JR from DIY Prepper breaks down three simple, low-cost ways to protect your electronics from an EMP or solar flare. Using common materials β a metal trash can, ammo can, or foil-wrapped box β he shows how to seal seams, add insulation, and block AM/FM and cell signals effectively. Each setup is tested and budget-friendly, costing $40β$70. Perfect for safeguarding power stations, radios, and solar gear in a grid-down event.
Key takeaways
Metal trash can + foil gasket = best large setup
Ammo can = great portable option for radios & flashlights
Cardboard box + multiple foil layers = ideal for panels or generators
Always insulate inside so items donβt touch metal
Use 3β5 foil layers to fully block signals
