Pinpointer with discrimination "Cat-FM" on ATMega328P

[MartyJ1963]

Are the 0.33uf electrolytic capacitors? And can I use copper enamelled wire for the coil? I only have 0.18mm and 0.25mm copper enamelled wire. Thanks, Marty.

pcb revised and corrected, tested on breadboard
Sorry for the inconvenience

Thank you Void118 and Useus for this project. It would be great with a Vibro Motor added. Thank you for the Pinointer project,,,I've been looking for one for a while. Regards, Marty.

They will work,I've test It!

I mean that the pcb must be tested, I would not have made mistakes

Dear friends,

here Is new, more stable firmware for this project, If you want quick reply, you can ask me In comments on my youtube channel. all comments and suggestions are welcome

Moreover, I can add any functionality you need to my project, I mean settings, vibro motor, and any you want, this Is young project and I want to make It much better.

I didn't put the LEDs on purpose, I don't see any use in the pinpointer
i replaced the transistors of the original scheme with bc547 and bc557, they should work anyway

Thank you friend, the LED's are realy not nesasarry, they are only for fun)

interesting project, I saw that on the Russian forum you uploaded the updated firmware, would you be available to keep us updated here too, since on the other forum it is practically impossible to find the contents? thank you!

u

Of course, sure, here Is the link for new firmware, unfortunantely I don't know how to update my first post friend....

Hiya all, Is there a PCB layout for this pinpointer? Regards, Marty.

I didn't made PCB layout because It's very simple and It depends which components you have, so I think It's not big problem to make your own design.

[void118]

There doesn't seem to be any source code being offered by the designer, but I would think it could be converted quite easily.
The schematic is very simple, and it appears to be an off-resonance design.

I didn't post source code because I use CodeVisionAVR for example, other one may use IAR or KEIL uVision oe Arduino IDE..., schematic Is realy very simple and MCU measuring frequency shift, In case of copper frequency will Increase and decrease fo Iron.....

interesting project , would it work on a nano ?

Yes, It will
