Nice sound...

can you post the VCO / audio circuit? Thanks.

[ivconic]

As I mentioned at the beginning; I cannot publish any of the documentation I have, because I promised the person who gave it to me.
But even so; I still don't have a complete and correct schematic.
I have a schematic that is full of errors (probably intentional). And it's basically useless.
And as for the audio stage, it is based on a 4046 PLL circuit, nothing special,
I think there are similar schematics and projects here on the forum that look a lot like this audio stage.

Hi Ivconic,

thanks for the hint on the 4046... Then I know what kind of circuit it might be.

You can use polones with vco added to make a fake pulse star ii

Hello, I hope you are well. Could you send me the Pulse Star 2 schematic if possible?

[soylu]

hello ivconic

[ivconic]

Not possible.

1) I don't have correct and accurate schematic, all I have is schematic with lot of errors.
2) Even so, I got that schematic from a friend who asked me not to share further.

Hello, my dear friend, you have probably succeeded in building Pulse Star 2. Can you do me a big favor and email me the files for building this circuit? I live in Iran, and unfortunately Iran is also embargoed and it is difficult for me to I will pay you money as a gift for this project, I hope I can repay your kindness, thank you. [email protected]

Have you read previous post? Don't push ivica, orbit refuse to reveal we can't ask further.

Hi,
no doubt, the Pulse Star II is a nice project. But what is there so special? Is there a metal discrimination built-in?

there is especial board just doing the discrimination like you connect the board to DP and got DP II with the disc, for example.
LEDs in a meter FERROUS & N-FERROUS display the disc by color. simple indication.
a schematic of the board you can seek in the Archive.

If looking for PI discrim project called a-pulse is already here but don’t know if it working or not
