I love this idea, but I can't help but thinking that breaking it down into individual digits that change vertically downward would make it slightly easier. Have a nozzle of marbles that deposits the right amount of each color into a buffer, release the lower number from the 'display', release the upper number down to that in the 'display,' repeat. Still a herculean effort but you have more time to prepare the display, and more help from gravity in advancing it
You don't even need a buffer that sorts marbles. If the modules are vertical, you can just leave the marbles preset for all 10 digits and have a way to store them in that order. No sorting or complex robotics required
Bold move for making the display horizontal. I would've thought a vertical display would be easier so you could drop the segments individually instead of all together.

Your ingenuity and skills are inspirational - please continue making things and sharing the highs and lows.
It probably wasn't easy 50 years ago. Now, I think that an ordinary LED, a photoresistor and a microcontroller may be enough, but I'm curious how it will be solved :)
I'm sensing either a camera based system or photo-sensor to detect black from white and eject the 'incorrect' marbles as they ascend the lifter. OFC that would need some pretty extensive programing to know what marble needs to be where in the 'display' raceway. I've seen videos of industrial sorting machines doing this with air nozzles to kick out - for instance - bad product from ripe product in sorting lines at hundreds of frames per second, ejecting 'dross' so fast it takes a high speed camera to detect it.
@@justinc2633have the marble roll through a shroud where a led shines on it and a photoresistor catches the light reflected off the marble. Hook up the photoresistor as a voltage divider (needs another resistor, but that is usually built-in to the microcontroller) to an ADC capable microcontroller to sense the changes in resistance/voltage/light. Measure the amount of light reflected for marbles of both colors to determine a good cutoff value.

If something about my explanation is unclear, please let me know in a reply so I can amend or supplement it.
instead of the resistor, use a photodiode because it's faster. shine the led onto the marble and with the photodiode you can measure the amount of light the marble reflects. If it reflects a lot of light, it's white and if it reflects not much light it's black. With this info you can trigger a "pusher" of some sort to put the marble which is currently passing through the sensor into different containers. @@justinc2633
That will be quite the challenge, indeed. Only manner I could see that working is having gates or pins to limit what color will enter each hole at what time. Using metal and magnets would be far too heavy. Or, like the ejector assembly at the top, have one just above the input to 'eject' the wrong colors back down into the loading platter.
Eject the bad ones while climbing seem to be the simpler to implement. Color reader sensor, solenoid and the pins to eject 🎉 add a capture track to merge them back at the bottom and that is it. 😅

@@testman9541yeah this is the way it's gonna be done. Marbles are quite shiny though so calibrating the sensors could prove to be a bit tricky. Black and white is just a difference in sensitivity, but shiny black marbles detected at the highest point in the marble will reflect as much light as white marbles at the edges. Moving the sensor a bit further away to average out each marble is probably the way to go. And only rejecting white marbles will make things easier. One sensor rejects white marbles and another counts black marbles is probably the most stable way of doing it.

Can't wait to see how you separate the marbles by color. I think a clock that updates every 5-10 minutes would be impressive let alone every minute.

Seems like an oversight to not have made the marbles drop vertically so you could have only flushed the minutes, 10 minute and hour marbles as necessary rather than resetting the WHOLE display every time.

@@ivanmirandawastaken I'll reserve my judgement for when I figure out how you're going to determine which color goes where and whether you can do it within 60 seconds! 😁

Your dedication and engineering is top class. Thanks for showing us and I cant wait to see the progression.
Winter gartan had lots of headaches with marbles and has a lot of great solutions. You should have some vertical tubes that the marbles run over, and an adruiono that selects if the tube should open and let the marble drop, based on the color needed.
Just the shots needed for the video and the stitching and editing I imagine took weeks. The design and thought going into the machine itself? I can't imagine. Can't wait for the next parts.
Iḿ very much wondering how you wil lget the marbles in the right order to display the next time, mybe just bypassing unfitting marbles in each row when they come towards the display section. could be done with a simple light sensor (like the line follower bots) and an arduino that keeps track of which marble is needed....sounds like a nightmare to code...
Thermochromic paint them all. Pre-chamber with a grid of heaters that warm up the time ones. No sorting required, just some thought about control circuits. They’ll have cooled back down by the time they’ve climbed the lift. Possibly run them through a water bath on the way back. Might allow for 1min updates. Actually closer to an LCD than having different colour marbles.
