Hi

where is potentiometer ground balance ?

here there is no potentiometer of ground balance ?


or I do not see him, then how is tuning out from ground?

"...R90= Audio pitch, audio frequency, also can be fixed value, according to your own preference..."

This is typo! It should be "R60= Audio pitch, audio frequency, also can be fixed value, according to your own preference..."

Here is the GEB pot.

On some Golden Mask models there is no GEB potentiometer on front panel, on some model there is.
Generally the schematic i posted applies to all models the same.
GEB potentiometer can be wired directly to pcb instead R90... OR adapted with R90 and wired in series with it.
It's up to you to decide what suits you the best.
You can adjust R90 trimmer to reject hotrocks and minerals and leave it fixed on pcb (so called "automatic ground balance") or
you can wire multiturn potentiometer on front panel to pcb with wires.
You can put only one precise multiturn... or you can use trimmer and potentiometer in series too.
Make your choice, pick any of the combinations, it is up to you and your preferences.
Here is the GEB;

Thank you very much

Mega32 is used only for sound generation

There are some inaccuracies, but I'm tired of it ((

Great job!

Is there a lay file for SMD board with numbered elements in this thread?
There is one with types/values. I guess the best option is numbered elements without values (so sneaky chinese don't copy it)

Man!
Ivkonic gave us schemes and PCB for granted, and you want to take further and numbered items specially for you.
If that is so necessary - take it himself and then post it here for our convenience.

chill out.
I respect what Ivconic did.
Read again what I have posted. I've asked if someone has already posted it, because it seems logical. I can do it myself, no problem.

[ivconic]

No i don't have it. I haven't made it.
I did only skim component placement as sort of reminded, in case i get any of those on service.
I decided not to trace out pcb draw from model 5 nor to trace schematic because it has 2 programmed chips which we can not reproduce.
The rest of circuitry is more/less ancestor from previous models with slight changes.
But now thanks to ozzy_sv we have more complete details on model 5 too.
Honestly... i had model 5 for several days on testing and didn't like it much.
From whole series i liked most model 4WD.

I built TH version. Depth is great. Depth in the ground is very good.
disc. 0 iron is removed,this is correct??

Error ? Mag redu pcb.
BG should go to pin7

[Toros]

What is the problem? See where it goes blue path / level C1 / and does it link with C2 level near 10k resistor. Levels C1 and C2 are connected in two places along the path of GB Pot

[perkun]

GB pot. is connected to pin 6 Lm324. should go to pin7.
