I swear there’s an evolution of every maker that goes from bodies->gears->linkages->pulleys->cams your ability to combine them is always awesome to watch
Fun fact: Ducati uses a system like this called desmodromic valves on their engine camshafts to eliminate the valve spring and thus preventing valve float at very high rpm
Just put each segment on the tip of a rod attached to a profile groove in a control wheel. As the commin axle turns, the segments are pulled and pushed to show the numbers from 0 to 9 . Now add the gearing to stack the digits into a counter where each digit overflowing turns the next one a single step . Of cause the same used to be done by painting nice looking digits on a wheel .
@@SwordFishTheFish I meant it as an easier way than what he already did, because it's basically skipping a lot of steps, and reusing known techniques used for the same job 50+ years ago . All about making it easier .
My thoughts exactly. You need a single drum with 7 tracks and 7 pointers arranged around it. There wouldn't be much complexity at all. You could even hollow it out and have some pointers on the inside so the whole assembly isn't too deep.
I just remembered. There’s a channel called からクリスト. They have a variety of mechanical seven segment display designs and there’s likely one that suits your needs.
A simpler version would have the seven segments rotate via 7 pins, sitting inside 7 grooves in a circular cam, like a record with 7 squiggly lines in it, and the input part just rotates 360°. As it rotates, the seven pins are pushed into one of two positions.
Interesting mechanism, but a secondary benefit of a spring or elastic return mechanism is that it will take up the backlash in the system, which this approach will not. This might not matter if you can carefully control the cycles and you only care about the final angle in one position (segment visible) but comes up especially when you need to be able to reverse directions and return to the same position.
I feel like this could use some compliant mechanism. You could make the movement of returning using compliant mechanism to use the elaetic properties of the plastic. So you have a moving part printed in one single part.
Pairing this with a Geneva gear could allow you to actually hook this up to a 3d printed clock spring based clock. Allowing it to be completely 3D printed.
That's clever. Some engine manufacturer should look at that for their intake and exhaust valves. Maybe on a high performance engine, like a motorcycle. Maybe *Ducati* would try it?
This short was right after another that showed an animation of a pawn transforming into a queen. It makes me wonder if that too would be possible IRL.....
It's frustrating that you can see a small part of the segments that are supposed to be invisible. Maybe you can print them in two colors with white on the front and black on the side/back so it's Invisible when turned away? Very cool though, excited to see where the project is headed
Put that thing inside the water and see if it starts releasing bubbles then that means you can still shrink it. Keep repeating until You see no more bubbles 👍
Just bought the A1 bamboo printer. This is definitely gonna be one of the projects I’m gonna print. Edit and learn how to do electronics for adjust this lol
love the idea but wouldn't you have a much simpler and compact system with a peg through an eccentric hole pushing a rod? feels like this got over complicated, especially with the gear. will you be resin printing later for smaller pack size? Great work still!
Is this the best way to do a in and out circular to linear motion transfer? I feel like an alternating gear system or piston style pushing system with kan rod and stuff would have less friction? But maybe would require a different frame size or more moving parts, not sure.
But you don't need any of that if you simply rotate a magnet and have another magnet on the segment! When the magnets attract, the segment is in one position, when they repel, it'll snap to the other position! Easy! The best part is no part...
@@autodystopia same as any motion is smoothed, a little friction; or with oil and a small hole, like a damper in vehicle suspension; or possibly with a gear and air resistance like a musical box. Personally I would keep it simple and instantaneously switch like an LED/LCD display does normally!
@@kaleygoode1681 > Personally I would keep it simple and instantaneously switch That's it. I would have preferred the segments to switch slowly, like in a video. And this won't work with magnets.

Why do you need the bottom cam, can’t the top cam be designed to both move the front follower forward and then hit a backside follower that moves the rig backwards ?

As someone who is new to this, I’m ready to go from bodies to gears 😂😂, but screenshotting your comment so I know what comes down the line
"goes from BODIES to GEARS".....should I ask?
Its not specific to makers that is engineering
Cams are the real deal when it comes to mechanical design!
@masonmakesstuff might as well ask here - any great resources on gears - Especially as used in making?
This is so impressive. The animation of the 7-segment display is a nice touch too
Hopefully will be IRL soon!
Ducati uses a similar mechanism to move the valves in their motorcycle engines! They call it Desmodromic
The originality of their valvetrain is what made me love Ducati.
Mercedes did too
I came here to say the same haha
So they don’t need valve return springs?
@@moneyshifters they still need them at the very least to hold the valves close
Look at the Ducati 'Desmodromic' valve mechanism.
You need to look up the Benz desmodromic valve. From 1889
@@johnantonopoulous6381you need to look up the DaVinci desmodromic paint brush from 1482.

