hi WM6
Since I see that you have much experience, I ask for advice which made the detector to find metal 50x50 1m deep. Looked would Pohorje-Slovenija. Schematik should not be too difficult.

Hi misko,

at this time does not come to my mind something better than to buy Surf PI kit from silverdog:

Hello hakan.
Please for details of the coil. What is the U6 (LM10?)

LM10, was an Op-Amp made by National Semiconductor.
Probably Discontinued now.

And yes, misko, I forgot on very good Chemelec PI design and his PI kits (if still on stock?).

You can read more here on forum or visit Chemelec site for details.

Hi misko.
Yes it's an OP from National Semiconductor, I believe that even Linear manufactures it. I chose it because it is of the Rail to Rail OP. The need for voltage output should reach down to almost zero. I chose LM10 because I had it, but it works probably with someone else OP if you do not have requirements on the voltage output, otherwise, there are plenty of Rail to Rail OP on the market. The coils are rectangular and have dimensions 1110x630mm. 15 turns of 0.5 mm diameter wire. 715uH. The coils are placed at intervals of 3 to 4.5 meters. In January, I can probably put out a picture of this monster here on the forum.

Hi Hakan
I just drew PCB. I will first try with a smaller coil 38cm 154 turns. I hope that you will be able to penetrate into such depth. Thanks for the information.

hi WM6
I am already waiting on the shipment of silverdog.

Great Hakan. Interesting.

Are you in search for Atlantida?

yes but I do not know where to start.

Hi misko
Remember that it is not fully developed yet. I make adjustments frequently.
It could be a problem for you with your PCB. I'm currently working with a voltage control to the transmitter.

hi HAKAN
Thanks for the information. I will wait for the construction of tx. Please signals when they succeed.

hi hakan
I wonder whether the finished detector work.

[Hakan]

Hej misko.
Jag kommer att testa flera olika mottagare under Februari för jag är inte riktigt nöjd med dem.
