EMPs (Electromagnetic pulse) are quite popular in the world of science fiction. Wouldn't it be cool to have one of your own? That's what I thought when I started building it.

I wanted to make an EMP which will be portable and which can be hidden under full sleeves( That's naughty!). If you have the right parts, you can build it in no time. If you don't, you're in trouble.

WARNING: Not for children under 15 yrs of age :D

Well seriously, If you get a shock it'll shake your spine. These capacitors are really powerful. So please be cautious while handling the circuit.


Step 1: Step 1: The absolute necessity

An old camera circuit, doesn't matter whether its disposable or not is absolutely necessary. If you don't have one, its not that tough to make one, but it'll take lots of time. An alternative way is to use the circuit of a zapper or a separately sold camera flash.

I used the circuit of a 15-yr old camera. Just had to take out the circuit out of it. The circuit runs on a 3V battery system.

The reason I used a normal camera circuit in place of disposable ones is that the capacitor in a normal camera is much more powerful than the disposable ones. If you use the circuit of a separate flash, its even much more powerful than the normal cameras.

Please be careful while taking out the circuit. The capacitor might still have stored charges.

<p>couldn't you just ideally make it easier on yourself and use a hand held taser and fore it at the car? Now there's science.</p>
<p>so what's the range of this? in todays world full of illegal drones we need this to stop the possible danger illegal drones could do</p>
<p>Sigh..... drones aren't illegal the government has made no law regulating drones and you can't own the airspace even if it is above your property..</p>

