Destroy Any Device With EMP Jammer


Introduction: Destroy Any Device With EMP Jammer

About: Ideas Into Reality !

Imagine that you have powers to stop any electronic device, is it only possible in movies?

well here's the way to make an emp jammer (Electromagnetic pulse jammer)

This device sends high amplitudes of emp to destroy nearby devices, be sure to have fun using this, but be careful this jammer involves thousands of volts which can lead to heart attack or death even (if not used properly)

1. 32 gauge Magnet Wire

2. Plastic Project Box

3. Push Switch ×2

4. Some kind of glue

5. Hot glue (if you need)

6. 3.7 v battery

7. 7000 volt High Voltage Converter

Step 2: Connecting Togather

make a coil of 32 gauge copper wire with 5 turns connect an push switch (i call it spark gap) and high voltage converter in series with coil.

connect an push switch to control power to the high voltage converter .

Use more turns in the coil

You can kill a person with a pacemaker. :-(

Something like this would be great in a movie theatre

why higher voltage makes greater magnetic field? Doesn't the higher voltage mean lower current and consequently generates weaker magnetic field?(P = IV, also I can't fully understand how the spark gap plays in the circuit. When there is high voltage, electric can go through the spark gap frequently and that makes a pulse, right?

I believe the spark gap provides quick and easy timing circuit that allows the coil to produce many pulses a second rather than one single long pulse.

what is the range of this device ? would it work through a brick wall ?

if somebody could make this for me and send it to me, I would be eternally grateful, and it may even come with a cash reward ;)

all U need is a small obergine! India

I would like to build something like this, not to destroy anyone's belongings but to simply make a jammer for my car. I was involved in an accident by someone texting and driving, is there a way to make one without harming electronics and have a small radius? Pretty much to keep people off their phones while I'm next to them driving? Only if it's legal too. I haven't some much research on it.

You can, but it's illegal and easy to trace.

So, you can change the frequency of the spark gap on the bottom. That's cool and all, but what difference would it make to have a larger or smaller spark gap? Does that make it more or less powerful? It looks amazing and I want to build it, I just don't understand the point of being able to change the spark gap.

Hey kedar!! I think the wire you used was not 32 gauze. It was less.

What is the effective range of one of these things?

What should I do if I left the red wire touch the battery overnight (and now it won't work)?

UPDATE: The red wire works now.

What do I do if I left the red positive wire from the 1000 kV pulse generator touch the positive part of the battery overnight (it doesn't work now)?

I made one of my own . and it can jam a little alarm clock. 5 Stars for the instructions
