Not a great video. They have the walki talki inside a galvanized metal which is needed to stop radio waves. This video does no justice to the box they built. We still don't know if it works.
instead of cardboard or building a wooden box, why not just use a thick Styrofoam cooler? the lid is already made to seal just like the one you made. also waterproof if not submerged,will float in a flood and if you seal around the opening with waterproof tape, would be completely waterproof. Pet stores and pet fish stores give them away for free if you ask. just get the extra large ones.The Styrofoam boxes are what the aquarium fish are delivered in.I use them to make stray cat shelters,with a piece of overhanging plywood or even cardboard on a contractor bag. those coolers are very useful for many things. I also store tools in them inside the shed and they stay clean and don't rust. Also great to stack up with prepper food. No moisture gets in.
A solar CME is a threat to the power grid and long communication cables. It’s not a threat itself to small digital electronics. The solar threat is not a concern for these devices, especially if a device is not plugged into mains power. A CME only causes the E3 part of an EMP. Definitely worth prepping for its effects, but a faraday cage isn’t needed for that. The nuclear EMP does need it though. Thanks for the video!
If you ever get a chance to go to Black Mountain you should go. I stopped by on the way to the Biltmore last year. It was interesting to see the town. Parts were as I envisioned, and some were completely different. The Pharmacy that John goes to early in the book is so much different than what I had in my mind. - Well worth the trip.
But they used a galvanized metal box to put the walki talki in. It wouldn't make a sound if they didn't put it in the box. So why would it sound of in the box? Lol they need to take the walki talki out that galvanized metal box and do the testing again. We don't know if the box works. We know that the galvanized metal box works only
Thing is you never know when a E.M.P. is coming. My thing is do you keep all your 2 way radios in the Fareday box ? If that’s the case do you have two way radios to use in normal times and use? I have a CB & GMRS mobile radio in my truck , same with my wife’s vehicle. Plus I have a base radio . Not knowing when a E.M.P is going to happen all the electronic equipment I have in use will be ruined. Having a Fareday box won’t help with that so I should have backup radios and other electronic equipment just to keep in the box ?
I have 1 pair of walkie-talkies for everyday use out. 2 pairs inside my box, as well as a spare ham-radio, cellphone, emergency radio, rechargable batteries, battery charger, small solar generator with 2 small panels, old spare laptop, external harddrive with a crapload of e-books on it and some other stuff. Each in a cardboard box wrapped and sealed with heavy-duty foil. All those packed into a large plastic crate that has been wrapped and sealed with the foil as well on inside and outside, then cardboard on the inside again. What is in there is stuff I do not plan on taking out a lot, just once a year to test, then seal everything again.
Since I need to keep mine in a garage, I'd be worried about the EMP wrap getting cut/sliced while moving things around. I'm thinking of lining the inside of a box using this type of material and then adding cardboard/thin paneling to set my items on. Could this ideally work? Thanks
This is a faraday cage for rich people who can afford jackeries and test meters. I also did mine out of a trash can aluminum foil cardboard Duct tape ,and tested a radio on it. If you're on a budget you make do.
We have all the critical items in EMP bags. We have tried to use have redundancies using different types of Faraday bags in hopes that if one solution fails to perform as expected we should be able to have some of all the electronics survive. I just ordered some more EMP cloth to cover another spare solar panel.
@@fullofhope2222 I am not an expert, but it my understanding that this is to be expected. The EMP cloth limits the EMP wave, but does not fully block it. (The cloth that Provident Prepper used in this video is different and blocks more than EMP Cloth.). According to Dr. Bradley, Solar panels are pretty resistant to EMP, but using EMP cloth is not a bad idea. - I do not use EMP cloth to protect other electronics as it only gives 30 db of protection which is not ideal but for items that are not too sensitive to EMG like cars and solar panels, as I understand it, the cloth works well. I hope this helps :) Happy 4th of July!
@@Googlesucks I would like to have something really big for ECOFLOW and panels - Ive roof panels and batteries in house - What are your thoughts on EMP Shield? - Im in Ireland and it expensive with shipping, customs etc
We built a Faraday cage a few years back with a galvanized trash can solidly lined in cardboard, then sealed with aluminum tape. We used 2 cell phones to test it. Put one cell phone inside, seal the cage, then call the cell phone. If you hear it ring or get a "missed call" on that phone, you need more sealing. We wound up also lining the inside of the lid with cardboard, and that did the trick. Cheap and effective.