As someone that's watchinh since the begining of Wintergatan X... This dude is on for a LOOOONG ride (also getting on the same pitfalls as you is kinda painfull)
Let the marbles hit the floor, let the marbles hit the floor, LET THE MARBLES HIT THE FLOOOOOOR. Sorry, I'm better now. This looks super fun! Can't wait to see how you sort white from black to get the numbers to display properly. Thanks for sharing!
Why not have the tracks on the display release vertically? Then you could selectively release each digit - the time changes every minute, but some of the digits only need changing every 10 min or hour.
can't wait to see it working. 1 thing that came up in my mind is that if you let the Mable display change vertically, you would be able to change the numbers individually. Then at the hour change, there would be a lot more noise/action. however, for the show/action, horizontally is most likely more fun
If you adjust the channels vertically, you can easily track and measure changes in individual time increments. You can account for the units of seconds, then the decades of seconds, then the hours, and finally, the decades of hours :)
To make the time you need to control what marbles go where. Im very curious how you are going to to that. Maybe you should add a sort step inbetween to sort blacks and whites buffer the time rom there to the release the time to the final position every minute.
I have two suggestions for you: 1_ use metallic marbles ( it's They are all the same size and very smooth and do not create such a rough surface like glass marbles, then just paint it in white and black) 2_ Use Dry lubricants like graphite and molybdenum disulfide on the threads or paths , it will make your marbles traffic very smooth.
Awesome project! To stop the marbles jumping out of the bottom tray, how about narrowing the exit from the "covered" section. I.e. if the exit gate is only 1.2-1.5 marbles high then they won't jump out as easily. Now for the elephant in the room, how are you planning to sort the marbles before building up the time display? Might I suggest switching to steel and ceramic ball bearings? This would give you 3 easy ways to sort the marbles and the marbles would all be a uniform size. (weight, magnetism, and conductivity)
I think he is going to reject unwanted colour marbles from the elevator by using maybe a set of simple infrared detectors and popping them off the elevator ,back down to the collection area as they rise.
@@JohnWatkinsUK that's a great idea. Didn't think of it initially as it's not very efficient. But it's lots simpler and should get the job done as long as he can cycle enough marbles past the selectors.
Steel bearings and magnets would be far too heavy for that frame. I suspect he'll go with what @JohnWatkinsUK said, using low-res sensors rather than infrared - detecting only black and white. That'll cut down on the glossy-error issues.
@@JohnWatkinsUK would an infrared sensor be consistent enough? and hows he going to eject them? i thought maybe replacing the little fingers that poke them out of the elevator with individually controlled ones using servos, eject white, let the black fall into their own track, and to load them back up each row would need access to both colours, thats a whole other thing though
Great project idea but you're going to run into a problem with the marble bias at the end, most of the marbles want to end up in the far right corner, which affects which gate they come out of on top. Additionally you need a sorting mechanism between black and white marbles, or else your clocks activity will be entirely dependent upon your total supply of black and white marbles. Not only the sorting mechanism but a stacking mechanism that picks and chooses where black and white marbles go into each channel to display the numbers you want to see. Of course all of this would have to occur within 60 second intervals so that you have hour and minute time scale. Although not an immediate problem, the mechanism for popping the marbles out of the lifter is rubbing on the backside of the lift belt, short term this is fine but long term either the popper will rub down and no longer be effective, break, or even wear grooves into the backside of the belt which may affect operation. It's a super cool clock idea but a bit of a mechanical nightmare to employ. Ironically I'd argue that you don't have to worry too much about your tolerances for the marble gates and paths and the marbles themselves, you spent a colossal amount of time making it all so precise when you could've designed around the marble size being inconsistent, in the belt the size matters more but a design change could mitigate that too, just a thought as far as overloading yourself with work goes.
Funny how a full display of the four segments is 13x31 marbles. That's 403 marbles every minute. Roughly 7 per second. With a marble lift 13 wide that seems to run about 1 step a second, I guess at least the marble lift is fast enough (with not picking up always in all holes). This certainly is going to be a loud clock...
