Dumbbell Cube

[OnceUponAJon]

This looks impossible O.O

Would I be correct in assuming that to solve both cubes, you would need to reorient the cubes back into their original states (including the rotational orientation of the center squares), rendering common rubiks algorithms useless?

[OskarPuzzle]

@OnceUponAJon Yes and no. You can still use common Rubik's Algorithms, but you need to apply them cleverly.

[8Flamedog8]

some good lubricant will make this puzzle even better

[OskarPuzzle]

@8Flamedog8 This puzzle is well lubricated with silicone spray. Without lubrication, it would be completely stuck.

[areezzy]

These puzzles are hilarious! I'm not a person who would buy these things but I enjoyed a lot watching all these weird shapes. I don't know why some people would make negative comments about your designs or construction (in all your other videos). I'd understand if they're complaining after spending too much money to purchase a defective item, but otherwise they should shut up and move on to other YouTube videos. I think these inventions are great. Blijf uitvinden van nieuwe kubussen, Oskar!

[d4m4s74]

if you solve one of the cube, do you automatically solve the other one, or am I mistaken?

[DackxJaniels]

Haha, I love the ever so faithful "thank you for watching" at the end of your videos!

[gelman912]

This is by far your best puzzle ever

[GiorgioCapocasa]

So beautiful!

[BrendanChaplain]

The dumbbell cube...not meant for dumbbells

[4Grubbies]

way cool

[ExoVampire]

I would just use it as a hand weight in gyms!

[4Grubbies]

awesome!!!!!!!!

:) :) I want to buy it

[tigerboy1227]

this would be perfect for tutorial videos.

[cvaughn55]

i would buy if i had they money

[ben1996123]

if one cube is solved the other isnt automatically solved.

think what would happen if you did R L R' L' on one of the cubes.

[mike1992123]

This is my favorite puzzle of yours. Sadly, beyond the Over The Top cube, it is also the most expensive. Is it the gearing system that causes the price because it uses more material?

[OskarPuzzle]

@mike1992123 Correct. Not only is the outer volume about 3x that of my usual puzzles. Also the inner space is almost solidly filled with gears.

[CSmodder]

@OskarPuzzle nice idea i think this is good for teamsolving ^_^

[acdcfreakNr1]

can you solve it?

[youdougit]

your best puzzle yet. Good job man!

[raydog97]

You are a true artist and genius

[OskarPuzzle]

@raydog97 Thank you!

[xyzpdq75]

wow



[b00b3rrymuff1n]

Can you get parity or something? Maybe if one cube was solved and the other wasn't.

[jonaspoffyn]

who would buy that? for that prize you can get a life to

[Vojife]

Wait. Doesn't solving one of the cubes solve the other one?

[OskarPuzzle]

@Vojife No. They are not mirror images.

[WildChik45]

@OskarPuzzle

You say it like we should know

Epic dude

[InsideOrionsBelt]

I've said the same thing watching all of your videos... What the crap!? lol.

Good work on all your puzzles!

[KKOBII]

I don't understand. If every single move you do is mirrored in the other cube, what makes it having twice as many combinations? From the video, it seems as if you scrambled it up, the other cube would be equally as scrambled with the same combination of moves, so if you focused on solving only 1 of the cubes, the other one would also be solved since all moves you do are mirrored in the other one. Am I missing something? If so, can someone explain this?

[adnh311]

@KKOBII Wrong. From watching closely you will see that some of the sides turn normally and some of the moves are mirrored. Yes, tricky indeed.

[gregslife7]

I don't get why would this be hard. Wouldn't the two cubes be exact duplicates of each other, if all the sides are coupled?

[gottagetthatkill123]

why is this guy alive?

[RaymiHennessey]

would it be possible to connect 3 cubes in this way?

i ask because i enjoy the idea of a rubik's cube cubed.

[OskarPuzzle]

@RaymiHennessey Yes, that would be possible. If you order two Dumbbell Cube sets, you would have enough parts to build 3 connected cubes in the way that you describe. Note that the 3 cubes should be in a straight line, because of the handedness of the gears inside.

[Area51DnB]

haha ure so funny

[beeneyluke]

this guy has something wrong with him

[makkonen28]

why you do theese cubes and put 500 dollars in every cube i think one of the ten million buys it

[holcickany]

people invent so much sh*t, they rather spare their energy on curing cancer

[LucasMueler]

@holcickany I don't see how a rubik cube designer could cure cancer.

[genevivewoods]

i oove the way you say "thank you for watching" haha the other video, also the same tone.. XD

[larie2]

I used to be able to make things as cool as this, but then I took an arrow to the knee... I'm sorry I just couldn't resist! =P

[urijustin]

next time dont advertise something if it doesnt work right.