<p>This is a handheld emp Devce, made for concealibility not range. Something 3 times this size might be able to take out a calculator 5 feet away. Second, there is no such thing as an &quot;illegal drone&quot;, and if there was a hacked military class drone flying over the US we would have bigger problems. If you are referring to commercial quadcopters, as a pilot myself I and others I know fly more than 30 feet above the ground essentially all the time. You would be better off with something like a slingshot, considering an emp with a range large enough to take out a commercial quad would also wreck every electronic in your and your neighbors homes. If you are worried about predator drones, invest in a nuclear missile to detonate in the atmosphere, creating an emp large enough to knock out half of America. Another great anti drone tool is an automated surface to air missile launcher. These can be sourced on the deep web or from certain Islamic extremist groups. However, if you are feeling ambitious and want to get up close and personal with the military drone flying a few thousand feet over your home, the AH-64 Apache attack helicopter is a great vehicle for conducting aerial combat against MQ-1s and F-450 quads alike. Good luck!</p>
<p>So how long is the range? a foot? or do i need to touch the object to damage it?</p>
<p>That's why I want to make one. Take out drones flying over my property.</p>
<p>Good luck, it'd take more power than your house uses all day to effectivly take a consumer UAV down. </p>
Is this powerful enough to take out a laptop if you're standing next to it?
<p>These capacitors are in many different devices and are pretty cheap. I want to build one to see if I can take out hobby drones that fly over my yard, anonymously. If it falls in my yard, I can then file charges. I don't like neighbors spying on me and they keep getting away with it.</p>
bad news,this thing can only range around 2-4 m max<br>even if its stronger a lot of those drones have emp sheild like mine
<p>with the camera capacitors, yes. But the capacitors in my possession, much larger. and the battery is a 12v. Robotics sized battery too. I still need to find out what the radius for mine will be.</p>
<p>2-4m is exactly what i need. this is gonna be fun.</p>
<p>hello! As a quadcopter builder and pilot I feel I should inform you that in order to actually spy on you, quads (drones) have to be within a few feet of your window, and the majority of them do not even record. If you were really paranoid about people spying on you, why do you carry around a phone with to cameras on it, and probably at least another one on your laptop or tablet? And second, no judge would take that case. That's silly. Would you sue if a baseball fell in your yard even though you hit it there?</p>
<p>I have separate, VERY large capacitors, is it possible to swap <em>them</em> into the EMP?</p>
<p>I have access to lots of resources from my tec class. Getting insulation wont be an issue either.</p>
<p>also, can I use tetrix 12 volt rechargable batteries intead of AAs?</p>
I don't understand the steps I only got this far with the camera, can anyone help?
Do you have a video you can direct me to? Thank you
The creator of the work said it might effect his camera/phone
<p>Guys, please understand!!! Making a video demo is almost impossible...it would damage my phone/camera...</p>
I really did not understand the steps, can you tell me the steps in a mother way (if possible ) please and thank you
rap it with aluminium coil
no it wont take a look on youtube emp generator they recorder and your coil is smaller
and you can use zoom if you that afraid
<p>you should meassure the range of the EMP before anything, be aware that an EMP could shut down SOMEONE&acute;s peacemaker thus probably ending bad (at least) or damage any other important device (traffic lights, car electronics..). That being said, awesome project.</p>
<p>Hey guys, I just read the conversation and wanted to respond to what Lean04 said in his last statement. I have worked as a healthcare professional for the last 22 years and wanted to give my 2 cents towards the pacemaker comment... Actually thats completely wrong when you said that an EMP will stop a pacemaker. Can you seriously imagine thousands of people just dropping dead when they walk to close to an MRI machine or a strong Neo-dynium magnet in a speaker or something of that sort? Not to mention people inadvertently making &quot;lethal&quot; spare parts created EMP's? Well needless to say, thats not possible thank God! What actually could happen though in a rare scenario like that is that the pacemaker goes into an 'Emergency Demand Pace Mode'. What this 'Demand Mode' does is put the pacemaker into a blind beat pattern. IE: it just paces at a very regular pre-determined fixed rate that is adequate to meet the normal blood pressure needs of that particular person. Most everybody that has this happen has absolutely no idea that this 'back up mode' has even occurred to their pacemaker. They usually find out when they go see their cardiologist for their next M.D. appointment and have their pacemaker &quot;queried&quot; by the transdermic computer. And the doctor will read on the pacemaker read out information that some sort of an event occurred during this particular date and time. He then will just simply re-program the pacer to enter it's normal operation program. And then that is that, and no one is the worse for the wear. So anyways, i just thought i'd throw my 2 cents in and give you some real life information. That way you don't have to worry about rumors or non-factual beliefs that might needlessly make you worry about making an actual kick-ass hand held EMP! - Carry on Gentelmen -</p>
<p>An EMP *WILL* in fact damage all electrical equipment including pacemakers. This device probably lacks the power to stop one, however, lets not try it. An MRI creates a strong magnetic field that, should a pacemaker enter it, will violently remove the pacemaker from the body, so damage to any electronic components would be the least of your worries. Since you've been a health-care professional for 22 years, I'm sure you can agree they keep patients with medical implants far away from MRI machines for good reason.</p><p>And as for neodymium magnets, they create such a weak field that the only damage they could cause is erasing the magnetic data stored on credit cards, if the card is held very close to the magnet and speakers that do emit a field of significance will definitely be shielded to protect from the interference created.</p>
<p>Sorry, wrong again. A pacemaker would not be ripped from a person's body in an MRI, it would vibrate just like neodyminuim sensory implants. </p>
<p>pacemakers are shielded quite a bit and all the emp would do if close enough is the same thing as placing a magnet over it, shut it down temporarily.</p>
That is the issue. If a person need the peacemaker to take over the rithym (low heartbeat rate, for example a drop below 40 bpm) and it is not working, a few minutes are enough to cause death.
<p>Maxv2 you are so smart lol good info by the way idk if your a guy or gal so sorry if I mess this up but he's right it would be scary to think if I had a pacemaker and I went to the doctors then bam I drop dead from an MRI or CT scanner but an EMP is jest a little different then them so who know what would happen I mean EMP are suppose to shut down electronic devices so it some way's it could stop a pacemaker not saying it will but if that was your intentions then you could make one do so but i'm sure that's not what your trying to do idk a lot about this stuff so I don't want to give wrong info so im jest going of an article that I read and some stuff I looked up but yes I think it so cool to have one I know I would use it but that would be for fun not to harm so remember to know what's around you so no one get's hurt </p>
One thing about an electromagnetic pulse, when it pulses is pushes out everything in the range of radio to x-radiation. So if you give it too much power, and if you are in the blast radius, you might end up with cancer
<p>I think such a device fitted to a passenger jet would protection against the use of drones to bring down airliners.</p>
<p>can provide circuit design ??</p>
<p>Why use a dispoable camera? You can just *buy* the components through a site like digikey or mouser - and cheaper too.</p>
<p>you could improve on this design by :</p><p>1. not attaching it to your arm thus causing yourself extensive burn/shock risk (plus it's not very concealable anyhow)</p><p>2. using a focused magnetic field to direct the output. you could do this with two ring magnets. i'd try one behind the coil one above, you would have to frame them lest they touch the coil.</p>
Actually, i am a doctor. Patients with peacemakers aren't allowed to get an MRI scan or be in the scanner room, as well as microwaves and strong magnets. In surgery a special device must be used to avoid peacemaker malfunction due to the electrocautery electricity. Also, i talked about traffic lights or cars that might malfunction and crash if they receive an emp...<br>That being said, i only suggested to measure the range, not avoid using it. Safety first!<br>PS: if i had a peacemaker, i wouldn't like to test if an emp shuts it down..
Can it only be done using cameras?
<p>next stop wall street</p>
<p>NO if you do the stop after that WILL be Guantanamo bay federal prison</p>
can i know the use of this build please!
<p>its to permanently damage electronic devices with integrated circuits. </p>
<p>What is the range on this ?</p>
It looks like the walkue talkie antenna isnt needed, as you can place the emp coil on your hand with the strap, then run a longer cable down your arm and into the pocket of a jacket, make a plastic case for the circutboard, and wrap the coil in one layer of electrical, so the device will be less visible.
<p>perfect, just what i need for my science fair</p>
<p>does anyone do this?</p>
