@Pustareka,,,,Thanks for the files and the link. Do you know where I can find a Parts list please? I would like to have a try at building this. Thanks. Marty

Hate to burst your bubble this is not a pin pointer it is an AC finder. I speak Italian its to test walls before you drill a hole.

@Dom44,,,,Thanks for letting me know. Would you know of any working Pinpointer projects that I could try? Really would appreciate it,,,Thanks, Marty

Yes it works decent.

You can buy Malysh as (all ready soldered, inclusive 5cm coil,
what you need more is housing) kit from this Bulgarian guy:

Link is not working. Try this one. https://newhobby.eu/en/metal-detectors/33-pinpointer-with-discrimination.html
Just ordered but will be delivered to me only march, so then will share the experience.

@Nonkapo,,,,Thanks, but the link is not working also. I have already made the Malysh FM2. It worked great at first but then only the LED's worked when there was detection,,no sound,,,don't know why? I tried several different chips,,both pic12f675 and the pic12f629,,it would give sound and LED's at first then only LED'S. I'm still trying to figure out why. Thanks. Marty

I built a pin pointer using Teemos' circuit.

My Pinpointer:

Using a Bigger Diameter Ferrite Rod will Increase Detection Distance, But than Pin Pointing Isn't as Precise.

Thanks for the video Gary,but i cant see the schematics on your site(nothing with jfets at least). Is it new project?

It works for me in the middle east. Try another browser.

No Longer Updating my Website.
And Possibly Shut it Down in the near future.

Hiya Chemelec....Would you have a copy of the pcb for the Pin pointer 4-E please. Thanks. Marty

[chemelec]

I Tried to Upload this Layout, But it says it is Too Big of a File.
Even tried Re-Sizing it Much Smaller.
It was Created in Sprint 6.0.

[chemelec]

Marty, Hope This Works

@Chemelec,,,,Thanks for the pcb image,,you're a star. I'll trace over it in Sprint and give it a try,,,I'll have to order some tantalums though cos' I don't think I have any 1u5,,,,Sorry to ask, but do you have an image of the silk screen? Much appreciated. Regards. Marty
