Apple Airtag Car Tracker Case

Apple Airtag Vehicle Tracker (no battery needed)

Apple Airtag is a tracking device that can advertise its GPS coordinates on the Apple "Find My" app. It does this by pinging off other nearby Apple devices using BLE (bluetooth low energy) which in turn advertise its location over the telecommunications network.

The problem is the tag has a battery life of approx 1 year. This is all well and good for tracking the likes of keys, handbags and similar, as the battery is easily replaced. However I wanted a solution where I can hide this far under the dashboard and not bother having to replace the batteries annually.

This solution simply uses a small buck converter to dial down voltage from your cars 12V to the Airtags 3V. Fairly simple, but it does require some hacking of the Airtag and soldering. Note: you have to be SUPER careful soldering! There is a very fine wire around the positive terminal that feeds the BLE aerial. Take extra care when soldering!!! If you're happy l
