5-Minutes DIY Tested Faraday Cage Out Of A Trash Can

Editor’s note: This article was written by one of our readers, Susie Harrison, who published a trilogy on post-apocalyptic America that you can check out here.

Even before the pandemic hit the U.S. I had seen the videos from China and knew it was at our doorstep by late December, early January. I had already done my shopping (including toilet paper) before the ‘empty store’ crisis hit. Then as violence broke out in the streets, I knew our turmoil was not finished. The women in our family, we began to prep, even while being mocked by some of the boys and men around us.

Realizing that there was a huge potential for possible grid/cyber outages around election day, we got busy. My mother in California, my daughter in Wyoming, and me, in Nevada. I wish we were all together; as a team we would be formidable.

Faraday cages became important to us realizing we had refrigerators, freezers, and generators. My mother went all out, while I could only afford small power sources… and a mini frig. Most things we depend on may be small but could very well be rendered useless in an EMP. I did my research. With a little creativity and a son who likes to help, we successfully and affordably designed our own faraday cages.

Here is what you need

  • 20 Gallon (or larger) Behrens Galvanized Steel Trash Cans with locking lids are recommended, however the ones with locking lids were sold out. I got the regular lid with foil tape. Cost app. 40$ each at Amazon, check your local hardware store for brands and prices.5-Minutes DIY Tested Faraday Cage Out Of A Trash Can
  • Aluminum Foil Tape: I bought Scotch Aluminum Tape for app. 6$ at Amazon.
  • Extra Cardboard
  • Utility knife (or in our case a kitchen knife since we could not find the toolbox)
  • Guerrilla Glue and Tape (or strong glue packing tape) if not using a tape-able material.

Another way to insulate your faraday cage, which I like the results much better, was some extra carpet padding I found in the garage. If you use this however, tape is of little use, so any kind of strong glue should be efficient.

Cardboard, Carpet padding, and Bubble wrap are all good to put a barrier between your metal protection and your electronic devices. If your objects are touching the metal, or your barrier has open spaces, this will reduce or remove protection for your cell phones, laptops, computers and any other electrical device inside.

Directions

1. You can use the box your cans came in (if shipped) or other material. Put your trash can on flat cardboard and cut around the bottom of the lid in a circular fashion. Repeat. Now you have 2 circular barriers, one for the bottom and one for the lid of your metal can. You can use Guerrilla tape or packing tape to hold the inside together.

5-Minutes DIY Tested Faraday Cage Out Of A Trash Can2. If using cardboard, or your box place a large piece in a circular motion and/or cut up other pieces to fill in the entire sides of your metal can. Use tape to fasten the bottom, lid, and sides securely to the can. I found with the carpet padding, I had to use glue, which seems to work fine.

Although my carpet pad barrier looks loose at the top, it helps seal around the top of the lid around the pad lining the lid. The day you decide to seal around the top of the lids with foil tap. Both insulators (upon testing) are solid faraday cages.

5-Minutes DIY Tested Faraday Cage Out Of A Trash Can3. Last phase: Seal around the lip of your metal can lids tightly. You may wait to do this last part till disaster is at hand. However, you can even test without it and get good readings. You just don’t want to waste foil tape and it’s sticky.

Although my carpet pad barrier looks loose at the top, it helps seal around the top of the lid around the pad lining the lid. The day you decide to seal around the top of the lids with foil tap. Both insulators (upon testing) are solid faraday cages.

I would like to add a tip for power sources and generators. I can’t speak to large generators as much, but I’ve found that if you put your smaller power sources in their original packing and place them in a box, put a few layers of aluminum foil securely taped around the boxes… you’ve just created your own faraday cages for small generators. This saves lots of space in your metal cans for other things.

Do not forget to wrap any solar panels for those generators as well.

To test your devices, you can use cell phones or a radio. Some cell signals are stronger than others. We tried this with all our phones. We put each of 4 cell phones inside the faraday cages (both padded cage and cardboard cage) 3 of them, when called from the outside line, went straight to voicemail. Nor did not ring in the cage.

My son had a strong phone and it only worked on his some of the time. After wrapping his twice with foil, we finally got the desired result. The padded can worked better than the cardboard can.

The best way to test was with a battery powered radio. You can clearly hear that the music playing starts to go to static as we put it in the box before even introducing the lid. With the lid on we knew they signal was completely gone.

