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.

While you’re not likely to actually damage anything in a dramatic way with this little EMP, it can still interrupt an important memory write or radio signal and damage it that way. It’s a great way to get the absolute shock of your life if you’re not careful. Either from the HVDC converter or the FCC fines. Video after the break.

TP-LINK’s WiFi Defaults To Worst Unique Passwords Ever

This “security” is so outrageous we had to look for hidden cameras to make sure we’re not being pranked. We don’t want to ruin the face-palming realization for you, so before clicking past the break look closely at the image above and see if you can spot the exploit. It’s plain as day but might take a second to dawn on you.

The exploit was published on [Mark C.’s] Twitter feed after waiting a couple of weeks to hear back from TP-LINK about the discovery. They didn’t respond so he went public with the info.