[TheMrcobain]

@urijustin and it doesn't work how?

[shaunbusby]

but will it blend?

[Zheige]

great puzzle inventor ever !!

[StonerSnowboarder]

@IgnosticAnarchist yeh it would only be one-to-one if the colors were all located on their same relative sides when solved, very nice, either way

[Aaronferrer22]

watching cube videos XD

[FlippingSpat]

so in other words, by using the same algorithms to solve one rubiks cube, you get the satisfaction of solve two? Regardless of how you mess it up, the second one will be a mirror image therefore solving one automatically solves the other.

[atmhso]

Have you ever tried mixing it up?

[OskarPuzzle]

@atmhso Yes. And world champion Wei-Hwa Huang managed to solve it again.

[mycowthedog]

Alright this isn't one-to-one mapping. Here's why, it's sure close but the one cube on one side is Original as in the opposing colors is Yellow-white, orange-red, blue-green etc., but the other cube is Yellow-Blue, Orange-Green, White-Blue. Now with the different side rotational system adds more scrambles. Your welcome Oskar, love your work ignore that "Haters"

[acasnn]

The amazing thing about your puzzles is that i can see that you are genuinly proud about them, and that makes them so much better. They are all very creative and if i could afford it, i would own all of them. (i do understand your reasons as to why they are the price they are, ;) but that doesnt make it easier for me to afford)

[thisisnotjustin12]

i want one

[1967avl]

The mechanism is amazing!

[loonatic323]

I'm colour blind so telling me what the colours are only makes me doubt you

[SarahHolmgren]

@loonatic323 Let's make it two colour blinds.

[OskarPuzzle]

@IgnosticAnarchist Incorrect, there is no such one-to-one mapping.

[Watcher6637]

@OskarPuzzle but why is the puzzle so expensive i mean 575 dollars is very much i wanted to buy it cause its a very cool puzzle i cube for my life but yes why is the price so high ? Please give me an answer (SORRY for bad english im from germany)

[OskarPuzzle]

@Watcher6637 If you really want to know, you may want to check out the description with this video and with my YouTube channel. I am showing one-of-a-kind prototypes, not mass-produced puzzles.

[MrSailing101]

@OskarPuzzle indeed, because the faces turn at the same time, in different directions

[slainender]

make them heavy and let them all to try like a dumbbell

[DjGrimmace]

i used to solve rubex cubes,but then....i didnt like em anymore :S

[JSasRays]

wow. amazing mechanism inside

[instantnoodler1]

stupid

[blanknot]

I would buy a number of your puzzles, but they're way to expensive.

[MrTshirtboooy]

I have it, I can't lift it:(

[legotechnic27]

Echt super vet ga zo door

[leedsrhinos3201]

stupid, it is just a 2 rubik's cubes

[GreenArt4]

@leedsrhinos3201 nothing like 2 rubiks cubes

[MrEdLoop]

@leedsrhinos3201 Really? Put two Rubik's Cubes on a table. Good. Now turn one. Did anything happen to the other? No? Want to know why not? Because they're two separate fucking Rubik's Cubes, that's why.

The Dumbbell Cube is two connected Rubik's Cubes, thus making it inherently different.

[AsbjornOlling]

That's sick!

I'd love to take a peek inside that twisted mind of yours..

[laugh0at0you]

oshi thats kinda cool

[AminamHD]

Is het niet zo dat beide kubussen automatisch hetzelfe geschud worden? Omdat je dezelfde kant bij beide kubussen draait, dus als je 1 kubus oplost de tweede dan ook automatisch is opgelost?

[IncuManiac696]

Damn, I didn't notice... the cubes stickers... one has the standard Rubik's pattern and the other has the Japanese pattern

[coaster1235]

So. When do we get a Dumbbell Megaminx? Dumbbell FTO? Dumbbell Megaminx - Helicopter Cube (FTRD)? Dumbbell Crazy Circle Cube? Dumbbell Starminx? Dumbbell 5*5*5 - Megaminx? Dumbbell [anything]? Just food for thought :D

[zamkam]

I don't see how the total number of states for the pair is the product of the number of states for each cube. That would be obvious if each cube moved independently of the other one, but that's not the case here. So the question is: For any (valid) state of a 3x3x3, is it possible to get one of the cubes in that state and the other one unscrambled?

[OskarPuzzle]

@zamkam Yes. That is, in 50% of those.

[RandomUserName63]

Ik begrijp waarom je puzzles zo duur zijn, maar dat neemt niet weg dat ze te duur zijn voor mij, jammer, deze puzzle ziet er echt uit als een zeer interessante uitdaging!

