DIY Make a speaker

[WiggaMachiavelli]

Does the direction of the current through the coil affect the sound? I mean, you get a force and sound either way, but it's the changes of direction that actually matter, right? So if compressions and decompressions are swapped around by running the current the other way, the sound is not going to wind up being distinguishably different, is it? Or am I making a mistake here?

[Starcross42]

@WiggaMachiavelli No. You have it right! I was going to tell you that by reversing the polarity the sound would be backwards, but that would be just silly.

[TheSupertecnology]

wtf, your speaker wasn´t working at 3:34, it was the real music, because it was stereo, not mono, and it hears very good to be your speaker. sorry, no insult, just aclaration.

[Starcross42]

@TheSupertecnology I actually said that I 'dubbed' the music because of the poor recording quality combined with the speaker. This is not a HIGH QUALITY speaker... just a proof of concept.

[alexisoviedo100]

if i were to do this same thing but connect a pair of headphones, with the ear buds cut off, how would i connect the coiled wire on the cup to the headphones?

[Starcross42]

@alexisoviedo100 Earbuds are designed to be very small. Probably would not work the same. Sorry.

[JacobSijsma]

Now make a gauss gun...

[MrNikhilking]

That how to plug it to speaker mines is 8vlt and idk how to set the batterie

[Starcross42]

@MrNikhilking I don't know what an 8V speaker is? What are you trying to do with the speaker?

[MultiMinecraft123]

@MrNikhilking um i think he means 8 watt speaker

[Starcross42]

@MultiMinecraft123 Or 8 ohms seems right for a speaker.

[MrNikhilking]

How did u set that other speaker ??

[Starcross42]

@MrNikhilking What do you want to know?

[Rockflier]

Nice vid but "I push it back down and it comes back up"

[hitachi088]

i am surprise that our body is not affected by magnetic field .

[WoofusDoofusKid]

Thank you for taking your time to record this video, Incredible information, great stuff. Thumbs up. I will even lead my friends to watch this. Great description, and you did wonderful at describing everything, and how everything actually works. Thanks!

[Tinuserviceline]

somebody has to say it: fucking magnets

[starmanbarber12345]

i alredy know that wire and magnet makes electricity, but thank you for some boaring ass school shit though

[WoofusDoofusKid]

@starmanbarber12345 "Thank you for some boaring (note: Boaring) ass school s*** though", First of all, you shouldn't waste your time clicking this video and actually 'WATCHING' the whole 8 minutes of it, just to post a comment on how "you already know that a wire and a magnet make electricity", if you already knew, then why watch it and continue to watch it and then post a useless comment that takes up space? Oh by the way, The video is great, Good instructional / Education video, Starcross.

[mohammedowais1000]

its not to good dont like it but i wana more experiments 4 my expo pls any one can help me

[Qkumber1]

Just add double a

[asprin4themasses]

Thanks for video what are those spinning tops actually called?

[CharlestonChew03]

Very educational! Awesome video.

[windoes98se]

you should hook asn amplifier to youre home made speeker

[infiniterealitiesOrg]

thank you! this is a very informative video!^^ thank you for sharing!

[alco19357]

this is really good

[Starcross42]

Thanks.

[frosty1433]

@Starcross42 are you ready for this? theory: gravity is nothing more than a very complicated magnet. am I right?

well it that's right, we could match the earth's magnetic field and achieve levitation.

[Starcross42]

@frosty1433 Actually, gravity is quite different than magnetism. Sorry. Actually Einstein spent his whole life thinking about gravity and was not quite able to fit it into the big picture. It is weird stuff. But yes, if we had an antigravity then we would have levitation.

[frosty1433]

@Starcross42 I still believe there's gotta be something to that theory though, or else why would higher quality magnets "have a tendency to be heavier?"

when I thought up that theory, I sort of imagined billions of tiny atoms, each having their own positive/negative poles which were all somehow how pointing different ways. what if an atom has multiple positive/negative poles surrounding it? it would be like having billions of atom sized magnets all pushing and pulling and effecting each other.

[frosty1433]

@Starcross42 if gravity were simply just a giant complicate elaborate network of tiny atom sized magnets, wouldn't that explain why we would even be able to lift an actual magnet off the ground? of course to understand that, you would have to assume that gravity was just magnetism.

I really need to go to school for this lol

[frosty1433]

@Starcross42 btw, higher quality magnets being much heavier supports my theory

[Pre1239]

NICE !!!!

[MajorUtah]

Man.. you rock

[Starcross42]

Thank you so much for revealing this important fact. I have thought that people did care, but now I know the truth. Thank you so much for sharing your insight.

[CINDYSHEEHANWASRIGHT]

Bring Back Chelsea!:)

[invertedbeardthe2nd]

Great toys. I was watching a documentary the other day about Nikola Tesla. I wonder if he would of appreciated these toys. Cool!

[Starcross42]

Actually, Tesla wanted everybody to get free electricity this way. Government projects the energy and people have coils of wire in their houses to turn it into usuable energy...

[STOPnTHINK]

telsa had the 1st remote controlled car via radio waves due to his oscilliator.... He actually had those `toys`set to a practical use that make millions in sales today!... anyways i was just stating on ur , if he would of appreciated ( duhh he invented it ) these toys .) Tk and solong

[sciencewiz600]

Sweet. Where can I get one of those 'top toys'?

[laserguy42]

Very nice. I like the music too. Oh, and your 'bonus features' at the end were funny.
