I've written a bunch more on the link (+photos are there), but essentially this uses 2 fingerprinting approaches: - retro-reflectivity of the camera sensor by looking at IR reflections. mixed results here. - wireless traffic (primarily BLE, also looking into BTC and wifi)
For the latter, I'm currently just using an ESP32, and I can consistently detect when the Meta Raybans are 1) pairing, 2) first powered on, 3) (less consistently) when they're taken out of the charging case. When they do detect something, it plays a little jingle next to your ear.
Ideally I want to be able to detect them when they're in use, and not just at boot. I've come across the nRF52840, which seems like it can follow directed BLE traffic beyond the initial broadcast, but from my understanding it would still need to catch the first CONNECT_REQ event regardless. On the bluetooth classic side of things, all the hardware looks really expensive! Any ideas are appreciated. Thanks!
I would like to draw attention to this gem of wit, easily the best I've seen in a long time:

So all the people blathering about camera in public have a moot point. All the whining does is prevent the fairly obvious camera being put into devices.
But if someone wants to record you in public otherwise, they will and there's nothing you or any of us can do about it.
I think the same answers apply here: because making it harder to be casually recorded sends a clear signal that you don't want it, and now the act of recording goes from being an oversight to a deliberate, sometimes punishable act.
It's like people listening to music without any headphones on the train — technically has been possible for ages but previously would've gotten you told to turn it off. Now it barely gets a raised eyebrow.
Can you prevent people secretly filming you? No, but most people still don't want it be become accepted behaviour, even if to you that's all just "whining and blathering".
No they don't. I'm a beginner lockpicker and so far I've only been able pick a 2 pin lock once. Have not been able to repeat it. Have not been able to rake any lock open. Lockpicking is much more of a skill than people online give credit. People on the Internet always acting like lockpicking is just as easy as using the key for any old novice.
But I don't get sucker punched very often, so it seems like there probably are things that can be done about. Norms, consequences, etc etc. "We live in a society".
My then-12 or 13 year old picked the lock that came with her beginners lock picking kit within just a few minutes. She picked most of the small locks that I could find - I think an Abus finally defided her. And she has had no interest in the hobby since.
