Real clone Alonso-PD

[Bill512]

the Alonso PD locate a gold sovering 8gr in air test 30 cm


A copper coin with similar diameter, is detectable from Alonso PD and from what distance?

[Morgan]

PD is made with metal detector, mixed with electromagnetic/electrostatic passive receiver,thats the circuit who play has LRL in buried objects.

Good day

here is the measurement of double 45 Turn coil of receiver in alonso-andreas PD.
please notice that the value is approx but within the range
you must position this coil on omega TX coil and nullify the received signal using oscilloscope.
however, it's function is disputable. is it necessary? does it have a role in remote detection? or it is just for IB detection part? can i omit it? ( seems possible)
anyway, here is the approx value.

Hi to All , Does here Alonso Passive Receive Coil is 2x45 Tour in same Way , and in Total will be 90 tours ? OR
45 tours to one Way , other 45 tour is in Reverse Way ?

[folharin]

you are all wrong on the laps

you are all wrong on the laps

Ok , What is Correct for this Laps ?

Good day
66 KHZ receiver or transmitter?
if you notice to values given and written on the schema, by calculation other frequencies
will appear. practically as i measured by oscilloscope, not much difference in calculation
and in performance.
something is missing in alonso-andreas PD. there must be an "extra factor" which has crucial
influence that PD need it to work and detect even fresh gold under ground.

Mr.aft_72005
Thank you for admiration. Thank you
About instability in Alonso-andreas PD, I disagree with you. In my experience, it is stable.
As picture below, I made transmitter and ferrite rod receiver in blocks and separately.
Despite andreas that said transmitter is powerful, I say no.it is not powerful also it seems
Does not have influence on task or to say it does not have role in target detection.
Anyway, it is discussable.

good day

here are a few pictures that shows 3.5 cm receiver coil
it works just in IB detection section and i think it can be omitted. also its receiver part can be ignored.

i think,not necessary to have weak normal metal detector here.

obviously,for many, it is very easy to make this coil but perhaps for a few is unclear from schema.
just took pictures to illustrate it. hope to be useful.

important: please notice that for adjusting this coil (receiver) on omega coil (transmitter),
you need oscilloscope.

good day
as you know, alonso-andreas PD with such small coil and using low power, obviously
is a weak IB metal detector if using as a normal metal detector.

i don't have standard, international coin such as euro coin or US cents
therefore i used a one-gram 21 C gold coin with diameter of 1 cm also a 9 volt standard battery. both as indicator to be at least international

mentioned gold coin from 2 cm at max sensitivity and 9 volt battery from 5 cm to 6 cm
are detectable by alonso-andreas PD as a normal IB metal detector

here are a few pictures

Good day

i measured alonso-andreas PD current consumption for each part individually

despite Mr.andreas said that alonso PD has powerful transmitter, i disagree with him

it is a weak transmitter. and in my opinion, transmitter has a quite a low influence in remote sensing. would like to say, it does almost nothing.

i mentioned before that another factor is playing main role and perhaps it is UHF signals
transmitting by some stations at Greece also at some other countries

it is clear in the picture that the transmitter uses just approx 3 mAh

you can imagine what is the power of 180 Khz relaxation oscillator that uses 18 volts, 3 mAh. also it produces damped-wave, each pulse has 125 micro second length

so the alonso transmitter is weak and not powerful

here are a few pictures.hope to be useful

Hi behnamvp , I see that when is in noulling position some Alonso PD locating Fresh IRON : Ядосан: (for example Your 9V Battery) from small distance , but so not find buried IRON ,
İf we use Filter with signature of metal or electronic filter , so may be will reject Fresh IRON finding ??

[Morgan]

has you know the iron underground stay rusty very quikly, the PDK or the PD locate conductive metals that not rust or create the patina when underground for many years,noble metals...

Dear Morgan , When situation is So this is very Good info for PD that locating only buried
precious Metals (Silver, Gold, Copper, Aluminyum and etc ...) and reject Ferrous metals (iron , nickel and etc... ) , Thanks for your Test infos .

Morgan I make Test with my PD , that it also Can locate Fresh 3 - 5 gram Silver and Gold
alloys from 1 to 2 meter distance (when PD adust is in very critical position) I'm in shocked .

Also with modification not locating Fresh IRON .

Turn the omega upside down or 180 deg.

Passive receiver must catch spark from 1.5v battery at 2-2.5 m. Find correctposition,which is very hard. You need umetric slide mechanism for moving ferrite only 1 axis to catch exactly 1 point with respect to omega.

