In the frenetic pursuit of a working marble clock that displays seconds, in the last video I forgot to actually explain how the clock works and that was the premise for this video. Little did I know about what was going to take to do it as I was in the end going to lose this battle.
I'm already working on adding extra overkillness to it to be absolutely sure that it works and works reliably so I can already tell you to expect something absolutely bonkers for the next iteration.
As always loving to read your comments so bring'em on!!!

If there’s one thing TH-cam has taught us, it’s that you can’t just make a marble machine and expect it to work. It’s a lifetime commitment.
I'm having flashbacks.
Do anybody know how Martin is doing?
Lol I hope you like dreaming about marbles!
You know that this will make you as famous as Martin.
@@helvettefaensatan He is reassessing his life choices 😏
@@helvettefaensatanJust stuck in the ever increasing scope creep.
Wintergaten Vietnam Flashbacks Intensify
Ivan made a marble machine music maker in one episode
at least he eventually came up with a desk barrier to stop the marbles!
that was cathartic

Ah . i knew I would find some fellow Marble Fans
between this guy, and wintergarten, i've learned where the expression "losing your marbles" comes from
E
TH-cam has taught me never to build a marble machine because it will drive me completely insane. Lol.
It may or may not be possible to build a marble machine without going insane, but as soon as you try to make it more reliable, for every problem you fix you will find two more and eventually even the stuff that initially worked will break in new and interesting ways.
😂 I Wholeheartedly agree
It's fun!
As long as you are watching from a far distance someone else going bananas... 🤪
Would you say it’d make you lose your marbles?
@@AceKaci Losing your marbles is the price of entry.
Came for the marble clock, stayed for Ivan's slow descent into madness
Feel his pain 8:04
One second at a time.
So glad you found a better way to turn the balls black. That's gotta be such a relief
I was bouncing off the walls seeing a single ball being done one at a time with a propane torch. How in the heck... ?!
Protip: It attacks the stainless because stainless is primarily iron and chrome, the latter being the metal being eaten off of the marbles.
He is kicking himself in the groin that he did not figure this out earlier.
Marbles with very different surfaces. I'm waiting for the things to come... 😁
@@DrKlausTrophobieAre you thinking the color difference is causing of the giant cascade of new problems near the end? He was testing on only one color before all that.
That troubleshooting at the end really really made me feel good about the "Everything was working, now nothing is" feeling I get with most of my projects haha
E
I'm getting dangerously close to building this.
🧢
It's too late for me... I've already started 😅
I'm going to build a shed
Ivan crawled so we could walk. Also, if my wife ever leaves me I think "Babe I want to try to make this" will be high up on the list of grounds for divorce.
@@joshuavincent7884definitely a guy who doesn’t have confidence in himself 😂 If you did you would’ve logically analyzed the fact that Ivan is a person who also has the responsibility of filming this process which in turn makes the project take twice as long, and a person without that responsibility could possibly be more productive. Also, he has the advantage of seeing Ivan’s mistakes, so no, it’s not cap that he could make one. It’s just a matter of persistence.
Even an idiot can build an empire with enough persistence, never forget it.
I love that this project embodies the idea of "Make, Fail, Repeat". Love to see the rapid iterations!

So what I'm wondering... What's the difference between the diameter of the black balls and the diameter of the chrome balls, and how much rougher are they after they have been treated?
surface treatments such has used here only penetrate the first few microns of the surface (100 microns is the width of a human hair), roughness could be an issue but diameter shouldn't be at all.
I would have tested it with *all back* marbles before doing the test with mixed marbles. That would make sure that *everything* works as reliably as the silver ones and cuts out the sorting step in case it doesn't.
@@ledocteur7701Wikipedia’s page on Hair’s Breadth has a source stating that human hair ranges from 17 to 181 micron in diameter. For fine machinery, dimensional tolerances can be below 20 micron.
