- Make a microphone out of a matchbox and pencil leads. Listen to sounds and music from the other side of the house using this DIY microphone. Simple audio electronics project. You will also need a battery, some wires and clips, and a pair of headphones or a speaker. Fun and simple science experiment, and great to do with children.

Nice pfp
For those of you wondering, you can use metal instead of pencil lead. I've been experimenting with two paper clips as the connections and different materials as the free-floating part, and have found something that should be discussed. I first tried 3 paper clips stripped across the bridge, with 4 AA batteries hooked up to it in series. I could only hear loud bumps and buzzing. After experimenting and reducing to two AA batteries and only using 1 paper clip, I found that if I talked very quietly, I could hear what I said - but it was still bugging out my headphones. I then attempted a piece of aluminum foil folded accordion - style. It was so loud that it made loud bumps on my headphones and hurt my ears. The reason graphite doesn't do this is because, though it conducts electricity, it acts as a resistor; as in, it makes it much harder for electricity to flow through it. In conclusion, to use metal instead of graphite, you will either want to hook up a customized circuit to reduce the current, or, for those of you who can't, if you use a 1.5v AA battery with two paper clips as the connections and a paper clip across the middle for the actual microphone part, using a 200 ohm resistor (Or 220 ohm resistor) hooked up on the positive lead of the battery will bring the amps down to 7.5 amps, (or 6.8 amps) and will hopefully prevent your headphones or speaker from blowing out. SERIOUS NOTE: I am still new to calculating resistance, and this is all theory until I have a chance to actually get some resistors, so use headphones that you don't care whether or not they are destroyed, and DO NOT PLUG INTO AN ELECTRONIC unless you are ABSOLUTELY CONFIDENT that it is safe, or else you may just ruin ports on your computer or other device. Hope this helps!
cool,i use an old oxidised needle on two pieces of graphite as a semiconductor for crystal radios.

Can you make a time machine with two potatoes and toothpaste pls?
If someone does this at any time in the future they could travel back to, say, the 1950's and then it would have already been done by now.
Makes sense, I think.
He deosn't nee potatoes and toothpaste.
He can make one with a stick from a tree and a grill.
мisteг Rㅇьloχiдп Or like a leaf and an handfull of dirt, works for him too.
he won't make it coz he wants you to make that discovery. Stop trashing others, go and study.
Attach both sides of the battery to the "microphone" and you've got the basic structure of a railgun. It shouldn't be powerful enough to move anything, but crank up the power input by daisy chaining batteries and the smaller graphite piece will move down the line.

Oh, this explain why my teammates have bad mic quality... Thanks Dave!
“Consider wearing safety gloves” *as he uses an extremely sharp knife with his bare hands*
I am more concerned that he is using lead, around a knife. (If he cuts himself and gets the lead in it he could die from lead poisoning ;-; )
His bare hands ARE the safety gloves 😂
@@StiflingSky Pencils don't use lead, instead they use graphite. Using a sharp knife with no gloves though... yikes.
Thanks dude! Now i don't need to waste 100$ on a microphone. I can just use this super high quality microphone!
Let's see the real money!
Good
That's a carbon mic so your voice will be heard but other wise bad audio
Dude just go to a thrift store and get a gh mic
That's pretty amazing a microphone is so simple. I think when edison made his, he called it the carbon transmitter. To clarify in case it hasn't been discussed, pencil lead is made of a graphite powder mixed with wax and pressed into the familiar shape.
yeah,it works by modulating a current,i have an old one from the 1970's in yugoslavia,as yugoslavia wasn't as developed in a lot of stuff that america was(although it was one of the biggest forces,and had the second best army in europe)the microphone was something like you would see on thomson houston telephones way back in the day...

This actually works! If you wanna hear your voice clearly then you can make an amplifier with an electrolytic capacitor, a resistor, and and any Lm chip, you can see how to make one on CZcams also. Good luck with your project!
I just finished making this project. Now, the sound works. But you can't hear voices or talking, anything like that. You can only hear static when you tap on the box or lead. The "lead" works with graphite, because nowadays you can't find real lead pencils. Anyways, this was a cool project that I enjoyed doing. Well worth it! Thanks Dave.
Yeah, I was wondering how that can transmit speech, you need a diaphragm and a way of varying the resistance.
Did this for my science fair,worked out great!👌
That’s cool

Is this the mic that new gaming channels use?
I love how suddenly it kind of turns into an ad about headphones
^crap how am I getting more likes on this comment than I am getting likes on my youtube videos.
Y you people so love
Yep
I REALLY DON'T get it... this gets more likes than my videos because???
I made a slight improvement of this experiment.
Instead of using 3 pieces of graphite, I only used one.
The two supports were solid core, bared copper wire.
To stop the graphite from falling off, I put a tight loop in each of the wires, places the graphite through both loops, and then inserted into the box.