[blindbiker22]

@OskarPuzzle That was what I thought...I should have read the description though,One cool thing would be to mass prodduce all of your puzzles and then make your handmade prototypes and models worth more

[JRIZZOBIZZO]

O_O

[MrSkatingman44]

wow

[Cinos32]

@RussianWhiteBoi i even thought so

[Dearhunter43]

Stronger and Smarter.

[LewisAM37]

this looks impossibly difficult to solve

[AznAndy562]

man i want to see u finish each one u have x.x

[Minecraftifi]

I jizzed myself when i saw this!

[mrhugoty]

How about the M Face ? The color scheme of the other cube is really wrong, well the M Move works ?

[1slave25]

@mrhugoty

that "wrong" scheme is what makes it harder.

[ohiocuber]

He said "Dump Bell Cube." lol.

[TehAwesomishdude]

Ech waar joh?

[OskarPuzzle]

@RussianWhiteBoi No.

[LunaBiancci]

Wow... just, wow.

[RJA10001]

but it'd solve just like a rubik's cube if you only turn one wouldnt it?

[alisaele1]

so awesome

[georgetroulis]

Do you mean that if you solve the one cube, the other isn't solved?

[mobradovic00]

Oskar,No offence but why do most of your puzzles turn kind of hard?

[JakkSpeedCuber]

On shapeway, it says " this puzzle is not for sale"

[OskarPuzzle]

@JakkSpeedCuber Now it is.

[bobomajojo2]

one word awesomeness



[jlga100]

Is possible to turn sides in the other cube? In the video you just turn in one cube

[OskarPuzzle]

@jlga100 Yes, it works in both directions equally well.

[iCellrocker]

Oscar, with your genius and puzzle building abilities, how is it possible for you to have your own following of haters and trolls?

[OskarPuzzle]

@iCellrocker Thank you for the big compliment. As for your question, it seems that I have reached a threshold level of fame of some kind. Fortunately, I do not have any stalkers. But no groupies either :-)

[rubiksboi]

You couldn't solve one cube and the otherone be solved too because if you look at both cubes, there color scheme is different.

[angryflan]

I Really want to try some algorythms on that

[25800nel]

if they both turn the same wouldnt you only have to solve 1 and the other 1 would follow and be solved

[OskarPuzzle]

@25800nel No, see other comments suggesting the same.

[Skitzo520]

so i can solve, and get my strong on at the same time?

[hazzahazzam]

so 18 490 000 000 000 000 000 000 000 000 000 000 000 possibilites

[rockplay100]

What would happen if you would turn two layers of one cube at the same time ?

[OskarPuzzle]

@rockplay100 The same what happens if you try to move two adjactent Rubik's Cube faces at the same time: jamming.

[JaredAredRed]

@OskarPuzzle I. think he ment what if you turned the center; 2 parallel sides.

[OskarPuzzle]

@JaredAredRed If one tries to turn a center (2 parallel sides) of one cube, then it will cause jamming at the other cube, as no set of parallel sides of one correspond with parallel sides of the other cube

[JaredAredRed]

@OskarPuzzle So it is two Rubik's Cubes with internet gears moving sides different from each other with a limited amount of moves? If so this would be a VERY complicated puzzle. Great for people up to a summer challenge ;)

[Smartboy7]

LOL, I can hear your dutch accent.

[RJA10001]

but couldnt you solve it the same way? just use one cube to mix it up and then use the same cube to solve it. wouldnt that work?

[OskarPuzzle]

@RJA10001 I do not think so.

[Robolawrence23]

is it as easy to solve as a rubik's cube?

[OskarPuzzle]

@Robolawrence23 Is as easy to solve as a Rubik's Cube squared, divided by two. You can find a Twisty Puzzles Forum post on this puzzle, and its complexity.

[yvosaurus]

Can he say his name even faster please!?!?!?!?

[The88Mason]

squared?!ioa;shdfnsakmcnbauwid­if9wohejkasuidbfiaubweiufbsoiu­dvboaunrogfinaonfdc;vlajbeurfb­oajsdnbfjncaunbweubfub aubeucbuabjsdcna

sorry, was spazzing whilst getting my asthma pump

[MrVietNinja1000]

but can it bend

[supergsx]

Can you turn both whole cubes individually?

[OskarPuzzle]

@supergsx For every turn of a face of one cube, the coupled face at the other cube follows.

[MaestroAlvis]

Great, now make them gear cubes

[guitarmasterjar1]

@MaestroAlvis lol

[hazzahazzam]

so 18 490 000 000 000 000 000 000 000 000 000 000 000 possibilites

[mitchblahman13]

intellectual weight lifters, I love that oskar

again good job man you're awesome!

[101csc101]

if I become a millionaire, I buy all your puzzle, and i start you a company with all what you need to build your puzzle haha!!!!

