Faraday Cages-Make Your Own

A couple of times, I have seen suggestions to make small faraday cages from popcorn tins!

You can also make one from a metal popcorn tin (the kind that might be a leftover from a Superbowl party). The object of a tight fitting lid is to create electrical contact in multiple places around the rim. You should lightly sand the contact surfaces of both the container and the lid to remove any plastic clear coat or paint.

The inside of the container has to have a layer of non conductive insulation that creates an air gap between the items you put into the container and the inside walls of the container. You might even put your items inside plastic bags to add additional protection against conductivity. You'll know that you have it correct when a radio or cell phone signal can't penetrate the container.

I have one of my friends saying he was using popcorn tins to keep his radios in. I decided to try a little experiment, I put my cell phone in a tin and called it with my home phone. It rang. I don't know if that's a valid way of checking for EMP security but if it lets RF in I think it would allow an EMP pulse. I told my wife about my experiment and later her and my daughter wrapped a cell phone in foil and THEN put it in the tin and it worked.... there was no ringie dingie. So maybe muliple layers will work.

How to Build a Simple Faraday Cage for EMP Survival
http://www.backdoorsurvival.com/how-to-build-a-simple-faraday-cage-for-emp-survival/

Of all of the reasons to prepare, one that we all need to take seriously is the possibility of a catastrophic EMP, or electromagnetic pulse. This is a frequent topic in many post-apocalyptic novels and something that most of us are aware of, even if we do not completely understand the science.

(Snip)

Understanding the risks of an EMP goes hand in hand with threats of a cyber-attack since there is a cause and effect relationship between the two. In this article I want to accomplish a few things:

Explain EMPs and the risks in simple, easy-to-understand language
Give you instructions to build a simple Faraday cage to protect your electronics
Provide a list of items to put inside your Faraday cage

Building Your Own Faraday Cage

A Faraday cage is an enclosed space with an outer layer that conducts electricity. The physical shape of the Faraday cage does not matter: it can be spherical, cylindrical, or a box. Either the cage itself can be made of a conductive material, or the cage can be built of a non-conductive material such as wood and then covered in a conductive material.

The conductive material can be as simple as several layers of aluminum foil, which makes constructing your own Faraday cage a fairly simple and inexpensive affair.   ---CONTINUED---

10 Faraday Cages You Can Make at Home
http://www.askaprepper.com/10-faraday-cages-you-can-make-at-home/

  After the nuclear EMP was discovered in 1962 (US Starfish Prime Experiment) people have been searching for all kind of methods of protection (against electromagnetic pulses).

One of the solutions we came up with is storing important electronics in Faraday cages.

I have recently spent more time on EMP research and testing and have come to several conclusions. The way I am now testing my Faraday cages is by placing a cell phone inside and seeing if it will ring. This has lead to some interesting results. The first thing I found was that the use of a microwave oven for a Faraday cage is very questionable. They will not block a cell phone transmission.

  (SNIP) there is a constant threat that could take these devices away from us. It is an unseen enemy that will overload our power grid and fry electronic devices without warning.

I’m talking about an Electromagnetic Pulse (EMP) or a Coronal Mass Ejection (CME). While EMP’s are generally going to be the work of unfriendly governments, a CME comes from the Sun, and there is nothing that we can do to stop it.

(BIG Snip) ... There are many ways to build a cheap but effective Faraday cage using materials easily obtained through online retailers or local home improvement stores.

There is, however, a simple but effective Faraday cage that you can build with materials that you undoubtedly have laying around your home right now.   ---CONTINUED---

  (HUGE SNIP) ... This may be the simplest way to quickly and effectively construct a Faraday cage . What’s good about a metal bucket aside from its Faraday characteristics is that it’s inexpensive, portable and easy to put together. It’s also large enough to hold and protect many of the electronic devices that can be harmed by any electronic intrusions from EMP’s to hackers. Here’s what you need to do ...   ---CONTINUED---
