How to make a stun gun yourself at home: a few easy options. Homemade stun gun. Instructions and diagram how to assemble a stun gun with your own hands How to make a safe stun gun

Every man is concerned about the safety of the people he loves. Firearms and airguns are not always available, nor are they safe. Only electroshock devices help out, which for several decades have been considered the safest and most reliable means for personal self-defense. By tradition, today we will assemble a low-power and compact stun gun, which is more suitable for ladies.

The power of such a homemade stun gun is not great - 5 watts, but compared to 3 watt store-bought stun guns, our copy is in the lead.

You can take any case itself, I cut it off chinese lantern under the right dimensions, it was there that he mounted the entire circuit. The stun gun is made according to the traditional scheme using a high-voltage coil.

The inverter is built on just one powerful field-effect transistor, the circuit is better known as a blocking oscillator. The gate resistor can be selected with a nominal value of 40-820 ohms.

I used an assembly of 4 as a power source nickel cadmium batteries with a capacity of 350mAh, their total voltage is 4.8 volts. The capacity of such a battery is quite enough to obtain the declared power.

The converter transformer is wound on a W-shaped core, it is on the same core that transformers are wound from power supplies for halogen lamps low power (up to 50 watts). First you need to carefully disassemble the transformer so as not to damage the core. Then remove all factory windings and wind a new one.

The primary winding contains 2x4 turns of wire 0.6-0.8 mm, we put insulation on top with 6 layers of thin, transparent adhesive tape and wind the step-up winding.
The secondary (step-up) winding consists of 650 turns, wound in layers, each layer consists of 70 turns. Try to wind the coils as carefully as possible (coil to coil is not necessary, just be careful).
Each row of winding is insulated with 4 layers of the same adhesive tape. The finished transformer does not need to be poured epoxy resin.

The high voltage coil is the main part of our circuit. The coil is wound on a ferrite rod (any brand) with a diameter of 6-8 mm (not critical). To begin with, the rod must be carefully insulated with adhesive tape, electrical tape and other insulating materials.

The primary winding is wound with a wire of 0.7-0.8 mm and consists of 14 turns, then you need to isolate the winding with 10 layers of adhesive tape and wind the secondary.
The secondary contains 500 turns of 0.1mm wire and is also wound in layers - 70 turns per layer. Interlayer insulation is laid with the same adhesive tape. The finished transformer is placed in a syringe (of a convenient diameter) and filled with epoxy. You can do without pouring, but for reliability it is advisable to fill it, especially if you are winding high-voltage transformers for the first time.

High-voltage capacitors with a capacity of 0.1-0.22uF, I put two capacitors in series (each 630V 0.22uF). You should pay attention to the voltage of the capacitor, only those with an operating voltage of 1000 volts and above are suitable.

Spark gap - through this spark gap, the capacitance of the capacitor is discharged to the primary winding of the high-voltage coil. I made the arrester from two pieces of 0.8mm wire located one above the other, the distance between them is 1mm (you may have to play with the gap). You can also use industrial arresters with a breakdown voltage of 700-900 volts.

The switch has three positions - the middle point - and the flashlight and stun gun are off, top point- the shocker is on, the lower point - the flashlight is on.

Flashlight - made of 4 white ultra-bright LEDs connected in parallel (removed from a Chinese LED flashlight). The FET can be replaced with IRFZ40, IRFZ46, IRFZ48, IRF3205, IRL3705 or similar.

Rectifier diode - KTs106 with any letter or three diodes connected in series with a reverse voltage of at least 1000 Volts (for each diode), diodes must be taken pulse or fast diodes (FR107 / 207 are suitable from pulse, UF4007 is great from ultrafasts).

The device can be ordered. Write to

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 self-defense weapon to stop or render harmless an attacking person or animal by delivering a high-powered electrical discharge. 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) and with an operating voltage above 1000 V, 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 secondary winding you need to solder the 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 Krona-type battery, 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.

Powerful electric shock do-it-yourself 100 W

The do-it-yourself electric shock can assemble almost any ham radio at home. Peak The power of this model reaches 135 watts.- and this is an absolute power record for such dimensions. The shocker turned out to be quite pocketable, has enough stylish design thanks to the coating of 3D carbon fiber (in the store, a meter of such carbon costs about 4 grams. The shocker itself is made in a case from a Chinese LED flashlight, of course, I had to tinker with reworking the case. simple design and weighs no more than 250g.

Device Diagram:




It all started with the eBay auction two sets of lithium-polymer batteries with a capacity of 1200mA at a voltage of 12 volts were ordered (according to the passport 11.1 volts). The short circuit current of such batteries is over 25 amperes. But for such batteries it is a sin not to make a powerful converter. Without thinking twice, a circuit of a powerful high-voltage inverter 12-2500 Volts was assembled.

