PIM-2 Digital Metal Detector Project

[jap]

Hi hamma
-Bad coil,,,,,,bad cable.
-for good coil use adsl cat6,cat5 original cable good specifications,,,35cm, 3x8 turns with cat5 or cat6. Resistance is 3-4 ohm.
-R5=680/3~5W---
-R16=2.2/ 5w ---
-D12=BYV28-200 OR (short)
-D4=LF356

I ordered and I'm waiting.
i used a strap, also i m looking to dissipate some heat to protect irf, i tested byv26a, is different 200v-400v, 3,5A-1A.
What is the best current for pim2? i tested from 12v/ 4A to 26A, (still same heat).

you can use a strap instead of this diode

You can get byv28 off ebay

thank you jap PIM-2 is easier than delta3 that requires a lot of adjustment
only ATMEGA are not available near my home
god bless you
I rather realize the IDX-VDI

hi all
please is there a version of PIM-2 with microcontroller from Microship as PIC16F877 or PIC18F252 or PIC18F2520
thanks

Hi ouiarabe
Yes,, but have not for publication!!!!! - but BIM2 it used controller type ATMEGA8 is better and faster than PIC type .
-With the observation that BIM2 the best version OF dp to now.
-If you want to use the controller of PIC type,Went to work DELTA PULSE 3,The two are similar.
-Note that DP3 takes more than work of BIM2.
-Both present and the choice for you.

Hi to all
i can't find 2r2 5w and byv28(200v) also 1% resistances, i try it 2r7 5w and 5% resistances with byv26b(400v) and without byv.
with small coil for test (2.2ohm) and large (32cm 24tu 7.2ohm) and other small coil for test (17ohm).
by all the way, i got (2r7 + irf) very hot, and doesn't detect anything.
wen use large resistance (17) it takes more time to become hot.
but it doesn't become hot without coil, i think that means damp resistance is good?
i don't think 1% tolerance have relation with heat at 2r2, isn't for sensitivity ? in that event ill try to get it work first.
do you think cause i replaced 2r2 with 2r7?
any body help please. thanks
sorry for bad English

THANKS jap.. believe to better explain this piece.Starts and learn about c the best result

HELLO JAP CAN YOU KNOW IF MY EXPLANATIONS HOW TO MEASURE TL062 D3Β 7 PIN Meaning HOW DOES THE MEASUREMENT The MICROCONTROLLERS. I know from having only moderate 0 THE 1 .

Hi g.s
This part has pin 24 of the most important parties because the way is converted reference Alanloj to Digital signal can be seen on the screen as they are comparable and 23 and this party is obtained on the separation of minerals
-Pin 24 is Way is converted signal(Weak signal) anlog to Digital,
has an analog reference voltage,which the analog input is compared. The digital output word can be seen on LCD (S2).
-Pin 23 like 24 but (Strong signal).
I hope I explained.

I had the Vali REVERSE r53 with r54 think now is better ,This must be the signal

Hi g.s
-its (Weak signal)

hello jap I have a question, so how we measure time changes DECOMPOSITION pin 24
