DEMPI Aurora

[Funfinder]

I'm already happy to receive Carl's 25.000 bucks LRL-challenge money!
But perhaps he can keep it and buy for itself some nice electronic-equipment
so he can built soon his own "Half Long Range Detector".

Because now I have invented a directional antenna method which
is in the range of YOUR knowledge! No, not 110v detectors *laugh*,
besides the real directional HF-pulse-induction which is a little bit
too tricky for you (the best are some radar-engineers for that task)
I will lead you now the way which you can go, too:

Or better not? Ah no matter, lets play a lil bit:

First you have to google for yagi and magnetical antenna!
Before you must not start at all.

Next, you should have an idea how an electron-accelerator works.
https://en.wikipedia.org/wiki/Synchrotron
You get the point already? No? Come on, a bit more creativity!

OK, then you can start but you must be able to built a PI circuit.


More I will tell you next time ...or not... - depends on your reactions.

Who wants to dig a coin at 1 meter depth better have their head examined.
A similar device was used in Havana, Cuba, against American Embassy. They called it a sonic attack, left every one brain damaged.
Don't forget to put on tin foil hat when operating such a device.

> No, not 110v detectors *laugh*


Lets give you a second way of achievement because not everyone ist
interested in this a little bit boring usual PI processing technology:

Yes, you can use "high voltage" for high gain if you are not too stupid
to touch the contacts of bigger electrolyte capacitors with both hands! *laugh*
I guess we have here some skilled persons who can do that.

Don't worry, you don't use the mains which is in America just "weak" 110v anyway.
btw. you can grill your car also with just a 12v or 24v battery if you clean the
contacts with a steel-brush and some contact-improving cleaner!
Its not just the voltage, its als the ampere !!!

You also can hold a lamp with 50kV in your hands to make it shine without
big danger.

OK, thats just for your warning - leave one hand in your pocket as
precaution-measure if you wanna be even more safe.

The idea is pretty simple!
What you need is a camera flashlight.
This is a truly bright idea of me, I know! *laugh*

After plugging the flash off from any power sources and discharging the cap
with a resistor bridge (use one of those big 5W ones, perhaps 1k) and hold
it not with your fingers (hot) you can disconnect the cables from the bulb
and attach them to the coil.

Et voila, you have a real nice high-voltage-EM-pulse!

Catching and processing (comparing) such a real heavy signal is now
the real challenge. This little flashlight electronic shall not grill your
sensitive receiver-circuit.

But I'm sure you as PI profis here *laugh* know some tricks for over
impedance and the circuit has time to regenerate.
This detector will not "fire" all the time PI-pulses but only when
the flash-cap has recharged again - quasi manually.

Now you have method 2 but if I know this "extincted" forum (seen from the amount
of members) correctly, you are not able to make any valuable out of it, anyway.
No motivition, no interests, just a little bit of repair-problems and small-talk here and there.
Compared: You are the same down as the whole Playstation-Scene! *laugh*

Perhaps all the treasures (you did not find so far) made you sick! *laugh*

No enthusiasm, no excitment, no ambition, not being hot for a great project - NADA!

Anyway - take it or leave it, I don't care, because I or better we (those who have
still the same drive and power concerning fantastic improvements like me) will
reach sooner or later our goal of a: Highly directional middle range metal detector!
And seen from the ideas and technical principles - we have it already.

Then you still can play with your 30cm coil toys and scratch on the surface! *laugh*

[Funfinder]

If you wonder what is this? M = coil while = = the staff. *laugh*

The problem with you here and with the whole MD-world, besides those crazy LRL-freaks is:
You can't imagine that directional magnetical antennas are possible and thats why the
possibility of middle range metal detection doesn't exists.

You think that you are bound to some electromagnetical laws but this is wrong or
better said only correct if the soil itself already acts like a thinned "metal-soup".

What you see above is a magentical pulsed array:
The induction of coil 1 amplifies coil 2 and so on.

This works perfect in air but also in medium mineralized soil.
Even with a frequency above 100 MHz.

Compared to this, the usual coil EM field is totally restricted
or only improvable by higher voltage.
PI's with "car batteries" and 1000 volt pulses is the result.

On the other hand - for the normal treasure hunter the usual
technology is already good enough anyway, because he likes
shallow holes (not much digging work) and lightweight MDs.

And frankly spoken: I am happy and satisfied already, too,
with what we have meanwhile.

This whole directional thing is just some new hobby to
reach something nobody reached before so far.
Call it a little challenge.

