IDX-PRO+VDI

[CDI]

Is there a SMT Version of the IDX PRO board?

And whats the difference between the silverdog board and the one here at the beginning of the thread?
Is there a partslist too, i just have the partslist for the silverdog board.

First version has the frequency shift trimmer/pot.
On the Silverdog version, 2 diode's 1n4148 are removed, according to author that version has little better discrimination. Also, first version had BD139 audio transistor, now is MPSA13/BC517.
On Silver version, phase trimmer is removed and mounted 2K7 fixed resistor.
C32 capacitor removed, that's changes what i remember from the past of thread.
General: No major changes, all version's work's very good, i personaly tried them all, deep machine, average disc.

If somebody makes PCBs from the SMD Version, then i need a board.

Thanks Toros!

Yes! There is a serbian version of PCB. I do not check and buld this PCB. You must check it!

Better ton`t connect both shields down in the head but connect each coil shield with (-) / (end) of the coil and by shielding of the cable connect to the ground on the PCB board. Оtherwise the depth will reduce by half.

thank you CDI,I will try best regards

Aluminium foil shield connection this my picture is it correct ?

Yap. Good luck on the next step.

Yes, rx - and tx -, but for idx is much better to shield coil's with graphite paint or spray and connect to -rx.

On the normal IDX -Tx isn't ground but -V so would stop the Tx from working

I found better results in wet grass if the shield is only connected at the PCB end. Original Classic schematics show it this way

Depending how you mount your board and if its in a metal case or plastic and or your connector have a metal shell or plastic as to whether its better to connect the metal shell of the connector to ground or not

thnx koala I will try rx out 200mv.

Well shield connection rx(-) or tx (-) ?

best regards

I normally aim for less than 200 mv Rx out with a scope

Don't get to hung up on it though. Aim for the smallest then check that a small piece of ferrite is rejected in all metal mode somewhere near the middle of the ground balance Pot. If not you might have to move slightly from minimum null to get the correct ground balance.

Hi friends,Where is the coil balancing setpoint ne5534 rx in or rx out ?

and,how much milivolt ? thnx

are you going to make the source available? Surely would be nice.

I'd like to port it to a different chip than the PIC16 family, as well as add a realtime counter. When going out during your lunch hour at work, I'd like to be able to set a time into the counter so when it counts down to 0, you know it is time to pack it in.....

no problem, the source code is released under the GPL license (attached below) and it compiles with MPLAB XC8. To port the code to a different PIC you would only need to change the files mcu.h and mcu.c as in the directory P690 for PIC16F690. If you use the XC8 compiler in free mode you would also need to remove some features in order not to exceed the space in the PIC and if you have a gitlab account you might access the git repository at https://gitlab.com/eserradi/VDI.git for changes in the code...