Only just stumbled across your channel through a watch group I'm in... this is such a good episode!! Love your approach, humour, and how down-to-earth you are. Brilliant build, very entertaining to watch, and genuinely hilarious. Keep up the awesome work! Much love from down under 🇦🇺
You seem to have found a real sweet spot! There are hordes of builders doing incredible craftsmanship with welds, machining,… and tons of tech savvy folks doing raspberry Pi etc., you provide an enlightening I’d. thanks
What a fun, weird project. Personally I think you like the chaos of all those marbles hitting the floor. I’m dubious that you could make that a feature of the final machine, so enjoy it while you can!
Design concepts that use 3D printing for something that would be super, super hard to fabricate by other means are the _best_ concepts. Fantastic stuff!
First I thought "why doesn't he just let the marbles roll out of the marble lift on the other side?" But after seeing - and hearing - the marble dismount mechanism in action, I see the reason. I absolutely love how it ticks like a clockwork.
If you thought the •tick•tick•tick• of a normal clock was annoying... Seriously, this is such an inspired alternative to the traditional marble clock. Looking forward to the final finished horologe!
So you kind of solved the easy part. Now the more difficult part to sort the marbles by color and the really difficult part to rearrange them perfectly and in time, so that they show the correct time the moment they roll into the display area. Good luck! Little hint, if you have a huge difficult problem: Chop it up and start with the difficult part or you might need to completely redo the easy part of the solution multiple times.
I see a lot of comments mentioning how each digit should be vertical, so you only have to change one at a time instead of all four - but guys, that would be logical and easier! this is Ivan! when has he ever let silly likngs like that stop him? :D He actually lost his marbles this time, I love this channel.
9:52 - I think it would be a much better long-term approach to bend that track forward on a wheel that will make that track follow the s like patterm and will also push the marbles out consistently, without jitter or parts that will wear out quickly
The marble selection *should* be easy enough simple black/white detector (either an Ir reflector sensor or maybe an Adafruit APDS9960) Paired with an arduino. Have a solenoid to reject wrong colors in the path on the belt before it gets to the top. Rejected marbles just fall back down to the bottom. should be realtime enough. Once the correct Number of marbles are loaded for the next minute load for the minute after that. Once the count and cadence is correct should be close to real time. Hope this helps cant wait to see what you come up with.
I’m a 65 year old woman with zero skills that require more than a hammer or screwdriver. But I was fascinated by your tenacity. Can’t wait for Pt 2. Can’t even imagine how you’re going to make this work. But I have faith that it will happen. Got a new subscriber here. Build on. 😊
Here's an idea. Use a PV sensor to select white from black and a solenoid to kick one of the colors to a different track. Maybe have two layers for the top section and send all the whites to the back. Then you can selectively add them back in at the gate.
@@Yay295 you think? I'd think there would be enough contrast between the white and black. You could use an Arduino to read the voltage VS using it as a dumb switch.
The way I see it is that there are two main ways to separate the colors. Option A: You rebuild the bottom tray to force them to always stay in their correct line(with a ceiling to avoid any marbles jumping to other lines). That lets you keep the marbles in a known order, and a separator drop based on a counting checker for each line would allow for a computer program to pull out the white marbles automatically. Option B: You switch to using magnetic marbles for white ones and non-magnetic for the black ones, and then use a rotating magnet to pull out all of the white marbles and deposit them in another tray.

I love how right at the end he mentions how he had to reprint the mesh cap to prevent the marvels to jump out the machine, and just 1 second before the video ended he had like 10 marvels escaped with the new part installed. So painful.
If you had a camera watching the marble feed belt and a set of solenoids controlling the ejection arms for each belt position, you could selectively eject one marble color from the belt a step earlier than the full eject. I think the key to building the clock "face" is separating the marble chaos.
Fukineh! Beautiful work buddy. The "it works" realization is priceless. I literally lol. Hilarious. You are so smart even when some silly thing like that happens. Thanks! Cheers!
some nuggets for thought: 1) ball bearings are more reliably measured and round (and durable), come in multiple materials like steel and brass, and you can impart color to steel ones with an oven or kiln (or blow torch) as well as being magnetic*, AND coming in 1mm increments (or less) for precise engineering (plus they're not TOO expensive) 2) if you have 2 colors of ball that're also different sizes, they can be sorted by holes for easier differentiation, but they need to be precise (so ball bearings may be better for that, again) 3) okay, I really didn't mean to just be advocating for ball bearings here, but you could also eschew separating different balls altogether by having strong magnets on the tips of solenoid rods acting as pixels, extended in sequence, they'd capture bearing balls in place to display the number, you wouldn't have to have multiple types of ball and could have far few balls for each image and therefore could make the sculptural elements more fun since you wouldn't need such a high volume of ball movement.