I just happened to be re-re-re-listening to the audiobook of One Second After as I type, so hows that for synchronicity? I use several steel gift tins (like from chips or cookies), lined with cardboard and taped with duct tape over strips of aluminum foil all the way around the lid for smaller things like radios and a burner pre-paid cell phone and a spare glucose tester. Has to be lined with cardboard (or items kept in cardboard boxes) so nothing conductive touches the metal inside of the tins. Also have a huge galvanized trash can for bigger objects, like my CPAP's 12volt adapter or a spare solar controller, like that. Although I REEEEALLY like the box covered with metal fabric. Way more attractive than cookie tins and trash cans, LOL. Was hoping you'd cover this topic eventually....thanks, guys!
Question please. If we had our gear in these boxes and there was a emp. would the items that were in the protected box be able to work once the emp had happened. I’m asking mainly for cpap machine & gear
@@deniseyonge6973 Denise, the actual CPAP machine itself, if it had been properly shielded/protected, would work just fine after an EMP. What would NOT work, however, is the electrical grid. You'd need a machine that could run off 12 volts (some do have voltage adapters built in, like for car use) and a 12 volt battery plus a way to recharge the battery without the grid, plus all the plugs and wires to hook your machine up to a battery. I'd ask your medical supply place how to run your CPAP from your car. Tell them youre going camping for a week or whatever. Or, like GSD Alpha says above, you could power it with a generator, which would also have to have been shielded from the EMP.
@@gsdalpha1358 Not necessarily. A lot of CPAP machines these days come with built in voltage adapters so they can be powered from a 12 volt battery, with an optional kit But yeah, a generator would also work, provided it too had been protected from the EMP.
You'd probably want to either round all corners or put some other heavy tape over them, like duct tape, to help prevent tears at those points. Also, HVAC duct tape is good for electrical seals, basically metal tape. Not sure if it would be more or less than your tape.
I went to the website to order, but I’m not sure exactly what product it was that you made the faraday box with. Can you tell me exactly which one I’d need to order to make a box like this? Also, how many rolls for a box that size? I have 2 ecoflow generators and the solar panels along with a few other things that I’d need to store/protect. Thank you so much!
8:54 Please test a standard galvanized trash can. That’s what I got and it passes the cellphone test, but most of us can’t spent that kind of money on a tester that we’ll only use a handful of times.
Yes but you need to line the interior with something non conducive. Nothing inside a Faraday cage should touch the conductive shielding. All closures (e.g. top) should make 100% conductive material to conductive material contact. This is often the hardest part to get right.
Trashcans are sort of weirdly shaped too, most are not perfectly cylindrical. If you want to put something large and square/rectangular like a solar generator into it it's not going to fit.
@@stevebishop9468 interesting idea. But I would think you would have to cover the windows and any ports or vents. I don’t know about yours but mine has some pretty open places underneath so isn’t completely sealed up.
To be able to withstand an EMP, and in order to make a proper Faraday cage/box you MUST understand the properties of an EMP. Not understanding the nature of EMP's and making a box that is supposed to protect your sensitive electronics from EMP's that is based on a lack of understanding WILL result in making a faraday box that simply does not work. Anyone with any knowledge of EMP's will tell you that an EMP creates 3 types of waves or pulses. E1, E2 and E3. The E2 and E3 are pulses that "look" like a CME and a lightning strike. The E1 pulse is the pulse that is the real danger. It is this pulse that, without understanding its properties, will be the downfall of faraday cages that are make like yours. I can't go into detail about the E1 pulse, the E2 and E3 pulse. Sufficeth to say that there's a huge difference between them. The radio tester you are using.... that too will not mimic an E1 pulse. For you see, the E1 pulse uses frequencies anywhere from 100Khz to 30GHz.... You are only testing ONE frequency... and I really don't care which frequency that radio is tuned to. You have to be able to prevent frequencies from this huge range and not a single frequency. This is why your microwave does NOT make a good faraday cage. IT only protects you from a certain small range of frequencies and not the entire frequency range of the E1 pulse. You also haven't taken into consideration the amount of surface voltage that will be present on the faraday box if a small yield HEMP hits. A SMALL yield HEMP produces around 50K volts/meter squared. Today's HEMP's produce in excess of 200K volts/meter squared. What does that mean? Anyone that understands EMP's and HEMP's understands that when the gamma particles that are ripped from the upper atmosphere come down to earth, they create the 50Kv/m2, which means that if you have a box, similar to yours, with dimensions that measure 1meter x 1 meter x 1 meter, the surface voltage on that box will be 50,000 volts. Again... this is for the old HEMP's. Today it would be 200,000 volts on the surface of your 1meter box. Depending on the THICKNESS of the material will determine how much of the surface voltage can be present ON THE INSIDE of the box. It is quite necessary to keep a physical barrier or distance from any device inside of the box to any of the 6 sides of the box. For a 50kv/m2 yield HEMP, you are required to keep AT LEAST 1.5" distance away from the surface voltage. It is understood that with a 50kv/m2 surface voltage the electrical voltages "jump" to any device within 1.5" of the surface voltage. The wood may in fact be the right solution here... but you need more than just the 1/2" press-wood, or fiberboard. You really need the 1.5" of separation. In addition, you need to wrap your devices that are placed in the box with heavy duty anti-static material. This is just the beginning of what needs to be done. I find it interesting that many people on RU-vid show their "solution" when the solution really doesn't address the issues that an EMP or HEMP produces. Your "EMP proof" box has many issues with it. I just wanted to let you know.
