Hu!!! I feel trembling!

[Seden]

Esteban,

Well your getting warmer (ah no pun intended). You need to go down to 1.2mm for gold according to the careful experiments of the German Physicist Dr. Paul E. Dobler. I've looked into building an antenna using printed circuit board technology but I don't know if it can be done (Carl, whadda think?). I know their currently using the method used to lay down the traces for IC's for various mm antennas,hmm.

I've also gotten books on Spectroscopy and at the light frequencies your looking at Molecules if I'm not mistaken,Carl would know. I've also gotten a rectifier tube that is doped with radioacitve material that some Amatuer Radio Operators have been using for 100 GHZ that might be able to detect 1.2mm as it's around 240GHZ I think. Been awhile since I looked into this so that's why I'm unsure but pretty easy to convert 1.2mm to Frequency.

Dr. Dobler found out that these frequencies can travel more than just a few cm. Check out the British StarTiger project and the pics I've seen where the Russians have a mm camera mounted in a tank and it showed what a mm photograph looked like of underground objects from a several hundred feet away from the tank-very cool technology!

How is the lenght in mm of IR light 940 nm? Is 9.4×10-4 mm. If you transmitt IR light, for a "strange" motive the phenomenom "walk" in the light and detection occurs. The IR method is one of the more effective and precisse I have experimented, and laser IR will be better in distance. This IR light must be modulated in low frequency. So, this is a "train" of short antennas. Simple: if you can transmitt audio, voices, etc., via IR, also of course you can receive the "phenomenom".

In this theme I have some question for people in this forum who knows more than me regarding electronics.


This is one of my IR projects:

[Geo]

Hi Esteban:) . What is this? Tell me more i believe you.
Qiaozhi don't believe :p at these devices (sorry Quaozhi)
Regards:)

[Qiaozhi]

Hi Esteban:) . What is this? Tell me more i believe you.
Qiaozhi don't believe :p at these devices (sorry Quaozhi)
Regards:)
You are correct. I do not believe. :p
But I do respect Esteban's efforts at experimentation. Who knows, one day he may prove me wrong. :)

What I don't like is empty rhetoric, and pictures of men standing in holes with no treasure in sight. I also do not believe when I see someone proudly displaying an item that was claimed to have been dug up from some ludicrous depth. The chances are that it actually came out of their own pocket. :eek:

Esteban - please keep at the experiments. I truly am interested. Even though personally I'm staying with known good technology and standard scientific principles, not made-up pseudoscience. :D :D

Esteban:
"Simple: if you can transmitt audio, voices, etc., via IR, also of course you can receive
the "phenomenom". "
Yes you can tx MODULATED audio via IR......on very SHORT range. Other words TX and RX should
be very close....few meters but NO MORE!
On RX side you should have DEMODULATOR....
THERE IS NOT any ANALOGY in this (IR principles) with any kind of long range detection..?!
How, the hell, you gonna detect any kind of metal with IR ???!??
Esteban, you put eneormous effort to acquire something....but with very wrong idea..sorry!
Seden, those ultra high freq. can not penetrate in any material. Also have very short range,
other words need ultra-high power TX to reach some range, also need visibillity between TX and
RX points...etc..etc...
For example try to examine SAT equipment and how it works....

Esteban:
"If you transmitt IR light, for a "strange" motive the phenomenom "walk" in the light and
detection occurs."
Very WRONG! "Detection" occurs only when you "walk" in the line between TX and RX and "brake"
continous reception of RX......thats how some type of "walk through" IR detectors works.....
There is a type of industrial IR "detector" usually mounted on some product line in purpose
of counting products.....nothing else....
Also you may build simillar and put at your front door...so when person approach to door,RX
receprion will brake and alarm can warn you inside the house...just an example...

Quiaozhi: "It will never work."

Yes! Of course! It will never work!
Esteban, looking at your pistures here...huh! Again FM radio (cheap,unstable one) very funny
connected in very funny "project".....
Also you used ordinary photo transistor as "sensor"...? Detect what??? Light?
Esteban do not waste your time with those. Since you have very good will to experiment,than
why dont you take some already proven IB MD project and further experiment with it. At least
you may gain better performances by experimenting with it.
If you continue with this subject, you are in a danger to complete loose yourself in those.
You gonna spend years in those without any success....
Also you are in a big danger to fill up you head with a lot of prejudices about this stuff...
Somehow, i feel very sorry for you....


:( :( :(

[Esteban]

I want to follow your advices :) , but my knowledges on certain topics do not allow me. If you want to limit me... you're the wrong! :D

Of course, also I build IB machines, two boxes and others. Fu!!!! since 25 years.

Esteban:

Te propongo que no dejes de investigar sobre tu idea !!!

Hace muchos años parecÃ*a que el espacio y el tiempo eran absolutos, hoy eso ha cambiado y es la velocidad de la luz lo que parece ser absoluta.

Aun cuando tu objetivo no se alcance estoy bastante seguro que muchas cosas nuevas aprenderas y sabe Dios a que conclusión llegarás, vaya talvés tu método sirva un dÃ*a para curar el cancer... entonces habrás llegado a un resultado mucho más importante que descubrir el más valioso de los tesoros.

Los buenos resultados son de los que persisten y experimentan cada dÃ*a, perfeccionando los metodos y refinando cada meta.

Creo que nadie tiene tanto conocimiento como para tener la verdad absoluta en sus manos, por eso cada persona tiene el derecho y la posibilidad de llegar a un resultado que nunca se haya visto.