5 microns is the width of a human hair? Try 100 microns. You might be thinking of thou - an average hair is about 4 or 5 thousandths of an inch thick
@@PKMartin Just checked on Wikipedia, and.. well now I'm wondering where I got that 5 micron information from, cause as an industrial product designer, I was pretty dang confident about that information.
And I definitely wasn't thinking of thou, since I'm European.
I couldn’t care less about a marble-based clock. But I’m riveted to these videos because I learn so much about the challenges of design and manufacturing. I have a whole new level of appreciation for it. And the designer!
It's amazing the level of trial and error that is required to make... basically anything
As a designer I cannot express enough of how much I appreciate that leveling insight you have reached
"After uploading the last video about the marble clock that can update every second, I realized that I didn't explain how it works" * proceeds to not explain how it works * 😂🤦♂
Yes, but he now is aware he didn't... He's taking the channel in a whole new direction of not explaining things. 😂
I mean ... it doesn't work, so there's nothing to explain? ;)
@@HenryLoenwind - correct, until it works any explanation is potentially incorrect
You have an epic amount of patience for failures! The last few minutes with the updating text were hilarious omg. I would need to have a punching bag hanging nearby to take out my frustration on to work on something like this.
Yeah. I would have rage quit after jam number 3. I don't have the patience for this sort of thing.
Is it a failure if he gets a video out of it???
Perhaps you could create a ball sorter based on reflecting a light off the balls to a phototransistor. The chrome balls would reflect more light, activating the transistor. The black balls would not reflect enough light to activate the transistor. The output of the transistor could be used to activate a mechanical gate. The gate would direct the balls to one of two tracks, one for directing chrome balls, and one for directing black balls. I have seen a similar setup used to sort balls on a Lego ball machine.
That’s how the first version of the marble clock worked. He just needs to transfer that mechanism to a sorting gizmo
I have a few suggestions.
1. put a "fence" around the work table to contain the marbles, and put a little slant so they all go to one corner.
2. put a bucket there that feeds a sorting device that can divide into light and dark.
3. set to run whenever a marble is there.
That way you will always have buckets of the right marbles when you need them.
Nothing like a project to solve the problem created by working on your project. Not discrediting the idea, it's exactly what he should do, and what I'd do.
the issue is that if everything works the first time, or even the tenth time, you've probably wasted more time than you've saved - especially given this would require some kind of electronics/software
and you always want to believe it'll work before it becomes worth it to do something like that 😅 I think the rope fence is a decent compromise
@@aryst0kratI mean, he's going to have to make it eventually, he's going to have to sort those balls after they get ejected from the seconds display, so might as well do it now and incorporate it into the desk so he can be testing two functions at the same time, and saving himself a lot of time at the same time. If one or two are wrong after it's sorted 100, that's a lot of time saved
every solution introduces it's own problems............
Start a side project and build an automatic marble sorter :)
Agreed. Won't he need one anyway once this part is done?
Indeed, was about to ad a redundant comment.
Perhaps starting with a (partially) slanted table top that funnels the marbles into the sorting system?
from the fine game of pool, i learned some things about rolling ball physics and energy transfer. when a ball in a newton's cradle bumb into another, it stops. in a pool table (straight shots), it is depended of cue ball rotation. normally without any up or down spin, a slow or moderate hit speed, cue ball tends to pick up a forward rolling motion from table (instead of sliding). the target ball still bounces off with the same speed as the cue ball hits it and cue ball stops, but just for a moment, after which it picks up forward speed again from the rolling motion. in a marble track, you can add to this rotational energy for example by making the track so narrow that marble contact points are on sides near rolling axle, making it spin much faster. that spin is hard to see in a smooth ball, so maybe it could be used to make a magical ramp where balls move uphill :)
You need a magnetic floor sweeper. It's basically a magnetic bar with wheels on the ends, and a long handle in the center you can use to push it around like a broom. Your back will thank you. Though you might also need to demagnetize the marbles after picking them up.
An old CRT degaussing coil might just be appropriate for that other task.
