felezjoo PI(the best pulse induction metal detector that I made until now)

[sabios]

I'm doing some tests with the Felezjoo, but it's a version I've adjusted and I call it DW. I've also changed how it discriminates; now it can reject metals like lead, aluminum, pewter, soda bottle caps, and others, which go into the FERRO category, while copper goes into the NON-FERRO category. In theory, copper, gold, and silver should also go into the NON-FERRO category, but at the moment I don't have any high-quality silver or gold to test with, only copper.

What I did notice is that with the changes, it's able to shift the discrimination backward or forward. For example, if I move it, the aluminum can might go into NON-FERRO, but if you adjust the settings a bit, it might go into FERROUS. And that way, I can only search for valuable objects, like copper, gold, and silver. But for silver and gold, I still have to test it, but for that, I have to get them, and right now I don't have them. I can get silver, but I don't think I can get gold.

According to the tests I've run, its discrimination is based on conductivity. It's not precise, but it's capable of removing impurities and leaving precious metals like copper, gold, and silver. However, it can't differentiate between them; the discrimination only goes that far.

And in fact, while testing, the 7805 burned out, and I don't know what else happened, but it doesn't matter. I just have to fix it and continue testing. What I've noticed is that using it like this reduces the depth and stability a bit, but it's just a matter of finding the optimal configuration. As soon as I can fix it or build another one, I'll upload videos to document it.

But I want to clarify that this is a version I'm working on, and as I said, I'm calling it DW. It's still in testing, but it's progressing well.

This is the first test to demonstrate some of the discrimination capabilities of this detector.

By the way, this is a PI Metal Detector with the ability to discriminate metals by conductivity. It can be used to search only for more conductive metals like copper, gold, and silver. It's still in the testing phase, but for now, it's able to reject metals like aluminum, iron profiles, nails, rods, pewter, and other metals, which are marked as FERRO. Copper, gold, and silver are marked as NON-FERRO on the screen, making identification much easier.

I should mention that this is a modification I made to the Felezjoo, which is why I'm calling it DW, to make it even better than it already is.

The box is legendary, well done!

Ah, it just happened that way.
For the first time since 2018 (since I have 3D printers) I switched from PLA to PETG and right at the start I had huge problems with the settings in Cura.
I think I'll go back to PLA when I use up this roll of PETG.
The final box looks good, but it needed some extra work after printing.
There was a lot of "stringing" in the print and I can't seem to adjust the parameters to get rid of that problem.
I'm going back to PLA at the first opportunity!
