In my quest to build the most reliable marble clock ever I went and built a rotary cam marble selector, 15 cam disks a spur gear reduction with a beveled set to change the rotation plane and lots and lots of 3D printed parts to make which I hope will be the solution to all my marble selection problems.
I went back to glass marbles and something I don't mention in the video is that I like way more the sound of the glass marbles knocking. It is a little bit like music.

Make a millisecond clock
Alright, what madman are you.....
Do NOT give this man any more ideas
Perhaps with moving mirrors to show the correct marbles.
@@JuliusHuijnkthats genius
@@JuliusHuijnk would that still count as a marble clock? :P
Casually mention you had to reprint two kilos of filament is hilarious. ;)
Hilarious? yes. Expensive? YES!!
@@joshuanafziger7612 Should be recyclable into more filament, though.
where
@@Speedgaming802 at 9:17. He doesn't say "2 kg filament", but "all the cam discs"
@@hoej thanks
This really undersells how AMAZING that cam stack is! For those who didn't catch it, the fifteen cams are all different because the shape of each number is "written" on the cam stack, which the marble selectors then "read" the same way a phonograph reads a wax cylinder. That means there are 20 positions encoded on each disc; 10 white or black positions which control what color marble that track uses for each digit, then another 10 release positions between them which allow the selected marble to drop.
Yes! The entire video I was stunned by how much work he must've put into calculating the cam profiles 😂
The amazing thing to me is how he put them all together for prototyping. I'd have just printed it all in single barrel instead of individual discs and would have had to reprint the whole thing if I messed one up. Granted he did say he had to print them all again but then after that was just some fine sanding to perfect.
I love mechanical solutions. I am a software engineer, and it's so trivial to do a lot of things. But before software, we had people doing amazing things with mechanical solutions. For example, way back in the day with clockwork automatons. Some even played musical instruments. Thanks for explaining the cams in more detail.
This is exactly what I was going to ask. I couldn't figure out how the cam stack was choosing the marbles. I thought all of the disks were the same. Now that I know the disks are all different, it makes sense! Thank you. Adelante Ivan!!!
@@EkiToji you are not alone in that approach, I have lost count of the number of engineering interns all the way up through senior engineers who would design large prototype parts like this as a single piece with zero adjustability or opportunity to replace sections when an issue is discovered.
After several such issues with my own designs I have changed my process to, "design as though something is wrong with your design but you don't know what it is yet."
It takes longer initially, and sometimes is "wasted" effort, but it usually winds up saving a lot of time and headaches when troubleshooting a new design...
Once the prototype is working well, THEN you go in and combine pieces together to simplify future versions.
These videos are not long enough, or frequent enough, but I'm simultaneously amazing at how much has been achieved!
Yes you are amazing brother
Yeah, I feel like he doesn’t think we are interested in how much work he puts into these videos. I can tell he went through a lot of work to be able to present this to us, I’d just love if he would share it with us. (Maybe second channel if not main 😉)
*amazed
Have you guys ever considered that he is already putting in a tremendous amount of work into these videos and is producing as fast as he can while hopefully still having a life?
When you look at engineering time, the sheer number of things he has to 3DPrint, and the time it take to print all of that, then troubleshoot, make alterations, rinse recycle, repeat, and then film, edit, and finally upload… his timeline starts to make sense.
Glass is definitely a good move, was really struggling to see the display last video
I wonder if it would be possible to make one color glass and the other color steel, which would make separating them from each other a cinch. (Magnets!)
Then again, at least for the one second update display, I'm not sure the black marbles really need to be there at all. Just send the white ones. For the next digit over that only changes once every ten seconds, sure, use two colors as usual. But on the high frequency display, only using white marbles means it can send them back to itself without sorting. The sorter is probably fast enough to keep up with one change every 10 seconds. I'm not sure it's fast enough to keep up with a change every second.
He could use a back-light and some clear marbles.
@@RingingResonance That's just cheating
@@RingingResonance so basically a 7 segment display that shows the numbers, and clear marbles in front that do nothing? then there would be no reason to swap marbles at all which defeats the purpose, unless im misunderstanding
@@Scotty-vs4lf no, replace the white marbles with clear or translucent marbles and use a steady back-light.
I think this is my favorite video in the series. The use of cams is a rather ingenious solution to the problem.
The use of cams reminded me of the flip displays shown by LOOK MUM NO COMPUTER. The main difference is that this clock's cam can be run in either direction, but the flip display is only built to count up.
It took me until he put it into the stack to figure out how he's going to get the selector to go the right direction with just a motor. Very ingenious.
