felezjoo PI(the best pulse induction metal detector that I made until now)

[Toros]

if i do export, SL writes there are 5 holes in silk layer and thats impossible to do the file.

These 5 points, are shown in the layer S1 field, but must be in C2. This is not fixed in the file I gave to Gandolfi. Gerber files are produced from the same not fixed file. The drill data too. I do not currently have CAM350 installed and I can not check where the Chinese problem is.
I apply a new folder with fixed these 5 points and new gerber files. Open files with online gerber viewer do not indicate a problem.

[Toros]

I installed the CAM350. This is how the circuit board looks like with a professional PCB program

[Toros]

Gandolfi,
If the Chinese do not solve the problem send me your address I will make a PCB in the home and I will send it to you. It will not cost you anything.

[gandolfi]

the chinese says " Hi Sir, Thanks for your e-mail ,so sorry for that my colleague send the incorrect reason why we cancel your order . It's because there is no outline layer for your file , so we cancel your order and refund to you . Could you kindly to check your file about the outline layer ?"

How i can resolve this ?

thanks

this company takes any CAD files and does without gerbers http://wonderfulpcb.com/

Hello

a square needed around drawing for board outline

try attachment file

[gandolfi]

hi, i have send your file samii. i'm waiting the audit.

For the other file from Toros chinese says "Hi, so sorry for that we cannot make the board for you since there is no board outline in the file. Could you please fix and reupload the correct file ? Thanks~"

[gandolfi]

THANKS SAMII !!!! The pcb is approved and in production. And thanks Toros and kt315 for your help.

hello, can somebody here explain to me what LF357N does in this detector. is it an integrator or differentiator ?
and what is the master compenents to adjust it's confugiration?
best regards.

[gandolfi]

Thanks a lot !!! i have just received the pcb from china.

felezjoo pi coil

hi i need help with the coil of felezjoo pi how to make a good coil for this, thw round coil i have made 40cm 350 uh 1.5 ohm with the cable to connect is not working well.can you tell me how to make better coil like spider or any ? i check LF357N is good . thanks

[Kostasp]

test it with 3 round coils :
40cm 1 ohm 350mH DELAY +8(27) A208 B610 C744
28cm 1,3 ohm 400mH DELAY +8(22) A263 B678 C782
22CM 1,3 ohm 280mH Delay +8(19) A200 B612 C755
ANY IDEAS ?

spider 30cm 0.70 thickness 1 / 1.2 om 384uh, LF357J result will be good

[Altair]

test it with 3 round coils :
40cm 1 ohm 350mH DELAY +8(27) A208 B610 C744
28cm 1,3 ohm 400mH DELAY +8(22) A263 B678 C782
22CM 1,3 ohm 280mH Delay +8(19) A200 B612 C755
ANY IDEAS ?

Kostasp,
to obtain an increment of A value, try to increase the inductance coil's up to 600 uH.

[Kostasp]

thanks gurdal but i dont know how to make a spider coil ? if you have any direction send me.

Altair i will try 600uh but is too far from 350uh of the manufactor.
