[archanqel666]

ratio of leghts and mass, please.

[Softeyes1]

Can you connect a turbine to this to make renewable energy?

[sphinx245]

Reminds me of an iCarly episode. Im not sure if i should be ashamed by that...

[normallyjunk]

is this random, or is there an actual algorithm going on here....?

[Diggydiggyholeful]

I wonder how many hammers it takes to make it fall over...

[Something2look4ward2]

Not exactly perpetual I presume, as to be expected, but really close. I'm impressed.

[rocker6219]

how do you start it

[kenkineticart]

@rocker6219

Start it by giving it a push. See "Waltzing Hammers"

[edzen07]

cool. infinite energy.

[springhill1958]

The next one you do can be called "Hosea's Hundred Hammers"

[MrJohnDevour]

the backdrop is moving a lot, I suspect someone is using airflow to influence the device and make it seem to move more or longer than it would on it's own...

[kenkineticart]

@MrJohnDevour

I wish that were the case. I'd like to be able to get these things to move in a breeze but they don't. The reason it moves at nearly a constant speed is due to the inertia stored in the hammers and the low friction of high quality ball bearings mounted in perfectly aligned hubs. No tricks.

See "Waltzing Hammers" for more information about how they work.

[EyesFat]

@MrJohnDevour lack of science knowledge fail

[Anonymous01959]

@MrJohnDevour you may have a point but the counter weight is a sledge hammer. Wouldn't they a stronger airflow than indicated by the back cloth?

[rammbostein]

All in all you 're just another brick in the WALL

[futsalfred2]

does it need batteries

[kenkineticart]

@futsalfred2

No batteries, it runs on inertia.

[juicebox232]

ok now who watched the whole thing ??? i know i did

[ThePrickStick]

If you connect the bottom hammer to a pump that will be infinite energy :O

[Aviatorsmith]

@ThePrickStick No.

[pHappyfeet]

i made something like this in Little Big Planet.

[MrTestosteroneboy]

Any tutorial on how to make this hammer?

Like materials used, how to make it, etc...

[kenkineticart]

@MrTestosteroneboy

You can watch me build a set by viewing "Making Waltzing Hammers". I have no instructions or plans available.

[StarDestroyer5]

this is so cool!!!!!!!

[saint7412369]

So many degrees of freedom..

[demonhand]

I heard you liked hammers so...

[xpez]

Put this in a car..."My car runs on Thors hammer's"

[12TreaL11]

is this also same as what i have seen in Iron Man 2?

[Seelenfeuer666]

I want this on the next funfair! =D

[rickreed123]

That would make a puke-a-licious carnival ride.

[gnowave]

it is very beautiful.

[RoboticusMusic]

GAYEST MACHINE EVER XD

[Gafaton]

@RoboticusMusic You misspelled troll.

[RoboticusMusic]

@Gafaton what? a Troll hammer? Fucking Nerd.

[wthrfish]

Is the time it takes to stop after a certain amount of initial energy constant?

[AndreasFalk8]

yo dawg, i heard you like hammers, so i put a hammer in your hammer so you can look at hammer while you look at hammers

[Theonegamefreak]

Dude, this could work as a ride at some park or something.

or a clock. That'd be so cool.

[Texmurphy51]

A variation on the old 1960s Mobile.

Neat twist on the idea.

[Lotum4n]

What is the calculation you used for each hammer where the pin is located approximatly ?

1/8th the weight of the hammer ?

Im just curious .

: Tim

[kenkineticart]

@Lotum4n I don't locate the balance points mathematically I use a tool I developed to find the points. There are too many strange shapes and variables to do it accurately with math. So no formula is used, they just are where they are.

[honorific88]

@kenkineticart "There are too many strange shapes and variables to do it accurately with math."

You sir, are obviously not a physicist. But skilled nonetheless.

[Idiomatick]

@Lotum4n The mass on each end of each arm is balanced which is why they spin freely. The last arm has the hammers at an even distance from the pin so the hammers are the same weight. This arm with hammers is slightly heavier than the next hammer so the pin is closer to the final arm... and so on. The specific ratios used should not effect how freely the system moves. Higher ratios will make the system more eccentric though.

[CreeperSsssMC]

woah

[56tony1]

How very cool... Nice choice of materials...Could tell the way it was running you must have used bearings... Bet finding the exact balance points took a while... Very cool piece !!!

[anduschatz]

Makes you wonder if someone could make an amusement park ride out of this. ;-)

[8element]

yo dawng, I heard you like hammers

[Oshyrath]

When I was looking at this, I was like O:

[Duraltia]

Hmm... "Hammer Time!" xD

[basantologist]

I can watch this all day o.O

[leatherfacefan1974]

It just some spinning ha- ALL GLORY TO THE HYPNOHAMMERS

[megamaa]

Add some LEDs

[CatsRuleDogsAreTards]

Still reminded of the thing on Pepper's desk in Iron Man 2.

[megamaa]

@CatsRuleDogsAreTards :D

[N0tsaved]

Why am I laughing my ass off at this? xD

[therealbasskiller]

very cool!!

