Instructions

Take an unnecessary pocket film camera with a flash. Remove the batteries from it. Put on rubber gloves and disassemble the device.

Discharge the flash storage capacitor. To do this, take a resistance of about 1 kOhm and a power of 0.5 W, bend its leads, clamp it in small pliers with insulated handles, then, holding the resistor only with the help of pliers, close the capacitor with it for several tens of seconds. After this, finally discharge the capacitor , closing it with the blade of a screwdriver with an insulated handle for a few more tens of seconds.

Measure the voltage - it should not exceed a few volts. If necessary, discharge the capacitor again. Solder a jumper to the terminals of the capacitor.

Now discharge the capacitor in the sync contact circuit. It has a small capacity, so to discharge it, it is enough to briefly close the sync contact. At the same time, keep your hands away from the flash lamp, since when the sync contact is triggered, it receives an impulse from a special booster high voltage.

Take a hollow frame with a diameter of several. Wind several hundred turns of insulated wire about a millimeter in diameter around it. Wrap several layers of insulating tape over the winding.

Connect the coil in series with the flash storage capacitor. If the camera does not have a flash test button, connect a well-insulated button, for example, a bell, in parallel with the sync contact.

Make small recesses in the body of the device to lead out the wires from the button and coil. They are needed so that when assembling the case these wires do not get pinched, which threatens to break them. Remove the jumper from the flash storage capacitor. Assemble the device, then remove the rubber gloves.

Insert batteries into the device. Turn it on by turning the flash away from you, wait until the capacitor charges, and then insert a screwdriver blade into the coil. Hold the screwdriver by the handle so that it does not fly out, and press the button. Simultaneously with the flash, an electromagnetic pulse will occur, which will magnetize the screwdriver.

If the screwdriver is not magnetized well enough, you can repeat the operation several more times. As the screwdriver is used, it will gradually lose magnetization. There is no need to worry about this - because now you have a device with which you can always restore it. Please note that not all home craftsmen like magnetized screwdrivers. Some people find them very comfortable, others - on the contrary, very inconvenient.

Are you fed up with your neighbors' loud music or just want to make some interesting electrical equipment yourself? Then you can try to assemble a simple and compact electromagnetic pulse generator that can disable electronic devices nearby.

An EMR generator is a device capable of generating a short-term electromagnetic disturbance that radiates outward from its epicenter, thereby disrupting the operation of electronic devices. Some EMR bursts occur naturally, for example in the form of electrostatic discharge. There are also artificial EMP bursts, such as a nuclear electromagnetic pulse.

IN this material It will be shown how to assemble a rudimentary EMP generator using commonly available items: a soldering iron, solder, a disposable camera, a push-button switch, insulated thick copper cable, enamel-coated wire, and a high-current latched switch. The presented generator will not be very powerful in terms of power, so it may not be able to disable serious equipment, but it can affect simple electrical appliances, so this project should be considered as a training project for beginners in electrical engineering.

So, first, you need to take a disposable camera, for example, Kodak. Next you need to open it. Open the case and locate the large electrolytic capacitor. Do this with rubber dielectric gloves to avoid getting an electric shock when the capacitor is discharged. When fully charged, it can show up to 330 V. Check the voltage on it with a voltmeter. If there is still a charge, remove it by shorting the capacitor terminals with a screwdriver. Be careful, when shorted, a flash will appear with a characteristic pop. After discharging the capacitor, remove the circuit board it is mounted on and locate the small on/off button. Unsolder it, and in its place solder your switch button.

Solder two insulated copper cables to the two terminals of the capacitor. Connect one end of this cable to a high current switch. Leave the other end free for now.

Now you need to wind the load coil. Wrap the enamel-coated wire 7 to 15 times around a 5cm diameter round object. Once the coil is formed, wrap it with duct tape to make it safer to use, but leave two wires protruding to connect to the terminals. Use sandpaper or a sharp blade to remove the enamel coating from the ends of the wire. Connect one end to the capacitor terminal and the other to a high-current switch.

Now we can say that the simplest electromagnetic pulse generator is ready. To charge it, simply connect the battery to the corresponding pins on the capacitor circuit board. Bring some portable electronic device that you don't mind to the coil and press the switch.

