What would be neat is an extended life battery case...holds a larger coin cell or cylinder shaped 3V cell for 7-10 year life as an asset tracker. The airtag electronic half inserts on the end of the now larger plastic battery housing half.
Andrew, love the video could you please make one and i will pay to purchase an airtag plus shipping and pay you 100 bucks for you to make an airtag card and send to me?? Thank you!
Would a piezo speaker work here? Very low profile, very loud and you could add more if needed. Thinking something like this at digikey etc FT-23G-3.5A1W035 SS316
Would it be possible to have someone in China manufacture a PCB with the outside design of whatever I want the card to have on the outside, and with a simple (custom) board that can be picked up on by iPhones (that would send the location to Find My servers) but without NFC/Bluetooth/speakers? In other words, would it be possible to, in the same way that a Hackintosh is a non-Apple PC running Mac OS, have a non-Apple manufactured board connect to the Find My servers?
SUPERB! I can't believe this video popped up for me one year late! I haven't looked before commenting here but I hope to see this as a Matter-compatible device!
Just stumbled upon this. Why wouldn't you print a cover instead? you can even groove the cover to accommodate the wires. Add channels to the base and rails on the cover, you can slide them over and somewhat secure it.
ridiculous. these millenials. SHM. they already have a wallet card made by chipolo. don't need no heat gun or any of this crap. with a 2 year battery and its thinner than what you just made.
I would assume the construction of the AirTag is what made it work so well as a speaker. The plastic is probably similar to ABS if not ABS. The way that all the parts are secured essentially turns the entire white plastic surface of the tag into a speaker cone. I’m sure you’ve realized this, but I saw you were just adding a piece of plastic on top and expecting it to be as loud. The reason the AirTag worked better is probably because all the edges of the “speaker cone” were secured in a rigid manner on the original construction which doesn’t waste as much energy as your version and makes it louder just like a real speaker. The magnet is also secured rigidly at the back of the voice coil to make the movement much more predictable and stable thus increasing movement accuracy and in turn sound quality and volume levels
@andrewngai - i would still like to see a card made with 4 CR2012 batteries in parallel so we can have a card that is thinner at the edges, it might also be possible to shave down the board by removing some of the edge plastics, then sandwich the whole thing in .1mm protective plastic, or even make it waterproof again. I'm guessing with the board in the middle and the 4 coins at each corner, it might reach 3mm at the thickest around the board, and 1.5 mm by the corners where the coins are. With rounded edges it would be a really slick card.
The NFC antenna is real easy to break. Be careful when applying heat and lifting board out. Anybody got any ideas on how to encase the board and battery side by side. I'm thinking just soak into an epoxy card
So I’ve been testing this setup since I came across this video and based on this setup my batteries lasted way less than the AirTag I did not cracked open
Would be really be nice if Apple actually built in Airtag tech… not just basic, less reliable “Find My”. They are more than capable of designing that. Stronger magnets, and Magsafe in general for my wallet… (eh) I don’t really care for. I’m a bit more old fashioned having phone, wallet, and keys separate. I want simplicity and to be a little more minimal, without it becoming an inconvenience. I NEED my ID, 2 bank card, and space for 2 more maybe (for like gun permit and insurance or something). And for 60 bucks, it’s not something I’ll want to use occasionally.
