THE FERRITE TREASURE SENSOR

[maimoune]

hi Esteban
Very intersted
good luck

No at high distance, just 5 meters. Better for big items as treasure.

Now I replace magnetic speaker by piezo, this not disturb as speaker based on coil and magnet. Also consumption is lowest.

Now, I'll replace the audio amp of radio by circuit based on NE5534 or similar. This is just for to try ferrite.

So, you will connect the ferrite directly to the 5534 ?????
Or you will use the first preamlifier with transistors??

If I got this you can pick up ring a 5 meters.
If this is so it can pick up Carl's 10oz gold bar.
THAT IS $25,000 YOU CAN GET.

Finish and works great! Treasure can't scape of it! Is easy to mount in a plate (in this case, fiber glass), all are at hand. Radio is not use here, just amplificative stages.

Hey Esteban what country do you live in .. let me think it is the tropical region somewhere

I prefer 2 transistor pre connected to NE5534 or similar IC.

Since 3 days we have 44-45 ºC at sun, in the street, here in Paraguay, South America.

Good. For me is better to use a preampl all with transistors and in dc coupling. It has better slew rate !!! A good pre is the audio prelude from Elektor

hello Esteban...

good job
I see your near to build an perfecte LRL

I would be the first to buy your devices

Gracias hermano, estamos en conracto.

No me olvido, solo que quiero también terminar cosas que empecé.

The prelude is the sintetizer or what? I remember it...

Hi Esteban
Not synthesizer, prelude ,name of amplifier article ,published
By elector magazine .also at far past.
Best regards.

This is the Prelude, +15/0/-15V

the serious questions

This is the Prelude, +15/0/-15V

Hi Esteban,
I read some older posts in this thread and seems you made a double ferrite antenna with a coil over one half, shield and cable... spacing 5mm.

OK, let me think you are talking about some VLF receiver , say some tens kilohertz, and remember me something already seen somewhere.

But what I do not understand is wich kind of signal you're looking for: 3 questions cover the topic I think at 100%.

Does the buried gold emits RF waves ?
Or the buried gold absorb some outside generated RF waves ?
Or the buried gold enhance/focalize some outside generated RF waves ?

If your device works, one of the above questions you must answer with "yes".

Otherwise I see no way that the device could work by means of being a pure RF / VLF receiver, no matter of "how" that action is performed.

Kind regards,
Max
