Do it yourself Faraday Cage

CopperKnight and I were talking a while ago about making a whole room into a Faraday Cage. Something to protect the electrical gadgets we all dearly love in the event of an EMP strike. I saw a great tutorial a while ago that turned an ammo can into a Faraday Box. Very easy to do--just line the whole thing with thick closed-cell foam, and then wrap your electronics in bubble wrap and place them inside.

WWYD? If you were to build one this weekend, what would you place inside?

I'm thinking of a solar-powered/crank-powered AM/FM/Shortwave radio. I have a mini Grundig I bought a few years ago that would be the perfect size to put in there. An 8GB thumbdrive with copies of important information and stuff that could be useful once the power is (hopefully) restored.

Maybe an older digital camera that I don't use anymore. Take the batteries out and keep them separate from the camera. Document things that happen after the EMP strike.

A good LED flashlight with batteries. (removed, just like the camera)

A Brunton solar-powered charging kit for hiking/backpacking. That way I could power up the rechargeable AA and AAA batteries for my devices.

Heck...I'd put my iPad in there but I use it almost every hour of every day.

Let me know what you'd put inside that you'd like to keep safe.
