Serbian pi Gold-Skan

[luci1988]

Hi Orbit, again all last night I set trimmer per channel metal works ok but the channel detects all metals gold and detection range is quite small 10cm max, I tried with a gold ring but it only detects large objects in copper or aluminum. The coil is 25cm by 21 / 0.50mm turn beside turn.

[Orbit]

On how to set the pattern for all metal channe l? Taking a sample of the lowest adjusted !

[luci1988]

I switch the channel when gold falls power metal detection and call all the same. Do not discriminate!
I switched button reset button all metals we switched and we all trimmer set to 0V compared to GND. Detection is ok for all metals!.

I use 1n60P diode (germanium) and J113 is ok?

[luci1988]

I found that when I switch on all metals TL064 voltage drops to 7.74V on exactly density 5V drops to 2.24V.
When I switch the channel voltage is 9.92V gold.
I removed all integrated circuits but nothing has changed it is ok to TL064 voltage 7.74V?
Please help !!!

No voltage should be 10 volt , something is wrong !

How do I adjust the trimmer P3 and RV8? Thanks

[Orbit]

My biggest problem is the expression in English ,because I brief you need to know how does one pi and primarily the second channel to influence ground and that discrimination sort of positive supplement a must who knows English to explain !Otherwise this project has to suffer some changes to work well . My idea was that this would be a base where to individual members gave their suggestions the project to be much better ,so I and some details left out in order to heard opinions other members dealing with more pulse detectors with rejection influence ground ,for now I see that none of it read such works Tdi -whites , so you'll understand some things about adjustment ,until you what to expect he will not be able to to adjust not an option .All the best !

Hi Orbit what is your native language ?

[luci1988]

If someone managed to complete this GS6 please help me. I do not want to give up this project and I know that has few mistakes. Thanks

[luci1988]

Hello Orbit certainly is an error or wiring diagram please help me I checked everything I measured voltage components all ok but not discrimination. Thanks.

[luci1988]

Hello, voltage 5V on pin 4 to TL064 decreases when approaching a metal coil. Can anyone tell me if it is right? Thank You

Orbit Hello, I managed to build GS6 I had a problem on the PCB, now works ok but I have a little problem coil oscillates alone or I move left and right. Any idea?

((( little problem coil oscillates alone or I move left and right. Any idea? ))) I do not understand to oscillates explain a little realistically to understand what you mean ? offices protection spool fard -cage !

Hello Luci 1988. You say you have found a mistake in the PCB. Could you post here in the forum where eroor was? I made the GS6 and it has worked, but not discriminated iron.
a greeting.
