An enclosure to use a modified Apple Airtag and a LM2596 voltage reducer as a no subscription vehicle tracker. The printed enclosure is held together using two cable ties. The same cable ties can be used to secure the tracker to a harness out of sight. E.g. behind dash. Wire to constant Battery power.

PLEASE use a inline fuse with NO more then a 3 or 5amp rating.

Tutorials about modifying Airtags can be found everywhere online but I found this reverse engineering page helpful

LM2596 can be found just about anywhere online
