The simplest alarm system is “on the knee.” Signal mine DIY signal banner with sound signal

In our online store you can buy a signal mine SM-320 at affordable price. We offer you high-quality products, which are supplied with instructions and all the necessary accompanying documents. They indicate the manufacturer of the product, describe how to properly install a signal mine, and provide information about safety rules that must be followed.

The signal mine is used to achieve the following goals:

• transmission of data to the military that enemy forces have appeared in the areas where the projectile was installed;
• imitation of the explosion of a live projectile during an exercise.

Signal mine: configuration features

Here is a complete product consisting of the following components:

• the projectile itself, which is sold partially loaded;
• an unloaded fuse with a pin (P-shaped rod);
• trip wire with carabiner;
• wooden peg for attaching a signal mine.

The projectile itself is made in the form of a steel body (case), special blocks are placed in it, responsible for reproducing signals (sound + light). They are enclosed in a sleeve made of paper. The system responsible for sound reproduction has two components - ignition and sound. The light block includes from 12 to 15 stars of lights different colors- white, green or red, between which are inserted cardboard spacers and expelling charges.

The signal mine can be fully armed. To do this, it is necessary to screw the fuse mechanism onto the sleeve, and if the product is stored, use a plastic cap.

How does a flare mine work?

The SM-320 signal mine functions as follows:

• if the tension wire is pulled, the pin is pulled out;
• the striker pricks the ignition cap of the signal mine;
• the unit responsible for sound is triggered (when the composition is on fire, a whistle occurs);
• The light block is triggered, the burning stars fly out of the cartridge one by one (full ignition takes 10-12 seconds).

How to install a signal mine correctly?

If you plan to use the presented products in practice, you must understand how to properly install a signal mine. All operations are carried out manually, installation is carried out in the ground, and if this is not possible, on the surface of the earth. You can also attach the projectile to any object (tree, wall, etc.). Near the place where the SM-320 signal mine is installed, a peg is driven in and a projectile is tied to it.

When working with a mine, you need to be extremely careful, since the shell fuse is characterized by high level sensitivity.

Ultrasonic tripwire mine

The long-awaited new product from FORPOST. A trip mine with an ultrasonic motion sensor is a device that can diversify laser tag and add new scenarios to the game. The way we implemented the tripwire mine, in terms of its functional characteristics, makes it the most attractive among existing analogues.

home distinctive feature tripwire mines from the FORPOST company - this is their operating principle, thanks to an ultrasonic motion sensor located on the front panel of the mine. Unlike an infrared motion sensor, which loses some of its capabilities in bright sunlight or artificial light, an ultrasonic sensor works stably regardless of the light level. Also, the ultrasonic sensor has a more concentrated signal range, due to which the “target acquisition angle” does not exceed 15 degrees!
The mine is triggered when crossing the space in front of it within 4 meters. This makes it as close as possible to the real analogue.

Characteristics
Dimensions (height, width, thickness) 14cm x 8.4cm x 9.5cm
Damage radius 10 m
Target acquisition distance 4 m
Battery type Li-ion 2.2 Ah
Battery life 36 hours
Instructions for use of trip mines
The device is equipped with IR emitters on each side (6 pieces in total). When a mine is triggered, the damage radius is 10 meters.

The front panel of the mine has a built-in damage sensor, which allows it to be deactivated. To do this, you need to fire 15 well-aimed shots at the damage sensor, after which the mine will switch from combat to standby mode.

The mine is activated by a button on the top of the body. Activates within 5 seconds. from the moment of switching on. The activation process is accompanied by a sound signal from the speaker on the side panel and a light indication, at this moment the diode on the front panel changes color from green to red. When the diode lights up red and goes out, and the sound signal stops, the mine is activated.

After a player crosses the space in front of the mine sensor within 4 meters, the mine is triggered and hits all players within a 10 meter radius. In case of explosion, mine for 3 seconds. produces 10 damaging signals. The explosion is accompanied by a characteristic sound from the speaker.

After the explosion, the diode on the mine lights up green and goes into flashing mode. In order for the player to activate the mine again, he must wait 5 minutes after the explosion, or the instructor/referee can do this immediately. To do this, use the button " A new game» update the mine by pointing the remote control at its front panel, and then restart it with the power button. When the mine is ready to be activated and goes from standby mode to standby mode, the diode will start blinking blue rather than green.

The tripwire mine is suitable for any scenario. Can be used both indoors and outdoors. It is recommended to install: at the entrance/exit of the building, in doorways, at turns, behind shelters, bushes, trees.

It's no secret that many project participants are not strong in radio electronics. To my last publication on the topic of simple alarms, many responded in the style of “The topic is good, but I can’t put it together.” This prompted me to publish another “our” homemade product that anyone can assemble in 5 minutes, regardless of the crookedness of their hands.
This is also a universal answer to those who wrote that my publications contain little practice and personal experience.