There may be a video below to show our garage redneck testing on the radio and how well our Faraday Cages work.

    a critical issue that never gets addressed in regard to Faraday cage design and builds >>>

    most probably neither an EMP or CME will be a single occurrence event – there’ll be follow-up bursts for days/weeks/years to the initial blasl that could be even more powerful …

    that calls for a “use and scoot” usage – the Faraday cage will need to be uber uber durable for almost constant entry & closing …

      From what I read, aluminum alone will NOT work. They do have something called EMP cloth and it’s made from several materials other than aluminum. It has nickel in it also. Gotta do more research. To test it I seen a video showing to use a small am radio (it operates on weak signals) and a cell phone(it operates on stronger signals. If both doesn’t work it’s good.

    I have a large 9500 Champion, dual fuel generator.
    I want to build a doghouse for it to be used outside. What kind of metal would be good for dual purposing the doghouse as a faraday cage?

    Also, the generator doghouse has to be ventilated, and this will interfere with faraday cage efficiency. So, are locking vent covers going to be enough to seal the faraday cage?

    Has anyone ever done what I purpose?

    Thanks!

      Hey Tal,
      I use to run power generators in the military.
      And put mine in a hole that the generator just fit in depth wise. Being air cooled, you will need to have more than just exhaust vent.
      I don’t think with a faraday cage that you can allow any openings.
      I have 2 generators and plan on keeping them locked down until needed, if EMP or CME is forecast or if not foreseen, at least one will be safe.(The dual-fuel will be safe)….

      Flat steel panels which you can buy at some bog box stores or from a metal fabricator in your town. Leave room for vents for your generator but make plates that fit over the vent holes. Screw them down against the plate covering the walls of your “doghouse”If they are a snug fit, the electron path will be interrupted and they will prevent any leakage into the interior. Make sure no metal parts touch any part of the exterior walls. You can sit the generator on cardboard to insulate the feet from the floor of the “dog house”. Be sure that you cover the bottom of the structure with the sheet steel.

      It doesn’t have to be special steel designed to stop bullets, even aluminum sheeting will do the job.

      Reread the above article so that you feel you clearly understand how the items inside must be isolated from the outside walls.

      Don’t be afraid to ask clarifying questions. The only dumb question is the unasked one.

        Hey Chuck, Thanks for the FYI!

        I’m thinking of building the wood frame for the doghouse, then cover the entire outside with carpet pad, then cover the pad with sheet aluminum. There will be a cement pad to set this on and I’m going to make it so I can lift the entire doghouse off the slab to get the generator in & out. I’ll have the sheet aluminum extend down the sides a couple inches so it slides over the edges of the slab to seal everything up. I’ll do the cellphone thing to check it.

        The only real drawback I can see is where the soft copper propane line & wires come in. If I run it under the slab and up to the generator will EMP energy get in from underground?
        Will EMP energy follow the copper pipe that will be coming from the house and will be exposed to the elements for about a 6’ run before going underground and will be connected directly to the generator? Would a rubber connecting hose between the generator & copper propane line insulate the generator?

        Sound like a plan?

      TAL Just wondering, would an electric magnate work for a connection outside? If there was a jolt in the system, it would drop off. They were using this in prisons, where any interruption of the electric meant gates and door closed and locked. If so, that means a ventilation system would be easy enough. Just wondering. niio

        red the speed of the EMP event is less than the proverbial blink of an eye. The time for the flap to drop when the “jolt” occurred would be too slow to protect.

        So if an EMP occurred all prison doors would be locked?

        There has to be a non-electric backup I suppose?

            Technically, a lightning strike is an EMP, just more local and weaker. most electrical things which are not plugged in or otherwise isolated, will likely not be affected by an EMP strike. some of the more light duty electronic things, like computers, cell phones, t.v.’s, radios and the like COULD be affected. Unfortunately, there is no one answer fits all, as we don’t really have much information from physical testing…The government kinda squashed that…go figure.

Wrapped edges in grounding wire tape. Put the tops on and it worked great. Those stock tanks come big enough to fit a generator. good luck

      A Faraday cage does not have to be solid. Mesh works better than anything else. I always see people make “cages” and never ground them to earth which is a total failure. Also remember most comments about EMP energy are hype. We tested a 1970s era 4ESS communications system in a military HEMP camber and it worked perfect with no shielding. Long transmission lines absorb a lot of energy and will fail. Short length chip circuits make poor antennas and do not absorb much EMP energy. A well grounded generator case/frame in permanent installation is going to be fine.I have a small building over my gas generator with driven rod ground and code wiring to a manual grid disconnect. I have manual doors on both ends to allow air flow when running. Protect your electronics that have antennas because they absorb EMP. Everything else is going to be ok.

