Hi Morgan,
you posted that you can detect a 10eur cent coin and a small gold ring at 50cm in the air with PD, right ?
But you can just detect them at such great distance outside home, right ?

Please confirm or correct my previous assertions.

Now... if Andreas cannot detect a small coin at similar distance there's possibility that he cannot do that cause maybe tested inside home/lab, with metallic stuff all around.

Could be that way ? What do you think ?

Kind regards,
Max

Hello Max

Of course this tests was made out side home with no metals near the coil,and to get this results device must be with sensitivity in the limit(you must remember the teknik to do this) or you only get 30 cm air test with 10 cent...

Morgan..."only" 30cm on 10 cents is also great result.
Thanks God you didnt came here with "hudreds of feet". "miles...".
So i must be missing something here?
"Your device"...??? Where it is? Where is schematic? Pcb? Explanation?
Is that in restricted area? Only for (all) members, except Roberts?!
You know, without full posted project i simply can not accept even your
pretty modest and sane "30cm"....
So...poste it here not restricted or .....?

Hi,
Morgan posted already pictures of device, don't you remember ?

That was in public area, Mineoro thread... with all that photos of the thing...

Now even 30cm is very interesting result on the air for such small coin and small device. But he told us (again in public area) that device actually work on medium range (some meters) for long time buried e.g. aluminium.

look at thread "Mineoro 2-Box -- 492 feet range? ".

About schematic... I've posted whole thing on that public thread too... just look for it. The coils are missing cause I have no sure data on these.

But schematics seems have sense for some things.

Look at it now, I repost original version just for you ...contains errors but I was drunk when I made that!
Enjoy !

Kind regards,
Max

In the photo of new Alonso´s LRL device ,we can read VCA Electronica.
what is this,its some particular factory,or Alonso start making this devices with registrated patent?

This is main condition. First to be detected in air and second to be detected burried and covered with soil at 70% of air distance. Fair? Fair enough!
Second , device claimed to be LRL must BE LRL, not some "masked" DFX or Minelab or something simillar. Witnesses must check device and its composition skimly. What LRL? The same one "they" always claimed; radio IR,AM/FM,IF,MFM,Pseudo,Feriterod,ionic chamber,ultraviolet etc.etc. and God only know what else principle, BUT NOT classic PI, IB or BFO metal detector principle!
So.....there is a deal...
Like in the past, those miserable liers will :
1) Complain to administrator on my posts and provocations,
2) Stay off posting for a while,
3) After a while continue to polute this forum with brand new rubbish, same
lies and frauds but new names and labels...

So i dont really expect this to become serious. I rather expect administrator to step on their ("democratic") side again, like he did in the past.
Besides..my job here is already done!
I told to world who are mindless,illiterate ignorants, miserable so called human s....
I am spreading this story arround the net, on every forum. I do expect other sane mebers here to do the same. We should fight against evil....evil we met here!
Good bye!
Ah!!! The new directions in wich systems can't based electronic LRL!!! This is real progress!!!

I remember you lose the compass when you start talking about Shakira (uhh!!!), Santana, etc., in a lunatic thread (deleted, of course), "I'm bad, I'm nationwide"...

Admin has prerrogative for to banned any guy out of focus.

So when you asked him, old man told you at once the price - 3000e!?!?!?!
Very old but not senile ha..?
How come that all the trash you've been advertised so far here is very expensive comparing to real workable metal detectors?
Let me calculate....3000=2000 for old man + 1000 for me E.C. the great advertiser, advocate, lrl trash proponent and photos collector.

For 3000e...at least you could post some trash packed in some nice box. Or you just lost nervs and starting to "hunt" in a mud, looking for fast money?

If that piece of junk detect coin or ring at more than 2-3mm than i will jump from 50. floor of my building, infront of tv cameras, i swear, and i am ready to put some REAL money on this! Like Carl Moreland did in the past and no one of you - frauds, havent "balls" to accept that. So on Carl's $25.000 i will add another $25.000, which makes $50.000 only from me. I'll keep my identity hidden, but i will process money and withesses through my advocates in USA.
So once for all, you small, miserable, southamerican man; stop spreading NONSENCES here any more. GIVE PROOFS OR SHUT UP WITH STUPID NONSENCES AND OBVIOUS LIES!
3.000e.!?!?!? Are you that lunatic? What you showed on your photos is worth bairly...3-5 euros, no more!
Lies and nonsences again and again.
What administrator has to say here?
Ha Carl?
This is what you called democratic ha?
Me to be banned and frauds and liars (same old ) to come here and post **** gain and again.
So ok...do that again Carl. Let me be banned again.
I still do not have neither one reason to be here any more. Not because those are here and posting trash and garbadge but because YOU mr.aDMINISTRATOR are very silent upon this?
You are very silent and constanlty absent?
You let most revuslioned lies to be posted here by same old frauds and liars, month by month...post by post...
Buuuuaaaaakkkk on all this!!!
Real proof how this guy is out of focus, again!!! Lose the compass...

You can't spend neither one day without me?
Whenever i decide to leave this, you show and "ask" me to come back here!?

Things here could not be much simplier Esteban; you only need to show some real stuff here, at least for once!
Every time other here start asking you a proofs, you disapear for a while and come back with brand new photos and brand new unprovable claims.
You escaped all queastions from other thread and came here with new device...3000e!
Ok, proove that it is worth of 3000e or....shut the f.u.c.k. UP! Once for all!
You just keep asking for my attention, i will be here for you constantly!

Just because Max is here, interested in this subject and very imoprtant that Morgan is also here with his claims - but very modest and calm claims, i decided to pay full attention on this schematic. I will analyze it. And i will try to form some sort of objective opinion on this. I wil be fair. I will admit if turns that it is workable as Morgan said.For the first time here i will not reject this idea as nonsence. But just because Morgans attitude here looks more sane and descent than others lrl'sts in the past.
Morgan give me few days and i will come here with opinion.
You could help here more if can provide at least some closer details on coils used here.
Regards

Hi Robert,
There is several persons interested in this subject.And coils are still the big question.
But the trick is what is to be detected.That is the question...

Fred.

Agree. But to know that, we must first analyze it properly. First things comes first.
Ok, diodes here bugging me a lot! Are you sure on their right orientation?
It is quite obvious why gremanium diodes must be used here. I would suggest AA119 here.
But their present orientation are confusing me!
Are you sure on this?

Ok skim look on this tells me that coils are fully resonant.Must be tuned critically.
There are rx and tx parts directly coupled. I have been seen something simillar in the past
only cant remember exactly where?
I guess this part (middle of schematic) is taken from some old md bfo project.Probably from those in patents database.
Should search trough databases to find exact match. Designer, here used simpliest possible bfo approach and
added sort of direct receiver (down part of schematic).
So it seems receiver is able to pick only eventuall differences in balance occured in metal vicinity.
I guess this will somehow "detect" some metal. Logically metal in coil vicinity will slitly disturb
balance. But i still do not see great benefits from this?
This will indeed react only at very short distances. Maybe 10-20cm on larger metal items...maybe.
Why added direct receiver while classic bfo md has already possibility to indicate balance disturbances?
I dont have a clue? I guess designer experimented just to see results, without much of idea.
Also, we have here two "received" signals - two informations (very rough).
The one from RX coil and the one from ferrite rod direct receiver.
Ok principle here is almost understandable. But what benefits from this one?
I dont see quite benefits at all.
I'll repeat, this will "react" only at very short distances.
It is to early to make some conclusions.These were my preliminary observations. I could be wrong.
So for now i will stop saying anything and return to analyze.
I am not bugging myself here with distances. I am sure those are very low. Just want to examine
this design full and decide if it is usefull or not.
So far it looks just as pretty rough and obsolete approach,taken from some old patent from early XX century.
This will continue...

Nice work ! keep going!

Yes you are right about diodes.
Anyway this ferrite circuit seems to be disconnected when the detector is in normal operation.but there is many doubts about the switch connection.

Fred.

Hi Roberts,
Excellent observations! Please continue. It will be interesting to hear your ideas about the two separate detection curcuits.

"It will be interesting to hear your ideas about the two separate detection curcuits.."

It is quite question. I guess only original designer knows right answer.
My presumption would be that second reciver - direct receiver with ferrite rod, actually have unusuall role here. If those coils are fully resonant, than weak signals would not be enough to disturb balance. Therefore some extra "disturbing factor" must be added in overall circuitry - i guess direct receiver is there cose of that..But than again, if i am right, why using fully resonant coils???

There is two coils on two ferrites cores in the same axis separated by a "crititically adjusted" gap.I am not sure if both coils are wound on the same core or not.

Oh yes!? I havent spotted that!?
But if was like that, still i dont see reason for making gap between "active" and "passive" core? Making a gap will cut out induction which supposed to flow through cores. Cores are generally used to improve induction, to boost it not to stop it.
That particular stage is actually a big question. The rest of schematic is pretty clear.
I still think that stage was added in existed design by experiment.
When experimenting, discovering new things, man can easilly do some things pretty wild, without following previosuly planed routes.
It is so hard for me to make guesses here without having device and measure
some values in vivo.
According to what i do know, direct receiver will receive raw signal produced in its vicinity. In this case, eventual distant signal will be absolute masked by field produced in coils, if coils and ferite rod are close.
I still dont have a clue how coils and rod are oriented?
I remeber once Ivconic and me argued about ULF and its eventual use in lrl.
I can give a hint here (once gave to Ivconic) how to make very efficient ULF antenna, in manner to suggest you to replace existing ferrite rod antena with new one and than see changes;
well...
take 12 ordinary ferrite rods, 100mm x 8-10mm. Glue those togather and make one fat rod, 20cm long and 6x1 rod fat.
Wound 600 windings 0.2mm wire, isolate it very good, wound 450 over those 600 and isolate again. You will have 4 ends. End of 600 and start of 450 solder togather and you will have 3 wires than. Use it instead this one and see changes.

Hi Robert,
All info about ferrite is in the "...492 feet" thread.
Anyway by adjusting the gap you can slightly change permeablility, thus
frequency.Maybe you could get them in antiphase and obtain a perfect null?

Robert, i cannot understand you: in precedent messages you told us making an antenna for VLF would take thousands of meters of wire, now you give the recipe to make one , and more, a good one ,small enough for our purpose ???
Regards,
Fred.
