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.

Very narrow frequency range. Very low power. Some 90s' kids toys had similar designs for sending morse code back and forth.
Look up the mil spec standards for EM protected electronics and find the civilian-to-military ranges. Reach that much and it's an EMP. Bellow that, it's a jammer.
You don't even have to go nuclear. A big enough inductor\capacitor or just using an explosive will do. I'm sure there are designs floating around for these sort of things.
The thing is, if you have explosives or the electro know how, what's the point? There's so many worse things you can do other then a silly EMP...
compiling...

What did you expect? It's set of DIY instruction found on Youtube ferchrissake... I made a more interesting "EMP generator" out of a doorbell and a car ignition coil when I was a teenager decades ago.
