But building a metal detector yourself doesn’t have to be hard, as [Mirko] shows in a recent post. His STM32-based pulse induction metal detector looks good and works well, as you can see in the ...

The circuit creates an audible sound ... Usually, underwater metal detection is done using pulse-induction metal detectors, Podhrasky said. “Over the years, it’s been a constant development ...

The metal detector part of the project is fairly straightforward as far as these things go. It uses the pulse induction technique, where short pulses are fired through a coil to generate a ...
