Become Very Unpopular Very Fast with this DIY EMP Generator

Taking a break from his book, "How to Gain Enemies and Encourage Hostility," [FPS Weapons] shows us how to build our own handheld EMP generator which can be used to generate immediate dislike from anyone working on something electronic at the hackerspace.

The device is pretty simple. A DC source, in this case an 18650 lithium battery cell, sends power to an "Ultra High Voltage 1000kV Ignition Coil" (as the eBay listing calls it), when a button is pressed. A spark gap is used to dump a large amount of magic pixies into the coil all at once, which generates a strong enough magnetic pulse to induce an unexpected voltage inside of a piece of digital electronics. This usually manages to fire a reset pin or something equivalent, disrupting the device's normal operation.

Fun project in the spirit of TV-B-Gone.

[Ed note: This may or may not be legal in your area. It is definitely not recommended for use when a passenger on a moving vehicle.]

    How do I build this so it has more range? This EMP needs to be held RIGHT NEXT to what you're trying to pulse... This emp device is for whimps... I want something that can pulse shit in *at least* a 3 yard radius. THAT is how you make enemies...

    Inverse square law is a bitch,
    Probably not going to be pocket size if you need that much power

      How about mechanical flux compression? Not good enough for "civilian" purposes?
