Catapult marble machine

[thatrandomkid10]

you my friend are a genius

[dodoplate1]

this took 50 years to get it just right

[squarewave2]

Thank you!

Can you tell me how you solder, braze or weld the wore together??

JM

[squarewave2]

Can you please tell me what is the wire material you use to make the tracks??

Thank You,

John

[denha]

@squarewave2 1.0mm brass wire.

[notexactlyIO]

Awesome! That's a very ingenious mechanism that only lets the catapult get one ball at a time, but doesn't change the way it throws.

[warossmann]

Absolutely Perfect, because a lot of attention to detail.

This works better than my PC hihihi.

[jntire1]

Hi Denha, i would love to buy one of your rollers, how can i do it or find them? i have a welding and tire shop and that will be great to show on my shop here in Puerto Rico

[Revstoningpot]

interesting invetion. I must find a way to make it larger so i can hurl large boulders at my enemies

[deviousxonex]

I want to be the ball...

[CelticReject]

As the catapult ages and parts begin to wear out, would it make a difference to the trajectory of the balls? I'm guessing yes.

[denha]

@CelticReject It is not becoming a problem a little.

[44R0Ndin]

@CelticReject if it does, i am sure that adding a larger "catch cup" to the landing zone for the marbles would fix it easily, and allow for future trajectory changes as well

[CelticReject]

@44R0Ndin Good point.

[chevypower310]

wow u know how to buy that cool

[TheBigjonhoss]

so who has more spare time--- the guy making this or the guy watching it?

[ACDC5968]

Who ever you are you have such a talent for this. I like all of the lil' marble tracks you make but this is my favorite. Just keep doing what your doing and I like that design for the catapult.

[DrStrangelove346]

I kept saying "Kobe" right before the catapult launched. The one time I said "Lebron" the marble missed. No joke.

[Insayner]

U interested in selling some? I didnt scroll though messages to look to see if you are.  Let me know, thanks

[brantcobb]

this could make you a millionare

[Coolie747]

[TamsinRJ]

I love all your work, and this one is really fun, and very different.:D

[MyQwerty678]

Exellent work!

[mightywombat]

Always inspiring, sir!

[cheesebomber1]

[chompet123]

My life is now complete.

[MrMike2blu]

really cool

[bjhennessey]

Fantastic creativity and craftsmanship. Guys like you inspire me.

[bushstalker]

pointless.. AWSOMELY COOL!!! but pointless... So umm were can i get one?

[joe47771]

i love the fast spin at the end!

[joe47771]

i cant believe the accuracy of that vault. beautiful

[HeadmasterFox]

wow, the time and effort put into it to make it that precise, amazing.

[xlitlledudex]

Pause at 2:51

[MyWILLIAMS007]

HOW DID YOU GET SUCH AN ACCURATE THROW

[MrFawadbutt]

very nice,,,and wonderful work...

how to set the angle.

[modaristis]

the balls are magnetic or do they have to be magnetic?

[seelder]

thumbs up if you were like what the hell when you saw his thumb at 1:06 its so small!

[Donswoodshop]

denha, how many teeth on pinion and spur gear? What is speed of cam?

[denha]

@Donswoodshop pinion gear:16T spur gear:60T cam speed:44rpm

[Donswoodshop]

@denha thank you denha. The sparkfun 30:1 gearmotor has 4oz-in (288g-cm) torque at 6V. The Gizmozone GH810136V3 has 250 g-cm at 3V. Why choose sparkfun?

[brokenl0ve1]

its hittin the top off of sumthin i know it is

[suragandalf]

tutorial pleasee!!!!!!!!!!!!!!!!1

[kungopus]

[jrdg77]

thumbs up if you look like (O.O) when you see this

[rotom15228]

has a nice beat to it... Anyway, I think that everyone, and I mean EVERYONE, would leap for joy if you put up tutorials on these. Thumbs up if you agree!

[haikaelong]

that spring scares me....

[CODboy10]

u should make some stuff on tips 4 marble machines

[liquidpaper128]

When will you make a MIRV marble machine?

