Real clone Alonso-PD
 

Hi all and Happy new year
Many members knows few years ago i build a clone Alonso-PD
This old "amateur clone" i use many-many mods for find the best balance between all stage.
But is not enough for me. Last months i start again experiments. My "target is... I try work with the same method use by Alonso for calibration omega-coils and feritte all together with standard schematic publish here from qiaozhi without any extras.
I find this method and i build a "real alonso-PD clone" with all parts.
My prototype now can detect a very-very small magnet-piece 2 meters distance very easy and a micro transmitter 433MHZ more than 50 meters distance.
My clone has not false signals from South-north magnetics lines and with calibration knob i can calibrate machine very easy in search-area
In my test-area work perfect, but i need make tests with unknown area and ofcourse video's with unknown targets
This knob for calibration and very small mods (low-bat section, power supply section) are the only extra's
The truth is that the calibration is too difficult and now i understand why there were failures to construct a truly clone
Here some pics my prototype
Heltkit section and feritte section work together without extra selection switch. Output signal from feritte coils is very-very low and feritte section now, work without overload signal.
Next days if i have free time i publish here more infos and i start video's with prototype
I want to thank a forum member here ( very good electronic engeneer ) , because, with his help and testing , I managed to find all the problems encountered
best regards

andreas excellent job. you are using ferrite and omega coil together? can see the regulator calibration for the ferrite, it changes the position of the ferrite coil?

still you fiddle with this??:lol:

Alonso Scheme for PD is the best here. Thank you to all who have actually worked on and do some modification and updating. such as Qiaozhi Eteban and Morgan and other.

Good luck my friend Andreas. and I hope for you a good result in all the world.
the transmitteur and receiver 433MHZ and the right choice my friend. well you advance in this field. 433 MHz is used in the detection by the magnetometer.

If you need help for higtech you know my email.

Your coil looks higher up than the original Alonso PD, and the ferrite appears to be placed in the null line (as described in Chapter 14 of ITMD). Is this correct?

With ferrite "out" of coil is more easy to null the signal of passive receiver. But original Alonso;s PD is different.

I use scale via photo ( for example attachment pic). In this case i have false dimensions +/-2-3 mm. After study some photo's inside PD-Alonso, before start build omega-coils etc, i am sure for results and real dimensions using my PD.
...and the ferrite appears to be placed in the null line (as described in Chapter 14 of ITMD)
I have not your book, but feritte is not placed in the null line.
Please remember my old message, we have ONLY a "magic place". In this place, output feritte-coils has only 0,1-3mv output signal. For this results, i use a micrometric moving system and ofcourse need fine null omega together (move -null omega and again). This point is very difficult. We need repeating tests, before protection this place
Regards

Does your ferrite coil have two cores with a gap (as per the original Alonso PD) or is it just one complete core?

It's same about results, the gap is easier for calibration, but
the gap produce sometimes false signals. My opinion.
Never we have see a real photo, about feritte (gap or not). I think "the gap" is false infos for stoped some members build it or present a myth
I think "original feritte" work with complete core. I use complete core, because has stability out signal
Second i believe never members open the original coil in feritte. A x-ray photo yes, but destroy the place and open never
I have this sense, because.. if you have a unit and work , you don't touch :nono: somethink and stop work.
The interest for all is this "magic point" is +/- 0.1mm. Tell me Quiaozhi, can you find this point with your hands? Personally i cannot. In this case my clone with micrometric regulator i think is better original
Conclusion. Members that say they know or have opened or know exactly how is the original, i think say "guess - tales" and they publish bla-bla and dreams.
If they knows really , few years ago, they start build and sell units. This is only real true.
regards

I was also unable to find the "magic point" by hand. The TOTeM unit uses a single ferrite core that is placed in the upper null line of the TX coil. This is easy to find by hand, and can be nulled to only a few mV.

If the original Alonso PD has a split core, then I suspect the ferrite nearest the TX coil is acting similar to the nulling coil in a concentric arrangement. Since it is not driven by the TX oscillator, and relies only on voltage induced into the coil, this would explain why it is very difficult to find the balance point.

About totem is easy, the transmitter is very low power. I don't i build complet with transmitter, only i build receiver. Alonso PD has a strong transmitter and feritte core is very near. For all places we have 50-100mv output coils feritte, ofcourse overload feritte-receiver

see what esteban said:
I forgot! See in blue circle the sand. Pistol also is used as normal MD for to found the item in the sparzed sand or hole!http://www.longrangelocators.com/for...1&d=1262613997

bobina omega é md normal ,não encontra objetos longe
only part ferrite is lrl

You have not exactly right. Need the part of MD receiver. But it is very unstable and soon i replace this stage. I see after experiments need a balance between MD receive and feritte receiver for best results
I make tests only MD section or only transmitter with ferrite, but I do not like the results.
regards

> this "magic point" is +/- 0.1mm. Tell me Quiaozhi, can you find this point with your hands? Personally i cannot. In this case my clone with micrometric regulator

This whole ultrasensitivity adjustment way described here is for laboratory only.
Its useless because if the voltage will drop from 17,995v to just 17,985v it will be already out of balance again.

Same with temperature, moisture, electronic parts and especially harsh treasure hunting
conditions like weather, electro-smog and many other factors.

Under super stable conditions you also can built an usual metal detector
that is extremly sensitive. But at real treasure-hunting everything is anything else than super-stable.


btw. it would be much more clever to fix and construct the part with the 2 coils first on a extremly solid basis (melt it into plastic or resin etc.) and afterwards you find your needed zero or whatever EM-field window for the ferrite-coil by electronical adjustable components like variable capacitors, mini-coils or whatever. If this point is so critical and easy to bring out of "center" you must work with a programmed microcontroller which controls and readjusts the needed values automatically.

A lot measurement with a 10meter rope works perfekt, but only if there is no wind at all.

You are confused. We have drop or not if unit don't work lab this is correct. In this case i have put a microcalibration pot for setup again. Please study my pics. On panel i have a calibration pot for it. If you cannot understand me my method, don't worry

I have not time for explain more. But you must be sure, if put a microcontroller this clone don't work
Funfider i build this clone for personal study and use. For me is a "pratform" for understanding method use by Alonso (if he.... build this machine). I am not interest search or find more about "Brasil method" detection for long range.
I am not interesting for sceptics if... this unit work etc etc or not
I am only happy, because after few years, i publish the first real clone.
Later if i finish my study with this unit i send this unit gift... a good friend mexico. Maybe if he want publish results with this myth. You knows, this is not my choice
For me is only a personal test for find method calibration.
My "cup" is many-many members says ".. i build it", but i am sure now, on they dreams ofcourse build it

TOTeM was constructed for similar reasons. I wanted to understand why other members were convinced the Alonso PD could detect targets at distances greater than a conventional metal detector. Then there was the technical issue concerning the ferrite coil balancing. In the end it turned out to be a very entertaining project, and the results were interesting enough to include in the book (ITMD).

On many occasions skeptics are accused of having no personal experience with LRLs, so this was also an opportunity to push that accusation to one side. All the information concerning TOTeM is provided in ITMD, and nothing is hidden or made purposely confusing. Other members here have built TOTeM, and one has even created a PCB to replace the original stripboard layout. It's an intriguing device to use in the field, and often you can appear to be following a "signal line". However, I leave it up to each experimenter to arrive at their own conclusions, and to modify the design as they wish. :nerd:

Qiaozhi If TOTeM can detect a very small magnet 5mmX5mm 2 meters distance you are a "right way" . I find this tip after many experiments with small luck.
Few months ago, i build a greek-project name english-PD. I see the same results a small magnet detect 5 meters distance and a very small 433mhz transmitter very easy detect 50 meters distance.
We have the same results. Strange is .. if we have perfect calibration and detect only small piece magnet, units cannot detect magnetics lines from earth.
I try understand more about ferrites with coils. Maybe i find a theory for this, but is not time explain more
regards

Is this a neodymium magnet that you used?

Do you have a link to this "English-PD", or perhaps you can post the information here?

Yes ... interesting observation.

No! This is a very simple small- black magnet from a chenese- toy.


This is a old cscope (maybe 950) with full modifications and a pink or purple ferrite length 20cm. This unit detect only gold fresh-buried-old on air... etc,without problem very easy. Later maybe i publish some infos about this very interesting modification, because here is a thread for clone alonso-pd
For me interesting is we have two units working with same philoshophy
regards

Hi Qiaozhi.
Look the thread "STRANGE..." at RS forum

Here is the better design PCB for this PD.
Later i publish full schematic (is same posting by Qiaozhi) and a pdf file PCB for all members wants build it for experiments. My mods are very small for stability.
If i have free time, i make some video's for look all members why i say "this is a real clone"
regards

Thanks Andreas for sharing and posting this information, and continuing with constructive elements and experiments.
This is finally neutral and technical information, whatever are the results they will be useful and interesting. :)

Yes, I agree. This detection of a small magnet at 2m is intriguing, and a video showing this in operation would be most interesting.

Thanks Geo, It looks like this might be the same device. If Andreas can post some information, we should be able to check.

It is TR950D by Cscope.

Congratulations Andreas for this new project
I hope you can find how this realy works.
Best regards
Nelson

Full schematic without transmitter (later i publish transmitter sch+pcb)
As you can see ,this is original schematic publish by Qiaozhi with very small modifications
regards

All this tinkering, discovering, helping together here concerning electronical issues is ok.

As long as the info doesn't leads us "real results wanting" persons away from the serious track. I self built and tested one of those Zahori circuits which mainly are based on electrostatic so afterwards I knew with this stuff you can find electricity lines or rubbed air-ballons from a good distance but no treasures.

I like tinkering but it was still a waste of time and ressources - just because some people here suggested this "could work".


And the same it might be with the ToTeM or the Alonso Clone....

btw. I am not a "skeptic" which condemns everything completly. First some persons here thought I would be a LRL-believer and now some may think I am a skeptic. I am also nothing in the middle, I am a realist who controls everything exactly, compares how much truth a story really could contain and I work with very fair warrants.

This world or better the own personal life will always be full of decisions and judgments of what it is good for me or others and whats not. It is not just to make their lifes hard if doctors, judges or even politicians have to study first. Complex and sophisticated things need alot background- or special-knowledge otherwise people will fail with good work or correct results.


Shure, I could start to experiment with those circuits, too, but why I should find out completly the same as we know already?
And what we know is not really convincing if it comes to real treasure-hunting.

If we see the whole thing as a development-process then it's useless to test the same stuff over and over again. But the motivation to contribute to this kind of "not really promising stuff" would return if there should popup really promising results.


Do you know what is CW? It is "continuous wave". Do you know SSB? Its Single Side Band.
Why do I ask? Because with special ham amateur radio transceivers you can hear ultrashort bandwidths of just a few Hertz thousands miles away.

It is no big deal to create ultra-sensitive detectors - its pretty simple today.
But those must work for the intended purpose.


This micro-adjustment stuff shows already clearly that we have a very ultra-sensitive receiver of some sort. And of course ultra-sensitive detectors react on minimal EM-field chances, be it a magnet or a 1.5v spark 5 meters away.

Just the question is:
For what it is really ultra-sensitive and under what stability conditions?

This here is a forum about metal detection an not radio-station-LRL-detection.
It is not about the Hubble telescope which is ultra-sensitive for super far away stars.

So the question is: How useful is this kind of supersensitive-detector for metal?
For metal buried under ground, otherwise we may find it with some field-glasses, too. ;)

Or in other words:
Its wasted time to experiment with ultra sensitive radio-receivers if those are not good for metal-detection.

I'm pretty shure the ToTeM or Alonso is some kind of BFO which only reacts on metal or magnets because the coil-activity or inductivity is extremly very slightly changing (on a level of just a part of 1 Hz, it could be even just the shape of the wave-form which gets slightly disturbed or interrupted for some time), even passivly if a huge metal object already interacts with some long-wave frequency. Thats also the reason why those both coils have to be so extremly well adjusted.
To make it more clearly:

Those kinds of detectors may listen at the 50.000 Hz area but they could see the difference of 50.000,012 and 50.000,025 Hz at a certain frequency (the 50KHz was just an example).

btw. first it would be really important if you know on what kind of detection-principle this stuff is based before you experiment with it. I guess I gave you now the answer, so you know with what kind of supersensitive detection circuit you are dealing and now you can find a way to modify it until it's really useful for treasure-detection.


Perhaps it would be better to start with ultra-sensitive BFOs directly - making "tabula rasa" (clear table) and not messing with such "pre-ready-made" circuits which contain alots of disturbing and unneeded content.

And if you need a handholdable metal-detector better buy a Garrett Ace 250 including snipercoil an mount both on a just 30cm long pole.

As long as those "longer range detection" doesn't work reliable and on a clear level concerning on what kind of influence it really reacts, this 2in1 circuit is just hindering important improvements.

You also should input the schematics into some circuit simulating software so you may see under which kind of EM-influence the coils etc. will react on what level or intensity.


Or do we wanna have this whole riddle-guessing going on and on for years and years?


For the moment all those ToTeM-, Alonso- or PDK detectors seems to me like bad AM-Radios which will receive all kind of household-disturbances, too, because they are not shielded and designed the right way for only receiving what they should receive or detect!

But perhaps you're already on the right track and by clearing things up and improving stuff on the right area we finally get some reliable "more distance metal detection".

And without the possibility of receiving intense and highly directional buried metal signals - without radio-activity almost impossible, especially if those targets are very small - some kind of highly sensitive or for a certain area specialized detector would be an absolutly must!

Funfinder, I agree with your assessment. As a Professional Treasure Hunter/Salvor When I first started testing and encouraging development of Frequency Discrimination methods in 1980 there was adequate hobbyist metal detectors on the market that would detect coins & jewelry at shallow depths. Not much was available for the Professional Treasure Hunter,or Salvor, so we would make modifications, or try to come up with innovative solutions of our own. This is when the Frequency Discrimination from a distance to detect deep buried Treasure Trove was born and implemented.

My interests is in detecting large Treasure Troves buried deep underground or under water where conventional Metal detectors lack the depth penetration to reach the targets I am seeking. Although technologically primitive by today's standards, the first MFD's I used throughout the 1980's were fully electronic, both transmit & receive. I was fortunate to have enough inventors interested to provide me models to Field, and comparison test. My intent and purpose for Frequency Discrimination was never for detecting small ,shallow depth targets, it never has been, and is not now. So I have no pony in this race for LRL shallow depth detection except to point out the Skeptic Con game the owners of this forum are playing on it's contributors and viewers.

I applaud those who are making an effort to discover, and share with others a viable method to make a workable, shallow depth, discriminating LRL, that has universal appeal to hobby metal detectorist. It's a huge market, but will not be won without a fight from those with a vested interest in the lucrative Metal Detector industry

It is understandable that those EE's & Techs embedded in the system that earn a substantial income from the hobbyist Metal detector industry would be concerned about the increased interest and growth of a concept they don't understand in a competing industry.

With all best wishes, Dell

Or vice versa.

Hi Andreas you can use this PD without ferrite or change it by transmitter 433Mhz is better. I improve it.

Build your own MFD using these instructions -> http://www.geotech1.com/cgi-bin/page...mfd1/index.dat
Guaranteed to equal or exceed the performance of any other MFD available.

The fact is, we understand the LRL concept as well as the manufacturers who know what they're doing. The self-deceived LRL sellers ... well, we're way ahead.
In fact, we're so scared that LRLs will take over the market and make conventional metal detectors obsolete, that we operate a website dedicated to LRLs, and even freely publish designs such as the one above. :lol:

Yes, I remember very clearly when Carl started that Con, to try to put me out of business. Dell

Why ???? :angry::angry::angry::angry::angry:

Hi Nicolas
No! The bad news is ... I can not present what exactly detecting.
In the original PD the engineer knew very well exactly and they used transmitter. The old engineer (maybe Alonso) don't care, if the receiver is good helthkit, but the whole all in all
I hope if a member can build it, he can understand me well

Here is the best PCB design for clone, bottom and silscreen sides.

For Qiaozhi
This is pic a real clone english-PD.

Dear Andreas!
Thank you for sharing with us your effort!

Sneshko

Sneshko Don't thank me. My gift is only a PCB, because some members here knows all, but they cannot draw a PCB. About schematic has not secrets.. this is classic with small mods. The big problem is that too difficult to configure. In the future I accept thanked by members can make this so difficult regulating . I fervently hope.
regards

Hello Andreas

Bravo and congratulations to this beautiful project. :thumb:
I want to learn more about PDs and will try to build your PD project.
As a first project I built the TOTeM PD. Unfortunately I have a little problems with false signals in the north - south direction and contrary the same.
Your clone AlonsoPD will be my second project and hope something more to learn about PDs.
Maybe I can thereby transfer some mods in my TOTeM PD.

Thank you for sharing your knowledge with us.

Best Regards

Hi Andreas

Please check the Two Transistor it's proper?

The Correct: NPN transistors require a positive base signal to energize (forward bias).

Hi Nikolas
This is correct.
Original PD has D4,D6 diodes 1N4148. I replace with two NPN transistor work "as diode" if unconnect base
With this tip we have more temperature stability , because NPN protection inside plastic case and we have the same result.
R22 use for stability pot
C4 use tantalium. If you have not connect serial + - - + two electrolytic capacitors 22uF
U4 use only 78L05, because Lseries has more power supply out stability
Cx remove.. is not important
Led2 use a hight bright yellow LED is better for this stage
If you have not R6,R6A=680K you can replace 1M

Other tip. If you have note D2,D3=1N60 you can replace with RED LED!!!!!!!
Yes my friend, a poor Red Led (no high bright) work as diode perfect if frequency is < 3MHZ
regards

Thank you dear Andreas for this details and tips

We will try to do it if I find the time.