Remember not to hold down the charge button while generating EMP, otherwise you may damage the circuit.

Scientific and technological progress is developing rapidly. Unfortunately, its results lead not only to the improvement of our lives, to new amazing discoveries or victories over dangerous illnesses, but also to the emergence of new, more advanced weapons.

Throughout the last century, humanity has been racking its brains to create new, even more effective means of destruction. Poisonous gases, deadly bacteria and viruses, intercontinental missiles, thermonuclear weapons. There has never been a period in human history when scientists and the military collaborated so closely and, unfortunately, effectively.

Many countries around the world are actively developing weapons based on new physical principles. The generals very carefully observe the latest achievements of science and try to use them to their service.

One of the most promising areas of defense research is work in the field of creating electromagnetic weapons. In the tabloid press it is usually called an “electromagnetic bomb”. Such research is very expensive, so only rich countries can afford it: the USA, China, Russia, Israel.

The principle of operation of an electromagnetic bomb is to create a powerful electromagnetic field, which disables all devices whose operation is related to electricity.

Is not the only way the use of electromagnetic waves in modern warfare: mobile generators of electromagnetic radiation (EMR) have been created that can disable enemy electronics at a distance of up to several tens of kilometers. Work in this area is actively carried out in the USA, Russia, and Israel.

There are even more exotic military uses of electromagnetic radiation than an electromagnetic bomb. Most modern weapons use the energy of powder gases to destroy the enemy. However, everything may change in the coming decades. Electromagnetic currents will also be used to launch the projectile.

The principle of operation of such an “electric gun” is quite simple: a projectile made of conductive material is pushed out at high speed over a fairly wide range under the influence of a field. long distance. They plan to put this scheme into practice in the near future. Americans are working most actively in this direction, successful developments weapons with this principle of operation are unknown in Russia.

How do you imagine the beginning of World War III? Blinding flashes of thermonuclear charges? The groans of people dying from anthrax? Strikes from hypersonic aircraft from space?

Things could be completely different.

There will indeed be a flash, but not very strong and not incinerating, but rather similar to a clap of thunder. The “interesting” part will begin later.

Even switched off ones will light up fluorescent lamps and TV screens, the smell of ozone will hang in the air, and wiring and electrical appliances will begin to smolder and sparkle. Gadgets and Appliances, which contain batteries, will heat up and fail.

Almost all internal combustion engines will stop working. Communications will be cut off, the media will not work, cities will be plunged into darkness.

People will not be harmed; in this regard, an electromagnetic bomb is a very humane type of weapon. However, think for yourself what life will turn into modern man, if you remove from it devices whose operating principle is based on electricity.

The society against which a weapon of this kind will be used will be thrown back several centuries.

How it works

How can you create such a powerful electromagnetic field that can have a similar effect on electronics and Electricity of the net? Is the electronic bomb a fantastic weapon or can similar ammunition be created in practice?

The electronic bomb has already been created and has already been used twice. We are talking about nuclear or thermonuclear weapons. When such a charge is detonated, one of the damaging factors is the flow of electromagnetic radiation.

In 1958, the Americans detonated a thermonuclear bomb over the Pacific Ocean, which led to a disruption in communications throughout the region; there was no communication even in Australia, and there was no light in the Hawaiian Islands.

Gamma radiation, which is produced in excess during a nuclear explosion, causes severe electron pulse, which extends over hundreds of kilometers and turns off all electronic devices. Immediately after the invention of nuclear weapons, the military began developing protection for their own equipment from such explosions.

Work related to the creation of a strong electromagnetic pulse, as well as the development of means of protection against it, is carried out in many countries (USA, Russia, Israel, China), but almost everywhere they are classified.

Is it possible to create a working device based on other less destructive operating principles than a nuclear explosion? It turns out that it is possible. Moreover, similar developments were actively carried out in the USSR (they continue in Russia). One of the first to become interested in this direction was the famous academician Sakharov.

