Bruh, is this board layout from eduardo here, still worked without update? Im already put most of the components
After i browse, most of the pcb picture have 10k trimport and 3 zener diode.... Should I continue?

Yes work as it should

Looks interesting.

This is connection for 2 tone. [ATTACH]39490[/ATTACH]

thanx
but i need to explain about VDI schematic and how it is work.
regards

hi
any body have VDI programing.(no hex file, master file)
how it is work?

about 2tone,any body can explain??

I am struggling with this constant tone problem i am having can some one please give me a idea on what i should be testing?
My u5 pins are measuring..
pin1 - .8v with swing on metal object
pin14 - .69v with swing on metal object
so i would assume the circuit is working up till that point.
Thanks.

Thanks.
I may have a bad u5 as my detector is only working in pp mode but constant full tone in dis mode..
Could some one please give me some volt readings for the u5 pins.
My Readings are as follows..
1 - 3.23v (no swing when passing metal over coil)
3 - 140MmV (large swing when passing metal over coil)
5 - 4.5mV (slight swing when passing metal over coil)
7 - 550mV (swing when passing metal over coil)

Hello
Pinpoint switch if open working in discrimination
pinpoint switch if closed works in all metals.
my problem is 100% coil fitting construction, PCB Silverdog ok.

[Daviddawe1]

Just a quick question is the pinpoint switch meant to no or nc?

Thanks CDII read the instructions for the coil, I have to build it.
I wanted to somehow verify the operation of the various stages, I worry about the non-detection in all metal and do not know if it depends on the incorrect phase shift (20 degrees).
it happens that the pin 6 U1 I measure 4volt pp targhet detects and performs discrimination mode but not detected in all mode.
if instead perfected the nulling for 400millivolt to pin6 U1 detects all metal but does not detect it discriminates so discrimination
or should one or the other goes, I read somewhere that the phase difference must be 180 degrees, is the problem?
sorry for the bad English !!

coils TX 6mH RX 6.6mH

thank you

I said 40mv. That's measured on my scope.
400 mv is too high. It can work with 400mv but with original idx coil specs, i'm not sure if can with eldorado coil, cause i never tried.
Do not waste time and nerves, it's much easier to make coil according to data posted here than making some half working Frankenstein.

Less than 100mv, my last 11" DD has now 40mv and works perfect. Coil for Eldorado is not good idea for idx, why just not make coil by specs posted many times here on forum?

Hello to all
I built idx pro pcb Silverdog no errors ok.
md it works with self-built coil Eldorado.
8khz frequency sinusoid optimized with trimmer1k (instead of R7) 16vpp.
I believe the wrong phase shift of 20 degrees because in all metal mode does not detect targhet (threshold works).
switching to discriminate mode works fine targhet detects and discriminates iron.
which must be right degrees phase shift tx-rx for IDX?
how many millivolts to pin 6 U1 after nulling coil?
I ask for help
thank you
John
