Apple Find My Card tracker, only 2.4mm thin (AirTag card alternative)

thingiverse

AirTag is too thick and expensive and I will probably never use the precise location thing. You can buy certified Apple Find My like Chipolo, Eufy,… There also Find My cards like Chipolo Card, Eufy SmartTrack Card, Pebblebee Card or Rolling Square Aircard, they are all expensive Except the Pebblebee, none of these cards can be recharged again, they go to trash and need to be replaced after 2 years So I've created a case for a cheap compatible Find My tracker that is thinner than the original case Card is the exact size of a credit card and only 2.35-2.40 mm (Two credit cards) What you need: - A smart tracker like this one (Smart Tag, many names but you need exact one like in the link) - A soldering iron - A Piezo speaker of 20mm if you'd like to keep the speaker (https://www.aliexpress.com/item/1005004471717348.html) - A CR2016 coin cell battery (Half the battery life of a CR2032 but only 1.6mm thin) - Thin wires - A NFC tag if you want to stick one inside the case and program it like a business card You can reuse the Piezo speaker inside the SmartTag case, it will be less loud than the 20mm one You can configure the tracker before or after wiring in the Apple Find My app, check manual of SmartTag The case can be dissembled easily by using a screwdriver into the holes where the pins are I have no ideas how the battery life hold up but the CR2016 are inexpensive and easy to buy Apple and Find My are trademarks of Apple Inc., registered in the U.S. and other countries and regions.
