ELYAPIMI PLL DEDECTOR

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

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

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.

Ivconic,thanks you verry much,don't leave use, stay on the forum.Grt Nakky

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!

[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!

[ivconic]

Thanks Ivconic,

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

How big is your pcb?

With improper coil i almost get good results considering air distances!
For a coin i get almost 35cm!!
Large iron even more.
But of course i don't get proper phase behavior.
With this coil frequency is 13.91kHz.
All the trimmers are working.
By now i put only trimmers on pcb to prevent much mess on my workbench.
Later i intend to add potentiometers.
I had troubles with some component values, for example capacitors 564 (560nF).
So i used 220nF + 330nF in parallel.
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.

So far i am pretty satisfied because i think that there are no mistakes in my schematic and pcb.

Pretty rare case!

[ivconic]

Oh yes, i made it recently.
First i had to draw again schematic on "my way" to be able to draw my own pcb without mistakes.
Than i draw my own pcb, because i don't like original one; it is too largeeeeee!
Than i made it.
I don't have time to make proper coil for it, for now, so i just tested it with Tesoro coil (Tejon).
It is working! Of course; it is not working good at all, because of the not so proper coil.
But point is; it is alive and kicking.
Also it is promising.
Will have to wait for some spare time to make proper coil.
Cheers!

Outstanding, thank you smity.

Porkluvr, feet, this project grow from here http://www.teknolojiekibi.com/yeni/i...0&topic=3810.0

I get the feeling that somebody is holding something back. To start this thread cnckecgo posted link to a PCB layout for this ELYAPIMI PLL detector, but without any accompanying schematic. Then within only a few hours, Ivconic had a schematic posted, which almost agrees with the cnckecgo post (but with some omissions and also a few modifications).

Eduardo had another slightly different version ready the next day. How does this happen so fast?

Where did this project originally start? It would be very helpful if somebody who is "in the know" would share the source of this inspiration.

thanks...

[zipzip]

seems to be a nice detector how much deep can it go ?
