Real clone Alonso-PD

[ANDREAS]

Hi Andreas
I wanted start to produce the PCBs and have a question for the transmitter PCB.

In the schematic, is a resistor R7 drawn, but on the PCB is it not available.
Is that right?

Best Regards

Yes is correct. I put out R7, because, sometimes need value R7=10K or R7=6K8. With this tip i can make replace very easy this resistor, before i am sure the standard value R7=8K2
Please wait small time. I need free time and fine weather for video's for publish here more infos
regards

That's not an omega coil. It's an OO coil with the loops having different diameters.

Okay, very good Andreas. Many thanks for your quick reply and tip, I'll be waiting for your new infos.
Wish you all the best

Hi dear what you said???? is not trust please

May i ask what is the purpose of the circuit, (except scaring mosquitoes) ?

The Generator

Andreas, A signal generator can be used with the PD locate a treasure. or Pulse Induction Detector may make stronger the phenomenon that can be detected for PD..

I don't know if alonsoPD need a external signal generator or PI for stimulate a target.
I think don't need.

I did this circuit just to see how it behaves pd with a sign around 68 khz

Hi Friends, Hello Andreas,

I tell you that i did the coil exposed by Andreas but without good results
this detects much less distance than the omega coil I made earlier,

I've been looking a lot of information about how to make an omega coil and reviewing many images and found in my papers a document to Andy Flind where is the way to make a bobin omega compensated for a metal detector and catches my attention because this omega Andy has other features elaborate and I think this could help us develop even on a smaller scale an omega coil but need help from someone here on the forum who can do calculus to make it equal to that of andy but in a smaller size perhaps about 8 or 9 cms. diameter

this is important because the omega coil exposed by Andy I think this well balanced in its measures as should be a real coil omega because maybe this can work well in the Alonso PD.

As you can see #89 ......with perfect calibration all together coils-housing detect one euro ONLY 12CM DISTANCE..
Alonso PD don't work as a real MD detector, but as LRL
If you replace C4 (see #116) with value <10nF, you have more distance detection.
Ofcourse with C4=100pF... 470pF you have best distance detection.
I made this clone with the true values of the components posted here few years ago.
I saw this is real "distance detection" of omega-coils when everything configured correctly. In this case we have a real LRL and a "poor" MD.
You can ask the morgan. He has the original PD, he know well the real distance detection and measurement real frequency tune. If he publish real infos (Rs forum), i don't know, because, i am not member
My opinion... he never publish real infos or he cannot build a real clone (i am sure for this)
If we want a better MD section, ofcourse we can replace with other schematics.
I think later i replace this section

hello guys, put the tx in lrl detection, help for a little most distance range, and most directional precision, too for most centre habilities, but any persons say, the tx near of the metals point, due hig tension oscillations can null the field of electrons around the objetive buried, how a short circuit, then you see all signal dissapared, morgan say the tx help for can be detected in minor size objects

Hi Detectoman, how are you man, tienes toda la razon hacerca de lo que dices y que milagro que te veo aqui, que hay de nuevo hombre ya terminaste tu PD? he visto algunos videos tuyos en you tube de un equipo que hiciste se ve muy curioso pero bien, un saludo

You're right in your said, a miracle for me see you here, what's new man, finish your PD? I've seen some of your videos on you tube of a device that you did, this looks very funny but good

greetingS.

[detectoman]

hello lrlman, regards today i have a medium" range in right function, and other one in succes vies and 4 others in process, sayme what you from, may be we interchange opinions

[detectoman]

ups lrlman: where you from *
