Nice...👍 What about Lazer locator detector.. for gold..
Halo kawan . hi my freand
Can the two capacitors be replaced with ceramic capacitors or plastic capacitors with the same numbers???
يعطيك العافية شكرا الى مجهودك بس سؤال صحيح انو ما برن على الذهب الرجاء الرد
میشه بجای خازن 100nf 100v از خازن 2A104J استفاده کرد
🤩🤩🤩🥰🥰🥰🥰🥰🥰
Sir, can i use electrolyte capacitor instead of ceramic capacitors?
Ok
no, you can't use electrolitic capacitors on this project.
الله يبارك فيك عمل في منتهي الروعة ً كم تحتوي البطارية من فلت و شكرا
سلام استاد خسته نباشین الان چند بار که اینو درست میکنم صدای بازر میاد ولی ولوم کار نمیکنه میشه اشکال منو بگین؟
Esse é bom
Can I use 0.05 copper wire to make a coil? Answer please..How many wire cycles
0.5 you mean
Hola amigo ke calibre es el cable de la bobina el trimer ce puede renplasar por un potenciometro de 100k a cuantos voltios travaja el detetor grasias
عمل جد رائع رائع شكرا لك
ممكن مواصفات الكول او الملف تكرما
Hi sir i do the same lik you do but the bazzer kip bazzin with no sensviti what is the problme help me pless
For gold, how.......?
This circuit has some flaws, it will be very unstable. Take note that is may or may not work. Some may be able to make it work. There are metal detector circuits on the internet that are working properly. Please take note the first stage of the circuit (transistor and buzzer) is wired wrong. Also, the soldering makes the circuit very unstable. Source: over 35 years of electronic engineering.
Parece simples e eficiente para iniciantes como eu porem eu fiz o circuito em um app de simulaçao e acusou que o capacitor 1 estava em curto. Se puderem me ajudar com isso, eu agradeço.
@@rtm5296 Hello there... I really want to make this project even though it might not work... could you please tell me which capacitor is capacitor 1?
هل هذا يكشف الذهب
@@user-dl5jv3cr7y , You are asking if you can find gold with this. Well, i would say yes and no. Let me explain. Yes you can find some gold like rings and chains. But if you are looking to find some pure gold nuggets from a mine, you may not be able to detect much. If you wish to find gold nuggets, you will need a much better metal detector such as a Minelab detector.
the battrie 9v?
Hello, I've made this metal detector with 2 changes.
1) i didn't get 100nf (100v) capacitor. So i used 100nf (160v) capacitor.
2) i made coil with 0x, 22x, 72x windings.
But now metal detector keeps buzzing all time. Are those changes that i made is the problem for it keeps buzzing all time? Please suggest an edit. Thanks
i have a same problem.
Ur shuwar pls dis dargrm sen me
use the varistor to reduce the noise
I think you should use a bigger variable resistor then trim until the sound stops'. You can instead add a resistor in series with the variable..
@@sa3eedz568 please itis a potenciometro or one resistence of the colors it go whit resistencia variable thancks
Will you please attach it diagram for the detector.Thank you.
My brother, in a piece that does not contain its name, and you will make two pieces of it, but you love and respect their son and thank you
And works it with gold ?
How many volts should the battery last?
3.7 to 4.5 volt
CAN WE USE transistor 13003 RATHER THAN bd 137 BECAUSE I DON'T HAVE IT
Hello
Thank you for your comment
You refer to the transistor similarity table.
Of course, with a similar transistor, its sensitivity will decrease🙏
هل يكشف الذهب ام الحديد فقط
Can I detect wooden material with this detector
Bro it is a METAL detecotr...so.. no you can't
Can you make a way to cover 5 meters under the ground?
Try many times its contineous sound
Hellow sir goodevening,
Sir copper wire is 0.3mm you said but how many rounds we want to do, please replayme sir, sir you have great job for us thank you
Selamaleykum vidyonuzu defalarca izledim tek anlamadığım nokta bobinde neden 3 kablo çıkışı var bana dönüş yaparsanız memnun olurum saygılar
arkadaşım merhaba
Fikrin için teşekkür ederim
1_Ser Sim (ilk 20 turun başı)

سلام اگه لوپ ۳۰ سانتی متری بسازم برای این مدار بردش بیشتر میشه یا نه!؟اگه بیشتر میشه بیزحمت قطر سیم لازم و تعداددورهاشو بگید
سلام
ممنون از کامنت شما
من امتحان نکردم ، فکر کنم زیاد تغییری کند
هفته آینده یک مدار با برد ۲ متر آپلود میکنم
@@creative4979 یدونه باشید منتظرم 💓💓💓
My brother, my friend, I want to bring you with me. I took the pieces encoded 1003 1401. I died. I’m looking for it. I can’t find the piece. Can I replace it with another piece?

