P.I. Long range Detector

Excellent idea!

No it's not a LRL I know that.
Still being a PI design it's either motion, non-motion or both. Wondering which one is it planned to work with?

Looking at the schematic, it appears to be non-motion. Also, it would need to be non-motion with a 1mx1m coil.

Is this a non-motion design?

This thread was started almost exactly 9 years ago.

It's an old PI design with a 1mx1m coil frame, that is claimed to be deep.
It is not an LRL as the title suggests. If you are interested in LRLs, then please go to www.longrangelocators.com, as we no longer discuss these devices in this forum.

A blast from the past, project looks dead,
as pointed out, I have made the CA3140 output to show as pin 6, c24 looks fixed.
Fixed pin 6 on right side 4538 should have been pin 16 to Gnd.
My only interest in this schematic is the integrator.

pcb nın kaynak cizim dosyasını kaybettıgımden duzeltmelerı yapamamıstım.tekrardan pdf indirdim cizmeye karar verdım.pcb de bulunan hatalar veya bazı kısımlarında yapılmasını öngördugunuz modıfıyeler var ise bana bıldırmenızı rıca ederım. erolunal , humhum tercume konusunda yardımcı olun lutfen.

And now??? What happend with this project??
Is this circuit and PCB work???

And one more thing. The diagrams are the differences, the transistor VT7 otherwise connected. Which is correct? What the transistor is there to do? It is a stabilizer?

A few bugs. Instead of 7805 and 7905 use the 78L05 and 79L05. OP 5 foot 3 must connect to GND, CA3140 output is 6 rather than 1, cd4538 (right side) exit 6 shorted to GND. CD4011 power supply must convert, at 555 key compact R13 and R9. I mentioned what I found in red, is perhaps even more bugs.[IMG][img=http://img44.imageshack.us/img44/6724/pcbr.th.jpg][/IMG]
