A better stylish smartphone Faraday Box

- 9 months ago, I made this video: • Make your own stylish ...
Since then, I've learned a ton more about Faraday cages, and experimented a lot to make an even BETTER box.
It turns out that my original box was only so-so at blocking Bluetooth. My original testing of Bluetooth blocking was, shall we say, not very thorough. My primary focus was blocking cell network signals.
I also mistakenly assumed that if Bluetooth was blocked, WiFi at 2.4 GHz would also be blocked. Nope! WiFi is much harder to block due to the higher signal strength (among other things).
I'm fired!
To make matters worse, we're still learning about how Faraday cages actually work (people.maths.o...!
And so, I give you: Stylish Smartphone Faraday Box: Mark II
Aaand, I'm rehired!
One thing to keep in mind is that for some people, a simple cookie tin or wrapping the phone in aluminum foil will do. But - and this is a BIG but - it really depends.
What phone? What signal strengths are we talking about? How close is the transmitter you're connecting to? What WiFi band are you using? How good are the seals on your box (conductivity-wise)?
Faraday cages never actually "block" signals - they simply attenuate (or weaken) those signals. Thus, what works for one person may not work for another. This is why Faraday bag manufacturers report numbers like "80dB of attenuation" or "100dB attenuation!".
You may even find that you can buy a $99 Faraday bag, stick your phone inside, and if you're standing too close to whatever antenna, oops! It doesn't block the signal. It's a tricky business, and it's a lot more complicated than just: foil = works.
So, you're gonna have to test things for yourself! This box was VERY thoroughly tested, but with my Nexus 5X phone, my Bluetooth accessories, and the very good 2.4 GHz Intel WiFi in my high-end laptop.
Also, you do NOT need to ground a Faraday cage/box. I did all my testing for this new box twice: with and without ground. The ground made no difference. Usually, pro Faraday cages are grounded for reasons other than increased shielding, because grounding is not necessary. The redistribution of electrical charge in the metal of the Faraday cage is what's important.
Finally, the equipment needed to thoroughly and properly test a Faraday cage is beyond most of our budgets, so the simple alternative is to test, test, test for your specific gizmos and situation!

Your two videos were super helpful. I just made a 'faraday pouch' for my phone and it is thanks to you that it all went perfectly.
I made two pouches - one smaller to fit in the other. Tyvek envelope wrapped in copper tape wrapped in gaffers tape.
When the phone is in both pouches there is no bluetooth, wifi, or cellular. Thanks for taking the time to share with us!
Glad I could help!
I've been wasting my time wearing tin foil hats, now I wear copper foil hats. :)
lol hehe
In "Electromagnetic Compatibility" by Henry Ott, he suggests that a basic metal paint can is pretty close to an ideal shield. In theory, steel is preferable because it is more lossy at high frequencies, and the can forms a very tight seal. The perimeter of a hole matters more than the area. Even an extremely narrow insulating slit could form essentially a "slot antenna".
With that said, putting something that is foremost a radio transceiver in a Faraday cage seems kind of silly.
If you're worried about eavesdropping, the spies are likely caching audio data to the device's internal storage anyway, in case of bad reception. Otherwise the ebil terrorists could foil them by going for a stroll in the park. I'd think it would be more important to make the box soundproof.
Edit: forgot to mention, I think I have encountered copper tape with non-conductive adhesive. It might have been the sort sold for repelling slugs.
I know firsthand how difficult it can be. I started with a mylar chip bag-- didn't work at all. Then layered faraday fabic inside the bag, hot-glued to hold it in-- meh.
Then a ziploc bag with more faraday fabric-- ok, becoming effective.
Only drawback is that I originally wanted to just drop my phone in, easy peasy.
It's more complicated than it looks!
Yeah, and it also depends on the phone and where it's used. If the phone has poor reception, the cage will work better - but not for another phone with better reception. If you test it in an area with poor coverage, it may work - but stick it in the middle of a city where there are 8 million towers and excellent cell coverage, and forget it!
24 oz Monster drink can with the top & bottom cut off, 1 end folded over with aluminum tape, spring clip other end. Done.
