    I saw this one = not imprest​ , https://www.youtube.com/watch?app=de...ature=youtu.be
    Certainly the best PI detector I've built so far... this "so far" is valid as of the date this was written.
    Later I started making Pulse Star 2 which is the best PI I have made so far in its category.
    In both cases, you should pay attention to what it literally says: "which I made".
    So they are the best of those that "I made". And not from all that exist or from all that others have made.
    So; I speak for myself. And I'm talking about what I managed to do.
    It would not make sense for me to speak in general terms and to generalize things.
    Certainly there are much better PI detectors and certainly much better work by others.
    I hope that statement is clear now? Or need further clarification?
    ...
    Proof?
    For something that will cost $20-30, you should not ask for a proof.
    You sit down and make it yourself and create your own impression about it.
    Proof can be requested for something that requires more serious investment and effort, more invested time and work.
    For example "My AGD analog detector work" by Auto-Mation-Assist is a very interesting project.
    But it is very complex, it requires serious construction skills, good knowledge of the issues, but also a decent amount of money for everything needed for construction.
    In that case, I asked for a "proof", not really a real proof, but just a short video where I would see the basic features of the detector.
    Auto-Mation-Assist gave me the impression of a very serious expert in that field, I have no doubt that everything he wrote is correct, I am almost sure that everything is so.
    And it would be shameful to ask him for any "proof". If it was understood that way, then I'm sorry, it was not my intention to doubt his claims in the slightest.
    No, I just wanted to see that detector in action, if only for a few seconds, with the simplest demonstration.
    I'm a detector fan, I "fall in love" with a detector sometimes based on just a few seconds of a video.
    Vice versa; sometimes a few seconds of video demos immediately dissuade me from any further interest in that detector.
    A matter of taste. And tastes are not discussed.
    Unfortunately Auto-Mation-Assist didn't seem to see it that way and wasn't prepared to make a shorter video, so I lost all further interest.
    The same is the case with what Moodz does on another topic. It all seems very interesting and I would like to see more details about it.
    But a shorter video would say a lot more.
    Unfortunately Moodz is a typical Aussie prankster who will push these things endlessly and will not provide such a video.
    He will rather post x000 more posts with graphs, oscillograms, formulas and claims... but a simple 20 second video he won't do.
    Again, I have no reason to doubt what Moodz writes and claims. The math is clear, his words are clear and he is a man with pre-established credibility.
    So there is no "doubt" at all in my requests to add a video to the attached idea. Because video is a powerful medium and shows much more than words.
    We are not all the same, someone is an analytical mathematician, a few simulations are enough for him to understand everything.
    I am not like that. I'm a bit stupid. I visualize things when I think about them. To me, the video means and speaks much more.
    And I draw conclusions based on my 37 years of experience.
    There is little in this world on the subject of metal detectors - that I have not seen before.
    So that experience helps me analyze and understand what I see on the recorded video.
    And of course, in the end, I could always be wrong.
    The video can be recorded with a tendency to show something that is not realistic. Youtube is full of those.
    But in a good spirit and with a positive attitude, I always gladly watch every video and later draw my own conclusions.
    There, Pito, I hope I explained something to you.
    If you want to get an impression of this detector yourself; all you need is to shell out a trivially small amount of money and build that detector in a couple of hours.
    I'm sure you'll make it.

    • To all Felezjoo detector fans

      Here is my personal opinion about this detector. I think this detector is the best for you because you haven't realised that you can't modify or change much at all except maybe the case of this detector. Actually, you are probably better off buying a ready-made detector. You can't change much here either. The source code is not available for the Felezjoo, only HEX code. And only with the HEX code you cannot change or modify anything in the software functionality.
      If you like detector projects with a microcontroller, I suggest you take a closer look at other free DIY detector projects where the source code is available. These really are the best pulse detectors you can probably ever build yourself.​

      • Some things you wrote require additional explanations and comments.

        "...this detector is the best for you because you haven't realised that you can't modify or change much at all ..."

        Quite the contrary, I realized that I could not change anything significantly on that detector the FIRST day I took on the construction job.
        So later I never tried to change anything. All I tried to do was to listen to the author's advice and to bring my works as close as possible to that advice.
        I don't know where you got the idea that I ever tried to change anything on this detector?

        Next...
        "..Actually, you are probably better off buying a ready-made detector..."

        Of course! Aren't we all like that? That sentence of yours has no sense or meaning.

        Next...
        "..You can't change much here either..."

