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.

Seems like it would make a great replacement of the smokescreen spy-gadget in a car chase - just put a directed EMP device facing out the back-window and fry the electronics of any car chasing you too closely.