Aluminum has that thin oxidation layer. I'd try copper braid in the lid to box seal.
Oh dear - good point!!!
Blocks emp too!
There are a number of things you can put your phone in when not using....even a microwave oven you are not using....or a metal cookie can...or a few chip bags with metal coating/mylar...very easy: jut fold the bags until the phone is protected on all sides. Works well.
MY BIGGER CONCERN IS TO HAVE SOME SORT OF WAY TO PROTECT THE PHONE FROM BEING HACKED WHILE I AM USING IT!!!! PLEASE HELP!!!!
From the novel “Catch 22”... “just because you are paranoid, doesn’t mean that they aren’t out to get you”
I used to say that all the time and not sure where I got it from.
Never read the book, as far as I recall.
@@Freakazoid12345 Nirvana? I used to say this too, but just learned it's originally from this book. Kurt says it during the bridge of Territorial Pissings.
@@3l1io7t Nirvana is from this book?
@@Freakazoid12345 No, sorry if I was unclear. I meant the saying is in a Nirvana song called "Territorial Pissings". I thought maybe that was the alternate source of the quote for both of us.
I build MRI rooms and there is a science to making rf (radio frequency)proof rooms. You need several components . A outer metal shell. A inner metal shell. Both shells must be isolated from each other. All gaps must be tight or have a copper mesh or wool to make the connection in the shell tight. Both shells must have a independant ground connection . They use this in MRI. Corporate conference rooms and in Embassies worldwide.
Thank you Whirl Wind : That was the answer i was looking for.
You are welcome , good luck with your project.
Thats really good to know
Any suggestions on how to run the ground from the inner layer through the outer layer?
So you saying this wont work?
Despite the sarcastic and spiteful comments made, I found this video to be highly informative and educational. People forget we are all mirrors of each other. Great video.
Glad you found it useful!
That's strange. I never heard him make one spiteful comment or picked up on any sarcasm. I think peoples projections become the reflections that they see in the mirror. :)
L Mc Yes :) It's a starting point. It's a fun challenge.
Thank you so much for this comment. We need more of this online.
I think the commentor meant, "self effacing, or modest". Scotties humour is excellent
"So after i got this box, i thought, well, you know, heck i can turn it into a Faraday cage, how cool would that be? Because i'm a nerd, right?"
Hahahaha. Totally. You owned your mistake, you made it better, and it got you a new subscriber.
Very well done! But, it's kinda like burying your gun. What good is it if you can't use it? I'd like to put a whole room inside a faraday box. That's a lot of copper foil!
you can get shielding paint from Germany.
@Ashley Razz how are you going to access it then?
Use cables and turn wifi off on the router.
I find it hard to comprehend as to why somebody hasn't produced a portable metal case like an extruded metal cigar case in which the lid comes off the bottom half, your cellphone slides in and the top slides back on. Surely a rocket scientist would have enough incentives to design, build and market something to block cellphone, wifi and bluetooth signals ?
Just build a Faraday cage inside your entire house . No joke... You may or may not
know this . If you have Wifi in your house you can be watched through your walls.
I predict that many future homes will be built with the intention of being a Farady Cage...
Maybe the Drywall will be already impregnated with blocking abilities and all of the Drywall
Will have contact points to shield the home...
Guitarist and guitar tinkerer here. So we use that tape as well as cavity paint for RF shielding. Theres a method to apply the tape where every strip you lay down, you dog ear one corner over to the previous strip of tape. For a wood box, the cavity rf shielding paint would probably be better. Its what youll find if you open up a decent guitar. Its black in color. Both are used to mitigate what is called "60 cycle hum" most commonly found in single coil pickups. You get that 50 or 60 cycle hum from flourescent lights, electrical wiring etc. Hope that helps.
Thanks for the info!
Just done the shielding on my strat - I was thinking the same thing!
In eng.school the 50 Hz interference from the room lights always had to be accounted for. It's just a consequence of having a 50 Hz grid. The lights look constant but they're just flickering at a rate that we can't see. Can be 60 depending on where you live.