Or do you think I love nothing more than to dig 2 meter
(6 ft.) deep holes by hand? Result uncertain.... *laugh*

But this makes me feel free: I don't have to find at all
costs a method for true directional treasure-detection
but the motivaton to look for it, feels great.

Good luck, fellows.... Seen from the reactions here so
far I guess I better will exclude you from this project!
Others would pay 1000s of bucks being able to be a part
of it but you know: Anything wich is free is "worthless".
Until someone loses it - like its health or relatives etc.

But since nobody so far has developed reliable working
longer range directional MDs besides magnetometers,
nobody would miss them much.

Which is stupid, because there are regions in this world
so thined out concerning "metal-pollution" and treasures,
that a metal-detector with 5meters range or so would be
the minimum to be searchable at all.

Tundra, steppe, Siberia, many underwater locations but
also woods, roads and fields at regions without a larger
population or towns every 3 kilometers.

Not to mention the depth if there is a huge pile of crap of
destroyed towns rubble and the good stuff is deep below.
The treasures of hill- and other tombs are also far away
from the surface, for sure not within the reach of even
our modern 1 coil detectors.

Ground-Penetration-Radars might find the huge cavities
5 meters below if there are any, but metal, too?
There are many cases where these GPRs showed very
misleading informations, leaded to deep useless holes.

But we will see - or better said: I will see! *laugh*

[Funfinder]

Well, the input here in this topic meanwhile is pretty low but I'm sure its because its
out of your technical competence. Hahaha! Or which one of you here can built a
GPR which - under good conditions - also can reach 10 meters with a 1 meter coil?!

But what you must understand:
Outside in this world there are professional electronic engineers and they don't
care at all what you are thinking, writing, ignoring or tinkering here.
Because they don't even take you serious and wanna make big business.

This with the "I will exclude you from this project" was merely some tip with
the toe in your butt to motiviate you a bit but if I'm finding out that you are
totally incompetent concerning this project, you will exclude yourself anyway.

Hahaha, when I compare the motivation from some here with their
"lets built the TOTEM" - how ridiculous! This was nothing than some
handheld-magnetometer combined with outside "longwave" input
which should bringt the metal to "ring". It was not out of nothing
that in the 2nd edition of the ITMD book it was removed. *laugh*

Now you have the chance to invest your energy and creativity into
something real working but it it seems you are numb. Your loss !!!


Anyway, either you have some knowledge about directional magnetical
antennas or you are wrong in this thread. Best you come from some
ham-radio background so you can understand the basics.


Because what we have to do is to energize the metal directionally and
also receive the radiation of this energized metal by directional antennas!
But I guess that just 5% here even know what a directional antenna really is.
5% from perhaps 20 visitors per day ... And even this person has other interests.

I think we are mainly dig-able target depth detectorists that are happy with detectors like the Equinox 800 except for VID accuracy and discrimination. I personally sold my Equinox as I preferred using my CTX at my beaches. I don’t have any ambitions to dig with a backhoe to get a gold deposit, or whatever. Those that have these ambitions will buy your product if it proves itself but few are likely to build one without seeing it work beforehand.

[Funfinder]

Yeah, most don't like to run around with 1m coils. Too heavy, too
complicated, too much battery drain, missing too many small finds.
All this crap which is understandable but no solution!

Thats why I loved the JeoHunter 2010 in the first place, because
with its high sensitive 44x35 IB coil and non-motion circuit it
was already a pretty good compromise concerning real depth
while still finding a lot of the smaller stuff. 1cm bullet @ 10cm

Another point is the selectivity or distincting inbetween pretty
narrow located objects where a small coil has its advantages.

Seen from the causing and receiving eddy-currents, there exists
many options for middle range detection, even V-H polarized
waves. And the GPR-technology also is improvable.

But this is useless with the missing contribution here, I will
do this on my own -when I have finally enough time - and
afterwards perhaps surprise you like with the vibration-circuit -
which - btw. - also is improvable.
Either by certain dongles so all MD works with them or
different pre-selection- and amplification-stages.

There is an "overloading" error somewhere which makes it
useless for a few MDs. Perhaps this also has to do with
static charges, because this thing is such ultra sensitive.

This Dempi Aurora project is not dangerous for health and first it is about to detect stuff,
not to dig it up. Its also about detecting by a handheld device a 3m away large object
instead of with a 1m coil.

Using a dish as reflector means that the radiation gets blocked from the body by this
dish but its not clear so far if its needed. We can do this also by pulsed coil fields
which then rather would look like some magic-wand if the coils are just 3cm in diameter.

If this crap would be not so unreliable we even could use some "natural" radiation.
But depending on the location even strong AM or SW radio-stations would give
totally different and not reliable results.
