Quadrapult

[H4L0GaNGT4R]

You know, one might jump to the conclusion that this guy is a total loser, but you know what? He's doing what he loves, and judging by the video, he has the finnance and know-how to live out his dreams. He's got his shit together, do you?

[qbacody]

fajne

[quatfro]

Never has so much time been wasted to achieve so little!!

[andthemouse]

Now make an Octapult!!!

[BLitwin]

I DID make an Octapult. Go back to my channel page to see it. : )

[Bilb1115]

....this is almost erotic

[3rdEnemy]

Wow art that is actually awesome, unbelievable!!!

[G4mmaman]

Absolutely amazing. (But what is the point?)

[Previlant]

Someone has way too much time

[BLitwin]

Too much for what?

[wellersl]

@BLitwin PERFECT answer! LOL!!!

[HeadShot360IN]

@Previlant wow, you watch youtube? someone has too much free time

[presbarkeep]

Where can I buy one? Right now. 

[perazaroberto2]

good

[inr21sevier]

will then there u ya go have fun with it. @BLitwin

[BLitwin]

Many other fish to fry, my friend. Check out bradlitwin-dot-com :)

[inr21sevier]

ahha hmmm try gravity propelled wit waits instead of plastic balls to kinda move a probably different spiny disc design. nice thoe i would but no crafting tools here :( thanks @BLitwin

[BLitwin]

That's a nice idea. It certainly would be less noisy. -B

[inr21sevier]

so is it gravity powered or spring loaded or neither any help? @BLtwin

[BLitwin]

The rotating ramp cam, which controls everything else, is driven by electric motor.

[markmarkmarkmerman]

This is so cool I want to make one asap!

[pupustinki]

COOOOOOOOOOOOOOOOOOOOOOOOOOOOO­OOOOOOOOOOOOOOOOOOOOOOOOOOOOOO­OOOOOOOOOOOOOOOOOOOOOOOOOOOOOO­OOOOOOOOOOOOOOOOOOOOOOOOOOOOOO­OOOOOOOOOOOOOOOOOOOOOOOOOOOOOO­OOOOOOOOOOOOOOOOOOOOOOOOOOOOOO­OOOOOOOOOOOOOOOOOOOOOOOOOOOOOO­OOOOOOOOOOOOOOOOOOOOOOOOOOOOOO­OOOOOOOOOOOOOOOOOOOOOOOOOOOOOO­OOOOOOOOOOOOOOOOOOOOOOOOOOOOOO­OOOOOOOOOOOOOOOOOOOOOOOOOOOOOO­OOOOOOOOOOOOOOOOOOOOOOOOOOOOOO­OOOOOOOOOOOOOOOOOOOOOOOOOOOOOO­OOOOOOOOOOOOOOOOOOOOOOOOOOOOOO­OOOOOOOOOOOOOOOOOOOOOOOOOOOOOO­OOOOOOOOOOOOOOOOOOOOOOOOOOOOOO­OOOOOOOOOOOOOOOOOOOL

[i3ds]

That is really amazing... I like how well synchronized you got it working. Amazing craftmanship!

[magnadox]

dude this is beast, should be in a museum

[masterj9000]

hungry hungry hippo-automatta!!!

[DELTA1DSV]

excellent, a true work of art,

more vids plase,!!! 5 stars

[QcLoneWolf]

CLEAVER WORK!!!

Really nice pretty simple and accurate

how much time u spent to build that Kinetic sculpture?

and just for my curiosity how much u ask for that beautiful peice art?

[richhobo64]

wait, are you telling me that it is possible to make a REAL LIFE replica of animusic stuff? somebody should start working on that.

[BLitwin]

Please! This is not a replica of anything. It is my original artwork. But, the maddening thing is all the email I get about "Animusic"; the John Deere tractor parts, chain spam, etc. You'd be amazed how many folks thing that's for real. I can only hope that those fellows have gained something worthwhile, for their endeavors. I actually tried to communicate with them, years ago. They wouldn't talk to me. Feh!

[richhobo64]

I didn't say that THIS was a replica, just that it could be possible to make a replica. and they probably didn't talk to you because they worked themselves into a coma trying to figure out how those animusic sets are supposed to work. XD

[BLitwin]

I figured that's what you meant, thanks. I'll will say, if you don't want to drive yourself into a coma, try for something that doesn't eschew the real-life, statistical nuance, as postulated by Murphy's Law; much less, cheat the well-understood behaviors of Newtonian mechanics. 8^ )

[cordellrich]

Coolest thing Ive ever seen in my life.

