Ok, Geo, this is all I have regarding this magnetometer.

Maybe this can help.

Hi.
Do you have more details about this schmatic? as filter frequency or pcb????

Regards

[Baterista]

but to am sure i design a new pcb for another schematic of main amplifier.

Maybe this can help.

[Baterista]

Btw... when you will try your magnetometer out to field???

I'm thinking about to risk with the traffickers, in this weekend, could not get a better place.

[Geo]

My coils are 24mH and 10 ohm.
I did not try yet the solution with electrolytic capacitor so to reduce the noise, but to am sure i design a new pcb for another schematic of main amplifier.

To obtain the specified value of L1 and L2 was necessary to change the diameter and the original length of the coil, which was
47.62 mm x 71.44 mm (The result was 16.8mH and 11.4 ohms) for 50 mm x 50 mm, when the result was 20.8 mH and 9,3 ohms.
At first I used 24 AWG and 23 AWG in the second.
23 AWG is the value nearest 24 SWG.

Hi Baterista.
Also i used other types of potcores with different permeability, so the turns are not the same as at article.
Maybe today to try the capacitor. Now i have much noise and when the volume is high there are microphone echos...
Congratulations for your project, you made very good work. I am very lazy to make so good projects: Lol:

Thanks Geo, always kind.
