How to make a stun gun from a capacitor. A simple stun gun with your own hands. Parts needed to assemble a stun gun
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.
I took the diodes from the UN9 / 27-1.3 multiplier and the winding wire from an old razor
The diodes in the multiplier are as follows:
I wound the transformer like this:
4+4 turns with 0.6 wire folded 3 times Primary winding
900 turns with wire 0.5-0.2 mm Secondary, rewound with tape every 100-110 turns
Power supply for the stun gun is necessary switch via relay and choke
I used 3 16850 batteries for power.
But the stun gun works well from 2-woo
For charging, I use a board on TP4056

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.

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 a rather stylish design thanks to the 3D carbon 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. Despite the increased output power, the shocker has a 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.
Specifications:
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 immediately with 5 strands of copper wire, each of the strands 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 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.

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 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.

How to make a stun gun
Hello dear visitors of our educational portal. This training video lesson from the master of homemade Roman Ursu will talk about the wonderful idea "How to make a stun gun with your own hands at home."
From this video tutorial, you can make a mini stun gun yourself at home. By the name of the mini, it may seem to many that since it is small, it means it is weak, but not this time. Roman will make a powerful stun gun with his own hands and we will be able to boast even than store-made, factory-made ones. For example, we can take a store stun gun such as "Bumblebee" or as everyone calls it "Wasp 618" its output power is about 300 thousand volts. And the home-made one, which we will make on our own, will have an output power of about 800 thousand volts. It is a very powerful and loud stun gun, with the help of which it will be possible to protect not only from ill-wishers, but also to scare dogs.
How to make a stun gun at home
So, for the manufacture of such a shocker, we need two converters. One of the converters converts from 3.6 volts to 400 thousand volts, so two converters will give us 800 thousand volts at the output. You can learn more about how where to buy them and which ones are the best to take from the second video lesson. To make a mini stun gun, we will also need two mini adapters in the form of sockets, a tact button, and a connector for 18650 batteries. And of course, the 18650 batteries themselves for 6000 milliamps, 3.7 volts.
First of all, using hot glue, we must glue together two converters, as well as two battery connectors. Next, we connect the minus from the connector with the minus from the converter and do the same with the second ones. As soon as we connected them together, we take glue and glue them together. Then we solder the plus from one connector with the converter to the clock button and also repeat with the second ones.
Now we take one of the adapters, disassemble and connect, one wire from the converter to one plug, and the second wire to the second plug. We disassemble the adapter completely, connect the wires, glue it to the converter, and assemble it. We do the same with the second adapter.
Our stun gun is ready, we can start testing. First, insert the batteries and test. The sound of the stun gun is very loud, but the sound transmitted through the camera is quiet. On this we will say goodbye, do not forget to recommend this video to your friends and acquaintances. Subscribe to our social groups and follow the news.
Do you or do you know?
In the West, stun guns have been used since the beginning of the 20th century. Tasers are loved by law enforcement officers, as it helps to detain a suspect without injuring him. Later, enterprising manufacturers began to produce shockers for "civilians" as well.
What you need to make a stun gun
In this video you will learn what you need to make a stun gun at home. Roman Ursu specially recorded this video where he will tell in detail about the purchased products for the stun gun. We need Pro 60W 220V soldering iron, 400000V module, 18650 connector, 2 pieces 18650 3.7V 6000mAh battery.