I was going to leave the same comment until I read yours.. I just built a Strat style guitar and shielded the cavities, important part is the shielding needs to be grounded..definitely notice the difference of the amp humming..60 hz
Perhaps, delete the original video that has incorrect information.
I love the honesty & love even more the will to investigate the mistake & solve the issue! Thanks for the pitfalls & pointers!
Try an old camera film bags they reflect xrays from airport's terminal.
Hey it's All good, And it's well worth it to watch both videos, I followed the prompt from the first video to take me to this one. 💆your no idiot, as you happen to mention it as a passing comment, 🍸All this presentation took discovery and experimentation. And was a treat to watch, Yes you're amazing, And helpful on uncommon techy like stuff too, you are helping to inform all of us who watch these videos, to give it a go ourselves, and to test it out, to see and do what works best for each of us, in different scenarios, situations,and locations, oh and other continents, Thanks Scottie. 🌟👍
This is awesome info. More important than ever, when considering what governments are planning with the "contact tracing" apps. We all know it's not just about our health. This summer, Google and Apple will already add them into the OS and the next update for our cell phones will give us the app/service without anyone downloading it. I don't want to necessarily have to leave my phone at home every time I leave the house, but it is my first option until I have a working Faraday Cage/Box, whatever available for it. This government overreach has to be stopped, especially because it will be implemented globally. We are already giving our privacy away each day with our cell phones. This info is very valuable to stop this. Thank you so much.
Scottie, you're right that there's a lot of disinformation on the internet concerning building a Faraday cage. I'd read that you could take a metal box and line it with cardboard.
I took an old metal lunchbox and glued in cardboard from file folders. However, where the lid fits down over the bottom there's paint on the outside of the bottom which I didn't remove. The cell signal still got through.
Then I wrapped my phone in one layer aluminum foil and put it in the box. The cell signal still got through.
I also tried putting my phone in a stainless steel refrigerator, but the cell signal again got through.
Through my experimentation I have learned that it's MUCH easier to block the signal of a car keyfob than the RF cellphone signals. And that the range of frequencies for cellphones is 600 MHZ to 2500 MHZ.
Thanks for this very informative video. Now I'm not stumbling around in the dark!
I'm also now wondering if those Faraday bags you can buy really work to block cellphone signals, Bluetooth and wifi?
Thank you for being honest!
Use Coffee bags. They have been used for decades to coat the inside of bags to steal stuff from shops ;D I bet most androids ramp up the signal power if the signal is weak..
An improvement that I would suggest on the Faraday bag, is that you turn the plastic bag inside out and then apply the copper tape that way instead. Just a thought.
good idea ,and then the outside .double farraday cage?
Outstanding video! Learned much! Thanks for making it!!
Would a box made of copper work?
You can protect an emergency radio from EMP by wrapping it in aluminum foil, then a big blob of bubble wrap and then wrap the entire thing in aluminum foil again. Just store it away without batteries and it will survive the disaster.
Thank you so much I learned quite a bit just now... will be making my own box/pouch a.s.a.p. no more office trying to micro manage me on the clock lol... about to ghost them everyday 😊
Go 5 minutes in to see the NEW faraday copper tape box lining! The first 5 min. he talks about how his OLD faraday box failed-who cares? At 11:54 min. in-see the additional upgrade for total signal blocking! Now that's GOOD!
wouldn't it be better to glue the phone on the shed wall and check it when you mow the lawn?
No
I would not trust a hammer to destroy the info in a cell phone. I would prefer to do it like Terminator 2 where the Terminator is lowered into molten metal. What did Hillary use? Was it both BleachBit & hammer?
