Delta Pulse

[aojieage]

I am also a 4538 10 feet without pulse output, your problem solved?

Hello Nicolas, a ring as I show in the photo it detects about 35 cms. No I have a gold nugget, so I can not give you other information. The coil is too large to detect small things, besides this detector is configured to be very sensitive to small nuggets.

Hi dear thank you for answering you are entirely right

Cordially

for thy KT 315 I consider that you are GOOD with known the metal dedector and (DELTA PULSE ))..
I want to do in YOU some questions For the operation of schematic D.P..
I have several questions , How does it work THIS detectors..because I am not professional ELECTRONIC , I just want to know why this is my hobby.
Well, it would be good A detailed analysis here,If you have time physical..
1 ) The first thing you want to know is Which is the role of the operating frequency detector ..if this is related to the penetration of the signal in the earth..
2 ) the use of pulse tx if it grows penetration by increasing the pulse ???
3) the role played by the emission trend of the pulse,I KNOW that most (PI) working from 600v to 1000v ,is increased the depth if the increase to volts ???..
would be nice enough to explain here ENTIRE detector..
Thanking the ante G.S
Sorry for my english IS a translation..

please read INSIDE THE METAL DETECTOR Chapter 11 and 12 and you will find all answers. http://www.geotech1.com/forums/conte...metal-detector

thanks kt 315 I just made ordering the book, I hope you will help a lot..
look forward to reached my arms now thanks again.

a question still..
to the address you gave me about the book exists and SOURCE CODE,of what the project is this ???

?What if I just pin BC546, BC557 with C546 and C557 because I can't find the transistor type BC anyone who can help me thanks

For me I use 2n3904 and 2N3906 i get same results..

for your KT315 YOU explain to me what is the frequency of operation in which the indicated the schematic ..
I have a schematic from a digital oscilloscope that counts until 5 khz square wave..
And think to customize it to DELTA FOR TO MAKE THE DISTINCTION..

I answered many times. there is some kinda interference between electric lines' and clocking signal's frequencies. this is why clocking signal freq has to be even to 50Hz or 60Hz. so this is main matter why you see in Delta Pulse a clocking signal is 100Hz for Europe and 120Hz for US. but you have THE FULL right to choice ANY frequency what you want. then do not ask me why your DP is so noisy or does not work.

?Thank you gs for your answer

?Hi kt315 I already made Board PCB elbombaci almost 90% complete just stay waiting get ic whether someone on this forum Board pcb elbombaci can work

[liekwang]

?I've finished assembling the DP Board elbombaci but no sound come out please I. What parts do I need to check

[liekwang]

?Why delta pulse elbombaci no sensitip to metal but in coil sound without the metal near the coil sound tit tit. Over and over again what should I check

hi sir kt315
my delta is very sensivity to ground, what i must to do?
thank you

Good evening FOR ALL..
you can remind me ....it goil from delta is 16 TURNS with 110 χ 110 diameter and amounts mh ?? , and amounts ohms ??..
I want to build re NEW coil I do not remember !!!..
YOU Did to help you too κτ315Thanks in advance again....