[7pulford]

I think that Oskar should create a new youtube channel: OskarAssemby (or something) in which he uploads videos of him receivng the shapeways parcel, dying the parts, and putting them together. I would LOVE to see that process for some of his more complicated designs (like this one)

[xkevxify]

you are such a genius!!!!!

[FireCuber]

omg! no such puzzle

mass produce it!

[96Towers]

How much is it oscar i want this one really bad xD

[OskarPuzzle]

@96Towers You can buy a set of parts through Shapeways or an assembled one from me directly. The original prototype is still for sale, so be quick :-) Note that the price is significantly higher than the cost of two Rubik's cubes. I hope you understand.

[videocatcher234]

Do you ever actually solve the puzzles after you make them?

[jaihindhreddy]

This will make stop motion rubik's cube easy

[Chickadonga]

Ur puzzles are always impressive

[thenewnoob123]

I'm dutch too and i'm actually laughing at your English... do you mind?

[Mindstormscreator]

So, how did you go about reducing the friction in the first prototypes like you described in a previous video, Oskar?

[OskarPuzzle]

Silicone lubrication and a lot of breaking in. 

[BeltedYapper]

why different sticker layouts?

[RCTACameron]

So is that about 180000000000000000000000000000­0000000000 combinations, or did I do my maths wrong?

[freddiejos]

How did you solve the problem of friction? I assume this is the evolved version of the barbell cube...

[EMI94100]

@freddiejos check the twistypuzzles forum

[OskarPuzzle]

Silicone lubrication and a lot of breaking in.

[CadenceCPK]

@OskarPuzzle I thought the silicone soaked in.

[OskarPuzzle]

@CadenceCPK Yes, that is a problem. And if I use too much then the stickers peel off.

[PowderedDoughnut]

In the prototype you described the situation as creating too much friction with the gears. How did you overcome the issue?

[KoalaKares]

mind = blown

[cammobox]

so altogether this amazing design would be about $500-$600? i think mefferts should definately mass produce this so that it would be about $50-$100 and do the same with your 17x17x17 to bring that down to like $200-$400

[OskarPuzzle]

@cammobox I believe that the complexity of this gearing system is beyond affordable mass production. Same for the 17x17x17. But if you can find me a producer willing to invest, then I am always interested in making a deal:-)

[Crazy56U]

This may be a stupid question. but I remember that the earlier version of this had a problem where you could only turn the side of one cube, but not the other. Is it fixed?

[TheRubixGuy]

@Crazy56U i guess so

[OskarPuzzle]

@Crazy56U The lubrication and the stronger centers help. Still, I can turn one yellow face both ways whereas I can turn the other yellow face in only one direction.I have yet to analyse this cause of the directional jamming.

[rainpaw4]

if it didn't cost so much i would be skinny after playing with this for a couple weeks lol

[Creewler]

verry great idea! 

[Manologft]

what happens if you turn an M slice??

[pirsquared99]

@Manologft I don't think it's possible to do that, since the faces are coupled in ways that make opposite faces on one cube not necessarily opposite faces on the other cube.

[stewinsalot]

I do 1000 reps with this every morning

[clearmenser]

Yay! I'm happy to see that you got the mechanism to work. Can you tell us please, what was the key to getting the mechanisms to work correctly? If I remember right, last time you had a problem with friction?

[OskarPuzzle]

@clearmenser Silicone lubrication and replacing the centers, strengthening the connection between the centers and the gears.

[youtunezzz2]

You are awesome and amazing!!! I want to buy one!!!!

[superpoop899]

HE SAID DUMBELL!

[OskarPuzzle]

@superpoop899 Yeah, my abuse of the English pronunciation is becoming sort-of iconic, I am afraid:-)

[guitarmasterjar1]

this is amazing! but why arent the colours in the same position in both sides? is that the challenge?

[OskarPuzzle]

@guitarmasterjar1 That is on purpose.If they were identical, or mirror image, then the puzzle would be as easy to solve as a single Rubik's Cube.

[ninjalamprey]

Beautiful and Amazing! Excellent work, sir!

[90rubixcube]

ok nerds lets do some weights =)

[PuppyZwolle]

As a puzzle I'm afraid it's unsolvable but as a piece of engineering I absolutely LOVE it. Now this would be one of those puzzles I would love to see in a clear, transparent version... Maybe even done in glass. I know 'far fetched' but man would it be a work of true art.

[SEBUVER]

@PuppyZwolle I wouldn't say it's unsolvable. Just basic but complex algorithms would be required in order to solve the second cube.

[PuppyZwolle]

@SEBUVER No, not unsolvable, but as solving one takes some advanced thinking (provided you don't go 'through the motions')... solving two interacting ones takes that thinking to a level you rarely see in humans. Or to put it bluntly:

You need to plan every twist until the solve before starting. You will not stumble across a solution in both cubes at the same time.