It was he who first proposed the design of a conventional electromagnetic munition. According to his idea, a high-energy magnetic field can be obtained by compressing the magnetic field of a solenoid with a conventional explosive. Such a device could be placed in a rocket, shell or bomb and sent to an enemy target.

However, such ammunition has one drawback: its low power. The advantage of such shells and bombs is their simplicity and low cost.

Is it possible to defend yourself?

After the first tests of nuclear weapons and the identification of electromagnetic radiation as one of its main damaging factors, the USSR and the USA began to work on protection against EMP.

The USSR approached this issue very seriously. The Soviet army was preparing to fight in a nuclear war, so all military equipment was manufactured taking into account the possible impact of electromagnetic pulses on it. To say that there is no protection from it at all is a clear exaggeration.

All military electronics were equipped with special screens and reliably grounded. It included special safety devices, and developed an electronics architecture that was as resistant to EMP as possible.

Of course, if you get into the epicenter of a high-power electromagnetic bomb, the defense will be broken, but at a certain distance from the epicenter, the probability of damage will be significantly lower. Electromagnetic waves propagate in all directions (like waves on water), so their strength decreases in proportion to the square of the distance.

In addition to protection, electronic means of destruction were also developed. They planned to use EMP to shoot down cruise missiles; there is information about the successful use of this method.

Currently, mobile systems are being developed that can emit EMP high density, disrupting the operation of enemy electronics on the ground and shooting down aircraft.

Content:

An electromagnetic pulse (EMP) is a natural phenomenon caused by the sudden acceleration of particles (mainly electrons), which results in an intense burst of electromagnetic energy. Everyday examples of EMR include lightning, combustion engine ignition systems, and solar flares. Although an electromagnetic pulse can damage electronic devices, this technology can be used to purposefully and safely disable electronic devices or to ensure the security of personal and confidential data.

Steps

1 Creation of an elementary electromagnetic emitter

1. 1 Gather the necessary materials. To create a simple electromagnetic emitter, you will need a disposable camera, copper wire, rubber gloves, solder, a soldering iron and an iron rod. All these items can be purchased at your local hardware store.
   • The thicker the wire you take for the experiment, the more powerful the final emitter will be.
   • If you cannot find an iron rod, you can replace it with a rod made of non-metallic material. However, please note that such a replacement will negatively affect the power of the pulse produced.
   • When working with electrical parts that can hold a charge, or when passing electrical current through an object, we strongly recommend wearing rubber gloves to avoid possible electrical shock.
2. create an electromagnetic pulse 2 Assemble the electromagnetic coil. An electromagnetic coil is a device that consists of two separate, but at the same time interconnected parts: a conductor and a core. In this case, the core will be an iron rod, and the conductor will be copper wire.
   • Wrap the wire tightly around the core, leaving no gaps between turns. Don't wrap the entire wire, leave a small amount at the edges of the winding so you can connect your coil to the capacitor.
3. create an electromagnetic pulse 3 Solder the ends of the electromagnetic coil to the capacitor. The capacitor, as a rule, has the form of a cylinder with two contacts, and it can be found on any circuit board. In a disposable camera, such a capacitor is responsible for the flash. Before unsoldering the capacitor, be sure to remove the battery from the camera, otherwise you may receive an electric shock.
   • While you are working with the circuit board and capacitor, rubber gloves will protect you from electrical shocks.
   • Click the camera a couple of times after removing the battery to use up the accumulated charge in the capacitor. Due to the accumulated charge, you can get an electric shock at any time.
4. 4 Find a safe place to test your electromagnetic emitter. Depending on the materials involved, the effective range of your EMP will be approximately one meter in any direction. Be that as it may, any electronics caught by the EMP will be destroyed.
   • Don't forget that EMR affects any and all devices within the affected radius, from life support devices, such as pacemakers, to mobile phones. Any damage caused by this device via EMP may result in legal consequences.
   • A grounded area, such as a tree stump or plastic table, is an ideal surface for testing an electromagnetic emitter.
5. 5 Since electromagnetic fields only affect electronics, consider purchasing an inexpensive device from your local electronics store. The experiment can be considered successful if, after activation of the EMP, the electronic device stops working.
   • Many office supply stores sell fairly inexpensive electronic calculators with which you can check the effectiveness of the created emitter.
6. 6 Insert the battery back into the camera. To restore the charge, you need to pass electricity through the capacitor, which will subsequently provide your electromagnetic coil with current and create an electromagnetic pulse. Place the test object as close to the EM emitter as possible.
   • The presence of an electromagnetic field is generally impossible to determine by eye. Without a test object, you will not be able to confirm the successful creation of the EMP.
7. create an electromagnetic pulse 7 Let the capacitor charge. Allow the battery to charge the capacitor again by disconnecting it from the electromagnetic coil, then, using rubber gloves or plastic tongs, connect them again. If you work with bare hands, you risk getting an electric shock.
8. create an electromagnetic pulse 8 Turn on the capacitor. Activating the flash on the camera will release the electricity stored in the capacitor, which, when passed through the coil, will create an electromagnetic pulse.
   • The created electromagnetic field will affect any electronics, including those that are turned off. If you have chosen a calculator as the test object, then after turning on the capacitor, and if an EM pulse is successfully created, the calculator will no longer turn on.

