Magnetic Launcher

[kiryutinaleksey]

Try to take video at least with 60 fps. Put ruler under the ball. Then you can measure position at defferent frames. Ecah frame @60fps has about 15 ms. So you should be able get Position(time), speed(time) and you will get acceleration. Very intresting launcher!!

[EastCoastPeace3]

0:40 four* ?

[Thekidwhofailsalot]

now make this 100x bigger and see what it can do

[dbaioco1]

try lubricate the path the ball goes

[SuperFulltone]

but i think we didnt see the ball going down the rail enough...

[SuperFulltone]

dat is so coul

[ceilingkitteh]

3:03

Screw gravity!

[Xblow23]

You are not right. The ball doesn't have constant speed, it has constant acceleration. So V = 2.14 m/s (and acceleration a=12.12). So the energy must be multiplied by 4.

And WTF the mass is 1.5*10^(-5)? May be you meant it weights 150 g = 1.5^(-2) kg?

But the video is interesting =D

[Emeengor]

@Xblow23 speed is measured by distance divided by the total time needed for this distance or u=x/t were u=speed,x=distance,t=time in S.I u is meters per second (m/s) thus x is in meters and t in seconds.

the total energy Etotal of the ball equals to the sum of its kineric energy K + its dynamic energy U or Etotal=K+U => Etotal=1/2m*u^2+1/2Dx^2 wereD a constand though at the beging of movement speed u=umax and the dynamik energy equals to 0

also this small sphere could be 1.5*10^-5 kgr

[LM632]

lol, I barely understood what he was doing the entire video!

[holycrap989]

i dunno y but this is rly interesting

2. He has way to much time on his hands.

[thajinjaninja]

baby rail gun anyone?

[hiropopon]

1.5*10^-5[kg]=15[mg]

Only 15mg? Is it right?

[4781d36]

You know, you'd be really awesome in Fallout 3!

[TheYO064]

PROTRACTOR FAIL.

[VNluckyboy]

dude! you place the protractor in the wrong way!

[infernalmaster1]

OMG speed calculation!!!! Epic fail!!!!

This is accelerated motion.

You should use instantaneous speed for kinetic energy calculation!!!!!!!11111

It`s look like uniformly accelerated motion.

distance=v0*t+a*t*t/2; v0=0; => a=2d/(t*t);

v=v0+a*t; => v=2d/t=2.15m/s.

[buttholeeat69810]

thumbs up if you though part1 is just as boring as part 2

[SamKennedyStuff]

I don't get it, why does this have 120k+ views, I used to play with magnets when I was 7, why don't I have 100k views? :(

[DomLFM]

SHOOT SOME 1

[araspaulius]

wow we could use it for transportation :D

[Pwnedanime]

@araspaulius pretty much already done but differently. never heard of a maglev train?

[araspaulius]

@Pwnedanime is it in japan?

[Pwnedanime]

@araspaulius its in testing atm throughout the world as a cheaper alternative to conventional rail. But i believe japan and a couple of other countries have atleast 1 functioning maglev monorail.

[araspaulius]

@Pwnedanime yeah I've heard of it.There is a guy on youtube claiming he created a perfect engine(that generates power on its own forever) with magnets check that funny stuff out :)

[Pwnedanime]

@araspaulius You mean a perpetual Motion engine? They only work in "free moving environments where the only thing its driving is itself but would never work as for say moving a car as the energy it produces would be instantly lost in moving it :D. However in space a PME might work!

[araspaulius]

@Pwnedanime Yeah and that dude claims he created it with magnets he said einstein was wrong and e=mc not e=mc2 I dont say he's right but I just thought it was somewhat interesting.

PS:I'm not a retard you dont have to explain what that means I understand it but english is not my first language so I dont use too many fancy words. ;)

[Pwnedanime]

@araspaulius lol well im the retard for putting free moving environments when its SELF CONTAINED ENVIRONMENTS lol!

[Sabewolf]

@araspaulius P.S. its e=mc^2 not e=mc2

[8maxthemax8]

will it blend?

why no make a fucking railgun alredy.

the tech exists. someones too lazy xD

[ashugtiwari]

thats really nice concept man, i like to do it, is there any article on it, you wrote, thanks anyway.