[welstijlfilms]

I published this video on the Dutch website WELSTIJL (8 january)

Kind regards Sem Mallée

[1001lool]

reminds me of animusic pipe dreams 8D

[Zetune79]

Wow... the balls never collide. It would be cool if they did collide each time and then turn 90 degrees to land in the adjacent cup rather than opposite. But I dont see that happening without a vacuum and a nasa budget ha ha.... another awesome machine !

[YEB100]

oye felicidades esta exelente esto es creatividad pura.

[billysgeo]

UNBELIVABLE CRAFTMENTSHIP.

Was it made by hand, CNC machine or both?

[BLitwin]

Thanks Billy. I have traditional woodworking and metalworking machinery, but nothing computer controlled. -B

[billysgeo]

Even more "respects" to you then...

One more: Is the motor underneath an AC or DC model? How do you regulate the speed? Are gears involved? Can you post a video with the "innards" spinning?

Thanks again...

[BLitwin]

It's a shaded pole, AC gear-motor, off the shelf from McMaster-Carr for about 50 bucks. There are no "innards" to speak of, really; just the motor, a shaft, and a cam/microswitch for automatically stopping it at the right spot. -B

[upgrayedd101]

thats friggin sweat

[ummmkewler]

you say in your description work for sale how much for this

[woopertdebear]

Fabulous!

[LoserBot]

I read that you use a spring to create the force behind the catapults, is that correct? I didn't notice it in the video but am intrigued by the precision of these catapults. How did you calibrate the springs, and do they weaken over time?

[BLitwin]

Yes, the catapults are powered by extension springs. They are "calibrated" by the empirical method. That is, when the ball goes in, the adjustment is set. Since the amount they are extended doesn't come close to the limit of elastic modulus of the spring material, they won't wear out for many years. -B

[jookbox101]

genius brilliant

[Legified]

GREAT JOB. im impressed on how your able to build something that is able to shoot balls into those cones and not have them miss. btw, is this powered by electricity or batteries? :p

[BLitwin]

It's powered by a 110V AC gearmotor, underneath.  A battery-powered version is entirely possible, however.

[Legified]

ahh i see. still its really nice.

[GSADV12]

Goood job!!!!

[20RoyalSuperKing]

Do you ever display these? I love enginering and art put together.

[BLitwin]

Yep. I do shows with some frequency. If you'd like to join my mailing list, send me a private message. -Brad

[puliukko13]

Is this idea yours? It's genius! Maybe useless, but cool!

[BLitwin]

In as much as any idea can be the sole province of an individual, yes, I suppose it is possible.  But, the embodiment of the idea, in as far as I can determine, is most certainly, and entirely my own property.

[joh04667]

damn good answer sir haha

[robotgrass]

a joy to watch-well done

[peabnuts123]

Very clever =)

Well engineered this is.

[AntiChristxD]

wie geil :D

[bonski2008]

how is it powered? winding a spring?

[BLitwin]

AC Gearmotor -BL

[GavinS1965]

Beauty!

[motorbreath302]

That's awesome, great piece of work there. Amazing.

[tryally]

Very interesting!!

[zskar]

do you know what wouldve made this 5times awesomer? makin the catapults spin around the wheel instead

[Hyuga777]

Do you realize how insanely stupid you sound? that's what the 'audio preview' button is for.

A) how would the catapults receive balls?

B) it would probably be hard to calculate all the possible catapult - tube things, unless they were done 1 specific catapult to tube thingy, which would go against what you suggested right?

[zskar]

whatever smartass

[sethjees]

I know what would have made this 5times more awesome. Smashing it to pieces with a hammer and putting it in the f***ing bin. What a load of cock. The fella that made this needs to go out more and possibly get laid.

[zskar]

true that, so do you

[BLitwin]

My my. Such comments. In fact, I have built a spinning Quadrotapult. Look for the video in less than a month. I promise, your jaw drops. -B

[m0eme]

Hypnotic

[knexman25]

Its so amazing yet irratating that i didnt think of it

it ROCKS

[1cemage]

wow.... i could play with one of those for hour. very well made. the craftsmanship is exceptional

[CaptainPoochie]

Thats amazing

[Animesenhista]

Very cool!!!!1

[Gojuryu00]

what's making the central wheel spin, It didn't show it being driven by kinetic forces.

