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 items)

I never understood Tile and the rest.

The only thing I want a locator on is my phone.

You've never misplaced anything but your phone?

Does anyone remember the amazing backscatter tech by the UW kids (https://www.jeevawireless.com/)? I've been waiting on them for years now. They were supposed to be to market by now with a $0.25 chip that does 2.4GHz at 1/10,000 of the power. They have reliable functional demos doing long range transmission using 59 micro watts. They were also working on a battery free emergency cell phone.

With the new tile you put it on your keychain, and if you lose your keys the app on your phone can find them. And if you lose your phone, the keychain can find 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.
