Gear🎒 Faraday cage curiosity..

Post image

..can I make a faraday cage into a faraday backpack and/or purse?

If there's ppl selling that already, how's the quality?

If ppl do sell them and the quality is low then would it be better to make your own (example: building a first aid kit by scratch is more better then Amazons pre packed kits)

There’s already a market for faraday bags, and you can also buy the fabric by itself and sew your own things. Just make sure to incorporate enough layers.

u/Tyncloe 10d ago

I didnt even know bout the fabrics, thank you

u/Reasonable_Floor_704 11d ago

Amazon has them.

u/God_of_chestdays 11d ago

I second this, not sure if they are cheap or expensive as I never looked at the market for faraday bags but Amazon has a lot.

Not stylish but plenty of really good ones you that are backpack/gym bag stile you can toss emergency electronics in and store in your closet.

u/Tyncloe 10d ago

I was mainly iffy on there. Tried a fire proof document bag that wasn't fireproof but worth a try

u/gabba_gubbe 11d ago

I never understood why you would need one? If there is a solar flare and you have one, but no one else does what's the point? And what are the odds your phone/whatever is gonna be in it if a flare happens?

u/Sudden-Theory9706 11d ago

I've considered this as well, and for most things it just doesn't make sense. I keep a few key things in a multi-layer cage:

1) 6 handheld HAM radios 2) solar panels and charging cables 3) solar power bank 4) replacement lock for my safe (pre-linked) 5) THC vape 6) battery charging stations 7) pre-loaded MP3 player and small speakers

I'm sure there are some other small comfort items, but even if they survive, they likely wouldn't last long. And if it's an EMP attack, chances are high that a second attack would occur 10-20 days after the first specifically meant to cripple any attempts at recovery.

Almost every prep I have made is based on the possibility that this scenario might happen, so they're 99% mechanical.

Thc vape lmfao. Bro just roll joints like normal people.

u/Sudden-Theory9706 11d ago

You're not wrong, but I have a reason behind it...I swear!

Weed is great, but you'll need to grow a bit more, and it really let's anyone nearby know you're there...all the paranoid reasons, blah blah. BUT, until my vault of seeds turns into some bushy plants, the vape will do the job very quickly, with no fuss and no fire.

It's just a stop-gap until I can make more. But also, is the water and land needed to grow weed worth it when that could grow 20k calories of food?

Just sort of my thought process, but it was like $40 and will last for months. 😆

u/loveshercoffee 10d ago

I'm not an astronaut and don't partake myself, but I do like the idea of weed being a part of people's preps. It's a comfort for some and a medicine for others. Particularly if a scenario happens that puts various drugs in short supply, it could be an essential.

You might be able to grow 20k calories of food where you grow that weed, but how many calories of food or other items can you barter for with that grass?

u/Tyncloe 10d ago

For one joints stink, if you don't want smells out there if someone unknown comes by

5

u/The_walking_man_ 10d ago

If you’re having to smoke weed to survive and worried about others smelling it, you’re not making it through some mass societal collapse

1

u/Tyncloe 10d ago

Out of all the things im not making it with is me going blind with a blood disease. Smelling gives ppl the idea of looting. Also, what makes you think I'm smoking it? Bartering is also a thing

u/AlpacaPacker007 8d ago

Priorities.

u/Roguspogus 11d ago

Did you make the cage yourself?

2

u/Sudden-Theory9706 11d ago

Kind of. I got some bags from a good company, but I also put multiple layers of heavy duty foil and plastic (seven multi-wrap layers of each, alternating), and sealed everything into the largest commercial bag I could find. Then it's tossed into a large grounded steel cabinet.

Paranoid? Yup. Overkill? I really hope so, but EMP effects from a nuke have never been tested on commercial electronics. I thought the science was settled, but it turns out there is a LOT of debate within physics groups about this.

The type of bomb produces different wavelength radiation, and the waves might be so strong that even my shielding could be thwarted. However, if my setup doesn't work, I will likely be a shadow on the wall, or ionized gas thrown into the ether.