It requires a minimum of parts, and the only radio components are an LED (which, if desired, can be replaced with a squeaker from any children's toy). Price finished product- about 15 rubles and this includes the battery

The application is the widest, and the design can be easily modified (with the help of a simple children's toy) and can be used to provide not only a light signal, but also a sound signal. Has two trains, which allows you to overlap with stretch marks large area. We used such stretchers both for training (obstacle course) and for camp when hiking.

ATTENTION: This is completely the development of our team, and you will not find anything like this anywhere, so to speak, exclusive to the site. If you want to drag it to your blog or to some forum, please agree with me.

Let's get started.
We will need:

• 3 volt coin cell battery
• A piece of thin wire (5 cm)
• LED (or 3 volt toy squeaker)
• Half blade
• A piece of plastic (for example, from a discount card)
• Terminal block for 2 contacts.
• Scotch.

Almost all of this, except for the tape and wiring, is shown in the photo below.


We take out the metal pads from the terminal blocks and screw them to a strip cut out of plastic at a distance slightly less than the length of the blade.


On the back side of the platform we fasten a piece of uninsulated wire to the bolts.


Now we attach (observing polarity) the battery, blade and LED. With the correct polarity, the circuit should work immediately (the diode will light up).




We move the LED diagonally and fix the structure with tape. We insert pieces of paper at both ends of the blade for insulation.


We wrap the peg for ease of installation.


Now, instead of pieces of paper, we make pieces of thin plastic (although you can cut a playing card, even take it from the packaging), to which we tie a fishing line, which will serve as a stretcher.

Such a device is attached to the barrel with tape or rope. If you install it on the ground, then we simply stick a peg. There is no need to drive it in hard, since there is practically no load. By the way, the bright beam of the LED is clearly visible to sentries at a distance of more than 50 meters, which is quite enough to cover the approaches to the base.

Thank you all for your attention and have a good weekend.

Great experience Patriotic War is replete with examples of successful actions of small sabotage groups and partisan detachments against large military formations. For example, in 1942 in Leningrad region There was a raid reconnaissance and sabotage group of only 22 people, consisting of several experienced demolition miners and student athletes from the Lezgaft Institute. The group inflicted such damage on the Germans (23 trains that were blown up) that its destruction was entrusted to two SS battalions. The SS men were supported by tanks, aircraft and artillery.
For several months the Germans tried in vain to encircle and destroy the reconnaissance group, which was nicknamed “Black Death”. The scouts themselves successfully attacked their pursuers, destroying 18 tanks, 2 aircraft, 143 trucks and 84 cars. A small sabotage group practically destroyed one of the two SS battalions pursuing it.
The ability of demolition miners to make exploding surprises from improvised means helped the scouts to resist the enemy prepared for counterinsurgency operations. By setting up ambushes and evading raids, the partisans lured the Germans into deadly traps. They used seemingly completely harmless things, successfully mining roads and paths, equipment and weapons, seemingly using absolutely inappropriate means for this.
In Chechnya not only military intelligence officers, but units of the Ministry of Internal Affairs and the FSB also often had to act in small groups against superior enemy forces. The “special forces surprises” described below will help scouts in such a situation break away from their pursuers. These booby traps are easy to manufacture and use standard ammunition and equipment.

Fig 1. Anti-personnel mine from hand grenade

The heroes of many action films blew up the enemy by attaching a trip wire to the safety pin of a fragmentation grenade. This method caused a fair smile from those who have ever thrown live grenade and knows how tightly the pin sits, with what effort it is pulled out. The proposed product can be successfully installed in the enemy's path as a fragmentation mine activated by a tripwire.

Required materials:
manual fragmentation grenade with UZRGM fuse;
cylindrical container with a diameter of slightly larger size grenades (glass, mug, ration can, pot, etc.)
strong thin wire or fishing line.
The dimensions of the container must be such that when the safety pin is pulled from a grenade located in this container, the walls of the container do not allow the grenade fuse to operate.

Manufacturing process:
securely tie the container to a tree, branch or other similar stopper;
tie the end of the tripwire to the grenade so that it does not interfere with the fuse firing;
insert the grenade into the container;
stretch the tripwire in the enemy's path at a small height with a slight slack and tie the second end of the tripwire to a peg (If you need to mine an object, tie the tripwire to it);
disguise the device;
Carefully pull the safety pin from the grenade fuse.
This device has drawbacks: when triggered, a loud bang is heard and only after 3.8-4.2 seconds an explosion occurs. This can be avoided if the UZRGM's powder moderator and detonator are unscrewed and the MD2 detonator is screwed in instead.

Fig 2. Delayed action mine

Required materials:
hand grenade with UZRGM fuse
fuse.

Manufacturing procedure:
Tie one end of the fire cord in a knot around the grenade body so that it grabs the safety lever of the UZRGM fuse and presses it tightly to the grenade body, preventing it from triggering after pulling the pin;
the distance from the knot tied on the grenade to the end of the fire cord will determine the deceleration time.

