A Faraday cage is a metal enclosure that shields electronic devices from electromagnetic interference, including EMPs. During am EMP attack, the explosion would render most electronics unusable unless they have been hardened or otherwise protected in something like a Faraday cage.
Faraday cages are pretty easy to make, you don’t need to purchase a built one, and it only takes a few supplies you can pick up from the hardware store.
Here’s how to make a simple, small Faraday cage for storing small electronic devices:
- A small metal container, such as a metal ammo can or metal trash can with a tight-fitting lid
- Aluminum foil or copper mesh
- Electrical tape
- Line the inside of the metal container with aluminum foil or copper mesh. Make sure that the material completely covers the inside of the container and that there are no gaps or holes.
- Place your small electronic devices inside the container. Make sure that the devices do not touch the walls of the container.
- Close the lid tightly and seal the edges with electrical tape to ensure that the container is completely sealed.
That’s it! Your small Faraday cage is now ready to store your small electronic devices.
Remember, it’s important to test your Faraday cage before using it to ensure that it provides adequate protection. You can test the effectiveness of your Faraday cage by placing a working cell phone or radio inside the cage and attempting to make a call or listen to a radio station. If the device does not work while inside the cage, the cage is likely providing adequate protection.
