tx-150.tx power max-250.delay1-30to130.delay2-50-450 microsec.

Thanks

Hi again Sascho
And I have another question,
Are you have designing about LRL or long range locator ?
Best regards .

Hi Sascho
Please say me about deep of search on various type and size of metals.
Thanks a lot.

This PI is not designed by Sasho. It is an old schematic with old parts...

Not used ICL7660, MOSFET, etc.

Hi 1843
PI was invented times ago. Designing based on our knowledge
And what’s we want.
Almost ,good designing not need modern and new parts .
At the end of project ,result very important. Good designing will
Has good result.
In my opinion all of Sascho designing was very good. I meet Sascho
And his circuits in this forum and don’t know him from later .
Also I simulate some parts of his circuits with proteus software .
All of those ,working very good in mathematics area.
For example push poll oscillator from TR circuit . at the first simulated ,
And second I built it in on breadboard .
Practical result seem as simulated result ,with good stability .

Hi Sascho .
Do you remember the Tx pulse (us), the delay pulse(us) and the delay of sample1 and sample2(us).
Regards

I am not inventor of warm water.Look integrator.This is my design.Schematic work perfectly.

Hi Sasho
Please writing more about it.
Best regards .

Hi Sasho,

Have you made this PI yourself?

[aft_72005]

Hi 1843
No,I study and check circuit theory, It is correct .
We are waiting Sasho more explain .
