Magnum on steroids!

[Altair]

I personally miss Ivconic in the forum and I would like to see him again here.
Does not it seem to you that thanks to him go the forums of IB detectors. Currently all activity is focused on off topic topics and PI detectors. In PI detectors, there is an increasing interest in the topics of elementary detectors - Pirate and if even more elementary.
This wicked development of topics in the forum can not currently be overcome by administrators and moderators. People like Ivconic are needed, who are able to develop a subject and constantly keep their interest with new ideas and answers to questions.
There are many knowledgeable members in the forum, but neither of them shares their ideas openly, just as Ivconik does.

Toros,
I am totally agree with you!

My boards, a photo with the device.
It works - little different chip and a few bug fixes







My coils

[Nandor]

Great job! they look awesome have luck with it!

[Koala]

Very professional build. Great job.

Like your selection of coils.

what bug fixes were need. The information will help others.

Good evening! There was a problem with the device. Discrimination does not work. If you turn the handle by 20 percent, copper is cut out. This occurs only at a high frequency (18 kHz)

Great job, what coil shell you use for your coils? From where you found it?

In Ukraine there is a choice of forms for coils )

Check the zener diode for 4053 and 358 microchips.
Which capacitor is on the diskrim?

Check the zener diode for 4053 and 358 microchips.
Which capacitor is on the diskrim?

All according to this scheme
Please show in the diagram what I need to check
Thank you so much
P.S.

This diode?

[Toros]

vlambers - little different chip and a few bug fixes

Would you share what bugs you found in the schemе?

[vlambers]

Not so simple.
To begin with, the device uses 3 supply voltages: 12V, 10V and 5V
And, correspondingly, everything needs to be altered.

[vlambers]

This diode?

Yes, it is this diode and from it to 4053 and beyond to 358.
The discriminator should be set to B50K.
Condenser C38 - what's it worth?

Capacitor 270 p



I have soldered 50k

[vlambers]

Do you have a device for 1 or 2 frequencies?
You can try changing the value of the capacitor, the scale will change, you can set it at 470p - see what happens.

[vlambers]

I devices operate on 3 frequency: 8 (5) -12 (10) -18kGts.
