... I think just pin 7 of u4 (4066B) should go to +4.5V with a jumper...

Excuse me I correct my purpose was -4.5 V.

Who is the size of the file ? If it is smaller than 250kb then try to rename it.

the size is 174 Kb, and tried every thing; renaming .. and other trickes, didn't work.
Ecxact now, my EE friend called and told he has input frequency up to 4N35 and after that has no output to 555 he has done every thing. He told there is a point or problem and has no info of 4N35 features. If you lead us what should have done will be appreciated.

Try a resistor (10k..47k) from pin6 (4N35) to -4.5v.
Good luck

4n35

:confused:
There should not be any problem with 4N35...It is ordinary optocoupler, nothing else...
Pin 6 should stay not connected...
If op-amp is o.k. it should supply proper signal through resistor to 4N35 input...
But you have to be sure that proper power supply is applied, pay attention:
4N35 need 9V not 4.5 for p.s.
I didnt have any problem with it from the start...
Check again whole....must be some mistake...

Hi. Thank you guys for your paying attention, but my friend disclaimed about 4.5 V and told up to now have been using
9 V directly from a generator with optimum amp.
Oh, as he is very busy and dislikes internet never links to, I found 4N35 datasheet by goolge search and faxed for him he told:
" now I got it"
of course he guessed one of the resistors should be deleted or changed he assured me will improve it. I will post every promotion.

About Ivconic statements; "I understood this Zahori thing more or less like experiment but not seriously at all. At the end it showed as very usefull when man want to locate some power lines in walls, some AC leakage etc....or in educational purposes. I like it very much,cose it works very "sharp" and clean....But at the end....it can not detect/locate any type,kind of metal in the ground or in the air.....so far....I do not know..."

I think it's a good sign and progression, confirms it can detect hot places. As not only me but also others who have found very old buried objects have experienced that these kind of objects are completely different from fresh targets and even one conventional detector (e.g. PI) behaves thoroughly different in comparison with fresh targets. they dodge hunters and play with device.
for this reason here we name fresh targets as dead and very old buried as live objects. I think this is just for the field around them ( or other thing in that place) that all high-experienced ( Dell, Damassio,...) talk about.
Esteban is sure if there is any very old(especially big) buried objects, Zahori will beeps. and this can be the basis mineoro works.
Esteban is a nice man that we can hardly find in world. every time I needed he helped me and answered at once.
I think there is no reason Esteban to lie us that he has found some objects by mineoro.
If I complete this project I will take both devices to my very hot zones wherever are free of any manmade fields. and at least perceive that what is doing mineoro. please keep your leadings here. Regards.

Continue.


It is possible that op-amp u used is providing weak output signal to 4N35, in that case you should correct resistor value.
About Esteban...I agree. Athough i am such a big sceptic in long range locating, i can not aprove oposite yet...Fact is that it never worked in my hands so far. Maybe one day....who knows?

Hi Michael. What about *.pcb file. Please can you sent it to me with email ??
Regards

[michael]

Hi. yes and I sent it to your e-mail (gvrond@excite.com). as I wrote in page 3 don't forget to change the jumper place in pin7 of U4 IC.

Oh...

Hi Michael. I took it. Protel 99SE file ??? Oh.. very very good . Congratulation
Thanks
Best Regards

[michael]

Yes, and sent one for Ivconic (ivconic@yahoo.com). As I asked before please write your opinions and if has any problem or during mounting the board encountered to specific point state it. Regards.

Ok Michael. I will write you my opinion when i will construct it. Maybe next month when i will finish the Anker SS60.

Hi Michael
could you please send me schematic and pcb files ,too.
I want to keep it in my library.
okantex2000@yahoo.com

[michael]

Okantex, I sent *.pcb file for you, but the schematic is in my PC at work. tomorrow morning will send it. Please give your notes and opinions about. If need to any notice &... it will be appreciated.

Negative or Positive Ions ??

Esteban,
You seen to be the expert on all this zahori testing and Minero. Are the ions off the ore/metal/gold sites negative or positive ions?

Or is there some combination or interaction on the ions that would help us made a detection?

I have built several ion detectors, tested them in the field, and have found various places that emit negative ions (probably electrons) and some of the ion fields seem to pulse ions.

Any light you could shed on this perplexing subject would be appreciated.

Good THing 2 U,

Hi guys, last night my EE friend called me and said come here I have nearly finished the project.
I immediately went to his workshop just saw a mounted PCB without any antenna or box, but working very good; inspite of various exist fields, when we passed a coin over the board it would give a distinct beep. in my opinion
it can do something.
He told me " honesty at first I didn't think it's able to detect such clear and well."
Then he added " we should make some little changes in PCB and make the latest board, but by the time this can work"
It's supposed to take it at weekend after putting in box.
as you see changes is made in white ellipses (moved S3 place, link pin1 U5 to -9V, link jumper pin7 to -9v and thickened +9v & GND tracks.

Circuit Response

Hi Michael,
Are you sure the circuit response was due to the coin or maybe you were electrostatically charged and that would certainly affect the circuit and make it respond since the circuit is basically an electrostatic detector.
