King Cobra PCB

[tuxnor]

Tesoro coil will fit..but wich one ? i see sabre will fit ?

[skool]

what size of the wire is suitable for king cobra coil ?

[kt315]

selim, too nice work. do not remember to solder all pads and pins on both sides anotherway you will get a trouble with it.

hello I made a king cobra but is not it working after the virtual is not good I have only 3v. All parts are checked out okay but I think the scheme is not a good combination.

Hi Mrand,

Nice logo! I have the detector to go with it...

I understand what you mean. I have watched your video carefully and my answer was obtained in a previous post. The XP GMPower has 3 shades, iron first tone, second tone for foil and third tone for coins. Unlike GMP, the KING COBRA has 2 tones. With the potentiometer placed at least discrimination, the iron is not detected at all. The foil is detected in the first ring and the coins are detected by the second ring. If we put a coin under a hot rock, the coin is detected in the first tone, like a foil. If we place a foil under the hot rock, the metal detector does not emit any sound. So there is no miracle. This is happening with all VLF detectors. Now I have no coil available to make another video. The coil with which I made the video, was a TGSL and not available. In the future I'll build one for the King Kobra. Greetings.

I see.
That's not bad at all.
Better to produce lower audio than not to produce it at all... like some other detectors that i know.
Instead GMKC i made Panthera which behavior is similar to what i see on your video.
But i will make GMKC too soon, i like it.
Cheers!

I downloaded those files and among them i saw Eduardo's video.
Wow, splendid work Eduardo!
Nice, neat and clean!
Now i would like to ask you something to do;
can you take mineral, stone from your video and put coin or ring on the top of it and than show detection and Cobra's behavior?
Can you?
I asked this before somewhere on this thread but i got no answer nor response.
Hopefully i am not asking too much!?
Thanks in advance!
Cheers!

all files have been reuploaded, there are new one bought the PCB's, mainly for them. 100mb. regards.

you can use 0805 type resistors (L=2mm) too. at a photo are 0805's setting on PCB.

[kt315]

yes, certainly, because 35V more than enough.

best regards

I have access to 22uf 35volt SMD 7343H caps. I can use these for all the 7343h parts?

and 22 ohm 1206 resistors