Generally they have a rubber seal for the top which breaks the Faraday cage. There are also holes in them to allow for air circulation for the cooling mechanism. The interior lining may not be metal even if the outside is but as a starting base it’s a great idea you just have to make sure it is 100% sealed with conductive material. Cover all holes (air circulation, power cord, drain, piping, etc) and work up some way to seal the top (note, exterior finish (paint) may disrupt connectivity.
Just put your cell phone in the Faraday Cage. If it is sealed, the phone will run the power down to next to nothing in a very short time, as the phone will continually be searching for a cell tower to ping off of. A simple 'cage' is a large dog food bad that is lined with metalic sheeting.
I use 45 gal steel drums with pinch rings, lined with cardboard. Change gasket out with an EMP model gasket. Also have some 5 gallon pal go models for small electronics like communications. One small rip in that fabric and the box is compromised.
I’ve read all three of the books, one second after, one year after and the final day. Question, aren’t the solar panels for charging the solar generators also susceptible to electromagnetic pulse?
The diode rectifier for reverse polarity on the solar panel can be affected. They are typically rated at 400v - if the induced reverse voltage is above that threshold there is possibilty that the diode will short open permanently.
I was under the impression that electronics was protected from an EMP event if just turned off. Is this correct? Should I store my spare electronics in the EMC safety box? Thanks for the video….
Being off doesn't stop strong magnetic current from frying electronic components. Your device doesn't attract magnetism by being turned on. An EMP or strong CME penetrates the chips themselves.
Yes but it will only protect through limited frequencies of EMP. Switching out the front plate (the screen with holes in it) and covering all other holes will greatly enhance the range of frequencies protected against.
Awwwww …. I have 4 Jackary units. I need to get busy. I’m a disabled female so it’s gonna take at least 4 faradays because they are located in different “zones.”
Btw - I forgot to mention… Some types of copper conductive foil tape comes with CONDUCTIVE ADHESIVE! It sure beats soldering bridging braid or other methods of achieving true multi surface equipotential. Motorola used to carry it for their repair depots and other sources. The price wasn’t really too high and they also had a variety of widths available. (1/8” / 1/4” /1/2” 3/4” 1” / 2” / 3”) Great video as always. Thanks!
--- I would have liked to see you try other devices, like CB. Ham, stander radios, short wave radios, Wi-Fi and cell phones. I would like to have seen you compare this to other homemade faraday cages. Metal drums, steal trash can, aluminum can.
Build a faraday cage- use it to stored electronics and back up equipment and electronic components. I keep 3 cans just for back ups electronic devices, batteries and power generating systems. Plus i will keepbextra wide variety of electronic components- resistors, capcitors, computer chips plus "SD cards with lots of stored data and computer programs. I can repair my stuff for free and help out others. 1,000 in componets being protected. As a profitable business.😅 😅😅 Just like seeds and canned food in jars to cover over 2 year supply for myself. I live alone. I can grow extra food to sell. I also keep containers to store 500 gallons of water or pull it from the ground.😮
You needs some BASE to your sound. You sound is too high. Don't you do any kind of sound check and no my phone sound is fine. Check your output, too elevated. Thanks, Robert.....
Its not all going to be protected. Even minimum. You still have. Some electronic protection Faraday cages don't have to be. Perfect A roll of chicken wire. Will protect you car
The more powerful the EMP the more powerful the faraday cage you would need to ground the electric field, no? So just because your cell phone doesn't ring ... does that really mean it's going to be enough to withstand an military grade emp or carrington event?
I wonder if they make car overs made of emp material to protect your vehicle so you can drive it in case. And make one for inside your home to store cell phones or any electronic devices or equipment if need be.
It would have been a nice comparison point of your effective invention if you had jarred the lid or just not snugged it and called the 2-way to see what happens.
