What Do You Put In Your Faraday Cage?

Post by thecrownsown » Mon May 14, 2018 1:54 pm

I'm wondering what equipment you put in your faraday cage? Sure, I've put in an emergency wind up radio and wind up flashlights. But what else do you put in them?

Is putting an old smart phone loaded with books/manuals a good idea? or tablet? Or is it wishful thinking with limited battery life? Do you need to put batteries in a faraday cage or will they weather an emp?

What are some of the most import things to put in one? What are some things I should be adding? I have that true and tried "metal garbage can" model. So space is limited, but willing to build bigger if necessity requires.

I find this topic very confusing. It seems that there are multiple positions taken: the Faraday cage is the answer; to EMP is such a remote possibility that the threat doesn't need to be addressed; to just turn off your equipment and have a circuit breaker; to unless you're targeted specifically (military installation) don't worry about it.

Several things I've read have mentioned that short wired electronics are at low risk (unplugged computers) and that Cell phones have even less to worry about. Again much information/misinformation is available. In a nutshell, I haven't been able to establish that this is enough of a sustainable threat for it to take preference over other preparations (time, storage space, investment) that it warrants procurement.

Obviously you do, so I'll ask you for your opinion. Any guidance is appreciated. What is the real risk?
None you improvise, one (or more) is luxury.

Question for those with more experience on the topic...

I have a large metallic fireproof gun vault. I’ve been keeping some back up electronics in there, mostly out of convenient sto rage, but also because it has dehumidifiers that keeps things climate controlled. Would this setup work for an EMP? I’ve tried the whole cellphone in it and see if it rings, but living in the country side, I’m already lucky if I get reception standing by the kitchen window... so putting a cell in a metal box in the basement pretty much invalidates any tests I can do.

As for storing, I have an emergency multi band radio, my FRS radios and a few Baofeng radios. I also have a solar battery charger.

I have absolutely nothing in a faraday cage...at this time.
This is due to research that appears to oppose the common belief that "everything" will be fried combined with my belief in the likelyhood of an emp attack.
That being said, it would appear that solar panels that are NOT connected would survive an emp. Some sources claim no effect at all while others claim no more than a 5% reduction in performance. Either way, I am going to trust that disconnected solar panels will be OK.
I would also point out that all though emp is low on my priority list, it IS still on the list. I'm starting to look at emp bags for a few items that would include:
1 - solar charge controller
2 - a couple baofeng radios
3 - a backup HF ham radio
4 - a tablet loaded with whatever I have not had the chance to print out
5 - various usb keys with personal info and documents as well as various other information
6 - a small laptop that I mostly use for ham radio stuff, but is capable of other applications

This is by no means a finalized list...I may add other items as I think of them.
If you follow the 2 is 1 and 1 is none rule, then you probably already have backup items that could be put in a faraday cage, or at least be looking at getting them. In the end, the investment in a faraday cage seems reasonable, so what could it hurt?

My limited experience:
-My cell phone will not accept calls, but will accept data in a metal "garbage can" style farady cage.
-My cell phone will not accept calls, or data and is pretty much intert when I keep it in my gun locker. The locker is thick metal, and insulated with carpet on the inside....

-I was making a small EMP machine...but have just collected some of the components. The fact it is literally a tazer before you modify it into something that will provide a significant EMP is....problematic. Will keep ya posted.

I have a small fireproof safe which I am pretty sure will act as a faraday cage (I've kinda tested it) - in it I have backup USB sticks with critical docs, my baofeng UV5R, my solar charger for USB and a solar lantern. They do not take up much space, and lots of room for my other paper documents, passport, etc. Even if it does not work as a faraday cage it will protect against fire ;)

I have nothing in a faraday cage, nothing. No plans to get one. I have added protection to my inverter and panels but not because I fear emp or solar flares rather lightening, so I hardened them as they would be the most likely to fail with the greatest consequences do to such a strike. Back in roughly 2000-2005 I must have lost 4 dialup modem boards due to lightening. After about 2006 They started building the boards better and I never lost one after that.

Research Starfish Prime. In July 1962, the U.S. conducted high altitude nuclear tests. The resulting EMP caused catastrophic failure to several satellites. The major portion of the damage was to the solar panels on the satellites.

yes...but the point to remember is that those solar panels were connected and being used at the time. I was refering to unconnected panels.

A metal gun case is said to work as a faraday cage as long as the metal is tight fitting where the door is or the RF energy radio waves will go through the cracks and damage the electronics. Double metal layer improves chances of them working and having a insulation layer between the metal and the electronics such as rubber is needed. People sometimes wrap the electronics in tin foil for the extra protection in the faraday cage.

Doesn’t have to be a man made emp as strong solar flares are said to cause a emp burst.

Might be a time when I make a faraday cage but at this time I put my energy towards learning useful skills as technology can be to unreliable with or without a emp occuring.
