in the same direction. For better insulation, you can fill the entire structure with epoxy. To the conclusions from the secondary winding, you need to solder a wire with stranded insulated wires. The resulting transistor is recommended to be placed on an aluminum heat sink.

The procedure for assembling a homemade stun gun

After the converter is manufactured, it is tested by assembling a circuit that does not include a high-voltage part. If the transformer is assembled correctly, the output will be a "burning current". Then solder the voltage multiplier. Capacitors are selected with a voltage of at least 3 kV and a capacity of 4700 pF. The diodes in the multiplier are high-voltage, KTs106 brands (such are in multipliers from old Soviet TVs).

By connecting the multiplier with the converter according to the scheme, you can turn on the resulting device, the arc should be 1-2 cm with the characteristics observed, and quite loud clicks with a frequency of 300-350 Hz are heard.

Lithium-ion can be used as a power source battery, how in mobile phones(their capacity must be at least 600 mA), or nickel batteries with a voltage of 1.2 V. The capacity of such batteries should be enough for two minutes of continuous operation of the device with an output power of up to 7 W and a voltage on the dischargers of more than 10 kV.

The circuit is mounted in some suitable plastic case, covering the high-voltage section of the circuit with silicone for reliability. As bayonets, you can use a cut fork, nails or screws. The circuit must also contain a switch and a momentary button so that there is no accidental self-closing. As can be seen from the above, the assembly of high-quality, reliable and powerful device requires quite serious skills, therefore, first of all, people who are versed in radio electronics should think about how to make a stun gun on their own.

How to make a stun gun from a battery

If you need a simpler way to assemble a stun gun, then you can literally make it from improvised radio components. To do this, you will need: an ordinary nine-watt battery of the Krona type, a converting transformer (you can take it from a power adapter or charger), an ebonite rod 30-40 centimeters long. Do-it-yourself stun gun is assembled as follows: two pieces of steel wire about 5 cm long are attached to the end of the ebonite rod with electrical tape, connected by wires to a converting transformer and a Krona battery. At the same time, the battery is connected to the two-pin terminal of the transformer (where the current is 6-9 V). A small push-button switch is attached to the other end of the rod, when pressed, a high-voltage arc appears between the steel antennae (it jumps at the moment when the circuit with the battery in the small winding opens, that is, to create a visible arc, you need to press the switch 25 times per second ). Despite the high voltage created in this design, the current strength will be very small, so such a stun gun can become more of a deterrent than protection.

How to make a stun gun from an electric lighter

If you know how to make a stun gun, then a small low power device intimidation can also be collected using a simple electric lighter to gas stoves. How to make a mini stun gun with it is described below.

In addition to the electric lighter itself, you will need a metal clip and glue, as well as a soldering iron, and everything you need for soldering. First of all, it is disassembled and the tube is cut off with the help of a cloth for metal, leaving only a handle with two wires sticking out. They are bitten with wire cutters to a protruding length of 1-2 cm. Having exposed the wires and treated them with a flux, two pieces cut from a metal clip are soldered to them. The antennae are slightly bent with wire cutters and glued to isolate the entire finished structure adhesive in front. Such a shocker is low-powered and is not suitable for serious self-defense.

Stun gun from electric lighters for gas stoves

Knowing the device electric lighters and more or less understanding radio engineering, you can understand how to make a stun gun out of a lighter. To do this, you need to take four electric lighters (more precisely, high-voltage coils and converter boards), three finger batteries or a battery, a flashlight housing or a tube with a diameter of 25 mm. Craftsmen offer to connect these parts together, add arresters and a switch to the circuit, which will allow you to assemble a stun gun with your own hands without special trouble. Each of the transformers is connected to two separate contacts, and all the contents are placed in a plastic case. It is assumed that with this method of assembly, four flashes should be obtained simultaneously on the arresters.

Film camera stun gun

To figure out how to make a stun gun with your own hands, you can think of an old unnecessary film camera - a “soap box”. It can be converted into a device that produces one-fourth of the energy of a professional shocker. To do this, you need to unscrew the camera, remove the batteries and find a small flash bulb. After that, it is disconnected from the wires, and two pieces are attached to the place of the flash to these wires. copper wire- with a thick layer of insulation and a length of 8-10 cm - by soldering. It is necessary to ensure that these wires protruding from the camera do not touch. The batteries are put in place, and the camera body after the manipulations is isolated with some kind of plastic coated so that only the dischargers in the form of copper antennae and the flash and shutter buttons are visible from it. Now, by releasing the shutter, you can get sparks on the arrester wires.

Thus, there are several ways to make a stun gun at home, it all depends on knowledge in radio engineering, skill and the available source material. When working, be sure to observe safety precautions, since the work is mainly associated with electric current. high voltage and power.

