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.

I SHOULD NOT BE HELD RESPONSIBLE FOR WHATEVER THINGS YOU DESTROY

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.

Step 2: Step 2: The COIL

I had to make a coil which won't cover much area because I had to fix the coil on the palm of my hand. If the coil is too large I can get a nerve-racking shock just my slight movements of my palm.

So, I took out a coil from an old SMPS circuit. I had extra copper wires. So I used them to make a more powerful coil.

Make sure that the winding of the copper wire is tight. Otherwise it'll be ineffective.

and the notes about pacemakers and the like ... valid point ... you can neutralize HAARP with an EMP I believe ... Japan should try this ... if Russia is not playing nice

You disgust us. No one wants you here. Or anywhere for that matter

How big on a FOA (Field of affect) does this have? I am guessing around 4 inches of effective and a little more for just a small magnet? Am I right on this?

I haven't signed into instruct ables in a looking time, but I remembered my passwird, and felt the need to ask a question about this. I thought toroidal shaped electromagnets kept their field pretty close within the boundaries of theach ring itself. I thought that's why a lot of employment designs use different coil designs, but I gotta say, it certainly looks effing sweet

I believe the magnetic pulse has a specific range. There are numerous videos showing how it works so no need making another, but it wouldnt ruin your camera unless you held it at a close enough range.

can we also use a transistorized emp.jammer??
spoocane2 months ago

i had the same idea im still working on it whats the trigger

BlitzK12 months ago

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

Be careful ignighting a copper wire (as that's generally what you are doing if memory serves right ) if it touches your skin you WILL get burnt ...

lean0410 months ago

you should meassure the range of the EMP before anything, be aware that an EMP could shut down SOMEONE´s peacemaker thus probably ending bad (at least) or damage any other important device (traffic lights, car electronics..). That being said, awesome project.

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 "lethal" 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 "queried" 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 -

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.

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.

another thing you might want to keep in mind is the "capacitor" it hold a charge, and you could get a nice jolt!!! from that if you touch that in the wrong way. If your working with these make sure you discharge them or you could get a hairstyle you don't want lol. but very good jab I might give this one a try myself. thank you.

on my emp gauntlet although its much bigger i used a 3 inch pvc pipe to wrap 12 awg wire around and found that the coil could be placed around my arm as the body of the gauntlet without sacreficeing range and power, while still being able to be concealed.

does it works??

Have you tested to see how effective it is?
S0uraV_DAS (author)  jzuwala motts10 months ago
Nah I didn't...have some old digital watches and calculators...but didn't feel like destroying something of my own...I will however try it on someone else's instruments whenever I'll get a chance....:D
please give us a working video :) can it shutdown a phone ? or caculator :P
sives princepsp10 months ago
wouldn't it be a little hard to videotape it.....
McClay14 sives10 months ago

hey, good idea, you could use an old fashion hand cranked motion picture capturing device :D nothin to interfere with there :P

bmarconi10 months ago
jwalker sr does have a point, this is probably ineffective. Since all you really did was create and electro magnet that flashes on briefly. its range is almost certainly small enough that having your hand on the object would have little or no effect. due to the fact that the further you get from a magnet the faster is pull decreases. It is an exponential relationship. And even extremely large and powerful electro magnets have ranges that are very short.

I commend you on your time & effort put into building and creating this ible but I do believe some facts of similar (with only a difference of magnitude) workings should be included in discussion.

The following is not intended to be given as an insult.

Honestly, I hardly think this would affect a camera recording a possible demo of the device, even at a couple feet away, let alone something you have your hand (the coil) immediately ontop of.

If you didn't already know, an atomic bomb will release a pretty destructive EMP when they explode. And even though it reaches a decent distance… you have to take into consideration the amount of energy involved in the explosion. I could be wrong but without googling it I believe I heard this EMP's range extends several miles. Although, with that said, just think of the ratio of energy involved to the range of the resulting EMP. Then think of 3vs and a couple hundred micro-farads / volts (300-400uf/v at most) cap being dumped into a rather small coil/transformer.

If it were this easy, we'd be seeing a whole lot of reports of cars, [security] cameras, stores, phones, tv's, houses, etc getting "mysteriously" destroyed.

••Also it would be most beneficial if the ible being provided was tested/proven, and/or a demo recording included, to work before being posted and eventually causing disappointment.••

To make an update, after the replies made to my original comment and searching some info it appears this ible device would more or less just create what is commonly called "interference" and is, by IEEE-SA (eg. Electrical Engineering Standards), taken into consideration when developing most electrical hardware.

In short, the interference generated from this device would already be protected against in your everyday electronic devices.

"If you didn't already know, an atomic bomb will release a pretty destructive EMP when they explode"
They release a pretty destructive everything lol.
I would exspect that their biggest "emp" like effect, is probably the fact that everything (electronic or not) within range is destroyed...

This is true hehe. I was hoping the "other" destructive force was universally known :) and was just singling out the secondary effect of the EMP.

The range of an atomic blast's EMP depends on the altitude the explosion occurs. The higher the altitude the longer the range. A nuclear device explosion at about 40Km altitude would generate an EMP that would affect the entire USA.

Thank you for that tidbit of info. And yeah, I should have been using the term (thermo)nuclear rather than 'atomic'.

Off topic: Pretty scary stuff to think about... I've heard some horror stories about how effective our (US) missile defense is; or lack-thereof.

lkrewson10 months ago
Couldn't you test its range by setting out cheap flashlights at different ranges and then turning on the emp and see which flashlight s mess up
sclark4510 months ago
to film it in use try a good video camera shoot at a 45 degree angle from behind you ....
most video cameras will zoom in a long ways and use a rental camera. ..if it dies go return it walk in all pissed that it quit and you didn't get to shoot your friends wedding. then ask for a refund of the rental charges. don't feel guilty about it. ..

Guys, please understand!!! Making a video demo is almost impossible...it would damage my phone/camera...

QEDyesca10 months ago

When you can, please post a follow-up video of the device in action.

S0uraV_DAS (author)  QEDyesca10 months ago

I can't make a video of the device in action, it would damage my phone/camera...

You definitely want to isolate all metal parts such as the contacts of the capacitor to reduce the risk of an electric shock. This can be either done with some shrink tubing or hotglue.

S0uraV_DAS (author)  nqtronix10 months ago
Yea I know....Thats why I have used insulating tape...for the capacitor contacts...I don't have hotglue...It really is a risk...

Well, then it's time to get a hotglue gun ;)