I await your response to my email. Thou hast promised when you return from your trip

Thank you Nicolas
I think today we finish with schematics and PCB
Here is transmitter without modification

Hi andreas thanks
But I cant understand these connection

J1 = ?
Trans = ?
JF = ?
P1 = Sens= ?

please explain good these connection because I think J1 is supply 18V is not for transmitter

J1= 2X9V Alkaline
Trans= power supply connector for transmitter
JF = connector feritte - coil
PI= 47K multiturn pontesiometer

Hi Nicolas
Is very clean
JI (on PCB) is for connection batteries (two serial 9V=18V)
Trans (on pcb) is for connection +/-9V transmitter
Later i publish all connection with a diagram
regards

Dear Andreas!
Thank you for sharing ..
Regards and all the best!:)

Mr. ANDREAS.
Can you help me?
How to do MV Alonso TX coil?
What will be the diameter of the coil, the coil wire diameter and number of laps will happen?
Thank you.

Hi all
Next step is omega-coils
attachment PDF
Note1: Original schematic publish Qiaozhi has for Tx coils 12+5+3+12. If you seePDF my omega has 12+3+5+12turns. This is correct.
We need high peaks RF transmitter with low-level modulation signal for better calibration
If we work with 12+5+3+12 turns TX coil you have 100% modulation signal 400-800HZ
with 12+3+5+12 modulation signal has level 45%
Note2:The dimensions are critical , if you want a properly nulling
regards

ANDREAS NEED HELP POR END THE PD
 

Hi Andreas here the image of my omega coil and i have much images of my prototype but I need some help to finish this project I have done many tests with many types of omegas and ferrite coils but I can not achieve to detect a coin at 50 cms as morgan says so I would like might help a little, I think I'm just a bit close to it and I could make the PD detected a magnet at a distance but I need even more distance also able to detect the two components of the phenomena electric and magnetic components.

Here is a picture of the omega coil according to the ohmic resistance pointing by Morgan, I think I'm wrong on some things but I think the whole secret is in the type of turns of the ferrite and the omega maybe i think i am near of make work the Pd alonso.

I HAVE TWO PROTOTYPES
 

HERE OTHER IMAGES

I think your problem dear wiliams are the location of your coils
Firstly you do not have the zero point between the coil they are almost in the same axis we must shift
second one must have a good calibration at the coil with ferrite. it must be adjustable and mobile

Alonso PD
 

I do not understand what you mean with that william or axis of the coils.
and you observe a position at which the ferrites are with respect to each device omegas?:???:

I think this is the correct position as established by alonso pd.

SALUDOS.

Hi, I mean with >>>>> Wiliams Tim Williams, but I did not write that wrong sorry

I do not think dear Tim becaufe the magnetic chapms are parallel
mean overlap. So to have a zero points must be moved one of them
is the omega coil low ferrite or down as I have represented on your photo

Look Pd Totem that is 100% correct
and this picture by andreas

and ferrite adjustable for calibration

PD
 

Are you sure?

let me experiment this again though I've done before and when separated much the ferrite antenna from the omega nothing magic happens, but I'll try again with omega coil did in a different way.

But I would also like the opinion of Andreas or someone else

For the confusion.... don't worry

I send you greetings and a strong hug

LRLMAN.

Yes dear I agree with you

However, Andreas already mentioned before in this topic see his talk here with Qiaohzi
since comments # 6 and later

I sent you an email before and I'm still waiting for your reply

you saw your inbox?? or you've ignored

I want to remind you again

What Nicolas is saying is that you have the ferrite in a position where it cannot be nulled. TOTeM has the ferrite placed in the null line of the TX coil, as described in ITMD Chapter 14. This null is quite easy to find, but Andreas says there is another null position which requires micro-adjustments to find. Whether this second null position has any benefits over the first, is something you would need to figure out.

Ozzy, how come you expect your atari to work since your PD tentative was a complete failure and you know that? Do you think all members here are idiots or just the ones that you want to fool into buying your book?
Your desperate commercial gimmick to your book is pathetic.
Revise you schematic and honestly tell it that thing can possibly work as LRL for gold or whatever buried metal?
Besides, ask that dude who bravely took the chances to build it, if he found anything to date besides random noises?

Gotta go. See ya on tour with your 'black sabath'.:D

Strongly agree
very sure he will understand, making experience
It is not Nicolas Tesla :lol::lol::lol:

Hung - how can you comment on a subject you know nothing about?

Anyway, even if you order one, we'll cancel your order. As we would hate you to actually learn something. :lol:

As it says in the book: "Unlike the original PD, the TOTeM project is easily replicated with a little care and attention. It easily passes all the laboratory-based tests used by LRL experimenters, and certainly appears to react in the same way as the device in the internet videos. Whether it will lead you to treasure or not is maybe another story, but at least you will have the opportunity to explore the pseudo-scientific world of long range locators for yourself, and make up your own mind on the matter."

There is nothing misleading in the chapter, or any false claims. It is what it is ... an experimental pistol detector ... and you make of it whatever you like. Just remember - here there be dragons!


Do you have to be brave to build an LRL?

I believe he enjoyed the experience and is still experimenting with the unit. Anyway, he has as much chance of finding something useful with TOTeM, as with any other electronic LRL (including Mineoro or your own Heath Robinson efforts).

Bollocks. I can’t remember anything.”

PD
 

Hi Mr. Hung, I would like to know your opinion on the exact position of the ferrrita regarding omega coil as I know you did the PD with much success, why do you not helpme a little with this project.

I also have a problem with green led, this does not turn, I do not know if the pcb is something wrong or has led the polarities reversed.

in the device of 6 pcb from alonso, I have dificults to increasing distance detection of a coin with switch in central position working ferrite-omega

but the PD of a single pcb as the Greek Forum, the problem to detect the coins to more distance is less with a distance of a 22 cms with good iron discrimination.

I have a videos i send to qiaozhi or someone else for upload.

Greetings Dr. Hung

Please relax. We have time, step by step we can see all false infos present here from......, about this PD. For example extreme detection a coin. If healthkit receiver work with stability etc etc.
I publish this thread, because i believe is time open a myth and publish here the real possibilities.

:lol: Funny post.

Actually I do have an idea to where Dr Hung would place the ferrite.

I'm not sure it would be well balanced in that position. :oh:

Very good. :thumb:

Thanks Andreas. To find the normal detection as a regular "enhanced " detector, on the edge of stability, will be interesting too.

:lol::lol:

PD INTERESTING
 

I like that Andreas

I really liked what you said is important to know all the details of this machine to see if in fact if it works or not, I need to finish this project.

I also want to tell you that I have been testing with the PD that which have a single pcb and I detected very erratic way an object buried beneath a planter at a distance of 10 mts, about it i checked the place with a normal metals detector on the spot where the buried object is that the object appears to be large.

LRLMAN.

BEGINING
 

Ok Andreas and friends,

Where do we start? for the list of the components of each pcb? or the preparation and calibration of the ferrite, or for the preparation and calibration of omega antenna?

Want to do it here....... or in RS?

Please comment.

LRLMAN

I can present here place feritte with dimensions between omega place.
Anyone can confirm the maximum signal receiving feritte-coil in this place .
I will try to make videos to show that the signal actually becomes zero.
You can see that the position is not :nono: "TOTeM has the ferrite placed in the null line of the TX ...", as reported by Qiaozhi.
If we put feritte in the null line of TX, we have not stimulate omega coil via feritte. In this case we have not on condition regulate all together.
As you know i am not RSforum member, because old time i have many attack from "guru's members knows all :lol:" and they don't publish more infos, because they believe, with own informations i can build a commercial project.
This is a joke for me, then i delete me from RS
The true is, this members never build it, because, if they build it members start a commercial project.
In this case the best choice for me is publish here all infos about PD and your RS forum you can have help, by guru's for more infos about nulling and calibration feritte together with omega coils.
If you have not help in RS forum ( i am sure for it), i can start again.
regards

Friend lrl man.you found object connected omega coil and ferrite or only omega coil?

This sounds good to me andreas we need to start with this and see what happens.

I've seen the videos that you have exposed in your youtube channel about your PD and you can detect some objects and all this is very interesting, I see a video clearly showing the detection of a small magnet and I like a little since my PD also detect a magnet but just to low distance.

Greetings.

Posision of ferrite regarding omega coil
 

Hello Fred,

Where you think that Dr. Hung would place the ferrite regarding omega coil???? which type of ferrite? because I believe that he was used a different ferrite that was used by Alonso in hes proyect, because the ferrite Alonso used was two flat ferrites and the used by Hung was rounds.

LRLMAN.

I found some spots and one of them is a metal, i don't know what kind of metal it is, but also was detected by a normal metal detector, this is a big object because was detected by a garrett metal detector with a multipliers for depth Garrett Grand Master Hunter CX II

As I said, I can not know what kind of metal is because it is located below a large round planter and I can not destroy it.

And the PD, must be connected the ferrite-omega together.

The only position of omega working how a metal detector.

LRLMAN.

No!!! helthkit receiver is important. Later i replace receiver-helthkit with a very-stability new receiver, because, the original helthkit receiver is unstable:frown:.

