You've never misplaced anything but your phone?

Creating more electronic waste for that once in a year time you need to locate your keys VS spending 15 min to find them. It's nice in theory but it doesn't really solve anything, a bit like Juicero, nike self lacing shoes, &c. If you start putting bluetooth tags on everything you could potentially forget somewhere you're in for a wild ride.

I use tile to find keys at least once a week.

Im envious of your ability to keep track of your things. I end up needing to use the one of my tiles to find either my keys, phone, wallet or work badge almost every other day.

When the batteries in them go dead its easy enough to to swap them out myself for new ones.

Also great for parents with children of any size, just place it under the insole of their shoe.

Yeah, I was confused about that as well. What are they talking about?

I'm not an expert, but I presume "magnetic monopole antenna" refers to a monopole antenna[1] with some affiliation with magnetics. I presume the word "magentic" came from this description in the article: The key part of an oscillator is the resonant tank circuit: an inductor and a capacitor. Energy sloshes back and forth between the inductor’s magnetic field and the capacitor’s electric field at a resonant frequency…

Ah, that could be where the confusion came from.

> I presume the word "magentic" came from this description in the article

A poor choice, then, since magnetic monopoles famously don't exist (or aren't known to exist). But, mistakes happen.

Wow! Forgive me, but why can’t you just keep them in the same place? My wallet and keys are 100% of the time in the same place when I’m at home, and my phone is either in my pocket, my hand, charging in a specific spot, or on a random surface in the house. That last one is rare, but happens. It takes roughly 30 seconds to walk through the house and find it. What am I missing?

I'd love to see what kind of range we can expect from that haha. Still a great achievement for BLE! I have an iPhone and often find it via saying "Hey Siri", and have sorely wished for a way to locate more "mundane" objects, and if this were to ever cost around the price of an ESP8266 it'd make that possible. (Yes there is tile and similar tags, but those are expensive, and I mean to have a tracker on a bunch of item…

I never understood Tile and the rest. The only thing I want a locator on is my phone.

People lose things.

What would be the distance range of such tiny transmitter?

like any transmitter, this depends on the gain of your receiver :)

And the stuff you have to penetrate. I turn the power down to -40dbm on one of our products during "Just works" BLE bonding to help minimize the surface area but I have the luxury of thin plastic enclosures, decent trace antennas, and the ability to force the user to place the devices right next to each other.

I would LOVE to have something on my glasses! Even just something to tell me I'm in the same room. My prescription is powerful enough that I need them, generally, but weak enough that I take them off often at home. This also means I lose them a lot and I can never quite seem to remember which room I was in when I removed them. :)

people are willing to sacrifice privacy for convenience or they are ignorant of the sacrifice itself.

I never understood Tile and the rest. The only thing I want a locator on is my phone. I felt the same way until my wife lost her car key and the dealer wanted $1,200 to replace it. (It turns out it's not the electronics that are expensive, it's the crazy engraving they use these days.)

More info, please. (:
