For the PCB made in Sprint Layout-4.0 program click here, choose "FREE" and download it.

Gain 100-500 leads to strong ground effect.

Hello,
Well done man!
I ask you to help me because I am NEW.And nothing,BUT you post here PCB layout where the man can and do it himself!
You have a logic.
Thanks

Heh!Heh!


Heh! When man has nothing smarter to do than he is fooling arround!?
So i took housing from my broken Relic Hawk and decided to put Sasho's detector inside, also to use R.Hawk coil with it. And it is working just fine with it. Detecting onluy coloured metals, very good.
Cola can it can detect with this coil at 90cm.....No detection on iron at all.
Heh!
Here's some photos!

P.S.
I made two detectors, one for me to play with it occasionally and one for my friend....

RIP

Relic Hawk is now resting in piece....Amen!
I still have complete pcb with components, nothing missing.I just gave up of fixing it. It is available for trading if somebody interested. I cant send it by mail, abroad....So only compatriots can make offers....Also bulgarians, due they are close to my place...

[ivconic]

Mixed up...

I mixed up photos here...never mind....Also didnt take any photo of RH pcb.... If anybody interested i'll do...

Change c13 to 47nf and c10 to 470 nf. Work better.

HUH

Hi to all.

I completely forgot about this thread...
Yes the circuit works well. I just tried to run it with dead battery..
Now it works very stable - with perfect disc... just the range is somewhat shorty -> I have to make better coil as the one I tested the circuit..

Thanks to Sasho for this...

I will correct the PCB layout (one sided) and post it here.

Ivconic nice work as always .

Hello

Can you tell me can I change NE5534 whit something?
Because I cant find it!
What is Im2930-8?
And how are called this parts?

[ivconic]

....


"This part.." is multi turn trimmer potentiometer....may be replaced with ordinary....
29xx can be replaced with 7808....although better to use low-drop..
NE5534 can be replaced with LF357 or LF356....I used those instead NE5534 and those working very well...also other replacements....LM318 for example...
regards!

[Leto]

Corrected PCB (8x8cm), one jumper (+ for NE5534)
