Build Your Own HERF Gun

James writes "Rostislav Persion from Voltage Labs has successfully constructed a HERF gun (a device like EMP but directional) in his home that is capable of stalling cars at a distance and crashing computers as well. He has videos of the device in action as it lights up LED's at a distance and triggers motion detectors. Theres also a bunch of other security stuff and science stuff which is quite interesting and controversial, such as cell phone tracking, mood altering audio signals, gyro guns, and other things of this nature. The site owner was also featured in US News Magazine and MTV for some of his work."

So, what would this do to an airplane? One that's, say, in the takeoff phase, heavily loaded with fuel and hundreds of passengers on board?

There'd be some protection from the fact that the airplanes are designed to withstand a lightning strike. A tube of aluminum thick enough to carry its own weight is a really good conductor, better than most electrical connectors. Windows and antennas are all that keep it from being a Faraday cage.

I would never forgive anybody who tried it outside a lab, though.

I never will get why people talking on cellphones in a restaraunt is annoying, but people talking just as loudly to people sitting next to them is not a problem.

Anyone else think Slashdotting is criminal?

[BobTheWonderMonkey]

/. has willingingly just exceeded this guy's bandwidth. He now owes his ISP money (and probably lots of it) because /. linked.

Now, does anyone else think that the Slashdot Effect is getting to be criminal? C'mon, people, we GAVE IT A NAME. It's not like we don't know what posting to /. is going to do to someone's servers.

Editors of Slashdot: you guys are getting criminally negligent. If no one has sued you so far, you better start getting the lawyers ready.

The EMP will fry the anti-lock brakes. ABS systems are designed to lock the wheels in case of system failure. (Ironic in a way...)

Bullshit. It would be totally stupid to design the system that way. If it fails while you were going down the road at 70MPH you'd have a very good chance of dying. I can't even imagine what would make you think it works this way.


From http://www.abs-education.org/faqs/faqindex.htm:

What if the ABS fails? Anti-lock brake systems are designed to be fail-safe. Nevertheless, they are equipped with a diagnostic feature that automatically activates and tests the major components each time the car is started and monitors them throughout the journey.

In the rare event of a failure, the ABS would be deactivated by its own safety circuit. A warning light goes on indicating to the driver that the vehicle is now in conventional base-brake mode.