He notado que llevas mucho tiempo estudiando y experimentando cosas sobre detectores, no nos queda más que esperar de usted un resultado muy interesante, tengo confianza en que lo obtendras... talvés hasta más pronto de lo que usted mismo supone.

Saludos

Diminute, gracias por tus palabras. El que no quiere ver. no ve. Pero el que intenta ver, puede que alcance a ver algo... :)


Diminute, thank for your words. The one that does not want to see, it does not see. But the one that tries to see, maybe see something...

[Seden]

Diminute,

why are you masking your message in Spanish so the rest of the forum readers can't understand it?:eek:

This forum is for English as it is the universal language and frankly I would like to enjoy reading what you have to say as a forum member.

Gracious Senior

Randy

[diminute]

I wrote my post in spanish cause it was direct to Esteban,

Esteban read spanish very good, but i'm sorry my friend...

All languaje are important, not only english.

I refered to Esteban that he continue your investigations, he is showing some result to us, but some people here believe that they have the absolute truth in your hands. No body has this privilegy, only Got.

There's at this forums much more message with offensive significant that the my. I respect everybody here, i consider my friends for all you.

Sorry for my bad english, Esteban can traduce my msg to him... he has the hability to write in both languaje.

Thanks for all, diminute

[Seden]

Diminute,

Please don't be shy about your English skills as we've got people from Europe on this forum I'm sure struggle too but us English speakers appreciate any attempts and will not look down on you. If I were to join a Spainish speaking forum you'd best believe I'd be using the Google Babel Fish for translation both ways if I had too.

But I am proud of Esteban for all the circuits he's built and tested. I love designing but HATE building circuits. I guess it stems from the my early years in the electronics industry when first starting College having to wirewrap and point to point wiring in an Engineering Lab,really burnt me out and somehow I've got to get past those bad memories so long ago.

Esteban I will freely share with you and everyone else what my next project is cause I don't care about making a product out of it (LRL MFG.'s take notes). I've found a company that still sells paints made from Zinc Sulphide and Zinc Sulphoselenide called Winsor-Newton. As you all know Zinc Sulphide was used in the early Crt'S and it responds to IR. Just for fun I'm going to paint it on the face of a Phototransistor and place 1.2mm wires in a square pattern (read at right angles to each other),place it in a small black plastic light proof box and see if I can detect the extremely small voltage nodes on the full wave dipole-ditto for the Zinc Sulphoselenide that responds to varying electric fields that would not create a high enough voltage to be visible as it takes alot for this material.
Yeah this is a long shot but why not? I'm also going to try putting a doughnut magnet to see if that makes any differance.

Another experiment that would be interesting would be to use a neon bulb doped with Radium paint scrapped off an old watch to encourage it to fire in the current starvation mode.
I don't know if anyone has seen the article by Dr. Harry E. Stockman in the Feb.1980 issue of Ham Radio, but he was the one that introduced using a neon bulb for a Ghz receiver complete with schematic (type in "Plasma Diode Experiments"on google as that was the title).
Then an australian Ham VK2ZAY wrote an updated,improved version in the article "Plasma Diode Detector" complete with schematic as he had trouble with the hiss noise that the current starved neon bulb produces.
And my last idea based on Dr. Paul E. Doublers book is to make a either a PCB yagi or Slot Array for 1.2mm and couple it to a pressure sensor. The most sensitive one I can think of right off would be a air dielectric capacitor that is sealed and has a thin plate on the side that faces either the dipole or slot antenna feed.

I welcome your comments as these are "seat of the pants" ideas,

Randy

"...This explanation (?) nothing to do about what I want to said. Sorry for you ..."

Ha,ha,ha !!! Whenever you meet REAL FACTS, you have simillar nonsenced answer!?
So, what ,the ****, you wanted to say at the first place????
So much claims,nonsences....at the end NOBODY UNDERSTOOD AT ALL YOUR POINTS???
What is your point? What are you trying to explain here?
For example here is your post:

:D :D :D

[Esteban]

Radiation source can be detected via compound zinc sulphide.

Regarding the article wich describes a neon lamp for to detect high frequency, is possible to found modifications. Here two files I had since some years:

[Esteban]

This is the proof you never learn nothing: Of course, if I transmitt a tone via IR, for example, in few hundreds hertz, so this is modulation, sorry your engineering "knowledge" is very far to me! :D Who are your "professor" or you never learn the lessons? :eek:

[Seden]

Esteban,

I really appreciate you posting those two articles. I had seen the one about the scalar detector but I guess I threw it out. But that's where I got the idea for the ring magnet and I meant to say that I was going to put the magnet around the neon detector,not the photodetector. But I had never seen the article on the phototransistor with the ZnS painted on it-I didn't think my idea was original darn it. But good information that will be put to use.

If you come to the US I'd want to meet you. I live in the Los Angeles area by the way.

Also ignore the people that are giving you a hard time,this is supposed to be an Adult Forum for sharing ideas (read free thought and speech).:confused:

Randy

[robert]

:rolleyes: :rolleyes: :rolleyes: :rolleyes:
Yes,of course!!! Like hell!!!

Let's say 455kHz to 460kHz!? So we can use it as remote control...same way?!:rolleyes: :rolleyes: :rolleyes:
Ha,ha,ha,ha!!!!

Be serious! Cant you read what this thread is about??? What the hell you are talking about?

