Metal Detector "Home made" first project

This type of metal detector uses two wire coils, one which is large (detector coil) and one which is small (reference coil). The two wire coils are each connected capacitors to create two circuits that oscillate. The detector works based on the resonant frequency that has been set change when there is a metal object is located quite close to the search coil sensors.

Aaron,As an electrical engineer I commend you on both your knowledge AND presentation. Very, very well done! Have you tried a "live" wire detector? It would be a nice addition (maybe you have but I didn't look into your work yet). In addition, I believe the "Soft Iron Core" you suggest is Nickel-Iron. Very high permeability and yes, hard to get and expensive. Running higher frequencies utilize the high permeability of the ferrite though.Just had to say what a great presentation!John

Great job

[@InsanePlanter]

very good video please do more as very clear and complete

[@IndustrialElectronics]

Thanks, I will

[@patprop74]

+Aaron Bern Hi Aaron have you made the updated video to this yet? I am a complete newbie , but I would like to try to make this metal detector as a pinpointer.

[@AndreiGrozea]

Done :D And it works,great job !

[@heddybaby1000]

That was awesome

[@mykeeX13]

Well done my friend..

[@leventdundar1754]

thanks a lot very clear

[@johnlaney276]

Like your choice in music

[@josipmesic908]

Works great, thanks

[@kenny444tourist4]

Just a tip: when you measure resistors, do not measure your body too, take one thumb off the meter lead, but 10/10 for effort.

[@fredymredy]

he do that i see to :)

[@abdulrosidin5181]

Bangkit mr bikin trus vidio tentang detektor yng banyak

[@apcer88]

very good video..please send more details about capacitor or blue print
and materials you use? tnks!!!!

[@sabu93000]

Nice n useful thanx for video.....bt it's works only around 8 to 10 cm can you tell me how it's work for around 1meter

[@coolyoutuber4319]

if it is a metal detector why didn't u placed it on a metal piece
why only on the supply lines near switch and the switch on
can any one answer

[@josepinillosv.1886]

Se prueban las resistencias tratando de no hacer continuidad con las manos porque tienes otra lectura

[@power5able]

Is the negative supply directly to ground or something? I'm not sure on that

[@Marcoflautista]

Good morning , thanks to your video I managed to finish the project , but my parents do not find the VR1 and VR2 , the 2k5 and 2k2 put a 100r , but led the league does not regulate , could you please give help , much quarreled God illuminates it .

[@mdshakibmunna4678]

All parts name me help very inoden me

[@robinrwilsonsauls]

Brilliant-but can you turn off the Club noise-it's horrible. You are awesome, but that noise sucks!

[@manueljoseacosta]

hello friend thanks for your great circuit, you could tell me please
1. which is the maximum depth reached?
2. I can use a buzzer instead of a LED?
GOD bless you!

[@IndustrialElectronics]

Hi mate,
Detects up to 10cm depense how many windings you gonna use and which Zener diode.
You can install both, a buzzer and LED.
Use this buzzer if you want:
Dimensions: 11.6 x 11.6 x 7.5mm
Lead Pitch: 7.6mm
Current consumption: 30mA
Sound output at 10cm: >85dB
Frequency: 3100Hz ±500Hz
Housing material: PBT
Operating temperature: Â-20°C to +85°C
Storage temperature: Â-20°C to +88°C
Rated Voltage: 12V
Operating Voltage: 8 to 15V DC

[@Ray-mm6en]

Very nice. I was wondering if something like this can be used to check Halloween candy for things like needles or razors?

[@pushpakkothekar9271]

Sir Aaron Bern can suggest me which two inductors to use instead of two loops of wire!!

[@thesagun7]

what can be done to make it work for 1 meter of range???

[@sugamgoel9196]

our circuit is not working may be because we have used coiling wire of very less dia as compare to 0.3mm plz suggest something to make it work

[@sarathchaminda4911]

Sir do you know how to make underground gemstones detector circuit boards like this is

[@pirusyasayesh5178]

Hello my friend. Please make pinpointer new pro verjen add buzzer alarm bib bib bib ||| bbbb.
Thank you. Good luck

[@charlymh9480]

De qué diámetro es la feria y el largo me puede decir se.

[@pedrojunior9505]

Hello my friend , in the place that led I could put an entry for headset ?

[@ALmer7e]

hi pro
Are you can get me the circuit map ?
please I need for my project in college
thank you very muck

[@tauhidullahshah7280]

can we connect it to the Arduino?

[@yasiralvi114]

how we make more sensitive one and plzzz

[@sanjaykushwaha823]

sir can you tell me about the coil core material

[@maheeshmunasinghe5505]

how did u do the calculations?

[@samodelkin9584]

Throw schemes please

[@ianbiggs4553]

how much did this cost you ?

[@vobinhthu5299]

Thanhk

[@iduktechblog]

amazing skill, thumbs up and a sub from me

[@joaoalves2281]

[@dawithaile3159]

this is super hard to make
