TL12000

Hi haylaz0036

I thought you were going to post the schematic. The PCB pictures are nice to look at but are actually useless. Do you have the actual schematic for the PCB you posted? That's what people want to see.

[haylaz0036]

No, not everything is clearly. There is no connection with the contact here.

There is a connection between

I couldn't find a schematic, I printed it directly to pdf and lined it up, I couldn't find LM709, I used LM741, it works but the depth is low, most probably because of LM741.

Don't warry! The future of your knowledges will come! No body is born as professor. Go ahead.

I would use a TL071 op-amp instead of an LM741. Changing the circuit to an NE5534 would be better, but that requires some PCB modifications because the null-offset circuit is different to the TL071 and LM741. A TL071 can be substituted directly. But that is probably not your depth problem. I would suspect that the timing of your circuit is off and/or that your coil is having problems. In fact, the performance of the TL12000 is quite good. There are many videos on YouTube about the performance of the detector.

Yes, but there is no problem with the other one, everything comes out clearly

Hi all,

if you would pay attention to what is written on the schematic diagram then you would notice that the schematic is not the same as the blue colored PCB in the first place.

That's why we're waiting for Asanka Sanjeewa to post a verified board and diagram.

Sevgili Geomax, Hiçbir şey sormak istemiyorum. Uzun zamandır bu devreyi arıyordum. ATTNİY2313A-PU ile çalışan bir PCB var mı? El dedektörü yapmak istemiyorum.

Hi,

sorry, I have not seen this PCB before. But from the components it could be some kind of modified ClonePI circuit with LED output.

[GeoMax]

This can be a modified, stripped down version of this ClonePI scheme using an ATTNIY2313A-PU microcontroller. A circuit similar to the schematic below but with LED output.

There is no off topic, I worked with TL12000, it would be better if I could find 709. Did you do that with TL12000?

Dear Geomax, I don't know which project it is. TL12000 works fine, but I don't want to make a hand detector. Is there anyone who wants to liquidate it?