@ScottiesTech.Info your intention was good and logical, but as a verified targeted person here's a few thoughts. Firstly, I've had a Cornet meter for years and have many videos documenting how much I was being pulsed. I have a networking degree and started using my education to start ringing the alarm years ago on FB... bad idea! Anyway, be careful of putting and device in a complete faraday cage without putting it on airplaine mode of just off. They'll sent out constant broadcasts for a connection to the cell towers which may bounce back and destroy your phone, etc. I KNOW BECAUSE I DESTROYED 2 OF MY ROUTERS WITH A GROUNDED ALUM FOIL CAGE I MADE. Also even when a phone is protected and I measure the pollution, I pick up pulses from other sources like neighbors routers, BT devices I use, the smart meter, certain places along my home electric wiring system and a lot more. It's even worse when I'm driving around and every biz and tower is broacasting. When driving meter is constantly 10X the red danger level. Really no great solutions, but personally I only use ethernet cables in home and no WI-FI is active on my router, phones stay at the front door with keys and I constantly measure with a meter
You know cars are a form of Faraday cage, right? No wonder the meter's readings are much higher. Something about signal strength increases due to being on the move, and it thus being more difficult to pick up a signal. Then there's something I read about cars being protected against lightning and that having something to do with it though I don't remember the specifics. I think I read it somewhere on Lloyd Burrell's site, electricsense.
Tom Visser i get your logic, but although cars have their own ground its no going to true earth ground so no faraday car. as for the high readings, one i put my phones in my port. faraday basket i made the readings were safe. what ive noticed is the way cells try to ping and find wifi to offload data traffic from their cell towers causes non stop burts that are off the meters limit
"I KNOW BECAUSE I DESTROYED 2 OF MY ROUTERS WITH A GROUNDED ALUM FOIL CAGE I MADE. "
If you put a faraday cage around a transmitting device, the signal reflects back internally. So you cooked the routers in their own emissions.
JL Moody any way I can bock car tracks?
o.k. 2.4 GHz from 4G is one thing but how does it hold up against 60GHz from 5G? Update? Thanks
What is the reason that by definition a Faraday cage is suppose to stop all signals and here is proof that it does not totally work ????
Could you made one for a a wallet? To block NFT?
Thank you :)
NFC fucking NFC
Maronidis KOstas Dont be mean.
@@yourworstnightmare1488 near field transmission or communication. whatevs, man.
Lead works perfectly, you get it as paint, foil and tape. The tape is used for weighing down golfclubs, the adhesive foil is used by flyfishers and the paint you get in most hobbystores. And its REALLY cheap
Strange.... After watching this vid I find myself craving a Reeses Peanut butter cup. Like-a-said.... Strange. :0)
Peanuts contain high amounts of copper. According to the USDA, 100 g raw peanuts contain 1.144 mg copper which is more than the recommended daily amount. I once read something like the body knowing what it wants and you craving the nutrients you need as a result.
So now you know an even simpler way to cut off any signals. Just fill a box or something with peanut butter and shove your phone in(kidding, of course).
The colors brown brick and peanut butter!
Nice stuff man, I like your videos. One improvement I thought of during this (second) video: As you are looking down you can still see a lot of wood along the mating edges. Why not continue the lip-wrap all the way along the edges of the lips. If cosmetics are not an issue then keep going: wrap it around the outside too until you run out of copper-sheet.
Im a dummy. Still not understanding what to do
Me too
Why cant you just use a metal container made of tin or aluminium?
“Everyone’s got a piece of foam laying around” .... *rips open throw pillow*
Sorry but why use a faraday cage/box??? Unless you plan on destroying your device, they will continue to track you when you decide to remove from the faraday.
I always thought a Faraday cage had to have an earth (ground) connection to drain all the induced e.m.f off?? Would your box (or a bag) be more effective with a ground connection? Thanks
How can we add a ground connection and still seal it 100%? Is it a matter of adding dirt inside the bags?
Hi Ellen. A "ground connection" in this instances refers to an electrical earth or "ground" which, for our purposes, doesn't necessarily involve physical earth or dirt. In this instance connecting a wire to the metal of the Farady cage then the other end to a good electrical earth is all that is required. For instance connecting the other end of the wire to a good, clean, cold water pipe should suffice. Scrape the pipe until you can see shiny clean bare metal then trap the bared end of the earth wire against it using, for instance, a hose clip. Make sure that the wire makes good, tight contact against the metal of the water pipe. Better still connect to the EARTH terminal only of a three pin mains supply plug but don't even attempt to mess with mains electricity unless you're 100% confident; A direct shock from the mains is even more lethal than exposure to 5G!! ;0) Hope this helps; if you need any more assistance please message back. Good luck and good health to you! Russell
@@russputin6294 Would the earth on a car work?