2 Creation of a portable EM radiation device

1. 1 Gather everything you need. Building a portable EMR device will go more smoothly if you have all the necessary tools and components with you. You will need the following items:
   • AA battery
   • Matching battery compartment
   • Copper wire
   • Cardboard box
   • Disposable camera (with flash)
   • Insulating tape
   • Iron core (preferably cylindrical)
   • Rubber gloves (recommended)
   • Simple switch
   • Solder and soldering iron
   • Radio antenna
2. 2 Remove the circuit board from the camera. Inside the disposable camera there is a circuit board, which is responsible for its functionality. First, remove the batteries, and then the board itself, not forgetting to mark the position of the capacitor.
   • By working with the camera and capacitor in rubber gloves, you will thereby protect yourself from possible electric shock.
   • Capacitors are typically shaped like a cylinder with two terminals attached to a board. This is one of the most important parts of the future EMR device.
   • After you remove the battery, click the camera a couple of times to use up the accumulated charge in the capacitor. Due to the accumulated charge, you can get an electric shock at any time.
3. 3 Wrap the copper wire around the iron core. Take enough copper wire so that evenly spaced turns can completely cover the iron core. Also make sure that the coils fit tightly together, otherwise it will negatively affect the EMP power.
   • Leave a small amount of wire at the edges of the winding. They are needed to connect the rest of the device to the coil.
4. 4 Apply insulation to the radio antenna. The radio antenna will serve as a handle on which the reel and camera board will be attached. Wrap electrical tape around the base of the antenna to protect against electric shock.
5. 5 Secure the board to a thick piece of cardboard. The cardboard will serve as another layer of insulation, which will protect you from unpleasant electrical discharge. Take the board and secure it to the cardboard with electrical tape, but so that it does not cover the paths of the electrically conductive circuit.
   • Secure the board face up so that the capacitor and its conductive traces do not come into contact with the cardboard.
   • On a cardboard backing for printed circuit board There should also be enough space for the battery compartment.
6. 6 Attach the electromagnetic coil to the end of the radio antenna. Since electrical current must pass through the coil to create EMI, it is a good idea to add a second layer of insulation by placing a small piece of cardboard between the coil and the antenna. Take electrical tape and secure the spool to a piece of cardboard.
7. 7 Solder the power supply. Locate the battery connectors on the board and connect them to the corresponding contacts on the battery compartment. After this, you can secure the whole thing with electrical tape on a free section of cardboard.
8. 8 Connect the coil to the capacitor. You need to solder the edges of the copper wire to the electrodes of your capacitor. A switch should also be installed between the capacitor and the electromagnetic coil to control the flow of electricity between the two components.
   • You should remain wearing rubber gloves during this stage of assembling the EMP device. The remaining charge in the capacitor could cause you to receive an electric shock.
9. 9 Attach the cardboard backing to the antenna. Take electrical tape and firmly attach the cardboard backing along with all the parts to the radio antenna. Secure it over the base of the antenna, which you should have already wrapped with electrical tape.
10. 10 Find a suitable test object. A simple and inexpensive calculator is ideal for testing a portable EMR device. Depending on the materials and equipment used to construct your device, the EM field will either operate in close proximity to the coil or cover a distance of up to one meter around it.
    • Any electronic device that comes within the range of the EM field will be damaged. Make sure that there are no electronic devices near your chosen test site that you would not want to damage. All responsibility for damaged property will rest with you.
11. 11 Test your portable EMR device. Make sure the device switch is in the OFF position, then insert the batteries into the battery compartment on the cardboard backing. Hold the device by the insulated antenna base (like a proton accelerator from Ghostbusters), point the coil towards the test object and turn the switch to the "ON" position.
    • If you are unsure of your knowledge and skills in connecting electronic components, wear rubber gloves when handling the device as an additional precaution.
    • If the experiment is successful, the object under test, along with other electronics that are in the effective range of the EM field, will stop working.
    • Depending on the capacitor involved, the required voltage to charge it will also be different. The capacitance of the capacitor in a disposable camera is somewhere between 80-160 uF, and the voltage should be between 180-330 volts.

