Real clone Alonso-PD

[ouiarabe]

Via a video i cannot find solution, but maybe...
Unconnect C15 and connect power supply. If you have the same tic-tic on buzzer, replace buzzer with other attchment pic.
best regards

hi all
thank you very much professor ANDREAS
I executed your recommendation and it seems that the problem is solved
I'll get a real field because I do not have a test field
another question please is it normal for the PD detects all ferrous materials at 20-40 cm and 1m the LCD television
thank you

It's my pleasure can help you. About PD. Real Alonso clone can detect materials and detect a small magnet from >50 cm distance.PD for gold cannot detect materials or magnet

once again thank you very much for your help
this is the result but do not make fun of my modest presentation

Is it ok to use plastic casing for this PD? or it is necessary to use a plywood or ply-board...

I have 3d Printer. It's better and easy via this machine build everything via plactic ABS, but here i see the best choice is wood. Calibration is extreme.
I think plastic produce electrostatic phenomena. We don't need parasitic signals

Thanks a lot master Andreas,..

hi teachers andreas
I finished my PD after your help, it's true calibration is very difficult but ultimately this circuit detects all materials and unfortunately he can not discriminate
* anyway thank you for your cooperation and support.
and if you could, there he has a solution for discrimination ??
Thank you in advance
and please accept the most respectful greetings to your student

[ANDREAS]

Hi
First for all
I am not master-teacher-proffessor etc. Simple Andreas is enough
About discrimination is simple. Remove receiver coil and invert back-front. Now if start again fine null you can see you have discrimination. That's all
best regards

It's a big honor for us.,,to get a fast response from you sir (Mr. Andreas) and I'm bit follower of your project like PD,and I would like to build some of those. But I don't know which one of your best PD..,.can you give me and some other here a circuit with PCB layout?

PD pistol is not my design. First present here from morgan few years ago.
Qiaozhi finish full schematic after opinions and studies from many-many members.
I must send a thank for members j-player, esteban, Qiaozhi, Aft etc present info without secrets. This PD has a magic for me, because, few members try build it complete without results.
Morgan is the first member, build working only ferrite stage.
Men in my country Greece build the MD section without fine results.
Of course many members build complete this in their fantasy.
It was a personal challenge to finish it complete. Only one member with substantially help me and I will again send a big "thank you".
This is generally the story.
After first really experiments and full modifications a suprise for me is.. PD detect only Gold. This is a big chapter, but i cannot publish more.
The lesson is one. If you try, you can build your dreams. It's easy if you can study with open mind. Please don't forget with OPEN MIND
best regards

Ok sir thank you,..for a lot of information..,

Hi ANDREAS
Is it possible to explain more
Remove the receiver coil and reverse-back front.