Application:
take the grenade in your hand and, holding the safety lever with your fingers, pull out the ring;
slowly open your fingers and make sure that the fire cord securely holds the safety lever from being activated;
light the fire fuse

Such a “slow” grenade can be thrown using a regular rope much further than the usual grenade throw range (25-30 m).

Required materials:
hand grenade;
fuse;
twine, cord, etc.

Manufacturing procedure:
cut a piece of rope about 1.5 m long and tie one end of it to the grenade so that it does not interfere with the fuse (that is, without pressing the safety lever);
at the other end of the rope, tie a large knot that will act as a handle;
tie a fire cord around the grenade (see above);
Carefully, holding the safety lever with your hand, pull the safety pin out of the fuse.

Application:
ignite the fire cord;
spin the grenade over your head;
after three to four turns, when the grenade is aimed at the target, release the rope. With known experience, the throwing range can reach from 50 to 100 m.
In addition, grenades with a delay can be set so that they explode in the rear of the pursuing enemy and distract him, disorient him and instill uncertainty.

Figure 3. To increase the deceleration time and reduce the consumption of the fire cord, you can make a delayed igniter from a cigarette.

Required materials:
cigarette;
match;
thin wire or thread;
fuse.

Manufacturing procedure:
make an oblique cut of the fire cord;
make an igniter as shown in Fig. 3 and light the cigarette. In this case, the head of the match should be located at the powder core of the fire cord.
ATTENTION. The cigarette should be in such a position that nothing interferes with its burning. Typically, a dry cigarette in windless, dry weather burns at a speed of 2.5 cm per 7-8 minutes. It is recommended to carry out a trial test to measure the burning rate before using the igniter in combat.

Photo 4. In order to detain the enemy, on the path of his advance, you can set up a trap - a crossbow from an automatic weapon on a tripwire.

This type of trap not only hits the enemy, but also creates the illusion that the pursued have stopped and gone on the defensive. The machine gun should be pointed in the direction of the likely appearance of the enemy and firmly tied to the trees in two places. It is advisable to rest the butt against a solid support (so that the weapon does not swing from recoil).

Photo 5. If you want the weapon to fire with a fan-shaped dispersion, then the machine gun should be mounted on flexible trees or bushes.

When securing the weapon, make sure that nothing interferes with the movement of the bolt frame when firing. For such traps using a jammed bolt frame, you should not use PKM machine gun due to the peculiarities of its design. This type of weapon must have a jammed trigger.

Weapon preparation:
extend the tripwire into the opponent's path;
Attach a wedge to the stretcher (a cylindrical piece of wood 2-2.5 cm long with a diameter of 1-2 cm);
attach a loaded magazine to the machine gun;
send the cartridge into the chamber;
set the translator to automatic fire;
move the bolt frame back a little and, inserting a wedge into the resulting gap, jam the bolt frame forward;
press the trigger all the way and lock it in the pressed position, tying it to the pistol grip with a strong cord;
disguise the machine gun.

ATTENTION. For AKS0 74, the length of the wedge should be 2-2.5 cm. With a shorter length, the trigger breaks off the cocking, but the firing pin does not reach the primer. For other types of weapons, the wedge length is selected experimentally, and the magazine is not connected during selection.

The range of handicraft booby traps and surprises is vast and varied.
We have chosen the simplest and easiest to make. For installation, standard equipment is used and is not required special knowledge and skills. In addition, the methods described are unlikely to be used by criminals, terrorists or other criminal elements.

Many have probably encountered such a thing as local rednecks, from whom you can expect anything from thefts to attacks. And so I wanted to make a couple of stretch marks from aluminum for a 12 signal cartridge, only one question is whether this is legal in theory if you can no longer shoot shot from aluminum, but on the other hand, the manufacture of weapons can be attributed...

Mess 11-02-2008 23:27

There is an almost ready-made factory solution. It's called the hunter's signal. With your own starting device. You can put 4 pieces around the perimeter, and you can sleep peacefully. The main thing is to clearly orient it VERTICALLY, so that later someone is not taken away HORIZONTALLY, and another is not escorted to places not so distant. In general, the topic is slippery.

rain, dew is not a problem, it holds everything (these are mines) and we tie the grenades in the bottom with a check, the dampness does not take effect, it gives in the form of a pop a little louder than firecrackers and the “passenger” is in paint, the grenades were thrown into a barrel of water, it does not sink itself, it explodes on the surface if with the cargo, it sinks successfully (you won’t drown out the fish), but if the authorities are blown up, then everything here is legal and these are safety measures (we didn’t get them, though)

I have in my collection another fact of identifying a freak in the tracks of a service dog (without the participation of SM). It turned out to be the son of a neighbor from the other side of the garden. After the conversation, dad gave the money to the 6 robbed people, sold the dacha and... apparently had a serious talk with his son...

There was a similar incident several years ago in Vladivostok. Colonel Russian army planted an anti-personnel mine at his dacha after it was robbed by homeless people. When they came on the trail. Since then there is nothing left of them and of the dacha too. The owner of the dacha was forcibly sent to a “resort” for 15 years. They also added an article about the theft of explosives.