@@Isaac-YLYL Theoretically, it should. In effect a car is one big Faraday cage; this is why the car radio aerial has to be outside the vehicle or "visible" to the broadcast signal through glazing or similar. In fact, back in the day when car radio aerials were telescopic rods mounted on the wing they were always earthed to the metalwork and had a shielded cable, earthed at the socket, to prevent interference, I hope this helps and have a great day my friend
Sorry; just as an afterthought; this would only apply to metal bodied cars. Fiberglass bodies (now rare but, for instance, the old Reliant Robin three-wheelers) and carbon-fiber panels present a whole set of different problems! Thanks again for your interest
Can the faraday cage be 'grounded' by attaching a conductor to a charged dc battery negative pole only? Acting as a ground while still allowing the whole container to be mobile, carried from place to place?
No, it would have to be ground - as in copper rod in the Earth ground. If you attach it to the - pole of a battery, that's only negative relative to the + pole of the battery.
Instructions start at 3:08
Hi! You say you used packing tape around the copper in the bag. Do you mean that you took a big piece of copper foil and put tape all over it and then folded it into the bag, for the phone to slip into, inside the folded copper? Thanks! 😍😍😍
I put the copper tape all over the outside of a plastic sandwich bag. Then I covered the copper tape with packing tape.
metal cookie box and cardboard lining.
enjoy
Yep
Neat! Like a cookie tin with a fitted lid (might have to sand the paint/print off the contact edge for maximum conductivity) and then put it in another popcorn tin. Cool idea!
Two cookie tins will cover it for sure
Yeah I tested it and it doesnt leak phone calls
Scotty you know who you look like? Guy Fawkes; you look like the Guy Fawkes mask from V for Vendetta! Awesome video.
Faraday boxes don’t work. You need to make a faranight box.
Thats the Gold Sarphofagus from Egypt? Or lead one?
Switch to the Faraomnitimeandspace box, that works just fine in any point of spacetime regardless the necessity of having a local sun to indicate/distinguish day/night periods :P
@Maddie Loves Jesus talk to your company that have placed it ther and say to them that you would like them taken away becourse off health hazard and fire hazard look it up under youtube danger, health hazard ect for smart meters ;-)
Can you please recommend a cheap meter to measure electric, BT, WiFi and 4G, 5G please,?
My friend Amber almost died from a cell tower that got installed close to her home and since then she’s been very into this stuff. She referred me to this meter which currently is priced at $148.80 on amazon. 6 months ago when she sent it to me it was $124. The price and demand keeps going up bc I people are getting educated. She said this meter has just as good RF detection as $500-$1,000 meters she’s owned. It’s an absolute steal for its value. Measures EMF, magnetic fields and RFs that cell towers shoot off. Search “gq emf 390 meter” in Amazon and it should pop up.
You should delete or edit the other video or make a new video. That way people aren't getting the wrong info.
if we cant get these dmn smartmeter things out..how can we cover up those smartmeters...and all of it...thanks so much for trying! bless you and i am grateful ANYONE wants to help!
how about a lead box, it worked for superman :0)
Too heavy for my purse.
What happens with 5ghz? It gets blocked or not?
5 GHz WiFi is blocked - at least from my particular WiFi router, which does 2.4 and 5GHz.
Great improvement- I didn't know they had copper tape- cool!
Why didn't you take the original video down?
Scottie, Thank you so much for this information! Would you please give some input on if crystals, specifically Shungite and black tourmaline are testing positive for proving to block Wi-Fi?
Hey Scottie, i really enjoyed the video and much respect for the time and effort you put into it. I don't quite get why people are soley obsessed with blocking their phones signal. If i remember the snowden files correctly besides harvesting all your (meta)data government actors are using the device as a bug you always keep close. Shouldn't the focus be more on having a soundproof box for the phone then in order to keep things private?