I can't even think of any ideas how you're actually going to sort the marbles to actually show the time instead of just being a cool marble raceway, definitely looking forward to what you do with this project.
To avoid the weight of the marbles pushing out the solenoid, turn the marble tracks into buffer regions. Since the selection process still needs to be designed, the elevator can be part of it and reject marbles by pushing them into another track going back to the bottom. The first buffer builds up the time being selected in the elevator, a second buffer holds the next time to be displayed in the curve, and the last buffer holds the current time.
*@Ivan Miranda* 13:55 That's why you should not build the next minute in the bend-section, but instead on the straight section above, so you have MUCH less force on each marble & on the gate. PS. Check out the channel: *_Vintergatan_* & his videos about his different *_Marble machines_* lots to learn there.
Without wanting to influence your design, I think pushing marbles out of the lift and recycle them is the simplest way of sorting them. But this means some randomness to things, and lift needs to be fast enough to be able to reject a lot of marbels and still form the next minute in under a minute. On the rejection side and dump side, all marbels could go to the left, mainly for a bigger hopper and more chaos. Right now all marbles gather in one corner at the lift. Also insteag of a gate for the next minute, you could use a sprocket like thing to count the marbels, and make sure only a certain amount passes trough. Second idea would be to have a multiple stage rejection system. In reverse / descending order, stage 3 rejects all wrong marbels, stage 2 rejects all white marbels and pushes them in a new hopper only for white above the stage 1 that may push out black marbels to make room for a white one in the above white only hopper. Complicated but sorting should be faster.
Good luck! Really looking forward to watching "BUILDING A MARBLE CLOCK - Pt.196: MAYBE WE CAN INCLUDE SECONDS AFTER ALL?? (DESIGN EXPLODES AGAIN)" in a few years! :P
I’m not sure what colours you can get them in, but using steel marbles rather than glass ones would probably result in more consistent sizes between them as well as less bad ones.
I once had this marble clock, I went crazy by the noise... Especially at 12 o clock. This is that times 100 haha. But kudo's to your skills and persistence!
After watching Martin trying to build the MMX for several years, I wonder what world of pain we're about to see unfold here.
Feature creep + undefined goals are a hell of a drug
Man it seemed so close and easy when meeting him with the first 3D printed MMX prototype parts in May 2017 at the Speelklok Museum
Unfortunately Martin can't stop feature creep from getting into the project
Difference being that Ivan has more of an engineering mindset, that likely helps. I also don't see him find inspiration, direction-wise, in questionable books. :)

He’s trying to make it work the simplest way possible, its meant to be a challenge.
That was my thought too, it seems like it would be simpler to only change 1 number but will be interesting to see finished project
And since the digits are made of pixels, you don't even have to use the seven segment display style. You could use more natural-looking numerals.
Bold move for making the display horizontal. I would've thought a vertical display would be easier so you could drop the segments individually instead of all together.
Looking forward to see how this turns out! Also loving the black filament 😄

As someone that's watchinh since the begining of Wintergatan X... This dude is on for a LOOOONG ride (also getting on the same pitfalls as you is kinda painfull)
Let the marbles hit the floor, let the marbles hit the floor, LET THE MARBLES HIT THE FLOOOOOOR. Sorry, I'm better now. This looks super fun! Can't wait to see how you sort white from black to get the numbers to display properly. Thanks for sharing!
I thought he had been too quiet…. 😂
Edit: STRONGEST BACK IN TH-cam!!
Why not have the tracks on the display release vertically? Then you could selectively release each digit - the time changes every minute, but some of the digits only need changing every 10 min or hour.
Amazing project Ivan! 🤘😎🤘
can't wait to see the future updates!
can't wait to see it working.
1 thing that came up in my mind is that if you let the Mable display change vertically, you would be able to change the numbers individually.
Then at the hour change, there would be a lot more noise/action.
however, for the show/action, horizontally is most likely more fun
If you adjust the channels vertically, you can easily track and measure changes in individual time increments. You can account for the units of seconds, then the decades of seconds, then the hours, and finally, the decades of hours :)
To make the time you need to control what marbles go where. Im very curious how you are going to to that. Maybe you should add a sort step inbetween to sort blacks and whites buffer the time rom there to the release the time to the final position every minute.
