Andy Flind MFD.

[Zicos]

Also, what are the capacitor prices???

[Zicos]

which one do you recommend????

[Pahom]

good evening.without phenomenon i can't test if something works or not. that's why i asked.
For this circuit, it is considered good operation of the device if the device catches an impulse from a quartz clock operating at 1.5 volts. For example, a wall clock. The farther the watch is from the device, the better the sensitivity.

[Zicos]

thank you Pahom.

[Zicos]

the 5k potentiometer, which is placed on the preamplifier??

[Zicos]

I understood where it is placed..

[Zicos]

Hello. the watch does not catch it. only my hand,, and that not always. Watch the video...

[Zicos]

the coil consists of 27 turns, 0.30mm coil wire. 17 cm. diameter. in parallel with a 22nf capacitor .... the coil is 0.19mH.

[Zicos]

i think it will be a long time before it becomes functional for treasure research. Hahaha.

[Pahom]

right . This is now your search for the frequency you need and work with the teacher. You need to achieve a good sense of the clock's impulse. or wait for the phenomenon on your training ground!

[Zicos]

is there proof, that when the clock strikes, the phenomenon will also catch?????

[Zicos]

can anyone confirm this?

[Zicos]

when I rub my hands the buzzer rings from a distance of 0.50 meters. is this positive?

[Zicos]

I removed the cardboard box I had on the coil and it works better now.

[Zicos]

the machine is catching it on the watch now..... short distance but catching it.

[Zicos]

now he wants a good box and he's ready for phenomenon hunting.. hahaha.

[Geo]

Congratulations. it is a good project

[Geo]

No. It is more positive to catch the watch and no the hands....
Good luck with "βραχιολι" :lol::lol:

[Zicos]

thank you very much.

[erfan]

I know that testing these devices with the hand of a watch or a battery spark or a lighter spark or a mobile phone in contact mode or ....... does not mean a useful function for finding buried precious metals.
Maybe you are trying to perform these tests from further distances with changes in the circuit, but keep in mind that these tests do not mean receiving the effect of metal metals from farther distances, and in some cases it is even completely the opposite and not useful.
You have to look at the matter realistically. There is no simulation.
The path to progress is only in building, taking steps and testing in the real environment, that is, only testing in the real environment and measuring the results.

[Geo]

These tests are good in case that u want a to fint better sensitivity without the using of special instruments :cool:

[Zicos]

hello fellow hunters. I would like the opinion of those of you who have tried Andy flind circuit 1 out hunting. are the readings taken from the target continuous or with a break in the signal for some seconds like an alarm??

[Zicos]

the signal i am getting what signal is it? magnetic, electric? Or.....????

[Zicos]

the circuit I use is a coil, preamplifier and Andy Flind's circuit 1 with its conversions.

[Zicos]

anyone who doesn't want to answer publicly should send me a private message. Thanks.

[Zicos]

Happy new year with health to everyone.

magnetic....

If we use p.m for answers then who is the rοle of the forum and why Carl to pay for it ???:(

[Geo]

Happy new year with health to everyone.

The best wishes and by me!!!:)

[Zicos]

thank you very much for the replies Mr. Geo. The reason I say private message is because I see in the forum posts most of you ask for an email to give some information. I have no problem being answered publicly or writing my questions and experiences from my tests publicly. many wishes for everyone.

with my Andy flind in the woods I pass a signal from 25 meters away. the signal starts with three leds lighting up and as I get closer to the source of the signal all 10 leds light up. the point is 4*4 meters where all the LEDs light up. but the signal lasts for 5 seconds and then it goes away and after some seconds it gets it again and again the same thing. what am i getting???? In a test drive I went to, it doesn't catch anything. only in the forest.

[Zicos]

I've dug a lot and pulled out a lot of scraps of copper and aluminum and iron but it still rings. the same fragments are everywhere in the area of 400 acres, but I pass the signal only there, nowhere else.

It sheems to me as selfoscilations, not as signal

[Zicos]

if we assume it's selfoscillation, when I'm 25 meters away, the 3 LEDs light up like an alarm for 5 seconds, maybe 3 seconds, and then it disappears for a few seconds and comes back on again. when I get closer to 15 meters, 5 or 6 LEDs light up again in the same way. and when I reach the point 0 meters which is a distance of 4*4 meters all 10 LEDs light up but again in the same way. I am very confused.

hallo all ...after 6 years ...:D

it's NOT selfoscillation

EXCACTLY this signal i see it with the phototransistors before a year (i do not remember what is the name of circuit) .

1. every 2 second without interupt .... sine wave (vov .. vov .. vov)
2. Barometric pressure was very low
3. low black clouds before big storm
4. impressed me and I sat and watched it for an hour while drinking my coffee.
5. I looked up the history of the place and it really is strong and goes back 130 years.
6. It was in a residential area and there was no electrical consumption
7. I detected it from 40-50 meters and centered it on a 1x1m area
8. I never met him again.:D

WHAT WAS THAT I SAW?

[HaFar2010]

Hello
Dear All
can you introduce a good beep generator for Andy so that it can produce a beep if the first led is only turned on?

[Zicos]

hi HaFar 2010. can you use andy flind's tone generator with headphone jack 6.35 in my tests when i approach the clock first i hear the beat on the headphones and it has to get a little closer to the clock for the light to come on. while with Alonso's sound generator it beeps when I bring the clock closer to the coil compared to Andy flind's generator.

[Pahom]

As far as I remember, Alonso's tone generator is connected to the tone generator on the 4016. Headphones were not recommended for use .

[Zicos]

Hello pahom. In my Andy flind version I use the circuit with the 4016 and instead of a speaker I use headphones. In the same circuit I also have Alonso's sound generator with a switch and it takes the signal from pin 6 of the 3130 through a 100 nf capacitor. the R16 I use 180 kΩ.

Maybe it 's the right thing to do . Although you'd better find out who has achieved success with Andy Flynd's MFD.

[Zicos]

the one who has been successful should mention some advice so that I can try it and I can report in my turn if it works in my tests and in the wild and see what differences it has with my own version. It will definitely be useful.
