iFixit Tears Down Apple's AirTag, Finds a Great Spot For a Keychain Hole (arstechnica.com) 76

iFixit has ripped apart Apple's recently-released AirTag, a small battery-powered tag that will allow you to track your items within Apple's "Find My" app on iOS. An anonymous reader shares an excerpt from an Ars Technica article: Like with most Apple products, it looks like some serious engineering went into the $29 tracker. The device is barely larger than the user-replaceable CR2032 battery that powers it, putting competing devices like the Tile and Samsung Galaxy SmartTags to shame with their comparative bulk. Inside, a single circuit board uses a unique donut-shaped design that crams all the components into a ring under the battery. The hole in the middle of the circuit board lets Apple pack in a surprisingly huge voice coil speaker. The speaker is just for playing ringtones so you can find your AirTagged thing when you lose it, but apparently, the ringtones will be super high quality.

The other very Apple-like quality of the AirTag is that it almost seems designed to sell accessories. The most popular use for these trackers is to help find your car keys, but out of the box, there is no way to attach a keychain to an AirTag. Instead, Apple has enabled a wide ecosystem of AirTag cases ranging from a $13 keyring holder to a $449 (yes, that's four hundred forty-nine dollars) Hermes' luggage tag. iFixit's solution to the much-demanded keyring hole is -- what else -- a power drill! The teardown experts found some suitable dead space inside the AirTag that somehow isn't blocked by either the battery, speaker, or circuit board, and after some careful drilling, iFixit's AirTag now has a keychain hole with the least possible bulk. "The AirTag survived the operation like a champ and works as if nothing happened," the site says. iFixit went on to note that the sound profile "didn't seem to change much," but the IP67 dust and water resistance rating is now greatly compromised.

      I dunno, shit happens. I have my keys/wallet box, but you know, sometimes you have your hands full with groceries or something and next thing you know you're looking and find them in the fucking freezer or on top of the toilet tank or some place weird. It really is one of those you don't need it until you do sorta things. Having said that, not gonna buy it. Another tracking device outside of my phone is just getting annoying.

          I think it has more to do with personality than age. I always keep my keys, wallet, and cell phone in the same pockets. When not in my pockets they are on my nightstand. My wife, on the other hand, never knows where her shit is at.

          You can always tell who these people are. When they walk toward their car in a parking lot, they are the ones who check multiple pockets before pulling out their car keys. I don' t think they're stupid, as the OP claims. I just think they're wired somewhat differently. They would probably call me OCD for insisting that my items have particular places. It crops up in other places, too. If I assemble something such as a piece of crappy furniture, I organize all the pieces and fasteners and then follow the directions. My wife just starts slapping things together. When things have to be disassembled to then be assembled correctly, I chastise my wife for wasting time. While she's waiting for me to organize things, my wife chastises me for wasting time. It's just a matter of priorities.

            Creatures of habit are not immune. All it takes is one subtle change outside of your control, or due to you being human and thus imperfect, and your keys are not in your pocket, or not on the nightstand, and effectively "lost" because as a creature of habit you don't actually commit to memory where something may be at any given time.

It even had rounded corners. Fast forward and Apple is stealing the same idea and doing it worse (due to lack of a keychain hole) and the fans are praising Apple.

      I have lost my keys twice, to substantial expense and great inconvenience. My solution was a watch chain. The last link on one end is threaded onto the key ring, and the other, with the lobster-claw, clips to a belt loop by the pants pocket where I normally carry my keys. The chain is long enough that I can fully operate any lock while the keys remain securely attached to me. As long as I have my pants (and I haven't been to *that* kind of party since college), I have my keys.

      I wonder how much effect these things have on your battery life. Even if you don't own one then if Bluetooth is enabled your phone is picking up the transmissions and having to do a bit of processing to decide that they are of no interest to it.

      If you do have one of these tags then the app will be using location services every time a tag is seen (regardless of if it is yours - the community feature tracks other people's tags too), and then consuming a bit of data to report it all back.

Putting a ringtone on an iPhone can be an exercise in frustration if you don't already have it on another iDevice or if you're not buying it from their walled garden.

        Apple users have had the ability to track every iDevice they own, anywhere in the world, since basically forever.

        AirTags integrate into this technology, and simply expands it to allow you to tracks basically any object you own, as long as you can fix an AirTag to it.

You already can't put on one your phone (so that you can find your phone with your phone), now you can't put it on your remote control or keys either, and that covers the three most commonly lost items. (and before you ask, your glasses are on the top of your head where you pushed them up to look cool)

      The keychain hole is actually a $13 or more accessory. Seriously.

      So IMHO, the antenna is not the problem. And if it was, they could have put a tiny hole like sometimes do with USB sticks and old cell phones, too small for a key ring but perfect for string, like for attaching lanyards.

      I think the reasons are: it looks better without a hole (according to Apple), it is not always needed (ex: baggage tags), and selling high margin accessories makes good money.

  • Was it too hard to super-glue a little ring or tag or whatever to it so it could be put on a key ring?

    Or was it too hard to use a tiny bit of extra plastic to, I dunno, make a little tab with a hole in it so it could be put on a key ring?

    It seems like a retarded design not to include a hole but what do I know, I use an Android phone that lets me load music easily or change the ringtone whenever I want without jumping through hoops or finding a PC to load iTunes on.