"Hourglass style clock doesn't work with marbles, how do we tell the time?" Ivan: "Hold my beer."
You kmow I'm not easily disuaded 😅
I have two suggestions for you: 1_ use metallic marbles ( it's They are all the same size and very smooth and do not create such a rough surface like glass marbles, then just paint it in white and black)
2_ Use Dry lubricants like graphite and molybdenum disulfide on the threads or paths , it will make your marbles traffic very smooth.
If you heat up the bearings to red hot, they turn blue and stay that way.
Awesome project! To stop the marbles jumping out of the bottom tray, how about narrowing the exit from the "covered" section. I.e. if the exit gate is only 1.2-1.5 marbles high then they won't jump out as easily.
Now for the elephant in the room, how are you planning to sort the marbles before building up the time display? Might I suggest switching to steel and ceramic ball bearings? This would give you 3 easy ways to sort the marbles and the marbles would all be a uniform size. (weight, magnetism, and conductivity)
I think he is going to reject unwanted colour marbles from the elevator by using maybe a set of simple infrared detectors and popping them off the elevator ,back down to the collection area as they rise.
@@JohnWatkinsUK that's a great idea. Didn't think of it initially as it's not very efficient. But it's lots simpler and should get the job done as long as he can cycle enough marbles past the selectors.
@@JohnWatkinsUK Infrared/color detectors often have issues with shiny materials though, and his current marbles are made of glass.
Steel bearings and magnets would be far too heavy for that frame.
I suspect he'll go with what @JohnWatkinsUK said, using low-res sensors rather than infrared - detecting only black and white. That'll cut down on the glossy-error issues.
@@JohnWatkinsUK would an infrared sensor be consistent enough? and hows he going to eject them? i thought maybe replacing the little fingers that poke them out of the elevator with individually controlled ones using servos, eject white, let the black fall into their own track, and to load them back up each row would need access to both colours, thats a whole other thing though
"It's only a small marble clock. How hard can it be?"
*Wintergatan screaming from a distance*
Great project idea but you're going to run into a problem with the marble bias at the end, most of the marbles want to end up in the far right corner, which affects which gate they come out of on top. Additionally you need a sorting mechanism between black and white marbles, or else your clocks activity will be entirely dependent upon your total supply of black and white marbles. Not only the sorting mechanism but a stacking mechanism that picks and chooses where black and white marbles go into each channel to display the numbers you want to see. Of course all of this would have to occur within 60 second intervals so that you have hour and minute time scale. Although not an immediate problem, the mechanism for popping the marbles out of the lifter is rubbing on the backside of the lift belt, short term this is fine but long term either the popper will rub down and no longer be effective, break, or even wear grooves into the backside of the belt which may affect operation. It's a super cool clock idea but a bit of a mechanical nightmare to employ. Ironically I'd argue that you don't have to worry too much about your tolerances for the marble gates and paths and the marbles themselves, you spent a colossal amount of time making it all so precise when you could've designed around the marble size being inconsistent, in the belt the size matters more but a design change could mitigate that too, just a thought as far as overloading yourself with work goes.
Funny how a full display of the four segments is 13x31 marbles. That's 403 marbles every minute. Roughly 7 per second.
With a marble lift 13 wide that seems to run about 1 step a second, I guess at least the marble lift is fast enough (with not picking up always in all holes).
This certainly is going to be a loud clock...
I love how you make design insanity a new normal!
Martin sadly put on a very public seminar of how to slowly lose your marbles by getting lost in trying to build the impossible.
Impresionante! Podrías girar 90 grados las pistas para descartar solo las bolas de los minutos con cada cambio de minuto. Esperando el siguiente!
But… can it play music?
Wintergaten issues.
"Tight " music
Your joy and enthusiasm is contagious
Ivan, me fascina como consigues todo esto. La expansion de tu canal es 100% merecida. Suerte en el futuro!
Hi Ivan,
das ist wohl daß absolut Coolste Projekt was ich bis jetzt als 3D Druck gesehen habe!
This looks super cool! Thank´s for your amazing content 💜
I like that he just continuously lets marbles fall onto the floor
But... ITS NOT RED!!
Watching those marbles fall down only to get scooped up and dropped again, one must imagine Sisyphus happy.
