Pretty cool but why does it have to be limited to AirTag or any specific devices? It would be easy to expand it to keep track of any nearby Bluetooth device and a corresponding whitelist. (Or do AirTag devices rotate Bluetooth MACs?)
Airtags are just one implementation of a Bluetooth transmitter and a long life battery but anyone could probably build a similar device dedicated to tracking with off the shelf parts.