You mixed up everything!?:rolleyes: :rolleyes: :eek:

I wish you very luck!
:rolleyes: :) :D

[Esteban]

OK, Randy, thanks very much.

Found a paper for detection at THz region. See the tip in contact with the positive electrode of photoconductive THz emitter based on GaAs, this is base of simple IR leds. Coincidence?

[Seden]

Esteban, That article is just what I needed,thank you for helping me. Have you had a chance to get a copy of Dr. Doblers book? The original's are in Deutsch,but you can get an english translated somewhat condensed version from "Integrity Research Institute" for $10 which is 45 pages and worth every penny. It also contains additional information at the beginning of the book. The url is http://www.users.erols.com/eri/page6.html .

Robert, where did you come up with this 455KHZ stuff. Who's working with old radio IF's? Me,heck I'm shooting for 249GHZ,care to join in? It's kinda a put up or shut up propositon if you catch my drift ;). Now how about contributing practical design ideas so we can make some progress here. That's why Carl has gone to the trouble to put up this forum as an medium of exchange of ideas-cool no?
I seriously would like to know how you would go about this goal that Esteban and myself are trying to achieve. I am NOT designing a MFD or LRL but a simple hand held detector exactly like the Falcon MD-10 that is an IB 300KHZ detector that unfortunately works for hardrock mines-not Alluvial deposits. Kinda a poor mans XRF if you would that is tuned just for gold.
The Falcon has a handheld probe that has a distance of about 1-3" but cannot handle the black sand in the Alluvial Sand so enter the Millimeter detector that you can walk along and take readings from the soil directly in front of you. Ditto for the walls,just hold it close and walk along seeing if you can detect gold in the matrix. You up for the task?

Randy

[goldfvr]

Randy, how far away are you saying this proposed mm device could detect lode gold ? what could be done to achieve a distance considered "remote" or a couple of hundred feet...

[ivconic]

:confused:
Think twice!
Robert made good points there.
Almost every experiment with IR failed so far....Wasted time!
regards
:p

[robert]

:rolleyes:
"Robert, where did you come up with this 455KHZ stuff."
Seden, you should read every post here carefully;
Esteban: "...in few hundreds hertz, so this is modulation, ..."

"..Who's working with old radio IF's? ..."
Also remote control ceramic filters...Besides,did you payed any attention on
Estebans posted pictures so far?
What can we see on picture above???
"Me,heck I'm shooting for 249GHZ,care to join in?"
Yes! Why not!? But i do not have a clue how to use that freq. in metal detecting???
Not to mention Long Range...ts,ts,ts...
"Now how about contributing practical design ideas so we can make some progress here."
Again, i am very sorry, i do not have a clue....but i do know what is possible and what
is NOT!
"That's why Carl has gone to the trouble to put up this forum as an medium of exchange
of ideas-cool no?"
Carl became already my IDOL! Dont you worry about that!

"I seriously would like to know how you would go about this goal that Esteban and myself
are trying to achieve."

Huh! I already argued with Esteban many times,but this does not mean that i do not respect
him and his efforts. No,not at all! I do respect him a lot.
Our posts are just usuall rethorics, when no good idea is present...Nothing to worry about.
".....Falcon MD-10 that is an IB 300KHZ ...."
Although it looks to have very poor performances, it would be interesting if you post some
picture of it here.Also any technical about it...so we can see what is all about.Better if
you open another thread about it....

"...but cannot handle the black sand..."
Of course! Speaking of high frequencies....ts,ts,ts....
"...You up for the task? "
Tell me what to do, i'll be glad to contribute here....
I do know that high frequencies are not suitable at all for this subject. Does not penetrate
in any kind of material at all. Not possible to build detector using those...
Reflect/deflect from any material....What to say? I had pretty hard time when worked on
repeaters once....History....i do not wanna bug here with those...
I am just sorry to see Esteban (with enormous will) how to torture himself with nonsences,
while he can do much better...much,much better...
If want to make long range (deep penetration) better to stick to magnetometers or some
georadar...as much as man can gain so far...
Besides, Long Range... is very unfortunate mixed up term....Whenever i hear that,reminds me
on Bogus science&devices....
Carl was very smart when named this part of forum like that...think twice! Bravo Carl!
....
I am here.I have good will to contribute. Tell me how?
But every time i see nonsences...i will react in my already known manner...a kind of
contribution too...

Esteban,friend...no hard feelings!
Best regards!

[Esteban]

Yes, if you pretend show temperature in display. Is this the only way you know?

Who tell this? What is every? Do you have negative inputs about it? Do you investigate in all source today we have near our hands? Or only you suposse it?

[Seden]

Esteban,

I was thinking the same thing about people on this forum who haven't yet come up with a better idea to try but can only make negative comments. I think this fellow has been found out.

I was looking up various searches for millimeter detection (bolometers,radiometers,etc.) and of course came up with alot of demining sites,one of which showed how easily it is to detect them with an Infrared Camera at night.

I found a really excellant paper put out by the U.S. FCC entitled "Millimeter wave Propogation:Spectrum Management Implications",Bulletin Number 70.
This document is packed with so much easy to understand information with alot of charts showing attenuation vs frequency and conditions. Turns out for 250GHZ for dry conditions the attenuation is about .48db per km and about 5db with humidity in the air. Far as through soil for passive detection it looks like about 3 inches is it. That is identical to the Falcon MD-10 that can be EASILY found using google,so I'm happy with these parameters if I can cobble together a working system however crude it may be compared to the big bucks university with the Phd's designing and building them.

