Need this circuit printed circuit board

Hi Watanabe
Congratulations success
-for Surf PI or Barracuda ,I expect results equal to.
-pcb should reflects,So it took from you a great effort in installation.

Hi Freddy67
I wish you success Also - thinking a lot before start if you mean Tarsos vlf,Suggested TGSL that completed,all information about pcb, coil available.

Hello Freddy67

I made a mistake and printed the layout (solder side) reversed ... but only realized when welding ... so I decided to weld anyway . Integrated circuits and some other components were the same solder side ...

What is "tarsi"??

Hi Jap and Watanabe

Tarsos detector can be found here: http://www.geotech1.com/forums/showthread.php?t=14595
Pi is finished and is working. Are only the casing.

Best time.

Jap, you are in what country?

Thank you Freddy67 and Jap

When constructing the body of the metal detector, I will show some pictures.

Thank you all.

Hi Watanabe

Watching the video, I thought a plumbing course with electronic anti limestone but it is indeed a detector .

Very good job .

For my part, I used a crutch
I realized the "tarsos" but the comments confirm the result ( good )
I started Cesar and I hope there will be better results.

Hello friends.
Here some more videos on my metal detector "Polish-PI".
It works well, but does not discriminate metals, so I just finding much "junk".
I intended to ride the "PI-SURF", but as this does not detect metals do not know if I'll ride it.

Anyone have any suggestions detector with discrimination??

Thank you all.

Hi Watanabe

Very good job and nice family.
I feel that my detector is more sensitive. I'm picking my car for more than 2 m and a knife like yours more than 40 cm. But this is a PI and discrimination, I just built the Caesar but have some problems with settings. It is easy and cheap to make and the results seen on Youtube are excellent.

yes. King Cobra. I have ordered second bunch of PCBs and will inform the forum as soon as its will arrived. you are on right way now.

Hello freddy67
You're right. The sensitivity of my detector is very low.
I guess because I used 'TIP41 (T1). Perhaps if replaced by a MOS-FET transistor, improves. I'll check that later.


Have a link (URL internet) for this "Caesar"?


kt315
I will inform about "king cobra"


Thank you friends.


Best regards.

For the output transistor I tried with TIP 31 and the results were good. Rather, I think a problem head.