What is the most important thing in a person's life other than family happiness, secured existence and realization of their own ambitions? Naturally, personal security and self-confidence. Of course, it’s good to be sure when you are under two meters tall, have an oblique fathom in your shoulders, and you are fluent. And what about those who do not have such wonderful physical data. To do this, they came up with one very effective fixture called a stun gun. Today we will try to assemble a stun gun with our own hands. It turns out that there is nothing complicated in this self-defense tool. You can make a stun gun with a minimum knowledge of electrical engineering, but a maximum of diligence, however, as with the creation of any other makeshift weapons. I want to warn you right away that I did not assemble this device myself, I found the assembly instructions on the Internet and posted it on the site purely for informational purposes. So I can't vouch for the accuracy of the information. If someone finds errors in the device, please unsubscribe in the comments, we will fix it.

So for electroshock device assembly, we will need:

converter
capacitor
arrester
transformer

The principle of operation is quite simple: the igniting capacitor gives a discharge to a pair of arrester-transformer and a combat capacitor, as a result, a rather powerful electric pulse is obtained at the output.

Let's start with the manufacture of the converter transformer. We need a B22 core made of 2000NM ferrite, on which we need to wind a thin enameled wire with a diameter of 0.1 mm. This device is similar to a bobbin from sewing machine and can be purchased at an electrical supply store.

We wind until 1.5 millimeters remain to the edge. You should get five, six layers of winding. Between each layer you need to lay electrical tape. Then we completely wrap everything with electrical tape in a couple of layers and make the winding with a thicker wire with a diameter of 0.9 mm. Somewhere on the third layer we make a layering and wind the remaining turns. We connect the bobbin covers and wrap everything again with electrical tape.

Now we are waiting for the manufacture of a more complex part - the output transformer. We buy a polypropylene tube with a diameter of 20 mm in a plumbing store. Cut off a piece five centimeters long. Now we need to make a frame out of it, for this we insert a bolt suitable for the diameter of the tube into the drill, wind tape around it and put it into the tube. In place of the cutter, you can use a metal file or sharpened steel plastic. We machine grooves two millimeters deep and wide, but carefully so as not to cut through the tube. Then with a knife we cut a groove along the entire tube with a width of two, three millimeters.

Now we need a ferrite rod with a diameter of ten millimeters and a length of fifty millimeters. It can be taken from the line-scan transformer of an old TV. We break off the pieces we need from it and glue them together to make a rod right size. You can process it to a round state on sandpaper. However, you can buy ferrite rings in the store and glue them together with superglue.

We wrap the rod with a layer of electrical tape and wind a wire of 0.9 millimeters on it, stepping back from the edges of 5-10 millimeters. Be sure to wind it in the same direction as on the tube sections. Next, we isolate it with electrical tape, but so that the rod with the winding can freely enter the tube. We insert the rod into the tube from the side where there is no wiring output, and connect the two windings together. The result should be three outputs: the end from the first winding, the common connected end and the HV output. The winding phases must be in the same direction. Next, we put the transformer in a cardboard box and fill it with paraffin.

The figure below shows a diagram of a stun gun.

The ignition capacitor is charged through the bridge, and at the same time the combat capacitor is charged through the diodes. Diodes are needed to separate the capacitor circuit into two different ones.All parts used in the circuit can be bought at the store and placed on a 40X45 mm board.

You will need:

transistors IRFZ24; IRL2505
Resistors
3300 peak capacitor
batteries 6 pieces NicD size 1/2 AA

Now let's start the assembly process.The case of the stun gun can be made of cardboard.We insert the “insides” of the shocker there and fill it with epoxy.

I did not describe in detail the entire assembly process, because everything that is needed is indicated in the diagram above. Those who can understand such diagrams and hold a soldering iron in their hands will easily cope with the task even without these "valuable" instructions, those who do not ... well, they are unlikely to succeedmake your own stun gunand it is better to buy it in the store.

After the epoxy has hardened, you can proceed to testing a homemade stun gun on annoying neighbors (joke)

Defend in closed space from an unexpectedly attacked person is quite difficult. For example, how to stop a robber in an elevator? or they can hurt themselves, and a knife or a gun can become a deadly weapon. They will also give you a deadline.

So the best option will become, which, by the way, can be made independently. And today we will tell you how to make ordinary and powerful mini stun guns at home.

Before moving on to special types devices, let's talk about how to make the simplest stun gun.

