Detailed diagram of a stun gun with your own hands. How to make a shocker at home

Powerful do-it-yourself electric shock at 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 3D carbon fiber coating (in the store, a meter of such carbon fiber 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.

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.

Ready multiplier is poured epoxy resin right in the ESH building.

The exit bayonets are made of solid stainless material, the distance between them is a little more than 25mm. Don't spread your bayonets long distance, although the breakdown of air 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 famous scheme Pavel Bohun (EVIL SHOCKER) in front of this device is just a toy.

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

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 powerful white LED that works through a resistor from general nutrition. 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 an ordinary bag is well suited. 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 insulated with 4 layers of electrical tape. After the winding is completed, the halves of the ferrite are combined and tightly wrapped with tape or electrical tape. The stages of manufacturing transformers in the manufacture of a homemade stun gun are the most complex and time-consuming.

To obtain a quality product, you will need to manufacture a 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 nail or screw.

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. For this, paraffin is melted in an iron dish, but it is not heated 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 any air bubbles that may have formed during the first pour. If it is possible to build a 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.

It is quite difficult to defend yourself in a closed space from an unexpectedly attacked person. 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.

That's why 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 of 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;
• a ferrite transformer pulled out of a switching power supply of an electronic device;
• fuse;
• battery for power supply;
• diodes, capacitor and resistor for 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.

1. 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.
2. On top - five more layers of electrical tape and six layers of adhesive tape.
3. We cut the plastic bag into strips ten centimeters long and a width corresponding to the length of the coil.
4. Next comes the secondary winding with a thicker wire (from 350 to 400 turns) in the same direction as the primary winding.
5. We isolate each row of wire (from 40 to 50 turns) with polyethylene tapes and five rows of adhesive tape.
6. 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.

1. For it, we take the old fuse, remove the tin on its contacts with a hot soldering iron, and pull out the inner wire.
2. We screw the screws on both sides (they should not contact).
3. 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 case, you can find something suitable by gutting a 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,?

1. 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.
2. Four high-voltage coils and converters pulled out of electric lighters for gas stoves should also be placed there.
3. Spark gaps and a separate switch are added to the circuit.
4. Each transformer has its own two contacts.
5. 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);
• a handle with a button and a metal clip, having a sufficiently large diameter, containing a piezoelectric element;
• hacksaw for metal;
• glue gun.

1. We disassemble one of the lighters and take out the piezoelectric element.
2. 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.
3. 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.
4. With a hacksaw we make an incision for the wire.
5. We put the handle button in place, glue the piezoelectric wire insulation with a thermal gun and glue it to the second part of the plastic inner sleeve.
6. 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.
7. We insert the lower part of the sleeve and assemble the handle.
8. 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.

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

We will show you how to make a mini stun gun with a power of 800,000 volts at home with your own hands. Let the word mini not bother you, many will think that if it is small, it means weak. But it's not. Our shocker will be more powerful than most store analogs. For example, let's take the popular Bumblebee stun gun, the output power of which is only 300,000 volts, while our own, made by ourselves, will have a power of about 800,000 volts. The sound of his work will be very loud and intimidating, so you can protect yourself not only from hooligans, but also scare stray dogs who are very afraid of this sound. To make a shocker, we need two such converters:

One converter converts 3.6 volts to 400,000 volts, thus two converters will provide us with 800,000 volts of power. We also need two such adapters:

One tact switch, 18650 battery connectors and these 3.6 volt 18650 batteries:

First of all, using hot glue, we glue together two converters and two battery connectors. The next step is to connect the minus from the connector to the minus from the converter, we do the same with the second. Then we glue the connectors and modules together:

After that, solder plus from one connector and plus from one module to one side of the contact button, respectively, plus from the other connector and module to the other side:

Now we disassemble one of our adapters and connect one wire from the first module to one plug and the second wire from the second module to the second plug, do the same with the second adapter. We fasten our design with hot glue, our stun gun is ready, you can test it. Many will ask where to get the parts and what is the cost of manufacturing this stun gun, at the end there will be a video with a detailed explanation of where you can purchase the components, the total cost of which is about $ 10.

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 to the primary winding of the transformer T2, inducing a high voltage pulse in its secondary winding. Since the discharge is oscillatory in nature, the voltage polarity on the C2-C6 battery is reversed, 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 inside diameter 8 mm, external 10 mm, length 20 mm, cheek diameter 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.