Both would be ideal. With some kind of malware, the phone could turn itself on, record while inside the box, and then transmit the data next time it's connected to the network. Of course, the box I used is actually pretty good at muffling the sound, so it's better than nothing. Ideally, I'd just yank the battery out, but alas... nonremovable batteries are annoying. Mostly I just wanted to see if I could make a good Faraday cage for a phone. I have a friend who keeps his phone in an old cookie tin, and I suspected it wouldn't be enough (it wasn't).
One thought is to remove your cameras and microphone from the phone and use Bluetooth headset when you need to make calls etc. and don’t use your phone as a camera. That is what Snowden does.
@@ScottiesTech Couldn't that work with your smart tv's too? What about other smart equipment like your laptop, tablet or appliances? I myself prefer dumb appliances but they are harder and harder to buy.
Check Out Mission Darkness Faraday Bags
What about a carry faraday cage for your Android phone?
What I've found is if you use aluminum, Cobalt and Copper layers you can block quite a bit more. I line the inside of my phone cases with this combination to stop the side of my phone that is against my body from radiating into my body. The amount of WIFI routers my phone finds goes from ALL to basically what is in my own house only with this setup. I imagine that using a similar combination of layers in the box might fare better than just straight copper tape. MAKE SURE THE ADHESIVE IS CONDUCTIVE if you try this setup.
I was reading an article that talked about using magnets as well.
I noticed that when I turn my phones wifi off at home, to go to class, come back home, and turn the wifi back on it'll show my schools wifi in the list of nearby signals before refreshing. I guess my phone is always scanning for wifi even though it's wifi is "off"
Yup. "Off" isn't really off these days...
It’s doing that based on your location. It remembers what WiFi was in the same location before.
summary: copper foil lined box. make a flexible, perhaps foam-like lid so as to block any little gaps. use plexiglass or similar to protect the foil from damage by the phone moving around in it.
make the box double-layered. layers must be electrically insulated from each other. A foil lined ziplock bag works as the second layer.
5G untested.
CIA transceiver untested.
What about Tesla scalar wave transmitter goes right thru the best solid metal boxes look it up
dlhvac1 EMP it ! 😎
So now I need to make a copper hat to replace my foil hat? 🤦♀️ 👑 💫
If you have a house can just put it way out in the yard in a zip lock for the night?
Scottie, I Love your channel and want you to know that. Even though this vid is several months old I am only seeing it now and have a worthwhile comment to make, so here goes .... Most everyone has an old microwave oven and many do not use them these days, due to the fact they blow up the cells of the foods, rendering them un-recognizable to our body and end up as clumps of cellulite, clinging to the tissues in our body and offering next to no nutrition at all. Many years ago I would boil water in a microwave, but then I realized that water also has cells and has memory, soooo I now only use my old, hand dialed timer, (not digital buttons, in other words) as a Faraday Cage. People can cut the cord off or simply un-plug and make the end of the cord unavailable to anyone and Wah Lah ! A place to store all things techie. That being said, all microwaves are not created equal and some may leak a bit, so checking it with an emf meter is suggested. Hope this helps someone. : )
Dear Scottie, what an incredibly useful video, that lets me have peace of mind, should I ever need to shield my devices. I learned how to both improvise and TEST my Faraday cage. Oh and after Googling the man himself, he is a very interesting character, who was featured on the UK 20 pound note. You are educational too!
What about incorporating one of those bags that electronic devices are sent in. I believe they're called 'EMP Shield Faraday Cage ESD Bags'?
Okay.. so I wanted to make something quick and easy to place between my cell phone and my body to maybe "deflect" the signal elsewhere while watching vids and movies.
I covered a piece of cardboard front and back with a double layer of heavy duty foil, then bent the top towards the viewing portion of my phone.
Do you think this will bounce some of the signal away from my body?
I realise that it wouldn't block it all because I am still looking at the screen, tho further away than I usually veiw.
Also... will you show an image of what the signal looks like, is it a straight beam with a measurable height and width..or does it have spread to it like
Illustrations of the sun's ray's we often see..or is it something else ?
I'm not a tech person, I'm a retired nurse with a neverending curiosity and need to tinker.
