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********

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]

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

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

[jap]

Hi amr muhamed
What are the problems?
j.

[amr muhamed]

i can't find the problems..... may be there are components burned.... i want to compare the output with your circuit

[jap]

Hi amr muhamed
You did not specify the problems?
How I do and I do not know?
j.

[amr muhamed]

ok....you can help me by attach some photos of the output on the oscilloscope at some points ....and if they are not the same with me ...so the problem at this point.
