Faraday cage contruction?

Post by Flying Lead » Sun Dec 03, 2017 10:47 pm

Is it possible to build for a reasonable amount, a Faraday cage to shield something small like a generator or ATV?
Would it stop the damage from an EMP? Will a ship type container work?

I'm not an expert, but if you can seal the gaps in the doorway with metal and still e able to open it up and close. It should work. If your welding skills are up to the task you could weld up a small garage type container out of corrugated metal pannels.

do you plan on using it regularly?
does the ATV have an ECU?

My first though would be a shipping container with aluminium tape over the hinges, a wire mesh would work, but you'd have to ensure that the gaps are less than the wavelength.

A normal garden shed should work...but I do not know if the concrete would block electromagnetic radiation. It stops other radiation though

I hear a bag of chips will get it done.

Here's the problem with EMP prepping: no one knows anything.
The "experts" say a lot of different things. Some say a solid steel box is the only option, some say plug everything into grounded surge protectors and you'll be fine. But are they talking about an atmospheric nuclear EMP or a solar flare EMP? They almost never specify. I recommend taking all your research and taking liberal approach to the best practices that make the most sense.

All I can say is, before building big, practice small. Build some small strong boxes, cell phone/ham radio sized, and test them.
I picture Faraday cages much like water proofing caches: store everything in its own container as though it were being exposed to the elements on its own, then put those small containers into a bigger one that is equally protected from the elements. In this case your element isn't moisture and dirt but electrical energy in wave length formation.

Also, aluminum tape is a great recommendation, but you have to find the electonic circuit specific stuff with conductive adhesive, or to won't be effective

Dont forget to ground everything. I dont think a cold water pipe is good enough.

Every frequency has a different wave length. So if using conductor mesh you would need different layers of different sizes. Not like the one in Enrmy of the State. Box within a box etc...
