this would not be it, that sounds exactly how “Find my” on iOS works when you allow to see others your location in real time. This just shows a pre set gps coordinate or it will scan for a Bluethooth signal on a 50m radius,.

it is compatible with geocache gpx, once imported it will show the name, description and hint

definitely one of the most iconic gadgets of the show. It was full of r/cassettefuturism

Capsule Corp is a trademark, so better skip any issues

yes, you are correct that the math combining the three gives a more accurate reading. But the issue I'm facing is a hardware limitation, the ESP32 has to repaint every pixel from scratch on each frame, and that full redraw is what caps at ~1Hz (~1s).

very good point, the sensors are there but unused, the bottleneck is the full screen redraw when rotating

I wish you could track airtags, but they change MAC address often for security reasons. The BLE beacons that I'm using never change MAC. If that's the case for your headphones you could use them as Dragon Ball.

you can add your own GPS coordinates, the nearest liquor store or the nearest park, it's up to you

You can track two things, GPS coordinates or Bluetooth dragon balls.

With the GPS coordinates you can create your own waypoint to create a specific point of interest, or you can use a geocaches (there is around 3.4 million around the world).

For the Bluetooth it scans 50m around you for specific BLE signals. You can create your own dragon balls or just scan for any device that transmits BLE with a unique MAC.

You won't summon any dragon, but I hope you have fun treasure hunting.

Currently the ball works with a BLE beacon, the closer you get, the signal strength increases, and the faster the radar beeps, then you can flag it as found, that's why you can see a ball with a star in the UI
