IDX-PRO+VDI

[holyuser]

Holyuser, could you please show schematic or link for your EPIC- programmer, and version of the melabs software that will program it? I built the 16F84 programmer which is supposed to be pin compatibl, but will not work.

Schematic is in attachment, software is here: http://melabs.com/downloads/EPICBETA1107.ZIP
and this is my EPIC programmer:

The question to Еduardo...

How to progress? The device itself (MD) has been tested?

IDX-PRO

Hello comrades! Good news. The IDX-PRO works and works very well, so how it should work. The PCB is correct, no errors, everything worked the first time. Very good discrimination, good GB. The ferrite rejects completely, no false signals. I have not had time to make a coil, but a friend has lent me an original for testing and everything perfect. I replaced U1 and NE5534, U3 and LF347,D3 and 1N4148 , but reversing the polarity. I have seen that some components did not make sense to me and I deleted P4, C33 and R56. I'll post here the PCB with small changes that I made. The previous PCB is correct, but now I'll post this again that I like more. Greetings! Eduardo

The next step is a prefix (VDI)? I think get a good instrument. I wish new victories!

Sorry for the mistake. That's right.

In roots it is White's Classic III.
That's indeed pretty good and deep VLF.
Forget about White's coils for it.
Use 27cm Quicksilver coil for Fisher CZ series!
No, i am not joking!
TX cap than should be 0.33 and RX cap 0.033....
Than you will meet the real beast!
Not joking at all...

My detector reaches a 1€ coin to 45cm in the air. It's awesome. The last PCB I posted is what I have done with all the modifications and upgrades.

Not bad at all!
But you simply must try Quicksilver coil, because it can go more!

If something is true then try to probe air max black

Hello everyone.
can put the parameters of the coil construction of DD FISHER CZ, if any.
Thank you.

It is not DD, it is coplanar,"concentric..."

Don't have my old notes right now.. but as i remember TX= 3.1 ohms and RX=30.5 ohms... Inductances i can't remember..
