10 Faraday Cages You Can Make at Home

After the nuclear EMP was discovered in 1962 (US Starfish Prime Experiment) people have been searching for all kind of methods of protection (against electromagnetic pulses).

One of the solutions we came up with is storing important electronics in Faraday cages.

If you are not familiar with the destruction effects of an EMP, you should probably watch this short documentary and learn what the biggest threat to modern-day America is, and what you can do today to keep your family safe.

The Army is also preparing for this. Recently, NORAD has moved its communication equipment back to its nuclear Cold War-era bunker under the Cheyenne Mountain because this base is EMP hardened.

The government is also making small steps to harden the grid. Maine has become the first state in the nation to pass legislation ordering its grid to be hardened against an electromagnetic pulse. (Source)

Even the Police have some new small Faraday bags for confiscated cell phones – to preserve information.

Back in 2004, The Congressional Study EMP Report indicated potential casualty rates of 90%. Don’t expect Uncle Sam to protect you. We all have to be prepared.

To avoid a total collapse every American should have some EMP hardened equipment or at least a Faraday Cage to protect the most important survival electronics. (a radio, a small generator, electronic parts for cars, etc … Read more: Things to have ready before the EMP)

A Faraday cage is a sealed enclosure that has an electrically conductive outer layer and a non-conductive inner layer. The purpose of this box is to protect any electronics inside it in case of an EMP. I’ll also show you how to test your Faraday Cage (it’s easy).

Here are some Faraday Cages you can make at home in a couple of minutes:

1. From a Pasta – Fettuccine in this case – Box

8.5 inches high, 7.3 inches width and 3.3 inches deep

You can store in this box a small radio, a solar battery charger and some electronic parts (duplicates) for your car (like the PCM – Powertrain Control Module, the Anti-lock Braking System, the Electronic Fuel Injection, the Electronic Ignition, etc)

Wrap the box in heavy duty aluminum foil (at least two layers). When you do so… be careful to isolate it completely.

Faraday box aluminum pasta

The Test: As you can see, I left a phone in it to test my Faraday cage. If you don’t wrap it completely in aluminum foil you’ll be able to call yourself from another phone. In this case, the box was perfect and I couldn’t call my phone because there was no signal in it. Anyway, the phone test is 99% accurate, because the phone signals are a bit higher in frequency than an EMP. If you want to be 100% sure that you made an EMP hardened Faraday cage then you should place a small turned on radio. If it stops… then you have an EMP hardened box.

Tip: if you can call your phone, then wrap the box in another layer of aluminum foil and try again.

2. From an Ammo Can

ammo can Faraday cage11 x 5.5 x 6.75 inches (volume – two times larger than the pasta box, but because you’ll lose some space with the inner non-conductive layer… the volume will be quite similar to the previous one – pasta box)

“This 50 Cal ammo can from an army surplus store and some scrap foam for padding and insulation make an inexpensive, easy to carry means of protecting essential electronics gear.” Source

3. From a Cardboard Box (from IKEA in this case)

8 inches high, 11 inches width and 13.3 inches deep (triple the volume of the Ammo can and 6 times larger than the pasta box)

Faraday Cage with Aluminum

The principle is the same (as Pasta box)… just that this one is larger and can be opened every time you want without tearing up the foil.

4. A Bird Cage

chiquita-dometop_bird_cage_lVolume: Variable – depending on the cages.

There are two problems with these cages:

  • some have the bottom made of plastic (without any metal outer layer)
  • and some have too large holes to protect against high frequencies

But chances are that you have a normal bird cage, which will work as a Faraday cage if you place some foam (for example) in it.

If it does not work, it probably means that the holes are too big so you’ll have to wrap the cage in aluminium.

5. From a Trash Can

20.5 x 20.5 x 27 inches (31 Gallon) – 6 times larger than the cardboard box

Trash can Faraday Cage

Line the trash can with cardboard (or carpet padding), including the bottom, making sure there are no gaps.

