Polish Pi

[ZOUjiarui]

The same avt5196, the Indonesians modified it better, I saw two models.
One adds ground balance.
The other one not only has ground balance, but also has the function of discharging iron, and it also has the sound of treasure hunting.

I copied the drawings of 6103 from the PCB layout I found through Alibaba's Xianyu software, and I damaged their commercial interests.

I locked up the Google docs link and so far no one has sent a message to get my Google docs. This ancient and cheap pi is really a good learning machine.

The biggest difference I see between the proscan and the AVT5196 is just a 7810 voltage regulator.

whole info on 'polish similar' is in one place, in a folder ProScan_Impulsowy Wykrywacz Metali, in the archive.
i do not see a deeply sense to be back to that matter taht is better. proscan is good detector like a one to learn the electronics for the beginners,
not above. HAMMERHEAD is best, anyway. if i released Bara board so just to give to people learning base for understanding, not more.

Thank you for your answer, a good explanation.：好的

It sounds great with 4046 added.

That's right, xr71 is better than it. If I use it myself, of course I will choose xr71.

Is there supposed to be something special about this detector?
I don't understand why you're expending so much effort over a poorly drawn schematic, with no guarantee that the detector actually works.
There are plenty of other excellent PI detector projects on Geotech that are supplied with full documentation.

This circuit is the simplest and most powerful, and it is the commercial pi in China.

If my transcription is correct, the circuit is working 100 percent

Modified polones AVT 5196, 555 changed to 4046, large electrolytic capacitor added at coil position

[ZOUjiarui]

The most critical 4046 section contains most of the questions.

[ZOUjiarui]

The obvious problem with this 6103 is that there isn't any finished PCB, at least not that I've seen so far
Its 555 pin 1 should not be connected to a capacitor, and the electrolytic capacitor of the horn should be 4700.

[ZOUjiarui]

Yes, I'm not an expert. This 5196 is easy to make, and most new people will choose to make it.