Dimensions between feritte - omega coil.
As you can see feritte is not in the null line of the TX. With experiment you can see feritte-coil has without nulling output signal 150-200mVpp minimum
Regards

Are you saying there is another null point at that location, or is the ferrite being nulled by a separate coil?

I work with your schematic. Attachment pic.
For specific feritte, I use turns in the Plan. I believe they need depending on the magnetic permeability of each feritte we must be experiment with turns. For my clone i use a chinese feritte from AMradio orthogonal 100mm. Yes with microcalibration horizontal axis actually finds a "dead hole" with zero signal. About y axis, i think we need small luck:rolleyes:
Now if we find the dead point and put a 4n7 capacitor pararell with L7 we can see omega coil need caps= 1n+6n8 and receiver coil need 1n+1n8 for best resonate all together in xxxKHZ
Upon verification of capacitors that have the same values as the original plan, we are confident that we have created a clone, working with exactly the same values ​​parts.
I repeat again, the big problem is find this "dead point". I believe Alonso knows exactly the frequency and made arrangements in the Act. I have this opinion, because the location has put feritte (real PD) is ....with hot glue.In this case, maybe he knows near zero-point area and he find the best with practice
regards

Good response Andreas this is the trust and real.
You are the best

A note
 

Sorry for my false.
I see again schematic publish here #30. I write R50=39K:frown:, please replace R50=390k. Original schematic use R50=470K. I find is better work all together with 390K value
regards

Well, i think Hung has no clue whatsoever to where to put any ferrite, same as for any technical matter, so my idea about it is non-technical as well and is (perhaps) a secret place.
So to keep it technical, I can say he would probably put it on top of a calculator, or attached to a piece of string and "feel" it pointing to the golden ring or statues he planted nearby.
Nothing useful as you can see...

Hi, Andreas,
what do you think about the final principle of it ?
The way you explain it, it look like you are building a very compact kind of two-boxes detector, finding an extremely tiny null, very close to the Tx loop.
Do you think it could be? And that a detector in such a configuration has something special?

Only to tire people's hands. for both boxes nothing special. and only for gold. ansi we do not know what prices are
I think this is unitul unless it is at least a long range. So it becomes a bit special as traditional.
I'm with you Fred about this quetion

Hi Fred
Yes this unit has something special. With this special null, unit detect very easy magnetic piece. My first experiments, unit detect very easy aluminium piece 6 meters distance, 30cm depth (i don't know how old is this alu-piece) and the strange for me.. if detect magnetic-piece unit stop detect magnetic lines from earth.
Joke is ... with perfect calibration all together coils-housing detect one euro ONLY 12CM DISTANCE.
I remember some members say here.. unit can detect a coin 20,30,40..cm distance. Maybe detect capacitor-phenomenon via hands and believes detect coin, because if don't make fine calibration produce this capacitor phenomenon.
For me this unit has many interest points and work same method other unit "name englishPDfor gold"
I try find free time and fine weather for external tests
regards

Hi Andreas,

Between PD and the Crypton, which is better in terms of range of detection?

Regards...

Hi aulook
we have two units with different philosophy. I cannot find something same, only alarm circuit is same
My opinion. Many -many engineers try build alonsoPD withouts results. Only a greek engineer build a PD (name magicPD), but he use only receiver helthkit with a big ferrite (without feritte-coils) and maybe have small results.
Few months ago, i build an other myth (name englishPD) with perfect results. In this case i use a special feritte, because englishPD the secret is the special feritte.
Now i can see AlonsoPD and english PD has same philoshophy (method detection).
If i understand well ..what happen inside , for me is possible 30% build a PD only for gold.
I have a personall theory, but sometimes i have not answers for my questions.. who knows!
I know only one now, this extreme units need special CAD labs for produce same results. In this case i understand well now, why amateurs cannot build, but only with luck sometimes build a real unit.
regards

Thanks Andreas.
As I said before, and by your observations, it also looks like the PD could work on the fluxgate magnetometer principle...
Some said that the magnetometer effect should be nulled out to "work" properly.
However, the main question remains: What is "working" ...

Hello Andreas
I like your project and would like to add something.
I'm no electronics expert, but with CAD its not a probem and can help you.
If it is helpful, I can construct you a 3D model with exact data of the Clone AlonsoPD with all what you need and place at to disposal here in the forum.
So it could be everyone watch, or measure it himself.

What do you think, that would be a helpful?

Hi Goldmaxx
I like your project and would like to add something.
This is not my project , i build only a real clone
I'm no electronics expert, but with CAD its not a probem and can help you.
Thank you very much about your help. I have not problem with CAD, because it's my job, the problem (not for me), but others members is.. they have not machines work via CAD for build materials
If it is helpful, I can construct you a 3D model with exact data of the Clone AlonsoPD with all what you need and place at to disposal here in the forum.
So it could be everyone watch, or measure it himself.
In this case i think you need a cdr file (corel) by me and with this file you can make a 3D model for. I think this 3D model can be helpful more members
regards

Hi Andreas

Thank you for the quick response.
I can construct 3D CAD model and create a 3D pdf file from this model.
A 3D pdf can anyone who has the adobe reader (latest version) installed open and watch it.
You can rotate the model, zoom, represent parts in show or noshow and the most important, measure the parts and distances.
I think it is helpful for anyone here in the forum.

Yes, to create a 3D model, I need cdr files or drawings with dimensions from you.
If it is helpful, and it's okay for you, I will send you my email, so can you send me the data.

At that time, I've made for the Totem casing one.
I post it here again, and you can test it.

If you open it, first click with the left mouse button on the image to activate it and then you can rotate it with the left mouse button and zoom with the right, or scroll wheel.
At the top of the screen is the toolbar, you'll find all the tools to measure, make cuts and everything else.

Have fun with it.

PD
 

Andreas, how many centimeters has a 1 euro coin?

one of the two units that I have built, only detected a silver coin of 3.5 cm diameter to 15 or 18 cm away from the coil in the single mode omega.

This unit is it only has a PCB because the 6 PCB alonso unit can't detects more distance for the coin.

This is the type of the coin, that I say is the biggest on image in the left side

This is the image:

My PD
 

Andreas, Another thing, the omega coil that I did, have the followings sizes :


TX: 8.5 cm diameter with his small center of the omega have 4 cm diameter
magnet wire of 0.30 mm (0.29 mm here in mexico) with series 9+6+5+9 turns.

RX: 4 cm diameter, with magnet wire 0.20mm with 26+26 turns.


The turns that I put to the TX and RX antennas, was because morgan gave the values ​​measured in ohms and only with those amounts of turns and the measures of wire magnet i could get that values, I could never get those ohmic values ​​with the type of magnet wire and amounts of turns that morgan said.

Interesting post, Fred (fluxgate mag)
 

Back in the 1980's I build a bipolar pulse induction metal detector that worked fine with an air core searchcoil. I replaced it with a ferrite rod "probe" type searchcoil and was surprised to discover that it had become very sensitive to earth field-- I'd inadvertently constructed a fluxgate magnetometer.

--Dave J.

If we have perfect regulation all together max detection one euro coin is 10-12cm distance

The turns coils on feritte depends on the magnetic permeability of feritte.
Need for experiments or more luck
About omega coil , this is a helthkit, my opinion need replace with a better stability schematic. I don't like it

Hi Dave J.
Maybe you are correct, but is not exactly this. As i say few posts ago, i have a personall theory, but i have not answers for all my questions
Regards

PD
 

Andreas, i have some doubts and confusions, I have a question about this drawing that you present here are the measurements of the small coil that goes inside the omega TX; in this picture I see a TX and if I'm seeing good, it appears that within the circle is the RX coil to 35 mm?

So where is the small circle of omega TX coil and what measures should have this regarding the large coil TX?

also should measure 35 mm in diameter?

because if so then from where the 27.56 mm distance?

The circuit block diagram of a bipolar PI is just about the same as that of the typical fluxgate.

Ok Andreas then you are saying here that the type of omega inside morgan present of the head PD Alonso should be replaced by another type of TX and RX coils? may be for 2 doble OO?

Like as showed Esteban in an ancient thread or such as you did in your prototype that worked better?

like next images:

Or change the schematic and components???

Andreas,

I also have doubts about the position of the ferrites with respect to the direction where this points in cloned prototypes, if you look.... all ferrites are always pointing to the wires that going in the direction to the TX and RX omega coil,

electronically has something to do this for a good detection of this device?

see next image:

Attachment pdf file.
Red lines is turns wires. Up for omega coil and down for receiver coil
Black lines is forms-driver for coils
regrads

If I good understand Andreas mean this

the RX is in center of TX? If not correct me

sizes of OMEGA
 

Hi Andreas Sorry for so many questions about, but the questions are many to finish this PD properly and to see if it work or not,.. if not then stop this project.

although the idea is to start make a different omega which that I have
to advance in this PD.

I have some more questions about the omega image:

I think all these questions are very important for making a perfect omega with some accuracy in order to give the PD a high performance.

