Correction on PCB 3

Hi Morgan,
On PCB3 , lower left corner, i need to know transistors
numbers,and the component in // with R11.

Fred.

Circuit #5

Here's circuit #5 - the one that connects to the ferrites.

Morgan - Please can you double-check the component values, and in particular the component names. Your original diagram is difficult to read, and therefore some of the names (e.g. C3, C11, etc.) may be swapped over.

The RED and BLACK wires are most likely the power supply lines, but where does YELLOW go to?
Also, does anyone have any ideas about the correct connections for the ferrite coils? Morgan - if you can shed any light on this question, that would be great.

Better view PCB 1,2,3.

Hello
The circuit 5,yellow wire connect with bar 2c.
The cicuit 5, black´D` wire connect with bar 2G.
The circuit 5,red wire connect with switch on-off,sensitivity.

Corrected!

Hi Qiaozhi,
I missed your post.
This looks for sure like a simple DC receiver.So the gap could be making the frequency tunning, but as it is not a HV generator, i dont know if we can believe the gap story.

Fred.

Fortunly,Esteban say will have this Pistoldetektor schematic very soon

and now ????/

Hi Morgan....Max.....Qiaozi.
Thanks, very good work. Congratulation
But we need and the rest.......... The head.
What is inside the head (mayby 2 coils..... how many turns??? )
How many turns are on the ferrite???
Without the head we can't do anything.
Regards

[michael]

Yes, Really especial thanks to Morgan, Max, Qiaozhi and Fred.
our eyes is on your hands and efforts. god bless you.
Geo is right, Morgan, man, how about the search-head?
how about the ferrite turns?
please fellows, gather all these data in summarized workable type schematic.
I think if this works well, will become a memento for this forum or at least
in LRL subject.
it will remember one team; Esteban, Morgan, Max, Qiaozhi and Fred.
BTW; where is Ivconic, this great EE man? why isn't desired to interfere here?
I never forget his golden alterations in Zahori. when every time I and my team partners hear Zahori name, remembers us Esteban & Ivconic.

?

? This supposed to work??? This supposed to locate gold and stuff at long ranges??? Ha,ha,ha,ha!
This will NEVER locate nothing but various interferences! Trust me.
Not only that it is absolute bogus device, but i never saw such untidy hand made in my life! Horror! Like 8 year old kid played with it.
People!People! Please return some common sences! Once for all! Those "toys" and simillar BOGUS device WILL NEVER WORK! You only wasting your time!
What a funny place to be!!!? This forum!!! Bravo Carl!!

Hi,
you are right being skeptic, I'm too... but Morgan is doing a good work with reverse engineering of device and also he reported detection of aluminium can (not just gold) that would be interesting to investigate.

Also, if this device is truly an Alonso's design I think all here have some curiosity about...cause of a number of threads reporting about him... and then circuit is really simple... can be replicated on one single PCB, stuff is easy apart some few resistors with higher precision required... but then I think anyone could mount one just using some components from e.g. old radio and see if it works or not.

It's waste of time !? Probably yes... who knows ?

And if it isn't so ? What if it can really detect some coke can e.g. at 1-2 meters away or more ? Then, I think could be really interesting stuff, at least for me.

In any case it's just another electronic project to have some fun with in snowy/rainy days here... bad weather requires some new project !

The difference between this and other cases is that we can reverse engineer it with Morgan's informations and study circuit and guess principle of operation , if any. Interesting I think if at the end we'll discover there's something in the background that need further investigations.

I think we have to leave out prejudices this time, and, as with zahori circuits, test it to know if it works and how... and what can really do:

- can it find just rf noise and sparks ?
- can it detect metals in some way ? if so, at which distance ? limitations ? etc

Do you understand my point of view ? I've already considered that could be a total waste of time... but don't worry about that at now... cause have some spare these days.

Kind regards,
Max

Corrected!

Hi Fred,
very nice work... now we know detectoman was right about this PCB. It's audio section... so have nothing to do with transmitter part.

Kind regards,
Max

Hi Roberts,

The process we are going through is called "due diligence!.
At the moment we cannot rule out this device as BOGUS, unless we test it ourselves. For me, it's more of a interesting reverse-engineering exercise. No doubt this device does something - interference locator? - but we need to check this ourselves. Even at this stage we can see that we've been fed some misleading information. For example - where is this 7KV generator? Circuit #5 appears to be some sort of DC receiver. And where is the IR circuit? So far it's starting to look like a more sophisticated version of the Gold Gun.

You should be behind us in this exercise. This project is the closest we have ever come to "understanding" these LRL claims. Although, to be fair, this is claimed to be a medium-range device.
Don't forget - we're also skeptics!

Hi,
Ok... this seems really clear too.

It's threshold detector and led driver part as I guessed.

So if color is white we know now that it's 19K... then I think that resistor is that way (precision and low ppm/°K coeff) cause have to mantain threshold level at a knowing setting (turn) of trimpot (maybe to ease tuning of the circuit).

Also I strongly think that the low temp. coeff. is required to avoid thermal variations of threshold level (so have sense to me).

PS: from what I see it's kind of low battery alarm.

Kind regards,
Max
