Thank you very much! Your detailed instructions helped me alot building this great MD.

For anyone who is wondering about the coil, its very important for the coil to have the right amount of windings, ie the right inductance.
Otherwise its not working or only in a narrow frequency band. That was the case with my first coil, that had too much inductance, ie too many windings.

I wound the second coil by adding/substracting windings until it worked on both ends of the 2K variable resistor, which alters the pulse width and frequency.
That improved the sensitivity significantly.
The larger the coil, the less windings are necessary, a coil with 22cm and 25 windings seems to work also.

I'm Brazilian from Brazil and I'm an electronics technician and I researched several detectors and I found yours and I liked the simplicity and perfection, and I'll put together congratulations.

Thank you for making this video. I have adapted the circuit with the NE555 and/or relay(remove the buzzer&4R7 with 1kohm and jump C1815's Collector signal to pin2ofNE555) by using the negative signal that come from the transistor, so the next 555 section will generate an output pulse(with the RC duty cycle ratio) anytime when the metal object is in-range. ♥

Design a 'pointer' that is so reduced in power it only detects from 10cm or less. These types are not so good for general detecting because you will sense garbage at 100cm and spend all day digging metre-deep holes for junk. That being said, I'll still build it as it's a good detector and a nice project to build. I'm sure it has good usage.
I will also say that you have perfected the art of the Youtube 'Circuit Video'. Very clear showing placement of components + A link to the necessary files that actually works + A valid schematic at the end. +10000 likes!

Thank you for making your findings public. Great work! Dubri

You are the best example of the saying that knowledge increases as it is shared, you answered all the questions without getting bored, You said you'd be working on a new, more deeply perceptive detector, and when are you going to share it with us, thank you.

Terima kasih teman ....saya sudah berhasil membuatnya...semoga ilmu yg kamu berikan menjadi pahala saudaraku...

Thanks! i made this detector to from another circuit, and realised they had totaly wrong value on the resistor from pin 7 and 8 on 555 (1 kohm). The irf mosfet was glowing hot. Then found other circuit that used 47kohm, and that made it allot better, and even more sensetive. will try even 100k as you use, though i still got it on breadboard :)

Thank You Very Much ❤️
I made this circuit and found that the IRF730 mosfet was very hot.
the reason was the first resistor 1kohm between ic555 and 2k pot.

this resistor affects the oscillating frequency of the coil.
you must replace it with 100 or 220 ohm to increase the frequency and reduce the power consumption.

Good work. I want to thank you for these efforts.. A work suitable for beginners. They may have a chance to try it.. Remind me that this Russian was developed by an Algerian with the property of isolating iron.. Good luck.. I joined your army

[hobielektro]

I really like this it is very suitable for searching for gold and metals

[tromsifirko]

Köszönöm a precíz és pontos leírást, képanyagot. Tökéletesen működik, megépítettem. 👍

[luisbarreiros]

hello we here in Brazil we do a lot of detection also congratulations by the circuit I will assemble mine.

[mousaqadry]

it is a very magnificent effort you did thank you so much
but i have 3 questions
1- is the sound volume strength indicate the distance between the metal and the coil ?
2- what is the maximum detection distance for this circuit?
3- can i replace the speaker with a relay if yes what kind of relay ? (i need something to make trigger on metal detection so i can connect the circuit to the Arduino digital pin )
thank you again

بارك الله فيك هذا أفضل فيديو يوضح طريقة صنع جهاز كاشف المعادن
أتمنى لك مزيداً من التقدم والنجاح

[blakedcake]

im still trying to figure out how you distinguish metal from that induction pulse with one opamp chip. Is that a lowpass filter on the first opamp?

[userall-qxll]

sister if you put more wire it can give you more range please answer love you

[WebMasterHosting]

Hello! why there are four wire ends in the coil? (10:26) how did you join them together to make only two wire ends? in series or in parallel? Thank you

I love intelligence, ease, good photography, and explaining the names. You deserve a like. Thank you. You are also cute 😊