Today (nw i am out my base), i export a PDFfile scale 1:1 via CAD. You need only print this and you have real dimensions for omega coil and Rx coil
regards

Hey Andreas that sounds much better,

Yesterday I connected to PD an Omega coil equal that which morgan exposed in RS for his device but not detected little more distance than the omega I did, only 12 or 15 cms distance for coin similar diameter to 1 Euro

OMEGA MORGAN: TX: 5-2-2-5 and RX: 14+14 or 30+30 all magnet wire was to 0.15mm

handling this wire is very difficult, this is very thin

Attachment PDF files. Print this and you have real dimensions about coils
About magnet wire don't need is a myth. Simple coil-wire is enough.
On information in the RS forum you believe there is truth;
I don't think. I'm sure Morgan and his friends, he gave affairs and opinions, just because .... don't know or they don't build this PD by members (Especially for my person, fear units production:lol:). I think they knows only the operating frequency of the original PD and I say this, because, using the same frequency in PDK

The Generator
 

Andreas, A signal generator can be used with the PD locate a treasure. or Pulse Induction Detector may make stronger the phenomenon that can be detected for PD..

I don't know if alonsoPD need a external signal generator or PI for stimulate a target.
I think don't need.
regards

I did this circuit just to see how it behaves pd with a sign around 68 khz

Hi Friends, Hello Andreas,

I tell you that i did the coil exposed by Andreas but without good results
this detects much less distance than the omega coil I made ​​earlier,

I've been looking a lot of information about how to make an omega coil and reviewing many images and found in my papers a document to Andy Flind where is the way to make a bobin omega compensated for a metal detector and catches my attention because this omega Andy has other features elaborate and I think this could help us develop even on a smaller scale an omega coil but need help from someone here on the forum who can do calculus to make it equal to that of andy but in a smaller size perhaps about 8 or 9 cms. diameter

this is important because the omega coil exposed by Andy I think this well balanced in its measures as should be a real coil omega because maybe this can work well in the Alonso PD.

LRLMAN.

As you can see #89 ......with perfect calibration all together coils-housing detect one euro ONLY 12CM DISTANCE..
Alonso PD don't work as a real MD detector, but as LRL
If you replace C4 (see #116) with value <10nF, you have more distance detection.
Ofcourse with C4=100pF... 470pF you have best distance detection.
I made this clone with the true values ​​of the components posted here few years ago.
I saw this is real "distance detection" of omega-coils when everything configured correctly. In this case we have a real LRL and a "poor" MD.
You can ask the morgan. He has the original PD, he know well the real distance detection and measurement real frequency tune. If he publish real infos (Rs forum), i don't know, because, i am not member
My opinion... he never publish real infos or he cannot build a real clone (i am sure for this)
If we want a better MD section, ofcourse we can replace with other schematics.
I think later i replace this section
Regards

hello guys, put the tx in lrl detection, help for a little most distance range, and most directional precision, too for most centre habilities, but any persons say, the tx near of the metals point, due hig tension oscillations can null the field of electrons around the objetive buried, how a short circuit, then you see all signal dissapared, morgan say the tx help for can be detected in minor size objects

Hi Detectoman, how are you man, tienes toda la razon hacerca de lo que dices y que milagro que te veo aqui, que hay de nuevo hombre ya terminaste tu PD? he visto algunos videos tuyos en you tube de un equipo que hiciste se ve muy curioso pero bien, un saludo

greetingS.

hello lrlman, regards today i have a medium" range in right function, and other one in succes vies and 4 others in process, sayme what you from, may be we interchange opinions

ups lrlman: where you from * :)

Detectoman Excuse me, I from here Mexico, Lazaro Cardenas, Michoacan.

and you?

Ok Andreas,

Well then where we start again?

I need you to know some things about my experiences with the developing of my PD'S before starting with all this.

1 - I have two PD, one with six PCB’s and the other with a single PCB as presented in the Greek forum ok?

2 - The single PCB PD is more stable than the six PCB’s.

3 – In the PD single PCB I put two flat ferrites Alonso identical to his PD pistol.

4- In the PD six PCB’s, I put two round ferrites of 6 cms. long each one by 1 cms thick.

5 - The schematic I used for the two PD’s was exactly the same in RS by Qiaozhi version 1.20 because it had corrected the polarity of the capacitor # 33 uF 10.

6 - the omega coil and ferrite were made with almost the same omhics resistance just with different calibers magnet wires (for coil omega only) because the coil ferrite I put the same type of wire 0.30 mm but with a different turns quantity to that exposed in RS ;


It is important to say that the way that I did for winding ferrite was different from that presented in RS because with the turns exposed in RS never detect a small magnet or just to 1cm away from the ferrite, but with the new way of laps that I put on a ferrite, this detected the small magnet to 20 Cms. away from the ferrite, and only when the PD is working together Omega-Ferrite; I've also noticed that the magnet is detected by the omega, in only omega mode, but only in a shorter distance away maybe about 7 cms.


7- When I adjust the two PD's and pointed toward the ground, the pistol beeps in direction to the soil detect the capacitance of the soil and I don’t know if this is normal or how can I fix this, I've been seeing information exposed by Esteban about it but i don’t understand what he says of how to correct this detail; Esteban says: “We can find a good compromise between the both (sky and soil)” and he say that
I have to change wire the ends of the RX: “Invert extremes of receiver coil and put your hand in both sides of rec. coil, time by time. You note in one extreme capacitive effect (a kind of null) when you put your hand. If the capacitive effect is produced in down part (this is, a kind of null), invert the connections of the extremes of the rec. Coil. Is better the increasing of audio in the down part when you put your hand, this is, the part of rec. Coil near the soil”.

This efect is normal or not? Is good or bad?????

8- I notice that in the two PD's green LEDs do not light at any time and in any way and I think that something is wrong may be reversed polarity of these, could you help me a little on this? maybe with some schematic correct, and as I was saying I have no knowledge of electronics I understand very little I'm no EE here in México I'm just business manager or public accountant but I am very interested in completing these projects, not for sale of devices but for personal use because I know many places here, which might have some interesting things to discover.

I have seen with my own eyes what they can do the Alonso lrl’s when he was here a few years ago
I am sure that these well calibrated equipment can do good things


9- The PD one PCB have a potentiometer multiturn 50 k.

10- The PD Six PCB’s have a potentiometer one turn 50 k.


All this is to begin to get an idea of ​​what I did, I would like you to show the full Schematic in one piece or as exposed by Qiaozhi since I have some confusion regarding the schematic that you exposed in the area of the coil connections to omega, because the RX of Qiaozhi Schematic of 1.20 has three wires and i see only two in your schem., and TX coil has 5 wires which I can’t see on your schematic, i only see 3 connections.
Anyway I will try to analyze it with the schematic of Qiaozhi.


Regards.

LRLMAN.

lrman and all, the sky-ground effect was for me a big problem when i building the pd whit rx & omega, the original pd circuit are very versatile, whit other coil recipes, then also you have a great diversity of present phenomens whit each distinct maners of make your circuits or power measures, lrman i am in chihuahua mexico but today no have very much time for my lrls or experiments due my busy particular works, the sky effect can dissapared changing whit other coils recipes, also the sky effect automatic dissapared when the pd go at stabilzed function, then came devenue sensitive stabilized lrange detection, the pd have very much secret of operations semms easy but isnt sometimes

Last year i have a mail by seden if is possible drawing a PD only for gold.
This is a point very interest for me and ofcourse i try find solution for this.
For experiments i use my real clone alonsoPD with full modifications (for example change MD section with other circuit stability), build a new sensor via lathe and laser cutter.
After two months study and build many-many prototypes sensors, i think find solution. The big problem again is calibration all together. In this case i use other way for find delicate for all work together.
Joke !!! i know very well what i need for calibration and all steps for fine tune, but in practice after three days without results, i find solution (very difficult)

Please look video https://www.youtube.com/watch?v=1alv...ature=youtu.be
This is not dream, but real. No ground or sky effects. No detections earth lines
The unit is very-very stability and silence for other metals.
Interest is PD work without motion or very-very slow motion
enjoy

Great work my friend. I wish you good luck and too much improvement in your project. If we can detect from distance 5m we can detect also from 50 m and maybe 5 km or over:D.

Congratulations Andreas for your project, the new modification is in the RX or TX, I'm working with a LED transmitter but has not given me good results, such as a magnet detects 30cm.

Thank you for your wishes.
Modifications has all circuits. In practice don't need calibration by electronics via potentiometers alarm windows etc, but calibration via tune every new searching place. I need a final big test 15 august (of course with video), before i am sure for stability this unit.
Of course need more experiments for find minimum buried time a sample for detection.
I know PD can detect three very small gold-ring and a gold coin two months old buried, but is not enough
Notes here.
I understand now , why some members (top engineers for me) cannot build one. Here we have a mix electronic and cad with critical setting all together.
Please look again video. My prototype has many external mechanics regulators for find best points in practice
I understand now why never build a real clone by members. Sometime i believe the original PD has not a perfect calibration, because with hands and a electronic lab cannot make this.
Αbout detecting magnet. This is not really criterion, because a perfect calibration PD has low SENSITIVITY for all external sources
The second half august. I send prototypes for full testing other countries.
If they have success, this is a first real world long range detector only for gold.
best regards

Hi Andreas

Very good work, I followed another path for my LRL and I do not have many opportunities to tune only the gold, I have already changed the internal oscillator frequency from 3 to 10Mhz without appreciable changes. But I have a question, are you sure that the revelation of gold is only a general decrease in sensitivity as the gold emits a signal of greater intensity than other metals?