Robert old chap,you asked me what I wanted you to do and all's I would ask-no beg- is RESEARCH millimeter technology so you can get an idea of the limitations and capabilities. In the above post I gave a specific title of a cheap booklet by Dr. Paul Dobler from the Integrity Research website. Also do yourself a big favor and type in StarTiger into google and study up. I think your testicles will drop to the ground when you see what the British Aerospace industry has accomplished complete with photographs.

Good hunting!

Randy

[robert]

:rolleyes:
Yes Esteban,i did a lot of research on that field.It will take pages for me to explain to you and Seden about all problems occured in that matter...
It is much easier for me to simply tell you to give up and do not waste time and space here....no benefits from those at all in metal detecting.
Cant you distinguish what this forum is about...once for all???

This is metal detecting,prospectors forum man!!! Everything elese is not important and not relevant here!

You rather stick to blah,blah and a lot of philosophy than to "ground" yourself and try to do something real for instance...

You do not look smarter here cose talking about "high" scientific fails...
Everybody can use google and search for simillar texts and later post here like its own presumptions....not smart at all!

Life is to short for me to bug myself with nonsences you ve been talking here!

Come on with real idea/project,than we can talk about....

You are loosing yourself in "clouds"...come on the earth and be real!

Like plain amateur, nothing you can do interesting enough to "shake" the world of md...

Be real for once.

Seden you are on the same track as Esteban. I wish to both of you much,much luck!
regards
:rolleyes:

[Esteban]

The only who wasted time here are you, because you loose the time in the reading. :D And the space is not yours! Deppend of the Administrator. If he is against all this, well, we dissapear!

Please, no more Byzantine discussions. Only focused in the posibilities, no in the negativities.

Randy, thanks for the info. I tell you IR is a great field! I read in physics books that all no natural buried bodies (the creates for the man) emits IR, the metals in more high quantity. Remember: gold loves IR. I have this paper: Microstrip antenna-coupled infrared detector.

[Seden]

Esteban,

I was looking on http://64.143.63.33/pdf/coatings.pdf
and on pg. 5 they show the spectrum Graphs for Gold and Silver and radically different. Gold is at 95% at 900nm and 98% at 10um whilst silver is 95% flatline from 600um to 2.0mm. You can buy a inexpensive Far Infrared bolometer that covers 8-12um which is around what 80 to 90 degrees farinheit? I have one at home that I bought from J.P. Marlin mail order (type in google) for $3.50 I believe. It's been several years and there's also a company that has a kit that enhances that bolometer. If I can find it at home I'll post it. It's fun device to play with and so easy to use with a minimum of parts.
I know you probably know this but the trick is to get the biggest temperature differential between the ground/air and the gold in the ground like fall or spring at early nightfall.

I received a notice to pick up the Oscilloscope/Spectrum analyzer that I bought off ebay for a little over $200 from Hong Kong (on a very slow boat as I paid for it Oct.9th-thought I got stiffed and opened a case with ebay and paypal). So now I'll shift my priority back to a electronic version of a gold detector that I had mentioned earlier using the ULF range where you can see the differance in minerals due to their grain size (Natural Field Spectral Induced Polarization-google once again on this).
Also I just ordered a Radiometer for a whooping $10 and so will play with exciting it with Millimeter radio waves as Dr. Dobler did using a Printed Circuit yagi and trying a parabolic dish that you can buy from Edmund Scientific for a song (American slang for low cost-dates back to the depression era here).


Ok,Robert what do you think of my shifting from MM Waves all the way down to ULF-TRUE SCIENCE or buh sheet (American Negro slang for a lie)?
Or a you just the preverbial Jokester here on the Forum? By the way old bean, I'm interested in some of your metal detector designs,care to share them eh? No talk now-just show me the schematic.

Randy

ha,ha,ha...

No one is trying to limit your nonsences at all. Come on, be my guest and post more funny nonsences Esteban....everybody laughs on you already...

Ha,ha,ha...

"Gold love IR...." ???? Ha,ha,ha,ha,ha.......another joke????

please continue...!

[Carl-NC]

Well your getting warmer (ah no pun intended). You need to go down to 1.2mm for gold according to the careful experiments of the German Physicist Dr. Paul E. Dobler. I've looked into building an antenna using printed circuit board technology but I don't know if it can be done (Carl, whadda think?). I know their currently using the method used to lay down the traces for IC's for various mm antennas,hmm.

PCB traces down to 0.1mm aren't too difficult.

I've also gotten books on Spectroscopy and at the light frequencies your looking at Molecules if I'm not mistaken,Carl would know. When you burn things, the light produced has spectral signatures that can identify the elemental makeup. Not very useful in treasure hunting.

Check out the British StarTiger project and the pics I've seen where the Russians have a mm camera mounted in a tank and it showed what a mm photograph looked like of underground objects from a several hundred feet away from the tank-very cool technology!I've looked at their site, and wasn't impressed. They have very few pics and little explanation as to what they show. I would think that if the technology had value, and especially if their work had produced a lot of good results, there would be tons of info and pics there. But there isn't. And if you click through to the ThruVision web site, it is a whole bunch of nothing.

Esteban, That article is just what I needed,thank you for helping me. Have you had a chance to get a copy of Dr. Doblers book? The original's are in Deutsch,but you can get an english translated somewhat condensed version from "Integrity Research Institute"...

