Hi, I cut the red wire and the parasite is still there.

[abdou2014]

now i remove the IC in the right , the magnetic circuit works, I don't know if the removed part is essential to capture the phenomenon???

[abdou2014]

I think the IC on the right is part of an electrical receiver with ferrite, preamp and amplifier, it is associated with the resonator stimulator , I think it's the heart of the device ,

Above the post, in your photo there is such a powerful toggle switch, what role does it play?

[abdou2014]

I think it is to connect the stimulator signal with the magnetic receiver , I haven't put all the pieces of the puzzle together yet.

What puzzle are you writing about if you have a device on hand. The heart of the device is a generator (capacitive three point Colpitz.)

[abdou2014]

explain more , you mean the loop input , first stage colpit oscillator ?
what mean ( capacitive three point ) ?
yes the device is in my hand

The Colpitz oscillator (capacitive three-point), named after its inventor Edwin Kolpitz, is one of many electronic oscillator circuits that use a combination of an inductance (L) with a capacitance (C) to determine the frequency, also called an LC oscillator.

Thank you professor

[abdou2014]

if you insinuate that the resonance frequency is the centerpiece of the device, you are mistaken ,

Good ! Good luck with your setup then!

Thank you my friend

by removing the IC from the ferrite circuit on the image the device is very stable and the magnetic circuit works, it detects a 1.5 v battery from 1.3 meters
I need Geo's opinion, to know if the device can still capture the phenomenon without the removed part

[abdou2014]

I noticed the offset of the sensitivity adjustment point of the potentiometer one goes back, this means that the signal injected into the input of the magnetic circuit is cut

this means that the magnetic receiver is less sensitive, and that it cannot detect changes in the signal from the resonator or stimulator

Where did you get the scrap?