You can fit here a lot more electronics including an old laptop with your survival books and maybe a very small generator or a small solar panel.

6. An Old Wooden Ammo Box Wrapped in Aluminum Foil

Volume: Variable – depending on the boxes.

Woon Ammo Box Faraday Cage

Similar to the cardboard box, but you have to pay attention to the nails.

You don’t want the nails (which the box already has) to connect the aluminum foil with the inside of the box.

7.  A Metal Storage Cabinet

metal CabinetThis Faraday cage provides greater storage capacity and extreme protection. It has a lot more space. I know someone who stores in it a small dorm size refrigerator.

Remember that everything you store in this Faraday cage has to be in a non-conductive box.

8. With Wood and Aluminum Screen

Volume – variable – depending on how big you want to make it.

There are many “walk in Faraday cages”… so if you want to build a huge one to store even a large generator or some solar panels, this is the method you should use.

Faraday cage steps aluminum

Make a wooden frame and attach a wooden (frame) lid (using 1-2 hinges). Attach the screen mesh. Remember to isolate the bottom of the box (with wood, cardboard or plastic) and to keep away the electronics inside from the Aluminum Screen.

Tip: Instead of nailing the wood, try to glue it.

9. Using Cookie or Popcorn Tins

FaradayVolume: variable – depending on the tins.

The lids on these tins are typically very tight, which make them ideal Faraday cages.

Just line the inside with cardboard (including the lid) and put in the electronics you wish to protect from EMP’s.

If you find it too hard to line the inside of the box, then try this: put your phone (for the test) in an anti-static drive bag (plastic) and then put it in the tin.

10. Keeping the Generators/Tools/Radios/Electronics in Their Original Boxes

Volume: Variable – depending on the boxes.

Faraday cage in boxes

This is the easiest way! Here is a video guide for this method. If you don’t use on a daily basis what you want to protect… just keep it in its original box and wrap it with heavy duty aluminum foil.

Some people may say that it’s crazy to prepare for an EMP. Well… I think that a solar storm is a real possibility. A terrorist EMP attack is also a real possibility. A nuclear war is also a real possibility. The probability: maybe 5% per year. But 5% is not crazy. Not even 1%. If your doctor says you have a 5% chance of dying … wouldn’t it be crazy not to do something about it?

Well… given the fact that it takes only 10 minutes (max. one hour) to build a Faraday cage, I consider this a well “invested” time.

On a national scale: It would be wise to follow Switzerland’s lead. According to Radasky, that country during the cold war hardened some of its critical infrastructure against EMPs, such as water works. “They felt that if there was high-altitude burst over Europe, they were going to be affected whether they were a combatant or not.”

    Using a cell phone to test your Faraday cage is a poor test, as it’s very easy to block those high frequencies. Many people are being falsely led to believe they have an EMP Faraday cage by these tests. A better test is to use an AM radio, particularly when you’re standing next to a 50 kW transmitter.

        2. What’s the simplest method to sleep without the body being bombarded with wifi?

        3. Will a grounding sheet in the bed help dissipate the microwaves destined for the body?

        4. If I have aluminum Venetian blinds over the windows, and ground them, could that help minimize wifi penetration from outside?

        5. If a add carbon graphite powder to wall paint, and ground the walls, could that help minimize wifi penetration from outside?

        6. I read that if you have a cactus pot plant nearby electric devices, that it helps absorb dirty electricity instead of it entering the body. Do you agree, and if so how would you test that a cactus absorbs emf+rf?

        7. I read that a Himalayan salt rock lamp, when warm, emits negative ions into the vicinity and thus will attract positive ions from emf/rf. Have you heard of this actually working?

