IDX-PRO+VDI

[Ropcsika]

DD coil values

TX- om? 20cm round tour?
RX- om? 20cm round tour?

made based on this

TX wire 0.70 - 33 turns - 0.587 mH - 1.6 Ohm parallel capacitor 1 mF
RX wire 0.2 - 255 turns - 35.6 mH - 90 Ohm parallel capacitor 33nF

Been looking at the VDI, and the mcp602.

is this the right one ? thanks

MCP602-I/P

[holyuser]

is this the right one ?

Yes, it is.

[6666]

Yes, it is.

Thank you

[holyuser]

Also MCP607-I/P is right, is even better.

“Display sized” PCB for VDI (16F690 version), standard components

I was finished the 690VDI project. How can I setup it? The IDX work good, but the VDI donn't present well. All of the metals take a +16 value.

Somebody can tell it, that what kind of sign is needed get with an oscilloscope it X and Y on dots?
Works for somebody with 16F690 PIC built VDI?

It's working!!!!!!!!

I'm wery happy!

I have a mistake on pcb. A short circuit took shape in the course of the etching caused the trouble! He came undone. I revise it another time the pcb, before solder the components

Hi Eduardo, reading through here,,,

You mentioned ..

I finally tried the IDX-PRO with the DD coil 27cm and is really incredible. 1€ coin to 60cm in the air.

Im curious to see what this is in the ground.

Has anybody done this?

Steve,

I think.. it's unlikely that even half of that is usable. My experience is that is becomes unstable mechanically at higher sensitivity settings.. even with a stock White's coil. Plus, the ground will surely be a limiting factor. I will say this though - with careful tuning , the depth is right up there with my Nautilus!

Another observation - the IDX hits harder on high conductors as compared to say, the TGSL at 14.5kHz.

Undergrund 30-35cm, in normal field. Highly mineralized ground, the depth down to about 25cm.

Im going to try the IDX and make a 27DD for it.

Let me see if I can get this one going.

Are all the pots lined up so you know which way to wire them.

I have about 5 questions I dont know the answer to!!

IDX kit build - queries

Please have a go at these questions so I can get this finished.. Steve

The circuit has been revised, and therefore agree not match pcb circuit diagram.

VR3 are used to the fine adjust angle of this delay and thereby enable a RX signal sampling at different times to the first two low pass filters of U3.

P5 is the sens-pot (with switch)

u2, u3 are replaced by new parts have been

c23: 3n9 is correct