[wolfman5494]

lol i actually knew what the equations at the end were. I might be a crappy physics student, but at least i learned something.

[TheMegaeric]

5:40 -5:48 in english please

[XSazuke]

@TheMegaeric lol,go to school :P

[TheMegaeric]

@XSazuke they wont show u that at school if your 9 years old ._.

[TheMegaeric]

@XSazuke BUURRNNN!!!

[ParcourManiac]

@TheMegaeric what he means is that speed is equal to the distance traveled over the the time taken so if the ball went however far it went in the time it traveled the distance in (.19 meters divided by .177 seconds) that means the ball was going at 1.07 meters per second

[TheMegaeric]

@ParcourManiac aha... english

[ParcourManiac]

@TheMegaeric the kinetic energy part I havn't a clue

[Sortamm]

jimbo6797: you've measured the angle of the launcher wrong

Speed and energy also measured wrong. This way your'e got just mean value of the speed, but for kinetic energy math you should use max speed of the ball reached at the very end. Your calculated energy roughly twice lower than actual.

These rough errors are very strange for the man associated with university. Let me guess... Are you the university janitor?

[VaneLetsPlay]

isn't it the same system like on some rollercoasters?

[FalklandsFinest]

Nice flatscreen.

[wangahsan]

haaaaaaaaaaaaaa hmmmmmmmmmmm thap thap sleepy

[MadGamer7654]

I WAS LIKE YEAH AT THE FLINGER THING !!!!!

BUT THEN U BROUGHT UP ALL THE EQUATIONS AND SHIT AND I WAS LIKE DUH???

[unknownazn6]

possible for you to make an video on how to make one of these with the materials used?

thanks in advance.

[Paool3107]

Sorry if this sounds stupid, but how are the cube magnets on the side not sticking to each other?

[audhen1]

@Paool3107

They are glued by "hot glue" - don't know if this is the right term :)

[moshimonster33]

@gillbondfac how much is the magnet?

[Ezazael]

If you turn that into a gun, make sure you always know witch end is the front, or you'll get one hell of a shiner

[Chik0r0]

How does it work?

[TheRecklessVoice]

This shit's fuckin' gay. Where's the fuckin' gun powder?!

[dk0bl1v10n]

this tecnology is already used in those trains moved by magnetic forces...

[TheTutorRodrigo]

I liked the part that he showed his balls :)

[YHSAlink]

Very nice.



[FlipJick]

This would be incredibly useful if we ever start a war against a nation of credit cards.

@FlipJick You mean the human nation?

@FlipJick low IQ simpleton

[FlipJick]

@mysql0 Was my joke not up to snuff? Do you feel smarter now that you've insulted someone on the internet?

[mysql0]

@FlipJick I wasn't responding to your joke...

I was responding to your logically flawed and incorrect comment trying to imply that this invention is useless.

Simply because all you see is a ball hitting a credit card on this video, your low IQ simpleton brain cannot fathom it being used for anything else, hence your bad joke: "This would be incredibly useful if we ever start a war against a nation of credit cards."

It was too re-tarded too respond in depth, hence why I just said "low IQ simp

[JereMedia01]

@mysql0 "I wasn't responding to your joke...

I was responding to your logically flawed and incorrect comment trying to imply that this invention is useless."

Oh, you mean his joke?

[Armourix]

@FlipJick using this magnetic design you can generate massive amounts of energy with little cost it appears. more use than smacking a credit card.

[qayghjkedc]

hey fuckhead. magnetic "energy" is not gravity.

[dadvoc666]

good you really know how to measure the angle of an inclined plane... :D :D :D

[PabloManUK]

what happens if you make your launcher 1 meter long?

would it increase the velocity or is there a limit to the speed?

[magneticpower1]

How are the magnets aligned? Are the poles on the end or do they face up?

[partho00]

Hey I have a question. Would it be possible to make a circular design so that instead of the ball stopping at the end it would continuously keep going round? Could you think attach some form of electrical generator to it to provide electricity untill the magnets eventually lost their power?

