Hahaha.....
Congratulation....

What do you think about 24V delta?

[Jose]

Increase the voltage in the coil to increase the current flow in it, has its advantages when it comes to getting more depth, especially in large, deep objects.
Peros 45 laps of a coil of 40 cm in diameter, I think it would have a high inductance (more 2000 uH).
This inductance value is not practical for most applications, with a relatively high delay.
I like to experiment with the reduction of laps, and more coils.
It's just my opinion.

hi

hello
I'm tired after compiling the circuit did not work there is a problem
The approach of the metal does not make any sound when you remove him and make sound
And the distance when you zoom the metal sound discretion a second time and distance does not exceed 5 cm only please I'm tired what is the solution to all of you and thank you

HI ALL

Dear Brothers,
Did not answer me one question please, I do not know what to do

The circuit works vice versa when you bring the metal does not come out and vote when you keep him out a simple sound, distance 5 cm

Is there any better than this chipset has been tested and successful
Please advise
The required depth 3 TO 4 M

THANKS FOR ALL

Hello
Try to help. How many laps has its coil, diameter, damping resistance value?

Hi

I have 2 question about DP :

1. How can change the speed of Auto tracking

2. I want to have reverse signal on vco it means when a metal approach to coil the sound decrease ! and when take it away the sound increase

Hi KT315 & all Delta Pulsers

I think response time of Delta pulse is normal and no need to change

I built 2 delta pulse with single sided pcb , both of them works the same
maybe my DPs not works good they work like motion detectors ?!!

if i place a metal near coils the signal increase rapidly then the signals fade out and the device become retune itself ( i still have the peice of metal near the coil and the signal fade out) , it's like auto tracking mode !!

first of all is it normal or my DP has a problem , any body has a video of DP when a metal object remain in a fix distance to DP coil ?

and this auto tracking make the detector response very weak on deep targets cause it's speed is very high . i built a switch between T7 and R29 for this problem but i need changing it speed not to remove auto tracking at all.

best regards

Hi Great Alex
The operation of the delta pulse is normal, as you describe.
You can try changing the value of C21 to vary the response time, I think it is better not to touch.
I try to manual mode, for continuous tone about the detected object.

Kt315, friends and experts help me, please

Knowing its knowledge in the Sniffer Xr-71… I at the outset bought to a Stilian Bulgarian the Sniffer with fuse (002383019-big.jpg) and
it worked correctly, I had an error in coil connection and threshold became unstable… It sends beeep long if I place potentiometer
after 5. It only works stable in number 3 of the potentiometer and reset does not work.
But the detection of a softdrink can Coke to 35 cms.
before the coil error in search, marked coke 90cms.
It could help to solve the problem?
Another thing, I constructed the Delta Pulse that attached…

I have reviewed everything and seems to work correctly, nevertheless, it does not exist light in no of the centers leds
nor is sound.
It could help?
Thanks for its aid.
Him desire the best thing always.
From Mexico for you, a strong hug.
Best regards

amigos

the greatest photo, of nF red is my work…
There is not no sound, illuminate leds either…
Which is the error?
I am not expert, but I am learning with you. It is my second Delta Pulse that I construct friendly Thanks for the aid

my friends, info for your's

my friendly, I want to inform that I solved to the problem of the lights leds…

but now, the green LED (remains caught and it does not go out…
green LED must be caught all along?


I changed tl 062 and lm 555… in 2 occasions.

not yet there is sound… I changed could help?


thanks to read

best regards

Heriberto

Hello Betobrambi
Green LED should light all the time.
Sound, controlled from Pin 3 of the 555 to 1K pot (volume control) and connection to the speaker.