          You’re wasting your time. You are being bombarded with EMR 24/7/365 for your entire life. Your neighbor’s low power wifi is the least of your exposure issues. The bottom line is that to do what you want, you would have to make a Faraday cage around yourself, large or small, just scale up the instructions here and you don’t need the insulation on the inside of it either, but as soon as you step out of it you are right back to being bombarded with thousands of RF transmissions again, none of which have been proven harmful in any way, so what’s the point unless you are going to live in the cage 24/7/365?

            Do you think standing in direct sunlight all day is the same as standing in sunlight occasionally throughout the day? Obviously, much less damage is done when you reduce exposure time, particularly over long durations. Agreed that it’s very hard to be sure if we’re being damaged by the extra EMR caused by humans (I say extra because there is a TON of natural EMR around us – not just from the sun). Some, however, don’t feel like being the guinea pig and that, to me, is quite understandable.

            First off, there is plenty of research showing harm, the most recent from a University in Montreal.

            Secondly, more than a few countries are recognizing harm, and doing something about it. Because your corporate owned government sits quietly, does not change a thing,

            Finally, it is good to get away from the EMF in order to let your body heal. A faraday cage is good for sleeping time

            Actually WiFi and the signal it puts out are actually horribly bad for the human body it actually has been proven to break down DNA in rats with a fraction of what is legal in the US. Even out red blood cells are affected detrimentally by just a small exposure to these kinds of waves and it’s the waves in Smart Meters outside your house in every cell tower it coming from every phone coming from literally everywhere so there really is no way to avoid it by that you try to avoid it a little bit it could be the difference between you not getting brain cancer or if you’re a woman breast cancer from where you hold your phone there or just prostate cancer from guys having it in their fucking Pockets like do a little bit of research on that man it’s it’s really really bad I’m maybe read behold a pail Horse weapons for silent Wars. All the research that’s inconclusive whether it’s bad for you or not are done by the communications companies somewhere around 85% cuz Z independent studies find 90% negative results and there very earnestly persuaded not to publish it all goes back to who’s controlling all this and I’m the reason most people started prepping in the first place whether they know it or not that’s because the Deep state the fires the Caravans the drug epidemic all manufactured by the Deep state the Bilderberg Group Chancellor 300 Illuminati the 13 families whatever you want to call going to call it where then they will cause the crisis they will cause the ENT Institute in that they might just shut down the grid only time will tell but I believe it’s going to happen soon

          The Inverse Square law in physics limits how much exposure you have to low power EM emitting devices. If you are concerned about your neighbor’s wifi bombarding you with RF energy, the energy level you are exposed to is really very small. You would have to be within a foot or two of the antenna to even be concerned about exposure.

            How would you know that your neighbor didn’t put his mini-microwave oven called 2G/5G modem on the other side of the wall where you keep your head at night? Brains are composed from huge organic molecules like proteins and RNA, DNA etc. For these molecules to be functional they have to keep certain conformation. The conformation (spiral e.g.) is kept with very slight physical bonds, like Hydrogen-Oxygen polar bonds, which can be easily damaged. Resulting coagulation of your brains can result in messed up immunity system and all the kind of problems: from obesity up to brain tumors. This is a fascist terrorist technology with no legal regulation.

      I would disagree with that!
      If High frequencies are blocked then low frequencies will be also, but not visa versa.
      Here’s a good way to see it. The lower the frequencies the longer/larger the wave length and the larger the holes can be in the screen mesh. AM radio is so long/large that a highway overpass will block the signal but not a cell phone.
      If your Faraday cage blocks a UHF hand held walkie talkie, a cell phone, an AM and FM radio you’re probably good!

      The AM test doesn’t simulate EMP very well either which is obvious based on the fact that the AM broadcast doesn’t destroy any electronic equipment within it’s range. If you want a severe test take a cheap digital watch or cell phone or whatever test object you want and place it in your preferred container design and microwave said container for 10 seconds. If you want to make your microwave’s life easier, 5 secs would probably be adequate.

