Simple Russian PI detector Pirat

Its russian thats the problem , i cant speak russian.
I think i gonna try the circuit with the 1000uF capacitor , because i dont have the russian ic.
I need to replace the 22K pot with two 10k and the transistors with C548B and C558B hope it works.

The one with the smaller board seems to be stronger to me in the videos.

Hello, can i use IRFP450A instead of IRF740?

And im a little bit confused because there are two schematics, one with this russian ic and one with TL072 which is just the half of the russian one.
I have heard that i can use LM358 for it , i also have one TL082CP, can i use this together with my IRFP450A?

I have two Schematics one for each , which one is better? 8Pin or 14 Pin
I think i have to use the 8 Pin version but the 14 pin looks easier.

Nice, that you solve, your "lack of technology" hunting problems.

i suggested from begin to build bara or surf, but if people want simplest they get simplest.
with no perfomance. BTW while bara board is throughhole mountaing its size is so small
that everybody can make good pinpointer on its base. only must to decrease PULSE WIDTH for batt economic.

this layout works, tested some month ago
but Performance is poor
better build a simeple Version from surf pi or baracuda pi
ten times better

[bernte_one]

maybe this is last layout i could find

Hi! Simple Russian PI detector Pirat (Impad)

1. IC 157УД2 , It works the best !! 157УД2 no analogue ,it is very difficult to find .I have a few pieces for sale 157УД2.

Thank you so much quiaozhi..i will get one from silverdog..

Yes sir, the gerber file.

You can download this freeware Gerber viewer (GerberLogix) for Windows -> http://www.easylogix.de/products_detail.php?prog_id=1
or Gerbv for Linux -> http://gerbv.sourceforge.net/

However, please note that the PCB is double-sided with plated-through holes, and has a ground plane on the bottom layer. Therefore it will be very difficult to make this board at home. I would strongly suggest that you purchase a PCB from www.silverdog.co.uk
Either that, or you will need to redo the layout as single-sided using a different PCB package.
