Hell Troll: How to build a mini-EMP generator to disrupt electronic gadgets

Have you ever got mad at the blaring music from your neighbours at 3.00 am in the night? It is one of those neighbours who don’t ever listen to anybody and play full pitched music in the middle of the night. Do you think it is time to teach such neighbours an unforgettable lesson? For such occasions and more, EMP is your best friend.

What is EMP?

If you watched movies like Matrix, you will know that Neo and his gang used EMP to stave off intelligent machines. This is the same EMP you will be using to put a stop to your obnoxious neighbour. An electromagnetic pulse (EMP), also sometimes called a transient electromagnetic disturbance, is a short burst of electromagnetic energy. Such a pulse’s origination may be a natural occurrence or man-made and can occur as a radiated, electric or magnetic field or a conducted electric current, depending on the source.

The electromagnetic pulse generator, or EMP generator, is a device capable of generating a transient electromagnetic disturbance that radiates outward from its epicenter, disrupting electronic devices (or frying, depending on its capacity). Some EMP bursts are naturally occurring, such as electrostatic discharge (ESD), where others, such as the nuclear electromagnetic pulse (NEMP), are man-made.

How to make your own EMP Generator

To make your own EMP generator you will need the following :

  1. Soldering iron
  2. solder
  3. disposable camera
  4. voltmeter
  5. small toggle button
  6. insulated thick copper cable
  7. enamel-coated wire,
  8. a high-current momentary switch.
  9. rubber gloves
  10. and other electronic/electrical accessories

Once you have got all the materials ready, follow this step by step guide to make your own EMP device.

Disclaimer : Playing with EMPs is dangerous and you may ruin your electronic equipment including medical gadgets and computers. This tutorial is only for educational purpose and Techworm is not responsible if you dont put together this experiment in lab conditions. Using EMP may also be illegal in some countries and we dont condone such actions.

If you agree to above terms, let’s get on with building your own EMP device.

Step 1: Obtain a disposable point-and-shoot camera
Purchase a cheap disposable camera such as the Kodak variety sold at the local drug store.

Step 2: Put on a pair of rubber gloves and open up

Put your rubber gloves to avoid the possibility of receiving a painful shock when opening up the camera; it’s flash capacitor carries 330 volts or so, when fully charged.

Step 3: Open the frame and locate the large electrolytic capacitor
Using the flat end of a screwdriver,carefully pry the camera’s chassis so that it cannot damage the printed circuit board beneath. Once open, locate the large electrolytic capacitor — the black cylindrical looking component with two leads — and the PCB to which it’s attached. Bear in mind that the side of the capacitor with the markings represents the negative terminal.

Step 4: Test the flash capacitor’s charge
Grab a voltmeter, set it to the 1000-volt scale, and verify that the capacitor is discharged. If voltmeter cannot find a reading, the capacitor’s discharged and you can skip step 5.

Step 5: Discharge the flash
To discharge the capacitor we’ll first need to activate the flash by inserting batteries and film into the camera and turning on the flash. Next, we press the shoot button and immediately remove the batteries to prevent the capacitor from charging again. Use the voltmeter once again to ensure full discharge. If a residual charge persists, place a 100-ohm resistor across the leads to ensure that the flash is fully discharged.

Step 6: Remove the PCB and replace its charge switch
Remove the capacitor’s PCB and find the on/off button. Peel this off and solder a push button in its place on top of the solder pads to reduce the risk of electric shock.

Step 7: Solder the capacitor

Solder two insulated copper cables onto the capacitor’s two terminals and wire one end to a high current momentary switch as shown below. The high current momentary switch can easily be procured from the Internet. Leave the other end unattached for now.

Step 8: Form the load coil

Wrap the enamel-coated wire 7 to 15 turns around a circular object with a diameter of 2 inches. Ensure the wire lines up precisely with no crease or overlap. Place double-sided tape around the diameter of the circular object to help with this.

Once you’ve created a satisfactorily thick loop, remove the object. Now bind the coil with adhesive tape but leave two protruding leads to connect the terminals. If you have an iron rod handy, you may slip it through the center of the coil to intensify the generated magnetic field.

Step 9: Connect coil and the switch
Use sandpaper to remove the enamel coating of the tips of the two wire leads protruding from the coil before attaching one to the other terminal of the capacitor. Next, attach the remaining lead to the ”on” side of the switch.

The end result will be a PCB with a switch to turn the charger circuit on and off along with a load coil that’s switched across the capacitor.

Step 10: Charge the EMP generator and fire
Simply re-insert the battery into the camera’s PCB to provide a power supply. When you’re ready to test out your creation, fetch the handheld electronic device you’d like to disrupt and flip the on switch. Do not simultaneously hold down the charge button while firing the pulse or you may damage the circuit.
