ForTheL1ght

These are super expensive btw, unfortunately :/


_N0_C0mment

There are published DIY plans, parts lists and code in electronics hobby mags you can build for a few hundred.


ForTheL1ght

Can these DIY ones do those crazy jumps from point to point though? That was a pretty big thing that the Cubeli excelled at


knullsmurfen

Teleportation chip is an extra $500.


PretendiWasADefMute

Just a few hundred?


knullsmurfen

I don't know man, I don't see myself in the market for self stabilizing cubes.


ForTheL1ght

It’s a proof of concept, so, it isn’t really about the cubes lol


knullsmurfen

If I have the proof already I don't really feel the need to buy the concept, but hey, I'm a modest guy.


Cool-Message-1005

Square..!


GeraldAlabaster

$10 for a gryroscope that comes with its own box (cube).


Beerbeisser

How? Lego mindstorms toys 15 years ago could do that already. Not like it would be difficult, and sensors and chips got cheaper with smartphones and drones. Btw, this one uses torque to provide the counter-force. Nice programming project but not *that* impressive. And the delay to reaction is a bit too high/the reaction too rough, it wobbles too much.

I think Im more impressed that thing is dead fucking silent. Im powering a stepper motor and that thing has a \*zinnnnnnnnnnnnnnnnngggggggggggggggg\* constantly


VenusSmurf

I'm glad I wasn't the only one. It feels like it should be loud.


AlabasterNutSack

This video is very helpful in authenticating this actually. It shows the cube balancing on more than just that corner. My thought watching the gif was there was a hole in the middle of the table with a rigid, but flexible, metal rod puncturing the cube and balancing it. It’s still weird that the demonstrator chose to not to bring the cube to the table and set it down at any point during the video. There doesn’t seem to be any point in the video where part of the cube is not touching the table.


[deleted]

Typically, when you’re trying to show off some real cool, genuine accomplishment, you’re not necessarily thinking of ways people will think it’s fake and implementing methods to prove otherwise. Look at the moon landing, for example.


AlabasterNutSack

That’s also because the internet is full of videos with a similar format to this trying to convince people that their great technology achievement is real. These videos are made by grifters who are usually trying to absorb crowd funding money. Like that projection watch thing. Anywho, the video linked here leaves me with an 80% notion that this is real. I’m not a special effects expert or anything though, so not sure what that’s worth. We need Captain Dissillusionment!


Jabreezy_DnD

Damn that's neat. I assume this is basically what's inside those robots that run around? Man I'm ignorant 🤣


Danabler42

Actually, no, these are often used in satellites to change attitude without using thruster fuel. They're called reaction wheels


randomcitizen42

Man, that satellite has a pretty bad attitude again today. Let's change that.


QBOOP

Attitude


relaxed_focus

Attitude: The orientation of an aircraft or spacecraft, relative to the direction of travel.


QBOOP

Indeed


MeesterCartmanez

"not with that attitude!"


Shadowleg

This type of stuff is in everything. Theres definitely ones in those robots, they’re in satellites, planes, boats, submarines. The gyroscopic effect is overpowered!


[deleted]

This is so sick I think I may go into a coma


Pebbles049

SHUT UP AND TAKE MY MONEY!


geeskeet

I mean isn’t every cube a self leveling cube


Heinous_

Everything but a perfect sphere or circle is self leveling in the presence of gravity? You got my brain gears turning.

DijajMaqliun

Haven't seen a centurion in a while....


n10w4

I'm guessing somewhere in there is a gyroscope and those things are straight sorcery.


idanthology

Motorcycles, practicality?


MeesterCartmanez

"I'm pretty sure no one wants to buy a cube shaped motorcycle" lol


Not_a_tryhard_gamer

You’d have to have comically large, massive (have a lot of mass, massive) or fast spinning ones :/


idanthology

Cool, so something like the motorcycle in Westworld is conceivable, it would need a tremendous yet compact power source, though, to maintain the spinning.


jesusismagic

Damn! That took some fine engineering skills.


Al-Ilham

So what's the prerequisite for making this? Background in mechanical engineering? Maybe a bit programming?


troyc94

Control theory and mechatronics, much programming too


Beerbeisser

Mainly programming.


Heinous_

I’m trying to build a similar thing using hard drive motors, but I have no serious engineering training. I did learn some python programming and I bought a cheap 3D printer.


Al-Ilham

About 3d printers, how much do they cost, and how legal are they? I mean I heard u can even make guns with them


Beerbeisser

No legality concerns with 3D printers, but making guns is illegal.