    I offer up to the internet the lowly paint can. metal,bail wire handle, unlined, durable, waterproof, fire resistant. and faraday enclosure. sure it wont hold a ton of gear, but a couple small electronics easily. hard to open. perhaps, but who doesnt have several ways to open a paint can if not in their EDC, then at least in your whatever you call it bag. Another simple solution is to duct tape a paint can opener to it. they are less than $10 from a home depot type store. and tons of uses after an event. pack small items inside clothing for padding so you have an extra pair of socks, a towel or t-shirt that could come in more handy than some foam padding in the following days. prep on 🙂

      Make sure that there is a good electrical connection between the lid and and can or it will not be a good Faraday cage. Paint cans often have thin non-conducting coatings inside, which might include the connection between the lid and the can. Excellent idea, I have used it.

        melt some solder and poor it in the groove along with some solder paste. scrape the grove as well I used a small dremel brush. tin the lip of the can and you will have a good connection. I would do the same down the joint of the can to cover the small gaps that we cant see but a RS could sneak in

    C Davis – have you tested any of these? You have some good ideas, but some are not so good. Any metal enclosure for which there are gaps between the lid and the “can” will allow significant rf energy inside the can. It is imperative that these gaps be closed with conductive material such as aluminum or copper tape.

      I have tried two of them and call BS. When the cardboard-box-aluminum-foil one (#3) didn’t work at all, I assumed that the foil was too thin or the lid didn’t close well or whatever; but then I took a metal tea-tin (#9) with a super-tight seal, lined it perfectly with cardboard… and it was totally useless.
      No wonder all the other sites with “how to build a Faraday Cage” instructions always require fancy metallic tape to seal it, and even THEN it isn’t perfect… Pfft.

      • Steve January 15, 04:53

        You don’t need any tape. If you want a simple test of concept take a verified working cell phone. Put the cell phone in an all metal kitchen pot with metallic lid that simply fits the pot correctly. The lid does not need to screw on, be clamped down or anything extreme. The phone will not ring when called when inside the pot. No tape or any other special methods are needed. Sealing it airtight or anything close to it is not necessary either. Many Faraday cage designs simply employ relatively fine wire mesh that you can see right through. The electrical charge doesn’t flow through the gaps, it flows around the outside of the cage. To see a demonstration of this concept in reverse, look through the door of your microwave when it’s running. You can see inside, yet your eyeballs don’t cook in your head and the cell phone in your pocket is not destroyed because the microwave energy does not jump through the gaps in the waveguide in the door. If you don’t think this at least roughly simulates EMP, stick the cell phone in the microwave and run it for 5 seconds and then go get a new cell phone. You don’t have to block 100% of the EMR from an EMP either. You just have to block enough to remain below the threshold where damage occurs. Your electronics are bombarded with low levels or EMR 24/7/365 anyway and they are not destroyed.

This to dissipate the electrical waves from leaving the microwave. Works to keep waves out too. I have found a couple of others and have them on a shelf in a metal cabinet, in a metal building. Keep 2 way radios, ham radios, electrical parts for my older cars, and such inside.

    Any container made of any material will do. Just be sure it is completely wrapped with foil. By the way, Mylar is not foil. Tin foil, aluminum foil, You know, the stuff you wrap your baked potato with. You can also use wire kennels, Chain link or welded wire. Thing is, don’t forget wire screen on the bottom too. If they are sitting on the ground, you propbably won’t need the bottom covered. Not so on your floor. The energy wave will rebound up through the floor unless it is just a slab of cement on the ground. If you have a metal garage, Park there and you should be fine. Most cars would be unaffected anyway. They are a kind of Faraday cage themselves. May be some minor inconveniences but for the most part, most cars will withstand an EMP just fine.

        A Faraday cage does not have to be grounded. A poor ground will actually interfere with the Faraday effect when protecting from an EMP as the high current flowing to the ground wire will prevent the Faraday cage’s surface currents from exactly matching and cancelling the wave (which is how it works). In general, it is safer not to ground it; to even insulate it from ground.