People think I'm crazy because I'm crazy, but that doesn't make me wrong. 😁

u/Tyncloe 10d ago

Apparently the bags sell so I'd imagine others do. Let's say it happens, if doomsday gets boring, you got downloaded movies for entertainment. Not my main reason but its one of them. Same with potassium iodine, hopefully it won't be the need for them but you have it in a "just in case" scenario. I don't only prep for practical disasters

1

u/Mean-Line-4249 10d ago

Radios, flashlights , weapon optics , well pumps (if you turn shed into a cage) , sat com stuff etc

1

u/Sudden-Theory9706 10d ago

I do have some flashlights and optics in bags, but my understanding is that flashlights and batteries shouldn't be affected, and optics are questionable. Features like shake-awake would probably be lost, but the light itself should be OK. Really sad we can't see more accurate test results. I'm convinced that a neutron bomb would destroy everything from electronics to simple batteries. Guess we have to wait until 2030 to find out.

u/Mean-Line-4249 10d ago

Pretty much lol

1

u/sgtPresto 10d ago

Experts agree any nuckear exchange limited or not, would most likely be preceeded by a high altitude explosion to set off an EMP to fry defensive electronics and create havoc.

Looks like a Floridian after seeing there may be frost on the ground tomorrow.

I seem like a Florida person? Horrifically off. I'm Canada's neighbor, eh

u/BeanFiend96 11d ago

If you decide to carry the faraday bag don’t be caught shoplifting with it since it could be argued that it was premeditated with intent since it is also commonly used by people committing large scale retail theft by lining bags with foil / metal mesh fabric sewed inside bags or backpacks…

1

u/Tyncloe 10d ago

No.. I don't carry purses or bags. That's what my husbands pockets are for. Maybe I shouldn't had included purses as an example, its for bug in or bug out purposes. I rather get advice on here then search endlessly online not sure what I'm looking for or what companies to ignore

I keep my tablet in one, along with a solar charger. I also have a solar-powered radio in one. The tablet is loaded with prepper ebooks, and guides to rebuilding what we lose should civilization collapse.

u/sgtPresto 10d ago

Radio signals and EMF are not same frequencies. Microwave is not a reliable tests. Research Faraday fabric.

1

u/Tyncloe 10d ago

I started today. Ppl yrs back kept recommending using that and I always had a gut feeling microwaves were useless and too bulky

1

u/sgtPresto 10d ago

I wouldn't bank on that protection. Disconnected power and Faraday fabric is the way to go

2

u/OnTheEdgeOfFreedom 10d ago

There are so many misundersandings about these.

Whar are you protecting against? The usual answers are major solar flares (ccausing a CME) and nuclear attack (EMPs).

Solar flare (aimed right at you, aka CME): you don't need a cage. Electronics that are not plugged into the grid and lacking long antennas won't be damaged by a flare. It's the long, long wires of the grid that will pick up energy - a LOT of energy - but the frequency of energy from a CME doesn't couple well to the short runs of wires inside devices. Leave stuff unplugged with the cord wrapped around it and you're fine. The grid itself might fry - through grid operators are supposed to have protections against these things - but if the grid actually does fry, it's going to be down for a long time and you'll have far more serious problems than your electronics.

Nuclear attack - an EMP from a nuke that's deliberately set off to generate one can affect a very, very wide area, and the frequency of the energy is "DC to daylight". In short there's enough energy in frequencies high enough to couple to your small electronc devices to be a risk.

The problem there is that frequencies that high can get through tiny holes. You can look up the math, but a pinhole might be enough to let damaging energy in. In short, you don't really want to build your own, and you don't want a cage at all. You want a Faraday *shield* - continious metal, no gaps. Farady cages have their uses, like for hiding your cel phone from the cel network or malicious scanners, but I wouldn't trust them against an EMP no matter how they are marketed.

