Hello sir. This is really an interesting project but it seems to be working only with magnetic metals like Iron and steel. But what about non- magnetic metals like Aluminium, Nickel, Gold or silver? Can you modifiy this to work with all Metals? Love from India ,❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️
I really like the format of this video, well done! I like that you included the LED option as I have friends that are hearing impaired. Personally I would like to see an OLED displaying battery level and a "relative" number indicating the "strength" of the field. This would give the user a rough idea of how deep the object is. Also, a way to extend the sensitivity for better depth detection.
Or a metal detecting pram... you know with all ur stuff inside so can can dig and to put all the junk. Find a target and then just rock it over the target to pinpoint etc. Pinpointer disguised as a bottle.
good work Sir, try to design one that can sense metal from a distance of 50-70cm - then it will be much more valuable for coin collectors inside ancient graves 👍👍😄
Good question, i'll try to explain as best I can. Yes, anytime you have electrons moving back and forth, the oscillation disturbs the electric and magnetic fields and some energy is released as radio waves. (i think the E and M fields are what you mean by "ether". You can think of a "FIELD" like a pool, and an oscillation like dipping your foot in the pool. When you push the water down, you create a "DISTURBANCE". Before it was all calm and peaceful, but now you made a big splash and disturbed it. The water molecules AROUND the water molecules you pushed down ALSO get pushed down BECAUSE water molecules like to stick to one another. Then the water molecules around THOSE molecules get pushed down, and the disturbance spreads outwards, or "PROPAGATES") However, the coil in this video doesn't emit radiation very well (aka, it's not a very good antenna), so while a little energy leaves as electromagnetic radiation, the energy in coil's magnetic field is mostly dissipated as heat through the wires of the coil. Hope that helps! And... I'm not sure what you mean by "digital," can you elaborate?
Benn building this as the oscillator ckt as well as the pcb version, but no luck with either one. Put the scope on both but I am not seeing any 33 khz (or anything close) on the scope. Any ideas?
Why not use a BFO? Op-Amp with phase inverted inputs is no output (noise cancellation tech right there), up or down beat depending if the material you detect is tuning (ferrous) or de-tuning (nonferrous) the coil?
Would it be possible to have a PCB that is "only" coils similar to the existing coil, and then stack PCB coils on top of each and then solder them together to have a more dense array of coils? How much of a difference would there be if they were connected in series vs parallel when stacked??
are you sure that q2 transistor is PNP? it's so strange that without a signal a pnp goes off, it should go on and let current pass. I understood the role of q3 but i can't figure out what q2 is doing. please let me understand :)
can someone share this project in easyeda? for some reason when i try to run it i can find spice models for the bjts and it says no ground for some components...
Does everyone know if there are any tools available that help to designing a pcb trace? For example creating coil with specific inductance/resistance, antenna with specific frequency, etc
I like This Video Brother. Try to make Metal Detektor using Arduino for Controling Oscilator and Logic Gate, use Frekwensi 1 khz - 5 khz using arduino.
The 22uF caps joined to the inductors form an oscillator and together they oscillate at a predetermined frequency defined by their respective component values. The clever bit is that the two Inductors are also coupled (via magnetic fields) and interact. These interactions chnage when ferrous material is nearby. The 22uF also prevents DC current from flowing into the transistor base which is the job of the parallel resistor. the capacitor only allows high frequencies to pass into the Transistor to turn it. Lookup LR oscilators for more info. resonant frequency is defined where Xc=XL; Xc= 1/(2.Pi.C.f) and XL = 2.Pi.L.f. Hope that helps.
So 2 years and nobody helps a guy out? I'll say it *sensibility* is "good reasoning" and *sensitivity* is "ease of "triggering an event". BTW, great video!! I wonder if our author wants to scale this by stacking 2 PCB's (each w/ 4 layers) with suggestion for a user made feedback coil (off pcb)?

