How to make EMP Jammer

EMP Jammer

In this article, you will see what is EMP jammer and how to make an EMP jammer.

What is EMP Jammer?

EMP is defined as Electro Magnetic Pulse. Emp jammer is a simple high peak pulse generator. We know current flowing through the conductor generates the magnetic field around the conductor. If we supply current with intervals it generates field pulses on the conductor, field increases suddenly and decreases. If we apply current pulses it generates high electromagnetic field pulses. These high-intensity pulses induce into devices and damages the device.

Make EMP Jammer

To make EMP jammer you require, a high voltage generator, coil, and switch. You can find the block diagram below.


In the block diagram, you can see a gap in one wire, it is called as the spark gap. As our need is to generate pulses this spark gap is used. When the high voltage is generated, it tries to jump from one terminal of spark gap to another terminal, which leads to generating EMP. The spark gap must be 2mm to 3mm. Let’s have a look at the following tutorial to make emp jammer with components available at home.

Components Required

emp jammer using mosquito zapper

  • Old bug zapper – 1
  • Old Adapter Case – 1
  • Switch -1
  • Hookup wire – 50cm.
  • Double Sided Tape

EMP Jammer Circuit

emp jammer circuit

1. Take out the circuit out of the mosquito zapper.

2. Make a coil of 3-4 turns of hookup wire.

3. Solder one wire of coil to the anyone terminal of the capacitor at the output.

4. Glue another wire of coil near the another terminal of the capacitor at a distance of 2 mm or less than it.This is to create a spark gap.

5. Solder wire to circuit activating the switch to extend the switch out of the case.

6. Place the circuit in the case carefully and turn on the circuit and close the case.

7. Apply glue on the case then fix the switch and solder activating switch extending the wire to it.

8. Now apply a piece double sided tape to the case and fix the battery.

Here the circuit construction completed.

Note: While using this device, keep your electronic devices away, it may damage your device. I will not be recommended to use it. I made this for educational purpose only.

Keep this device away from people who were installed with pacemaker, stunts.

Usage of this kind of devices is not allowed in some countries, make sure your countries policies before making this device.
