IDX-PRO+VDI

[Ruben2000]

Hi Ruben, it's no secret instead of Ne 5534 I put the TL071 bought at digikey, I don't trust the opam on the net, if you have had problems try to write what the problem is. Anyway my IDX is a red pcb bought from the silver dog. before welding the components I check them one by one looking for the right capacities and resistance of the same value. My IDX is already powerful on its own, with this replacement I had a gain of 10/15% more. If you have not been as successful as poor sensitivity replacing the reception opam you would not have much success. you need to fix the problem with Idx first and then you can try to make changes. Put the photos and tell me what's the problem with your IDX.

I'm sorry dgm, I disarmed my IDX PRO since I couldn't find any solution; That's why I asked you to post your PCB and the schematic you followed so I could reassemble it later. I found several IDX PRO schematics but none worked for me. I asked for help in the forum about my problem and you can see it in this link. https://www.geotech1.com/forums/show...317#post291317

Hi good morning everyone, I wanted to inform you that IDX Pro in addition to being powerful on its own, I was able to increase its range from 3 to 7 cm depending on the metal of which the target is made (coin or ring). I just changed the Ne5534 with another opam, which was found to be more sensitive, leaving the other functions of the metal detector unchanged. I specify that I did the tests in the air, and not in the ground.
I had the same result with another metal detector I built, Tesoro eldorado.

Hello dgm!! I built IDX PRO and was unsuccessful. Could you post your PCB and the schematic you use? If you use another Opam besides the NE5534, you should at least write the Opam.

The input OPA has less effect on sensitivity than the channel OPA . Put a non-fake LMC6484 (to the channels) and LM393A ( in the comparator)... you will be happy

coil

hello friends, I did the project, but there is a constant beeping sound, no response. I made the coil as follows.

Does that work for you?

Thank you very much bro, this is what I wanted

Thank you Ruben, you're very kind to check my work and make the corrections, I appreciate it! I will alter my drawing and collect the parts to start building. Take care Ruben, Regards, Marty.

I need the list of total components in word format if possible if not pdf

Does that work for you?

[Ruben2000]

Hi Marty, thanks for the greeting!
I have seen two union points that you are missing here I send you an image.

This generator does not start well with low resistance TX coils. To eliminate this, it is necessary to reduce the resistance of the resistor R3 to 24k

[MartyJ1963]

Hiya Ruben, Hope you are well! Could you please check my Coil generator PCB drawing please? I did it according to the schematic you posted earlier in the thread and I would like to make it so I would just like a second pair of eyes to check my work before I build it, Lol. Thanks Ruben, Regards, Marty.