• The size of the copper wire and the length of the coil will determine the strength and radius of the electromagnetic pulse. To be on the safe side, before you start building a larger, more powerful emitter, start with small device to check the effectiveness of your design.

Warnings

• All responsibility for property damaged by the electromagnetic field will rest with you.
• Working with electromagnetic pulses is extremely dangerous. There is a high probability of defeat electric shock, and in more rare cases - explosion, fire or damage to electronics. Before creating a copper coil, remove all electronic devices from the room or work area. Any electronic devices within a few meters of the pulse will be damaged.

What you will need

• Copper wire (EM emitter)
• Disposable camera (EM emitter)
• Iron rod (EM emitter)
• Solder and soldering iron (EM emitter)
• AA battery (portable EMR device)
• Battery compartment (Portable EMR device)
• Copper Wire (Portable EMR Device)
• Cardboard box (portable EMR device)
• Disposable camera (with flash; portable EMR device)
• Electrical tape (portable EMR device)
• Iron core (preferably cylindrical; portable EMR device)
• Rubber gloves (recommended for both devices)
• Simple electrical switch (portable EMI device)
• Solder and soldering iron (handheld EMR device)
• Radio antenna (portable EMR device)

It is known from the civilian defense course that electromagnetic pulse appears during a nuclear explosion and causes enormous destruction. However, of course, not everyone is like that pulse so dangerous. If desired, it can be made completely low-power, just as a spark in a piezo lighter is a tiny exact copy of a huge lightning bolt.

Instructions

1. Take an obscene pocket film camera with a flash. Pull the batteries out of it. Put on rubber gloves and disassemble the unit.

2. Discharge the flash storage capacitor. To do this, take a resistor with a resistance of about 1 kOhm and a power of 0.5 W, bend its ends, clamp it in small pliers with insulated handles, then, holding the resistor only with the help of pliers, short-circuit the capacitor with it for several tens of seconds. After this, completely discharge capacitor, closing it with the blade of a screwdriver with an insulated handle for a few more tens of seconds.

3. Measure the voltage across the capacitor - it should not exceed a few volts. If necessary, discharge the capacitor a second time. Solder a jumper to the capacitor ends.

4. Now discharge the capacitor in the sync contact circuit. It has a small capacity, therefore, to discharge it, it is enough to briefly close the synchro contact. At the same time, keep your hands away from the flash lamp, because when the sync contact is triggered, it receives from a special step-up transformer pulse high voltage.

5. Take a hollow dielectric frame with a diameter of several millimeters. Wind several hundred turns of insulated wire about a millimeter in diameter around it. Wrap several layers of insulating tape over the winding.

6. Switch on the coil in stages with the flash storage capacitor. If the camera does not have a flash test button, connect a button with excellent insulation, say, a bell, in parallel with the sync contact.

7. Make small recesses in the body of the unit to accommodate the wires from the button and coil. They are necessary so that when assembling the case these wires do not become pinched, which can lead to them breaking. Remove the jumper from the flash storage capacitor. Assemble the unit, then remove the rubber gloves.

