Hi hadi-dindar
-try with Coil-Calculator to make any coil .
-for dp3 400uh~500uh , 0.5~0.8 mm
-note to pot {1/2 value} in inner radius
-coil resistance 3~4 ohm

Are doing the DP3 stop to change a program such as Pasha, contact me at the same time.I will be with everyone making improved the DP3 hardware.My [email protected])

DP3 If the program does not improve, there is no way to detect high frequency.Coils require a high from the ground will not barking, coil difficult to match the pulse width is too small, so the power is too small, I do DELTA PULSE 20x20CM can detect 2.2 meters.DP3 is only 1.5 meters.DP3 does not have the advantage, I would suggest the Pasha able to change it, and the other to do a manual cleared button, automatically cleared, still a little barking, the maximum is 100 Hz frequency, high barking.

thank you jap

Hi alonejax
I did not make a flat coil for this, But I made Gary's flat coil,i will try it and tell you the result and flat coil design found in Gary site,or search for it in our website here under the name of Gary's detector

Thank's for Pasha ansver my mail

Hello everyone, I would like to increase the detection range of the DP3, I would like to improve the hardware, or can do high-precision op amp TL062 and TL082 AD family of op amps replace it

I built dp3 work with demo hex file

[algor]

I need full hex for DP3 English
Three times he sent an email to Pasha not answer

[liudengyuan]

Yes, I feel DP3 does not the Delta Pulse then the utility can not tune the frequency, pulse width can not be adjusted, not cleared button, when the case of instability, the noise is very troublesome, can not handle.So, and the coil is hard to configure
