Hi, this works! But with small changes. I have a need to tell you this. A few months ago, I struggled with this (then I didn't know how to read electrical schematics) and I didn't manage to put it together. But now, last night, I made it! It is very functional and useful! But how did I do it? Replace the 2.2uF capacitors with 1uF, also very important, replace the resistor around 47k with 4.7k, instead of connecting the minus to pin 1, connect it to the minus of the capacitor that goes from pin 3. This way, this works just fine. The buzzer buzzes, when you get close to the metal it changes the sound. Use a 9V battery to make it work nicely. I did not use an excessively long wire, if you use a very long one, a few meters, then you will have a stronger effect. It also works with a diameter of 10 cm, but I put 5 cm (I used the same length of wire). I put it through the rod and that's it. I also added an LED, connected in parallel with the buzzer so that I know when it is on, although the buzzer buzzes, for the sake of aesthetics, I like it. Greetings and cheers! I am available for additional questions! Update: Instead of using a resistor, use a potentiometer, I used a 100k. It is very easy and precise to set the diode and the buzzer to react only if the metal is approached. Greeting!
@@shiva.chennai Hi, I honestly haven't tested whether it works with non-ferrous metals so I can't answer that question. It works with aluminum, iron... That's the only thing I've tested.
Thank you dear friend you have made physics and electronics entertaining and tutorial homes will not flourish I wish you the best The search coil indicator L increases and audio frequency gets reduced thanks
David A Loving Sir,notice the video carefully at 3.21sec..The Metal Detector is sounding shrill (not like a Dove). Actually there is a real Dove in the meadow or grassland where this you tuber has gone to verify the work of his metal detector project..☺☺
Hi i wonder that, can i use your circuit's outputs which already drives spekaer for arduino? İ want to make a circuit that is sensing battaries,big ones or small ones....please help and give an idea...thanks..
merhabalar ben bu devreyi bir okul projesi için yapıcam fakat kullanıgınız buzzer mı yoksa hoparlör mü ? buzzer olsa bir direncle baglanmalı sanırım degil
Bonjour je vous demande s'il serait possible de me faire connaître quels sont les composants électronique pour fabriquer un détecteur de métaux à double bobine je vous en remercie
sooo where do you solder the cap's or the resistor? if your gonna show us how to make it then show us... don't just poke some components through cardboard and expect us to know how they are set up.. I mean if we knew that we wouldn't need to watch this eh?....not all of us have ESP...
gu gu ....gu gu....
American Hacker Wut?
American hacker you also watch it ? Woww
Faick ha bhai
Bajar not mach
Finally, a good tutorial for a metal detector

Hello brother. Very nice. Did it work with the non ferrous Metals like copper and gold. Especially gold. Please reply.
@@shiva.chennai Hi, I honestly haven't tested whether it works with non-ferrous metals so I can't answer that question. It works with aluminum, iron... That's the only thing I've tested.
Thanks
I don't understand with change the negative from pin 1 to 3?
The components in his actual circuit are different from his circuit diagram. He uses the 4k7 and 1u0 that you have used.
Thank you dear friend you have made physics and electronics entertaining and tutorial homes will not flourish I wish you the best The search coil indicator L increases and audio frequency gets reduced thanks
I love the idea of using cardboard!
I love your idea... Very good. Be sukses....
Very nice
nice homemade metal detector
Original idea using cartboard 😁👍
could you please explain how to make the circuit connections?
Very useful, especially that I would love to try metal detecting as my hobby... But they are pretty expensive in stores.
Metal detcktiv
this is want to me
Buy used
Hebat bos... Ini benar.. Tutorial nya... Yg laen... Kurang kelas 😍😍😍
How can I increas its detecting range
Does this work??
What happen if you do mutch more turns with the wire?
Dawid Dohnal You get a stronger detector with a longer range of detection.
Gamer Invincible 😂😂😂😂😂😂😂😂😁😁🤣🤣
Use of 10u and 2.2 u capacitors
Hi can I replace that 8ohm speaker with a buzzer instead?
Yes. i also used
What principles behind no sound when no metal present like in professional metal detectors
thanks bro this was awesome!
Hey, you made it sound like a DOVE!!!

now where in the world could I find these exact components?
eBay
Wiring connection for uft confused me. Please make complete diagram that we can make it easy
Exactly
Please tell me about wire gage.this is 38 or 36 ?
NE555 is for oscillation or time delays. In that case, it is for oscillation :)
please add/ link the schematics of this project
Yes please
Ok which copper did u use
What are the materials needed?
merhabalar ben bu devreyi bir okul projesi için yapıcam fakat kullanıgınız buzzer mı yoksa hoparlör mü ? buzzer olsa bir direncle baglanmalı sanırım degil
birde malzeme listesi paylaşırsanız çok daha iyi olur du
Veri nice
please make the process for soldering
Bonjour je vous demande s'il serait possible de me faire connaître quels sont les composants électronique pour fabriquer un détecteur de métaux à double bobine je vous en remercie
Very good
How metr under eirth //??/5cm ...or...50.or.500cmm??
how much is your detection depth limit????
what for a w g of 50 turns
Hi sir can u plz tell the exact diameter of wire that u used in it for 50 turns
How many turns of coil is that? And what size or cm? Thank you in advanced po. But we need to know it tomorrow. Thanks
Pleassseeee answerrr
What size is the wire?
50 turn and 5cm diameter
What is the size of coil? 22. 25. 26?
@@keziahfaithbalois2301 have you figured out what is the exact size of copper wire?
thank you 👌👏👍❤️
Circuit Diagram Please?👍
Can it detect gold or silver😶😶😶😏😏😏😏
sooo where do you solder the cap's or the resistor? if your gonna show us how to make it then show us... don't just poke some components through cardboard and expect us to know how they are set up.. I mean if we knew that we wouldn't need to watch this eh?....not all of us have ESP...
que segunda-feira mais boa escutando músicas antigas
How increase the depth
hello sar..apne ye bana to diya.but esko aesa banane ka he ki ..metal detec na kar paye ..ye posibal he..
ishki price kya he
This is not working for me. .i am using 51k resistor & 1/4 watts. . .but it's not working
Noise is not clearly coming ,what i do.?
Put an LED then lol
Sao lại không làm máy dò tìm kim loại dễ nhất
What the range
احسنت vere good
Sir is se Zameen me kitne gahrai me kaam Kari gi
is not clear how to connect components under the board. Too fast
How make it bigger?
Huherko If you want longer range then wind the wire much more times.
Sir which copper please send me the name
Plz vary nice metal detector circuit nd part name
I think he stopped using arduino
Love u bro plz deep reng nd vary nice metal detector circuit nd part name
Plz circuit diagram
It's only the sound of buzzer. Test plastic and metal object the result is same!!!!
Скинь схему етого детектора

Svp donne moi le schema
هل توجد دائرة تعطى قوة مدى 20 متر تحت الارض؟؟ i ask about a circuit gives 20 metres deep
بدك لكم متر قلت هزا حلم غيرك كان اشطر منك 20 متر الداءرة اللي بتكشف ل20 متر بتكلف 100000 دولار يا شاطر بقى ما تحلم وتصدق كل ما تراه ب ب
i want circuit detector 20 metres deep
gamal learn you need a bulldozer with it my friend
20 cm is enough
Dig hole 19.9 metres deep then try it. Wear hard hat for safety.
lol, ya but that is a massive bolt, what about a diamond ring? i mean the bolt i can go to home depot and buy , lol ...
No schematic? Pointless for those of us who wish to build it