[54spiritedwill54]

omg you are great dude!

[freethinker1969]

My last comment was in response to LACR0SS3F0RLIF3 - I loved this video and sculpture.

[bangalaheng]

hey buddy...do you have any idea on how to make one? which only consist of one catapult which would not be too complicated? cause i am researching on a project and would need to do one after that ^.^

[Hyuga777]

Well if you're researching it you don't need hints?!

[latheworks]

It's good to see this contraption from dif angles. If you look carefully, you just might come to learn something. I liked it, not that I intend to built one as I'm tied up in a 1000 projects but it sure must have taken a lot of time to build and adjust!

Thanks for uploading this!

[LACR0SS3F0RLIF3]

this is very coolio but it is to long of a vid for one thing

[BLitwin]

Who made you watch the whole video?

[LACR0SS3F0RLIF3]

well who wants to watch a 2:16 video of just one thing? it was cool but just to long...

[BLitwin]

Evidently, around 37,000+ viewers would disagree with you, so far.

[NinoScript]

i watched it twice

[freethinker1969]

What a weird thing to complain about! Go find something else to do!

[LACR0SS3F0RLIF3]

ok can we just stop talking about this!...holy fuck! it was a cool thing...just shut the hell up!

[Shannariano]

this IS art

[jrompe]

NICE BALLS! XD

[NinoScript]

lol! xD

[AlexLPD]

nice work, am impresed bye the quality of the manufacture, When i grew up i like to be like u and build amazing stuff like that

[littleseanx]

cool little beat isnt it?

[kbthfrtedserg]

Hello,

it´s possible to calibrate the pult? How did you confirm, that the ball meet the bowl?

I build a marble machine and your machine is a nice inspiration for me.

[BLitwin]

Thanks Michi. I looked at your marble machine, which is a lot of fun, with a unique aesthetic. So, catapults are calibrated in two ways. First, the release angle has to be determined for desired trajectory height vs. downrange distance. Consult your high school physics text for theoretical calculations. Assuming your design has no inherent flaws that impart unwanted behaviors, final calibration is made by adjusting the spring tension.

[rubycubies]

thats so cool

[darkito81]

Great, Wonderful and beauty of moves.

[axelgrease]

Thanks. You are truly great. I am an artist as well.

[xmxmal]

....this would take a lot of technical skill to make!

[vsimoul]

very artistic!

do the balls ever collide in the air?

[BLitwin]

Thanks for your comments, vsimoul. Actually, the balls never come any closer to one and other than about 3 inches. -Brad

[slikind]

pretty nifty

[skeype]

WOW thats neat!

[johnnyFFM]

omg you are fuckin great dude! how many hours did you invest??

[BLitwin]

This one took about 2 weeks to make.

[johnnyFFM]

wow not bad.. is this your profession or a kind of hobby?

[BLitwin]

Yes, I'm a professional artist, though I make my living as a musician, primarily. I'm hoping to turn it the other way around, someday.

[johnnyFFM]

ok so good luck mate! hope you'll do fine

[knexgun]

this is fore sale, plus other works?!! where can i find them? how much do they cost?

[NSResponder]

Yeah, saw the rotapult. Just how ambitious do you think you can get with this? Maybe two concentric rings of counter-rotating launchers with balls being passed from the inner to the outer ring?

-jcr

[BLitwin]

Sounds like a project for you!

I do work on commission, by the way.

-B

[NSResponder]

How long did it take to fine-tune the launches to hit the cones?

-jcr

[BLitwin]

Really, just a few minutes. The bigger challenge is calculation and design for force, launch angle, and in some cases, transit time. (See the Rotapult (YouTube...) /watch?v=dauoL7U7zEU

[dtc2002]

OMFG THAT IS NEAT

[271828183141592654]

Great.

Simplicity and beauty combined.

Art thru mechanisms.

[tomsindahouse]

WOWZA!

[changcat]

I've been making Automata on and off for years (not very well I might add) but this must be one of the most amusing I have ever seen. If you have a set of plans for sale, I would be very interested. Des

[umarinam]

great
