PIM-2 Dijital Pulse İndüksiyon Metal Dedektörü

[VECTROUM]

Pin 7.

[VECTROUM]

Also the only pulse noise is coming from coil.
Not noise to any other component!

Pin 7.

hi your board is normal  4504 wave form good ,,interesting I think about lf 356 , training ,you must similar  pulse return in atmega ,and in ırf ,,and change 4066 try ,,please , and coil R5 680 ohm try 1k try -350ohm for pulse end ,

[VECTROUM]

Thank you for your precious time.
I will make changes and inform you about the results.

Hello, i changed R5 with variable resistor 1K and the pulse on Irf740 gate pin, on lf356 output pin, on mc14504 6 & 7 pin is square wave 125Hz.
But not on Atmega, on atmega pin 23(SIGNAL) i measure only noise.

[VECTROUM]

The detector is not restarting now, its ok.
The only problem is that it not detects anything!

[VECTROUM]

No reaction to any metal.
Can you please inform me where to measure voltages?

Thank you.

hi ,
ok ı forgot so ı will write control voltage for you ok thanks

[VECTROUM]

Thank you.
Can you please tell me how many turns of 0.5mm enameled wire to use in order to make an 400mm coil in order to have the right indunstanse for this detector?

[VECTROUM]

Can please anyone help?
Bars on lcd moves when metal approach the coil but no sound come out of speaker.
Speaker work only when open pim-2.

hello ,
pim2 voltage stats ,
p1=12 volt (batary)
p2=5volt (7805 for atmega8)
p3=10.7 volt
p4=pim2 wait no sound no metal =1.35or 1.45 volt (withmetal and sound =1.88 volt
p5=pim2 wait no metal no sound =0,18 or 0,15volt (with metal and sound =0,23-0,25volt)
p6=0,07volt stabil
p9=6.05 volt stabil
  my coil 45 cm and  3.2 ohm so R680 ohm  ,,,and normal working ,
maybe you can check sound out pin of atmega and sound transistör , goodluck allthe best regards
