Faraday Cage

[Grimmis]

Does anyone have a link or steps to building a suitcase sized faraday cage? I'm just looking for something to stash away in a garage.

Any metal container with no holes or cracks larger than a few millimeters is fine.

 

[Grimmis]

Guess I didn't think of the simplest way! Thanks.

Get a dead microwave of a suitable size. Those are Faraday cages.

Chicken wire with wire straight to ground. They aren't real complicated.

Wire should be pretty tight to stop the energy. In my opinion it should be smaller than chicken wire, less than 2mm x 2mm air gap.

Stainless or metal screen door wire would be easy to work with, readily available and simple to enclose something in.

Doesn't necessarily have to be grounded. Doesn't hurt I guess but isn't critical.

Heck an ammo can would work, microwave as mentioned, refrigerator, freezer, oven, old style metal bread box.

For added precaution you could put electronic devices in the metallic mylar bags or ESD Bags with a layer of non-conductive material between them and the outer metallic shell.

All pieces of metal used in the cage, including the lid or door, must be electrically bonded to each other.

Would a gun safe work?

Would a gun safe work?

probably. But not one with an electronic lock.
