Introduction: EMP Generator Schematic

These are my plans for an EMP Generator.  It uses flash circuits from disposable cameras to power the coil. I plan to make an instructable of it soon. Leave me any comments or tips. Thanks.

The parts list is as follows:

1project box
3 flash circuits (from disposable camreas)
3 AAA battery holders
1 9v battery clip
1 9v battery holder
1 390 ohm resistor
1 red L.E.D
1 green L.E.D
1 12 DC PC relay
2 L.E.D holders
5 momentary switches
2 on/off switches
wire
1 iron core coil
1 momentary switch (2 contacts)

The small diagram on the back is an alternate firing setup if the momentary switch with 2 channels is not available.

It would require another relay, momentary switch and 390 ohm resistor, and inexplicably a blue LED.

After looking at the original I am actually impressed with the elegancy of the design. Not bad for something I drew in class :)

what AWG did you use and how many windings does your coil have?

what the use of the emp device ?

ewcrew (author)adark2013-12-18

An EMP lets out an electromagnetic pulse. It will knock out any near by electronics (temporarily) and could melt the wires if they are strong enough. The American military have been doing research into them because an EMP could be used to take out an underground bunker without killing anyone. Also a nuclear bomb would cause much damage to the surroundings. If you think about it though, a nuclear bomb is an EMP, a NEMP (nuclear electromagnetic pulse) to be precise, because gamma rays from the nuclear blast knocks electrons out of their orbits. The electrons form an electromagnetic pulse which has a range varying on how high up the NEMP is. If the NEMP is on the ground the explosion has a larger range than the EMP but in the air (e.g. 2 miles) the EMP would out-range the blast. The EMP would be strong enough to melt electrical wires that weren't protected by a grounded Faraday cage/

I don't mean to be unkind but I can't read your schematics. If you used a computer to draw it or made it bigger so I could read what you wrote it would be so much easier

I could you please explain to me what would cause this not to work. I would like to make one and get familiar with EMP's cause when I get older I want to design weapons. I need to know how to make it work.

author
nickhaik1 (author)2013-09-02

XOIIO, just read your comment, I made it, not as hard as your plans but simpler. I'll post my design soon. It's easy, maybe a bit dodgy but it works perfectly.

author
nickhaik1 (author)2013-09-02

There is no point for switch 8. Maybe to see that you've just fired the thing but nothing else. Thanks anyway cause this helped me finish my research. Post your finish product

Please let me know if someone can help.

I'm not an electrical engineer or even know a lot about electrical circuits or anything, but I'd like to build an EMP if I can find some good plans.
It seams to me that an old CRT monitor would have some useful parts to accomplish this, no?

Jurassic (author)2013-03-23

So have you made an original yet?

author
XOIIO (author)Jurassic2013-03-25

No, I've long since abandoned this, it was an interesting idea but it wouldn't have worked, and I haven't gotten any messages about people making their own.

author
elliottclark (author)2012-08-03

would it be possible/safe to substitute the AAA batteries for higher voltage batteries to make the pulse last longer?

abadon (author)2011-11-21

Here's a hint to build a directional EMP device with a ton of power. Take a wire strand and discharge a high-capacity high-voltage capacitor through it. The result is that the wire strand will "explode" and will release a huge (supposedly in the megawatts) EMP wave. However, in order to make it more effective, it is best to "explode" the wire in a parabolic dish so that the EMP will be focused and directed towards a target.

author
XOIIO (author)abadon2011-11-21

Yeah, thats simmilar to some military applications. I have an array of 30 400v capacitors I made, I'd just need to find some wire that works well.

author
Nyxius (author)XOIIO2012-03-25

when the wire flashes you could try focusing it with a magnetic field. You could probably achieve higher efficiency by using it to limit broadcast frequencies. Just flashing the wire gives white noise.

EMP stands for Electro Magnetic Pulse. Simply put an EMP creates an intense but short pulse of EMI  (Electro Magnetic Interference). The power requirements nesisary to even disrupt electronics fro 10ft away are far beyond what is coming into you're house. To distrou electronics (the only way for it to last more then a few seconds) it would need to be many thousands of times stronger.

Think of it this way. A nuclear bomb creats an EMP wave but it's area of influence is much smaller then the explosion.

That being said it is possible that this schematic could yeald a working device but it would never be powerfull to disrupt a computv reseer 6 inches away. The only efect if any would be the loss of tv reception.

XOIIO (author)Vadimk2009-11-13

I don't want a really strong one, I mainly want it to be able to kill cheap watches or calculators nearby.

author
Nyxius (author)XOIIO2010-02-05

You could improve output using a capacitor array and voltage multiplier to increase the strength of the pulse by decreasing the pulse period.  You could also use a multi-coil array to store the energy needed in a magnetic field.   Use the increased voltage generated by the collapsing fields to power your larger coils.

Nyxius (author)Nyxius2010-02-05

also like trike said, the device will probably fry itself with all the feedback...one time shot.

author
tazerboy (author)Nyxius2012-03-25

put a diode with a high rating to dissipate the feed back

You should build a marx generator and connect the output to a coil.This device could be pochet sized and also completely wipe out electronics

author
Nyxius (author)Vadimk2010-02-05

this is true...military grade "directional" EMP generators have ranges of only several hundred meters, but have power requirements of several gigawatts of power.  The only way they can generate this much power and remain portable is to make the pulse width very short.

The air force has tested a small EMP generator that is compact enough to fit inside a AMRGGM missile (Advanced Medium Range Ground to Ground Missile).

i believe nuclear emp waves are not smaller than the blast area. besides already working one are already being made and they are alble to disrupt electronics. http://amazing1.com/emp.htm

author
Nyxius (author)petler4772010-02-05

This is true, modern military grade EMP bombs have ranges from< 1 mile to several hundred depending on where the blast originates and how high it is.   If the intent is to simply disrupt communications (& not to fry electronics) then ranges on the order of thousands of miles are possible.

Now this is all in theory, But for a large scale EMP device could you not use a modified version of Richard Willis's "power multiplyer" to achieve those Immense amount of required power. I started viewing this post to see if I could possibly make my kids have no power to there cellular phones with a push of a button.
