In addition to the fact that the stun gun is an effective weapon, it can be attributed to
self-defense equipment that does not require a license. "Why do I still have it
not yet?” you ask yourself. Probably because many people think
the use of a stun gun as a female means of self-defense, and it’s worth it
a good powerful stun gun is not cheap. But in vain! After all, instead of
buy a stun gun, you can easily make it yourself in
at home according to the schemes below.
How to make a stun gun with your own hands.
As a case for our most powerful homemade
stun gun perfect plastic shell from the usual
soldering iron. It is necessary to install plastic separating
walls between the main components of the stun gun: transformer,
multiplier, as well as between the electrodes, in order to avoid a short
short circuits and unwanted sparks in the manner shown in
the following scheme:
As can be seen from the figure, the brass antennae are the striking elements
future stun gun, the distance between them is less than between
electrodes to increase the effect of the action. However, no
a do-it-yourself stun gun will not be able to protect you from danger if you
do not stock up on patience for the manufacture of a transformer, ferrite
rod from a conventional radio receiver (diameter 8mm) or U-shaped
ferrite cast from TVS, on which many turns are wound
high voltage winding. In addition to applying insulation every thousand turns,
to separate them from each other for the greater safety of you and the product, we
we recommend using fluoroplast.
If you are not strong in winding a high-voltage winding on a transformer
or just rummage badly in electrical engineering, we will explain the option with an example
manufacturing transformer for our most powerful homemade
stun gun.
Materials needed: 0.2 mm wire, ferrite rod
type 2000NM (is a horizontal scanning transformer in
domestic televisions). It is important that its dimensions are of the order of 10 by 50
mm, if not, then you will have to manually bring the ferrite into the desired shape,
or use instead of a solid rod a lot of glued between
a ferrite ring. Also for the manufacture of a working transformer
for a stun gun, you will need a polypropylene water tube
with a diameter of 2 cm (can be bought at a plumbing store). Choosing a piece
tubes 50 mm long, we make grooves along its perimeter, in depth and
about 2 mm wide. The finished structure looks like
the following scheme:
Now about winding. Before starting, do not forget to leave a small
a piece of the initial wire sticking out so as not to forget where you started
wind. After wrapping all sections of the tube, also wrap the ferrite rod, and
exactly 20 turns of wire with a diameter of 0.8, stretching them along their entire length
ferrite.
Now wrap the product insulating so that it is effortless, but
quite tightly entered the tube of polypropylene. Attention! winding
wires to the ferrite core must be carried out synchronously with
polypropylene part, that is, observing the general direction of winding, for
slow-witted - wind in both cases either clockwise or counterclockwise.
After all the ordeals, you can take revenge on the transformer by flooding it with paraffin
(previously placed in a cardboard container and making sure that
the paraffin was not quite hot).
A do-it-yourself stun gun will work due to
DC voltage converter (diagram in the figure below), output
device is connected to a multiplier, respectively, on capacitors 220 pF per
ten kilovolts and on KTs-106 diodes, and you can power it at least from
conventional batteries, the main thing is that they give at least 9-10 V.
Explanations for the do-it-yourself stun gun scheme: I - 2 by 14, with
diameter 0.5 - 0.8, II - 2 by 6 with a diameter of 0.5 - 0.8, III - 5 by 8
thousand, with a diameter of 0.15 - 0.25.

This article will focus on the electric shock device for civilian self-defense. The author of this homemade AKA KASYAN.
Well, now, without wasting time, let's get to work. The scheme of the device is now in front of you:
It is important to note that the discharges cannot cause injury. They cause only pain shock, disorientation and muscle spasms that do not last long. Such a shocker is not capable of harming health. It is this circuitry of the electroshock device that is used all over the world for the construction of both civilian and police electroshock devices. The power of this particular option lies in the range from 7 to 10 watts. The shocker has a two-position switch. The first mode is the removal from the fuse. In this case, the red indicator LED lights up. It is worth pressing the button and the shocker will begin to crack.
Power supply- lithium ion.
The author of course tried to increase the protection current of this thing. To do this, he developed his board, raising the protection current to 6A, but this was not enough. Therefore, a battery without any protection and balancing boards is bad, so the author has already ordered a board with the required current. In the meantime, we will have a protection relay that will not work if the battery is discharged below 6V.
Very often, homemade shockers use a trigger system based on a regular button, but the author always used a relay. The fact is that the circuit consumes colossal currents from the power source, and finding compact buttons with a current of more than 10A is very problematic. Therefore, a low-power button is used, pressing which supplies power to the relay coil.
But if possible, put a relay with a coil voltage of 6V. The relay contacts are designed for a current of 20A.
Switch.
This to some extent helps the keys to close by discharging the shutter. Zener diodes are used to protect the gates from overvoltage. They need to be taken with a stabilization voltage from 6.2V to 12V, preferably single-watt.
Take gate limiting resistors with a resistance of 330 ohms to 1 kOhm. It is not necessary to put the keys on the radiator, as the shocker is designed for short-term operation. Before assembling, make sure that all components are in good condition. And most importantly - check the transistors for authenticity, otherwise they may fly out at the first start.
The inductor is wound on a compact iron powder core. Wire 0.85 mm. The number of turns can vary from 12 to 20. The dimensions of the ring are not critical, they can be found in the output parts of switching power supplies, they are after the rectifiers.
