It only complains once that the battery is low and never again, I've run into a dead battery when searching for an AirTag multiple times.

This has not been my experience. I’ve had multiple AirTags notify me multiple times over a period of months that I needed to change the batteries.

Earlier quoted context omitted.

Here [0] is the datasheet for the batteries used. 25 year shelf life is spec'd. I have personally run these cells buried underground, and gotten 4.5 years out of 4 of them, though my application is just for fun and likely not as power conservative as an AirTag. [0] https://data.energizer.com/pdfs/l91.pdf

Ooh what's the application underground?

So I attend this local annual event that has a time capsule. Each year, we bury one and dig up the one from 5 years ago. This has gone on for several decades, and people are always thinking of interesting things to put in there.

I made a little electronics project that is somewhere between "what happens inside a time capsule while it's buried?" and "what if you could wind a watch once and have it still be ticking in 5 years?"

I nearly forgot that I made a project page for it: https://hackaday.io/project/160740-low-power-environment-mon...

I dug up the first one last year and it had made it to 4.5 years, and I'm actually due to dig up the second one next week.

order results from consequences. it's ok if you want to be timid, but don't shame others for helping restore order.

Is fear of punishment the main reason you aren't out there stealing the things you want and killing those who get in your way?

For many people, especially from some terrible cultures I've personally met, the odds of being punished are really the only deterrent.

i wish police do honey trap more often like put expensive equipment. That will definitely reduce lot of crimes.

Didn't that work well with car theft? I believe reading something like that

I've retrieved stolen bikes, one because of an airtag. Showed up with a couple friends standing by but not trying to be intimidating. It's mostly about staying calm and telling the person this is mine, I'm taking it. They always say "no it's my friend's, you're gonna piss him off" or "I just bought this" or something. Maybe you offer some fraction of a "reward" to smooth it along and cut your losses. Don't try to start a fight and it generally goes OK. Also, try not to accuse them of stealing, they'll just get defensive. "It's someone else who is screwing us both, but this is mine sorry."

What is the point of CNC machined screws? I have only seen that type of thing on specialized military applications and the like. I'm sure standard rolled screws would be just fine...

I had the exact same thought. The screws are recessed, so knurling is unimportant. I love the idea and will buy some for the cars but give me a stainless m5, hex cap head screw, I don’t care about the process.