        If you mean purchased factory detectors here... you are totally wrong. I've made a whole little "career" out of it, here locally.
        I have modified, changed and adapted dozens of factory detectors.
        But that's part of the business I do, a commercial thing, I rarely or never post such things on the forums. I wouldn't want to cut the branch I'm sitting on.

        Next...
        "...The source code is not available for the Felezjoo, only HEX code. And only with the HEX code you cannot change or modify anything in the software functionality..."

        Another sentence that doesn't make any sense.
        I have been a programmer since 1982. And a professional programmer since 1991. Telling me such things, which you tell; is funny.
        I don't know who you are, but by your words and thinking, I would say that you are a young man who has a strong need to teach others. That's a good feature, keep it up!

        Next...
        "...If you like detector projects with a microcontroller, I suggest you take a closer look at other free DIY detector projects where the source code is available.
        These really are the best pulse detectors you can probably ever build yourself.​..
        "

        This is already something that makes sense and I agree.
        There are a lot of interesting projects on the forum, worthy of attention.
        After all, that's what this forum is for. To educate and give people the chance to have crazy fun in self-construction - diy.
        ...
        Hmmm... is my impression wrong or are you and Pito running some kind of spit campaign here?
        I'm much older than that.
        We did such things that are not good for the forum much earlier, 20 years ago, when most of us were confused by the new way of communicating with people and
        were very clumsy in places like this forum. Over the years, learning from the behavior of many wiser people here; I have learned to stay away from such occurrences.
        Furthermore, whenever I notice in one of your posts a tendency to provoke or write something that does not correspond to the factual situation; I will simply ignore both you and your posts.
        I have too much "mileage" to waste my time on people who are not good at forum correspondences.

        One more thing, don't be fooled by the slightly more direct and free style of expression among us older forum members.
        We have known each other for a very long time, we have been through a lot together.
        Strong forum friendships were created there. And personal contacts outside the forum. It's a long time.
        The things we refer to each other are something between us, based on years of friendship or at least being on this forum.
        You who are not of that "generation"; who only "yesterday" came here and started posting; you are not in that situation yet and your thoughts are interpreted differently.
        For example: KT315 can always call me stupid and ignorant. And me to him the same. It is our form of communication.
        And fundamentally, I consider him a friend of the forum and someone who has done a lot of good for the forum.
        And there is no misunderstanding between us.
        Carl, George, Davor, KingJL, Sinclairuser, Moodz, Altra... a dozen other people; they are free to say anything to me, and I to them.
        It is not understood in the same way as when one of you "from yesterday" tries the same thing.
        Don't fool yourself with this one. It takes time and friendships to be created in order for us to reach that level.
        Let this be my last post on those topics.
        I will ignore any further tendentious provocations.
        We have not gathered here to judge and condemn each other, but rather, I hope, we have gathered here because of our common love for metal detectors.
        He who does not realize it; that one won't last long on the forum.

        • I was just wonder which PI is the best to build.
          The video can be recorded with a tendency to show something that is not realistic. = Not realistic???

          If it's unrealistic for you, it doesn't mean it's not realistic at all, 15 years ago I sold the wireless underwater TV technology to Nature Vision (now Aqua-Vu), they said it was impossible (unrealistic), after 6 months of negotiations I had a meeting with the company's president, Jeffrey Zernov, and the technology was sold.

          • The felezjoo MD project is full of claims , but I think, it is a big mistake to mix "very powerful" with "rich of settings".
            Many possible settings only points that project is similar to HH MD at digital base. Noting new in MD capabilities.
            Sorry if my opinion is not right.

                  • gurdal I believe you mean it's a reverse-engineered hex and not the source code.

                    • Hello friends and teachers.
                      I built this metal detector and now I am facing a problem.
                      When I connect the coil and turn on the device, I encounter a coil error, and after pressing the balance button a few times, the error is removed.
                      What could be the problem? Of course, I tested with some other coils and it is the same.

                      By the way, how many turns and what thickness are needed for a 60 cm coil?

                      Should I use RG58 or RG59 cable?

                      Thankful​

                            • Hi good day !,

                              I am currently working on building this detector, but it has been very difficult to find the original LF357N. Has anyone successfully used a replacement without reducing the sensitivity of the detector? I would greatly appreciate your help, as you are a group with a lot of experience and knowledge in electronics.

                              Thank you for your help. Greetings from Colombia.​

                              • in Colombia... what can i suggest you... try to find OLDEST american trash electronics boards, seek TL081. it was used in very old TV sets and EGA VGA SVGA monitors.
                                you can use LF356 too.
