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]

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

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

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

[Zicos]

thank you very much.

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.

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