Pulse Star II (first analog version)

[algan]

This topic continues to spread like gossip, but between the two of you I can't see how this helps the topic. It's clear that you'll never understand among yourselves who's doing what and why, and everyone is right in their own way.

Orbit,
I can only conclude one thing from your post; that this is all one big unfortunate misunderstanding.
And mistakes made by me and you too, because we remained vague in our communication.
What you wrote in the last post is probably correct.
I can confirm that only the part related to me is correct.
Yes, you gave me those files. I'm not denying that. Thank you for that.
Later you even wrote me some tips on how to make the detector work better. And that is true.
But I really did get those files a couple of years ago from a friend in Turkey.
When I got the files from you afterwards; I just wanted to compare them, check for any errors and discrepancies, that's all.
I have made 2,3 maybe 4 PS2 copies so far. I sold them at a very low price.
Because here in Serbia you cannot sell detectors in larger quantities or for higher prices.
You yourself know what the situation is here, it is very difficult, there are many detectors, there is a lot of competition.
I gave up any "business" with detectors a long time ago. I no longer consider it a serious business.
I only work on my magnetometer and occasionally I go out to meet some customers to do a small circuit for them.
I do not deny your words, what you wrote in the last post.
I was not by your side to know what happened and how it all happened.
I believe you are telling the truth.
I can only vouch for what I personally experienced.
And when I tell you that a friend from Turkey sent me those files before you; Feel free to believe me, I have no reason to lie.
I hesitated to start building that detector right away and left those files in an archive on my disk.
A few years later you and I were talking about various topics and at one point it somehow ended up as the topic of PS2.
You said that you have all the files and that you successfully made the detector.
I looked for the files for you if I would make a detector too. You gave me those files.
In addition, you gave me advice on some details.
I also built the first detector.
Many years later, I also sent a PS2 to the Chinese in a "package" of several projects.
He made it and advertised it on Aliexpress.
I didn't get a cent from that.
Whether he sold a piece or not, I don't know.
I don't know if he even made a cent from it or not.
The Chinese and I focused on the sensor and magnetometer work.
Everything else is collateral, less important and we were not too interested.
If you thought that the Chinese guy and I got rich selling PS2 on Aliexpress... you're wrong, I personally didn't get a single cent from it.
Nor did I ask the Chinese any questions about it. Because I wasn't interested in that.
Part of your story is true and I confirm. I cannot confirm other parts of your story because it is about your collaborations with other people and I had no insight into that.
I do not question what you wrote.
Why do you question what I keep repeating; that I got those files from a Turk a few years before you sent me some files?
What's the problem?
Am I lying?
Why would I lie?
What is the point of lying?
Lying will not bring me any benefit or money.
And even if there was a chance for me to earn something from it; I wouldn't lie.
For God's sake, I'm an old man, I'm 60 years old!
I don't care about such things anymore.
Orbit, I will repeat, you visited me as a friend, we talked for a couple of hours, I understood you as a very good, smart and hardworking person.
And when you left me, I had very good impressions of you.
And we continued to correspond via Viber a couple of years later.
In the best order.
You suddenly got angry when you saw a PS2 on Aliexpress!?
Why?
Then why didn't you ask me personally via Viber why and how it happened?
Instead, you wrote a lot of angry things about me here on the forum. I was taken aback and astonished.
I don't see the slightest reason for quarrels, insults, threats.
I'm just sorry that you got angry at a time when we started working together well.
I had plans with you too. I had plans for us to work on some things together.
But you got angry and just turned me off.
I think you got it all wrong and it's a misunderstanding.
Understand one thing; it's not just you, nor just me, someone who is trying to copy and clone some device.
There are a million of them in the world.
I have more PS2 documentation.
I have a more accurate schematic and pcb as well as an SMD version of the pcb.
I got that from my good friend from Bulgaria.
But out of respect for him and without his permission; I will never publish it or give it to anyone.
I have 54Gb of various works on the archive disk.
Over 50% of it is the work of other people. None of this has been published.
If I ever want to publish any of it; I WILL FIRST seek permission from whoever gave it to me.
I have the same attitude towards you.
If I ever want to give something to someone or make it public, and I got it from you; I will ask your permission first.
Of course, that won't happen. Especially after such experiences.
And also for the reason that I have long since left the story about the production of metal detectors.
Because that job doesn't pay here in Serbia.
And my additional experiences with a man from China tell me that I will probably never accept such arrangements again.
Orbit, you are too "quick" in anger and in making decisions.
Sometimes you have to stop and think.
Sometimes life plays tricks on us.
Sometimes incredible coincidences happen that can create unnecessary problems like this.
I am no longer a person who wants problems or causes problems for others.
I turned to a completely different life.
I come to the forum out of habit. I like to help people. I like to share with people.
KT315 and I have had a "million" fights so far.
But I posted pcbs and sch mostly because of him. Because I see that he has a great desire to have that information.
And he waited too long. And the PS2 is no longer a "hot" project, it no longer matters to anyone and is no longer a "commercial" thing.
I didn't post this to harm you, anger you, provoke you... no, I only posted this because of KT315. He waited too long.

