Dr. B...you are the Bob Ross of Faraday boxes! Outstanding video!

I just wanted to say thank you. Canadian Prepper mentioned you in one of his videos and what can I say - your videos are amazing. You don't just tell people what to do, you prove it.

Great info, but I couldn’t help cringing thinking about those tabs scratching up that table! :)

Bet that tabletop was in great shape when you got done.

Awesome build and demo Doc !

Love this guy! Ty for what you do for us average guys! God will bless your efforts.!

Another fantastic video. Thank you so much!

Great new product! Thanks for this very thorough demonstration :-)

Excellent video !! Thank you.

Short cut: just jumo to 10:00. This is a perfect example of a smart guy making a simple project difficult 😂. Just make a box and wrap it with this conductive barrier.

Awesome. May have to get me 1 but I'll be picking up a few of your books for gifts 1st. Have a great Christmas&New Year Doc!

Hey Dr. Bradley! Long time no see :) This is really nice...thank you for taking all this time to show it to us. PS> I love it when I get my Uline catalog in!

Great Video Thank You

Nice work.

Great video! Can't this also be done with a cardboard box (as you mention in the description), Heavy foil and metal tape?

Nice work. I wonder if a metal safe or metal fire box that has a good sealing lid would be an easy EMP box. I'd be curious to see how that would perform stock and then with your tape and gaskets to make it better!

THKS

What about Sandwich Panels with PU Foam inside and on layer of 0,4mm of metal sheet on both sides?

Good day sir! I caught you on the Canadian preparedness Channel just about an hour ago. I'm so glad that I caught that and was able to subscribe to your channel also. I had the same idea that you just showed tonight but you filled in the blanks for me thank you so much. I will be building a box such as that. But I also want to build one to cover my generator but I also want to be able to get into my generator Without Really tearing things apart. So I was wondering if I could use small rabbit wire or even metal screen wire to wrap my box in? Mainly using the wire to be able to open it up to Crank It Up should I need to in case of a regular power outage. Wouldn't that be the same as wrapping it in the conductive material that you have wrapped the Box in and if I am able to use the wire should I use it as plan naked wire or can it be rubberized wire? I certainly hope you can answer these questions for me. Also have one more question. I am just before getting an EMP Shield for my home and if my generator is connected and to my house grid will it be safe. I'm sorry these are difficult questions but that's the questions I have. I certainly do hope you get to answer these questions for me. I wrote down the website you put on the screen for the kit and plan on getting the kit. Please have a great day and stay safe and keep your powder dry! This is in response to the alert box that you demonstrated the other day. I tried to purchase one or get in line for one and somehow someway I ended up with two in my cart. I tried to delete one but it would not work and I still would like to purchase that product. I hope you read this

I built one just exactly like that using heavy duty foil. What’s the product you used? Mine has a lose bottom and attached top so the top and sides fit over my Hysolis solar generator. The bottom sits on rubber casters, which makes moving the 130lb beast around very easy.

It works great but remember when you Fold the EMF paper INSIDE the Box, you bring inside the Box the charged paper! I got a 3' X 22" Uline Box and the correct size EMP cover, and I'll do it the Same way but I'll be careful to keep the foled-in pieces as small as possible and use simple duct tape.

What is the official name for the interlocking strips/tabs used in the video? Where can they be purchased?

Excellent video. Very interesting and worthwhile video. Can one make such a Faraday Cage (Box) using a heavy cardboard box with two layers of aluminum foil covering the exterior? Can one use a steel trash can (with a tight fitting steel lid) and with a cardboard box in the trash can's interior? Will these Faraday Csges suffice for a Carrington-level CME? Many thanks.

45 degree cuts on the corner will give you clean folds

Thank you so much for taking your valuable time with this project! I have a question though concerning the construction of the box. Assuming that conductive tape is more expensive than say duct tape or gorilla tape, would it not be more reasonable to use less expensive options on the areas where the conductive sheeting is being attached to the plywood? My assumption being that the other attaching panels would either not be touching those areas or that the conductive sheeting would be overlapping them reaching other conductive material (where you would use conductive tape). Am I being clear about this? It’s a bit hard to get across but perhaps you understand.

