Faraday cages for protecting sensitive electronics. An old microwave oven with the guts removed can be used and the cabinet used for storage. They are designed to keep microwaves in but it also keeps stray EMP’s out. If you do not have time wrap the electronics in aluminum foil.

Awesome idea!

Does anyone have any idea how much warning we will get in the event of a massive solar flare?

You'll have about 2 days if you sign up to something like spaceweather. Maybe 24 hrs by mainstream news.

I like using old ammo boxes, found at most surplus stores. just make sure you line them with a non-conductive material (corrugated cardboard is great). I have a few, 20mm ammo boxes that work great. But need some more to make a heater/oven. :mrgreen:

Ranger2012 the ammo boxes wont work for emps. they have a rubber seal around the under side of the lid that helps keep moisture out but will let an emp affect anything inside. the best and cheapest thing to use is a tin or steel garbage can, the are big and you can put alot in them. the point of a faraday cage is to allow the emp to go around what ever you are protecting so you need something that conducts electricty, like electricty an emp will follow the path of least resistance so it will travel around the can and continue on. even if what ever you are protecting is touching the can it will not affect it. If you have a brak in the faraday cage the emp wont travel arount it, it will go through it and everything you have inside will be hit.

If you want to try it get a pice of aluminium foil and your cell phone, call your cell phone with your home phone and as it is ringing wrap it with the foil as soon as you close the foil and make a complete un broken wrap around the phone it will stop ringing and you will not be able to call it untill you un wrap it.

dude that is funny stuff! ok so you put the tape on the seal but it is not a conection because the glue could act as a insolater, as rediculis as it sounds. 15 bucks for a garbage can at home depot and your good for sure, just saying. I use the ammo boxes to store my knifes and fishing line as well as first aid stuff. I will try to cover faraday cages in my B.O.V. videos im going to put on youtube for you guys as i am going to make the truck emp proof.

Cool....are you going to use "laymans terms" so that those of us not "mechanically minded" will understand how you've done it?

Just acquired, at very low cost, a peanut tin. I will be placing USB drives and possibly a small computer in it after insulating, and sealing it using solder. It's rectangular, about 6.5"x8.6"x2.5" and will serve as my data protection tin. I'll be picking more of these up, as they are very stackable, and cheap. Thought I would throw that out there 🙂