        Reply to this comment
    • BillH August 5, 05:01

      Might help, might hurt. There are actually two different ways to block an EMP wave. A Faraday cage, which is better not grounded. Or, a well grounded shield that stands between ground zero and the item being protected (because the wave is straight line, line of sight, and does not “turn corners”). A poor ground (which a simple chain would be) is unlikely to be an improvement.

The floor is 12′ concrete heavily reinforced with rebar and pillars going into the ground. Because they used heavy cranes they had to have everything beefed up! The roof is tin and is help up by steel girders like you use on the highway. We sometimes say that we live in partially built Faraday cage!

    I think a chest freezer or refrigerator with motor and internal plus eternal heat exchangers removed with aluminium foil grounded to the outside casing blocking gaps would be ideal for the job. Even without modification because of the insulation by just placing items in a heavy duty bin liner would probably do the trick Simple but effective.

        The radio test is just a basic proof of general concept. Commercial radio transmissions through the atmosphere are obviously not a good simulator of EMP or they would destroy many electronics within their transmission range as EMP would, when in fact they destroy none. Inversely, you don’t need to block 100% of EMP just like you don’t need to block the numerous EMR signals your electronics are exposed to from radio transmissions. You just need to reduce the the EMR below the level that will damage electronics. Look at it this way: If you can hold your cell phone next to a running microwave and it’s not damaged it’s likely it won’t be damaged if stored inside the NON-RUNNING microwave in the event of EMP. If you want an example of what EMP will do to unprotected electronics, stick your cell phone in the microwave and run it for a few seconds. Make sure your contacts and other data are backed up because the chance of needing the backups is 100%. That’s a much better, albeit harsh, specific simulator of EMP than the unshielded low power radio transmissions you are basing tests on.

    To preference my qualifications I am an electrical contractor and trained by the Navy in electronics.
    I have devised some ways to test the effectiveness of a Faraday cage. The idea id to block the pulse from going into the box. Take a simple RC toy and put it in the box testing it out before to assure it works. With your controlling device and the enclosure secured try to operate the toy. If the toy functions with any of the controls the signal from a pulse will enter. The use of a radio may also serve only it must be set to AM. A battery of six or more volts will do well. A wire connected to one pole and touched against the other will give you a spark and you shouldn’t hear any static from the speaker. If you do then the pulse entered the box. The power level is small so if the signal enters at this level then the powerful pulse will also enter. I do hope this is of use to you.

      Hi Gramps….
      you seem to have the most authoritative and rational voice in these comments I’m reading … I’m trying to discover , is there some way I can build a simple Faraday cage that someone could sleep in to get restorative sleep away from the new 5G radiations that are going to be all over the place ? some people have said that the size of these wavelengths will go through ordinary aluminum screen mesh (?)
      what do you know about this ? is there a specific size of mesh that would block the 5G radiation?
      Thank You

    When we bought our house the previous owners left an early 1960s fridge in the basement. Turned off, unplugged & completely clean it makes a fabulous large Faraday Cage. I lined it with foam padding & it’s in a basement room with only one small window. Works great. My cell phone gets no reception inside.

    • BillH August 5, 04:22

      Again, cell phone test is not reliable. Use AM radio instead. Refrigerators have an insulating strip around the door which results in a gap. A Faraday cage must be a conductor all the way around, without gaps. Turns out that any straight line gap or even a non-conducting seam acts like an antenna, allowing the wave inside.

        I am under the impression that solar chips, being semiconductors, are sensitive to E1 wave. Less so than miniaturized semiconductors, but still might fry. And if connected to unprotected wires (which is usually true), then the E3 wave will likely take them out, just like anything else plugged in any way.

    Nuclear war is NOT survivable. This is a simple proven scientific fact. The fallout from just one failed nuclear power plant is enough to destroy this country. There are over 100 Nuclear power plants in this country today.