Nice video, What did you use as shielding material? How much does it cost? However, Military EMP Bombs create magnetic fields on the order of hundreds of millions of Gauss or more. The EMP wave is a pulse with near DC characteristics and very little high frequency components. Its been a while for me, but in the 80's working with the Air Force and General Dynamics on EMP detection and protection, the only way to generate such an EMP is from a Nuclear Detonation. We had to scale up our experiments in the lab to determine a real tactical EMP event (still classified). As a rough matter of scale using 0 dBm as 1 mW/50 Ohms. In your low power experiment you excite with 100 MHz at -7 dBm (200 uW) at a range of about 100 mm, and read -73 dBm (about .05 nW) which is 66 dB attenuation inside. But in reality, a real DC EMP event will generate (what I can only say): a big enough pulse to get through in your case at about +40 dBm or more (10 W), that is enough to destroy the electronics inside.

Great video. So... my question... If the solar power station and the panels that go with it, are stored the the cardboard boxes that they shipped in.... can I just use this method to completely seal the boxes with this material and tape? Rather than building a box like this? My other thought was an EMP blanket big enough to just cover them up.

Is there any advantage to adding a braded ground cable from the outside of the Faraday box to a ground rod?

Oops, forgot to ask you something in relation to my earlier post. Do I need to ground the aforementioned faraday boxes I asked you about? I've heard that I should just leave them isolated, on a rubber floor mat, but I've also been advised to ground them to a cold water pipe, or to an 8' ground rod via 4-6 awg cable. Please advise.

Wonder if notch covering with tape is needed. Follow up video without those tab coverings?

I made a box like this one except I connected each corner with 2 cabinet hinges both 3 inch. I can just pull the pins and each section fits together perfectly for pins to be replaced. Tape and foil is standard. The question is if boxes and other types of containers are then wrapped with chicken wire type materials can more protection be achieved. I was also wondering why you didn't line the inside with cardboard so that no possibility of contact with the outer surface can be made

What is the part # on the conductive tape??

Would using Mylar for a Faraday Cage be good?

Hi Dr. Bradley, I'm moving to a flat that's located next to a distribuiton transformer, I would like to know what can I do to reduced EMF coming from the transformer room to our bedrooms. The transformer room neighbours our wall, and it distributes power for 42 flats. I was planning to install a metallic wallpaper, or stainless steel panels, or even EMF shielding wallpapers in my son's bedroom wall (that nighbours the transformer room), but I'm not sure how efficient it would be. What is your take on it? Many Thanks.

I have read where some say the box needs to be grounded to a grounding rod or something. Yours was not. What are your thoughts on this?

Where do I buy the conductive barrier at

What is the conductive material called and where can it be found?

How would flowing electricity inside of a Faraday cage effect it's protection? For example, say I hook up a cellphone to an external battery pack and set it in a Faraday cage box to charge (I understand that could become a fire hazard, but I am using this theory for the sake of example). Would the flowing electricity within the box increase the risk of a shock getting through the barrier(s) at all? Also, would the hinges cause any risk of conduction or jumping to something that sits too close to the corner? Thank you!

Does anyone know where to get those metal brackets being used on the box build? I can't seem to find them online.

Would it be a good idea to to use a non conductive tape to tape all the edges, so there is less chance the metal will cut into the conductive material?

WHERE CAN I GET THE FABRIC ?

How about wrapping cardboard boxes in foil and sealing it with metal tape? Will that work?

I have a large gas powered generator that I would like to put in a 4 foot by 4 foot box. Where can I buy the material to line the inside of the box with and the outside? I'm one of these people that likes to do things overkill. So if you please would send me some information on it. I appreciate it

When wearing a tin hat gets an upgrade

What about the hard sided coolers like a Yeti? Then wrap it with a conductive barrier?

Hi Doc, If i had time to undo both battery connections and ground both to earth, ie used jumpers to a metal rod in the ground. Would that sublimate an emp away from the computer in a vehicle? This is assuming there was a forewarning that provided time to accomplish.

You did not give us rookies an exact description of the foil you used. Have been looking can't find exact type of foil and where to buy. Excellent video but really need specifics on foil access and type. Please help

Would layering inside the box provide more protection? Like If I put hard drives/electronics into a small EMP bag and then those into another EMP bag and that into the box? Does that provide extra protection or make a difference if you layered like that?

