After 90 seconds I had to pause to catch my breath.
But, this video was just what I was looking for.
I think it's great that you use a breadboard, it makes the project much more approachable.
Actually, I do metal detecting as a hobby and there is a real use for short-range detectors. They're called pinpointers and they help locate the exact location of an item in a pile of dirt you dug out (or help inform you if you failed to pick it up with the first dirt shoveling). Just thought id inform you if you weren't already aware :)
What are these exactly? Readily-built circuits or components? (refering to short range detector)
@@josephj5864 They are readily built devices little metal detecting wands you hold in your hand and wave in through the dirt clump to find the metal object inside. Look up 'metal detecting pinpointers'. They also make waterproof ones that vibrate instead of make noise.
I now understand how the detectors work (in principle). On youtube, this is by far the best explanation I've seen so far.
Great video as always! wish I had found you back in the school days so could've owned those science fairs.
Perfect! Thank you. I still have ALOT to learn about the world around me.
Great build
Very interesting! It would be great if you could slow down your talking just a tiny bit though xD
Wow you’re smart. Good on you!
dude you are awsome. keep thinking of those ww2 metal detectors and how they workd with no chips n bits
I paused the video so that the narrator could rest
impressive memorization skills. note to self. this is a KSL news endorsed channel via twitter
I think it would be really cool to see some of Tesla's inventions, such as the famous Tesla coil, his turbine, or his oscillator.
Very interesting! It would be great if you build a more powerful detector to search for stuff in the ground
Last week's build is going to be hard to beat.
+Ben Belanger yeah haha
Good 💯 may you make it more sensitive and more deeply
very well done
So if I use a thicker copper wire I get a better depth reading? In other words I have better search capabilities for metal in the ground
back for an update mines working great explanation i didnt have to go to diagram to put coil and speaker on it :)
Can you make a coil gun
Thank you I guess I will buy one.
you have quite energy mate. keep going.
This is so cool! I love this channel more and more : )
Yes, how do I get a coil wire stronger to pick up metal signals deeper in the terrain or ground?
You left me curious about that other, better, more complicated circuit you mentioned.
I have a question to ask you. Is there a reason why you set the number of turns of the coil to 200? Also, is there a reason why you set the diameter to that extent? I would like to know if there is a related formula.
Short answer: to get the desired inductance value of the coil.
thank you!
So... using this design you can make the metal detector discriminating, so it can tell the difference between certain metals.
In order to do that you simply place an adjustable capacitor or a potentiometer in parallel with the coil.
As potentiometers and varicaps that have wide ranges of values are best.
A detector with multiple coils in a grid array , for example 60 coils by 60 coils may be able to show a visual pattern on a screen at the same 60 by 60 resolution, also you could have an inline detector with potentially hundreds of coils in a row, this attached to a wheeled vehicle ,driven in a straight line the data from this could then be recorded and an image could then be shown, it is likely the coils would interact with each other but I wonder if they could be shielded, to stop the interference.
3 inches is perfect. thats all i need to find the loose metal parts i lose in the thick grass outside
thanks a lot... thats great.
WOW, your channel grew fast.
+DangerousPie03 haha yeah xD I get around 700-1000 subs a day now :D
Keystone Science That's absolutely amazing. I guess that's just what happens when you make such awesome content.
+DangerousPie03 awe thanks man! :D
+Keystone Science ,,,i wished you demonstrate how to make metal detector with cd4011 and cd4023 ,,,i found it in kavmaster.ru channel but i doubt if this will work,like a coin detect in 90cm and a big stuff for 2-3 meters ,,,i found this channel great,,, thank you
Great video ! Thank you!
I would like to see a high end metal detector
How does metal detectors extinguise the type of metals?
could you build a more powerful detector to search for stuff in the ground?
this is one of my favorite channels. Keep up the great work man!
so the coil is waterproof right and can u make a toturial with the better circuit?
RYU47376 It should be the same as this but beefed up. Just google schematics or tutorials and yes, the coil is waterproof the circuit is not.
thank you
So with everything you did if I get a thicker copper wire with more strands I get a search capability as far as depth?
I'm glad this isn't like the guy attempting to make a detector out of a transformer for a lighting tube.
I want to see more of your videos!!
esta muy bueno el detector de metal amigo
Awesome and creative job man keep up the good work!!!!!!!!!!!!!
Is there any way I can had an LED in the circuit to notify when the coil detects a metal?
I would like to see you build a induction coil!!!one that would be capable of heating a 3" pipe or crucible
this video is really cool and interesting
very cool. how can you build a functional detector for actual use finding stuff?