[haikaelong]

Thats a scary spring xD

[firecracker999999]

Can I purchase this, it so much cooler than the crappy American marble machines

[yeffrey1]

What kind of woodworking equipment do you use? Do you have a router? Drill press? What should a beginning builder buy first? Thanks!

[MrKaddan]

@yeffrey1 watch?v=AOgKYIpPicw

[Stijning]

O MY GOD thats freakin awesome i thougt that they would land somewere else but right inside that bucket O.O RESPECT

[fistomania]

sehr schöne arbeit... gute ideen... hat was sehr fesselndes den kugeln zuzusehen.

[yoyohoes]

WOOOW THTS SO COOL how did make the catapult?

[idezilla]

Thank You for these wonderful videos. They make me think about things to create.

[Seigo56]

Epic!!!!!!!!!

[Machi3n]

genius

[wdomino]

you know, youre the best to make these little inventions with marbles but maybe you can make 1 big one that maybe can be a world record, youre so good:)

[beingbanana]

amazing as always

[inferarkuvio]

Where can I get one? Love it!

[ThePoeticFox]

OMG, I bet it took you forever to get the catapult aligned with the cup and the ammount of power needed to hit it perfectly.  Kudos!!!

[haikaelong]

GOTTA LOVE DENHA!!!!!!!!!!!!!!!!!!!!!

[Shypo15]

wow never thought that something like this will work ^^ AWESOME

[sumadomi]

align the axis of the cup with the direction of the parable in that point (it looks a very defined trajectory) awesome work

[overkill1994]

is it odd...or am i the only one that could fall asleep while listening to this....??!?!

[CrunchieDan]

Mesmerizing.

[MathieuVIII]

You make the best marble machine. They are gorgeous and this one is the proof of what I'm saying.

[hdhproductions7]

denha, you should somehow put all of ur awesome creations into one ongoing super creation!! thumb up if u agree!

[chiphopper]

Denha you always amaze me! Brilliant :)

[MewesK]

Awesome little machine! I like it :D

[ojom52]

Every marble machine from you is in my favorites.

[obr0]

GOOD WORK!!!

[TimGraupner]

Would it be possible to make one that's so big that every one minute exactly only one marble passes a spot? cause you could make a marble passing that spot trigger the minute hand of a clock to move. that would be frickin AWESOME

[TimGraupner]

You should combine all of your modules you've ever had, and build one giant one

[jdogface]

this is so awesome... (my greed is making me ask, when do you make the monster sized one that incorporates all of the modules?)

[a84148]

Very nice!

[SireSpamelot]

>The speed at which the ball is raised is the velocity.

what?

[Kingkong9099]

This is what i was looking for last night... GREAT JOB!

[tH0d0RHs]

this is hypnotizing!

[terransage]

Incredible!

[09fod]

that is to cool

[snowydro1]

that is so cool dude.... i wish i had a mind like yours... so cool

[gyawareturns2]

ぬおっ！　なんだこの仕掛けの凄さ（＠＠

[SAMIMYS]

بسیار عالی واقعا فوق العاده است

خیلی از کارهایت خوشم میاید

[jassuncao]

Amazing!!! Great work as always.

[ko3kenbakker]

Are you gonna attempt to fix the 1% miss?

[denha]

@ko3kenbakker I will correct the shape of the cup.

[TimGraupner]

@denha is the "divider" attached to the catapult repulsive (like magnetic). Because it kinda looks like it

[rjkhbjni]

denha What metal are you using for the tracks?

[denha]

@rjkhbjni 1.0 dia brass wire.

[FearMyMaul]

@ko3kenbakker Uhm theres always slightly veriating forces acting on the ball whilst in air the amount of friction changes the air preasure can change resulting in different amounts of air ressistances theres many vectors taken into account

[Nederdien]

@Jegowndig

China?

[Nederdien]

@Jegowndig

How do you know?

In his profile it states "Japan" ...

[jbz3]

You should incorporate a binary counter into one of those. Or better yet, make it into binary clock!

[Coolfolder]

@jbz3 great idea!

[Kayzaks]

Wow! Very Nice!

[Mugicha808]

Great work!

[mebethatthing]

super cool
