You must be using a translation software because I'm still not certain what you want. As long as you are happy, that's what counts.

It's all about that moment when metal that hasn't seen the light of day for generations frees itself from the soil and presents itself to me.

Hi MR.GD
       At the beginning of the topic desired reaction. reached 2
1- from ram  positive Reply .
2- from smity negative Reply.
3-the other read-only, and I requested them not to respond to the lack of familiarity    with. 
 after the beginning of the implementation of the project and you know hardly analysis of the design and knowledge of every part of the and Outivth Is it true or just draw an imaginary, and here you're waiting for any reaction from interested in studying ,This does not prevent the suspension of the assistant when you discover a mistake,
until the wait for results.

I'm glad you and expected you to input a professional response.
best time
j.

Japanese, your grammar is not making it clear. All I can get from this is that you want more people to like what you are doing.

The answer to that is to wait until it is finished. When it is a working model, others will comment.

O.K.......... spent ages trawling thru' that link.
Seems that someone has built a prototype discriminating P.I. that they reckon is better than the delta pulse etc......
Looks from that link they are hoping to sell it commercially.
Just having had a quick look at the schematic..... I see nothing new there.
Stick with what's proven to work and save yourself a whole load of heartache..

Yes, I went through it too and determined that nobody really has a working model yet. As a work in progress, there's not much new there at all.

Hi MR.GD
        Yes, all what you said is true, and I respect and response at the completion of the project will put some more information and results, and that which is concerned by the reaction .
 
I will start work on the initial draft of mock cartoons for easy change Because there  were some errors were corrected.

Thank you for your interest.

 Hi paul A
  Your words are as true for the other site and the project owner.
  Thanks for the comment.
best time to all

Hi all
      You should notice that there is a Board (as photo) is (the sound , delay,                discrimination for metal).I do not need a part for discrimination it reduces the         distance.
      And I will try in the existing ,The main Board of missing parts to it, and I             will add more to the audio portion of a key to adjust.
      Errors are not deliberate mistakes On receiving the result of the presence of            other complementary to the Board and will be the amendment it.

best time

hi all
      Block diag.2011

Timer:(4017+ 1/2 4069) generate signal from 90hz to 150hz .

Power :to coil(tip2955):that control the TR to the coil to produce ele. magnatic field                       (tx). the tx reflected on the serface on the target (RX).

Receiving:Rx recived by NE5534 and amp.

Delay:(1/2 4069) make delay in time between tx-rx.

AMP:(lm324-4066 -ca3140E) there are two inputs are Amplified , compared and swished.

OUT: py sound (555),VU (meter).

After explanation all parts of the block diagram by esay way that appear the important
      part after timer part is AMP part . it consistes of alot of ops & resistances confirm the amplefecation factor to each op by exact value of each resistance
      we get good signal used in 5 stges amplefecations .
    each op has 2 resistance calculate the out amp.
best time

Japanese,

To anyone who has the desire to try to improve on a design, I say GO FOR IT! When everyone gives up, the outcome for sure is that it cannot be done! Even if while trying to make an improvement, you learn that indeed it cannot be done, you still may have discovered something else that will improve the existing design.

...Just my 2 cents.

Cheers!
