Imagine that you have some kind of device that can disable any electronics at a distance. Agree, it seems like the scenario of some kind of science fiction film. But this is not fiction, but quite a reality. Such a device will be able to make almost anyone with their own hands, from parts that can be freely obtained.
Electronics Shredder - Electromagnetic Gun

Device description

An electronic shredder is an electromagnetic gun that sends powerful directional electromagnetic pulses of high amplitude that can disable microprocessor technology.

Shredder Principle

The principle of operation remotely resembles the operation of a Tesla transformer and a stun gun. An electronic high-voltage boost converter is powered from the battery. The load of the high-voltage converter is a series circuit of a coil and a spark gap. As soon as the voltage reaches the breakdown level of the arrester, a discharge occurs. This discharge makes it possible to transfer all the energy of a high-voltage pulse to a coil of wire. This coil converts a high voltage pulse into a high amplitude electromagnetic pulse. The cycle is repeated several hundred times per second and depends on the frequency of the converter.

Instrument circuit

In the role of a spark gap, one switch will be used - it will not need to be pressed. And the other for switching.

We take the case and drill holes for the switches. One from the bottom, the other from the top. Now make the coil. Wrap around the perimeter of the body. We fix the coils with hot glue. Each coil is separated from each other. The coil consists of 5 turns. We collect everything according to the scheme, solder the elements. We insert an insulating gasket between the contacts of the high-voltage switch so that the spark is inside and not outside. We fix all the parts inside the case, close the case cover.

Safety requirements

Be especially careful - very high voltage! Perform all manipulations with the circuit only after disconnecting the power source.
Do not use this electromagnetic shredder near medical equipment, or other equipment on which human life may depend.

The result of the magnetic gun

The gun famously knocks out almost all the chips, of course there are exceptions. If you have unnecessary electronic devices, you can check the work on them. The electronic shredder is very small and fits comfortably in your pocket.
Test on the oscilloscope. Keeping the probes at a distance and not connecting, the oscilloscope just rolls over.

    What voltage output coil? 1000 kV or 400 kV?

    A piezo lighter for a gas stove will do just as well and no need to invent anything.

    When checking the microwave in reflection, the camera on which they were filming is visible ....

    Well, the camera did not go down;)

    I recalled an old joke:
    Professor I am a universal solvent.
    You're lying my friend
    ??? why
    And in what you store it?

    Playing with a kacher is a bad idea, it also famously affects the body.

    He laughed. They’ve divorced one hundred percent. The chips are knocked out, and the oscilloscope works, although there is a sensitive amplifier at the input, as well as a working camera. In general, if you poke a shocker at electronic elements, you will also get such an effect.

    But what if the voltage is increased to thousands of volts, for example. And radioelements under such power to adjust. Well it will be possible to disable the entire area. Maybe of course not the area. But in a radius of fifty meters it should definitely work