Were being told that the material must be magnetic not aluminum

From a disaster preparedness standpoint, what are we storing in the box that's so mission critical that we want it to survive an EMP? Honest question. Well done presentation. Your conductive sheet looks like fiber reinforced aluminum radiant barrier?

I bought 3 cases just now under the name Kamera! Thanks so much! Do you know what the average shipping time is? I live in CA, USA

I really wonder if a homemade Faraday cade would work with current technology. Didn't they discover the effect like 50 or 60 years ago when electronics had connections in the mm scale. Now a simple flashlight has microchips with connections in atomic thickness. They should burn indefinitely easier.

Is this any better than a galvanized steel trash can sealed with aluminum tape other than your featured conducted foil's greater thickness?

Instead of using the material, for a smaller box could i just use copper/aluminum conductive tape and tape it all over completely? Would it be the same effect? Thank you

Thank you for a very excellent video. Your test was done at 100 MHZ. So my question is, does this really approximate the frequency of a real EMP? I would also have liked to see you put a smartphone in the box and see if it blocks cellphone signals. And even better, see if it blocks wifi and Bluetooth also.

I think I would just snip those tabs off for the top to simplify things. Not much reason to keep them there unless you're going to hammer them down for storage.

Hello, quick questions: 1. Does the foil need to be exposed or can it be protected on the exterior by a layer of cardboard duct-taped over it? 2. Everything inside the cage needs to be separated from the foil and tape, since contacting the conductive layers would defeat the purpose, correct? If so, would several layers of plastic prevent conduction? 3. Should a ground wire run from the cage to an electrical outlet, using the ground socket hole?

Seems like a round structure using a huge PVC pipe would eliminate a lot of problems leaving only the bottom plastic cover and a fitted wood top.

Doctor, Could there be a synergy between aluminum , barium and strontium being sprayed , as well as 5G , as well as graphene in the injections being pushed ? I know it's a hard question . Thanks.

Also where can one find the corner metal hardware?

What about using thermal paste as a sort of caulk for cracks and crevices? "Thermal paste (also called thermal compound, thermal grease, thermal interface material (TIM), thermal gel, heat paste, heat sink compound, heat sink paste or CPU grease) is a thermally conductive (but usually electrically insulating) chemical compound, which is commonly used as an interface between heat sinks..."

Where can I buy that shielding wrap from? Thank you

How could I vent this if I wanted to put a little frig in?

Doctor, Where did you purchase your barrier material and tape?

'If you double layered the aluminum layer would that give you more shielding?

Would a steel box work for a cage?

Does the kit come with the box or just the covering material?

Awesome video thank you. Where did you find the box? I can make one similar but its a nice pre-built box.

How do folks manage a Faraday system? Two of everything? One laptop in, one out? One cell phone in, one out? Only when they sleep? I have the materials, but I’m constantly using my electronics so they never make it into a diy cage.

Do you thing doing an entire small building would work the same or would it be over kill

Don't you want to protect the bottom?

Thanks for all the great info! I do have a question, I already have 3 inch copper foil tape, would there be any problem using that with conductive barrier you used on this project? I was hoping to save some money and skip the aluminum tape from your site and just get the conductive barrier material for the box I'm making. Thanks again for the info and the help!

Awesome channel and great info. Question though... I'm less concerned with EMP strikes than I am 3 letter agencies and new tech being used to hack and spy on our personal devices. What type of material or fabric do you recommend for absolute privacy and security for a smaller box or wallet size bag for phone, sd cards etc.? Thanks!

Are metal tins that seasonal cookies come in good for a small faraday cage?