Necessary equipment and raw materials

Here is the list necessary materials and details:

silicone;
insulating tape;
a ferrite rod pulled out of an old radio;
plastic bag;
scotch;
wire;
wire with a diameter of 0.5 to 1 mm;
wire with a diameter of 0.4 to 0.7 mm;
wire with a diameter of 0.8 mm;
ferrite transformer pulled out of impulse block power supply of any electronic device;
fuse;
battery for power supply;
diodes, capacitor and resistor for the charger;
Light-emitting diode;
switches;
an old suitable case or plastic for its manufacture.

And now we will learn how to make a homemade stun gun.

Creation technology

High voltage coil

First, we make a high-voltage coil.

To do this, we wrap a ferrite rod about five centimeters long with three layers of electrical tape, then fifteen turns of the thinnest wire go.
On top - five more layers of electrical tape and six layers of adhesive tape.
We cut the plastic bag into strips ten centimeters long and a width corresponding to the length of the coil.
Next comes the secondary winding with a thicker wire (from 350 to 400 turns) in the same direction as the primary winding.
We isolate each row of wire (from 40 to 50 turns) with polyethylene tapes and five rows of adhesive tape.
At the end are two layers of electrical tape and ten layers of tape. Fill the sides with silicone.

converter transformer

Now we make the converter transformer.

Its basis will be a ferrite transformer, from which you need to remove all the windings and the ferrite frame (you may have to put the part in boiling water for a while).
We wind the primary winding from a wire 0.8 mm thick (12 turns). The secondary winding is 600 turns (70 turns in a row) with millimeter wire.
To isolate each row, lay four layers of electrical tape. Having inserted the halves of the ferrite, we fix the structure using electrical tape or adhesive tape.

spark gap and other parts

The next detail is the spark gap.

For it, we take the old fuse, remove the tin on its contacts with a hot soldering iron, and pull out the inner wire.
We screw the screws on both sides (they should not contact).
By changing the gap between them, you can change the frequency of discharges.

We take ready-made batteries:

lithium-ion (pulled out of a mobile phone),
nickel-cadmium or lithium polymer.

The latter are very capacious, but they must be bought, and this is expensive.

For the charger, we solder a diode bridge, a capacitor, a resistor and a signal LED. A diagram with the characteristics of parts can be found on the Web. Charging time will be about three to four hours.

As for the body, you can find something suitable by gutting faulty device. Or glue it from plastic parts. You can even make a case out of cardboard by filling it with epoxy. The result is a stun gun with a power of about five watts, consuming up to three amperes of current. Remember that more than three seconds a person should not be affected by a discharge.

Special types of homemade EShU

From a flashlight

So, how to make a stun gun from a flashlight like the so popular ones, or, for example,?

It will take, in fact, only the body of the flashlight - the LED can also be left. This is convenient because there are already batteries inside.
There should also be placed four high voltage coil and converter pulled out of electric lighters for gas stoves.
Spark gaps and a separate switch are added to the circuit.
Each transformer has its own two contacts.
Arresters are made from steel narrow strips or pieces of paper clips.

We will tell you how to make a stun gun from a battery.

From a battery

This is the easy way. For him you will need:

battery type "Krona" with a capacity of 9 watts;
ebonite rod from 30 to 40 centimeters long;
converting transformer (ready-made, pulled out of the charger or AC adapter);
insulating tape;
steel wire;
push button switch.

We take an ebonite rod and attach two five-centimeter pieces of steel wire to it with electrical tape. They need to be connected with a wire to a transformer and a battery. The switch is attached to the opposite end of the rod. When you press its button, a discharge (arc) will appear between the pieces of wire. To do this, you need to press 25 times per second.

The power of the device is small - it can be used more for intimidation, and not for protection.

From a lighter

So, how to make a stun gun from a lighter? We will need:

battery operated electric lighter;
clip;
glue;
soldering iron and solder.

We disassemble the lighter, cut off the tube with a hacksaw. We only need a handle with wires coming out of it. We leave them a length of one or two centimeters, cutting with wire cutters. Then we expose their tips and solder pieces of paper clips there. The ends are slightly bent. We fix the whole structure with glue. The power of the device is also not too high.

The video below will tell you how to make a stun gun from a lighter at home:

In the form of a pen

You will need:

a small carnation;
two lighters (one with a piezoelectric element);
handle with a button and a metal clip, having enough large diameter, containing the piezoelectric element;
hacksaw for metal;
glue gun.

We disassemble one of the lighters and take out the piezoelectric element.
We disassemble the handle, pull out the inner plastic sleeve and cut out its middle part to a length corresponding to the size of the piezoelectric element.
We remove the clip and on the side with a heated (second lighter) carnation we make a hole in the upper part of the handle body.
With a hacksaw we make an incision for the wire.
We put the handle button in place, glue the insulation of the piezoelectric element wire with a thermal gun and glue it to the second part of the plastic inner sleeve.
We insert everything into the body of the handle, bring the wire into the hole, then pass it along the sawn groove and clamp it with a metal clip from the handle.
We insert the lower part of the sleeve and assemble the handle.
Now, when you press the button from the clip, it will shock.