استاد خسته نباشید خیلی جالب فقط با چه ولتاژ کار میکند
سلام ممنون از کامنت شما
3.7 تا 4 volt
دورود دوستتان داریم
20x? 22x?
How Many coils do You use for this detector
ruclips.net/video/jOQeGT2YtJE/видео.html
I was completely build your 2 project but project aren't work anyone ...so what can I do ?...
I have the same problem did you solve it? thanks.
wow....how to increase that sensibility??
Can i use tip41 instead of bd137
Yes
Better not.. try it tho... he has another video with a simpler meta detector that uses tip 41.. so try making this one instead
سلام لوازمو از کجا باید تهیه کنیم
Teacher mayyou put the diagram for made the proyect i have de component thanks
How many volt the battery and the coil. How many turns and how I can increase the noise
If by noise you mean depth that the thing can detect... i dont think you can.. it is 3.7 to 4.5 volts.. and there are 2 coils of 20 turns each.. then you connect one of the leads of each coil to make a center tap and..yeh thats all.. follow his instructions
sir I do same process to make but we adjust the variable then it not working what happened 😭 please reply 🙏
Hello my friend, thank you for your comment
My friend, move the coil bases and test again😉😉❤❤🙏🙏
Hello there.. by "bases" you mean the coils' leads? For example lead 1 to lead 3 and lead 3 to lead 1?
HOW MANY TURNS IN THE COIL BOBINE?
Hello
20 first round + 20 second round, total 40 rounds🙏
Sir it is really effective to detecting gold?
Hi dear friend
Thank you for your comment
In general, metal detectors react to all metals, and gold is also a type of metal.
Dear friend, if you are looking for a strong metal detector, be sure to watch the channel's new movie😉❤❤

استاد الان من فک کنم ده بار اینو ساختم ولی بازم فقط صدات بازر میاد ولی کمو زیاد نمیکنه صدای یکنواخت داره مشکل از چیه
اون مقاومت آبی رنگه، بالاش یک پیچ داره اون پیچ رو کم و زیاد کن
Bro can I use 27 gauge copper wire for this project
Hello
Yes you can use but you have to adjust with a variable resistor
Is the wire behind the TV screen sufficient for its purpose?
Sim também dará certo é um ótimo fio.
سلام استاد خسته نباشین من چند بار امتحان کردم نشد البته با ولتاژ ۶ امتحان کردم چیکار کنم خیلی میخوام اینو درست کنم
ابله اینجا فارس میبینی کی جوابتو بده
does 0.4 mm coil work?
Hello my friend
Thanks for your comment
Yes, it works with 0.4mm, but you have to increase the number of coil revolutions by 0.3 to 0.4❤❤🙏🙏
@@creative4979 thanks a bunch friend
@@abdelfettahbenhamza3234 Brother, did you make this project? If so, tell me how it works. Is it working as shown in the video? And how many turns of 0.4 mm did you make?
Ke tal amigo digame como puedo recivir. Ece circuito?
Tranzistor replacement BD137?
As it says.. you can use bd 139 instead
هل ممكن استبدال ترانزيستور 137bd.....bd135....
Hola amigo,puedo usar un bt 137 en sustitución del bd 137…saludos y bendiciones.

Amigo use o bd 139 se tiver.
هل تقدر تعزل الحديد
Thanks a lot for effort
Is this detector effective for gold
Thank you in anticipation
Ok 👍👍
@@creative4979 Thanks alot
لو سمحت انا انشا الله اكبر داعم للقنا بس. عندي طلب في قطع مش موجود اسمها لو سمحت ولله اني بحاجت ها ض المشروع
Muito bom
Will he reveal gold my friend? How is the coil constructed with three wires?
ruclips.net/video/jOQeGT2YtJE/видео.html
Hello there.. so you are questioning on how from 2 coild it ended up having 3 leads... so what he did was to take 1 lead of each coil and solder them together to create a center tap.. search on the web for what a center tap is to understand it better
Share Layout diagram
Is it fine to use .025 ciol ? With the same 20x 20x ?
I think you can
Inductance changes tho... I am not sure if you can with 20 turns.. find Inductance formula and find out or.. just go and search for a coil Inductance calculator...
Gold Detector Scanner, Underground making you next video
Hello
I will definitely do it at the first opportunity🙏🙏
good
you vidios good im srilanka
Or bd139 ?
Ok

Please give me a daygram
Circuit please
Please sir give me a circuit
Are your did not 60cm deep search metal detector circuit wiring diagram please thanks for your ( im srilanka )
Hello my friend
Thanks for your comment
I will definitely upload at the first opportunity
@@creative4979 im waiting for the 60cm depth
The 20cm works but wasnt clear coz the coil wasnt perfect lol
Brother I did today but it doesn't work
My brother, a small request, but in one piece, you did not put its name, and I used two pieces of it.
Hello
Which piece did you ask?🙏🙏
All the necessary parts are in the description of this video🙏🙏
سلام ببخشید طلا هم تشخیص میده
100% ok
That's a battery or how much v
Use 3.7 to 4.5 volts dc
Queria ve se pegana na área da praia
not working for me
MERHABA BD 137 YERİNE BD 139 OLURMU
Diagram?
Ok so I made it and it kinda worked.. the range was half of what shown in the video but other than that the potentiometer was doing nothing... note that if it continuously beeps and the pot does nothing... you should change the position of the wires from the coil to work...if anybody can help me solve this problem.. I would really appreciate it..
Update... I removed the pot and somehow it still works..
What you did in the video does not correspond of the diagram on your instagram
How much is the battery please?
4.5 v
