AD711/AD712 are improved TL0x1/TL0x2 and they perform nice in all circuits tested and these are expensive too so that's a nice trash bin dig.
Who says gold can be found only on the field??
BTW found a 100$ Roman coin the other day just walking in the forest, near the road.

anyone finish it?
any reports yet?

Patience, it takes a while to get all the pieces together.
I ordered the LF357 in China.

Yes.
Here you do not get so easy electronic waste and 5 euros for a LF357 I just do not want to pay
Or I do not build this circuit and give away my board

where are you?
i was able to buy it in Melbourne ~$7AU
I will not know if it's ok until I build the detector

I live in Germany.
I already get the LF357, it just takes time.

[ivconic]

No progress yet!?
No videos?

[Andi68]

There is nothing new for me yet

At this point in time I am not convinced the power supply virtual earth system works properly,
I have built it but very uneven + and - voltages from 062 opamp

anybody good at spice ?

[6666]

It appears I had a new fake or faulty TL062, I now have these voltages
pin3 plus 7.82v
between pins 8-4, 8.8v
between pins 1-8, 4.3v
between pins 1-4, 4.5v

The total conductor is "+" . Measurements are made to it.