      You are mistaken. It is not “a simple proven scientific fact”. Real fact is, radiation from a nuclear bomb (different in character than a nuclear power plant) has a short half-life. A couple weeks later the levels are no longer deadly. How many died from radiation in the two atomic bombs dropped on Japan? Far fewer than from the blasts.

      A nuclear power plant is a different matter. Worse. Both Russia and Japan have suffered from their failed plants. But neither country is a unlivable wasteland either.

    • BillH January 15, 03:33

      Might work by blocking the wave and bleeding the power off into the ground. But only if the grounding is extraordinary, way beyond the usual small grounding straps. To make it a true Faraday cage, it has to conduct on all surfaces, even the ground, and with no non-conductive gaps anywhere.

      So add a steel floor and make sure there are no non-conductive gaps (even if almost zero size) as such gaps act as antennas to bring the wave inside.

      A metal shipping crate with all seams welded and a conductive gasket around the door would work.

    I’m a little lost. When you make one of these out of a trash can, popcorn tin and so on it mentions completely insulating the sides and lid to keep your electronics from touching the metal (the way I understand it). In the comments, someone mentioned just wrapping your devices in tin foil. That seems contradictory. Can you wrap your devices (batt operated radio, scanner, old phone etc) in several layers of foil or not? Not sure how old this article is, but figured I would give a shot to asking my question and someone maybe could help. Thanks!

    Interesting, but in the opening paragraphs I notice a big red-flag…
    The statistic of “90% casualty rate” is SEVERELY misleading. It should be noted that a “90% casualty rate” is applicable to 90% of ELECTRONIC DEVICES, not human lives. In my opinion FAR too much time is spent on electronic protection. So what if you save your radio? The broadcasting station will be damaged beyond use. So what if you save your cellphone? Do you think the signal towers will be delivering service, even then who on the other end will be receiving your calls/txts? So what if you save your generator? You’ll still get shot trying to buy gas. And even further, you’ll be saving your generator to power what exactly? Your radio with no channels, your cellphone that makes no calls?
    I’ve always been the type to “prep” in the OPPOSITE direction… WAY too much emphasis is placed on the “technology” of survival. People have existed through wars and famine for THOUSANDS of years without electricity at all! We are becoming slaves to technology if we have to protect our electronics before protecting ourselves! Learn to farm, learn that solid stone is far superior to any aluminum foil lined birdcage, learn that when the world goes “off grid” it simply means we are set back to the time of our ancestors. If they could live and thrive in the 19th century, I’m sure we can too. But at the end of the day, I think most “preppers” are mainly “into it” for the technologies of it. The “thrill” of the science…. it becomes a fetish to “try and preserve 21st century life” in a time of crisis rather than true SURVIVAL. But just my opinion!

      The 90% casualty, actually death, not simply casualty, estimate for the US populace is based on electrical grid failure for a period of one year. The causes of death would be indirect with regard to the cause of the gird failure. Starvation, conflict, death by exposure, etc.

    Afternoon: I encourage the exchange of information and discussion for the sake of emergency preparedness. The suggestions illustrated here all try to answer the question of (A), how to make an affordable faraday box to protect sensitive devices. And (B), how to make one that I can open and close. I would suggest multiple layers of defense. Use alternating layers of a faraday bag, heavy ziploc freezer bag, faraday bag, freezer…Etc. The outside metal container is only 100% effective is it has no gaps, seals, spaces and you have a 100% insulation layer or layers. “Belts and Suspender” EMP bags and ziploc bags are an inexpensive way to improve the desired effect. Hope this is helpful.

    Reply to this comment
    • Hobbs December 28, 20:19

      I should have proof read my initial response before posting. Use the metal container that you feel provides you with the best seal. Use the alternating layers of faraday bags and heavy ziploc freezer bags to cover each item in the metal metal container. Multiple layers of defense gives you the best chance of protection. If one layer fails then you still have additional barriers to rely on.

