ELYAPIMI PLL DEDECTOR

[ivconic]

Thanks Ivconic,

Did you change things in your schematic,becose you are confuse about some things.

How big is your pcb?

Grt Nakky

No.
So far nothing changed from schematic i posted earlier.
I had doubts about pullups at audio buffer, but later turned as it is alright.
I had no intentions to share my pcb here... because of many reasons...
But now you reminded me, my friend Nakky, that there are (thanks to God) also many nice people here!
And because of You and your kind i will always share my work here.
Here it is and you can see dimensions:


(Very Best Regards to You and ApBerg, my dear friends!)

So you are not disappear for nothing last days ivconic. Congratulations on good work.

No, it is not because of that.
I had other responsibilities... too much!

Thanks!
I am like resident evil: never actually leave!

Anyway; pcb is approx. 12x9cm.
Can be even smaller if planned as 2 layer.
Lot of vias can be placed closely if it was planned as two layer pcb.
But as always, i am mostly focused on single layer pcb's and when drawing; i do pay attention of what can troubles me later.
So i always try to predict what is the most suitable for me later when soldering components.
It is too early to talk about this, but if this turns to be good project; we can rearrange pcb in two layers further and make it much smaller.
So far it's sizes are acceptable... for the enclosure i have!

Also i used 8k2 instead 7k9 and 120 ohms instead 110 ohms.
Later if i find as necessary; i will try to correct those values.

R2=1k9 and R3=7k9 in your circuit
but original R2=33k and R3=1k9.
Which correct.

Which correct.

I am not sure. Will see when i make proper coil.

I looked at this schematic earlier today and noticed this error. The pre-amp seems to be an attenuator rather than an amplifier.

Yes, thank you.

And what has happened to the 39k resistors connected in series with 104 capacitors, between the CD4007s and opamp + inputs? They are shown in the original PCB but not in any of the schematics. (See galaksi's post #33)

Instead of having only 0.1uF to ground, this started as 39k in series with 0.1uF, to ground on pin-3 of the opamps. That is not some trivial issue, imho.

edit: No, the 39k resistors are not in series with 0.1 capacitors. Three 39k resistors should be located between the opamp non-inverting inputs, and CD4007 4&11.

[porkluvr]

Here is another view of something missing. The PCB clip is from post #1.

I have severely edited the following:

39k resistors should be connected between CD4007 4&11 to the opamps pin-3.

[ivconic]

Yeah there are differences, that's because few different versions floating around.
I took the first i saw and use it to redraw schematic. (attachment)
To know which one of those is most accurate i should make proper coil first.
Anyway, considering those differences and your remarks; i found it as amazing how this detector even performing right now!?
Yet; it is working very promising even now.
But first things comes first: must make proper coil!
Cheers!

Oh man!?
GIVE US A BREAK MAN!
Learn Bulgarian if you so desperately want to know what man said!
You can't so blindly insist on forum rules all the time!
Rules are ok, but give us a break for a while!




Lately... listing new threads; man can see more warnings like this one ... than valuable and contributive posts overall!

I was pointed, er directed, to a Turkish website, but I never could find a suitable schematic to match the #1PCB, so I am still wondering WHERE did this come from??

I downloaded and installed Diptrace for the sole reason of opening one of cnckecgo's depositfiles contribution (what a lovely experience), but I was disappointed with what I did not find. The Diptrace PCB is nice to see, but providing a schematic to look at would have made so much good sense. (Hint hint).

Ivconic's (and also Eduardo's) schematics do follow the basic PCB layout (thanks to both of you) but there are some er, questionable deviations, and some disagreement on component values.

Where is concensus? Or am I hoping in vain (oh yeah, that's it.)

We get a PCB layout, no explanation, and no schematic to accompany it?
Here it is, not even April, and I'm already up to my ears in a bull$hit-arama.