    A while back I got curious about aluminum duct tape, so I took a 6″ piece & cut it in half lengthwise. Overlapped the ends so I had an 11″ strip and stuck that down on a board. Then I measured the dc resistance from end to end. It was an open circuit. The glue is an electrical insulator. You’re forming a very low value capacitor between the top of the tape & what you are attaching it to, so as a gap sealer against an emp it may/may not work. A capacitor will pass ac, the higher the frequency the better it is. Ran the same dc test with kitchen aluminum foil and some copper tape that had been discarded because the glue had dried out and got the same results. Kitchen foil should work if the strip was flipped so the shiny was making the contact across the gap. Taping the strip with packing tape would serve to hold it in place.

    Tal
    Your air intake problem can be solved by using metallic window screen (not the cheaper plastic they like to sell). Screen will restrict air flow so the opening will have to be sized to allow the air intake required.
    Your main problem is getting rid of the exhaust.
    Is your system wired so the gen comes on automatically when the power drops out? If so I’d suggest getting a spare control board & putting it into a separate, well sealed faraday cage. If you have a manual start system sealable hatches would work for power outage & the monthly exercises. (Generator manuf suggest a monthly start & run to make sure the system comes up to voltage & frequency as well as getting the engine hot enough to evaporate moisture that has condensed internally.)

Some of the writing is pretty slick like the Forstchen books, but my favorites are the ones written by non-professionals who are pouring their real life experiences and a big part of their heart into their work. Ms.Harrison’s books sound like the latter, and I’m putting her next up on my Kindle.

    I will tell you that using a cell phone or radio to determine if your faraday cage is working, is worthless. An EMP pulse will be ten to a hundred thousand times as strong as any signel you are detecting. Even the CME will be a hundred or more times as strong. Determining that a cell phone needed to be wrapped more proves that you only have a metal box and not a real faraday cage. Sorry to dis-illunite you.

        CC: I agree. I think a great many folks just cannot imagine what life will be like after either a CME which is a sure thing or an EMP or just a significant attack on our grid system.

        Generators are fine for a short term electrical outages, but having electricity for your home won’t be much help for urban peppers when the emergency generator that runs the sewer system fails for lack of fuel or the emergency generator for the water system fails for lack of same or, as in the case of the Thomas Fire a couple of years ago, didn’t work at all because the city folks at the water plant had never tried it to see if it worked. They installed the system and didn’t have a plan for regular testing of the system and so when the electrical infrastructure that ran the plant was burned in the fire and they tried to start the emergency equipment, it didn’t work! The resulting litigation is still wending its way through the preliminary stages.

        While telephones with data stored and laptop computers with data stored can be helpful if stored in Faraday cages, as communication devices they won’t be much help when the cell towers fail due to overload or the backup batteries go down for lack of electricity.

        So many folks just don’t get it. It will be “Welcome to the early 18th century without the infrastructure those folks had.” Sure, we will have knowledge they didn’t have. We know about bacteria and viruses that they didn’t know exist. We know why bad water makes us sick and we know how to avoid drinking bad water. We know — or should know — that bat’s wings, newt eyes, cat’s liver have no medicinal value. We know that oxen poop, no matter how fresh is not good stuff to put on wounds.

        But, alas, many of us lack lots of knowledge that folks had then. My knowledge of animal husbandry is sadly deficient. It has been over 50 years since I saddled a horse. I think it would come back to me, but both the horse and I would be fairly uncomfortable for a while. I know zero about helping a cow deliver a calf. I know that sometimes one has to reach into the cow and drag the calf out but that is the limit of that knowledge. I know how to slaughter chickens from having watched my father perform the task but that was 70 years ago. The first couple of chickens I have to dispatch will be a sloppy job, I am sure. As far as the rest of chicken husbandry, it’s pretty limited.

        For urban dwellers, unless we happen to have family or friends who own a small truck farm, it is difficult to really get hands on experience. Sure, we can read books and that is a big help but it really takes hands on to learn all the things the book didn’t mention. We are really going to be scrambling when a CME hits if the folks in power don’t do something about protecting the grid.

