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 |

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

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
