Trying to calibrate my modified FG80.

Geo · #**153** 12-29-2018, 08:29 AM

Few steps to finish it.....

hi geo

very excellent job

where is the circuit no:3
can do you put a photo in front of the box

best regards

Circuit 3 is a receiver for an other lrl. I made the test and decided to use circuit1 as more sensitive.

Geo · #**156** 12-29-2018, 02:42 PM

Zakari here what there is...

hi geo
thank you very much for your effort and your information.all masters of this forum are my teacher and I have learn many things from you and esteban and franco italy and another masters of this forum

I dont know why do you change your plan ?

best regards

Hi.
I did n't change any plan.
Very simple i try to make it more powerfull.
For the time is at least 2 times more sensitive than the original FG90.

Geo · #**159** 12-29-2018, 07:22 PM

front side....

in Beep Generator stage ,when you use Piezo Tweetwr it some time will generate self false signals. this message was from Esteban before many years.

Geo · #**162** 12-30-2018, 10:33 AM

Yes, i know it.
It depended from the frequency of buzzer inner oscillator, from distance of loop etc....

hi, can we replace (electric field detector pcb) by a radio ???

I don't think.
But you are free to try everything you like....

abdou2014 · #**165** 12-31-2018, 12:41 PM

Thank you Mr Geo !

Geo · #**166** 01-01-2019, 04:17 PM

You can do it but it is not the right way...

Geo · #**167** 01-02-2019, 04:56 AM

Finally i replaced the electric field detector with a difference one because the first was not so stable. The new is very stable and has more gain.

iam_7up_gamer · #**168** 01-02-2019, 06:07 AM

with series 4 * 1n60

Geo · #**169** 01-02-2019, 12:15 PM

Every Ge diode is OK.

Geo · #**170** 01-02-2019, 07:37 PM

The construction of Mineoro clone with mods finished.
Weather don't allow to make a real field test but as i checked it at lab it has very very good sensitivity and is very stable.
Good T.H...

Yes ,good idea , also Esteban was use this method.

Geo ,you with what Antenna make test this circuit , with Stylus ant. or with Ferrite Toroidal + Loop ant. ???
Which is more Good ?

Geo · #**172** 01-03-2019, 05:53 AM

For electric field... stylus ant.
I can't test electric field pcb inside the lab, only outside.

abdou2014 · #**173** 01-03-2019, 10:38 AM

can you share us only the electric field schematic ???

hi
brother hakim this is good idea

geo can you share only electric field schematic?

hi geo
did you use a beep generator common for emf and ef detector circuits
if your answer is yes whats the value of capacitors between these circuits?