Ouch... I've run across the Integrity Research Institute before... ironic name, considering that Thomas Valone (Director, President & Chairman) bought his PhD from a diploma mill. I wouldn't give much credence to anything you find on that site.

- Carl

[Esteban]

Randy, you're not thinking with the necessary uniformity they want... If you are out the "structure", you're lost, my friend! Please, leave this good persons prepare the correct way... They only want "the better" for you.

[Esteban]

Sorry to say;but there are at least dozen of my projects,right here on this forum.... Many people used alredy....Of course i used another nick to post some posts here and other forums on the internet...

Show us one. If you can, :) good! If you can't, :( also good! :D

[robert]

"...I wouldn't give much credence to anything you find on that site..."

This is the POINT!

Esteban,i do hope that you'll beleive Carl on this...since you do not beleive me at all...(it showed so far)..

The very same case with a lot of simillar txt's you may find on internet.

About projects...you already used some of them...
It is just my decision not to mix my several nicks one with another, due to integrity....

[Seden]

I typed in the following quote "millimeter wave camera" on google and got many hits. The first one re:TRW's camera is
http:www.spie.org/web/oer/march/mar97/passivemm.html and lockheed Martin's site is http:www.brijot.com. There's also a camera called the "Bolocam" that a University in Colorado is working on try that on Google.

Robert my Albanian critic,please check these sites out and see if your eyeballs roll to the point of facing backwards,then come join in on the research and development effort with me. I need your experience to pull this off (actually I'd rather have Carl's since he appears to be the only real Engineer joining in on the discussion but many hands make light work).

About projects...you already used some of them...
It is just my decision not to mix my several nicks one with another, due to integrity.... :rolleyes:

Please, for example, wich of your project I use. I'm skeptic :rolleyes: at this point. I don't use your projects!

[Seden]

Esteban,

Have you checked out the site with the IR reflectance of Gold and Silver? I'm thinking by getting the bolometer I mentioned it would be out of the range for silver,but I haven't researched the spectral response of other metals.

I have my 5 days off coming this Friday and will now be able to place various metals in this plastic tub with iron rich dirt-pulse it and note their phase vs frequency response as well as spectral response.

Looks like Dave Emery is within months of releasing his "Pulse Devil" and I wish I had the ~$2500-$2900 to buy one. The rich nugget shooters are going to vacuum up what the Minelabs missed and so eventually you'll need a D-9 or a tractor with a scoop to reach the gold!

Since I don't have the bucks I'll just build a simple PI TX with and beat the lo against the return signal for added depth. Have you tried this Carl?

Robert my fellow Technician/experimenter colleague, I have been posting on this forum darn near from the beginning. Mostly lurking as I was spending most of my time studying Geophysics and Geology and didn't have time to play with designs. Have you played much with PI designs? What do you think of the idea of CW vs AM detection? Have you ever tried it? Seems like it would work much better than straight AM detection.:p

Randy :flag_de: :flag_us:

:D
It seems that Carl has something against my previous wish
and intention to distinguish my nationality.
Randy,first of all i am not Albanian, i am Serbian...I am,
kind of sensitive on those things.Sorry,but i would like to
keep some facts clear.No big harm done,just i need to clear
this up.
Carl if you have something against that, thats your problem!
But you should be honest and let me to clear up those, not
to delete my posts, while Seden's post remained undeleted?
( "...Robert my Albanian critic...")
As time goes by i see so few reasons to be here any more!
Mainly thanks to Carls onesided honesty/fairness.
Yeah,yeah...i know! Carl,you gonna repeat all the "brain-
washing" rules of this forum.....
But as man can see here very few posts are tightly stuck
to subject at all. 99% of posts are widely filled with
various rethorics and philosophy.
I DIDNT SAW YOU,CARL DELETING OR WARNING THOSE!?
So dont you even try to explain again reasons of your behavior!
I can live with fact that this is your forum and you gonna
do whatever you want here....nobody can stop you!
So after finishing with Seden, i'll spit on you and your
forum and leave for good, on great Estebans&others joy!!!
Esteban start to celebrate from now! No more RObert here to
bug you! Kiss "dear" Carl for that, your good friend!

.................................................
I'll be off this unbenefitial place for good. But i do not
want to "cut off" your questions Seden. I would like to
answer on those, but first try to define me more preciselly
what did you asked me;
"...CW vs AM detection..." What do you exactlu mean by this?
Define me CW detection and AM detection first, than i'll be
glad to answer, even help if possible.
"Have you played much with PI designs?"
Yes Seden! I did a lot of those so far. Mostly relying on
Eric Fosters projects/knowledge. Eric showed as very
conversant,expert and also a great human,always good willing
to help,teach and tip....Thanks to his explanations i learned
so much about pi detectors. Tribute to Eric Foster! And many
thanks to him!
I also tried several other PI designs, some of them very nice.
I can not claim here that i am expert, but for sure
i feel very conversant to talk about those....
One more thing. I even tried to build Carl's Hamerhead PI once!
Catastrofic project! Amateur,stupid,non-working nonsence!
"...Carl's since he appears to be the only real Engineer..."
If Hamerhead is all he can do so far, than i feel very sorry
about his wasted years! "Real Engineer"??? Ha,ha,ha!!!
Like hell he is!!! Ha,ha,ha,ha!!!!

"I was spending most of my time studying Geophysics and Geology.."
Indeed very good news! Very good for you! I salute that!
But you should know by now that some scientific principles are
left for good.....for example those you've been talking about
earlier.
Just define me CW and AM (detection) and i'll be glad to
talk about.

