## AI overview

The author explores the idea of sensing magnetic fields through a wearable device instead of an invasive finger implant. They describe building a simple Arduino-based device with a magnetometer and buzzer to detect magnetic field fluctuations.

## Source excerpt

Am I a cyborg now? Some time ago I've read about a guy that had a magnet implanted in the pinky finger. The author seems to have made the implant mostly for fun only later he discovered that it sometimes "ticks" in and gives a "sixth sense": When people discuss magnet implants giving a "sixth sense," this is what they're talking about. I was working retail at the time, and I believe the first thing I noticed was the vibrations from the fan inside the cash register.
