Anyone know how to build something that wil give off a shockwave of EMP, so i could like wipe out a computer room, it will make people confused to see there computers fuck up. Thanks 🙂

I asked the same question a few months ago and got no answer.I saw detailed info before plans etc. but I didnt realise its potential and then didnt have much interest in it.Cannot find the site since.There somewhere though!

Go to http://www.amazing1.com they have plan/pre built emp generators

Thankyou very much, it looks abit expensive those 😛 I were just interested, if it were cheaper and simpler then maybe i would try it. Thanks anyway those.

Hehe oh brother.  🙂  An EMP generator with enough kick to fry semiconductors at a distance entails an awful lot of current, mind-bending voltages, and plent of arcing & power consumption.  These ones look to be the real deal, and no surprise they *are* rather expensive.  Anything shielded in a conductor (steel computer case, etc.) will act as a Faraday cage and ideally reduce even a large EMF to zero inside, protecting the electronics, especially when the case is grounded, as all CPU cases are (or should be) just to pass UL/CE licensing for consumer use.  As usual, the most exotic and cool-sounding “solution” is the most expensive, bulky, and inconvenient.  If you want to disable an entire room of computers… define “disable” more narrowly.  You could make them all useless for their intended purpose by just nailing their Achilles’ heel; their network hub or switch.

Something I saw as well was an EMP bomb using 1lb of c4 inside or around a solenoid.When it exploded it collapsed the magnetic field fast enough to form a one shot EMP pulse.

This is called a Flux Compression Generator, and also requires a timed discharge of current through the inductor just before the chemical detonation occurs.  As the detonation wave progresses, the metal tube shorts out the coil at roughly the same rate of propagation, progressively shortening the coil and lowering its inductance.  The result is an impulse of tens of thousands of amperes, albeit for a fraction of a second.  The coil eventually breaks, and the magnetic field collapses, radiating outward and inducing current spikes in every conductor the EMF impinges upon.

Okay, there is a big ass server in every computer room, easy enough to nail i guess, but what wiv???
Also, what does the term “spike” mean in electricals and computers, i have heard that alot in films and never have rememebered to ask someone. Thanks.

The Flux Compression Generator (bomb thing) seems kool, if only i could get the equipment required! I dont wanna completely fuck the computers, just wanna crash um and shit, electrical spiking sounds fun……explain.

A “spike” is a generic term referring to a high amplitude impulse of current or voltage.  The ideal impulse is modeled by the Dirac delta function, d(t), which has a value of zero at all times except for t=0.  The integral of the function (area under the curve) is equal to 1, meaning that at t=0, the value must be infinite.  There are no true real-world impulse signals, since they would require infinite energy, but it’s a useful model in physics and digital signal processing (DSP).  Such a signal has its energy concentrated at extremely high frequencies; as a result, the propagated electromagnetic pulse can defeat Faraday cages that protect electronic equipment, since their wavelength is so small.  The Faraday cage concept is used in microwaves… ever wondered why the waves don’t fry you yet you can still see through the door?  The perforated metal mesh contains holes that are significantly smaller than the wavelength generated by the magnetron, preventing them from propagating.

How would i “spike” something then, for example a PC? Ive seen it done in a film, or is that just another thing Hollywood has made out to be possible to make the film more interesting?

I heard you can make a emp weapon out of a microwave magnetron

— Posted by qube on 6:51 pm on Feb. 14, 2002

Mmmmm, wouldnt that would pose a danger due to the microwaves given off……or wont microwaves be given off???
Id like fire it and my hands would melt off 😀 and my dick shrivel up, nooooo! LOL!

Grrrr!!>>>!… Microwaves do not give off any radiation or direct heat!!!!!!!!!!!

— Posted by balor on 3:07 pm on Feb. 15, 2002

Well Sicopath a magnetron gives off a beam of radiation(microwaves).Its described in the “Poor Mans Ray Gun”.Its aimed at timber to burst it into flames by exciting the molecules to create heat(like overcooking a dinner drastically),aimed at plantlife to kill it instantly or aimed at a circuit board or a plastic cased electrical appliance to fry its electronic components.Microwaves can penetrate any material but metal stops it like it could pass through 6 feet of concrete but be stopped at a sheet of tin foil.I found looking at the rating of magnetrons in ordinary household microwaves that they are too small to be used effectively.In the book they talk of 4-6Kw microwaves while the ordinary microwave is about 800w

— Posted by qube on 7:17 pm on Feb. 15, 2002

Mmmmmmm, im sure the microwaves would be dangerous still. Be like an extra large mobile phone.

— Posted by Hergor on 1:05 pm on Feb. 16, 2002

so does anyone know a way to power up ordinary microwaves then ?

might be somehow cool/hot…

— Posted by qube on 1:07 pm on Feb. 16, 2002

I agree, how is it dun, and how do u control it!

— Posted by balor on 2:06 pm on Feb. 16, 2002

A for controlling it the beam is just like a laser beam in the way it is emitted from the magnetron so it can be aimed.As for powering up an ordinary microwave I dunno!An ordinary 800kv magnetron has a fan blowing on top of it to cool it and scatter the microwaves so it must be usually be running at absolute maximum possible output

— Posted by qube on 5:35 pm on Feb. 16, 2002

Okay, but does anyone know anything else that can be done with it? Like actually how it could be used in real life, rather than jsut thinkking about it. I CAN see it working, just its getting the mutha fucker to work! Is the fan just to scatter the microwaves, or does the magnetron get hot?

— Posted by pyroman on 10:18 pm on Feb. 16, 2002

the output of a magnetron has a full 180 degree span but of course you could control it with a metal cone. as for the power souce just take the one out of the microwave.

— Posted by balor on 3:13 pm on Feb. 17, 2002

The fan cools also as there is a filament in the magnetron.The microwave radiation doesnt exit the magnetron in a 180 degree radius but in a directional beam.As for the metal cone,it probably wouldnt work with microwaves as it would absorb the rays.Anyway you would think that you would have to have a small hole to maximise the output but microwaves probably wouldnt pass through a small hole because of its wavelength(like you can see through the metal grill at the front of the microwave but nothing passes through the grill.As for the power supply you would have to plug it in or a battery and invertor with a large enough capacity.

Look at it this way, it takes 3 to 5 minutes to make popcorn. The magnatron in the microwave oven is maybe 50% efficient at best. Some heat must be dissapated from the magnatron.  The highest power oven I have seen is maybe 1100watt. What is needed is something like you see in the Godzilla movies and a power plant to run it.  Microwaves have characteristics like light waves and can be reflected by mirrors  ( microwave dish ), or through a waveguide.

U were saying about a magnetrons 180 degree field…my friend made one and over came this by making an aluminuim wave guide which went over the emmiting end and made the waves directional. He also made one of those emp bombs you were talking about…aparantly…it took a radio out from about 15ft totally fried.

— Posted by Zambosan on 3:15 pm on April 2, 2002

I’m constantly amazed at how many imaginary friends people have… and how much amazing stuff they’ve done.

— Posted by qube on 3:55 pm on April 2, 2002

LOL so true, you took the words straight from my mouth…..lol!