8. Insert batteries into the unit. Turn it on by turning the flash away from you, wait until the capacitor charges, and then insert a screwdriver blade into the coil. Hold the screwdriver by the handle so that it does not fly out, and press the button. Simultaneously with the flash, an electromagnetic pulse, the one that will magnetize the screwdriver.

9. If the screwdriver is not magnetized satisfactorily, you can repeat the operation several more times. As you use the screwdriver, it will gradually lose magnetization. There is no need to worry about this - now you have a device that can invariably restore it. Please note that not every home craftsman likes magnetized screwdrivers. Some consider them very comfortable, others – on the contrary, very uncomfortable.

Skeptical people at result to the question about actions in case of nuclear explosion they will say that you need to wrap yourself in a sheet, go out into the street and form lines. in order to accept death as it is. But experts have developed a number of recommendations that will help you survive a nuclear explosion.

Instructions

1. When acquiring information about a possible nuclear explosion in the area where you are, you should probably go down to an underground shelter (bomb shelter) and not leave until you receive other instructions. If there is no such probability, you are on the street and there is no chance of getting into the room, take cover behind any object that may represent security, in extreme cases, lie flat on the ground and cover your head with your hands.

2. If you are so close to the epicenter of the explosion that the flash itself is visible, remember that you need to take cover from the radioactive fallout that will appear in this case within 20 minutes, it all depends on the distance from the epicenter. It is important to remember that radioactive particles are carried by wind for hundreds of kilometers.

3. Do not leave your shelter without an official statement from authorities that it is safe to do so. Try to make your stay in the shelter as comfortable as possible, maintain proper sanitary conditions, use water and food sparingly, allow more food and drink for children, sick and elderly people. It is likely that you will provide assistance to the management of the bomb shelter; being in a confined space of a large number of people may not be pleasant, and the duration of such forced cohabitation may vary from one day to a month.

4. When returning to your home, it is important to remember and follow several rules. Before entering the house, make sure that it is intact, damaged, and that there is no partial collapse of structures. When entering an apartment, first remove all flammable liquids, medications and any other potentially unsafe substances. Water, gas and electricity can only be turned on if you have clear evidence that all systems are operating as normal.

5. When traveling around the area, stay away from explosion-damaged areas and areas marked with “unsafe materials” and “radiation hazard” signs.

Note!
Having a radio with you to listen to official messages from local authorities will be an invaluable help. Always follow what you receive, because the authorities invariably have more information than those around them.

An electromagnetic shock of low power is not likely to cause gigantic destruction, demolishing everything in its path, like, say, the one that results from a nuclear explosion. You can create a low-power push at home.

Instructions

1. First, get a film camera that you will not need in the future, preferably one with a flash.

2. Put on gloves and begin the process of discharging the flash storage capacitor. Using insulated pliers, take a 0.5 W resistor with a resistance of approximately 1 kOhm and short-circuit the capacitor with it for 30-40 seconds. After this, short-circuit the capacitor using an insulated screwdriver for another half a minute so that it is completely discharged.

3. Make sure that the voltage in the capacitor is no more than a few volts. If necessary, discharge it again. Make a jumper on the end of the capacitor.

4. Now start discharging the capacitor in the low-capacity circuit - the synchro contact. To do this, wind about 200 turns of insulated millimeter wire around a dielectric coil with a diameter of 5-6 mm. Cover the top of the winding with electrical tape.

5. Connect the frame with the winding in stages with the flash storage capacitor. If your camera does not have a flash test button, you can connect a bell button in parallel with the sync contact.

6. Make holes in the camera body in order to bring out the wires from the button and the frame with the winding. The holes will prevent pinching and breaking of such important wires. Now you can remove the jumper from the flash storage capacitor and assemble the unit.

7. Take off your gloves and put batteries in the camera. Try turning it on while turning the flash to the side. Wait a little while the capacitor charges, and insert a screwdriver with an insulated handle into the frame with the winding.

8. Carefully, holding the screwdriver so that it does not fly off to the side, press the button. You should have an electromagnetic shock that magnetizes the screwdriver at the moment of the flash.