Thank you for advice. Much appreciation for trying to help.
Well, many years ago, I had some experiment in making omega-coil
First made one for magnum metal detector ( andy flind)
Then by modification, used it for chrome-2 metal detector
Again by modification, used it for quasar-arm metal detector
Anyway. Technically I do not see difference between straight or upside-down placement
Of omega-coil. Technically there is no reason to turn coil 180 degree or move the ferrite above the coil
In my opinion, no difference in function. At least I cannot find technical reason
About your advice to tune ferrite to 120 kHz and spark test, I disagree with you
I googled and found out that frequency of signal which produced by spark depends to wire and connection length of spark-making circuit. I mean antenna.
So, your 1.5-volt battery spark will produce frequency that obviously is different than others
But according to Wikipedia, by estimation, almost 1.5-volt battery test may produce frequency
Between 50 kHz to 150 kHz. Depends on a few factors.
As I measured ferrite coil value regarding to capacitor shown on schema, it can receive 70 to 80 kHz
All can tune ferrite to receive 1.5 volt-spark. Not hard. Just by changing capacitor and moving coil on rod
But there must be a source or good reason to consider a specific frequency and I could not find
I suspect to beat frequency. When passive-receiver has low-band pass filter which does not allow
Frequency above 15 Hz (practically 18 to 20 Hz) to pass and when you and mr.andreas say mechanical
Micro-movement adjustment, then I suspect to beat frequency.
It should be something between 50 to 200 kHz.
I must study more.

Hello behnamvp
120KHz is correct freq.for Alonso PD.

If you havent seen it doesnt matter its no exist difference. There exist a big difference in near field configuration. In addition of magnetic component of Tx from the ferrite passive receiver there are involved complex configuration of superpimposed Mag. and Elec. fields.

Dont look at Wiki as releable source of info. Its MSM controlled internet media. They write what they want.

Spark gap transmitter is a Tesla discovery. Its HV device where many factors were involved in one short time frame.

1.5V battery is low power, low voltage sourc of extremelly weak mag.field. Its preliminary test for your build. Real test need to be done at your personal test poligon on a real targets. We have deal with EPR of gold, silver and other metalls.

No move ferrite above the coil but center it at bottom line of turned for 180 deg. omega. Correct distance between omega and ferrite should be found experimentally.

For playing with pulses and lenght of wire as function of waveguide only reliable method is TDR or time domain reflectometry. You need very quality DSO and low capacitance probes aslo HV type for playing with this kind of circuit.

Hi humhum
I waiting see your test movie . 1.5 volt short circuit by 30cm wire long produce small electromagnetic domain by step pulse . also step pulse produce full frequency .
Alonso TX when is on produce big electromagnetic filed there fore omega RX and PCB5 can not catch 1.5 volt very small electromagnetic filed . Alonso or heat kit TX act as big wall against 1.5 volt small electromagnetic field. Also in very good null the maximum 1.5 volt short circuit can detectable from 80 cm .
Then any body said detect from 2.5 meter is only BLA ?..BLA?.. BLA?.only talking !!!!!!!

as we all saw, his PD can detect fresh-gold from remote
also his PD is based on alonso-PD

when talking about alonso-PD, we consider phenomenon but, for fresh-gold target
which is on the ground and detectable from far, there is no phenomenon
how do you explain it?

Hi
The electrical discharge from the battery when taping its two poles with a wire, during transition times, emits a really high range of frequencies starting from low KHz up to MHz. For each of the frequencies a hell lot of harmonics also. The test by using the 1.5V battery is valid.:)

Why Spark ? Because wave light is in very high position .

I'm making Alonso pd.
Who approves the image I am sending?
Did they open the ferrite and find out this information or is it just based on speculation?
Or was it based on a specific measurement?

Is the ferrite information in this picture correct?
How is the number of wire turns counted? Was it a guess or did they open the ferrite?

Hi , geo
Please send me the information of PD Alonso manufactur . this is my email mbabakhan50@gmail.com

:lol::lol::lol:
So many people wants to construct the Alonso's PD, but it is not the best lrl.
It is possible to construct one lrl much more simple than Alonso's, more sensitive, more stable and more easy to adjust it. Where is the problem then???? problem is that so many years every electronic or hobbyist reads everything about Alonso's pistol but nothing for other solutions or conditions that must have a lrl.
And nobody (except only few members) are able to construct this lrl because they don't know every secret about it. They knows only what the owner decided to show ....:lol:

More is coming FG80.... for those whom is interesting ! :lol::lol::lol:

You have right Geo! :)

I tried two schemes with problems, it is very difficult to receive signal.change is required.

Do the change. Boost amplification withouth self oscillation. :)

Hi Geo
Make new photo with lrl. Nowdays. :)

[Geo]

I went for T.H 3 days ago but forgot to take some photos. Next time :lol:

With ferrite "out" of coil is more easy to null the signal of passive receiver. But original Alonso;s PD is different.
What is the difference?

[Geo]

Inside the circle of coil is vedry very difficult to null the signal. If u have n't a very good null then u have saturation on receiver.... This is the big problem.

Are you talking about zeroing the Tx signal relative to the Rx coils of the metal detector?

[Geo]

No, zeroing the Rx signal of passive receiver that becoming from Tx .

Got it! Thanks Geo. It turns out that with such a system in a passive receiver you need to put transistors with h21 with a very high gain. In the Franco Italy scheme, it is recommended to put h21 not lower than h21-500. With what minimum gain do you use in the passive receiver Alonso or when using a stimulator, it is enough not lower than h21-500.
