Introduction: EMP Generator

Picture of EMP Generator

This is a easy, portable and cheap DIY project to make a electromagnetic pulse (EMP).

Follow the few steps and you got yourself your own EMP to disable or destroy electronic devices (this EMP is only strong enough to destroy a calculator).

Step 1: Schematic

Picture of Schematic

I made a easy to follow schematic of the device.

basicly it`s just a coil thats connected to the capacitor whit a switch on the positive wire.

I used a DPDT switch to arm and fire it. If I turn the switch to the right than it charges the capacitor, in the middle it´s off and to the left than the voltage goes to the coil.

Step 2: Parts & Tools

Picture of Parts & Tools

For this project you only need 4 parts (thats what I used)

- DPDT switch, I would recommend using a plastic switch so you won't get a nasty shock.

- Thick isolated copper wire.

- Disposable camera.

- Some wires


- Soldering iron.

- Soldering tind.

- Desoldreing pump.

- Tape.

- Toilet paper roll.

- Cutter plier.

Step 3: The Coile

Picture of The Coile

Making the coil:

Make a small hole on the top of the toilet paper roll and stick the wire thru the hole like shown in the picture.

Take the copper wire around the roll 7 times.

Slide the copper wire off the toilet paper roll and tape the coile when you get it in its shape.

Step 4: Removing & Soldering

Picture of Removing & Soldering

Open up the the camera and take out the circuit board but be careful if you get your fingers in the wrong place than you are going to get a nasty shock (if the capacitor is charged).

Remove the flash and the switch for the flash.

Solder 3 wires to the charge switch as shown in the photo and just follow the photos and the schematic.

Step 5: Finish

Now you are ready to do whatever you need a electromagnetic pulse for, you can make a nice enclosure for it to. I am not responsible for any destroyed phones or damage!

How would I go about making this thing directional??

DiegoT62 (author)2017-04-30

Hola como puedo hacer para ampliar su poder asta un alcance de 50 metros aproximadamente? gracias

Demonstrations (see YouTube Videos) indicate this device works on devices only in very close proximity -- in some videos only when this EMP device is literally IN CONTACT with the "EMP-ee". How can its power be actually TRANSMITTED?

Shupedewoop (author)2017-01-12

It works by charging up the capacitor then releasing all the stored power in one short burst

Shupedewoop (author)2017-01-12

To all asking about gauge of wire, try something around 26 thats what i did, i also made a massive coil though

manolis.kasos (author)2016-05-06

what is the diameter-gauge of the wire?

i would use something thin but not too thin, try 26 guage

Bpgas01 (author)2016-02-27

You could use one charging circuit connected to a bank of capacitors connected in parallel. But if you make it too powerful, the EMP will release everythinh in the spectrum from radio to x-radiation. So if you are in the blast radius, you might end up with cancer.

Note: if you do make it powerful. I recommend using a directional antenna

Shupedewoop (author)Bpgas012017-01-12

false, the energy released from this is and can only be a electro magnetic pulse,

pumping more power into a microwave wouldnt give you the amount of radiation, so why would this do that, and its not even on the spectrum related to radiation

togdy (author)Bpgas012016-07-03

It's just not the truth. Or you've got no idea what you're talking about.

PhilieBlunt (author)2015-11-24

sorry if this is a dumb question, but where is this getting power from? i dont see any kind of battery or anything on this circuit board...

PhilieBlunt (author)PhilieBlunt2015-11-24

Oh duh, nevermind, i see the battery in the first pic now, yup im an idiot

mdevesh (author)PhilieBlunt2016-12-16

Never mind me too

ibenkos (author)PhilieBlunt2015-11-24

It might be a bit hard to see but the battery is under the capacitor and its not in the photo under the building photos.

PardalP (author)2016-11-29

Making a bigger one is for when there is someone walking with the car glued to their back. Just give a pulse to destroy the electric motor.

I have a suggestion that would offer up a MUCH more powerful EMP generator for fairly little money. Go to any farm store (Rural King, Tractor Supply) even online. Buy a livestock electric fence energizer. I have one to energize my fence on 5 acres, capable of energiing up to 5 miles of fence. It puts out 20,000 Volts. There are bigger units that will energize 10 miles of fence, I think generating ~40,000 volts. There are even solar powered versions that have a small 12 volt battery pack and a couple solar cells to keep it charged. THAT would be the basis of a self-contained unit. The

patrebates (author)patrebates2015-10-12

The cost for a basic 5 mile fence energizer is about $40. The solar versions are more expensive because of the battery pack and solar cells. Still, not too expensive (maybe $150) for a nice EMP generator. You can HEAR the EMP off these fences in normal operation on any AM radio if you are within about 100 ft of a short in the fence. The spark jumping to a nearby nail or tree limb produces a clock-like blast of static on your radio, and that's not even trying. Put the juice through a coil and you could get a nice, intentional blast.

