Action of the Earth in solenoids

[hung]

Esteban, if you don't post complete schematics how can I build an LRL for myself? I said I wanted to prove whether I ret results. I know I appear a sceptic in other posts, but I have been reading about these things and I, along wit hmany others here, wish to know more yet you won't tell us or give us the tools to learn.

If you are a 'real' electronics engineer with some serious research attitude, then Esteban's hints are more than enough for you to start your own thing. In fact I should prevent Esteban of quiting posting even half schematics as there are the risks involved as we have already discussed.

If you happen to fully understand the phenomena one day, then with just a FET , a LED a couple of minor things and some wires you build up a working LRL.

Esteban knows how to protect his own research and he knows as you should, there's no 'lunch for free'.

Risks, would that be that they could be analysed? That was not my intention, to ridicule. Why all this defensiveness all of a sudden when a valid request is being made for help. I am most concerned there is something to hide, yet if these devices truly work, why would you do that?

You give sceptics cause to believe that your motives are more than a desire for your "competitors" not to see your designs, but I worry that there is more going on here than that, and that does not look good.

At every turn I see evasion and for someone who is openminded to the possibilities or LRL's (after doing more research) I find little cooperation here.

I will build my idea and then I will design an LRL based on REAL hard fact truth electronics. When it works, and it WILL, I will come here and show you pictures of my treasures, but I will not tell you how I made it or how it works.

See, I can be that way too. I have not asked for anything special, but I will not give it either even though I may have it to give. I too can deal in falsehood but I prefer not to. If I create a design that works, I will happily give it to those who have helped me in the past, but not those who don't . The ball is in YOUR court.

2) The ground is "ringing" and thus so are the targets.

I found than when a truck (diesel engine) vibrates the soil in zone with "false terain" the target is best detectable. Expect this movement produces another secondary phenomenon.

[Fred]

Looking at the probe I'm thinking of a way to detect anomalies in the surrounding voltage field of possible targets. If you chop the input to the primary at say 59KHz (I think you said that was a Gold frequency) then have a narrow band filter on the secondary, you could monitor the AVERAGE field and look for slight changes.

The more serious schematics i have seen before all rely on this principle.
The problem with averaging a signal and staynig always at the edge of triggering is that you end with a random beeping that your mind can associate to targets....

OMG I'd completely forgotten about Telluric currents!! One further thought, with all the RF and LF signals pumped out by te human race these days, might they not also cause some interaction with a "desired" target? See the Compass Depth Enhancer. Also I have found that searching with a conventional metal detector in a field that has an active electric fence around it, I get a LOT more depth (and ear bashing), but the depth is a DEFINATE 1.5 to 2X normal. I wonder if;
1) The targets are being "precharged" in some way.
2) The ground is "ringing" and thus so are the targets.

I think the signals to be detected are variable (AC),so they must come from external source.
You electric fence observation is very interesting and should be better documented,to avoid "mind effects" and for example to see how long after turning up the fence and after turning it off the effect remains.

If you are a 'real' electronics engineer with some serious research attitude, then Esteban's hints are more than enough for you to start your own thing. In fact I should prevent Esteban of quiting posting even half schematics as there are the risks involved as we have already discussed.

-If it is so simple why not to post it anyway ?
-Why Esteban must obey you so quickly ? Are you is boss or superior to him ?

[Esteban]

Ooops, what patents?
Ignoring the un-patentable designs that were taken from other designers, and cannot be patented, can you think of any reason why nobody who has a working LRL will post a schematic for a simple LRL that finds stuff like aluminum at 10 feet distance?

A simple LRL that only finds aluminum will not start a rush of Chinese manufacturers mass producing the LRL. But is will serve as a good tool to test to see if it is detecting currents in the ground, or ions or some other geo-signal from the buried target.

Best wishes,

I found a site with many aluminium cans (at first moment I think that are aluminium cans and unbury one as a sample). So, I surrounding the area from all positions and don't was detected this aluminium cans. Previously at 5 meters of this "cemetery" of aluminium cans (aluminium cans are not corroded. OK? Maybe corroded is other case...) I detect a site and found a bronze coin and Nintendo token (is correct here token?) one on other one. Don't know wich alloys is this token, but the both was detectable exceptionally very well at 3 meters and continue over the targets. Also don't know if the mix of this 2 kind of metals produces a "variant case" as Volta battery because a 1797 or 1798 Spanish silver coin don't was detectable very well. The conjunction of this both metal was better detectable. Any theory?

PS: I found many detectors in old magazine maybe never was patented but some years later other persons appears as the "inventors", one of such devices called impulse detector wich works as pulse induction...
To patent any invention is expensive...

That's funny!

I was just going to ask the same question.

[Esteban]

If you chop the input to the primary at say 59KHz (I think you said that was a Gold frequency) then have a narrow band filter on the secondary, you could monitor the AVERAGE field and look for slight changes. This may work as a detection method, but it is NOT psuedo science, this is hard physical. An Electronics Engineer would be able ot make such a device in a few hours.

First time I use 300 Khz with other coil, no tune capacitor used here, but frequency was 300 Khz. At this frequency I found cigarette paper and other junk. But at 59.5 Khz don't occurs this, and can't asure that this is the gold frequency, but at this frequency other "bad" metals are rejected. Maybe because at 300 Khz more great variation of frequency is noticeable, but at 59.5 Khz the variation is low at presence of these "bad" metals, so detection doesn't occurs.

Hello Esteban

its possible adapt to Pistoldetectors some variable knob to change for diferent frequencies ???,i mean something who change the freq. from ferrite.

And this proves a point, homemade LRLs are better than the name brands for sale , which shouldn't be too hard to do.
Hung even mentioned he doesn't use the Ranger anymore because he made his own.
Now the whole future of LRLs are in the hands of homemade builders that won't divulge .
Ok, I can see not giving away all your work for nothing, make your LRLs, put the electronics in dark epoxy and sell some .

Not to worry, Steve. If there was anything at all to the technology(?), and it actually worked, it wouldn't just be known in remote corners of this world by one or two that post on this forum. Neither would it have to be hidden in black epoxy. I like all your "laughing faces", because it shows that you think the same way I do.

Yes... Sometimes in the remote corners of this world you can found some things... explorers know this since remote times and maybe remote sensing (in this case based on electronics) can be one...

You can start with the magnetic field detector by Andy Flind published on Everyday... magazine. No transformer is used here, of course.

Here the Andy's project inside my fiberglass pistol.

I will try to find this schematic in internet.
Thanks for this information.

SWEET. Andy the Genius strikes again!

Andy was a very good friend of mine and as you know, sadly passed away a few years back .

It's good to see his genius still producing the goods

Yes, Andy was a great man...

Morgan, you can't found in internet, this was published on Everday with Practical Electronics magazine in the 80s.

Is very simple: you connect the loop-core system I post here instead the transformer in the Andy's schematic. The output you connect to the comparator/timer/tone generator I post here. You put a potentiometer instead the audio preset in Andy's schematic as sensibility control. The bargraph preset you adjust when first led of. Better if this circut is in metalic case, loop must be outside.

For rights of the publishers, I can't post the Andy's schematic.