Thanks 🌷
The beam spreads, but your "armor" should reflect quite a bit of the signal. Just make sure the foil is not touching any bare skin.
@@ScottiesTech thank you for answering my question 🌷
Hey Scott, Amazing work man! I did two things with regular tinfoil.
First: I covered each interior side with 4 layers of regular tinfoil.
Second, With some folding skills and rgular tape I did a little faraday pouch.
Of course, you have to be careful with the gaps, even a tiny slit can create a signal leak. Both work great individually and I was also kind of worried about WIFI. However, When I used the pouch and then put it inside the box, it worked wonders. Bluetooth, Wifi and Cellular are completely rendered useless. Combination of amount of tinfoil, proper sealing and inspiration makes a perfect combination. Thank you for the inspiration and information Scott! With 5G at the door, I think a Third installment of this faraday box series is in order
Hi Scotty! I think your Box may work without a copper cushon if you fold the copper foil around the corners where the lid comes down without pasting them on. The foil will stand up a bit & press against the foil on the lid. Of course it only works if you don't winkle the foil. It is probably better to use ordinary thin copper foil that has no stickie side. Then you can fold it like a sheet of paper & have straight corners.
A small step for a nerd, but a great leap for a beginner nerd! :D Thanks man, now I know my perfect Christmas gift :))
Hey man! Make another video and do a screen recording on the smartphone you put inside the farraday box while it's inside.
I respect your detailed commentary. Looks like I could make one based on "boxes in boxes" if I had the time. I remember my old company going to the desert to do EMI testing. It wa$ definitely expen$ive.
O,' my gosh what are you doing? If I could fly out to you I would love to help you, because you're just messing everything up. But I love you anyway, your a really good guy.
Can you take a couple of inches of the woven/braided desoldering copper wire "tape" and solder each end to the top and bottom of your copper box to bond the top and bottom together?
It's better if the top and bottom edges are fully touching all the way around. Any gaps, and you get "leaks".
Now what if you're preparing for an EMP event? How would your bag/box work? Is there any way to prepare for a CME or EMP?
Beautiful idea with the bag! I'll try this with a double coated bag only (no box). Wonderful information! There might be an issue in the wifi experiment. As i understood you used your phone as the wifi hotspot? If so, it needs both the cell signal and the wifi signal to transmit. If it you don't receive wifi on the computer it's not necessarily blocking the wifi, it might be blocking the cell signal only or wifi only or both... (Or i missed something). Could you link to the studies you mention on 5g and faraday cages? Thanks!
Dude, don’t let the comments get you so worked up. Some people live to ruin other people’s day. Some people just like to watch others get worked up. Some people even comment “doesn’t work” without even trying whatever it is. Because some people are assholes. That’s just gonna be true. Some people are assholes, but you don’t need to be an asshole too. That’s my motto.
Obviously because the reverse EM field inside Faraday cage wont be as strong because no metal is ideal or superconductive. And i assume the other things in box construction also contribute to resistance.
Solution: two boxes. A shielded smaller box within a shielded bigger box.
Edit: Just watched the full video. Bingo. You need double protection to block off all signals completely.
Dude, Imo, ur missing the point and "majoring in the minors". Simply put, if u want to render the microfone useless on ur various pieces of equipment, forget about blocking the wireless signal....instead block the sound. Build a sound proof box to put your equipment in. There.....mystery solved.
Okay wouldn’t lead based paint help block the signal as well?
Basically you paint all the surfaces on the inside with lead paint, cover with copper tape, create the seal, paint the bag in lead paint, wrap with copper tape, and then insert.
A good upgrade to this would be to create a magnetic charger base and properly seal the power cord insert that way it can charge inside the faraday cage and still block signal (the seal for this would need some work but I think it’s doable).
How in the fuck did he get a real lot of views, it takes him a minute per sentence as he goes around and around EVERY THING HE SPEAKS OF, WELL, GOOD BYE scottie boy ,
If you want to know if you Faraday cage works well put the cell phone in to Faraday cage. Put the AM radio on 5:30 a.m. or lower. if you hear the radiation or the pings from about 4 in away you don't got enough aluminum wrap.
