Hello Manu ,
For the coil :
Diameter= 28 cm (11inch the best compromise rapport)
- 19 TURNS Wire caliber= 25 Awg (0.45mm)
Resistance = 2 Ohms ; Inductance only the coil =335 uH measured .
A good Dynamic searchcoil.
Have a good construction , Alexis.

hi ineed detail for 15 inch coil plz.thank u

Hello everyone

Delta Pulse works very well, can detect a soda can of 333 ml. At more than 1.40 mtrs. With coil 1X1 m. in the air.

Hi Jose

what is the specification of your coil ?

what kind of wire you are used ?

Thanks.

Hello Belief
I use flat cable 18 drivers that I provided elevator maintenance technicians, the diameter is 1 mm. approximately, the total resistance is about 2 ohm.
I use MD damping resistance of 680 ohm, in the 1x1 meter coil added two parallel 2.2 K ohm (1.1 k ohm). The operation is stable.
The scheme without modification as shown in previous posts.

400 Hz timings

Maybe I am wrong but I've not been able to find this information on this 3D.
Anybody, kindly, could post here timings for a DP working (tested) at 400 Hz? Thank you in advance.

Hello Jose

Could you give a test video ? if it is so what is different on your Delta Pulse?

Dear Erolunall
I will try to prepare a video for next week.
The soda cans as are preserved, are easy to spot as iron, remember that these are ideal conditions and with maximum profit at the controls of MD and optimal adjustment of delay time.
Do not make major changes in the circuit, use lf357 (LF356 noisy).
TX power potentiometer 20 K, I use 10 K for IRF840 not overheat the 60% (approximately 120 microseconds).
Delay time from 20 to 30 microseconds, reducing training 1.5 na 1 n if necessary, otherwise as indicated in the scheme.
Good PCBs for minimum phase noise preamps (lf357)
