I was listening to a Podcast last year. The Conversation was about the Sun and it going into Hibernation
and the effect it would have on the Earth over the next 50 years. The topic of a Carrington Event came up. The Guest, an Electronic Warfare Expert, said the number one question he was always asked, was how to build a Faraday Cage, this is what he suggested:
To make a Poor Mans Faraday Cage. You will need:
1 Metal Rubbish Bin. (They come in different sizes and are generally all Galvanised.)
2 A roll of this- https://www.screwfix.com/p/aluminium-fo ... -45m/50629
Take your bin and draw a marker line around the rim of the lid, onto the bin itself. Then remove the lid. Then with the tape, tape over the line, making sure the tape is equal on both sides of the line. This is to make that the Lid, fits tightly onto the bin. Also when you come to seal the bin it will bind with the pre placed tape. Also put some onto the lid as well for the same reason
You should then place the Roll of Tape into the Bin until it's needed. So you know where it is at all times.
In the event of an EMP, which I might add is more likely to come from the Sun, and which we would get about 12Hrs warning notice!
Place your valuables in the bin, then take the Foil tape and tape the lid around its rim, to the bin. Sealing it tight.
That's is your Poor mans Faraday Cage.
Now you should be able to do that, depending on the size of bin, for about £30 or less. Especially if you are just looking at putting phones and IPads into a small size bin. You could if you want, line the bin with rubber mats if you so which to. Just to give your valuables some extra protection.