Best Regards

Hi Franco
Thank you very much
Negative! gold don't emits a greater signal. I am sure now, this signal is lowest, But if i understand well, we have here a "tuning fork" in a very small range band frequency.
In practice, my PD have not low sensitivity, but reject all no interesting bands via a strange filter design by me.
I know well all members try find a formula with experiments to false or not false.
But here need more. The time is near after ten days i can know more.
best regards

Hi Andreas

If I understand correctly your filter passes only the "phenomenon" generated by gold. Do you think your filter also works with other types of lrl? For example my LRL? I have tried different filters on my LRL placed between the antenna and the input of lrl, I tried different types of diodes, silicon, germanium (even the old style contact tip called a cat's whisker) and also the Schottky type, I also tried various capacity capacitors in series with the antenna but I had no results. Surely you have made a breakthrough in the understanding of the phenomenon.


Best Regards

If I understand correctly your filter passes only the "phenomenon" generated by gold.

Correct, but i need more time , before i am sure. In this case i have program send prototypes other countries for more experiments

Do you think your filter also works with other types of lrl?

I don't know. Logical don't work. LRL with passive receiver cannot use this method, but later i try.. maybe i find solution if is possible

For example my LRL? I have tried different filters on my LRL placed between the antenna and the input of lrl, I tried different types of diodes, silicon, germanium (even the old style contact tip called a cat's whisker) and also the Schottky type, I also tried various capacity capacitors in series with the antenna but I had no results.

Correct . As i write last posts, we have a mix electronics and mechanics design. Critical is micro setting dimensions. For example +/- 0,01mm.

Surely you have made a breakthrough in the understanding of the phenomenon.

Interesting for me is... phenomenon work with full discrimination. Sometimes i think ... this is a dream. Sometimes i think .. my eyes "see" false results. In this case i play again video and i try find my false. I have "lost my sleep" before i make a final test date 15 august for sure.
best regards

Hi Andreas

Should know something more about the "phenomenon" in order to distinguish gold from other metals. I also spent a lot of time to try to learn more. Since the phenomenon is revealed by Lrls that work with different principles you may think that it is acting on "broadband", that his energy has magnetic properties, electrical and optical properties, or perhaps more. Which known energy has these features? You talk about micro setting dimensions and this suggests to microwaves and infrared, and also to radioactive isotopes. On the other hand the low frequencies of operation of Lrls suggest also to a low-frequency component of the phenomenon. The isotopes gun of Dr. Bickel was based on the principle that the metals buried many years emitt isotopes that can be detected at a distance. Maybe he was talking about isotopes because he did not know or did not want to reveal the nature of the phenomenon. His instrument was very similar to a magnetometer and could be used by an aircraft in flight, so it was very sensitive. Moreover, each metal has an emission of isotopes that is different from the other metals, it is a sort of signature that allows to discriminate eg gold from other metals. If this is true it is no doubt that even a LRL can do the same thing.


Best Regards

My friend Andreas.
I believe that what you have done was building a mechanical filter nulling adjustment to position the ferrite in a similar way the front loop RX coil is required, to avoid ferrous metals in relation to the omega TX coil. Tough this might work at some extent and reject ferrous and some non ferrous metals, if you do not employ an added bias filtering specific for gold, it will be very hard for you to eliminate silver, copper or bronze. This mechanical adjustment of ferrite is a primitive way of selecting only gold, when a much better and hassle free procedure is to electronically 'trap' its 'magnetic signature', if you know what I mean.
Also, since a LRL is to be taken in the field under hard conditions and subject to bumps, a mechanical adjustment of key components might well get ruined very easily.

My schedule is still too tight but I hope soon I will be able to show here the couple of devices I have been developing including the MX8, with a kind of technology I still have not seen in any LRL so far.
Cheers.

Do you know what you mean?

Hi Franco,
according to some old posts, here in this forum, the "isotopes gun of Dr. Bickel" , was a very sensitive gamma spectrometer, which is a well known instrument.

Hi Hung
Nice to see you
it will be very hard for you to eliminate silver, copper or bronze.
Please look again video. I have not signals from silver,copper or bronze. You must be sure, before buried gold rings and gold coins i buried some foils from silver and many scraps from copper and bronze. I make a real test place with all parasitics and scraps and of course very near 220V ac camples
... is a primitive way of selecting only gold,
Of course you are correct. The best way is hot-glue as we can see inside orginal PD by Alonso. In this case use lathe , lazer, cad ,pcb program are primitive
when a much better and hassle free procedure is to electronically 'trap' its 'magnetic signature', if you know what I mean.
Few years ago try esteban with this. I think there is a better way
Also, since a LRL is to be taken in the field under hard conditions and subject to bumps, a mechanical adjustment of key components might well get ruined very easily.
About this you must be sure i solved 100%
best regards

Hi Franco
You are confused (please this is not attack your person, but a opinion, because you try strong about LRL detection). It's simple, but i cannot publish more. Please open mind remove all about electronics and maybe you find solution.
Please read wikirota, there are interesting threards about buried metal.
Only one you are correct 100% the solution is microwave or IR fasma

Hi Andreas

It's very interesting the work of Louis Rota, thankyou.

It's my pleasure.

The second video, for those who study the phenomenon and they trying to build a detector for gold.
https://www.youtube.com/watch?v=5RpZ...u.βε
Interestingly, PD if calibration precisely for the detection of gold, cannot detected a magnet more than 10 cm distance and are not affected by any transmission frequency
Best regards

Hi Andreas
It 's very interesting especially the revelation of the gold bracelet to more than 1m or 2m. This means that the "phenomenon" is also active for gold that is not underground. Also in this case the sensitivity is greater in the direction south north?

Best Regards

very good dear andreas
Congratulations:)

Does it find gold in metal box?

Best direction is north-south.

Thank you. Need more time and extra modification before is ready

I believe cannot find gold in a metal box, but if.... the box is destroyed from humidity etc maybe is possible, because gold has a contact with ground. We will know in the future by the users if this is likely
regards

dear andreas
I wish you success .:)

Dear Andrea hι
Do you think deserves to construct the PD;
Is it difficult to work it?
ευχαριστώ

Do you think deserves to construct the PD;
Yes deserves, but it's very difficult. Original by Alonso is the base, but calibrate together all is difference.
I explain more. My first results and experiments i "see", few years ago, before build the first real clone and publish here. If you remember i publish here ,my first posts this thread "....i am sure this is clone and later i start experiments outside lab..." but my firsts experiments outside all setting positions don't work and PD need again calibration, the other place need again calibration and again and ....etc etc. In practice we have a unit with other setup for all places and don't erase magnetic lines by earth. Now this problem solved.
My opinion original PD is best of best LRL for all old buried metals without discrimination, but all steps for perfect calibration need long time and ofcourse you know well what do you want about calibration. Maybe this is the true "why never this PD start mass production" by first designer if is Alonso.
Modifications for Gold is other. Need filters, ferrite with special specification etc etc
Now about some amateurs for example our country they say "i build it and work and i find gold etc etc...." i believe fantasy is perfect for ....mind
Is it difficult to work it?
It's easy with standard steps-calibration on place by user
Να εισαι καλα

Thank you very much for your answer and your time.
We believe that the FG80 or FG90 not work in relation to the PD?
A talking about the same manufacturer.
thanks.

If you want my opinion, i believe this is not Alonso PD. I have sense about who is designer, but i don't right publish here.
My sense is strong. In this case i am "free" use some parts without license.
But if i am false about my opinion, we have only one "brake" for mass production. This is the long time for calibration. For example i want (PD without discrimination) minimum 10 days for calibration. This long time need for calibration all together and choice between many-many ferrite (same parts-number) the best for use. In this case need small luck for find the best parts for one PD.
Regards

HI
 

Does this product is in the market. And how much the price?

Dear Andrea Thank you for your answer.
some questions
calibration of ferrites do by moving up and down the ferrite
through the screw?
The commuters ferrite front back?
Led1 is the low battery indicator?

If you replace C4 (see #116) with value <10nF, you have more distance detection.
Ofcourse with C4=100pF... 470pF you have best distance detection.
that the tantalum capacitor're replaced c4 10uf
thanks in advance

a question
who knows how to answer me.
The ferrite coil creates oscillation in the passive receiver input?

