New FelezjooPI o PulseMaster

After a lot of testing, I’ve finally sorted out the ID issue; it took a lot of work, but I’ve finally arrived at a solid configuration.

It now features true, dynamic ground tracking as well as dynamic ground balancing—meaning, in short, that you can use the coil at any height (though holding it too high does slightly reduce depth).

It also boasts more advanced discrimination compared to the Felezjoo.
It is capable of detecting a silver coin amidst construction nails—something not many pulse induction detectors can do; I actually tried that same test with the Felezjoo, and it failed.

For now, I’m still running tests to confirm its actual detection range.

Here is a sample, but remember, it's a demo.

It’s turning out really well—thank you for your hard work. I follow the videos and tests on YouTube, but the fact that it uses a demo hex file makes me hesitant to start the project.

Check out the new video; it demonstrates the discrimination capabilities of both metal detectors: first the Felezjoo, and second the PulseMasterPI, which I built from scratch.

This is actually just a small sample, as the device features a more comprehensive discrimination mode capable of detecting a silver coin buried 5 to 10 cm deep amidst scrap metal (provided the trash density isn't extreme). In normal mode, it fails to detect the coin; it is only when using the most aggressive mode that the silver coin can be detected quite effectively among the scrap.

This is the board I use for the GT—feel free to check it out.
It works for the PulseMasterPI as well.
It has a small modification that might seem insignificant, but I tested it against the standard version; with this latest one, iron discrimination actually improves a bit.This is the board I use for the GT—feel free to check it out.

And of course, I did that because removing and reinstalling the ATmega for so many tests is difficult given the limited space in the original design.
