Have you always wanted a Faraday Cage to protect your sensitive electronics from an EMP, but were afraid of the cost? Well, consider this idea on making your own Faraday cage for about $5 each. And the best part: you can make several of these with the supplies you’ll need! Here’s how…
“Although the EMP literature is scarce, and often contradictory, I found a “recipe” for a Faraday cage that should withhold both types of EMPs, whether natural or man-made. Based on my own research, I’m pretty sure this will work better than a microwave, a galvanized trash can, or some of the other solutions you can find online.
The idea is simple: wrap your devices in alternating layers of insulating and conductive material, then put everything inside a thick ammo box.
Aluminum foil is cheap, you can find cardboard around the house for free, duct tape and packaging tape are also dirt-cheap, so you can make a cheap Faraday cage for less than $5. Now you will spend more than $5 for these supplies, but keep in mind you’ll be able to make several cages for this amount of money. This doesn’t include the ammo can, which you also probably have in your garage…”
“If you’ve been in the prepper world for long, you’ve probably read some horrifying books about what can happen after a disaster called an EMP. And if you’ve done that, you know you need to protect vulnerable electronics. Today, we’ll talk about how to make a Faraday cage to do just that. Don’t worry – you won’t need a degree in physics to do this successfully.
First, let’s start off with a few important things to know.
What is an EMP?
EMP is short for electromagnetic pulse. It is a short burst of electromagnetic radiation that could come if a nuclear detonation occurred at very high altitude above us.
When a nuclear explosion occurs in space above a target, three types of electromagnetic pulses follow: E1, E2, and E3. An E1 pulse involves high-energy gamma rays colliding with air molecules nearly 20 miles above, then raining down electrons that get pulled in by Earth’s natural magnetic field. An E2 pulse comes from high-energy neutrons that get fired in every direction, and an E3 pulse occurs due to the size of the nuclear fireball itself affecting the Earth’s magnetic field. As nuclear physicist Dr. Yousaf Butt explains, these pulses affect everything in line of sight of the nuclear blast. For example, a blast at 60 miles up can affect a 700-mile radius on Earth…”