Excellent video, as always. I have a question about a large storage box that I am currently using. I have a large, rectangle truck bed box that I am storing my solar panels in, and is made of a heavy plastic material. It is about 5' L x 3' W x 2.5' H. So, the material is not conductive, but I have to cover the exterior with a conductive material to prevent rf intrusion. Besides the material you are using here in this video, can you please recommend an alternative material that I can use that will protect the panels inside, that is cheaper. I'm currently living on a limited income ( ... the result of being downsized) and I can't afford the material you're using, as I require a substantial amount of material. It's been suggested that I use two or three layers of aluminum foil, but I'm concerned about the fragility, as the container is very heavy, and I don't want to inadvertently tear an opening in the foil when moving the container. Also, I have an old style four drawer steel file container that I would like to use for storing additional electronic items ( I'm a ham, and have several different pieces of equipment I'd like to keep safe). Can I line the interior of the steel file container with either spray on truck bed liner, spray on undercarriage rubber coating, or thick pieces of cardboard taped together with gorilla tape, to act as an efficient rf barrier - or possibly incorporate all three products in layers, inside the file cabinet? Time consuming, but I seem to have a lot of time now to take on these necessary precautions to keep my equipment safe from an EMP or CME. Any suggestions or advice would be greatly appreciated.

Wouldn't it have been faster, cleaner and easier to put the conductive barrier on the wood before putting the metal frame in place?

Doesn't thus have to be grounded??

Hello Sir, because of the actual situation, would you say this is also NEMP/HAEP save? Also in therms of the energy load of an bigger bomb. Thank you very much.

Conspicuously omitted is, of course, is the name of the "nice conductive material", "barrier", "high quality material". Is it merely a thick aluminum foil? My guess is that if you wanted us to know, that would have been the first thing you would have mentioned. So, are you planning on selling it and the tape on your website at astronomically high prices??? Thanks, but I built one myself and pray that both mine, yours, and everyone else who has or will ever build one, won't be needing it and that, if we do, they all work perfectly. Thanks, EMPDoctor, and while I do appreciate your videos, most of us can not afford your prices. Still, you have given me ideas that seem like they will work in case of a coronal mass ejection, if not a massive HEMP strike above Kansas.

How much is it for you to build me a box that turns all technology signals off? (I need to sleep in it I'm 5-11 195 lbs)

Saving electronics is great and I do, but-many items will not be saved. In that case unless the power source is disconnected many items will be on fire in a powerful EMP. I would suggest having a plan to deal with those items and where they are located. I have several large metal garbage cans with lids to put small items in that my be smoking or on fire and several fire extinguishers.

The one suggestion is place Rubber old Tires or Rubber mat on Bottom. This will ressistance Electrical Power or Surge. Defetes need for Faraday Box. Plus Surge Protector inside also. Extra Protection. Great Size for those with Cpack and EcoFlo smaller Generator also store portable Solar roll -up Panels.

I wish you weren't doing this on a wooden looking table. I cringe every time you move the box, lol. Otherwise, a great video, thx for the step by step.✅

I think your testing needs improvement. Try putting a phone in it and try calling that phone. Would be more impressive. However. Im not feeling this box would work. I think those tabs are the weak spots on top. Good Luck

Hmmm, What you are using looks like MuMetal, but may look like aluminum foil to casual observers. You should warn your audience NOT to use aluminum foil to block the Magnetic Field from an Electro-Magnetic Pulse (EMP) event, it will only block the Electric Field, a Magnetic Field will pass right through and induce destructive currents in the electronic devices inside. In electronics engineering, magnetic shields are made of MuMetals or Steel to shunt the magnetic fields around something. These are often used around inductive devices like transformers to reduce induced hum in surrounding equipment. To the Audience: Try this: Hold a piece of steel one inch behind a sheet of aluminum and place a strong magnet against the aluminum on the other side and watch the steel be attracted strongly to the magnet though the aluminum. Try the same with a steel plate in place of the aluminum and place the magnet right up against the steel plate. The steel about an inch away on the other side of the plate will not be drawn to the magnet nearly as much. This is why an inch or more of insulation (like cardboard or wood) must be inside to keep the electronic devices away from the steel sides. Using aluminum may work for low EMP pulses, but the "HUGE" EMP pulses created by a special nuclear detonations will not hold up. Remember, EMP bombs are effective from thousands of miles away. You may not hear or feel the event, but if not properly protected, your devices will suddenly stop working (permanently). Look at a Radio Faraday Room you will find in many Radio Frequency (RF) laboratories... they are always made of Steel and the really expensive ones are made of MuMetal. These rooms usually have a fine Steel or Copper Mesh window for breathing air. But a fully closed Faraday Box will offer greater protection from an EMP event. Nothing is absolute, but aluminum is not the way to go for massive EMP events.