Hey Scottie.
I am not supposed to say this, but a very good friend of mine who works with the CIA told me that, ever since your first video about a Faraday Box, there's this strange car parked near your house every day. Maybe you should go over and offer them a coffee or so. :)
Now I've to go, because there's someone at the door.
Best video on Faraday Cages I've seen and I've looked at a lot. Thank you :)
I'm not sure.....But .... I have heard that silver...... blocks the signal...! ???
Great Faraday cage (double). Curious, if you were to ground the first cage, would you have better results. One could be an electrical ground (which can be noisy), or a grounded rod into the earth. Just curious, otherwise great video.
Yeah, that's the trick with grounding... It's very easy to introduce noise and even couple signals into the Faraday cage unless you do it correctly. Without a ground at all, it should work perfectly - but then you might need a 2nd layer for full signal blocking.
I watched these two video's of yours and now have conspiracy videos showing up in my suggested videos, thanks you tube.
Maybe you should watch them? Some of it is very thought provoking. A lot of bull, too.
you know the copper tape makes a stylish yet practical tin foil hat! mines a fedora. soo want a fez next though.
Conspiracy is a cℹ️a term
Look into it many conspiracies are now proven FACTS

it's not the gaps that let signal thru, it's the lack of electrical continuity of the whole shield (the glue on the tape acts as an insulator).. as an example, the microwave oven also uses wavelengths of 12cm (same as 2.4 WiFi), and yet the shield on the door is a perforated see-thru metallic screen. one can never heat a glass of water by placing it outside the oven, even touching the door.. any metal works, copper foil is sometimes super expensive.. anyways, let's think things thru.. :}
using kitchen wrapping foil works fine, since there is no glue to break the electrical contact... so 'wrapping foil' and hot glue or super glue is way less expensive and works better.
another point is that one could wrap foil both on the inside and outside of a box thus creating a double shield..
for adhesive aluminum tape, one can bend the corner of the top tape strip so it touches the face of the bottom strip. also piercing the tape layers where they are stratified with something sharp creates an electrical contact in spite of the adhesive.. for copper tape, soldering is preferred.. (aluminum is very difficult to solder)
this is used to shield cavities in electrical instruments that use pickups for amplification, such as electric guitars, bases, etc.. in those applications the shield also needs to be grounded. (they also use metallic paint for this purpose).
have fun, be safe everyone
ps that box looks pretty, thanks for sharing.
If you're worried so much about the spying, and we all should be, why even have a cell phone to begin with? I'm more worried about the EMF radiation exposure (and Bluetooth is the worse than wifi) but not overly so cause fear is never a good thing.
check out SHIELD-IT FLAME RETARDANT FABRIC for RF and MICROWAVE Shielding on amazon.
I just had this great idea does brass do the same thing as copper cuz you can get a 3-inch nipple 2 caps wouldn't that make a great Fair Day it's pretty thick I don't see the Wayfarer going through there I hope you read these cuz I would love to have someone do this cuz I was thinking about running out and buying a couple of caps in the nipple if you know what nipples mean it's a small piece of brass with threads on either side it's not dirty well the brass is dirty but you know what I mean
How do I make a Faraday cage for a router to block all potential wifi signals BUT still allow the ethernet cable to leave the box!!???????
I had some success with a thick 3M anti static bag. Maybe lining it with this would improve it.
Others or cardboard in between the metal and the phone because the phone touching the metal obviously would conduct The ammo can cages for instance just need foil stuffed in the rubber gasket groove
It is nice to have a way to keep your phone of the radar but in a box like that you can't use for something like the calendar. The reason why people carry smartphones is because it has so much uses. You need to be aware of Google knowing every step you make, but to live in a time where this is possible you need to block yourself against commercials and other things they throw at you. If you do things that can't bare the light of day, buy a prepaid dumb phone or no phone at all.
The length of the sides of that box are likely resonant dipoles and the 4 sides of the box are probably a full wave...so that box itself may be acting as an antenna. At 1900 mhz , 3 inches is a dipole antenna ...and 6 inch being a full wave. Try lead sheet instead of copper