How can you not see???
If there had not been this unfortunate misunderstanding between Orbit and me; PS2 documentation would never be posted on the forum!
Or at least not so soon.
The forum got the complete PS2 documentation just because Orbit and I had a argue.

Adjust delay better.

If it's on "1" then it is no wonder.
Check it on "2", "3", "4"...

You should take off your watch and try it with your other hand.

[ivconic]

I read again your post Orbit.
My sight is not that good, so I skipped some lines, now with glasses I can read better.
Orbit, there are ~80 milion Turks in Turkey.
The man from Turkey you colaborate with; doesn't need to be the same man who sent me the files.
I don't know who is who. It is usuall thing such info to leaks all over the local forums, what do I know?
Anything is possible. Many times pople give a word that "this is hot, nobody have it"... and day after I see the same all over the forums.
So I don't know how the man who sent me the files got them at all.
But when I saw that files are not done completelly neat; I simply hesitate to start working on detector. I put it aside and almost forgot it.
Until you mentioned it in our conversation much later.
That's the truth, believe it or not.
Why would I lie?
It is too banal thing to lie about.

thank you much for the files Ivconic. and no thanks Orbit. you sure know - I do not do aliens projects boards to sell.

The Pulse Star 2 has no ground balance and would not work well on ore. It would be better to develop the topic of improving the detector in this regard, I suppose, then maybe the discrimination would work in a more correct way. I have not tested its discrimination yet.

yup, I see you are beginner...you do not see that other people sure see.
the concept is to decrease of number of "krutilki" to minimum. Delta Pulse have them much and everybody is always in indignation asking what is "the pot does".
you CAN delete SECOND STROBE DELAY pot from DP too. either, you can add SECOND STROBE DELAY pot in PSII.
I had changed all names of the pots to clear understanding into kitchen wife level. so pot POWER is not now POWER - DEPTH.
FIRST STROBE DELAY is DISC. SECOND STROBE DELAY is GEB.
BTW, DEPTH is really TX PULSE WIDTH.



you can do what you want to do.

Here the test is with the right hand without a clock, delay mode 2

I don't know what's going on. My detectors didn't behave like that.

If someday I have the opportunity to have the original Pulse Star 2, I would do tests with a 28-coil so that the colleagues who make the board know what to expect and how the original works.

If someday I have the opportunity to have the original Pulse Star 2, I would do tests with a 28-coil so that the colleagues who make the board know what to expect and how the original works.

