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…”
