Introduction: How to Make EMP Gun !

Picture of How to Make EMP Gun !

Hello my dear friends. EMP is one of the most popularly used sci-fi gadget in movies. It is not only a science fiction concept it is real and you can make it from very common household items. So today I am going to show you. EMP gun .

EMP device stands for electromagnetic pulseEMP devices can damage any electronic devices or disturbed there working. Please be careful while making this EMP Gun. Also make sure that use of EMP is illegal in some areas. I am making this device for pure educational purposes to know the effect of EMP on day to day consumer electronics. Please do not use for destructive uses i will be not responsible for any damage.

See This EMP Gun In Action !

Step 1: How It Works !

Picture of How It Works !

This EMP Gun works on the principle of Electromagnetism EMP devices use high voltage generator that will convert 3.7 volt into few thousand volts voltage is further amplified through an passive voltage multipliers then it passed to a electromagnetic coil with the help of spark gap This coil that will produce high frequency electromagnetic pulses. it is possible to increase the range an the output power.with the use of capacitor connected to a coil will increase the power output of an emp. You can see in my demonstration i showed Watch , stopwatch,RFID tag,memory cards nothing got survived .

The Intensity magnetic field created by EMP gun get Induced into the circuitry of this electronic devices which basically induces the voltages all over the circuit. So you will never know what will happen. Either the device memory will reset. or It will permanently damage this device. So be careful. Keep your electronic devices far away !

Step 2: Things You Will Need !

Picture of Things You Will Need !

★☆★ Buy Parts from your online local store ★☆★
1) Bug Zapper Racket

2) Toy Gun

3) Tactile Button

4) Soldering Iron

5) Wire

Material You Will Need

1. A Bug Zapper Racket , usually used to kill mosquito's , We wiill use its high voltage generator.

2. You Will Need half meters of 1sqmm thick piece of insulated wire to make an coil , alternately if you want more range out of it you can use enameled copper wire and as many turns you want .


1. A Soldering Iron

2. soldering Wire

3. Bit of a time with patience ! Please Wait For The gif's to load in this instructables !

Step 3: Let's Make EMP Gun !

Picture of Let's Make EMP Gun !

1.OK friends so start by taking apart your bug zapper racket using your screwdriver ,inside you will find. a high voltage generator circuit.We are going to use this high voltage generator circuit along with the battery.

2. Now take 1 sq mm wire. Make a coil as shown in the picture

3.In my design I removed the output capacitor to limit the output power ! but you can Keep the capacitor as it is.

4. Solder one output wire of coil to High Voltage generator and form of spark gap using other output wire as shown in the picture above. you may need to fix the wire at a distance , Keep in mind that this gap decides output Frequency of your EMP gun closer to wires are higher the frequency will be and vice-versa so you may need to tweak the distance In between them ,I found that to 1 millimeters distance work best for me.

5. OK To make a Handle for EMP Gun I am going to use my old Toy Gun as a handle and Stick all the parts together with bit of a hot glue .

6. I also extended the push button switch so i can use it as a real EMP Gun !

Step 4: Please Do Not...

Picture of Please Do Not...

Please Do Not... point the gun at anything , it can cause real and permanent damage .

Instead You can Watch me testing this gun . be safe and act safe have a good learning !

As I see it, this device will be only appreciated by terrorists,
criminals and nasty little vandals who enjoy causing trouble to other

Please bear with me if I am missing the point, but why would any normal decent constructive person want to make a gadget that does nothing but destroy other gadgets ?

i think its good

you can learn scientifiacally and think that anything's possible.......

it is good

RogerD5 (author)ElectroFrank2017-08-22

Actually, the government itself uses EMP guns to take down cars, to fry laptops carrying sensitive information, et cetera. You are essentially calling the government "terrorists, criminals, and nasty little vandals who enjoy causing trouble to other people." I mean, it may be just me, but I don't think you should comment your worthless, unconstructive opinion if you are a "normal decent constructive person".

BlakeM43 (author)ElectroFrank2017-06-03

I want to make one just as an experiment. I have no malicious reason to have one I just think that it is pretty cool. I'm not saying that it couldn't be used for bad reasons, I'm just saying that as a project it could be fun.