The original pro Pulse Star 28-inch coffee box with a diameter of 10cm detects a maximum of 110cm - 120cm, a military helmet 140cm, I have it written and 1 Roman denar how much it detects, I don't remember by heart, I compared the pulse old and the pulse old pro last year with 27cm, they have exactly the same depth of detection and exactly the same discrimination as one makes a mistake, so does the other. I have had a Puls Star 2 Pro for three years with a coil of 45cm or 28 inches where there is a lot of iron waste, it is impossible to work, that's why I decided to sell it. It is better to work with it in reality with either a smaller coil from 25cm to 27cm or with a 1x1 meter, the hardest I could control it on polluted ground with that medium coil.It is very important which cable you use, the original cable from the coil to the device is silicone rg 58, it is also important which wire you use, it affects the stability of the device. I almost tried the cable with protection from the outside, but not the rg 58, which disturbed the stability and moved the first sample to 17us. Next, I believe that many do not have instructions in the manual, there are some not insignificant things about the settings, it is also stated that the discrimination only works for objects larger than 10x10cm, although I know from experience that it makes mistakes even then. It would be best if you download the instructions and read it regarding the rejection of minerals or red brick, it is actually artificial because then it reduces the depth, it is recommended that if a brick is detected, you move close to the coil at the distance at which the operator holds the coil during the search and when we have moved closer to the brick, then press the reset button, the device will remember that and will no longer detect the brick, unfortunately it loses depth when set this way. Or if there are disturbances from interference, take a small nail or some metal on which the device gives a weak signal, hold the reset and thus the range is reduced, but the interference is eliminated.

really I do not know a coil size and target size PSII gives sure discrimination. when i repaired the detector i used just small coil with ferrite core for testing, in video you see it, but disc mode worked fine.

If someday I have the opportunity to have the original Pulse Star 2, I would do tests with a 28-coil so that the colleagues who make the board know what to expect and how the original works.

I bought my first Pulse Star 2 Pro sometime in the early 2000s.
I sold it to a local friend sometime around 2008 if I'm not mistaken.
A friend still keeps it and uses it.
I had coils 45cm and 2x2m.
Only later, a couple of years later, I heard that before the "Pro" version there was a regular "2" version, analog, without a processor.
The "Pro" version has a couple of flaws. It is unstable, often giving vague silent and unstable signals.
Even then I realized that I don't have much use from its "Discrimination".
But that is why it is exceptional as a "depth" detector. Of course, on targets of medium and larger size and mass.
The method of working with the PS2 (and Pro) versions is such that you achieve "stability" by raising the coil a little higher than the surface of the ground (the same as several Lorenz models that I later had the opportunity to use).
PS2 is not used for detecting individual coins and smaller finds.
PS2 is only used for rough locating of larger targets, at greater depths.
My brother-in-law successfully discovered a pair of gold earrings from the Roman period with the Lorenz DeepMax (he later bought it), but due to the enormous instability, he carried a 45cm coil at a height of 50cm from the ground!
Lorenz DeepMax is even worse and more unstable than PS2. Because it has a much stronger output stage.
It is very difficult to get it to work calmly and quietly. Usually you tune the Lorenz so that it emits a constant quieter sound and monitor the changes in sound that will be caused by the presence of an object in the ground.
Today, after so many years, we see that even the most modern Minelab PI detectors work similarly.
Why am I writing all this and mentioned Lorenz and Minelab?
Because these descriptions are a good guide for handling with PS2 as well.
Many years later when I made a couple of PS2 diys, I deliberately left out the "Disc" pcb for the reason that that accessory is absolutely unnecessary under the conditions described.
Today we have modern VLF I/B detectors to help us discriminate. And PS2, like most "deep" PIs, only serves us for deep targets. At such depths that discrimination will not work reliably anyway.
In your video you show how your PS2 reacts to ceramics, that's to be expected. Because the ceramic is very close to the coil. In realistic sarching conditions, this will not happen so often.
The coil will be at least 30cm from the ground. And the response of ceramic will always be much weaker than the response of metal.
That's the price you pay with a detector that doesn't have the optional GEB.
In other words; if you expect "miracles" from PS2, you are wasting your time.
The PS2 is a project from the '90s.
Quite backward and with many flaws.
Still usable but with the prior knowledge described above.
I posted these pictures on the forum many years ago as well:
(I tried to find the old threads on the forum but I didn't succeed.
Carl can answer this, has the forum suffered any losses in the meantime, has the forum database been damaged or disappeared, etc.
Because many of my threads and hundreds of pictures that I once posted are now impossible to find.
This is a very bad situation because you cannot give reliable irrefutable proof to the claims of who had what when, knew and gave it as material evidence.)
