The question of self-defense is always somehow particularly acute. Nobody wants to think that this can happen to him, but at the same time, no, no, let him think about the means that can protect him from intruders. Girls often carry gas canisters in their purses, men prefer something more serious.
However, there is a flip side to the coin - no matter how self-defense it may be, it may not always be useful and effective, and sometimes it can even turn against the one who tried to use it.
However, this is only a reason for caution, not a reason to give up self-defense. Such funds can be treated differently, but, as statistics show, their presence reduces the likelihood of occurrence of cases when they may be needed.
What means of self-defense are there? Gas cartridges, traumatic and gas pistols and stun guns . As already mentioned, cans are good, but they are more suitable for women, moreover, they do not always turn out to be effective. Any specialist will confirm that using them carefully - gas does not distinguish between friends and foes. Traumatic weapons are too dangerous and not easy to acquire. That is why stun guns coming to the fore.
And sometimes "kulibin" and jack of all trades collect a stun gun with their own hands - a combination of hobby and self-defense.
Is assembly difficult?
The most pressing question is whether it is possible to assemble a stun gun with your own hands, is it difficult to do this, what is needed for this?
You can assemble it, and this is no more complicated than any other similar event when you have to deal with electronics. A knowledgeable person will figure it out and make a portable stun gun with his own hands. For those who decide to try, you should always remember about safety measures, so as not to replenish the sad statistics.
What is needed for this?
For assembly you will need the following parts:
- Some kind of plastic case, box or something like that.
- Transformer.
- Multiplier.
- Electrodes
- Battery.
In fact, these are the main elements of the future device. In the case, partitions should be installed between the individual elements in order to avoid short circuits, and they should also be attached firmly and reliably, since it may be necessary to use a homemade stun gun in extreme conditions.
How to assemble?
0.2 mm wires and 2000 NM ferrite rods can be taken from old TVs. Instead, glued rings can be used; in any case, the shape of the shaft should be appropriate for the body and size.
To create a transformer, you will need a regular water pipe with a diameter of 2 cm and a length of 50 mm. It makes grooves for winding wire. You should also wrap the ferrite core with a wire with a diameter of 0.8 mm, making about 20 coils.
The main rule: you need to do winding on the rod and the tube in one direction - counterclockwise or clockwise.
After this, it is necessary to wind the rod with electrical tape and insert it into the polypropylene tube. The process is quite painstaking. The finished transformer can be filled with paraffin.
So, we have a transformer that can be installed in the housing. The stun gun device also includes a DC / DC converter, which must be added to the general electronic circuit according to the rules. At the output, a multiplier connected to capacitors with a capacity of at least 220 pF is connected to this device.
You can use KTs-106 diodes or similar. Thus, a do-it-yourself stun gun is done quite quickly in the presence of all the details: a transformer, rods, a multiplier with capacitors. Conventional 9-10 V batteries are sufficient for power supply. All this is installed in a plastic case for safety, equipped with a power lever. It is worth thinking about fuses to avoid accidental blows.
