EMP Testing Video and Faraday Cages

The video speaks for itself, but I’d like to add a little to it – for the thick-skulled among us.

A “Faraday Cage” works by redirecting a current around whatever is put inside it. The mesh commonly used does this nicely. The electrical current flows around the cage on it outer surface. What gets me charged up is how so many people assume that a mesh cage will protect its contents from an EMP.

It won’t.

The energy produced by an EMP, and the currents we see in Faraday cage operation, are two very different things. So much so that you really only need to consider one simple question when looking at an EMP protection device: Are there gaps in the thing?

Gaps allow RF energy to pass. The broad spectrum in an EMP contains some very short wave lengths. Small holes, and even slits, can allow penetration. In fact, according to Sharon Packer, nuclear engineer and part owner of Utah Shelter Systems, gaps in a protective device may function as “slot antennas.” These allow for propagation of the RF energy into the interior of the “cage.” Not what we want.

So, will a mesh structure protect your equipment? Will a metal storage locker do the job? How about the trunk of your car? Don’t bet on any of them. My favorite is a completely sealed metal box with no path to the interior, not matter how small. Solder an ammo box shut. That’ll do it. Just make sure your container is accepting no energetic visitors.


In this video, Dr. Bradley of DisasterPreparer fame, conducts tests to determine what kind of a seal works best to join a trash can and its lid. He uses a nifty setup to measure energy directed at the can, and energy receive within the can. Through various methods of sealing, you eventually get to the point where you decide, “Yes. A complete seal is best.” Notice that he hints at slot antenna effect created by a gap as small as the film of glue on tape.

BOV Engine Damage - Options?

Once upon a time, (8 years ago…) I bought an F-150 work truck that went off lease. I tried unsuccessfully to kill it for the previous 3 years, and decided it wanted to stay with our household. With 121K on it, I thought it might be time for some spark plugs. In went the Autolites, and we were in business.

2 days ago, coming home from an outing, my wife and I heard a loud *POP* and a ticking –

What's Old is New Again

Barrage Balloons ready to rip the wings off low flying fighters and bombers…

An invasion force seeking to kill, destroy and conquer…

Evil intent seeking to work its will upon any and all…

You might remember the balloons from D-Day invasion pictures. They were restrained from flying aloft by steel cables. Any plane seeking to dive onto targets might lose a wing to the Ginsu cable as it roars past. It was a tactic used for a few decades in

Last Week's Chinese Hack of Federal Employee Info

The bold and successful hack of our Federal Employee database is a BIG DEAL. I’m sure you’ve heard that this information can be used for:

phishing schemes identity theft credit attacks e-mail hacks blackmail collection of further, more important and damaging information

In order to fully comprehend the importance of this effort, we have to look at what was done, and what can happen as a result.

Personal information regarding current and past employee identities was stolen. This information give

EMP Hardening Your Vehicle

The jury is out, and will never come in, on the argument about EMP damage to vehicle electronics. But I don’t need a jury. I only need what I know.

EMP can kill your vehicle engine and transmission control electronics. Yup. Kill it dead for sure!

….or not.

The vulnerability of ECMs and TCMs and MAPs and MAFs and CPSs and ICPs (and all the computers and sensors) to the over-current pulse many fear depends on a few things.

You Find 'em Where You Find 'em

I was in an electronics store this week, looking for a case for a PC build. This particular store doesn’t carry cases anymore, so I spent a few minutes looking at power supplies and assorted parts. There was a young lady in there, to my left, intently going over the offerings of a certain company. At one point, she moved a bit closer and we took up conversation. It turned out she is a product rep for a line of

New Blog by a Friend of Mine - Prep For Free

You might notice a new banner to the right of the page. It is a link to Prep For Free, which is a new blog written by my friend Nancy Argyle. She has a personal approach to building the fabric of a prepper’s material existence – the “preps.” Her title pretty much sums up her blog’s focus, prepping for free. I’m following her, and I think anyone could benefit from what she has to share.

Is the Economy Imploding? Zero Hedge

2008 was the apex of our last boom economy, where the financial and private sectors, including personal wealth building by individuals, created record wealth through myriad leverage schemes. A lot of this was invisible to giddy investors in the market and housing industries. When that bubble began to leak air at a dizzying rate, the truth was still lost on people. (No wonder they fell for the “Stimulus” B.S..)

Since then, the worry warts have multiplied like rats. I generally

Police Tech can be Perp Tech

When I see news about “official” law enforcement or agency incorporation of spy tech into their routines, I get a bit uneasy. Not because I have “anything to hide”, but because I have “everything to hide.”

“Huh? What do you mean?”

Here’s what I mean. If I have property that I’d rather not show the world, it’s MY RIGHT to keep it to myself – from everyone. I owe no one any knowledge of my life behind my walls. I
