I think the chips markings are blank by the manifacturer too, so efen if you recognize them its not 100% accurate unless you have the device. Uncapsulate the chips and read the markings/structure of the die itself. You can easily recognize the 555 timer the dual op amp and the single op amps by their power supply connections. The big 16 pin chips im not too sure about. Must be some similar to cd4538, 74hc221 i guess.

It's alot of work to turn this into readable schematic, and even way more in working device so I get that, no one here is to blame beheaving badly.

first of all well done eclipse, dont pay much attention to that other guy as we say here "he is only blowing bubbles anyway".
secondly, this thread is a prime example why no info should be given without info being posted, dont come here asking for infomation on devices and indeed then get upset as none was forthcoming, you have contributed nothing infact you even blanked out chip part numbers on photos.
you simply want to copy a device for your own ends, you want us to help you but you wont even give us the correct info to be able to help you how messed up is that?

R55 is 22K - yes, not 33K.

But R64 is 220K (marked on the original picture as R55/220K).

[eclipse]

Yes that's just the bottom board.






The top board with the power & mosfet & preamp I haven't tried yet.
Thanks for the R2 & transistors info.

hi
in your circuit not to exist , sound driver(2 ic) , mosfet driver(3 tr and 1 mosfet and 1 ziner diod) , power supply (3 ic) , selector driver (2 ic), analog meter driver(2 ic)
q1 and q5 is 2n3906
r2 not assemble in original board
R55 and R64 is 22K not 33K

Added one missing link and slightly more readable.

Here is the schematic. Here and there some missing connections needed to be sorted.
It still needs to be checked for errors, simplify the connections with net ports, etc... and aloooot of cleaning up, probably best to split into sections.

"Mystery Chips":
* IC1-IC18
* Q1-Q5
* R2 - ?? unknown value

I've started drawing the schematic for one of the boards (the more complex one). It's coming along nicely.
I will publish the schematic later today, if I'm lucky. I hope forum people will step in to make a discussion.

[eclipse]

I believe you didn't get help is nothing personal.
Probably no one else has tried to built this board because of the complexity.

mee60 you might get good advice on the schematic, there are many smart people here, just give some material to think of.
So far lots of PCB pictures and no electrical schematic we've seen. There might be errors which are hard to find out alone.

hi
im finished the lorenz lp 5 circuit alone. and someone in here not help me .
reading my old post .
i have very problem but alone to finish all problem.
but so i have one problem i dont no original lorenz coil , i need a original parameters lorenz coil (uH and Ohm)
i used 400Uh , 2 Ohm 45 and 35 cm mono coil , its good and not problem but i think a original parameters is beater . or pic of one the lorenz coil opened cover is very good.

Well done.
Are planning to share the schematic with this forum?

hi all
i can make lorenz puls 5 of on the original electrical board.
this work is very hard because all part number ( ic and transistor and diod and ... ) was clear.
very difficult drawing circuit schematic because there 2 electronic board and was bilateral . but i succeeded draw schematic .
so over the schematic i got part number and i got Op-Amp number with accounts.
so i make new pcb designing wihh altium software and make pcb and assemble part .
im happy
my project is true .yes.my metal detector (( lorenz LP5)) is worked.

when my project to end in next level
i to obtain pulse time with oscilloscope for example i to understand mosfet pulse wait and mosfet pulse frequency so to obtain delay pulse and delay pulse wait and other pulse ..
so i make this pulse with atxmega64au micro controller and use ads1232 analog to digital converter .
very good projects
i am successful.
yes
in reality in next level i make lorenz deep max
im happy

I'm fairly certain that no-one here has that information.

orbit has... but orbit is difficult on stand up