I'm a software engineer. I can cope with the insane issues that come up sometimes while developing software. The physical world is _way_ too squidgy and imprecise and weird, and it regularly drives me crazy and defeats me. I don't know how you do it! 😻
You want/need to make a marble sorting machine also several magnets on a stick for picking them up off the floor.
Just thinking of your poor back.
Great video. Keep up the good work.
He'd want to keep magnets far away from those marbles, lest they get magnetized and stick to each other
Even Martin conceded in the end that magnets and marbles don't mix. Everyone told him from day one, but he persevered anyway...
i love how multi-material parts look, i hope this kind of printer becomes more widespread.
This all seems very unnecessary as I notice you have a watch.
But it doesn't tell marble time.
He has done the reverse of losing his marbles.
Well… you know the definition of a „Hobby“ don‘t you…?
@@SmilingDevilYou know the definition of a “joke” don’t you?

I'm starting to get some MMX vibes with this "seconds display" - it's complex, requires precise adjustment, and may never be completely reliable.
It may make sense to think about a redesign. Here's a rough description of where I would start. Consider having two marble layers at the face. The front of the display is A (current) and then B (next digit) is staged while the display is static. Until the swap, layer A is retained by a frame that positively locks it into place, and layer B is resting against layer A.
To eject layer A, an actuator would shift the frame (up/down/sideways, doesn't really matter) which would have a track shape that would forcibly eject layer A, while simultaneously shifting layer B forward partway, trapping it in place. The return stroke of the frame would then shift layer B the rest of the way in, locking it into place at the front of the frame. Effectively the mechanism would "step" the marbles forward in a controlled manner by moving part of the frame.
Depending on the angles and friction, it would also be possible to use two actuators and two frame pieces to make it more robust. I haven't quite worked out the ideal geometry for the single actuator case (it's theoretically simpler) but the geometry is also trickier.
I like this. Abandoning the ‘Newton’s Cradle’ ejection method would avoid a lot of uncertainty
A "doublebuffer" approach to rendering?
IMO It's a lot less satisfying if the marbles are pushed by an actuator at any point. Get 10 buffers and you could mount them all on a giant wheel like a flip clock. Gravity and inertia should always be the primary way that marbels move (with a lift to "recharge" them).
This is probably the best way. Kind of like the gating he already has at the top, just put another at the bottom only simpler as you describe it's just a single axis frame for all lanes. You still have the top to sort them light and dark, now you just have one at the bottom for A and B.
I’ve never commented on videos so I don’t think I successfully “@“ you in a comment I added to my recent post, but if you feel like scrolling through to find mine I feel like there might be some similarity in our thought process
You should use V-channels. The marbles will run much more reliably than on flat channels. On flat channels, the marbles tend to spin while rolling.
6:00 I don’t know why but something about that company seems so wholesome and good like if I needed a PCB prototype for some reason I would buy it from them
Sad to see another talented youtuber succumb to the curse of the marble machines.
RIP Wintergatan, and now RIP Ivan.
:)
I don't think so. Martin, bless him, was doomed from the start, but Ivan's getting there.
It seems like marble machines are really the 'final boss' of engineering lol, great video!
You can feel how close this man is to greatest and insanity at the same time. Must watch on the edge of my seat.
Glad you are always improving the loading and manufacturing processes.
I love your extremely complicated and LOUD clock! Thanks for posting these progress vids, this is a fun project to follow. You do a great job editing and presenting your progress!
So many things to love about you but the best must be
how you demonstrate the super power of PERSISTENCE!
Most outcomes are driven by skill and luck
but persistence brings ever more of both.
I'm so confused why you just don't raise the machine and have the marbles fall back into the bucket? lol
Which might have solved the rebounding double ejection problem too - they were bouncing back off balls already on the floor. Extra falling height would have solved that.
I'ts yeeears since i watch your videos, and one thing I can say is "How patient you are !!!"
Thanks for your teaching, always with the smile 😁
Ivan, I owe you a huge thanks. The orchestral song you played at the start of the video, I heard about 6 years ago. I loved it but I was never able to find it, until today. So thank you lol. Cool machine btw :D
Portrait of a man losing his marbles... but he's still brilliant enough to know where they all are at any given moment.
