I am an amateur electronics and I did Delta-Pulse in the file that was declared valid in this forum..PCB I did Son1.Basic indicators to show that everything is ok (amperage voltage levels ...), but not detected by metal detectors. when the search coil is closer to a large metal surface can be heard ringing frequency TX.You you said that the scheme has many mistakes and would like you to reap where they would and my detector worked.Sorry for my English langue
many thanks advense
Hi VUJO
-DP the scheme & PCB Son1 true , no mistakes .(Mistake in implementation)
---The cause ringing frequency What are the size , specifications of your coil?-- may need to change the resistance=R5 1k ~ 2.2k /1w of each suitable coil!!!!!
best time

Characteristisc of the search coil are: -250mm-diameter coil -number of turns 25 -wire diameter of 0.4mm -coil resistance of 2.5Ω -500µH inductance -Pulse frequency 400Hz -Resistor R5 of 820Ω/2W
-try to use Coil Calculator to make good coil.
-try R5 = 1K~2.2K.

It may not be the best prepared and coil,but can not be a reason not to.I think there is another implication.Montage works well,but I do not know.Do you have the correct components

Hi Vujo
It seems clear that you do not like to use the Coil Calculator!!!!!!!!!!!!, the -number of turns 25 wrong,the correct of number of turns 32tu.
-wire diameter of 0.4mm wrong,the correct wire diameter of 0.5mm.
-try R5 = 1K~2.2K.
Clear from your words that mistake in the coil, appears to be sound like the pcb good.

please KT315 , when you will post the new pcb of delta pulse ?
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?
