You’d need a laser powerful enough and those are hard to get. Those are super dangerous I’d recommend people stay away from them if they don’t know about how they work.

Absolutely. 500mW+ lasers can injure human eyes in a fraction of a second, even from a reflection, similar to how they can destroy a camera sensor.

They’re not particularly hard to get online in the USA though.

Spray paint poles are cheaper and safer. Tungsten carbide sawzall blades aren’t that expensive either

just use a circular saw with a medium tooth count blade designed for metal.

a six inch circular blade can cut up to 300 times more than a reciprocal saw blade when you compare tooth to tooth.

They also cut faster, though are loud as hell.

That’s a bad idea. You don’t want to get a stranger, or yourself in the eye.

Anything that would do meaningful damage to a camera sensor will easily do that to human eyeballs if it refracts or gets reflected.

Especially for cheaper high-power lasers, which may not properly filter out invisible wavelengths like IR.

I don’t think that’s true? The lidars on Waymo have been known to damage camera sensors but are safe to the eyes. By damage, like a pixel or two go out, but that’s from a random hit. If you did it right you could do more damage.

Interesting. I would have expected cameras to be more resilient between both their internal filters and the sensor material being tougher than human eyeballs, so anything that could overwhelm that and burn out a camera sensor would be able to ruin someone’s vision almost instantly.

This says its about the specific wave lengths and our eyes are okay with the ones bad for cameras

If I hadn’t heard of this happening before though I wouldn’t have guessed this to be the case.

Thanks to signal trace, they don’t need functioning cameras so…good news everyone!