But this is more of a toy than a means of self-defense. And now let's find out how to make a stun gun from a capacitor at home.

From the condenser

We take a capacitor from a long lamp daylight. He earlier in Soviet times, was rectangular, red or green. AT modern models it is a white cylinder.

We also need a wire (double) with a plug at the end. The length of the wire can be left about ten to fifteen centimeters.

We expose the ends opposite to the plug, fasten them to the capacitor contacts and carefully isolate them. That's it. Now, after charging from the network, a discharge will appear at the ends of the plug, quite noticeable. But it does not bring harm - it only pinches.

About how to do powerful stun gun at home, the video below will tell:

Specifications homemade stun gun
- voltage on the electrodes - 10 kV,
- pulse frequency up to 10 Hz,
- voltage 9 V. (Krona battery),
- weight no more than 180 gr.

Device design:

The device is a generator of high-voltage voltage pulses connected to the electrodes and placed in a housing made of a dielectric material. The generator consists of 2 series-connected voltage converters (Scheme in Fig. 1). The first converter is an asymmetric multivibrator based on transistors VT1 and VT2. It is turned on with the SB1 button. The load of the transistor VT1 is the primary winding of the transformer T1. The pulses taken from its secondary winding are rectified by the diode bridge VD1-VD4 and charge the battery of storage capacitors C2-C6. The voltage of capacitors C2-C6 when the SB2 button is turned on is the power supply for the second converter on the VS2 trinistre. The charge of the capacitor C7 through the resistor R3 to the switching voltage of the dynistre VS1 leads to turning off the trinis VS2. In this case, the battery of capacitors C2-C6 is discharged onto the primary winding of the transformer T2, inducing secondary winding high voltage pulse. Since the discharge is oscillatory in nature, the voltage polarity on the C2-C6 battery changes to the opposite, after which it is restored due to overdischarging through the primary winding of the T2 transformer and the VD5 diode. When the capacitor C7 is recharged again to the switching voltage of the dinistr VD1, the trinistor VS2 is turned on again and the next high voltage pulse is formed at the output electrodes.

All elements are installed on a foil-wrapped fiberglass board, as shown in Fig. 2. Diodes, resistors and capacitors are installed vertically. The case can be any suitable size box made of a material that does not transmit electricity.

The electrodes are made of steel needles up to 2 cm long - for access to the skin through human clothing or animal hair. The distance between the electrodes is at least 25 mm.

The device does not need adjustment and operates flawlessly only with correctly wound transformers. Therefore, follow the rules for their manufacture: transformer T1 is made on a ferrite ring of size K10 * 6 * 3 or K10 * 6 * 5 from ferrite grade 2000NN, its winding I contains 30 turns of PEB-20.15 mm wire, and winding II - 400 turns of PEV-20.1 mm. The voltage on its primary winding should be 60 volts. The T2 transformer is wound on a frame made of ebonite or plexiglass with an inner diameter of 8 mm, an outer diameter of 10 mm, a length of 20 mm, and a cheek diameter of 25 mm. The magnetic circuit is a segment from a ferrite rod for a magnetic antenna 20 mm long and 8 mm in diameter.

Winding I contains 20 turns of PELSh (PEV-2) wire - 0.2 mm, and winding II - 2600 turns of PEV-2 with a diameter of 0.07-0.1 mm. At the beginning, winding II is wound on the frame, through each layer of which a layer of varnished fabric is placed (a breakdown between the turns of the secondary winding may necessarily occur otherwise), and then the primary winding is wound on top of it. The conclusions of the secondary winding are carefully insulated and attached to the electrodes.

The list of necessary elements for self-assembly stun gun:
C1 - 0.047uF;
C2 ... C6 - 200uF * 50V;
C7 - 3300pF;
R1 - 2.7 kOhm;
R2 - 270 MΩ;
R3 - 1 MΩ;
VT1-K1501;
VT2-K1312;
VS1-KH102B;
VS2 - KU111;
VD1...VD5 - KD102A;
VS1 and VS2 - P2K (independent, fixed).

Application:

In case of a perceived threat to your safety or in advance, press the VS1 button, after which the device starts charging, at this time there is no voltage on the electrodes yet.

After 1-2 minutes, the electric shock will be fully charged and ready for use. The ready state is maintained for several hours, then the battery is gradually discharged.