Now i am interested only in stability and modifications
regards

I think are very clean. The first one i use a copy from original Alonso. Without mods i see the first results. Try with this or... better use opinions from Greek electronic engineers. We have best team our country and forums with realistic opinions
best regards

Hi Andreas,

thanks very much for the effort and great information here. I want to build this Alonso-PD clone and spent many hours in this forum to collect all that spread info. Its really a pity because some information is confusing and messed up and also sometimes contains erros. Therefore many beginners don't know how to build the device and get frustrated. I want to try to fix it but I need a little bit of your help. I want to put the whole project into 1 Zip file for everyone to understand and build the device.

hi all
hi andreas thank you for this project
please post picture of coil's
best regard

Yes I've built the circuit and it makes sounds like a geiger counter. It does not react to any metal or magnets. But Im not sure how to connect the coils, main pcb and transmitter pcb correctly. There is no diagramm/schematic with everything connected together therefore Im confused.

Can you please connect the lines in my post 184 with the picture "How to connect everything correctly?".

http://www.longrangelocators.com/for...&postcount=184

Thanks very much

Nice work but you need much times to calibrate and make it work

look here here in this comment

http://www.longrangelocators.com/for...&postcount=116
and

http://www.longrangelocators.com/for...&postcount=120

see pic

Calibration is not the problem. I don't know how to connect the parts correctly. Im also really confused I've found error on Transmitter PCB versus schematic.
Capacitor C4 is placed wrong on PCB and R7 is not existent. We really need a diagramm with all parts connected together to locate any possible errors.

I will try to complete the connections in the picture from post 184 but I need help because Im not sure if thats correct.

Here is the error I found on transmitter board PCB:

The pcb true image


http://cdn.top4top.net/i_a838d1e1c30.png

Okay here I've made a connecting diagram of this project. Its not complete because I don't know how to connect the RX coil and Ferrite (Please help).

Please check for errors and let me know how to connect the missing parts.

Thanks

Thanks brs,

your're right it's much easier that way.

UPDATE UPDATE UPDATE !!!!
Finally I've found out how to connect everything together. I will try to update my post with new diagram or post a new one in 1 hour.

Final wiring diagram
 

After digging through all the posts and threads on this forum I've found the answers.

This is my final wiring diagram Rev. 1.1 2014.
If someone finds any errors please let me know and I will update it.

Daniel

I had good results with alonso 5 pcbs combination with coil heatkit gd 348..estou working on it

I made this lrl last year with the same configuration above but does not give a promising result. True, this lrl is very sensitive to the phenomenon but is not stable, it drifts from time to time. So the operator should re adjust the sensitivity oftentimes.

Regards...

This is the fault where we have so much amplification in DC. As with the metal detectors you need a button for retune or a motion amplifier.

Regards

you have an idea for improving the pd and better performance?

Sorry but I don't know well this lrl.
Best Regards

thanks Franko

PDK Housing
 

Here is my PDK housing for the Alonso Clone. I needed some good housing to do the calibration exactly. I've designed my own housing in AutoCad Light and used my DIY CNC Router to create the parts. Now I have to search for an approriate Ferriterod.

Very nice work.
You might have problems with coordination.

Thanks. What do you mean by coordination? Each coil can be moved by small increments for adjusting.

Very nice design, daniel. You can teach Alonso in many ways.

Probably ferrite coil should be more center pointed in regard to omega coil.

There is the case ferrite having to move either left or right of the center of the coil . Not sure that 's the best placement in the center .
You tried to do something that can be moved left or right to do what your settings correctly.

is that have someone finish successfully this project

No, the ferrite cannot be moved left or right in this design. But if it is absolutely necessary I can modify the design of the ferrite holder and cnc new parts in a couple of minutes. I used the measurements from Andreas's post 81:

http://www.longrangelocators.com/for...1&d=1391447412
http://www.longrangelocators.com/for...1&postcount=81

I've made ​​the pd,
and therefore I tell you some things.
It will help a lot in this coordination.
And as far as possible fixed structures,
because easily detuned.
I will recommend you for the reason that you have the technology in your hands, and you can do a good job,
I will recommend to the ferrite to create a micro coordination.
so that you can restore the coordination Assists per moment where it should.

Thanks very much! I wll then implement a X/Y adjustment in the ferrite holder. But first I have to get a ferrite from old radio somewhere.

This is not difficult.
You can buy a ferrite.
There is no need to look old radios.
I hope to have good results.

Omega Coil finished
 

Omega Coil finished :)

Nice. :thumb:

Did you design the CNC router yourself, or is it from a kit?

Thanks! Actually it's a kit I've bought many years ago. I did also design my own CNC router but that complete kit with controller was much cheaper. Nowadays you get full CNC router incl. software for smaller price because competition is very high.

Hi Daniel.

Congratulation for your fantastic design:thumb:.
You must know that at original Alonso's PD, Omega coil looks at top of housing (you must turn it 180 degrees).

ET on The Earth
http://www.youtube.com/watch?v=N30KlJI5f4k

The ferrite coils from Alonso PD could be exactly in one of these atomic clocks. They are already tuned for 60 kHz.

Hi all
Sorry for delay send about more infos for PD. After experiments, three months ago, i see PD need new circuits design. I make new design with new extra circuits for more stability , filters etc. Attachment inside PD a photo. I hope next week i have final experiments of course video etc.
About reject magnetics or soil lines, ground effects, full rejection all metals except Gold, rain, AC camples 220v, temperature etc, has been solved.
About searching without motion or very slow motion PD work has been solved.
best regards

hi all
thank you very much Professor Andreas for sharing your projects, I realized your pd but I encountered some problems
1- my setup works as a Pulse induction because it detects all metal 50 mm
2- both led blinking but no sound only if I connect the Q4 collector to the resistance R40,maybe the 555 timer is blown I do not know
please help me
thank you in advance

Hi ouiarabe
PCB and schematic have not error. I am sure 100%, before publish here and of course first prototype work with this. I think you have put "bad part" or put "invert" 555
My opinion.
Check botom side pcb with your eyes, step by step for problems
Check soldering if are correct
and final replace 555 and Q4 with new
The best choice is .. use osciloscope and check all sections if you have a friend electronic engineer
best regards

accept my respectful greetings ANDREAS teacher and thank you I'll check and change the IC 555 and T4 and attach images and video of the printed circuit

hello!! congratulation andrea.

hi professor ANDREAS
I checked all the welds and change the NE555 and Q4 but its same problem I will attach a video
thank you for your help and I await your recommendations with pacience
thank you in advance.

Thank you stergie

Via a video i cannot find solution, but maybe...
Unconnect C15 and connect power supply. If you have the same tic-tic on buzzer, replace buzzer with other attchment pic.
best regards

It's my pleasure can help you. About PD. Real Alonso clone can detect materials and detect a small magnet from >50 cm distance.PD for gold cannot detect materials or magnet
best regards

once again thank you very much for your help
this is the result but do not make fun of my modest presentation

https://www.youtube.com/watch?v=H-Ze...ature=youtu.be

Is it ok to use plastic casing for this PD? or it is necessary to use a plywood or ply-board...

I have 3d Printer. It's better and easy via this machine build everything via plactic ABS, but here i see the best choice is wood. Calibration is extreme.
I think plastic produce electrostatic phenomena. We don't need parasitic signals
best regards

Thanks a lot master Andreas,..

Hi
First for all
I am not master-teacher-proffessor etc. Simple Andreas is enough
About discrimination is simple. Remove receiver coil and invert back-front. Now if start again fine null you can see you have discrimination. That's all
best regards

It's a big honor for us.,,to get a fast response from you sir (Mr. Andreas) and I'm bit follower of your project like PD,and I would like to build some of those. But I don't know which one of your best PD..,.can you give me and some other here a circuit with PCB layout?

PD pistol is not my design. First present here from morgan few years ago.
Qiaozhi finish full schematic after opinions and studies from many-many members.
I must send a thank for members j-player, esteban, Qiaozhi, Aft etc present info without secrets. This PD has a magic for me, because, few members try build it complete without results.
Morgan is the first member, build working only ferrite stage.
Men in my country Greece build the MD section without fine results.
Of course many members build complete this in their fantasy.
It was a personal challenge to finish it complete. Only one member with substantially help me and I will again send a big "thank you".
This is generally the story.
After first really experiments and full modifications a suprise for me is.. PD detect only Gold. This is a big chapter, but i cannot publish more.
The lesson is one. If you try, you can build your dreams. It's easy if you can study with open mind. Please don't forget with OPEN MIND
best regards

Ok sir thank you,..for a lot of information..,

Hi ANDREAS
Is it possible to explain more
Remove the receiver coil and reverse-back front.

attachment pdf file

Thank you Andreas

Is your choice if use DD or concentric coils. I use omegac coil ONLY, because, i build a clone
best regards

hello Antrea pls help how is the correct ??

Nice work. :thumb:

[QUOTE=stergeol;150636]hi
congratulations it's a beautiful work I hope it gives good results
please what is the correct position of the ferrite and coil Omega 1 or 2

hi any body can put here all correct file in zip file .

Hi Stergie, use No2. 150 turns is front place on feritte.

many thanks andrea....

Hi all
PD only for Gold it's ready. Need only final test this month, of course with videos.
I use only one stage from original PD Alonso nothing more.
Very small size and weight, full stability without humidity problems or sky-grounds effect.

