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!
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.

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...

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.

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
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 UA-cam also. Good luck with your project!
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.
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?
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.
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.
Graphite leads are good conductor of electricity, don't you think there will be short circuit when you complete all connections? Is it really way to make microphone?
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.
Hey thats just awsom i tried it and it was the 1st project that was successout of all of the videos i watch it works but you cant talk to it since the grafite on the top should move to make a sound so if you need to talk it should be moved acording the waves produced by your voice .
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.
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?
@@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?
@@FUNNY_CHESS_SHORTS yes, it did ! but as far as i remember, there's only a faint sound when i'm tapping the leads but cannot actually speak with it ⭐️
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.
you can get the same sound even without connecting the lead just directly connect the speaker to battery and just scrub the wire on any end of battery same sound will be produce ,here in this video the lead are just acting as contact and as i said scrub the wire on battery the same thing is happening here by tapping the MB , am i right Dave :)
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)
Can you use the same wire with 2 microphones and 2 speakers? I know, you will hear yourself, but I think it could work! You would need to use headphones so it doesn't create a loop and start making a high pitched sound!
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.
because he said that, are you now obligated to buy those headphones? no, yeah i dont think so. whats not cool about making some money? he still made a cool video
sebianoti But U.S. UA-camrs 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 UA-camrs as sponsors.