Only just stumbled across your channel through a watch group I'm in... this is such a good episode!! Love your approach, humour, and how down-to-earth you are. Brilliant build, very entertaining to watch, and genuinely hilarious. Keep up the awesome work! Much love from down under 🇦🇺
You seem to have found a real sweet spot! There are hordes of builders doing incredible craftsmanship with welds, machining,… and tons of tech savvy folks doing raspberry Pi etc., you provide an enlightening I’d. thanks
At least I might be able to see the end result of this project unlike the MMX
I'm not whether you'r a genius or just crazy. Maybe a bit of both, but I love it. Can't wait to see Part 2
What a fun, weird project. Personally I think you like the chaos of all those marbles hitting the floor. I’m dubious that you could make that a feature of the final machine, so enjoy it while you can!
Design concepts that use 3D printing for something that would be super, super hard to fabricate by other means are the _best_ concepts. Fantastic stuff!
Wouldn't making the channels vertical mean you could only cycle the changing digits instead of the whole display?
First I thought "why doesn't he just let the marbles roll out of the marble lift on the other side?" But after seeing - and hearing - the marble dismount mechanism in action, I see the reason. I absolutely love how it ticks like a clockwork.
El acento español es inconfundible 😂
Maravilloso vídeo! Love the idea
If you thought the •tick•tick•tick• of a normal clock was annoying... Seriously, this is such an inspired alternative to the traditional marble clock. Looking forward to the final finished horologe!
Why use horizontal channels instead of vertical ones? The second option would only require changing the last minute most of the time
I like just listening to this guy talk. He sounds so positive.
So you kind of solved the easy part. Now the more difficult part to sort the marbles by color and the really difficult part to rearrange them perfectly and in time, so that they show the correct time the moment they roll into the display area. Good luck! Little hint, if you have a huge difficult problem: Chop it up and start with the difficult part or you might need to completely redo the easy part of the solution multiple times.
I see a lot of comments mentioning how each digit should be vertical, so you only have to change one at a time instead of all four - but guys, that would be logical and easier! this is Ivan! when has he ever let silly likngs like that stop him? :D
He actually lost his marbles this time, I love this channel.
Thanks!
That’s pretty cool!
発想が面白い🤣 頑張ってくれ😊
Original, silencioso y portable, jejeje. Miranda, eres un crack
9:52 - I think it would be a much better long-term approach to bend that track forward on a wheel that will make that track follow the s like patterm and will also push the marbles out consistently, without jitter or parts that will wear out quickly
Wintergatan PTSD just kicked in
The marble selection *should* be easy enough simple black/white detector (either an Ir reflector sensor or maybe an Adafruit APDS9960) Paired with an arduino. Have a solenoid to reject wrong colors in the path on the belt before it gets to the top. Rejected marbles just fall back down to the bottom. should be realtime enough. Once the correct Number of marbles are loaded for the next minute load for the minute after that. Once the count and cadence is correct should be close to real time. Hope this helps cant wait to see what you come up with.
I’m a 65 year old woman with zero skills that require more than a hammer or screwdriver. But I was fascinated by your tenacity. Can’t wait for Pt 2. Can’t even imagine how you’re going to make this work. But I have faith that it will happen. Got a new subscriber here. Build on. 😊
Niesamowita konstrukcja. Lubię oglądać konstrukcje domowej roboty
These just keep getting better and better.
Here's an idea. Use a PV sensor to select white from black and a solenoid to kick one of the colors to a different track. Maybe have two layers for the top section and send all the whites to the back. Then you can selectively add them back in at the gate.
A pv sensor might have trouble with the shiny glass marbles.
@@Yay295 you think? I'd think there would be enough contrast between the white and black. You could use an Arduino to read the voltage VS using it as a dumb switch.
Can't wait for part 167
The way I see it is that there are two main ways to separate the colors.
Option A: You rebuild the bottom tray to force them to always stay in their correct line(with a ceiling to avoid any marbles jumping to other lines). That lets you keep the marbles in a known order, and a separator drop based on a counting checker for each line would allow for a computer program to pull out the white marbles automatically.
Option B: You switch to using magnetic marbles for white ones and non-magnetic for the black ones, and then use a rotating magnet to pull out all of the white marbles and deposit them in another tray.
I love how right at the end he mentions how he had to reprint the mesh cap to prevent the marvels to jump out the machine, and just 1 second before the video ended he had like 10 marvels escaped with the new part installed. So painful.
