Hi,
Sasho.
This looks like very interesting schematic indeed.
Can you give some details.
Like what value we shell use for DR1?
Also is 74HC4538 OK for this design?
What wire do you use for the coil.Normal copper wire like in VLF?
Thanks

Не употребявайте PI детектори. Те създават много силно електромагнитно поле.То е опасно за здравето.Може да създаде сериозни проблеми за хора с песмейкъри.

Do not use the PI detectors. They create strong electromagnetic field.To dangerous for
health.Possibly to create serious problems for people with pacemaker.

Sasho,
Please give little help here.
Now the only thing that left is the value of drossel1?
What we should use? 1mH?
Is resistor like ok there.

PCB looks rely good.Can't see mistakes.
So I will begin making this unit.Looks like good first PI to me.

20-100mh or resistor 36 om/0.5w

Thank you very much!

Hi all,

I made this PI. It works excellent and can beat my Deltapulse.
I suggest all to make it.

Many thanks to Sascho for this design,

Hi,
if so... someone will made a pcb sooner or later. I didn't made it cause have already too many PIs for my taste!

Now that I'm looking for new stuff I see that some Sasho's designs are really what I need!

So really thanks to him!

Kind regards,
Max

Zdr. Sasho!
1. Na kolko to4no balansirash izhoda na 5534 ?
2. Kakva e konsumaciata i dostata4na li e Batt 12v/1.3Ah
3. Kakvi sa vremeintervalite za diskriminacia i otkade se vzema strob
Predvaritelno blagodaria!

Thank you very much!
Except few unknown capacitators and the upper conection around NE5534/where is conected this resistor to pin 7 and 8 or just to 7?
Every thing else looks cool.
Very elegant PCB.

If anyone spot mistake please alert.

I am in the middle of collecting parts.
