Hah! My USB sticks prevent nuclear war using nothing but the good feelings I pump into them.
If you happen to have a nuclear war, it just needs to be recharged. Send it back with a self-addressed, postpaid mailer to send it back in, and I’ll do so for a nominal fee - if I have any good feelings left to supply. That fee and the currency it is determined in will be decided on depending on what you have left that I consider valuable after a nuclear war. If you have fine marijuana and cheap breakfast cereal, you’re probably set. I’ll probably have all kinds of good feelings for you if you can pay in those.
Seriously to the OP: if it’s not a Faraday cage, it probably wouldn’t be doing much to protect you from electromagnetic waves, 5G or otherwise. Faraday cages aren’t that hard to build, you could probably build one after reading up and making a trip to the hardware store tomorrow. But putting one in a USB stick would be incredibly hard. Making one that’s nothing more than a cheapo 128M storage device is pretty much impossible. The other claims about USB sticks in this thread are just as believable as one that protects you from 5G.
Actually, functioning Faraday cages are very hard to build. As soon as you put a door in one, it’s like putting a screen door on a submarine. Shielding a room is a multi-thousand dollar project.
I had a device FCC tested and I went into their screen room with my cell phone, closed the door and… I still had reception (not very good, but it was there).
Well, ok, the practice is hard. Still more effective than anything a USB stick is likely to provide, no?
ETA, totally off topic, but wouldn’t it make more sense to build in something like a light trap in a darkroom (basically several parallel hallways connected at one end) than putting a door on the thing?
Radio waves reflect - so, you really need the surface to be completely sealed. The doors have conductive gaskets and are sealed with a latching mechanism that tightens the door down to the frame. Also, the copper mesh is expensive, so you want to use as little of it as possible.
Well, that’s from Cloudflare, who provide security services for websites among other things.
One of the things it loads is a javascript, which acts as a challenge to the browser, testing for features that many automated tools (used for scripting DoS attacks) do not support. This javascript may also fingerprint the browser, providing nearly unique identification even when multiple browsers share the same address (via a proxy or similar). Once this process is complete, the validated request is then sent to the website.
If the browser does not validate via the javascript challenge, the request may get further validation via a CAPTCHA or some other mechanism, or it may just just be dropped.
I was gonna say. It practically reads like a parody.
“wearable holographic nano-layer catalyser”
“quantum oscillation”
“coherence of atoms”
“cardiac coherence via plasmic support and interactivity”
“life force frequencies”
“quantum biological shielding technology”
I’ve recently developed enantomeric technology that prevents chelation with isotopic species, ensuring that biodistribution of pharmacology will not allow reuptake of neurotransmitters.
FYI to all: I also get a second window asking me to click on a "t"captcha box to show “I’m human”.
I’ve only ever that that once before when I first entered a website. I stupidly clicked and had viral adware downloaded in the background.
If you did get that 2nd message and clicked on it, I’d recommend you immediately scan your hard drive. This entire thing is definitely a scam, but it may just be one to place adware etc on computers.
Hehehe, after reading your answer, I thought “Yeah, but light reflects, too!” But then I thought about it harder, and realized that visible light is a much narrower range than the radio spectrum. We’ve got a lot of cheap materials that absorb them well, we call them “black”. Things that absorb the radio spectrum? All of it? Pretty rare.
So, having an open structure like a light maze would indeed be difficult. Even if you set it up to absorb and/or reflect back large parts of the radio spectrum, it’d likely just be a wave guide for a large enough subset that you’d wish you’d just put a door on it.
Plus, even in a darkroom, it’s there to keep absent minded folks from ruining your paper by opening the door.
Necklaces and accessories claiming to “protect” people from 5G mobile networks have been found to be radioactive.
The Dutch authority for nuclear safety and radiation protection (ANVS) issued a warning about ten products it found gave off harmful ionising radiation.
It urged people not to use the products, which could cause harm with long-term wear.
The link is in Dutch but Google Translate does a pretty good job
We have a couple walk-in, RF anechoic chambers at my workplace. And you’re correct… they’re elaborate and expensive. The doors contain very special RF gaskets. And the rooms needs to be certified every year.
If you have a cellphone on you, the battery will quickly discharge when you’re in the room.
I don’t know what any of this stuff mewns but Im sold, um, prices are listed in currencies I don’t have, uh, cowrie shells anyone?
@Crafter_Man, why would your phone quickly discharge? Or do you mean faster than normal as it boosts its signal to max trying to find a tower it’s not gonna find?
Sorry, that one threw me for some reason
ETA wait, are you guys telling me my chainlink fence faraday cage … ISN’T effective against the cia/nsa/fbi satellite?
One of my favourite YouTubers, DiodeGoneWild, has a few Geiger counters amongst his collection of electronic bric-a-brac.
He ordered a few “negative ion“ radioactive wands and pendants with alleged health benefits and so on off eBay just to check them out. What amazed me was that they were all actually radioactive.
Given that they are a complete scam, it surprised me that the scammers used radioactive material. I would have assumed they wouldn’t bother given that their customers are totally clueless anyway.
I’ve worked in several Faraday cages, tuning radios.
I worked for a place that made computer terminals with radio data links; this was long enough ago that the links were 1200-baud and 2400-baud frequency-shift keying. The radios were configured with crystals to tune to specific frequencies. (A big part of one person’s job was to order and keep track of the crystals…) Each installation required an actual radio license from the CRTC, FCC, or an equivalent agency. The radios were mostly FM in the ISM band around 150 MHz.
The cage was required to give us a place to tune radios for other countries, which transmitted on frequencies that were not permitted at home.
The first cage was a frame of lumber, maybe three metres tall and two metres square, enough to hold a work table and a chair. Both the inside and the outside surfaces of the frame were covered in copper screening, soldered and riveted. Power was passed into the cage through a shielded box. I presume there were filters inside.
The door of the cage was an equally thick frame also with copper screening on both sides. There were fringes of copper tabs or prongs on the inner and outer edges of the door that brushed hard to contact the inner and outer edges of the doorframe. To close the door, you had to pull hard and make sure it was fully seated.
The cage looked crude as hell, but it worked. I would go in and close the door and my FM radio would receive nothing. It was strange because there I was in the middle of the production floor, quite visible, and able to talk to anyone outside. There was a fan blowing air through the screening. But in radio terms, I and my test equipment might as well have been on another planet.
When I think about the amount of detail that would have gone into building even the crude cage, it would easily cost a few thousand dollars even then.
Later, the company got an actual room as a Faraday cage, with opaque walls and a shielded ventilation system. It seated two or three techs and my co-worker and I would retreat inside with a tape player and plenty of dance music…
Yea, you and @gnoitall are correct… I should have said “faster than usual.” When your cellphone can’t find a tower, it has an anxiety attack and starts to transmit more frequently, and at higher power. Even when you’re not using it.
