shielding concentric

[lamoiz]

good evening everyone
Here are the test results of guitar cavity shielding paint.
20 ohm per cm with 2 layers, about 500 ohm on 1 layer_ 1 layer of graphite pencil ... 5k per cm .....

your problem you do not see silver powder in fabric graphite aerosole. silver powder is also black color like graphite and
does have very perfect conductivity.

you do not have a chance to buy it.

measure a shielded piece from a xt17000 minelab and it read600ohms at 1 inch at the full length of cardboard it read650 ohms

Hope that helps
for got to say that this is a vlf detector wether that makes a differents or not with the shielding between vlf or pi detectors

What mixture of graphite will give 1.5Kohm per square centimeter is for experimentation, if you are mixing your own.

[dbanner]

1.5Kohm per centimeter is what you want. https://www.youtube.com/watch?v=XnrStRklcUQ
look from 3.00 minutes where he says 1.5kohm per centimeter.

kt315 there is no attack .. it is just the answer to your tone and your way to get me high.
I have already
made the mix wood glue with graphite ..resultat very bad..tout the
powders of graphite do not have the same granulometry .. which plays on
the conductivity.
My initial question, in this case, what would you do .....?
what is the best resistivity for a shield .... on the forum there are all the values .. from 50 ohm to 2k .....? then does anyone have the answer?

Or maybe you could just wrap around coil for shielding.

[dbanner]

Maybe there is simple solution. Has anyone ever tried experimenting with this? It would be very easy to cut and paste if it worked.

you have to learn electrostatic fields Nature itself. its first. then you will go. your personal attack on me... i did see 1000th them here.

is it good example of ELECTROSTATIC FIELD influence or not?

[lamoiz]

i really do not like the way you talk to me kt315 .....
I find you unpleasant wish.
thank you for your advice..I already have this book.
I think we could be friends ... but only with boxing gloves. it would be with pleasure ...
please do not send messages anymore. I prefer all the other members of the forum by far. they are much more informative than you.
good night.

Good evening,
yes it is this painting .. exactly the same .. I give you the test results on a piece of cardboard as soon as possible.
tonight I did a test of conductivity with a graphite pencil 6b ... 100kohm / 1cm .. is that good? what should be the good value of conductivity?
thank you

do you need to read FAQ of the forum? why you are not able to buy and read INSIDE THE MD book?

Pencil on paper failed
zinc carbon battery on cardboard worked. for a short while. Unfortunately it corroded the tap wire
graphite powder and varnish worked
Graphite powder and PVA glue worked
Graphite powder and epoxy failed
Graphite powder and UHU failed