The circuit is built on powerful N-channel field switches of the IRFZ series48, but the choice of transistors is not critical. Later, the transistors were replaced with more powerful IRF3205, it was thanks to this replacement that the power was increased by 20-30 watts.

The 5kV 2200pF capacitor used in the multiplier can deliver power of 0.0275 J / s, there are 4 such capacitors in the multiplier.
Sufficiently large losses in the converter, in the inductor and in the diodes of the multiplier.

Output voltage - 25-30kV
Maximum power - 135 watts
Long-term power - 70 watts
Discharge frequency 1000-1350Hz
Distance between output contacts - 27mm
Power - battery (LI-Po 11.1V 1200mAh)
Flashlight - has
Fuse - has
Charging - transformerless, from a network of 220 Volts
Weight - no more than 250g

Transformer - was taken from a Chinese electronic transformer for powering halogen lamps with a power of 50 watts.
It is necessary to remove all regular windings from the transformer in advance and wind new ones.



The primary winding is wound 5 cores at once copper wire, each of the cores has a diameter of 0.4-0.5 mm. Thus, in the primary winding we have a wire with a total diameter of about 2.5 mm.



First you need to cut 10 pieces of the specified wire, the length of each piece is 15cm. Next, we assemble two identical tires of 5 turns.
We wind the primary winding with two tires at once - 4-5 turns around the entire frame. Next, we cut off the excess wire from the ends of the windings, remove the varnish, twist the cores and tin them.



Next, we isolate the primary winding with 10-15 layers of ordinary transparent tape and start winding the secondary (step-up winding)
The winding is wound in layers, each layer has 70-80 turns. This winding is wound with a wire of 0.08-0.1 mm, the number of turns is 900-1200.

Interlayer insulation is made with the same transparent adhesive tape, for each row we lay 3-5 layers of insulation.
The finished transformer cannot be turned on without load; it does not need to be filled with resin.


high voltage part

voltage multiplier. High-voltage diodes of the KTs123B series are used here, you can replace them with KTs106G or any other high-voltage diodes with a reverse voltage of at least 7-10 kV and with an operating frequency of more than 15 kHz.


The finished multiplier is poured with epoxy resin directly in the EShU housing.



The exit bayonets are made of solid stainless material, the distance between them is a little more than 25mm. You should not spread the bayonets for a long distance, although the air breakdown can reach up to 45mm.


The switch and button must be selected with a current of 3 A or more. The LEDs for the flashlight were taken from a Chinese lamp, the usual super-bright ones.
They are connected in series, power is supplied through a 10 ohm 0.25 watt limiting resistor.



Charging is performed according to a transformerless circuit, the output voltage is 12 volts at a current of 45 mA. Now many will think that it is unthinkable to charge such batteries with this charger, but the current is negligible, it takes a long time to charge, but the batteries do not swell, besides, the circuit is simple and works stably, does not heat up and is not afraid of a short circuit. Of course, if possible, it is advisable to use a normal charger to charge such batteries, but in my case there was no such possibility.



Our shocker is dozens of times more powerful than industrial ESH models that can be found in stores, even the famous scheme of Pavel Bohun (EVIL SHOCKER) in front of this device is just a toy.

Well, on this note, we will conclude our article, the shocker came out good, has a super high power, but has not yet been tested on people, but with such a device you can safely walk the streets of even the most dangerous areas.

Ensuring human security plays an important role, it is for this reason that many choose various means protection. Pneumatic or, for example, firearms are not always available, and also unsafe. The stun gun belongs to the means of self-defense for which a license is not required. For this reason, this type of protection has been quite popular for many years.

The choice of such devices is now quite wide, but you can make a stun gun with your own hands. The diagram below will help you quickly and easily understand everything. Homemade stun gun does not pose any danger to others and can only be used for self-defense. In the article we will talk about what this device is, how it works. In addition, we will tell you how to do what features of its use.

Types of stun guns

Modern factory stun guns are various kinds. Outwardly, they may different sizes, differ in power and even have a body in the form of items such as a flashlight, pen, gun, lipstick etc. The device can be powered by batteries or a rechargeable battery. Batteries are installed in less than powerful models. Sparking in a stun gun can be low or high frequency. Devices with a frequency of 50-80 Hz cause pain in the first second, but do not cause severe harm. As a rule, they can only scare. Devices with a frequency of more than 100 Hz allow you to temporarily neutralize the attacker. Stun guns differ from each other in that low-frequency ones emit a crackle, high-frequency ones buzz. You can also independently determine which stun gun is in front of you by experience: more powerful devices can set fire to paper.