Al-Ilham

And I got downvoted for asking questions....


DarkArcher__

Wikipedia torque formula and some knowledge of arduinos and PIDs


Beerbeisser

Calibrating rotation/movement sensors was a bitch 15 years ago (drift of earth rotation and so on), but probably gotten better with drones and all that.


theDarkSigil

Ohhh no, I've seen The Cube. I'm not getting sucked Into fucking 4th dimensional hyperspace.

randomcitizen42

I want to have one on my office desk


SpecT22

I can balance a cube without any of that machinery. Just put it on the face


Cheese_Pancakes

Could someone ELI5? Is there a gyro or something in there that somehow controls those wheels/gears? How do the spinning wheels/gears (with ball bearings?) stabilize it so well? This is really cool, it just kind of blows my mind that it works so well.


DarkArcher__

Those wheels are called reaction wheels. When a motor spins a reaction wheel up there will be an inherent torque on the cube in the opposite direction. A simple example is a person sitting on an office chair. When they quickly twist their torso one way, the whole chair tends to spin the opposite way. There's one wheel for each axis, and they all work together using this principle to keep it balanced


Not_a_tryhard_gamer

When a wheel is spun by a motor the rest of the contraption wants to spin the opposite way with the same force. Any action requires an equal and opposite reaction


Imthatjohnnie

That cube seems to have help.


Drugrere

Well how did you expect it to work?


surrealmerican

Magic.


Vaughtzilla1981

I wouldn't say it's self balancing though. Looks like some sort of machinery inside is keeping it up


CrocodileDog

Which one would consider as part of the self.


Vaughtzilla1981

Maybe myself


jksinspades

It seems to run on some form of electricity


deviant-joy

I understood that reference!


Vaughtzilla1981

You mean to tell me that things nuclear?


Powerful_Dog_3776

Today's Stupid thought number 5:. It's good that it runs on electricity. Because if it ran on alcohol or some other combustible, it would constantly have to rebalance itself as fuel weight decreased.


Togfox

How much does electricity weigh?


altgrave

also, the alcohol would make it tipsy.


mrubuto22

So humans aren't self walking because our muscles are actually doing the walking?


Drugrere

Lol


sweetmojaveraiin

For some reason I find this /r/oddlyterrifying


LunaLapisLazuli

Got more balance than me.


BrokenSage20

That's pretty remarkable. Neat.


horonlapsi

when will it stop moving?


ResponsiblePickle284

Pretty much how we stand


knullsmurfen

What is it with the Universe and things moving?


Pristine-Motor3683

Really nice


Skulcane

Imagine a building like this. Better have your sea legs, landlubber. This contraption be MOVIN'.


DarkArcher__

Very tall buildings use a similar principle to avoid swaying during earthquakes. However instead of reaction wheels they're [tuned mass dampers](https://en.m.wikipedia.org/wiki/Tuned_mass_damper)


[deleted]

The implications of this are impossible to underestimate.


Not_a_tryhard_gamer

They’re mainly used in satellites, because it’t kind of inefficient down on earth, with drag from the air and all that. This cube, depending on the mass of those wheels would easily fall down if you put a very small weight on it. Or so I believe, fact check me if you want


Eddyibbleboi

"I can't decide whether I should tip left or right"


BluzeyBoy13

How loud is it with all those weights moving around tho


DarkArcher__

As long as the wheels are properly balanced there's no reason why it should be loud


Tarkus459

This is cool.


Kram_V

Is this the same technology used in robots?


Zalnathar

Try making a flat instead of a point.

r/blackmagicfuckery


Drugrere

How? I could definitely never program or engineer one but it seems to have a simple mechanism. You have a computer that can measure when it’s falling at any angle then that same mini computer sends metal beads to the other side of the cube to keep it up.


AquaticM00se

It’s not sending the beads to the other side, it’s a set of 3 gyroscopes keeping it up


slickyslickslick

to be more specific, the beads are just there for mass. when it detects movement on one axis of motion, it spins the wheel in the exact same direction to provide opposing force to right it. Humans do this instinctively. If you've ever kept your feet together and slowly leaned forward or backward, after reaching a tipping point, you will instinctively swing your arms in the same direction in a circle to keep yourself from falling.


DarkArcher__

The beads aren't shifting to offset the mass, they're called reaction wheels and they generate torque in the opposite direction the motor spins them in thanks to Newton's third law of motion


LaserHawk_

As mention in other previous posts about the borrow rate. That is the retail borrow rate not these inside crooks rate.
