Polish Pi

[Andi68]

What's your problem?There are versions of this circuit that work."4066 replaces bf245" what nonsense

[ZOUjiarui]

No, the 4066 improvements work perfectly, I've seen videos, more than one.
I don't want to discuss bf245 and 4066 now. What I want to do now is to copy this business in China 5196:6103.

[Andi68]

It seems you know very little about electronics.Who would like to discuss that?

[ZOUjiarui]

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

[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]

The most critical 4046 section contains most of the questions.

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

[ZOUjiarui]

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

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.

[ZOUjiarui]

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

[ZOUjiarui]

It sounds great with 4046 added.

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

[ZOUjiarui]

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