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.

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

It's not nearly sturdy, weatherproof, slim, or loud enough to work there.

The 30 foot range and assumption that it is still in the location where your phone last connected to it are further limitations...

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.

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?

Different people are different.

I now keep my personal things in the same place at home >99% of the time, but it's taken me decades of training to get to this point.

For example, I used to walk in with my keys, and would be ready to put them into their home. But there could be an interruption between the time I used the keys to open the front door and when I put them in their home. For me, that situation would often cause me to put my keys in an inappropriate place, which often caused them to get 'lost' later on.

The behaviour modification, for me, was causing me to resist any reaction to any interruption until the necessary things landed where they belonged.

Different people are different.

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.)

> I felt the same way until my wife lost her car key and the dealer wanted $1,200 to replace it. !! More info, please. (:

Modern cars are so up their own arse in those kind of things that everything costs an arm and a leg to service or replace. I'm probably sticking to 90s/earlier cars as long as I can.

They've regressed in so many ways - touch screen radios are an abomination, exorbitant key replacements/servicing in general, annoying gas flaps you can only open from inside the car, digital pedals that are usually way over-responsive.

Too many over-engineered points of possible failure - when my mother got her 2008 Nissan a while ago we couldn't figure out how to open the gas flap, turned out a handle had fallen off of a lever hidden somewhere on the floor to the side of the seat. As if gas siphoners don't probably just carry around something to pry the flaps open. And more seriously, wasn't someone recently unable to get out of a burning Tesla because the digital door handle didn't engage? Not to mention remote exploits have been found that theoretically let hackers take control of a car remotely while it's being driven and control the steering/brakes/acceleration/etc. I'll pass on the incrementally better mpg/safety.

An electric conversion of a 1940s led sled is my dream car.

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 like the idea behind Tile, but there've been so many times where the tile I had was sitting within 3 ft of me but my phone couldn't locate or ping it.

At this point, I'd just settle with set top boxes (is that what they're called still? The DirecTV, Dish, etc. digital ones) that had a button to locate the remote.

And thus begins a Cambrian explosion of new spy devices that run (practically) forever off a button cell. The bleed/drain rate of many batteries is far more than 1mw.

FYI this is not terribly new – BLE was already extremely power efficient and could easily run for > 1 year on a watch battery

you're not going to be able to stream audio or video from a device like this, but BLE was not designed for that anyway.

That sounds more like you just need to have the place that you put your keys immediately by the door.
