Dear RUclips: is there any way we can nominate Denha's "Slow Motion Ball Track" video for the front page of RUclips? This artist's mechanical virtuosity needs to be displayed as an inspiration for all.
Denha, WOW just WOW! Thumbs up! I'd give you ten thumbs up if I could! Your mechanical creativity is immense! I hope you keep making and filming these awesome machines! Thanks for sharing your work!
I love these. Now if you could make one without the whirring sound of the motor, I would seriously ask you to sell me one of your lovely creatures. You might be able to utilise the clockwork mechanisms from some big bedside alarm watch. I am fine with having to wind up the thing to run.
***** Maybe personal preference. The clicking, ticking, humming of the wood and the steel is pure lovely. The continuous whirring of the motor on the other hand...
HI Denha. I love your videos of the marble/bearing coasters! you do excellent work! I'm making one myself and the motor I bought turns way too fast. Where do you get your motors from? They seem to be turning much, much, much slower than the one I bought. Also where do you get your gears from? I'm having to go to my local radio shack and hobby shop which only these fast electric motors and spur gears for r/c cars and such. I'm making what I need by rigging several things together but it looks janky. I would like mine to look a quarter as polished as yours do!
The movement in the glass is slightly random and nice too. Glass can only be so flat and the balls only so spherical. Hey denha, have you ever tried a lift using synchronized electromagnets vertically would be so silent
a disc for example with individual magnets around the perimeter. Say 10 spaced eaqually around a 150 mm disc. The magnets and spinning vertical disc are on the other side of a similar glass plate (or any other surface sufficiently thin to transfer magnetic attraction). The disc spins and grabs the balls and moves them from one station to next. I was wrong to say that balls are only so spherical before, it's safe to say they are nearly perfectly spherical.
Not clear if your disk is also spinng itself by a conventional motor. I've seen a video where a "vertical lifter wheel" has no holes, but permanent magnet hidden inside, and use them to catch balls while rotating till the top. - In general, I understand what is a linear array of electromagnets, and sure is silent, but I think cant be used to lift balls. Problem is magnetisn has a range of few mm, so you would need hundreds of them (and lots of ernergy). Tray to explain better, please.
It's been awhile since I made my first comment and now in retrospect I think I meant with a motor spinning the wheel (with magnets under glass) Just as you described seeing, which would also make noise. I do like the idea of individual electromagnets in an array. Seems doable even with simple wire wound nail ones. I certainly understand your point about the weak magnetic force, but it still seems doable. Maybe one could even take a brushless dc motor apart and flatten the circuitry behind glass. Maybe use a esc for a RC type motor with home made windings. Just throwing stuff out there of the cuff.
Thats a cool effect. I have to ask why not spend just a little bit of money and invest in a belt drive motor or even a worm gear. Both would be significantly quieter, I believe it would enhance your videos greatly.
pls.. someone tell me, what is this function?? i admit it is very cool experiment, but i am so curious, want to know, what is this thing about.. pls anyone tell me
I would like to help you. However, I am not good at English. Please prepare two rods. They are set in 10-mm distance. Furthermore, it is fixed. One side lowers. Please place marble by a higher side. It will rotate slowly and will go. Please extend the distance between them to 15 mm, and try the same experiment. It will rotate more quickly and will go more slowly. If distance is larger, it will rotate more quickly and will go more slowly. Here, it is the answer.
WHY THE HELL ARENT YOU SELL THIS??????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????? WHY!!!!!!!!!!!!

You sure have those panes of glass aligned perfectly! This was a fantastic trick of yours and it worked out great!
Favorite one so far. These lifters are awesome and the acrylic track is great to watch.
Ingenious idea! Really slow motion, but no risk of getting stuck...
I love listening to these!
this is so awesome ! I think I will dismantle my plexiglass aquarium to be able to try this !
that technic is such a great trick :D amazes me all times. Awesome as usual :D
Your work is truly next level in creativity and very inspiring! I watch this channel with a big smile!

Mark Andrews, No offense to the creator but there are marble machines that are much better than this.
Realy? Then show it to me!
Denha,

２本の丸棒をレールにしてビー玉を転がす時、間隔を広げるとビー玉の回転速度が上がり進行速度は下がることを経験として知ってはいました。それをこんな形で利用することは考えつきませんでした。脱帽です。
ありがとうございます。
これは本家ピタゴラ装置に登場していたからくりを模したものです。
精度の高いベアリングボールですから通り道が安定しています。
denha ルーターで作られたらしい丸棒をたくさん入手したのですが、このままでは真円度が低すぎて使いにくい、どうしようと悩んでいる時にこれを見ました。
サンドペーパーを張り付けた合板を二枚用意して、その間を回転させながら通すだけで、任意の丸棒が作れそうな気がします。近いうちにやってみます。
Ariake Hotakamachi それこそビー玉の製造法に似ていますね。
Lovely idea. Will it get faster as the balls wear away the plastic? It looked like a line was already being marked into the inner surface.
Fantastic ! Your brain as no limit
Very nice !
And yet another neat idea!
The lexan is a great addition!
I love these.
Now if you could make one without the whirring sound of the motor, I would seriously ask you to sell me one of your lovely creatures. You might be able to utilise the clockwork mechanisms from some big bedside alarm watch. I am fine with having to wind up the thing to run.
Why does the noise bother everyone, I'm okay with it.

Gefällt mir, wo kommen nur die Ideen her? Gibt es dazu Baupläne?
Denha, can you combine all of your lifts and tracks into one huge marble machine?
The lifting mechanism half way through is the Jahnsen linkage, right ? Awesome ideas in all those little machines!
The movement in the glass is slightly random and nice too. Glass can only be so flat and the balls only so spherical.
Hey denha, have you ever tried a lift using synchronized electromagnets vertically would be so silent
synchronized electromagnets vertically ? What do you mean?

I love the lift on this one.
+shnizalwizal which one? there are quite a few different ones shown; I quite like the big see-saw type.
Brilliant, are you selling these somewhere?
Freaking genius :)
What if you put the end of the slo-mo section into a vortex/loop/highspeed section instead of a brake? They come out of that pretty fast
ボールが2枚のアクリル板を抜けた直後の回転力を生かすことは難しいでしょうか？たとえば傾斜の緩い、短いスロープを上らせるとか(^ ^)
Hello Friend. I want to buy this machine. It is cool!
beautiful

so fuc**** awesome!
could i buy one of these?i want one so bad
Amigo, onde comprar?
magicallllllll!
complimenti.......
Awesome
amazing

grandios !!
onde tem para comprar e quanto custa
WHY THE HELL ARENT YOU SELL THIS??????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????? WHY!!!!!!!!!!!!
cool !
This would be perfect without engine noise
are these fore sale?
New Piece!!!
プラスチックのほうが綺麗で静かですね！
ガラスはやめたほうがよかった・・・
Neat

Nope

What
Fake I saw a tube in the glass
Gabe Brown are you an idiot? its just two pieces of acrylic placed next to each other in a way. it is just that simple