Pulse transformer.
Diodes must be designed for a reverse voltage of 6,000 to 10,000 V, a current of at least 10 mA, and must be able to operate at frequencies of 20 or more kilohertz.
The storage film capacitor is designed for a voltage of 1600-2000V, a capacitance from 0.15 to 0.47 microfarads (the larger the capacitance, the less often the discharges, but more joules in one discharge).
spark gap.
high voltage coil.
Ensuring human safety plays an important role, it is for this reason that many choose various means of 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. A 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.
Modern factory stun guns come in various types. Outwardly, they can be of 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 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. This device may only be used by persons of legal age. To purchase a stun gun in a specialized store or to make it yourself - everyone decides individually. Buying a ready-made device is quite expensive, but simple. There is an 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, but also in cost. The circuit of the simplest stun gun does not require high knowledge in the field of electronics, the necessary parts are 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. The electrical circuit of the stun gun must be thought out so that the device is:
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 the necessary recommendations, will properly serve for a long time and provide reliable protection against intruders.
What you need to make your own stun gun:
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 allows the charge to be carried out 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. An enameled wire (0.01 mm) will need to be wound on it. You need to wind until there is about 1.5 mm of space left in the core. An excellent result will be obtained 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 should not be in contact with the environment, otherwise we risk inflicting electric shock on ourselves 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.
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 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 a cardboard box and filled with hot paraffin. It only needs to be melted, but not heated to a 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.
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 of a 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.
Whether to use a 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.
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 the 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 very good protection from the 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.
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 a convenient shape, until the epoxy is very hard. 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.
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 of competent work, a compact and reliable means of protection with the necessary power is obtained.
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 by 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.
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 the Taser yourself. It is forbidden to use it in water, near an open fire, and also near explosive objects. 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. To lose orientation and cause pain, it is enough to use the device for 1-2 seconds. 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:
There are a lot of ways to create a stun gun at home, and we have considered only one of them. In each case, certain features and subtleties must be taken into account 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.
There are a large number of different models of stun guns on the market, 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 be 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.
Good day everyone!
Not so long ago, wandering through the expanses of the Internet, I came across a stun gun circuit and decided to collect what came of it, see for yourself.
Attention!!!
The main effect of the stun gun is deafening and painful. Electric current causes severe pain and introduces a person into a state of disorientation. An electrical discharge at the point of contact with the body stimulates ultra-fast muscle contraction, which leads to a short-term loss of performance. In addition, the activity of nerve endings is blocked and the brain cannot control that part of the body that was affected by electric current. Paralysis develops, which can last up to 30 minutes
Scheme:
To make a stun gun, we need:
Transistors: IRFZ48N or IRFZ44.IRF3205
Resistors: 680 ohm or 1 k ohm
Capacitors: 2n2 x 6.3 kv
Discharger
Diodes: KTS123 OR 106 (KTS123 A is better)
Transformer: From a computer power supply (I used a DF-90 PC choke)
The winding wire was taken from an old razor
Batteries format 16850-3pcs
Relay for 12 in 10a
Breadboard, wires, tin, rosin, soldering iron, well, straight arms.
For many years I have been making similar devices and each time the technology of circuitry is somewhat different. In search of a convenient and very powerful stun gun, I created a whole notebook with the development of stun guns, it is these archives that are offered to your attention. The circuit of this shocker on one transistor is very simple - a converter on a KT819 and a push-pull voltage multiplier. Now think: only two capacitors are not able to stun - but you are deeply mistaken, the power of the shocker when powered by 12 volts 2 amperes reaches 30 watts, and is able to half light an incandescent lamp with a voltage of 220 volts 60 watts.
In the photographs, the shocker is powered by a mobile phone battery with a capacity of 650 mA / h, the arc with this power supply is 1 centimeter, but when powered by 12 volts, the arc reaches 4-5 centimeters. For such parameters, you need to find capacitors with a capacity of 10 kilovolts 22000 picofarads, the code marking is attached to the article. In fact, such imported capacitors can be easily found on the radio market. The diodes in the voltage multiplier are high-voltage - domestic kts106 is the best option.
The converter is assembled on the basis of a simple blocking generator on a single transistor, a transistor - kt819 / kt805 and its imported analogues, or any other similar parameters. 100 ohm resistor with 1 watt power. The transformer is taken from a computer power supply. The primary winding contains 10 turns with a tap from the middle, it is wound with 4 strands of wire with a diameter of 0.5 mm each. Then we isolate the primary winding with several layers of transparent tape and wind the secondary winding, it contains 2000 turns of 0.08 mm wire, we isolate the winding every 80 turns. It is desirable to fill the finished transformer with epoxy resin to avoid breakdowns. And now the main secret of this shocker is a spark gap!
It's not a secret for you that the main disadvantage of shockers on a voltage multiplier is that when in contact with human skin, the pulses close through the resistance of the skin and the capacitors do not have time to charge, the spark gap serves as a spare gap, that is, the charge flows constantly through it, this voltage enough to paralyze after 1 second of using an electroshock device. The case is made of plastic, you can use the case from a Chinese LED flashlight. The shocker must be equipped with a non-latching button and a switch. It is convenient to use two batteries from a mobile phone as a power source for this stun gun on one transistor. And in the future we will consider more powerful stun guns with an anti-pull system and other interesting devices. Stay tuned, author - Artur Kasyan (AKA).