@@darrennew8211
I still have not seen it. I'll go back to the "put it into the stack" part again.....
Oh, I'm an idiot. I was trying to figure out how it can select each marble as needed to make the number. But it's counting seconds, and they come sequentially. I had seen that he had the cams staggered and that he had to number them 1-15. It took me a second....
@@TomwithaDream Yep. It was like figuring out the puzzle in an adventure game. I love it. :-)
It's so cool. It's like the electromechanical machines of old!
When you said you wanted to do it all with one motor I thought damn no way but then you proved it in an elegant design I love it !
I still don't understand how it will work with ball selection...
@@ajbp95 lol truth it seems not possible but I would’ve said the same about the number selector so maybe he’ll prove us wrong
@@ajbp95 It took me a minute to figure it out. Remember that it's the same sequence of colors for each position, because it's the same sequence of numbers. The middle ball will be black for 0, black for 1, white for 2, white for 3, etc, up to white for 9. So the cam going once will select 10 different colors in each one rotation. I didn't figure it out until he showed the whole cam stack and I realized the non-smoothness is part of the design.
@@darrennew8211That doesn't answer the question raised by @ajpb95
Your answer is how the part shown in this video works. The question they asked is how the marbles will be sorted in the first place.
For the mechanism shown in this video to work the white and black marbles have to be separated beforehand.
And @ajpb95 and I have no idea how to do separate the white and black marbles with one single motor driving the whole mechanism.
@@Jehty_ I misunderstood. I assume he'd use the other marble sorter he already showed, but you're right that requires solenoids.
When this clock is finally finished, and put on display as a monument to creative engineering, everyone will stop here every time they watch this series, to just absolutely marvel at using 15 cams to solve this problem.
Theres something awe inspiring about seeing massive 3d printed gears.
I love that made them so aesthetically pleasing too.
I love how what is seemingly an over-complicated contraption is actually the most efficient way to achieve your goals: that's engineering, baby! Would it be worth building a device that sorts marbles by dimension so that you don't have to go in with calipers and do it yourself? Chicken eggs are sized by machines that have rails with different gaps between them so the right sizes go in the right bins- perhaps 3D printing a jig that you can dump marbles into like a coin sorter would make it more viable to get the huge number of marbles you need to fill and maintain this machine. Amazing work!
Great idea can u make sandwich
The answer to "would it be worth" is in comparing the time it takes to sort by hand to the time it takes to create sorter. Also, creating sorter would mean a new video, so more content, which is a plus. On the other hand, you need to sort millions of eggs every day, so engineering an egg sorter will increase your "time profit" with time, while here he will sort a limited number of marbles, so "time profit" is limited.
If I was in his place, I would do it for the sake of content itself, but it is his channel and his time is spent on it, so he is the one to make the decision what is worth to him and what he wants to do.
I don't get why he decided to sort by hand.
Just drill (or print) a hole the right size and check which marble fits. (Might have to check each marble multiple times to make sure that all orientations will fit)
@@martinmarc715you just need to suspend two rails next to each other, it's very easy to make this kind of sorter.
This is how Tower clocks in the medieval times were made. I mean the materials and tools are different, but Ivan's thought process and approach to solving the mechanical issues in front of him while building a clock must be very similar to the ones, that the ancient clock builders of the medieval employed to solve the issue they faced. Love this series.
glass is good. The steel marbles are hard to see.
This is sooo much work. I can't state how i'm instantly clicking on your vids to watch it.
Yes, expired cakes sound like a reasonable alternative to marbles 👍
What about marble cake?
Don't be ridiculous, that would never work!
@@yvan2563 Hmm, you might be right. You would only get half of your daily recommended amount of cake otherwise.
I do love a marbled cheesecake...
Expired marbled cheesecake balls
this is incredible. if this isn't at OpenSauce next year it would be a travesty!
Do you even need 2 colors of marbles? In the previous clock black marbles were acting as spacers. In this design I think you can just route white in the shape of numbers without any spacers.
It would totally works and lower the complexity by a lot more than 50%, but would it still count?
I mean, he could also simply put fixed marbles in wheels for each row and rotate the correct combination as needed for each number.
I think he should do this for the once-a-second digit, so that it won't run out of sorted marbles (it would just have its own collection tray and feed back into itself). The sorter can probably keep up with the other five digits. The nice part is that he doesn't have to redesign anything, just don't load any black marbles. It will still go through the motions of trying to send a black marble, but that's harmless.
