Hello my dear friends. An EMP is a popularly used sci-fi gadget in movies and you can make it from very common household items. So, today I am going to show you how to make an EMP gun.
EMP stands for electromagnetic pulse. EMP devices can damage any electronic device or disturb there functionality. Please be careful while making this EMP Gun. Also, be wary that use of an EMP is illegal in some areas. I am making this device for purely educational purposes - to know the effect of EMP on day to day consumer electronics. Please do not use for destructive purposes; I will not be responsible for damages.
See This EMP Gun in action in the video above!
Step 1: How It WorksThis EMP Gun works on the principle of electromagnetism. EMP devices use a high voltage generator that will convert 3.7 volt into a few thousand volts. Voltage is further amplified through passive voltage multipliers, then it is passed through an electromagnetic coil with the help of a spark gap. This coil will produce high frequency electromagnetic pulses. It is possible to increase the range of the power output; with the use of a capacitor connected to a coil, it will increase the power output of an emp. You can see in my demonstration video the stopwatch, RFID tag, memory cards - nothing survived.
The intense magnetic field created by the EMP gun affects the circuitry of other electronic devices, which basically affects the voltages all over the circuit. So, you will never know what will happen. Either the device memory will reset or it will permanently damage the device. So be careful. Keep your electronic devices far away!
Step 2: Things You Will NeedMaterials
- A bug zapper racket, usually used to kill mosquitoes. We will use its high voltage generator.
- You will need half a meter of 1 sq mm thick piece of insulated wire to make a coil. Alternately, if you want more range out of it, you can use enameled copper wire and coiled around as many times as you want.
Tools
- A soldering iron
- Soldering wire
- A bit of time and patience!
- Okay friends, start by taking apart your bug zapper racket using your screwdriver. Inside you will find a high voltage generator circuit. We are going to use this high voltage generator circuit along with the battery.
- Now take 1 sq mm wire. Make a coil as shown in the picture.
- In my design, I removed the output capacitor to limit the power output! But you can keep the capacitor as it is.
- Solder one output wire of coil to the high voltage generator and form a spark gap using other output wire as shown in the picture above. You may need to fix the wire at a distance. Keep in mind that this gap decides the frequency output of your EMP gun; the closer the wires are the higher the frequency will be and vice-versa, so you may need to tweak the distance. I found that 1 millimeter distance in-between them worked best for me.
- To make a handle for the EMP gun, I used my old toy gun. I removed the handle and stuck all the parts together with bit of a hot glue.
- I also extended the push button switch so I can use it as a real EMP gun!
Please do not point the gun at anything; it can cause real and permanent damage.
Instead, you can watch me testing this gun in the video. Be safe, act safely, and enjoy learning a lot!