[Xirithrenegade]

@partho00 That's only possible if your using a generator to activate and deactivate magnets periodically, so it goes in a circle, otherwise it will go to where the magnetic force is the strongest and stay there (unless the force is the same from to different areas, in which case the magnet will be stuck directly in between)

[Volorick]

how is that cool....thats like the most boring science homework ever!!!! you call it a launcher it doesnt i even launch the ball!!! make it break a drinking glass add a little spice to it haha

[inner101aggression]

a cool friend of mine with a weird smile once told me that the perfect way to get rid of a body is to feed the victim (before you kill him/her) a lotta spinach.... go find a lake, throw a big magnet in the lake, then throw the body, it will stay on the bottom, untill it will be tottaly decomposed

[bugijs123]

dose it has to stop at the end?

[bugijs123]

cant you make it in circle?

it would go for ever

[Hatchatfatbat]

@bugijs123 Not possible to make it go forever, try yourself! If you make that happen you are able to produce infinate energy, so its litteraly breaking the laws of physics.

[WhomTheGodsDetest]

@Hatchatfatbat and you just broke the laws of English.

[needusername12]

@Hatchatfatbat Haha I was going to say that. If you find out how, you will have solved the worlds energy problem.

[Spirou4D]

Architecte, j'y vois une application concrète. J'ai rencontré un designer qui cherchait un moteur longiligne comme le rail du train magnétique prototype français. Il cherchait à remplacer le moteur rotatif des portes de garage par un rail longiligne comme le votre....

A suivre!

[splinti]

afaik 1,07*3,6=3,86 its a small distance dont forget

[WoLF2Own]

only 3.86 km/h? or did i do something wrong...

[The4bdog1]

say if you were to make a complete circle of this track, would the ball travel at that speed around it, infinitely? a perpetual motion device?

[masterchief133742]

@The4bdog1 no, this only works because the magnetic ball is pointed to the strongest magnet.

in a circle the ball would direct move to this magnet(even by leaving the track set up with this U formed pipes). and stay there.

If there is nothing like a strongest magnet the forces of all the little magnets forming the ring would eleminate each othher.

so sadly this doesnt work

[needusername12]

@The4bdog1 Nooo thats impossible. All it is ( i assume ) is a track of magnets that are growing in strength. So it would always be dragged to and stop on the strongest magnet.

[astigide24]

not actually a launcher

[zacpwnr]

Does it blend?

[aBlindMoron]

BUT.

Does it shoot stuff?

[acountfree]

You used your protractor wrong, you measure angles from the center of the device to the outside ring, in the video you measured from one side to the other. To verify you are using the protractor correctly, the angle of the surface you are measuring should pass through the very center of the protractor, with the 0 degrees parallel to a reference point.

[JohnDefy]

does mormons know this weapon exists?!

[mrmivpushkin]

Can you link a tutorial to this?

[effinTRAITOR]

Basically it's a non-electric Gauss gun.

[Lavidrocks]

Just to let you people know, the ball was only going an average of 3.88 km/h so... not that fast. Then again he doesn't have a very long track. The ball may go faster with a longer track. Someone try it and tell me you're results, I would appreciate it. Thank you.

[scundie1]

a new toy for toddlers



[x0u]

the turning point of the launcher has to be against the middle of that circle



[jimbo6797]

you've measured the angle of the launcher wrong.



[tyh0304]

@jimbo6797 not only d angle but the units of grams is wrong too..but its okay if he is not a science researcher..

[modwebby]

@jimbo6797 indeed, probely never learned geometry

[megakiller999]

COAT THAT IN TEFLON!!!!

[MrPKenneally]

is it possible to detach the last magnet that brings the sphere to a stop, thus a;;pwing it to fly off?

[megakiller999]

@MrPKenneally No because then it would just stick on the one before that.

[hi612345]

F5 to skip adds

[ed0411]

most of the time on this test is wasting our time LOL

[kd8894]

im sure its an obvious answer but whats the point of the glass of water??...whats its purpose??

[zalovitch]

@kd8894 I think that the purpose of the glass is to show that there's no trick with camera and table angle and that they are set horizontally

[EVpowered]

What if you fire off the first ball and it stops at the top, then you fire off another ball behind it would it launch the first ball?

[crappymeal]

@EVpowered i would like to se this

[QuintusSecundus]

Are those the same cubic magnets used in hard drives? When I opened my old one I found some relatively strong cubic magnets in there. So one could build a small railgun out of several old hard drives?

[megakiller999]

technically this is a rail gun except a rail gun fires the magnetic projectile instead of using it to hit something else.