Where the heck are you gonna find lead pencils? They're all graphite!
they sell them in stores
blonde4fire
No, they don't. They're graphite pencils.
20alphabet yes they do here where i live they have graphite and regular oldschool lead ones they even say on the package .and as i just did a search you can still get them online
he means graphite because obviously there not gonna be real lead

How come there are no audio samples? Are a few taps on the thing the best you can do?
You can Talk to each other to
+Melissa Slone How do you use it to talk with other people?
Lau Bjerno yo dude its probably cos his audacity tunes are to high so he will sound like a different person
Lau Bjerno yeah, at the least they should have recorded farts in it.
Me and my brother made 2 of these, we put one in his room and one in mine. When our parents were mad at us or we had to go upstairs, we would put the earphones on and talk to eachother.
how good was the sound quality on a scale of 1 to 10? I want to make one myself
pretty cool, huh?
its a GREAT way to eavesdrop in on your siblings sleepovers!!!
Meanwhile let's just tap it and not demonstrate the actually potentially interesting property of transmitting something of use, like someone talking.

This is brilliant! I never knew lead could be used for such a project. Now I need some crocodile/ alligator clips to get started.
lame
MrHellrazer08 What's Lame?
DragonMinerToons He found the video lame. That's what he meant.
Indeed, same here. If and by the way, that is graphite, not lead, found in pencils. We learn something new everyday...
DTRE Sizzurp right.
I’ve been watching Dave since I was 4 so I’ve watched him for five years and soon six
Hey I made it for my science project and it actually worked!! Thanks a lot Dave!!
The carbon microphone is re-invented.
tadaaa
Well pencil lead or graphite is actually just a bunch of carbon atoms strung together in a certain way
it also has clay in with the graphite.

Song of choice: Roar by Katy Perry
Now all I need is a pair of pencils and a matchbox to officially become a spy
DaveHav: pretty cool huh?
Me: Yas, Very very cool. I’ll try
For those that think this is fake this actually works. But you can't talk through it, it just makes sounds when you touch it.
You should have recorded some sound from the microphone to give us an idea of quality.
How do I move the extension wires upstairs if I live in a one room house?
u dont
maina muchiri
I highly doubt you live in a one room house
We can talk also? Or we can only hear voice of tapping?
He is lie. I make that and I hear just murmured it sound like this:sssssssssssssss
***** I think I am not becuse I made all the same
Marin Šantek Maybe the lead wasn't flat enough
Charity Hopkins The graphite is flat only so the on in the middle doesn't roll, it shouldn't affect the performance of the microphone.
***** He said "Tap, talk or sing" and then he said "If you have two, you can talk to each other"
This would a great addition to “Prison Inventions for Dummies”
I would have liked to have heard the final result
Next week on CrazyRussianHacker.
ow you think so to XD
Stop with that.
A nice long length of unshielded cable!!
this doesn't even work... and you need like 50$ for all that wire
What a subtle headphone ad
“Your microphone sucks, are you using a potato?”
“MATCHBOX.”
Can you connect the led together so that you can move it around?
Needed to make a matchbox microphone:
Matchbox
Pencil
Sharp Knife
Scissors
Piece Of lead
Batteries
Wire/Lead
Headphones
Speaker Cable
Its not lead its graphite, you look so dumb saying that. Try writing with lead, you will fail and most likely be poisoned. Have a nice day
lead wont poison you unless you consume it directly. also,
We call it lead is because the Englishmen who first discovered graphite believed they had found lead.
@@SuperNinjaMan55 and because lead also leaves Mark's on paper
I don't have a house how do I do this?
What's the song in the background? I heard it in bfdi in TV wins dream island!
!
Sades SA-810 gaming headset is *pretty* good.
Sound quality MIGHT not be as good, sometimes it disconnects but it also comes with a microphone.
What to hide under your sisters bed
Davehax: *makes russian spy mic*
powered with a 9v battery, you can just tap the two leads together to get a tapping sound. If this "microphone" does nothing more than that, it's completely worthless. If it DOES atually transmit sound, why not let us hear it?
Instead of insulting , why dont u try it out urself ? It aint gonna cost a thing to do so
@@ender0998 It wouldn't have cost DaveHax a thing to show us whether his"microphone" transmitted sound. It would cost any of us time and energy to prove the hypothesis that HE presented. If you say something does something, why not show it doing that thing? Or better yet, why don't you build one and report back to us whether it works?
The microphone who’ll have a very bad quality since the signal is a square wave.
Its not lead... its graphite.
+Ame Nightcore You can lead a horse to graphite, but you can't force him to call it a pencil.
Dell Conagher Yeah but this is completely 2 different things. One is heavy and poisonous and the other is light and made of carbon. Its like apples and oranges!!! You look like a ignorant fool when saying a pencil is made of lead!!!! :)
Ame Nightcore No. Obviously pencils are made of wood. Why would you make a pencil out of lead? Not only would it be poisonous, as you said, but it would be ungainly and heavy.
+Dell Conagher You sir, are one of the best people that are currently sitting right on top of the internet.
Music Boxie Believe it or not, you're the first to say that to me.
Crazy idea: make a speaker and connect it to the microphone. You might be able to make several from 1 microphone, but you might need a more powerful battery to get a good sound.
I finally found what I'm looking for, Thank you, God bless
it's not lead, ti's graphite
and graphite is just another form of carbon. like diamond or charcoal
C based lifes 😂
@The Technocrats thnx for sharing your Knowledge to us
Truth
it's called pencil lead because it used to be made out of lead and the name stuck when they switched to making graphite pencils
Plot twist: he record the audio with that microphone
I'm gonna use that the next time I play online.
When they ask if my microphone is a tin can, I'll reply "yes, it is a tin can"
(assuming I make my own version that uses a tin can instead of a matchbox)
+Samu Rönkkö Or you can just say, "No, it's a matchbox."
I want to build one of these and then hook it up to a home made cup and magnet speaker. I am trying to push as much as possible through the speaker using a 9v. My question is what kind of transistor should I use?
didn't even talk into it... -_-
Guess someone need to build one and talk into it
Yeah! Don't want to hear "tapping".... Need VOICE example :o(