This channel seems to be growning pretty fast so if it stays at this rate and you keep making videos like this then you should be at 1,000,000 subscribers pretty soon like 1-2 years the average is about 10 years for 1,000,000 su subscribers
very good show I hop that god help you to reach your wishes
Hi, thank you for share with us.
DUDE I LOVE YOUR VIDS
THERE SO COOL
KEEP IT UP
I suggest you need to reduce the Voice volume.
because when you talks, I hear *audio clips* (distortion).
How do you modify a cheap metal detector to make it as powerful as you could and accurate for silver and gold
thank for your video are very interesant a frend from mexico
Saludos desde Perú tierra de los antiguos dioses precolombinos incaicos
Easy tiger, my brain nearly exploded.
Would you be willing to help make these for the school board? I have a housing i could make to go along the doorways. It would be a fairly cheap option for them to install to increase safety
Can u make a video or several videos where u explain every electrical component like capacitors,transistor,resistors etc .Explaining how do they work and when do you need them in your circuits.
How to make the gem deteror at home, can make ? Please tell me
great video! you could try to make a railgun
Yes, how do I get a more powerful coil to pick up a signal deeper in the ground, say about 30 cm deeper?
hey what about going less simple to make your own detector with knobs to fine tune the signal with depth detection
How would this design have to be altered to make it capable of detecting ounce or so heavy metal bits from few inches below surface of the ground?
Is there some tool I could use to turn the strength of the signal going to the speaker into useable computer data instead, so I could pair this with a raspberry pi.
Electromagnetic levitation next please :)
so how would you output more power at say 17 khz than another coil running at 17khz im trying to understand how you could increase the emf in a specific khz range or would it be fixed for each khz and then the shape of the coil dictates the power over a sustained distance so a larger coil would run 17 khz but would hold more emf for longer than say a smaller coil running at 17khz is there any way to add more power to boost emf ?
I have a big coil from an electric motor, should I use that?
I have the same tweezers as yours. Even when I live on the other side of the earth.
if you use a lighter it will burn off magwire insulation, it is flammable.
But it will leave an oxide coating which will still need cleaning off.
Thanks for sharing. I need help from you, I won't use metal detector for my project thats need more than 3 fit detecter range can you help me out.
Would it be possible to use a frequency generator such as a phone app, then amplify signal with audio amplifier and connect to coil and speaker??
What this tool you use to calculate the inductance of the coil
Hi! Can u please make a manual longe range gold locator? Thanks
What if I wanted to make a metal detector 12' wide?
Thanks a lot !!!!
And your videos as quite amazing
Panalo/The best ever
You should make a multistage coil gun.
I like. Thank you. Any thoughts on building something regarding sight or vision? Like night vision goggles or a optical tel
I have a question to ask you. Is there a reason why you set the number of turns of the coil to 200? Also, is there a reason why you set the diameter to that extent? I would like to know if there is a related formula.🥲🥲 plz ㅠㅠ
How to make a metal detector without speaker or buzzer with led for indication only?
can u plz tell me if we can use a 5v buzzer instead of a speaker?
hey if you are using buzzer and not a speaker you need to put 100uf capasitor and not 2.2uf
tjis is tested by me. it worked. i want to see your reaction.
Helo! Keystone Sc, to be honest, your video will only help those who have the basic knowledge of electronics. What do you have for us who don't have the basic knowledge of electronic? I got an Idea! Make another video on how to make a metal detector using electronic parts from a broken electronic devices like radio, tape recorder, stabilizer, refrigerator, TV etc n etc. Pretty Plz! TY
Do you have a schematic for that other chip you used? I have a chip with a PWM signal generator, checker and modifier. SG3525A. It's an 16 pin chip. I'm trying to do the same as you did just to see if I could. I can't getting it working and maybe your implementation will give me a clue what I'm doing wrong.
Do you have a data sheet for detector device components 20 meters away from gold or blanks
what capacitor was it? I heard the first one is a 2.2 uF but what voltage? Does it matter
nice one
Could you help me make a metal detector and voids at depths like 20 meters underground
I've made this but the audio output is outside the audible range what to do?
P.S.- I've used buzzer instead of speaker.
Please make another more informative and slow way of how to make a metal detector
It should be smaller and easier to carry but, it's good.
Love u bro plz i am made metal detector in home plz deep reng metal detector circuit nd part name plz send vdo
How do you increase the range exactly? I'm sorry I'm not a very circuitry literate person
hey keystone science can u tell me circuit using relay and sensor without any controller
how many meters can it search for metal
Nice
how about a plasma lighter,, i would love that
amazing
