I Built A Military EMP Gun! (New Method）

#EMP #DIY #Tesla
I don't know why, but I love EMPs and EMP generators. In the last few years, I've showed you how to build all kinds of EMP generators. But there are a few methods which we haven't tested yet. And I don't mean EMPs generated by a nuclear bomb or a flux compression generator. There is another method ;)

Excellent video Leon, this build was super fascinating! Now I kinda want to make a flux compression generator...

Hello.... I've been experimenting with exploding wires for about 10 years. My current (no pun intended) setup uses a 100 uF/4KV oil-filled capacitor. The kinetic energy during discharge is about 800 joules which produces a very bright and very loud discharge, similar to a gunshot or large firework. I live within a residential neighborhood, and so I must attenuate the sound as much as possible so that my neighbors won't call the police thinking someone was shot! I recently got hold of an old satellite TV dish which I plan to use as a focused EMP generator. If I can excite an LC circuit at the focal point, I believe that I'll be able to transmit an EMP pulse several meters (maybe wishful thinking!). I'll let you know how it works after I build and test it. I love playing (safely) with this stuff!

Oh, by the way, PLEASE make sure that you have plenty of ventilation while vaporizing metal wires especially wires made of lead or other toxic metals. Breathing metal vapor is VERY bad for your health! Thanks.

I fell down the DIY EMP hole a few years back, but never knew of the exploding wire method.
Great video, i enjoy your content!

[flamescales]

So, basically you are just shorting the capacitor... What if attach a coil and use the emf to destroy stuff? I mean.. It would be fun ig

[mallardtheduck]

The silver wire exploding that glowing green was gorgeous!!! I have experimented with HV for a long time and I still get nervous around MOT's. Stay Safe My Friend...Good Job!!!

"it's not necessary, but looks cool"

You know you're building something awesome and doing it right when you get to say that!

I think it would be worth trying different thicknesses of wire as well. It is possible that the reason you are not getting a very strong EMP is because the wire is blowing too quickly, so it does not have time to establish a really high current (and thus high magnetic flux) before it is interrupted and collapses. I suspect there is probably a "sweet spot" for wire thickness and materials that will maximize the EMP output in this setup, which also likely depends on capacitor size, inductance, etc.

It would probably also be worth actually measuring the capacitor voltage before and after to see how much of the energy from the capacitor is actually being used when it fires (this would require disconnecting your power supply before firing the gun, and just measuring the capacitor voltage directly (you can use the discharge resistors as a voltage divider and tap into them to get a measurable scaled-down voltage reflecting the actual capacitor voltage)).

lol, I used to do this all the time testing Thyratrons, 40kv and 2x 20uf (40uf total) capacitor discharged through a second thyratron that switches the full energy to the wire within micro seconds, faster than a spark gap. There was never any "usable" energy for an EMP recorded during my time of testing (10 years doing it up to 5/6 times a day) The first thyratron has to fire in the primary site when it detects the arc in the secondary. To do this, the capacitor is fully charged and then disconnected from the source. Those oil filled capacitors can hold that charge for a year without bleeding down. They are about 3ft high, 6 inches deep and 20 inches wide, weight around 100lbs. The power supply is used in a 100kw transmitter running at 40kv plate voltage. and the Thyratrons original function is to short the HV if there is an arc detected on the line that feeds the tube in order to protect the tube and remove the energy available from the supply. 2 of them working in tandem are fast enough to protect a tube that would cost close to USD 150K . We only tested the functuon of the tyratron not the circuit so we dumped the condensator energy into thin wires and created basically the same as they used to do in old flash bulbs for cameras in the 60s and 70s only our wires were only a few inches long. I have been as close as a foot away from the wire behind plexi glass with all kind of sensitive equipment and never had a problem. We measure energies over a vast frequency range from about .5hz to 1Ghz. Btw, your parabolic mirror is only for show, it doesn't do crap at the frequencies the main energy wave is produced. It will do a little above about 1ghz, but the amount of energy produced at those frequencies is minuscule even in our setup. The noise we produced, well lets say it is quite loud and can scare the bejeezus out of some unsuspecting people even a few hundred feet away. Sadly, high power thyratrons are rarely used anymore as modern low energy power supplies are protected differently.

Voltage and amperage are crucial in generating the pulse .Also you have a conductor running across the reflector re absorbing the energy being created it will produce counter emf into your rectifier bank

[christopherleubner]

The easiest way to build one is a spiral line flux compresion generator. It does not use anything special, just a jelly roll capacitor with 8 to 20 extra turns in the middle well insulated as a spiral. It gets charged up and discharges with a fast switch like a spark gap. The current becomes a time compressed pulse of about 60nS because each turn halves the discharge time and multiplies the voltage by 2. Then have the discharge travel through a shredding element like one of those DTV antennas at the focal point of a dish and grounded through an inductor with all of it in transformer oil. The mode broadening by the antenna decreases the pulse time to less than 4nS 😲🤓😎❤

Straight out of the 2004 book "Electronic gadgets for the Evil genius" - First time I've seen it on YouTube though. One of those real expensive kits from "Information Unlimited" (If I remember right).

More Flashlamp than EMP but still cool. And I somehow like exploding wires with a capacitor 😁

[leonnoelspy]

I got a cap bank made from old soviet oil capacitors. They are from old radar equipment and had an initial rating of 10kV and 0.5uF. A friend replaced the oil for me and they are now tested to 110kV but you have to submerge them in oil for that. I only use mine up to about 80kV. Any more and it jumps over between the contacts. I never charged the cap bank that high though... 30kV is already loud enough to make your ears ring with ear pros on and you feel the shockwave. The cap bank has currently 3.5uF i think... works well for exploding 0.2mm wire. I never tried any other type of wire and all my cameras also still work but i could try it out again...

I'm learning how to build one of these for the AI Wars that are coming up assassin Bots you know the whole takeover scenario

[MonotonyTV]

*EMP Gun?* If something electronic has been hit by an EMP blast, is it damaged forever or will it eventually revert back to working normally?

[CharlieSolis]

Awesome video!

Personally I want to build one of the EMP devices that works from collapsing a conductive cylinder thats between a magnetic field. Using a small explosion to collapse the cylinder to have a smaller area which the change in area causes an induced current and results in an emp.

[petevenuti]

Another thought, use that compact fluorescent bulb *AS* a helical antenna (for the operating frequency of your target), the current and magnetic field should go up as quickly as vaporizing a wire could make it go down (because plasma).
If the bulb survives, maybe it could be used in repeated pulsing mode!

Well as a young electrician. I once was part of a rew that by accident t created ball lightning. All it took was two opposing 10 000 amp DC supplies and an oops on two wires. Also about 6000 volts . You can get the same effect with a submari e battery ... it is almost magical plasma churning about in a ball ...just floating hitting ground and gone ..Ah that few seconds of WTF will never be forgotten . Take care .

[WTF_BBQ]

I built a Van De Graaf generator couple months ago just for fun. It doesn't produce nearly the amount of power your EMP machine does, but it shuts off computer monitors nearby. I was quite surprised by this considering that the generator was poorly made and it was quite weak. It can only produce 1cm very skinny disappointing sparks. This would make it around 30kv. Despite its shortcomings, i was able to wreak havoc on computers. Watching your results makes me wonder that maybe it's not necessarily the wire exploding that produce the desired effect. My guess is that it lacks the high voltage or the surface area.

That first pull of the switch was hilarious! 💥 Great video and channel.