Bog6 (author)ElectroFrank2017-01-19

LOL... dont worry this gadget is very weak and can only do harm to little calculaters and such.

its just a science experiment

Oncer (author)jedisalamander2017-01-18

To you maybe. But, really, it's just a weapon.

dstech (author) Oncer2017-01-18

I think clearly people need to be EXTREMELY careful with stuff like this. However, that being said, just like people building tesla coils which can be very dangerous, it does also seem like a really cool experiment...and there is some merit in understanding how things like this work. Still, of course I would never advocate using this for malicious purposes or in any setting where there could be someone you are unaware of that has a pacemaker or other electronic medical device implanted...again, extreme caution and awareness is needed.

Will emp become stronger if number of coils are increased

tatebullrider (author)2017-03-30

I really like the idea of building a larger scale E.M.P generator for testing purposes. I have been thinking of using a MOT as a high voltage source. However, when I was doing some research, I found that the most common way to generate an electromagneticpulse is via a capacitor bank. Could I use nothing more than a MOT instead of a capacitor bank?

gianmurray (author)2017-03-15

i cept mine in the handle

alanjamesblair (author)2017-02-17

Oh fun! Must print out this I'ble for the apocalypse. I don't trust myself to have one of these while laws and such are still in place, but when society collapses, I'll be in business. Thanks!

iceng (author)2017-02-13

Only a fly zapper and is no more an EMP then a boombox.

zposner (author)2016-12-08

That's awesome, what would happen if you did it on a phone!

MayankJ10 (author)zposner2017-02-13

Just try!

ThomasK19 (author)zposner2016-12-11

Just try it with your phone and enjoy.

Oncer (author)2016-12-13

What about pacemakers? You could seriously injure or kill someone fitted with a pacemaker with a device like this.

MayankJ10 (author) Oncer2017-02-13

That's True.

John T MacF Mood (author)2017-02-13

You CAN make these, but should you? My answer is no.

For one, if you discharge one near someone with a pacemaker and you don't know it, it could kill them. In a car, it could cause the deployment of air bags, or radical braking by the computer controlling the car. The possibility for serious harm or death is too high.

For two, any device that has a spark gap has to be adequately shielded, or it is illegal under US FCC law. Spark Gap transmitters were outlawed many years ago by the FCC, and by international treaty by the ITU. The RFID tags, another illegality.

Nice work, but just because you can do something, it doesn't mean you should.

It will only happen for a bigger device, This one is too small for that but yes these things are dangerous.

John T MacF Mood (author)2017-02-13

And your USB killer, does it allow the PC to boot after removing the "killer" dongle, or will it have destroyed something critical to operating the PC?

LiamOSM (author)2017-02-13

I wonder if this would be able to erase the RFID tags found on clothing in stores. If the tag was erased, I wonder if it would still trigger an alarm when passing through the sensor gates at the doors.

Just a theoretical question of course.

baecker03 (author)2016-12-11

by shorting the circuit, you will be introducing more stress on the other components in the circuit. also, would be careful to use properly insulated wire.

vin_niv (author)baecker032016-12-25

its okay if there's diode in there

vin_niv (author)2016-12-25

is it rechargeable?

tatebullrider (author)2016-12-19

Yup... definitely building one of these Lol.

UnclTodd (author)2016-12-14

I wonder if this little monster has the power and range to do a super-clean erase on my old 3-1/2" floppies? Yeah, I still love my ancient (2002) Sony Mavica camera, but my equally ancient floppy drive often takes several tries to reformat my floppies!

doodasi (author)2016-12-12

That's just great! Now I need to make a much larger model, and put it on an old harley davidson ironhead with a points ignition system, and zap every cop, and every car I come across. I will be unstoppable. Seriously though. This is a very cool very evil device. You just wait and see. Kids from all over will be making this and zapping cell phones all over the place.

Chrome98 (author)2016-12-11

please elaborate on the spark gap. you said "Like in the picture" but I couldn't find any pictures clear enough to see a gap anywhere.

zazu_247 (author)2016-12-11

So, is it directed?