"Stupid", It Means That It Feels Dumb, Kinda.
Can someone please tell me how does it work??? or on what principle does it work????
and above all does it really work????
As I think, as the little grafite is jumping (vibrating) on top of the other two grafites, this makes the current flowing and stops it too. When it touches the two grafites then the current can flow, when it doesn't touches all the two grafites then there is no connection for the current to flow.
And this current on/off vibration makes the speaker's membran vibrating (because of the speaker's coil's vibrating current->vibrating magnetic field->little peace of magnet or just steel is pulled-pushed), and that makes the air vibrating and that is what we can hear.
look up "carbon microphone"
Tirth Upadhyaya carbon vibration
D O N E
I don't recommend doing this. This IS DANGEROUS. I tried it with two sets of different brands ear phones. Bolth times the ear phones got very hot and made wierd noises even when I was touching them (voice and noise do not work) and one time a spark flew out and hit me.
I don't know if this is just for the materials I used ( a plastic cup instead of a cardboard matchbox, energizer 9V, and cheep head phones because I didn't want to ruin them.)
+Mccrazy that is because of the DC bias in the signal. Just add a 100-1000 uF Capacitor in series with the headphones to AC couple them. Also please check the volume before putting the headphones on your ears, if it is too high, you can add a series resistor, or just put the central graphite piece further away from the leads.
+Marian Keller yup. also 9v DC is waay too much to be pumping into any earphones anyway...
+Mccrazy way to heavy duty a battery for earphones
why do u even use 9V.. wtf
I heard the band "Matchbox Twenty" recorded their 1st album this way.
For anyone wondering, the black microphone in the beginning is a bm-800 condenser microphone.
I only heared it feom the left side of my earphones :D
Yeah you headphones might brake
Little Einstein Where you even listening to what he said? He said it would only come out of one side.
Yes i mea it sticked to it,
Because it could have come out on both my earphons because of recording, sometimes that happens you know
Little Einstein What? I can't even understand you, work no your grammar. How old are you?
11 and im not american so exuse my grammar.
And I ment the thing when your recording it will come out on both of your earphones/speaker

This technique is what the Soviets did back in the 1960's when they built the US Embassy in Moscow, the rebar in the building acted as the lead while the whole building was the match box.

sebianoti But U.S. CZcamsrs do that as well, with NatureBox, Netflix, Hulu+, Audible.com. It's definitely possible that they use these products, but their advertisements make more money for the companies who in turn pay the CZcamsrs as sponsors.