ibenkos (author)patrebates2015-12-11

So if i have a 10 mile long fence and make a BIG circle with it, than hook it up to the generator. There will probably be falling airplanes down around me!

davidphillippina (author)ibenkos2016-11-16

yup takes all kinds to make the world go around

DefinatejustGeorge (author)2016-09-04

does anyone know what it would take and where to find one that has already been built to operate normal household appliances, stove, fridge, furnace fan, central air. 2 computers, 2 TV's and several say 10 household lamps. available to a Canadian address and how much $$$$$$????

DIY4895 (author)2016-08-28

Gathering supplies for this build... Do you know what gauge the copper wire is?

moscaj made it! (author)2016-08-17

Awesome project! I made a circut with an on/off switch and a button to fire. (Coil is on the bottom, under the circut board.)

thatguy231 (author)2015-09-23

How powerful is this version of EMP

ibenkos (author)thatguy2312015-09-24

I destroyed a calculator with it but i dont think it can destroy anything bigger but I would not recomend trying it on a cellphone.

Ryz3D (author)ibenkos2016-08-06

As far as I know, almost all Cell Phones have protection against EMPs (Metal Plates over the Circuits) so it won't do any damage on low Power. And on high Power it simply re-boots, that's all. So to do serious damage to a Phone you need a really, like really, really strong EMP.

manolis.kasos (author)2016-05-06

what is the diameter-gauge of the wire?

ReconDestroyer_2 (author)2016-04-04

what is that blue 3v motor looking thing ?

0r4cl3 (author)ReconDestroyer_22016-04-15

I think its a small transformer. Bigger ones can run around more voltage.

ReconDestroyer_2 (author)2016-04-04

is it by any the switch ?

ErduanB (author)2016-02-25

So is the capacitor only needed on the curcuit bord?

DylanJ15 (author)2016-01-25

Would this be cheap substitute for a radiofrequency cavity? I am accelerating electrons using an anode and cathode right now but I was wondering if I could do it with a series of these EMPs in a vacuum tube? If not does anybody know how I might build a substitute to a radifrequency cavity? Thanks!

Darkraisisi (author)2015-12-12

well this look so amazing that im already halfway making the bloody thing , but now im at the part were i need the dpdt switch , the best switch i can find is rated 250v DC would that be enough becauce the flash capacitor 4(2) 9y or 330v as i read somewhere

ibenkos (author)Darkraisisi2015-12-12

The switch will work, I have the same kind. But you might want to be careful because it might come some sparks when you turn the EMP on, thats happening with me.

Darkraisisi (author)2015-12-12

how would you do it if you paired another circuit in parralel to double the voltage output ? or could you just buy an extra flashcapacitor and remove the original and then wire them both parralel?

ÁdámS66 (author)2015-09-15

Would more copper wire make it stronger? Or a better power source?

ibenkos (author)ÁdámS662015-09-15

You need to supply more voltage to the coil if you want it more powerful, maby two disposable cameras.

patrebates (author)ibenkos2015-10-12

And here's a BIGGER solar powered, with battery, fence charger for energizing an EMP coil:

Here is a powerful, portable power source designed to produce 7kV, only $100:

milkcartonkid (author)ÁdámS662015-10-03

how big are you wanting to make it, I could probably give a little advice.

KevinG40 (author)2015-09-26

what else can you use besides a camera

milkcartonkid (author)KevinG402015-10-03

I didnt look to see if it explained why the camera works best or not. the disposable camera works the best for small emps like this because literally the only modifying that needs done is to

1) remove the flash bulb.
2) connect the coiled wire to the flash bulb's wires.

now you hold the button on the camera down to charge the flash. when its charged you hit the button that would normally be used to take picures. and it goes off. for small applications its the best

Treker2 (author)2015-09-17

You should put a warning about the high voltage stuff.

gravityisweak (author)2015-09-16

It would be cool if you could put a little info in here about what EMPs are and how they work. Would electronics that make an EMP destroy themselves?

ibenkos (author)gravityisweak2015-09-16

I explained a little bit what it does. EMP destroys itself? I haven't fought about that, I gess it can be destroyed if you place the PCB on top of the coil.

JemChalweDoPorzygu (author)2015-09-15

Can it destroy shop ant-theft protection?

It is so wrong that your profile pic is a black guy, can't stop laughing

Fast! Go to the ophthalmologist because there's something wrong with your eyes.

I dont know but i dont think so