It would still be an INVALID test as it only tests a single frequency. The military tests against the frequency range that an E1 pulse produces... and that should be the standard, not the guy on RU-vid that is only testing a single frequency. THERE ARE SO MANY HOLES IN THIS PRESENTATION I CAN'T BEGIN TO START!!
I've heard varying things about the effect of such an event. One guy who claimed to do research in that area stated computers would crash, but could be rebooted, cars stall, but restarted, etc. - no actual damage to the gear.
It would depend on how much power is being channeled in the air. If it's enough to send a current through your computer that would fry your chip...they aren't turning back on. If it's meant as an attack then it is going to be strong enough to blow out industrial transformers and therefore should easily blow out every delicate computer you've got in your home.
The 2020s don't have new DIY instructional VHS's anymore, but if they did..... this would be one of them. Even has the scripted kid. In all seriousness though this is an impressive box because of it's size and the fact you tested it well.
I’m going to play devil’s advocate for just a moment. Is the metal box the tester is in adding to the shielding? What about a walkie without casing inside the box? I used to build SCIFs back in the 80’s and early 90’s.
To prouve better your point I would have tested it with the lid open to show the beep for the test device and then would have tested it with the lid closed. It would have prouved how efficient it is. Also I would have put an antenna on the outside radio. Good video
Agreed the feedback loop is not a true test. He should have an antenna on the outside radio and the inside set at zero attention to see if it blocks the signal. Then speak or press the SOS button and for a check of the Inside radio. Overall the tester seems like snake oil to me. I have worked with RF as a satellite operations engineer for over 20 years and hold my General class ham license. Not saying the box doesn’t work but that the test method seems flawed.
Exactly@@ccrews0612 The E1 pulse produces a HUGE frequency range... down past 100kHz and up past 30GHz!! People simply do not understand EMP's or HEMP's!!
Radiant barrier works. Wrap yr card board boxes with radiant barrier just like u wrap Christmas presents. I got 1000 sf (4’x250’) for $110 usd. Passes the fm radio test with no issues. This amt let’s u cover just abt anything u can think of.
Sorry for the negative but you did the test wrong. Take it out the galvanized box and put the walki talki directly inside the box. Only then will u know if it works.
A fariday cave will not help unless it was a detonation e.m.p. in the case of a solar flare your cage will draw energy and fry. Place your stuff in a thick plastic container. Tesla would agree.
You should build a Faraday box for your car battery and alternator and the brain in your vehicle just incase your driving or need to drive to get some were
QUESTION,,?? and I do t mean to appear umm,stupid,,but if the grid goes down and everything gets fried by emp,,,won't everything else just CRASH?? Like, nothing electronic will work???
Im a Ham Radio Operator & have lots of expensive Radio equipment & I was thinking of bunging it all in my chest freezer as soon as War is declared as the metal grounded cabernet should offer some protection. As for my larger items like a 50 inch plasma TV & several smallers sets I thought I could wrap in aluminium foil & ground it to the water pipes on the central heating radiators. Antennas to TV, broadcast radio receivers should be disconnected as even a weaker EMP would damage the receivers front end at least. A microwave oven should offer protections to Ones electronics. It's knowing when a EMP attack is coming as we dont want to be deprived of our gadgets by storing them in an EMP box & just waiting for it to happen.
I expect that the EMP event will happen without notice. Maybe if you have your ear to the ground and can read between the lines, you might have 5 minutes notice.
@@ToiletTrainingTales True, but I bought 3 trash cans & have devices packed away in cardboard lined trash cans & larger items any metal insulated & wrapped in foil.
You need to save an older cell phone and leave in the box. Since most of us live with our phones, having a "burner" phone will be important. We purchased a small shortwave and transistor radio to put in our cage. Having a ham radio is also a good idea. A means to communicate and hear info may be what saves your life.
Thank you, Kurt. I have asked several different people in other groups and you are the only one to answer me. I was confused about how to protect my LG if shtf. I can't. I need to get an older phone and store it. But I need to have it activated first.
Another thing to consider- if shtf happens, odds are there won't be cell service. A cell phone will likely only serve as a storage device for addresses, recipes, photos etc. I doubt you will be able to communicate with them. But who knows, maybe there will be cell service. Odds are only ham radios will be able to talk and receive. There is so much unknown that it is impossible to prepare for every scenario.
@@kurtmunson5539 True, which is why I have a spare ham-radio as well as 2 sets of 2 way-radio's in there, plus an emergency radio with handcrank. Old cellphone, old spare laptop and external drive with e-books recipes, addresses and more as a backup, though I keep most of that as hardcopy in paper too.