    Think of Radio signals as waves. Naval submarine radio waves are huge, AM broad cast are large waves, Ham radio and international radio are shorter [shortwave radio], CB radios are even shorter, Channels 2 thru 13 TV & FM radio are from 50 meters to about 2 meter and a Micro wave oven are just that, SMALL.
    In an EMP event ALL these waves or frequencies happen at the same time and can create voltage in any thing metallic.
    Anything in a sealed tin can will get fried if it is touching the metal of the tin can, so it must be insulated will in the can.
    If I drill and 3/8 inch hole in that tin can any waves that are 3/8 inch or smaller will get in the tin can and fry what’s inside even if it is insulated from the can, so any hole larger than window screen will prove deadly to electronics.
    Voltage will travel in to the can on an antenna wire or charger cord charging the electronics, so don’t have any wires coming out of the can attached to the electronics.
    It must be completely isolated from the out side world and insulated from the metal walls on the inside.
    This is the most complete way I can describe the subject. You should be able to come up with a way to protect your electronic, but you can never use them, because in the event you are using them in the outside world and an EMP happens, its good bye for what ever is not isolated in the way I have described it.

    Great Comments and Inquiries Here…..(Thank U)

    Would someone care to comment on the use of reinforced aluminized fiberglass HVAC duct board to create a faraday cage if taped shut with conductive copper or aluminum tape with conductive adhesive. Figured that the prickly fiberglass could be sprayed with rubber sealer – more so for keeping fibers from your hands. These might be useful to encase HF Radios and other HAM gear for maybe longer term storage.

    Another potential candidate for a faraday cage might be 55 Gallon Metal Drums kept vertical or horizontal with removable tops that can be clamped shut and taped along with any of the threaded metal openings (taped). Easy to line with spray rubber sealant or EPDM (rubber roofing) scraps or cardboard. Store gear inside in cardboard boxes?

    The pasta box mentioned all the extra things for the car but one or two. Have your alternator set up to run using an external voltage regulator and keep an extra voltage regulator in a pasta box. I haven’t seen any internet videos or essays about the voltage regulator. The regulator is nothing more than a silicon chip.

  44. Steve January 15, 04:27

    The need to insulate the interior of the container is questionable. From day one starting in the 18th century, the Faraday cage concept was first observed by noting the apparent lack of any charged field on the inside of a non-insulated metallic container when the exterior of the container was electrified. The charge flows around the outside not through the container to the interior, insulated or not. Insulation probably won’t hurt unless it causes static buildup on the inside of the container due to the insulation material used, but it’s not a central or vital part of the Faraday cage concept either. Trying the cell phone experiment, the phone still will not ring when place in a non-insulated metallic container even in direct contact with the pots metallic surface. An all metal kitchen pot with snug fitting lid works well for the experiment.

    Well, lots of comments. I liked that someone thought to write this article and demonstrate that there are various ways to create a faraday cage or box and that it’s not difficult or requires a high tech laboratory and a degree in anything except experience breathing, reading and making stuff. This is such an easy precaution to take that I am thinking of making a few containers from all the tins I have saved and lining my ammo cans just in case it looks like an EMP strike is probable. Anyway, it’s an easy thing to just dump a few items into a can or box whenever you don’t need to use them, like before going to sleep and just close it.
    If by some chance any of these units fail, at least I tired. And then again, if any make it or they all make it, I’ll have use of my electronics.

    does the distance of the emp pulse itself have any effects. ground zero vs say 1000 miles away?
    as for the one comment. why would you save pix or an ebook if you cant use the item when it has no way of showing? not true if you save a ipad with all that data as long as you can store the info no it. and its protected then its its own viewable source.

But most of the suggestions above recommend cardboard as the insulator. Also, can you use electrical tape to secure the tin foil in place?