Please stay off mixing radio "detection" usually met in radio
technique with any kind of metal detecting.
P.S.
Since i am not gonna come again here,Seden you may use my
e-mail to continue this subject;

Hi Randy

Yes, I check it. I read this info and other papers. IR emission is common for other metals, not only for gold and silver. Copper is great emitter.

I'm planning to build "IR camera" based on IR receiver module of TV, etc. I make some preliminar experiment and found there are regions in the soil wich a type of signal, in concordance with other medium range detector (microvoltmeter and others).

Seden, sachen, die Sie sich mit Robert besprechen möchten, sind eine intrersting
spitze. Sie können verwenden Deutsche sprachenhier schuld die tatsache, daß
anderes die leute, die anwesend sind nicht sie verstehen kann hier! Sehr gut,
wenn wir diesen freien raum weg von den nonsences halten möchten! Inhaber dieses
forums bereits gezeigte unfaire, unhonest behandlung gegen einige mitglieder hier.
So wird sie sehr gut sein, wenn wir Ihre fragen über deutsche sprache besprechen.
Alles, das sie bitten möchten, kommen und bitten. Ihre fragen werden beantwortet.
Respekt!
P.S.
Bessere weise soll seine e-mail benutzen. Er bat mich, dieses auf deutscher sprache
zu übersetzen und pfosten hier. Ich kenne Robert während einiger zeit. Er ist nicht
schlechte person. Aber er hat sehr "harte" art des argumentierens mit leuten. Versuch,
zum von von aufmerksamkeit auf diesem nicht zu zahlen. Auch er ist hölle von einem
experten in den themen, die Sie interessiert sind, also, wenn Sie mehr wissen wünschen,
ihn fragen und sachverhalt und wissen warten. Ich mag nicht mit die weise, die Carl
einiges beschäftigt hier bevölkeren, aber, hallo das leben ist!
Respekt


Again "big boss" showed his power here!? Bravo Carl! So few reasons for you to be
proud....
"..But as man can see here very few posts are tightly stuck to subject at all.
99% of posts are widely filled with various rethorics and philosophy..."
This is THE FACT which nobody can beat! Truth! If we accept this as fact, than i do
not see reason why should only Robert's posts been deleted here???

Carl your reasons doesnt make any sence;
"...amounted to nothing but taunting...."
Where did you saw taunting in this???;
Roberts deleted post:
"...Esteban, you forgot what you started here?
What is best (should be "better") than whos Raven???
What you posted above has nothing to do with any "Raven" at all!?
What was you idea at first place Esteban?
On your posted photos, man can see ordinary (cheapest one) am/fm radio,
connected in some strange design...??? What is all about?
If you want to be taken seriously, you should explain in details what is
your device??? Part by part...
What is elementar function of every stage in overall design?
Step by step.
You should post partially schematic,points of connection with that radio.
What you used in it? Where did you put input from front end?
Did you used local osci.......simillar?
How device is acting? "Beep"-ing, "Hum"-ing, "Scratch"-ing ...????
How can you distinguish between "detection" and "no detection"???
What can you "detect" with it?
Distant stomach gas,viruses,metal, maybe local station...????
Be serious man! Look at other threads how serious people explained their
projects, and do like they done.
Than we can even take a part in your "research" and maybe help you.
Until than...you can only gain laugh from others...Sorry!..."

Since Esteban started this sad thread named "Best than your Raven", posting
photos of his funny and strange project, it is quite natural and normal
to expect questions from other interested members about posted material.
Isn't that so Carl???
Esteban should take responsibillity and answer on questions here, since HE
started this thread!?
Or you,Carl, are aproving that man can open a thread and post few photos without
any explanations. And also anybody can come here and claim any nonsence
without further explanation!???
Please,Carl explain here this? Try to clear up, once for all, what is proper
way of acting here??? Which people can taunt and wich must not?
You mentioned taunting??? Let me remind you on some sentences here:

Esteban:"Hu!!! I feel trembling!.."
Esteban:"This is the proof you never learn nothing..."
Esteban:"Who are your "professor" or you never learn the lessons? "
Esteban:"The only who wasted time here are you, because you loose the time in the reading"
Esteban:"Randy, you're not thinking with the necessary uniformity they want... "
Esteban:"If you are out the "structure", you're lost, my friend!"
Esteban:"Please, leave this good persons prepare the correct way... "
Seden:"Robert my Albanian critic..."
Seden:"Also ignore the people that are giving you a hard time..."

Of course, almost every Robert's post has taunting also. I do not need to repeat all
those.We all already know about his specific kind of humor.But if we accepted that
as something we can live with, than why deleting ????
Or, why deleteing only Robert's taunting,why not every others???
Carl think twice! You made a mistake! Either you gonna have same rules for everybody,
either you just leave things as they are and only delete "name calling" and "bad" words.
Very bad situation. I liked this forum at the begining very much. Met many real friends
here, new friends.
"As time goes by" so small amount of good informations here,day by day, worse and worse!
But nonsences,missinformations,pseudo-science,lies more and more day by day!
I am sad to say but this forum is to be busted soon if continue like this!
We are different people.Every of us has his own reaction on nonsences. I do not reply
to much on nonsences.Robert is different.He simply can not stand to see lies and
nonsences. His problem. But i can see some benefits from his posts.
Asking questions,provoking to gain more informations for everybody to have here.
If we just sit and let everybody to post here any kind of nonsences without checking,
questioning,peaking and a bit taunting...than what should be the benefit from this
place??? Nothing! All informations and missinformations mixed up togather, on a pile!?
I do not have anything against, if somebody taunt me a bit,make joke on my account,
as far as i can get some benefit from that...
As i see, Esteban (attacked by Robert here) is not complaining much. As i presume,
Esteban is not angry on Robert also.Which is good and shows Esteban's good character.
I respect that!
Also Esteban is not illiterate and can protect himself, no need you to protect him Carl!
But....what has been done by now, is done. All we can do is to hope that this situations
never repeat again.
regards
:o

[Seden]

Sony, für den freundlichen Rat danke. Gut, dieses über Robert zu wissen, ihm mein apologie für Sein geben, also zu ihm bedeuten.

