3 Ways to Build a Faraday Cage

JR from DIY Prepper shows that protecting your electronics from an EMP or solar flare doesn’t have to be expensive, using simple setups like a metal trash can, ammo can, or a foil-wrapped box to create effective Faraday protection. By sealing seams, adding insulation so devices don’t touch metal, and layering foil to block signals, these budget-friendly solutions can safeguard critical gear like radios, power stations, and solar equipment—giving you a reliable edge in a grid-down scenario.