Such devices are used for self-defense in order to neutralize the attacker by applying an electric discharge. The stun gun creates a strong pain effect and acts on the muscles, paralyzing the attacker for a certain time. Use this device allowed only to persons who have reached the age of majority. To purchase a stun gun in a specialized store or to make it yourself - everyone decides individually. Buy finished device quite costly, but simple. There is Alternative option- try to make a stun gun with your own hands. The scheme of such a device clearly shows what we will have to face.

The choice of such devices is very large. They differ not only in appearance and power, as well as cost. Diagram of the a simple stun gun does not require high knowledge in the field of electronics, necessary details also available for purchase. The manufacture of such a means for self-defense cannot be called very simple, moreover, the device must meet a number of requirements. Wiring diagram stun gun must be thought out so that the device is:

  • compact, inconspicuous, not causing inconvenience when moving;
  • powerful, able to neutralize the attacker and give you a few seconds to respond;
  • with the possibility of recharging, since no one needs a disposable tool.

If you decide to make a stun gun yourself, remember that a device of simple design should not consume a lot of energy. A well-made device, taking into account all necessary recommendations will serve well for a long time and provide reliable protection from intruders.

What do you need for self-manufacturing stun gun:

  • Soldering iron for alloying parts.
  • Converter.
  • ferrite rod.
  • Capacitor.
  • Discharger.
  • Wire.
  • Transformer.
  • Epoxy resin.
  • Insulating tape.

Principle of operation

What is the principle of operation of a stun gun? The circuit shown in the article assumes the following: the ignition capacitor acts on the transformer, resulting in a spark that breaks through several centimeters of air. The capacitor at this moment directly hits with all its energy. The use of a conductive channel makes it possible to charge without large losses, while maintaining not only the power of the device, but also convenient dimensions. How to make a stun gun at home? Let's get to work.

The transformer is the main part of the device, one of the most difficult to manufacture. To work, you will need a B22 armor core made of 2000NM ferrite. It will need to be wound on enameled wire(0.01 mm). You need to wind until there is about 1.5 mm of space left in the core. Excellent result it will turn out if you wind it with electrical tape. The result will be 5-6 layers.

It should be noted that it is quite difficult for non-professionals to make a stun gun with their own hands. The circuit may seem quite simple, but during manufacturing there are many details that must be taken into account. This is especially true for isolation. The wound wire must be insulated with one layer of electrical tape, and then another 6 turns should be made, but already with a denser wire with a diameter of about 0.8 mm. When making the third turn, you will need to stop and twist, after that you can continue and add 3 more turns. To ensure the strength of the structure, you can use superglue. At the end of the work, the cups need to be glued or wrapped with electrical tape again. Contacts must not come into contact with environment, otherwise we run the risk of causing damage to ourselves by current instead of defense.

Further, for work you will need a tube with a diameter of 20 mm and a length of 5 cm, made of polypropylene. In a stun gun, this part will be a sectional frame. To do this, use a drill to fix the bolt, which is suitable for the diameter of the tube, and carefully groove the grooves with an emery cloth. It is important not to damage the pipe during operation and, as a result, to obtain sections measuring 2 by 2 mm. After that, with a clerical knife, you need to make an incision up to 3 mm wide along the frame without damaging the pipe.

Second phase

So, we continue to consider how to make a stun gun with your own hands. For subsequent work, you will need a wire with a diameter of 0.2 mm. It must be wound on all sections of the frame, while it should not go beyond. For more convenient work, it is advisable to solder the beginning of the wire or fix it well with glue, leave it free at the end.

A ferrite rod with a diameter of 10 mm and a length of 50 mm must be processed using an emery wheel. The result should be a round part. The ferrite rod must be wrapped with electrical tape and made on top of 20 turns. You need to use the same wire as for the first transformer, that is, 0.8 mm. Be sure to wind in the same direction, after which you need to insulate the wire in several layers.

The main part for a homemade stun gun

The prepared rod must be inserted inside the frame, from the side where the HV winding ends, and the two windings are connected together. After that, the transformer must be placed in cardboard box and pour hot paraffin. It only needs to be melted, but not heated to high temperature. It is necessary to fill in paraffin with a margin, because after hardening it will settle a little. The excess part will be easier to cut off. Now we have the main part that will allow us to make a stun gun with our own hands. The diagram clearly shows the location of the main elements.

Charging the device

The igniting conder is charged through the bridge, and the combat conder is charged through additional diodes. Thanks to this, one chain is not created. Any transistor can be used, there are no special requirements for the resistor either. The capacitor provides inrush current limitation and serves to protect the converter. If the stun gun assembly scheme provides for the installation powerful transistor, then the capacitor can be omitted.