[zyriuz2]

have you ever tried to make a longer and better launcer, cuz it would be cool if you could make the ball go through things like apples, cans, yeah random stuff ^^

[John88LC]

That protractor was positioned completely incorrectly for measuring the angle of the ramp in case no one noticed.

[shredthegnarbrah]

@John88LC I concur.

[Millenium255]

2:08 > Ha Ha.

[ty1a2t]

what is the cup of water for?????

[riometal82]

wow... you can build alight gun with this. it will be a good thing to make a new kind of soft-air gun :D

[Marcraft22]

Awesome work. Could it be used to be a weapon?

[pongasunombreaqui]

almost 4 km/h?

[Jayshrewla]

how much will u sell them for

[gilbondfac]

@Jayshrewla 1 million dollar... pfff... No it's FREE you could build it many students have build it in my universty

[SuperFREEXBOXLIVECOD]

@gilbondfac I'll give you 2 thousand, THAT'S AS HIGH AS I'M GOING

[Z4RUM4N]

@gilbondfac @Jayshrewla you could still probably sell them to people to stupid or lazy to build them for themselves, might be able to make some decent money.

[TheEpicFailMaster]

@gilbondfac are there intructions on how to make this :)

[gilbondfac]

@TheEpicFailMaster yes look at my channel you found video of the kit of mini launcher

[dylandionrakiman]

@gilbondfac one million dollars *puts pinky in mouth with a smile* :)__

[enoctis]

does the ball HAVE to be magnetic?

[gilbondfac]

@enoctis yes it's a magnet ball

[enoctis]

@gilbondfac i think there's a language barrier here.. what I meant was:

Is it required for the ball to be magnetized or will a steel ball work?

[The3rdPlateau]

@gilbondfac presumably the projective doesn't though...or at least not the rubbery-lookin one. i dunno about the metallic one, but wouldn't that be more efficient if it weren't?

[theSpaceChimp]

@enoctis This might be the most stupid question I've ever heard.

[enoctis]

@theSpaceChimp wtf are you talking about?

[valtex5]

@enoctis clever, think a bit

[lance2466]

why wont you fuckin launch something you fagot?

[enoctis]

@lance2466 you're pathetic

[fartfacecurry]

i am so lost right now

[Zacq768]

wtf am i watching

[sulfuricSHAME]

where did you get the neodymium magnets?

[gilbondfac]

@sulfuricSHAME link to supermagnet.de

[AmishSpaceNavy1]

Now to get it to not stick at the top but roll off...

[EtaZuper]

I am not 100% sure how this is set-up but, is it possible to make a circular mechanism similar to this on where the ball will travel endlessly.

[kapialex]

can you send me the plans pls

[kapialex]

can someone send me a construction pls

[kapialex]

can someone send me a construction and the materials wich i need pls on this mail kapialex@web.de

[mkgecko]

Can anyone answer these questions? 1. Are all of the magnets pointing N on both sides of the ramp? 2. or is one side a row of N and the other a row of S? 3. Why doesn't the magnet ball just stick to the first magnet pair? 4. From other videos it looks like the main thing is to build bigger stacks of magnets as you progress along the ramp. Is there a limit to the final speed that you can get? 5. Does the ball magnet slide (more friction) or roll (less friction)?

[gilbondfac]

send me your email for the files !

you made an error of 10-3 for the value of Ek.

it's 1.5 10-2 not 10-5

[CWSSje]

hello, i am rather inexperienced in this field but i would like to ask if you have considered using increasingly stronger magnets to accelerate the ball bearing. Thank you

[EnjoyEnergy]

Hi Charles, please if possible could check the following:

1. Neodymium magnetic throw a ball on the ramp.

2. Place a piece of wood before the ball braking.

3. Lanazas other magnetic ball.

¿¿Does the second ball would bring down the first ....???

THANKS

I wonder, how much "payload" (say, balls of wood) could the steel ball drag along up the ramp? If it's a significant amount, being more than the weight of the steel ball, that would be most interesting.

I don't know anything about magnetic fields, but if there is OU somewhere, I will find a way to engineer a setup that will loop it. 13% as Naudin's SMOT was found to offer, at a nett 34% loss, that's a great start, but there may be setups with great efficiency out there.