This is the best explanation I've come across so far, much appriciated the great effort you've put into this video 👍

Idea: make a pair of metal detecting shoes! 😁 So you can find treasures while just causually walking around 😉
Just don't wear them or take them if you are travelling by plane.

Just got here from email notification
That's neat
Nice sir. Now we can make this within 10 minutes. And fortunately no arduino this time.
Made it long ago 😃. Though its range is small, its a cool circuit and fun to build one.Thnx for sharing.
good work Sir, try to design one that can sense metal from a distance of 50-70cm - then it will be much more valuable for coin collectors inside ancient graves 👍👍😄
Thank you, but can you explain what are those Capacitor used for ?
Same question
Thanks! Been looking for an explanation like this!
4:26... Great explanation of the coil circuit... Would be nice if there was a jumper to use the onboard coils or external coils.
Can you make a smart glasses with your transparent display
Great video, its really helpful . how much cost of this PCB, with relay ( NO+NC+Common).No need Buzzer.
The theory part is really awesome!
This is great, thanks for sharing mate
Random question, does an oscillator emit any kind of frequency in the air/ether or is it just digital?
Good question, i'll try to explain as best I can.
Yes, anytime you have electrons moving back and forth, the oscillation disturbs the electric and magnetic fields and some energy is released as radio waves.

Nice project 👌 and thanks for all

Bro please tell me which software you use for editing video and creating animation 🙏🙏🙏🙏🙏🙏
Waaaw god job❤️❤️❤️❤️👉👉👉👉👉👉
Why not use a BFO? Op-Amp with phase inverted inputs is no output (noise cancellation tech right there), up or down beat depending if the material you detect is tuning (ferrous) or de-tuning (nonferrous) the coil?
Can you build a mobile phone signal booster to use in rural areas? I couldn't find any proper tutorial on the internet for building such a device
Very good explanation 👌
Wow... the video was something...⚡⚡⚡
Excellent explanation of induction and oscillator circuit!
How to increase sensitivity? More current through big inductor or/and more windings?
Bigger coil area + more windings, but from my experience, area is more important than windings ;)
Would it be possible to have a PCB that is "only" coils similar to the existing coil, and then stack PCB coils on top of each and then solder them together to have a more dense array of coils?
How much of a difference would there be if they were connected in series vs parallel when stacked??
That should be tested. But maybe is better to amke the coils out of copper wire
@@ELECTRONOOBS Yes, but one benefit of your current package is that is is more plug-and-play. Good for noobs.
are you sure that q2 transistor is PNP? it's so strange that without a signal a pnp goes off, it should go on and let current pass. I understood the role of q3 but i can't figure out what q2 is doing. please let me understand :)

Excellent video.
I absolutely loved your presentation , thanks for your hard work.
By the way, which software do you use for animation? Thanks
100% agree, this was SUPER articulate
Please make serie videos on the easiest way to making 3D modeling for printing.
Does everyone know if there are any tools available that help to designing a pcb trace? For example creating coil with specific inductance/resistance, antenna with specific frequency, etc

Very informative.. Thank you
Hi, What software do you use for this beautiful animations 🤩 ??
Hola cuando haces un detector de metales más grande y potente
Great video keep it up
Hey, pls make a diy inductance meter
what is the function of 22uf capacitors on the loops.
The 22uF caps joined to the inductors form an oscillator and together they oscillate at a predetermined frequency defined by their respective component values. The clever bit is that the two Inductors are also coupled (via magnetic fields) and interact. These interactions chnage when ferrous material is nearby. The 22uF also prevents DC current from flowing into the transistor base which is the job of the parallel resistor. the capacitor only allows high frequencies to pass into the Transistor to turn it.

@@robertjones5395 thank you so much
hello friend, could you make some of your videos dedicated to the TM35 module with arduino?
maybe a good mail finder for woodworkers !!
Why use a PCB coil when a simple coppercoil would be cheaper, more compact and perform a lot better?
How much cost of single pcb?
Nice
Could you make tutorial about converting 220 AC to 12 or 5 DC 🌝