I'm confused why you are cycling all the marbles at the same time and not just the ones that need to change the color
*@Ivan Miranda*
8:35 The obvious solution is to print each layer above some millimeters further forward, stagger each layer.
I find it kind of hilarious how this mirrors my own way of doing things, though not on such a huge scale. For a certain game I love to play (Shadows of Brimstone; I know, to anyone who follows my comments, I NEVER SHUT UP ABOUT IT!) I've been making small quality of life improvements. Starting small with sorting trays, card trays, mostly getting rid of the original boxes to make room for more stuff. Honestly, it's become more of a lifestyle than a game. Fix one problem, six more crop up.. just.. damn.
Also, I love it: laziness is designing a new device to make a task easier. You put in work to be lazy. You.. I can't.. I can't tell if you're a mad genius or if you're fueled by the desire to be lazy while not knowing how, fully. Love your stuff, Ivan, and I especially love watching the madness that is this clock of pure evil and pain.
I'm glad I found your channel. You have this "insane engineer" vibe, like "crazy scientist" but in a fun, informative way. Love your energy !
This saga has been thoroughly enjoyable to follow. Crazy how they got stuck.. heat soak deforming the plastic?
Your videos are always the inspiration I need to keep me pushing past those issues in a design, be it hardware or code, that drive some people bonkers to the point of quitting.
Thank you for that inspiration.
I'm so glad I happened across this project. It's maddening, and when I have to make a thing at work that is a one off to fix a problem that doesn't occur in nature, I feel less alone in the land of solving an improbable puzzle.
So excited for this!!!! Can't believe I managed to catch it within the first couple hours of release! I love your videos!

Ivan: Why is no work?
The Marble Clock: I gotta poop
yesssss! part 2!!!! Love your videos!
I know, I clicked so fast 😂
Love your commitment to see it through, well done 😊

o.O
Your resilience to “failures” is inspirational. Like Edison and the lightbulb 😅. Can’t wait for next video, thank you !
The marble clock series is fascinating! Me encanta! One small suggestion to save you time... Can you invent a quick marble sorter that will read the color of a marble and dump it into a silver marble bucket or a black marble bucket? This way you can dump all the marbles into a hopper and don't have to do it manually (and it will also make a cool segment for a video!)
I cannot understand why I find this project the most interesting thing since sliced bread. I can't look away!
Truly awesome. I can just image that in the future you'll create one that works in micro gravity! Thanks for the vid.
was just thinking about your saga! Can't wait to see more!
I am always excited when I see a new chapter to the marble clock story! 😃
Your dedication to this project is wonderful
2-colored magnetic marbles. Electromagnets behind. Switch polarity, if needed, every second. No lost marbles. A marble fountain behind for assurance.
Just remember, lots of us could badly model something in fusion360. But it takes a brilliant and experienced person to even attempt such a complex project. Take as many videos as you need to make it happen, it's all part of the learning process.
This is what internate was made for.
I love you dude, your commitment to this useless thing is what made me suscribe. Especially since you show us the fails.
Most enjoyable Content on YT rn. Keep it going.
p.s. you should build an marbel sort machine
I have great respect for your patience👍👍
Absolutely incredible as always
Your patience is astounding!
Amazing content for real. Just so both technical and fun !
The amount of work you put in this project is insane, keep on !
I love this project so much.
So cool everything! Love this journey!
this feels much more like my project developments. 1 full month of non-stop work to just to end up where you started haha
you're inspiring me to show more of my failures along the way
I'm quite sure you are one of the most positively freaky guy on the world!
Your films are like hitchcock: in the beginnig there is an earthquake, and then the tension increases.
I love you and keep my fingers crossed for your marble clock! 😍😍😍
What a glutton for punishment, and always with a smile!
Good luck with revision 3!! You’re doing amazing work!
the comment on the bong killed me! i love these videos, he's one of the best on youtube!
