Simple but brilliant LRL

[Infamy]

Hi infamy

I dont understand you. Are you PRO or CONS LRL?

Short answer, you have a problem if that is a serious question.

Those that pedal LRL should be fitted with concrete boots and dumped in the gulf of Mexico. Alternatively they could be ramped into that leaking oil pipe out there and help to save what little natural environment there is in the USA.

Hi.
Outside of my Lab i have a refrigerator.
When the "motor-compresor" works, i locate the wire from 3m far. If it don't work i locate it from 20...30 cm. This is electromagnetic field and not electrostatic. As antenna i use a round coil 20cm diameter.

Highvoltage AC creates a very fast changing electrostatic field so we can detect those power lines from a far distance, but usually static means stable and the term is used for highvoltage DC current fields.

Yesterday I made a test outside - a small and light plastic-bag could be detected with the 20cm plate at around 30-50cm distance.

Geo, please can you put some ca. 30 to 40cm light plastic bag outside somewhere in the grass (without specially charging it before by rubbing somewhere!) and test from what distance you can detect it?

Because first we have to find out if the electrostatic is useable as LRL at all and how sensitive our detector has to be. Perhaps we also have to use much larger or better antennas!

ANTENNA

This is a little off the hook ,but it may be what is needed.
If you cut a spiral into a flat sheet of plastic, you can stretch it into a cone shape. The material will bend to form a type of parabolic concentrator. This shape has been used to make solar collectors, directional antennas for both transmitting and receiving signals. The further the stretch the more concentrated and the narrower the area it can scan. May be cool to try an adjustable one to get it tuned to the application. LT

I will try it today or tomorrow.
With who version of your detector you locate the static of the bug??? with the 3130 or with fet???
I have some coins buried 20years ago. If my electrostatic detector will not detect the bug then i will construct your detector and i will try it at the place with the coins.

@ fenixdigger
thx for the good idea. It is just the question how many antennas we have to incorporate into the final one detector. We could use some parabolic reflector as electrostatic antenna and the coils or ferrites in front are for the metal.



@ Geo
I have the FET version - it has a better audio-signal throughput. btw. that bag was from the greek restaurant, and it is very lightweight.

Yesterday I built the antenna you can see below with a size around 40cm, but it has only around 30% gain concerning the distance compared with the 20cm diameter one.

I think the easiest and most lightweight solution would be simply to stick some sheets of alu-foil onto a stable cardboard that has a size of ca. 1m. Connecting this in my case with a cinch (RCA) plug I would have the best portable and even foldable solution (as long as it isn't windy outside! )

btw. The very lightweigh alu-pipe-circle has around the same gain as the 38x22cm sat-receiver case-cover.

It detects the 1,5m long 220v electricity cable (2 wires unshielded) of a hanging lamp from ca. 1meter. If I switch on the variable capacitor and turn it to fully 180 pF I can reduce the distance to just 15cm (as it would be without any antenna).

But yet it's more important getting better sensitivity.

I've seen mylar glued to plastic with spray adhesive after the spiral was cut for solar. the transmit /receive ones were alum. sheet.

What if you wrapped copper wire around a cone, then wrap the wire with something w/ adhesive to hold it in place, and then put it inside the cone?

That would seem to restrict the input to a narrow area but still give a lot of surface to receive signals just like the spiral. LT

Very nice construction Funfinder indeed. Like small Large Hadron Collider.

Try rotating to 13.7 degree nach Ost.

Funfinder,
You are going thru what I researched many years ago. The thing to have the detector "look" for are ions. Ions have a specific electromagnetic radiation pattern when they discharge. If the LRL circuitry is set up to look for that pattern then you will have something.

Electrostatic by itself is a waste of time. I stated this in a previous note herein.

Isn't this back to OKM's units? I hear some people swear by them and others swear at them. After all the non treasure I have dug (a mountain) compared to the treasure (a small bucket) due to misfires with mfds and the associated variables, It makes sense to me that the ions would the way to go.
Very good point Goldfinder.

Wasting time can be a good teacher of deeper truths and wisdom for some people.
Besides, this antenna can be used as a toroid top-load on a Tesla coil if it fails to work for locating treasure.

Many paths to top but view from top is same!

Yesterday i tried my electrostatic lrl to detect the static of a plastic bug WITHOUT results. After it i went to the place where i have mercury burried and i tried the lrl again. I took some random signals near to the mercury but i am not sure if they are from it. One of the next days i will try again with other lrls. Also i will try to make the detector of funfinder so to see if it detects the mercury or some coins burried before 20 years.

Hi Funfinder.
Can you please post the frequencie of this divice.
May be i can help with my expirence on modeling and constructing antennas.

@nelson
The frequency depends on the Hertz of the nearby higher voltage AC-current and is audible in the whole spectrum for human ears.

If there is no strong AC voltage field, it has only switch on or off.

To make this device much more sensitive I'll try to find a way to inject some threshold power into the antenna (FET Gate) so it just would take a very small plus of energy to make the FET switch on (or even off, if kept in balance between on or off).


@ goldfinder
Yes, the ion patterns will be the next big project, but still I think even with electrostatic you can detect metallic distortions in the EM-field because I tested this already with that silver ring. In this case was the metal between strong current field and static-detector; but the natural field has some special current - so the detection is more difficult, and especially variable by the ground conditions.

[Funfinder]

There should be a way to calculate the detectable electrostatic distance:

variables:
s=sensitivity of JFET or MOSFET integrated circuit
e=size of electrostatic detectors antenna
c=transmitter object size (lenght of power line etc.)
v=voltage
a=ampere
h=humidity in air
i=irritaton (ground, sun, ionosphere etc.)
b=blockades (mineralized stones, trees, soil etc.)