          Given your worst case scenario I think even a lot of well prepared homesteader types will find they weren’t really independent of the grid. Farm animals need feed, and most people don’t have the land or equipment to grow large quantities of hay and grain so they depend on the farm store. My neighbors that try to free range chickens have high losses to hawks and loose dogs. A surprising fact for me to learn was that most horses in the U.S. are not fit for work, they are basically pets. Put them to pulling a wagon or plowing and they will up and die.
          Then there is the problem of boots and clothes, if you are doing ag work full time you’re lucky to get 3-6 months out of a pair of boots, mud, water, and manure eat ’em right up. Country living is tough, that’s why almost all pre-industrial cultures had serfs and slaves.

            Free range chickens kept in pods like Joe Salertain does and Pollo Royal in New Mexico do not suffer high losses; nor do Amish who go free-range. These are high volume producers. At one time, all poultry was free-range. The profit is high enough people are investing in livestock guard dogs. Sheep ranchers have said it’s harder to raise a sheep than poultry when close to town.

      Did you ever raise geese? Usually friendly, funny, tasty, and in breeding season ganders attack to kill. Other than that they make great pets. The term ‘goosing someone’ came because of another bad habit they have, but we all have our little hobbies.
      Best breed is Chinese. Lightweights, but hardy. One of Mom’s used to come to the back door and tap on it when she wanted some bread. Best ting, one gander will cover from 3-7 hens. European geese are monogamous and mate for life. African geese are the hardest to raise, the most aggressive. Chinas can lay up to 150 eggs a year in warm climates. China is said to have a new type that lays year-long. Euros lay about 50. In either case, if you steal the eggs, they can be put under Muscovy ducks or broody hens. One other thing good is, goose eggs can almost freeze and still go on to hatch. Yeah, Mom had her poultry.
      You will need good pasture, and move them every few weeks. That’s true of any livestock to prevent build-up of parasites and flies. Up your way, earthworms will clean up their messes.
      for eggs, best bet is the Asian breeds, which lay better than chickens on less feed. Were I farming up that way, I’d raise a flock of them just for eggs to sell. Waterfowl eggs are best for baking. (too much time spent as kitchen help when I was a kid, erk) niio

        I lived in an old house on a ranch years ago. There was a flock of geese I wasn’t responsible for but always enjoyed them being around until I made the mistake of giving them a little corn. I only did it once but from then on the whole flock gathered outside my bedroom window at dawn every morning demanding corn. And waiting to goose me.

    A faraday cage needs a grounding wire running to a copper rod in the ground to properly dissipate the EMP charge. DO NOT connect it to your house ground.

    Can spray insulation foam be sprayed inside a metal drum to make a faraday cage? Is foam electrically conductive at all?

    Quick question – I’ve been told that a good solid fire-proof gun safe locked and positioned in a lower level basement works as a great faraday cage. If there is any truth to that, it would be good to know. I always welcome a second opinion. And would like to also thank you in advance for any help you can provide.

    One thing I see missing in the story is the need to ground the “cage”. Attach a grounding wire to the trash can/cage, and connect it to a copper rod that you can sink into the ground; the longer/deeper, the better. This will shunt any EMP/CME energy to earth ground.

    For all who have questions about protection from EMP/CME, Dr. Arthur Bradley writing a new book, “Everything You Wanted To Know About Sex” — oops that title is already take “About EMP/CME” not nearly as intriguing as the first title but certainly of more concern.

    On a more serious note, he has already written one book about gigantic electrical surges and in that book he details the tests he used and the results he got.

    Interestingly enough, he found that plain ordinary duct tape blocked electron leakage better than the special electronic tape that was considerably more expensive. He described the tests he performed, the products he used and the results he got.

    When his new book hits the market, I will post the information on this site so we can avail ourselves of some reliable information based on actual measured testing.

    What kind of dung is everyone smoking? If you think your electronics are going to be useful after the power-grid goes down, Good-Luck. Where do you think the cell phone signals will go to – come from. How much fuel can U possibly store and for how long will it stay stable before it goes bad? You think U will be able to hang on to a gen. when the really bad guys want it to cool their beer? What good will a computer/I-pad be without an internet to draw from? If/when the Grid goes down, all electronics and power gens. will be just so much excess weight. Better to learn how to live totally without anything electronic. A Faraday cage is just so-much wasted effort. Nice to dream a little though.
