.:: EMP BOX ::.
EMP BOX. Disables Electronics at close range


PROJECT:

My goal is to build high power and optimal EMP box. After doing research I have found a total of 3 types of devices.

!!! DISCLAIMER !!!:

1) BE CAREFUL WHEN WORKING WITH HIGH VOLTAGE

2) DO NOT USE THIS DEVICE FOR VANDALISM

3) IT MAY BE ILLEGAL TO CARRY THIS DEVICE



There are 3 things that an EMP can do. It can reset a device, it can scramble it or it can completely fry the circuitry. Here is a video that shows resetting and scrambling. I was unable to permanently fry the calculator but it may be able to fry other types of devices.

TYPE 001: DIRECT POWER SUPPLY VERSION





PARTS:



The slow loud discharge between the terminals suggests that the power supply has a high internal capacitance. If the inner mechanism is a cascade then this capacitance won't resonate with the output coil.

1) 9kV DC power supply (claims to be 400kV)



2) Spark gap



3) 1 turn, 3 turn, 5 turn, 10 turn, 20 turn, 30 turn, 40 turn (26AWG 6cm diam)

4) Wire / alligator clips



5) Something to fry



TYPE 002: CAP ON POWER SUPPLY





PARTS:



The slow loud discharge between the terminals suggests that the power supply has a high internal capacitance. If the inner mechanism is a cascade then this capacitance won't resonate with the output coil.

5) Wire / alligator clips

TYPE 003: CAP NOT ON POWER SUPPLY

RESULTS >>>



Before reviewing the results, I would like to state some inaccuracies with my measurements...

1) When testing coil/LED it was difficult to tell when the LED turned off. Range might not be 100% accurate.

2) When connecting circuit, I used alligator clips. The length (inductance/resistance) of the wires may throw off results for coils that have low number of turns.

Here is a video showing the difference between resetting and scrambling...


Here is a video of me testing the range using a 10 turn coil (5.5cm diameter) to see at what distance I can light an LED...

I tried this experiment where I put two coils side by side. I pulsed energy into the primary coil and the LED on the secondary coil lights up. I thought that only polarized coils will work, however it works side by side for some reason...

P.S. ... I tried EMP type-003 with a 5 turn coil (6cm DIAM) using different capacitors: 470pF, 1800pF and 2200pF ... I got the same results for every capacitor.