Little late now XD
@@chkn_boy Not too late for my suggestion (don't put any black marbles in the fastest digit). No alteration to the hardware is required, just don't give it any black marbles.
It would work for the seconds because of the way they stack, but wouldn't work the same as the rest and would look odd compared to the others. Maybe keep this as a last resort if he can't figure out how to get the current planned way to work. I have faith he'll figure it out though, he's already figured out solutions to several silly tier difficulty things.
I love how he says "I even had to reprint all the cam discs", like it was just nothing. The amount of time and money spent to make this for us, AMAZING!!!
It took me a few minutes to understand what was going on with that stack of cam disks but when I realized I was blown away. It’s so simple and clever
I think many people would love to see a second channel of yours with more frequent but not so finished videos just to see how things are going.
Like the problem solving and other issues you run into
i have watched every part so far
You are a CAD CHAD my man. That assembly/ prototyping would have taken me a lot longer than the time you had since your last video. Hats off to you sir.
With all that knowledge with timing those steel marbles and solenoids, you basically have all the knowledge to build an extremely over engineered pinball machine.... That is something I would love to watch!
another amazing video! as a student engineer, I appreciate the complexity of this, would love to see a more in depth video on the designing process
Kudos on the cams - You can do so much with cams, the old automata used them extensively, even old gambling machines used them to provide "random" outputs!
These videos don’t do justice to how good of an engineer you are. Incredible work and brilliant solutions (and execution)!
gosh i LOVE the analog coding of the ten selection positions per channel. that RULES.
I'm getting deja vu!
Me too!
The 80's action montage music was also fun. The machine though is so impressive. It actually works!
What an absolute madman!
Single handedly keeping the PLA industry alive!
Jokes aside, what amazing work. The cam stack with the spacers was super cool. Can't wait to see everything put together.
Having the videos longer where you explain the process of designing the 3D printed parts and the reason behind them instead of them just being done and working perfectly would be great.
Cams are a genius solution for this. It's like programming the system. Hard-coded if you will. Thanks for sharing!
Great progress! Very excited to see the seconds clock fully functional and working next to the hour and minute clock
After the clock is finished I'll probably go back and binge watch the whole series of videos. So much fun listening to Ivan explain it all.
Love seeing the embrace of cams! Definitely the way to go when the pattern and how it changes over time is known in advance!
This video series, I kinda forget about, but look very much forward too watching every time a new video comes out. Mainly just for the shear amount of troubleshooting that is needed to get this project up and running.
A MUCH more elgant solution! You've discovered (or rather, introduced to the audience) mechanical programming!
So happy you're using glass marbles! I hated seeing you struggle with the steel ones and I think this looks way nicer!
I'm convinced there's a much simpler way to build a marble clock. That being said, this is really cool!
Je m'attendais pas à ce que les nombres soient codés dans les cames ! Impressionnant !
Vous êtes quelqu'un de très inspirant, le type de savant fou qui me donnait envie se créer ce genre de machine quand j'étais enfant.
I’ve been watch this journey for months and I still get impressed with the things this guy cooks up
This is just bananas. Love this series.
I like your elegant solutions to problems, especially the ones that require incredible forsight and prediction, such as how to join the sorter, display, and feeder pieces together. This takes alot more time and effort than you portray in the videos. The art of good design is to make it seem effortless. Well done so far! Looking forward to see it all come together 😊
Your ingenuity and perseverance is truly inspiring.
I like the stack of discs that has the digits preprogrammed, very clever!
This is fast becoming one of my favourite channels on TH-cam. Your problem solving persistence must be commended.
the amount of thought and physical effort you put in is amazing. Really a joy of a series
I love your over-complicated clock. Keep working. you´ll get your clock working.
If consistency and engineering had a face, it is this guy. I love him❤
I'm so glad I stumbled onto your very first marble clock video; I want to see it through to the end, no matter how long it takes.
It's so weird to think that the first video was 3/4 of a year ago now... Turns out time flies when you are waiting for the next part lol
All I hear is we need a marble calendar.
we're only waiting for a second, really.
@@kepstin took a minute to understand but I think I got it now lol
But at least there's hours of content on the topic now.
At first, hearing you say you wanted to do everything mechanically with one motor had me reeling in horror at how complicated that was going to be, but after seeing that cam stack... omg I think that might be waaaay more elegant and simple than all the other alternatives. (not to mention... a hell of a lot cooler too)
Ivan.. you’re incredible man. I just smile in excitement watching your videos. I love your transparency and that you help educate while you’re making content. Keep up the great work!
