A Faraday cage is a sealed enclosure that has an electrically conductive outer layer and a non-conductive inner layer. The purpose of this box is to protect any electronics inside it in case of an EMP. I’ll also show you how to test your Faraday Cage (it’s easy).
Here are some Faraday Cages you can make at home in a couple of minutes:
Protect Your Computer From An EMP Using A Trash Can
20.5 x 20.5 x 27 inches (31 Gallon) – 6 times larger than the cardboard box
Line the trash can with cardboard (or carpet padding), including the bottom, making sure there are no gaps.
You can fit here a lot more electronics including an old laptop with your survival books and maybe a very small generator or a small solar panel.
