In the event of a nuclear strike an EMP or Electromagnetic pulse is released frying all circuits near the area.  This inscrutable will teach you how to build a  Faraday cage. A  Faraday cage is a box that protects all electrical items placed in the box. I'm sure there are better ways to build a Faraday cage but this is a cheap version.

Step 1: What you need

- A metal box
-Duck tape
-Something that you want protected

So, wrap stuff in newspaper, put it in a steel box and tape it shut?

The idea of the newspaper is to keep your device from touching the steel. I wouldn't use paper though rubber definitely would work better, if you can't find that get something else nonconductive plastic sheeting, foam, etc

Yes, but lining the box with rubber would work better.

I guess this is better than "Get an EMP proof box and put your stuff in it". ;)

im not sure if they make those.

they do but there stupidly expensive way easier to just make your own.

They do, but this is certainly a lower cost option, especially if you have an old ammo can available.

I'll looking into building one to protect my stuff from the solar flare that may or may not be abosored into earths atmosphere

There will be a solar flare hitting earth, "ONE DAY" You'll probably be long dead by the time this happens or maybe not no way to know. But this has happen many times in the past just not many times since people have been on the earth I think the last time was in 1859, which disrupted and disabled the telegraph fortunately that's about as advanced as we were back in the day. Never hurts to prepare though.

Also,,What is the Duck/Duct tape for ,really ???

Making sure the box has a tight seal.

Ammo can's usually already have a seal. This one might be missing it's seal so the duck tape would make sence then.

does it have to be newspaper? or can it be regular paper?

It can be anything that keeps what ever your putting in the box from touching the metal it's self. I'd prefer to use styrofoam (the thin slabs of Styrofoam work best) Your lining it so nothing touches the medal.

Also keep any packets of silica gel that might come with any electronic/fabric goods you buy. They absorb moisture in a semi-sealed environment e.g. packaging, so that the goods (materials, circuits) don't spoil while in storage (oxidisation, mould). Then put the silica-gel packets in the metal box with the rest of the electricals/electronics, especially if you are bugging out in the open air and the box is in your backpack. Same should go for any kind of longterm storage in variable humid environment. I've never done this, but the silica gel can be dried out if water-saturated, by cooking them on a heat and be re-used. However I wouldn't know what the effect of the silica would be on stored devices during an EMP attack...but it does have some electromagnetic properties.

I would also consider wrapping the electronic/electrical goods in foil before storing them in the box, its inexpensive and just an extra layer of protection.

If your backpacking and your worried about ground, you could always run a grounding wire from your body and kit to a ground point on the soles of your footwear.

Just some ideas.

First let me say that __I could be Wrong. the way i remember it,is that govenrnents are spending a lot of money on research to build a EMP proof "box"....."".In the event of a nuclear strike an EMP or Electromagnetic pulse is released frying all circuits "".........and they have NOT yet come up with something that WILLwork.. maybe since(in the meantime) they have. if not,EMP type weopon might send us back to"DARK ages".
Actually, a Faraday cage is quite simple to make. It must simply be an interwoven cage of copper and steel, or perhaps brass. Mythbusters built one that was quite effective, blocking radios, cell phone signal, etc, out of a simple box of brass mesh. The only requirements are that the material be conductive, and that any holes be smaller than the wavelength of the desired radiation. It is also advisable that the cage be grounded and very thick, if full blockage of radiation is desired.

It should be grounded in order to dissipate the charge. also that can maybe too small for that radio. If the radio is too close to the wall of the can newspaper is not enough to prevent the charge from arcing on antenna or input jack.
