there is not a big difference what you take for shielding, +12 or -12. but in PI schematics GND line is +12 (look Carl's article about Hammerhead, for example). in Deepers the shield of cable and falsepanels are connected to +12 too - look attentionally on schematic of Alexismex http://www.geotech1.com/forums/showt...hlight=deepers

GND is CLEARLY +12V, no doubts.

hello kt315 and thank hi the information . at what point you need in armor the pcb can with suggestions

Dear amel
-rang 25cm use 4x8tu
-Small coil used to detect Small size of metal like Coins.

Hi amel

j.

more nice jap
but if i want to make 25 cm coil what is the change
and size of metal can detect

[jap]

cat 5

Hi amel
for Calculations the program Coil_Calculator your coil give 1.174mh.
try -19cm,0.5mm,37tu ,1.645mh.
-********40cm,0.5mm,24tu=cat 5 (3x8tu) , 1.737mh very good********

thanks Jap
can help me if my wire 0.4 mm
what turn & diameter?
what this is mean cat 5 (3x8tu)?

hi kt 315. why +12 at armor and not -12 l do not understand

apocalypto,

I have to do WITHOUT MISTAKES. it takes much time.
sorry for a delay. I have to solder King Cobra PCB back. People ask about coil tuning but without working board that is impossible. I am bursted between DP and Cobra in one hand is the PCB soldering, in another DP board in P-CAD.

good luck!

Hi amel
What are the size , specifications of your coil?--
j.

0.5mm & 31 turn &19 cm result 450 u h and 2.5 ohm

Over voltage maybe? Or wrong polarity?

thanks
yes may be that occur with me
but the resistanc of my coil is 2.5 ohm it is acceptable?
sorry i cant understand your video what is this language ?

[apocalypto]

can you write what the board sizes would be optimal in your opinion? what box you are planning to use? what mounting dimensions would be good in your opinion?

please post the new PCB

will test soon with (TLE 2082 AC ) i believe to laboratory correctly..
