Hi Gary,
as always very good work!
Thanks.

Hi!

I've seen MAX's BanditoII project. I think I'm gonna try to build myself
one 'cause The BanditoII with the large 10*12 coil was very well rated
in the Big Detector Test in Belgium.
If anyone has any data or description of the 10*12 coil, please send to
me or link to the forum.
Is there any special info I need to know to make a coil that almost as
good as the manufactured one.

Thanks:
Levente

this should also be correct for Deleon?

The coil connection details are incorrect. In fact, the last diagram is one that I created while trying to debug a faulty Tesoro Laser.

Here's the correct wiring:

This diagram should also be correct for my deleon coil?

Greetings,

Mentioned earlier was something about teflon wire, and what seemed some trouble obtaining. could go to your local automotive engine rebuilders store, find some tef-coat or similar, empty into cooking pot place on electric stove heat and boil your coil of wire. The copper will expand and teflon will bond to it. (just like cooking projies).

About coils, have/ has anyone tried the one or two coils (depending on model and size) located in the back of TV sets.?

And the following design coil might be something to play around with if interested.

Hi,
you can find teflon insulated copper wire already made. It's not cheapy but you don't need big volumes e.g. to make a PI coil. Teflon wire is not good for VLF coils cause you need much more inductance and so more turns, that will not suit in any case if wire is too thick.
For PI coils teflon covered wire is the best out there cause gives very low capacitance to the coil itself, so aid to reduce minimum sampling time to less than 10us (if other stuff is ok too).
TV-CRT coils are not good for VLF cause inductances are too low and shape has different role than in metal detectors(deflecting moving electrons).

Best regards,
Max

I don't know the answer to your question. Have you checked the inductance of the coils according to the diagram? Even a simple connectivity check with a multimeter can be used to determine if the connections are the same.