Dude, im so glad your detumend to make this work, and I'm digging your outro!
I'm a little tiny bit concerned about what you did with the dissolved chrome, although I can't imagine that the small quantity would be much of a problem. Your adventures in clock-making are insane and I love them. I'd suggest watching Wintergatan's adventures with steel ball bearings, because I seem to recall he faced significant issues due to them gradually getting magnetized. I'd also like to amplify the comments about the balls picking up spin, leading to erratic momentum transfer.
The whole thing can possibly be a bit simplified using the fact that you Do not have to replace all marbles every second.
It is enough to replace those that need to change color. That itself will only reduce the number of marbels used.
The big advantage comes, by loading alternating marbels into the feeding channel: You no longer need two separate feeding channels (black and white) plus you also no longer need a marble selector!
That
1) saves room and material (half the feeding channels)
2) requires half the solanoids (no more marble selection, just the release)
3) uses fewer marbles (less of a mess, more time to reload)
Hope this helps!
HI! great video as always. always inspired to create new creative objects, I will take inspiration for my creations.👍
Man, i just love seeing this marble clock series! please release as soon as you can, of course i know you also are tired... (and needs to fix you back from piking marbles lol), so i hope this comes to you :D
Great engineering Ivan!
I'm not sure how I found your original video or how I got myself into another wintegarten situation, but here we are.
You're a patient guy. In my shop the whole apparat had already got many flying lessons.
I respect the will power you posess
Love your channel mate and your sense of humour 😂😂
On the earlier video, I thought "why not load the digit patterns on a constrained track?" - no sorting required. But love the overengineering of this misadventure
Greetings from San Francisco. Ivan, you are an inspiration.
I love the custom heatsinks, that being said, I'm curious if you did any extra finishing work on the contact surface like smoothing the surface or using a thermal couple like thermal paste or a thermal pad.
I love that you never give up
Thank you for these videos
Clearly pimping it out with racing stripes and proper labeling makes the whole thing at least 42% better. Well done. 👏
You are crazy 😄 Don't give up, I love your work.
If I had a 3D printer I would've joined the race!! By watching you I'm getting crazy ideas to develop this 😀
I am really enjoying the progress on this, i think a great idea would be to have a quick way to tilt your table(even just lift one end by hand) and have a collection funnel at the other end so all the marbles collect themselves off the table i think it will save you alot of time in the long run.
this series is awesome. Hard challenge but very entertaining.
3:00 Salfumán, Aluminum foil and a soda bottle. Good memories 😂
Love this project! One suggestion on the exit though. Relying on the inertia of a new ball to push an old one out is a novel idea, but seems to be way more sensitive than it’s worth. I think you should switch to a gate that stops the balls from falling out that is opened to let old ones fall and then closes to catch the new ones coming in.
Don’t try to time it with electronics either, let the new balls coming in trip a lever that spits the old balls out of the way by releasing the gate and puts the gate back so it’s back in place when the new ball gets to the end of the lane. That way, even if the balls aren’t rolling just the right speed, it won’t matter.
Can’t wait to see this work reliably!
Also, for the love of all that is holy, put that thing on a box and let the balls fall into the tub! Stop chasing them all over the table and floor! 😂😂🙃
¡Menuda paciencia tienes! =)
En ascuas me tienes esperando a ver como acaba la cosa. 👍
So glad you are making "science experiments" 😂
I wonder if the sudden issues are caused by introducing black marbles. It looks like the acid-finished surface of the black marbles is way rougher than the chromed ones, which probably introduces a lot of friction that wasn't there when you were testing with only chromed marbles.
That's where I'd put my bet too
Wow; that looks like such a frustrating project, but I'm sure you're learning a lot and at least you have some good content for TH-cam. Thanks for the entertaining video!
"The power of Lazy - Unstoppable!" needs to be a shirt or sticker!
I dont know how you stay so calm
You are such a mad lad, I just absolutely love it
The most patient man in the world!
Gratuluję przede wszystkim cierpliwości przy budowie tego zegara!