Now need only fine weather and small free time.
Note: For now it remains a prototype, I have not decided yet what I'll do
best regards

hi alonso
Congratulations
Excellent device and without complications
As for me, I still have not succeeded in the first device manufacturing, is still the problem of discrimination
He works as a pulse induction
He also works with a transmitter as in this Annex video

Hi
I am not Alonso
I saw your video. I don't use your method

ALONSO PD ALL CONECTION
 

Hello Andreas do you have all conections?, when you put the interconnections of all the elements of PD to see where I'm wrong.

Already I conected all pd elements but does not work as I interconnects.


how do you see the image of the interconnections present here of the wires going to the receiving antenna seems that there are good?

what about the zero point calibration must be done first of all of the transmitting and receiving antennas if everything is connected directly and in conjunction with the ferrite? that is where I have the problem.

LRLMAN.

Need fine tune all coils a central frequency by Tx coil and next step zero all together. If you find the best point setting ferrite coil (this is so difficult), you must try find the place for Rx coil and ferrite together for same output signal via ferrite circuit and MD circuit. If you can see my first video i use screws calibration for finding the place. It's difficult, because need critical place +/-0,5mm up-down front -back for all coils
best regards

And what about the interconections of all elements?? are fine?? respect to the image???

I don't know how interconnected the TX and RX, for me it's not good the image, i have a problem mi PD not work.

And what about the ferrite?, how can work the ferrite? do you think if i make a short circuit with a 1.5 v, should detect it the ferrite? to know if this is working?

May be tomorrow I upload a video of my Pd Working.

Greetings.

LRLMAN.

All my posts are very clean. All my schematics are correct. Read again all posts and try.
Regards

OOOOOOOOOOPSSS,

I DID REVIEW ALL INFORMATION AND NOTHING, JUST I DID WORK THE OMEGA COIL, BUT I ASK IF ANTENNA FERRITE MUST ALSO BE WORKING?? I REVISED ALL COMPONENTS BUT I THINK MISSING SOMETHING MORE BECAUSE THE FERRITE ISN'T WORKING.

IN ALONSO PD IS EASILY TO KNOW WHEN THE ANTENNA FERRITE IS WORKING WITH ONLY MAKE A SHORT CIRCUIT 1.5 BATTERY WITH A ROUND WIRE 20 CMS. LONG, OR WITH A TELEVISION REMOTE CONTROL, BUT IN THIS NEW PD NOT HAVE ANY SIGNAL WITH THE SHORT CIRCUIT AND I THINK IF IT IS NORMAL ????

SO WHERE IS THE ERROR?

IN THIS NEW PISTOL DETECTOR I NOT SEE WERE HAS THE SWITCH POSITIONS ONLY FOR FERRITE OR JUST OMEGA OR BOTH.

ALSO I THINK THAT YOU NOT BEEN CLEAR ENOUGH, BECAUSE ONLY THE MEMBERS OF THIS FORUM ARE SUGGESTING ALL WITH IMAGES, WITH LEGEND THE POSITIONS OF ALL COMPONENTS OF THIS EQUIPMENT AND THE PROYECT IS YOURS AND IT IS NOT OF THEM.

SORRY ANDREAS.

LRLMAN

Hi LRLMAN
I build clone with all parts, all stages as you know and publish here.
Calibration is very-very difficult and critical
If you have not tune all together this PD cannot work.
i see clone can detect a spark only 40cm distance , a magnet near 50cm distance and ofcourse metals on air maximum 20 cm distance.
TV control i think detect 20 cm distance
Now if you want work with only feritte, if you want detect a spark xxx distance, this is your choice build it.
For me is a pratform for better results
About if i am clear or not
Ofcourse i am clear. ofcourse i publish my first unit here and i say this is a real clone with small mods for better stability. ofcourse i publish here a fine PCB for all members if they want build and experiment with this.
Now if you want method for full calibration or more, i think some members publish here can build this. In this case you can ask there
Now about PD only for Gold
I use only one preamp stage by clone alonso and new circuits by me (you can see my last photo inside PD only for Gold)
Pd only for gold cannot detect metals, cannot detect sparks, cannot detect magnetic lines etc
I am very clear. I publish here a thread "real clone alonso PD". I don't publish here a thread " how you can calibrate and build a clone alonso for your step by step".
In this case some extra infos via my posts is a gift for every one try build one
Best regards

Hi Andreas , maybe Now I understand what is Secret for this PD narrow band gold filter for very high frequency.

Regards.

this pd is free or for sale ?

Alonso PD is free to manufacturers or anyone who wants to try construct it.
My presentation of this PD was done in same box shape as much as possible dimensions is what properly, with the original schematic and very small mods for more stability. Of course I use the same box as "platform" for my PD only for gold.
After finish all experiments and anything need more, i put PD only for gold in a new design box . PD only for Gold is not free
regards

Ok Thanks
for users like me , that no have any experience in pd , build this pd is very hard
best way is by pd

Dear ANDREAS
how much the price you sell this pd

A fine circuit, need and special case, for ergonomic search and easy calibration by user. In this case i must draw a new box for put all electronics circuits, ferrite etc. I think after ten months am ready with new design circuits as you can see, my post #218.
I don't use the original PD box, because i don't like this classic design and more ,because i have problem with with vibration between base "coils housing" and main box.
Need only fine weather for external tests.
Inside lab PD can detect very easy Gold if put a place after 30 minutes. Very delicate unit, produce a "trust" by user via calibration and see with eyes the real detection Gold.
Need small time for solve all small problems
enjoy

Very nice looking instrument, and it's tall (like TOTeM). However, the handle on your PD is better positioned for stability. :)

Many times i have in my thought your design-box, because is stronger for use and better protection coils vs vertical setting ferrite.
You are right. If you think my design-box make a "confused" or you think... i make it without your license, please inform me for change it.
I like the clean solutions and i don't want make any problems

Hi Andreas,

Absolutely no problem with your design. There is no conflict with TOTeM.
I was just admiring the way you repositioned the handle for better stability.

Very nice looking instrument, and it's tall (like TOTeM). However, the handle on your PD is better positioned for stability. :)

Well as for the center of Gravitate if the handle is in the center and not in the face is so easy.

Not be worried Andreas do as you like without recourse to the permission. I even thought to divide your box into two, but you did it before me. OPS Then again i need ask permission from you.? I know you not give it purpose I build it without problem .... thank you Andreas this is life :D:D

Just a question
 

Hi Andreas
What's New on your machine Are there videos Are Showing copies of it for sale

an electronic design engineer told me to get on the frequency 60 kHz.. 65 khz ,l8 50 turns and l8 350 .wire 0,20

what you guys have to say about it?

I would like to receive greetings Andreas pain pda device just does find gold or Other precious metals also sensitive Can you give me information on what is the price? thanks

With full sensitive today i detect the dcf77station from 40 km distance :lol::lol:

nice work ANDREAS, i like it

can you put your new pcb for us here to try it? :frown:

Hello Andreas.
I tested my PD on real object from 4 years ago in 2m depth.
It can detect signal from 7 m away from target .
See it from here.
http://www.felezyaberoj.com/?p=4372

LDX FOR GOLD
 

LDX is designed for gold but it can detect other materials like LEAD too.
You can see my test from here.
Also i tested PD,Mole prospector,ldx with the same results
LEAD is about 5kg in 2m depth and from 4 years ago.
http://www.felezyaberoj.com/?p=6796
thanks for your cooperation and helps

Is LDX static field locator like zahori
or radio frequency reflections like PD
or termal locator like LZR kaabi

PD
 

Dear Okantex
1and2 close but not the same. In addition there is earth magnetic comparator for better results

So simple only small transmitter underground can produce signal for long range detecting .
ROJ ,don’t worry :D:D:D

Movies contain Proof for long range detectors , first must detect target , second while camera on dig and show target and again show the empty hole without signal . ;);););)

See it again.pls
the level of the signal starts to increase gradually from7m away from target
when the device is exactly on the desired object the sound disappears.

Dear AFT.
You are right,but but we want to share our test ONLY.

ROJ , personally I don’t any problems with you . happy Iranian new year, happy Nowruz

PD
 

Dear AFT.
Thanks for your opinion and idea.
I will do more tests and let you know.
Max range on big object is about 20m and max depth is 6m.
My best wishes

Dear ROJ,

Since you have a Mole Prospector, it has proven near some appliances (refrigerator, TV) to see if it also reacts?

Using the Mole Prospector as sensor? is an elongated antenna?


You've opened?

regards

Edward

Dear Edward.
I have tested MOLE Prospector on WI-FI.
It reacts to wi-fi signals from 5m away .also it reacts to TV and Refrigerator too.
Warm Regards.

hi RO
JWell done amazing results Is it possible to share project images from inside the machine how much is the frequency

Nice design. Congratulations.

Pity, that it can detect mercury fillings in your teeth only.

Hi everyone
I made this circuit. When the battery is connected to the circuit The red LED lights up. What is the reason?
can i use it when this red led is on?

Possibility
 

1.2 nf = 122
0.6 nf = 601

or

1 nf =102
0.8 nf =801

If you can not find this range of capacitors
You can remove the old radio