Thank you for your hard work and dedicated time for this project; please be well😊
You are so full of joy and excitement in your videos. They always make me feel better😊 Thanks man.
We all have talents in different areas. I am so thankful for the inspiration that comes in software engineering for me. I am amazed nonetheless by the inspiration or design that comes to you in mechanical engineering. Maybe that comes a little by experience too, just doing the stuff we do until it becomes something we can create with plus the University degree. Anyways, if I get a chance it would be fun to design more in Industrial Design which I think you do some as well since it isn't just parts and unsightly prints of default mechanisms. In all, I think I'm just talking about something I heard of as design thinking.
I love the decision to go with a single motor, it's much more "clockworky" this way. Also, cam wheels are awesome!
You are crazy! Its so satisfing to see you explain your subassembly at the same time the work you put into the design just 🤯
I love this project! Been watching it for a while, and every video I end up wanting to make a clock of my own. Thank you, Ivan!
Things normally spiral out of control, somehow you're spiralling this project into control 😅 I love every second of it!
Ok, you are a man of sheer unyielding will.
Glass was a good move 100% I am constantly amazed by the amount of effort this guy puts into every video.
When this is all done, I hope this whole design gets put into a museum somewhere with the right resources to keep it running. It needs to be on display somewhere for sure.
Loving it! I'm imagining how this machine will look with 6 digits! Mega-nificent!
I admire your Persistence Ivan!
Man you are working on solving the most ridiculous and unnecessary problem... and I'll watch every step of the way!
This just keeps getting crazier
The mechanism is mesmerizing.
You should rebuild the entire clock with it, it would be huge and works really well with the all mechanical aspect of the thing.
That's just brilliant, Ivan! 😃
Looking forward to the next steps!
Stay safe there with your family! 🖖😊
That cam stack is glorious, can't wait to see it in action!
This one-motor design is so cooler than the other one, I mean this is basically pure watchmaking
That cam disk stack looks amazing! Great work on the design!
this thing looks absolutely sick my guy. 12/10, please do continue.
That stack of cam discs is insane and quite an engineering feat.. Awesome job :D
You, sir, are a marvel of joyful indomitability and ingenuity!
I love your problem solving abilities and your sheer genius.
This is my favourite project on TH-cam
This machine is absolutely beautiful!
You are DEDICATED!! Total engineer mentality, love it. You deserve a million views. I always found cams fascinating, so it's cool to see your cam idea.
I do love his drive to make this work
I really enjoy your video serie about the marble clock. I like your process of thinking, as an engineer and maker myself (anecdotally in the watch making industry) I can see all the efforts you’re putting on the design and the making of this beauty. Cannot wait to see the final clock.
SO COOL. Id love more of a breakdown on the creation of the cam profiles
This video series is awesome. You must really love this stuff, cause all the calculations and engineering makes me dizzy just thinking about it.
loving the new design
I don't know why, but I am 100% invested in your marble clock
I love your dedication on perfecting this one, but it will be nice to see a new project... Hope you finish this one soon. 🙂
lol the new wintergatan channel! Just digging deeper and deeper into marble madness! Love it!
Joke aside, I really like your problem-solving skills and your way of thinking.
I love that we live in a society that can turn ones obession into a marvelous lifestyle.
This series is just getting better and better with each post!!
I can't wait to see what you share next!
When you showed the cam stack I got so hyped I audibly gasped!!!
I feel like you don't actually need black marbles if you're feeding the display from the rear. You needed black marbles on the minutes clock to act as spacers because the rows are fed from the side, but here you're feeding from the rear. Eliminating the need to sort white from black, and make channels that can select which color to feed, should make it a lot simpler.
Probably.... But it keeps it consistent in the noises it makes, which for a huge display clock like this is part of the point of it.
Insane. The work involved, problem solving and above all.. persistence!
Marble machine has been outclassed, this is fantastic
I love what you’re doing 😊, now with glass marbles (and if one of the colors with similar friction is metallic) a separator is possible to be able to feed the marbles back into the system 😊😊😊😊 … eventually
but I'm simultaneously amazing at how much has been achieved!
I absolutely love how complicated the seconds clock is compared to the minutes and hours only one
I'm so much looking forward to the next iteration.
This is stunning! Such a work of art already!
This channel is the best mix of Wintergarten meets James Bruton
Here he goes! Inspirational attitude. Go get it man!
This is such a great project.
Not only is the result super cool the process is illuminating and interesting.
that's pretty cool. looks like a ton of work off the screen. I applauded you in that. thanks for the video