Installed batteries size AA in the amount of 6 pieces. Transistors are mounted on a radiator. It is desirable that it has insulating gaskets. We install all the prepared parts. Most importantly, you need to fix the HV-pins, the distance between which should be more than 15 mm. Otherwise, the stun gun has every chance of quickly burning out.

Charge frequency

Use Charger for a stun gun or not, depends on the desire of the owner. Batteries are the best for power. The stun gun does not require a specific setting, it should immediately work. If these batteries are used, the discharge frequency should be close to 35 Hertz. If this figure is lower, the transformer may be incorrectly or poorly wound, or other transistors should be selected. Empirically, you need to select the frequency of discharges. This is done through divorce. You need to test the discharge frequency for 5 seconds. The distance should not be the maximum possible, otherwise at one fine moment the stun gun may burn out. Note that air breakdown is affected by pressure, humidity and other external conditions.

Frame

What do you need for a homemade stun gun? Thick cardboard is suitable as the body of the device, on which you can immediately draw the location of all the parts, and then proceed with their installation and fastening. It is best to bend the material with pliers. Glue is applied to outside. It is important to ensure the tightness of the seam. It is better to place the parts inside the case first, and then start fixing them one by one.

Determine a place to charge the battery and the start button. It is desirable to treat the stun gun with heat shrink, this will help to drown some elements a little inside and provide a very good protection from external environment. After using heat shrink, you need to check the operation of the stun gun again. Aluminum rivets should be used as protective electrodes.

The final stage of production

After checking the operation of the stun gun and the tightness of the entire system, you can proceed to pour the device with epoxy resin. After that, you need to wait 6-7 hours. At this stage, you can cut off the extra parts, give comfortable shape until the epoxy has hardened. You can process the device with sandpaper and then varnish the finished case. The instruction manual for the stun gun does not require special explanation. This device is used for self-defense purposes, does not cause much harm to health and does not need a license.

Power of the stun gun

If the spark between the contacts of the device is small and raises doubts about the effectiveness, then you can check it. stun gun? For this purpose, it is sufficient to use a conventional mains fuse, which must be placed between the contacts, without creating a direct interaction between them. If the fuse blows, it will indicate that the output current is already over 250 mA. As a result competent work It turns out a compact and reliable means of protection with the necessary power.

Shooting stun gun

Let's take a closer look at what such a device looks like. more difficult to implement. For this reason, many prefer the conventional model of the device. This device works as follows: a special unit is installed in it, which is directly connected to the source of electricity high voltage wires; at the moment when the block hits the target, voltage is applied to the electrodes, and an electric shock occurs. The design itself is difficult to manufacture. To work, you will need a firing system and special wires. The disadvantages of such a stun gun should also include the fact that the device must be recharged after use. If there are several attackers, some difficulties may arise, and the stun gun will not provide adequate protection.

Safety when using a stun gun

It is important to remember that the device should only be used for its intended purpose and in case of danger. A stun gun is not fatal. But if a person suffers from heart disease, he can die. An electric shock to the chest area is dangerous even for a healthy person. It is safe and effective to use the device in the area of ​​the abdominal muscles, where they are responsible for the coordination of movement. Such an application will disable the intruder for some time.

Improper use of the stun gun can harm the wearer. For example, in wet weather, you can get yourself The stun gun is forbidden to use in water, near open fire and also near explosive ordnance. The thickness of the attacker's clothes does not affect the quality of the device. It is important to observe the time of exposure to a stun gun on a person. For disorientation and calling pain 1-2 seconds is enough to use the device. Prolonged use is unacceptable, as it can lead to fatal electric shock. The effect of using the device lasts an average of 20 minutes. At the same time, contact with the following areas should be avoided:

  • Chest area. The heart can fail, and the user is charged with exceeding the necessary self-defense, resulting in death.
  • Solar plexus. The person may suffocate.
  • Head. Possible cerebral hemorrhage.

There are a lot of ways to create a stun gun at home, and we have considered only one of them. In each case, one must take into account certain features and subtleties, so as not to spoil the details and not redo the work several times. The material for the manufacture of the stun gun and the result of the efforts depend on the skill and experience of the specialist. You can buy the necessary parts or get them from other unnecessary equipment. Additionally, the device can be equipped with a flashlight for convenience. It already depends on personal wishes.

Present on the market a large number of different models stun guns, which also differ in power from each other. For the purpose of self-defense, it is allowed to use a stun gun up to 3 W, and only after reaching the age of majority. Devices with higher power are only allowed for special services. Now you know how to make a stun gun at home. We hope that our article will become useful and help you make a high-quality self-defense tool with your own hands that will fully meet your expectations and last a long time.