Has anyone on this forum ever tried pulsing metals in dirt and looking at the frequency spectrum and phase? I find an interesting study and this is already done by a Geophysical Equipment Mfr. but using a swept frequency I believe . I saw the results on a de-mining site how they could identify the differant bombs by their change in phase and amplitude vs change in frequency. From memory they started about 100hz and went up to 10Khz.

hi esteban
google " leningrad 7"
this is a light meter.visiable light is380nm -700nm
seden says gold is around 900 nm.
can this device detect gold.
I heard a man finds gold with this machine from distance like 100meters.
his last hole was 16meters and aim was to achive 20meters to find target but stoped because of some reasons.

[Seden]

Okantex,

I did Google Leningrad 7 and couldn't find any information on some guy using it to find gold,but there are several on ebay for under $20USD though.

I would like more information on this person please. Also I didn't say 900nm but 1.2mm or 249 GHZ was the frequency that gold radiates at based on Dr. Paul E. Doblers work in the 1920's. He basically used some of Dr. Bose's methods minus the photographic film-crude by todays standards but it got the job done!

Will look forward to any info that you've come across Oknatex re:Leningrad 7 as an gold detector.

Randy

[okantex]

hi Randy
as you say this device is sold as light meter.there is no claim say this can detect gold.
but a friend of mine say this device detects gold.
he saw this at a friend.and they went to some trips together.and his friends searched area for gold and pointed.but while using device he does not let somebody close to him.
my friend saw device from distance .and we searched a lot to find this device.
user of this device is known because of his finds.he is rich.he found few big founds according to my friend.

http://thunting.com/geotech/forums/images/icons/icon1.gif Gold vs Silver IR Spectrum
Esteban,

I was looking on http://64.143.63.33/pdf/coatings.pdf
and on pg. 5 they show the spectrum Graphs for Gold and Silver and radically different. Gold is at 95% at 900nm and 98% at 10um whilst silver is 95% flatline from 600um to 2.0mm. You can buy a inexpensive Far Infrared bolometer that covers 8-12um which is around what 80 to 90 degrees farinheit? I have one at home that I bought from J.P. Marlin mail order (type in google) for $3.50 I believe. It's been several years and there's also a company that has a kit that enhances that bolometer. If I can find it at home I'll post it. It's fun device to play with and so easy to use with a minimum of parts.

[okantex]

device only detects gold and copper

[Esteban]

The good conductive metal causes alteration in main beam of IR ray, but why causes this? So, modulated frequency (audio range, wich trave in the IR beam) changes his patterns in hertz and you can detect the metal.

The IR beam is very precisse, very pinpointing.

[Esteban]

Randy

Remember: IR actuates as antenna. The IR light (of a simple IR led, for example) ionizes the air and hot his way. With IR you can "see" (or detect) more. Here a example of how IR can show more:

Hi Okantex

I search for Leningrad 7 in the web. There are models Leningrad 1 to Leningrad 10. Leningrad 7 uses selenium as light sensor, maybe this is not very precisse in order to measure quantity of light near IR radiation, but the most important in this case is the sensibility.

But if you wish detect IR radiation from the soil, you can solve the problem with IR receiver module for remote control TV. This is into a small metalic box. I experiment with it and promises very much. You must insert into a obscure tube, no black, because this bright. Better is darken internal paint into the tube.

[Seden]

Esteban,

I finally found the supplier of an inexpensive pyroelectric sensor and fresnal lens. Goto: http://www.glolab.com and check out the specs on the PIR325 and FL65. Each item is $4.ooUSD plus shipping and there is a really nice applications manual for the PIR that you can print out.

Could you email me your email address? r.seden@sbcglobal.net

I have a new Mineoro LRL,and i want to talk about my experience with this machine.

[Qiaozhi]

I have a new Mineoro LRL,and i want to talk about my experience with this machine.
Please go ahead ... and be honest in your opinion of the Mineoro.

[Morgan]

With my respect to Mr.Damasio the inventor...
This test was made in a field where was buried 20 years ago a GOLD medal to test performance of TR/IB metal detectors...

[Morgan]

Before some people in Geotech Forum think or decide to buy any kind of LRL device,remember there is a place on this planet where there is GOLD buried some years ago,NOT TOUCHED FOR TWO DECADES!!!
I can´t say Mneoro not work,i only want to tell to Forum my experience with this device,and the results of more than a year of searching with this LRL...
Finaly i get my conclusions about DC2008,and decide to tell the performance of this expensive LRL.