If you had a camera watching the marble feed belt and a set of solenoids controlling the ejection arms for each belt position, you could selectively eject one marble color from the belt a step earlier than the full eject. I think the key to building the clock "face" is separating the marble chaos.
15:08 WOW, just WOW! Can't wait for the next video on this most impressive task.
The lenghts some people are ready to go to just not having to read an analog Clock.
Great projekt ;)
I have the feeling he's not accounting for the fact that he needs to separate the marbles by color after they go through the slide.
Oh no! We can not lose another great TH-camr to the marbles!
Suggestion: Put the marbles in a tumbler for 2 hours. This will smoothen the surfaces even more.
Nice project!
You should 3D print your own marbles!
Fukineh! Beautiful work buddy. The "it works" realization is priceless. I literally lol. Hilarious. You are so smart even when some silly thing like that happens. Thanks! Cheers!
some nuggets for thought:
1) ball bearings are more reliably measured and round (and durable), come in multiple materials like steel and brass, and you can impart color to steel ones with an oven or kiln (or blow torch) as well as being magnetic*, AND coming in 1mm increments (or less) for precise engineering (plus they're not TOO expensive)
2) if you have 2 colors of ball that're also different sizes, they can be sorted by holes for easier differentiation, but they need to be precise (so ball bearings may be better for that, again)
3) okay, I really didn't mean to just be advocating for ball bearings here, but you could also eschew separating different balls altogether by having strong magnets on the tips of solenoid rods acting as pixels, extended in sequence, they'd capture bearing balls in place to display the number, you wouldn't have to have multiple types of ball and could have far few balls for each image and therefore could make the sculptural elements more fun since you wouldn't need such a high volume of ball movement.
there's something satisfying about watching Ivan Miranda build.
oh boy, that pause at 6:03 was really funny, great work!
I can't even think of any ideas how you're actually going to sort the marbles to actually show the time instead of just being a cool marble raceway, definitely looking forward to what you do with this project.
this is probably the most realistic diy video ive ever seen, the guy listens to music while he is working, you just dont see that anywhere else
To avoid the weight of the marbles pushing out the solenoid, turn the marble tracks into buffer regions. Since the selection process still needs to be designed, the elevator can be part of it and reject marbles by pushing them into another track going back to the bottom. The first buffer builds up the time being selected in the elevator, a second buffer holds the next time to be displayed in the curve, and the last buffer holds the current time.
*@Ivan Miranda*
13:55 That's why you should not build the next minute in the bend-section, but instead on the straight section above, so you have MUCH less force on each marble & on the gate.
PS. Check out the channel: *_Vintergatan_* & his videos about his different *_Marble machines_* lots to learn there.
This would mean that the next time would be displayed upside down. At least on the curve the marbles are incomprehensible
this vid is cool but what i want to know is where he got those marbles
My man you're an absolute genius, good to see people enjoying doing what they love
Setting up the digits befor the lift is the best way in my opinion as it also keeps all the sensors lower to reduce weight
hermano eres de los mas creativos que he visto en siglos
Sir, you make me smile, thank you very, very much
Could also display a QR code with that. Excited to see more.
I guess so, in the end it is just a display right?
Without wanting to influence your design, I think pushing marbles out of the lift and recycle them is the simplest way of sorting them. But this means some randomness to things, and lift needs to be fast enough to be able to reject a lot of marbels and still form the next minute in under a minute.
On the rejection side and dump side, all marbels could go to the left, mainly for a bigger hopper and more chaos. Right now all marbles gather in one corner at the lift.
Also insteag of a gate for the next minute, you could use a sprocket like thing to count the marbels, and make sure only a certain amount passes trough.
Second idea would be to have a multiple stage rejection system. In reverse / descending order, stage 3 rejects all wrong marbels, stage 2 rejects all white marbels and pushes them in a new hopper only for white above the stage 1 that may push out black marbels to make room for a white one in the above white only hopper. Complicated but sorting should be faster.
Good luck! Really looking forward to watching "BUILDING A MARBLE CLOCK - Pt.196: MAYBE WE CAN INCLUDE SECONDS AFTER ALL?? (DESIGN EXPLODES AGAIN)" in a few years! :P
I’m not sure what colours you can get them in, but using steel marbles rather than glass ones would probably result in more consistent sizes between them as well as less bad ones.
I once had this marble clock, I went crazy by the noise... Especially at 12 o clock. This is that times 100 haha. But kudo's to your skills and persistence!