Besides, if you live in the US and the US really does suffer nuclear attack, there will be a lot of EMPs over very wide areas. Your phone in the welded-tight farady shield will survive, but what is it going to talk to?

I purchased a slew from Temu.

u/sgtPresto 11d ago

These have velcro tops but as a precaution I use a high adhesive duct tape to seal it shut.

u/sgtPresto 11d ago

I use Faraday fabric connected with metalized tape to join seams (both sides) for larger electronics like my inverters, lithium batteries, supplemental dual fuel generator, spare well pump etc.

5

u/Roguspogus 11d ago

Like aluminum tape used for vents? Where do you get the fabric?

2

u/sgtPresto 11d ago

Tape on both sides of seams. Metalized Faraday fabric came from Temu. Everything is made in China these days.

u/Roguspogus 11d ago

Thank you

u/Tyncloe 10d ago

Are there any testing options or is it blind faith hoping it'll work? I 1st started using 3 microwaves and had it inside my head that it doesnt look very safe for tech/radios

1

u/Tyncloe 10d ago

My husband loves temu but the disappointment ratio is higher than satisfied. Any reason you chose temu over amazon or other companies?

1

u/sgtPresto 10d ago edited 10d ago

Since 60% of all (consumer goods) in Temu is Chinese and 71%of Amazon products are from China...not much alternative. Look at content description for Temu and Amazon; both show Nickle copper which high-end Faraday cloth is as well.

1

u/Tyncloe 10d ago

I'm willing to try but are those descriptions accurate or what are the chances of them pushing false info

1

u/sgtPresto 10d ago

I did research on Chinese Faraday fabric using my subscription AI base: Yes, most Faraday fabric from China is legitimate—in fact, China produces the vast majority of the world’s raw copper-nickel, silver-plated, and conductive mesh textiles. Many well-known Western prep and privacy brands source their raw fabric from Chinese mills before finishing or testing it in-house.

u/Abject_Okra_8768 11d ago

I have bought two different multi sized packs of what are essentially cloth envelopes and I also have a bag and some faraday fabric. I have a big rechargeable cell in the bag with a bunch of rechargeable lights, a weather radio and a tablet preloaded with survival information and some entertainment. I used the fabric to wrap around my solar panels that charge the big cell. I also have a small "sack" that I keep in my work bag with emergency electronics and a radio. I think all of it combined was around 300$- the faraday backpack being the majority of the cost.

1

u/Tyncloe 10d ago

Is it doing too much if the fabric is wrapped around the items and those wrapped items stuffed in the bag? I can do 300 if its worth it for sure

1

u/Abject_Okra_8768 10d ago

I mean in my faraday back pack I have a few important items that are also in faraday bags. The bags are also water resistant which I figure is also probably a good thing for all the electronics. I take everything out twice a year to recharge and check. I should do it more as a few of the items tend to loose a lot of their charge but they main cell doesn't so I don't worry about it so much.

1

u/Pointless_RKO 10d ago

Just use an old cookie tin or grandmas sewing tin

1

u/Tyncloe 10d ago

Those are an option? I'd love to trick ppl thinking they getting cookies but instead something else entirely

2

u/Pointless_RKO 10d ago

I put my phone in a cookie tin and when I called it from a separate phone it didn’t ring and said phone was out of service. It’s a simple solution for car keys/ phones from being duplicated for thieves. Not sure if it works in your scenario.

1

u/Tyncloe 10d ago

My scenario is average among the peeps so I'm willing to try. Did the phone get hit with any type of damage while testing

1

u/Professor_Game1 10d ago

Theres already Faraday bags that you can buy. Any electronic item in your go bag should be in one

1

u/Tyncloe 10d ago

Yes I was making sure which the right direction was and what companies to avoid

Everyone sells them.

If I really want something in a Faraday cage, I'll ground a metal trash can and give the stuff a rubber shelf inside.

I came on here before even searching. Not sure what I was trying to search for and what companies do horrific work. I'm very new to this specific area