[Morgan]

I was in Garopaba,very nice and peacefull place:)
For me its the new Tortuga,all pirates go there...To get the magic device to find the GOLD!!!
:cheers:

[Morgan]

When i was there,i know that people from Greece,Iran,and other countries go there to buy a Mineoro...Some of them are not rich and save money to buy a tool,not a toy.
Mr.Damasio is a very busy and inteligent man. I saw the factory,where they make many devices not only for TH.All this Mineoro people looks very serious and work hard.I test the mineoro in a special place near the factory.
But anyway there is something strange...In Tortuga,Garopaba field test for Mineoro...

[Morgan]

Tests in Garopaba was made near the Mineoro factory. I get clear signals on yelow PLASTIC marks were is suposed to have gold buried long time ago. If i touch several times this plastic marks i get more distance with mineoro ...

[Morgan]

The field test its near Mineoro factory.
I get clear signals 1-2 m distance,were is suposed to have gold buried long time ago. Over this buried objects they put marks,yelow plastic covers.
I get impressed with Mineoro LRL in factory field test,but...

[Morgan]

Yes,but if i touch several times this plastic covers i get more distance with Mineoro,because of the extra charge on this plastic covers over objects...
Mr.Damasio dont like this disturbs i make on field test,sorry for this litlle experience.
If i charge a plastic item with static,i can detect this small plastic 2 meters distance. But i´m searching for gold not plastic...:)
Mineoro its very sensitive to static electrycity,what about real gold buried long time ago? I can answer this question.

[Morgan]

The Mineoro device DC2008 was tested in this field many times during the year(where there is real gold buried long time ago,to test normal detectors),in most of weather conditions,unfortunly NO SIGNAL.
Other mineoro two box 08 MI,no signal,no metter movment over gold medal,but clear metter movment over 1kg coins buried at 60cm,with my withes TM808 two box i cant get this target,because ground mineralization.
Now i talk about DC2008 performance on beach...

[Morgan]

On the beach,maybe because salt water near or diferent ground condition i confirme this device become nervous in the presence of conductive metals ,not only gold,he starts beeping everywere ,become nervous machine,but unfortunly during this year i never get a clear signal like in Garopaba field test,and to find this targets on the beach i allways need nomal METAL DETECTOR...

[Morgan]

I´m sorry if i disapoint some members,but its the true about my DC2008,a broken dream...It seams to work but not as i aspect:frown:
In reality it detects GOLD with clear signal,large coin 20cm,jar full with silver coins 50cm,this is the on air test,small iron reject,big iron detect...Work like a weak metal detector on air tests...

You're completely mistaken on your statement above. You are actually detecting the gold object buried there not static electricity from this distance.
I was at Mineoro two years ago and also made my tests as you did. By that time the ionic fields were awfully low and weak. Even touching the covers I could only get a beep with my PDC from two inches away for THAT SPECIFIC target. From about 30 feet away I could get beeps as the ionic fields of all of those several buried objects summed.
You were lucky to get beeps from 2 meters away for a test target. Those targets are real as the objects are there for more than 100 years as that place used to be a spot for 'vaquejada' an old rodeo like type party.

What you trully missed was the opportunity to make them dig the object to give you as a gift as proof to yourself. I knew of an european who asked that and he took home a real old gold ring he detected.

[hung]

Sparzed coins are very different... Yes, is important that a 2 boxes can catch sparzed coins...

Hey Esteban, the 08MI is an extraordinary machine. Too bad I had to sell it 2 years ago to get a PDC. But now money is no problem.
But I don't want to buy the new ones. I love the old models with the red or blue circuit boxes. I always check the brazilian ebay to see if there's one for sale...:frown:

[Qiaozhi]

Thank you Morgan for your honest report on the Mineoro.
As you said, its "a broken dream".

If i charge a plastic item with static,i can detect this small plastic 2 meters distance. But i´m searching for gold not plastic...:)
To Carl - The test that Morgan did with a small plastic item charged with static electricity would be an interesting experiment for your FG80.

You did not set it right. There's a VU and a calibration for small objects.

A friend of mine has a MP10 2 box and I witnessed him detecting a small gold ring which as about 60 cm deep just looking at the VU for small objects activity.

Although the the MP10 is Mineoro's top of line 2box, the 08MI should work just as well for this.

Sure it does. In fact this is the 'means' which transports the ions for detection at long distance. This is true to all ionic/electrostatic Mineoro detector. But this is much different from what Morgan posted as his explanation for detection.

Yet more pseudoscientific gobbledygook. You have just heard some firsthand experiences from two people who own a Mineoro LRL. No-one here is in the least surprised to hear of yet another failure. The outlandish claims for these devices is pure fiction.

Modulation cause NF ion dancing (vibration) to be easily visible. It is about frequency modulation which you can get by reflected IR beam from small mirror hard glued at piezo crystal (piezo summer) driven by freqency changable signal generator (oscilator made by NE555).

The most efective is searching immediately after sunset cause of high ionic ground ingredients activity.

This is exactly right,,,, these devices use photoresistors, which are composed of selenium. And these dachas react wonderfully to the phenomenon. That's just the distance is not 100 meters, but a multiple of 10, this is my result so far. Of course, if you work with the receiving path, then you can increase the distance, the modern elementary base allows you to do this, without lenses. The only thing is that I personally don?t understand how to implement discrimination. It catches aluminum and all aluminum-based alloys very well.

This is exactly right,,,, these devices use photoresistors, which are composed of selenium. And these dachas react wonderfully to the phenomenon. That's just the distance is not 100 meters, but a multiple of 10, this is my result so far.