[The21Area]

wtf is this soo interesting?

[iloverikku714]

will this ever stop?

[bigclivedotcom]

Very nice. A battery operated magnetic kicker would be nice to keep it running continually. The simplest kickers used in the olde-style perpetual motion ornaments just used two windings on a steel core and a single transistor. There was a heavy winding to provide the kick and a finer winding to trigger the transistor when the pendulums magnet approached. When the transistor started energising the kick coil it also provided positive feedback to the trigger coil to give a good meaty pulse.

[sacr3]

Funny, There is no such thing as "perpetual energy" yet out universe runs off it. Them particles just keep spinning, no stopping to be seen. yet at our level we cannot harness this.. too much energy loss, friction, heat, etc... oh well.

[073468magnuM]

this is godly.

[MrRespect26]

where can i buy this i really want one

[kenkineticart]

@MrRespect26

To purchase you can contact me by visiting my KenKinetic website.

[sakiLOVER]

@MrRespect26 all you have to do is buy a sledgehammer, 4 metal work hammers each 1 size smaller than the other, 5 nice quality skateboard bearings a stand for the main sledgehammer and then you just need a drill and a rubber mallet and a lil time ;]

[kenkineticart]

@sakiLOVER

Try it, you'll be surprised.

[XDlizzXD]

you lost the game TROLOLOL

[CatsRuleDogsAreTards]

Why am i reminded of the thing on pepper's desk in Iron man 2?

[Pavilion755]

I dont get it ._.

[Canadan20]

they could make an amusement park ride out of that... complete with chunderbags...

[SpazzyMcGee1337]

Looks more like Loki's hammer.

[PowerHouseNet]

its soooo trippppyy!!!

[rockoman100]

IIII WAANNT ONE

[draccanon]

paint it to look like the hammers from the wall... i would buy the crap out of it :P

[kenkineticart]

@draccanon That can be done! Go to my website to contact me by email and I will make arrangements to get them built and sent to you. Ken

[FireflyIsland]

@kenkineticart do you deliver in holland? :P

[kenkineticart]

@FireflyIsland I've delivered to Mexico and England, I'm sure I could deliver to Holland.

Ken

[Vlad3000]

hypnotic. Thanks.

[yii1990]

Is this chaotic dynamic ?

[rvbman47]

@yii1990 dynamic

[iLaseFMA]

In our technical college we built a box with magnets on the ground which let a spinner hover in the middle.

We spinned it by hand and then we closed the box and evacuated it

with a strong vacuum pump.

The spinner spins for 3 days til now ;-)

[sabritas182]

wooow that little is pretty cool lol

[kiemul136]

Does it stop eventually?

[kenkineticart]

@kiemul136

Yes it does. Its slowing is imperceptible as you watch it but in about ten or twelve minutes it will come to a stop.

[Computergeew]

@kiemul136 It has to stop, as there can be no such thing as infinite power; everything needs a source of energy (but rocks :P)

[rochelimit55555]

I can see this kinetic art forever

[acylon1]

This is so cool. I would really like to build one. I have some questions about it though.

It appears the main large hammer is balanced so that the peen stays down.

Are the rest of them balanced like that too? or just equal balance from pivot point?

[kenkineticart]

@acylon1 ...Only the sledge hammer is purposely off balance. All other hammers are balanced as closely as I can get them to neutral.

Ken

[NigelLoller]

I bet that took some time to balance up!!!

[deaftodd]

Pretty cool, it reminds me of those zipper rides at the county fair.

[socue521]

 nice :D

[lestersole]

So epic I jizzed myself.

Great mind you've got there, bro.

[Dawid4Real]

i love it

[kenkineticart]

Thanks for your comment. This system of balanced hammers was fun to conceive, construct and show. It, along with my other kinetic scullptures have given me an opportunity to use art to teach the basic consepts of mechanical energy to the general public.

[lekunberriko1]

very clever device!

[Truesader]

awsome

[CalicoatMaker]

I've been working on something that can harness energy from this, but anything I do to it loses energy in friction or other resistance. Using a double pend. Tried a triple but it often drags the entire device to a halt when there are two opposing forces on an axis against gravity.

[kenkineticart]

My hammer system does appear to be perpetual motion but as with all mechanical systems, it is not.

It is operating with the initial energy that I put into it with a push just before starting the video.

I use precision bearings and hubs to minimize friction loss but over time the system will slow down.

Any attempt to harness this energy (remove it from the system to use elswhere) will quickly drain the initial energy and, as you found, drag the device to a halt.

[beaudjangles]

energy in equals energy out, don't be fooled into thinking that there is more energy in this device because of movement.

[shadowman080]

there is not such thing as perpetual energy thermodynamics proves this

[Techstuf]

@shadowman080....We are all made of atoms with electrons spinning about them at great speed. I don't know how they got started spinning, and I don't know how to stop them, do you?

[devjock]

Is that a pendulum in your pocket, or are you just happy to ...

Oh wow, really nice pendulum. Great theme, nice color scheme, nice!

[PaulNaoki]

wow!!!

[plamboline]

awesome!!

[jstarret]

Great work!
