Pretty sure those devices that block cellphone and radio signals are illegal in public and people have gotten in legal trouble for that

The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rules (interactive)
Rule 1- All posts must be legitimate questions. All post titles must include a question.
All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.
Rule 2- Your question subject cannot be illegal or NSFW material.
Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.
Rule 3- Do not seek mental, medical and professional help here.
Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.
Rule 4- No self promotion or upvote-farming of any kind.
That's it.
Rule 5- No baiting or sealioning or promoting an agenda.

Rule 6- Regarding META posts and joke questions.
Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.
On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.
If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.
Rule 7- You can't intentionally annoy, mock, or harass other members.
If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.
Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.

Yes you cannot start jamming common used frequencies, or any frequencies really
Creating something that damages nearby electronics? Yeah, that's probably not going to fly. It really doesn't matter if it only damages things that actively film/photograph you. Like, it'd be illegal if I walked up and hammered every camera that photographed me too.
It'd also be illegal to point a laser light into a camera to damage the sensor
ITT: People debating whether such a shirt is possible and not answering the actual question.
Im all for this. Im all for all the side discussions that emerge from a post like this
A similar thing that might be possible is to create a shirt that shows something that exploits a vulnerability in software. Some hardware can be bricked by software (this used to be the case for MacBook batteries).
Might not cause damage but there is the Camera Shy Hoodie: https://www.macpierce.com/the-camera-shy-hoodie
Instructions for how to DIY provided, so it doesn't have to be a hoodie.
happy cake day
there was an x-file episode, where the guy emits radiation, which pratically jams cameras, which also gives him xray vision. and also posess the ability regenerate a whole body.
Although that really only works as long as the camera doesn't have an IR filter in place.
If the camera has an IR filter, how would IR be able to make night viewing possible?
It wouldn't, and I think the other responder, while saying a true fact, may have misunderstood this question's purpose.
The hoodie will only work with cameras that support IR night vision (most security cameras, no IR filter), but won't work for most others (phones, dash cams, SLRs (filtered)).
And the dork in me must say, Raspberry Pi offers their Camera Modules in both formats, because noyce.
It works in the opposite. With the IR filter you get a nice colorful image in daytime, but not the IR lights at night
maybe if its wearing a shirt with radioactive elements, usually its lethal amounts.
if you invent some passive way to damage tech by just being in its vicinity. not only would it be illegal. it would be a super weapon.
bro's got the level 9 EMP aura
What you describe is simply not possible with a passive material. Funnily your example of something shooting lasers is probably the only thing that could come close to actual damage
The most you can do is one of those adversarial patterns that just confuses the white balance and autofocus. There is nothing you can do to affect someone shooting in manual mode
If you could damage a camera by pointing it at something, the manufacturer would fix the issue before selling it, because no one is buying a camera that does.
Rick and Morty did this once, Rick simply put on a hat with a QR code that made a robot army recognize him as a high level commander.
A few days ago I read a short story, comp.basilisk.faq by David Langford, which sketched a world in which specific images could irreversibly crash the brain, leading to a full scale worldwide ban on images on the internet and many other places as well. The story postulated hundreds of potential info-hazards with many of them simple enough to be applied via stencil and spray paint. Two of them are branch families of the Mandelbrot set 'and no we won't tell you where, do not look'
Other examples;
- Snow Crash — Neal Stephenson
- Blit — David Langford
- The Atrocity Archives — Charles Stross
- Doctor Who — “Blink” / “The Time of the Doctor”
- SCP Foundation — SCP-096
- SCP-7387 (“The Mathematician’s Grin”)

Recently, there were news about the LIDAR of Volvo cars destroying camera sensors when they were aimed into the direction of the IR laser beam. Yet, this is not a passive item.
Even that was debated. No one proved it continued when you took another video, just that it broke the video of the lidar itself.

You could maybe defeat LIDAR with retro reflectors or something. Probably not, but that's the only case it'd be possible realistically, since it's actively shooting lasers out that you could reflect back, without actually locating the camera. Anything else, yeah it'd require actively finding the camera and attacking it, since it is only receiving light. I guess if you wore something bright enough to damage any camera looking in your direction that would also work, but I don't think it'd be considered passive, and you'd also blind everyone else who can see you, probably permanently, and it'd require huge amounts of energy.

OK you're going to need CO2 gas, 2 mirrors, a glass. Container and a high voltage capacitor.
...
Step 3454674) charge the capacitor to 60078V.
Step 5746678) now run!
Strap a lidar emitter to yourself. Those car sensors have been shown to damage cameras.
If you want privacy from cameras, there are those hats with strong ir leds. Not sure how well they work.
The FCC has (had? Do they still exist?) rules about this, very straightforward.
My dude is trying to create a shirt that just continuously recharges and fires EMPs lol
- Create sentient AI
- Let AI take control of the internet upon receiving the QR code
- Wear your t-shirt containing the QR code, show it to a camera connected to the internet
- Now AI takes over the world
Black Mirror S7E4 - Plaything
That was an episode that ended right where it started getting good. Not that the episode was bad before that, but it left me wanting more of that, not a jump to a new premise in the next episode.
The story of this episofe had enough potential for a 6 episode spinoff series. Or maybe 4. Anyway 1 was way too soon.

It's not possible to damage cameras passively, so there isn't an answer. But if it was possible it probably would be made illegal to wear those around cameras.
maybe if its emitting lots radiation
More like illegal to wear anywhere in the USA considering that we're quickly becoming a surveillance state.

I think it depends on whether it’s active or passive. Active - e.g. a laser that damages a camera sensor, then yes, your device is actively damaging someone else’s camera - deliberate property damage. Passive - e.g. reflective strips so the exposure is bad, a pattern that is hard to focus on or similar- that’s fine - camera owner is making a decision to expose their gear to the environment. Even if, say, it’s a changing pattern that deceives the autofocus into working constantly (no, I don’t know exactly how that would work, but it’s the best I can think of at short notice) so it wears out faster.
It depends a lot where your story happens. Laws are quite different.
In my country, this little detail would save you ....
it's not like my shirt is emitting damaging laser beams or anything, it's entirely passive.
... unless you were deliberately wearing this for the purpose of doing such damage, and somebody could prove that.
