LOOKING FOR GOLDSCAN 4 Schematic.

[Toros]

Any one can give me Gerber files?

Go to page 41, message 602. There is .lay file from which you can extract gerber.

Im looking for gs5

Hi Laith,

If you are looking for GS5 files, why do you not read those forum posts? Everything and much more info is there as well. You only need to read the forum posts.
It seems that you are the kind of person who want everything presented on a silver plate....but this will not work.

Who tells you that i didn't read all posts why you so angry

Hi,

you can see it how you post your requests...
You haven't read the posts, apparently. Otherwise, you wouldn't be asking about the files. Everything you're looking for is there. If you had read them, you would have found it and wouldn't need to ask.

I'll say it again: I've read many posts on this forum, but I have my reasons for requesting the files here in a single post. Not everyone is a Nikola Tesla; I'm like everyone else, looking for a good metal detector to build. There's no need to get angry; you could have helped.

Hello, I finally received all my components and have reached this stage of the build. Could someone help me with the adjustments for V1 through V5? Do I need an oscilloscope to set them correctly?

[GeoMax]

Good luck… But I don't think it will work the way you're imagining, with people explaining how to adjust all the potentiometers. Judging by the board's appearance, it seems like you've simply populated it and are now asking how to "adjust" it. That's not the right way to do it. You have to populate and test the circuit module by module. Only proceed with the next module if it's working. An oscilloscope is absolutely essential.

Initially, you can leave the trimpots in the noon position. After operation, perform fine adjustments using an oscilloscope, setting the frequency range using VR2.VR1 is the 0V adjustment for the oscilloscope probe connected to the TP pin.

Your op-amp negative feedback copper spacing—what is it?
If the spacing is not reasonable, parasitic capacitance can form and cause oscillation.

Hi Geotech11,

what spacing do you think is reasonable to avoid parasitic capacitance? 10mil, 15mil or even more?

Thanks for your help.
I’ll replace C2, C3, C5, and C10 with tantalum capacitors. Then I’ll finish building the circuit, and if everything works, I’ll try to learn how to use my oscilloscope to adjust VR1 and VR2 properly.