      Sounds like a good idea to me. I wondered about the use of cardboard as an insulator. While it’s true cardboard can provide some thermal and sound insulation, it is a wood product, and wood does conduct electricity. Plastic, with insulation, and another layer of plastic… does not. So yep – a Styrofoam cooler, especially one encased in plastic, makes sense to me. Just be careful not to mess with the aluminum foil as one tear or hole can spell catastrophe. So, perhaps put a couple of small coolers inside a galvanized trash can with a tight sealing lid, or a fifty-five gallon steel drum, then band it up nice and tight.

    Why shield a radio if it stops working when you shield it? It becomes dead weight. You only need a radio to listen to something all the time. And if it doesn’t work when you protect it then you don’t need it. that is the case with all the electronics that you put in a Faraday cage if they are locked in the Faraday cage for protection you can not use them so you don’t need them.

      I also modified an old file cabinet by removing the paint of the articulating surfaces and then covering those surfaces with conductive tape. I can open the drawers to put things in and out. Everything inside is also layered with aluminum foil and a mylar bag with appropriate insulation between each layer, of course. The file cabinet drawers also are really easy to line with cardboard because the box from a case of paper fits perfectly.

    There is a big difference between relatively low-power radio frequencies and high-power high-frequency EMPs. Foil may be enough to stop radio frequencies from getting through, but it is not substantial enough to handle the current generated by an EMP. Using foil to guard against an EMP would be similar to using 24 gauge wire for a car battery; it is likely to burn through. The Carrington Event of 1859 proved this point when it caused telegraph wires much thicker than foil to catch fire.

    what protection, if any, does a standard all metal building with a concrete/rebar flooring provide? metal doors but not 100% metal sealed?

    I think we need to read this article, Dr. Arthur Bradley, author of Disaster Preparedness for EMP Attacks and Solar Storms. There are some critical contradictions with this article. https://www.mdcreekmore.com/build-your-own-faraday-cage-heres-how-two/

    Enjoy these articles.. Very entertaining.

    Like to know where you came up with the 5% probability per year for an EMP event.

    Thank you for this information however, there us a lot of concern that the new 5G wavelengths are smaller and so my specific question is ….will they still be blocked out by aluminum screen? I just spent 9 years in a parking lot with 12 4G towers bombing me with 500 to 1000 times the radiation of nature ….but inside my aluminum trailer with aluminum screens over all the openings it was extremely safe….will this setup still sheild against 5G ?

    I clicked on the link you provided for everyone to become familiar with EMP and as you described it the biggest threat to America. Instead I had to watch a very poorly produced video on how to build a root cellar and it doesn’t mention emp’s. How lame.

    One issue folks, if the grid does go down all the nuclear plants will be off line. Now you really have a problem.
    Once the generators run out of diesel the pools start to get hot and the rods start to get hot then all hell breaks loose.
    I wonder if preparing for an EMP will even help us after the nuclear plants start spreading nuclear waste all over the entire US? What about other counties that will be in the head winds? It’s going to be a mess.
    I hate to be a Debbie downer but this seems to be an issue no one has brought up. Think living in a hole the rest of your life is going to work?
    May as well go dance in it and get it over with. I wish there was something more positive about this situation but it looks like there is only one outcome.

    What nonsense. none of those items will work. Even in layers they won’t work. Just use aluminum tape and completely wrap the box the item comes in on all three axis. Making sure you don’t leave any gaps. Then store that box in a metal cabinet or safe with insulating gaps between all other items, including the cabinet.. EMP protection is a layered process. The more layers you have, the more likely your item is going to survive.

    All the maps showing a single event over Nebraska is silly. There would be a least 8 to 12 weapons used over the US. You can count on being in the highest intensity section of the weapon.

    Military equipment has at least 5 layers. They also have filters on the interconnecting wiring. They have selected individual components that are ‘sized’ to resist the voltages. The boxes must provide protection. The vehicle body is specifically configured to provide protection. And, there are other measures, I cannot discuss.

    In your case, I’d shoot for 3 layers of protection.