I’m gonna do my best to keep em coming!
I can literally smell the friction.
literally?
Well, at least you’re literate. That’s good
I just remembered. There’s a channel called からクリスト. They have a variety of mechanical seven segment display designs and there’s likely one that suits your needs.
🙏🙏
Judging by that cad animation at the end I would probably say you already know how to stack seven of them
This reminds me of an old mechanical scoreboard I got to take a look at, with a servo motor controlling every segment of every digit. 42 servos.
Love it can’t wait to see this integrated into the final product!
Coming soon!
You should make a mechanical clock with a digital display 😂
Might have to!
_We spent so much time wondering if we could, that we forgot to ask if we should_
Digital clocks with mechanical displays are all the rage, wait’ll they get a load of this!!
A wind-up digital clock! 😄
I'm still working on my own clock after seeing your video. Your stuff is so sick man.
Above forty years ago gas stations had that kind of segmented numbers that went around in a circular pattern.
Was fascinating to watch.
A simpler version would have the seven segments rotate via 7 pins, sitting inside 7 grooves in a circular cam, like a record with 7 squiggly lines in it, and the input part just rotates 360°. As it rotates, the seven pins are pushed into one of two positions.
This dude is the embodiment of perpetual persistence and I commend it 😊
technology brought us to places where things can and are done easily, this dudes just trying to go back in time!! USING NEW TECHNOLOGY, HOW AWESOME!!
That is incredible!! It can absolutely be done. A _ton_ of complex work, but I'm rooting for you.
It's almost a distribuzione desmodromica
Kind of looks like a miniature rotary engine, basically the same concept.

This might not matter if you can carefully control the cycles and you only care about the final angle in one position (segment visible) but comes up especially when you need to be able to reverse directions and return to the same position.
It’s beautiful!
Thank you. Awesome.
Awesome work. Hopefully it all comes together as you hope.

My mind immediately went to Desmodromic system and made my heart skip a beat 😂
Wow that’s really cool

Thanks❤❤
Watching this reminds me of desmodromic valve actuation
I think that's a similar idea to what Ducati did in some of their bikes where they were able to get rid of valve springs.
Use it in a Pinball machine, combined with that ball-activated Geneva mechanism.
Awesome idea without spring, looking forward to see the project... kudos...
Thanks! 👍
This looks awesome!
I wonder what kinds of optimizations still lurk around.
This short was right after another that showed an animation of a pawn transforming into a queen. It makes me wonder if that too would be possible IRL.....
looking forward to this clock design
It won’t stay open after it breaks in if the cam is being lifted vertically and vibration will add additional complications
Clever stuff!
bro was casually slamming JPBlink
cool stuff!
Cool 😎
Thanks!
Ducatti did a version of this they called it desmo valves it allows them to rev really high even by motorcycle standards with out floating a valve
Is huge, for such a small (and possibly light) load.
I must have one!!!!
Amazing!!!
super cool
That's what I'm talking about!
That rack and pinion could probably just be a two bar link like the type at the end of excavator arms
U could easily condense that down, theres a lot of unused empty space there
Ducati :"first time?"
The inside white part of the numbers could be printed in a glow in the dark filament! That would look nice!
True!
"Look Mum No Computer" just did 2 videos on similar, VERY OLD versions of this display
i love your videos!! always so fascinating [and making me regret not choosing dt for my gcse]
Thanks used to be JQ!!
@@Engineezy i actually prefer to either be called Luka or Lexie now 😅
And ‘equal diameter’ cam wheel would not require a spring, I think
reminds me of Desmo valves
I can't wait for simracing enthusiast to climb over each other for the chance to get one of theese as a gear indicator using an arduino
Can someone explain this in layman's terms? And why anyone would need this mechanism? And why it's better than other mechanisms for the same purpose?
very nice.
Bro is cooking desmodromic valves
Almost reminds me of a 13B rotary engine in an RX-7
Amazing......as per usual
Thank you so much 😀
Just say “as usual.” You don’t need “per.”
Cool... Izziss how those confetti displays work? A little ornate for just a pixel

I know Ducati uses something similar but my brain just went to thinking about how hooligans might use something similar to hide their plates lolol
Desmodronic clock! It should be Ducati red!😂❤
I was just about to ask, this looks a lot like the desmodromic system for springless valve control.
But you don't need any of that if you simply rotate a magnet and have another magnet on the segment!

yes, it is called a desmodromic cam mechanism
These are my favorite kinds of shorts, actually feels like I learn something from it repeating a few times
Make the Decimal Point.
You should then aim to make the alpha numeric ones... I think 15 segment display or something

Can someone exxplain why you couldnt just use a gear to move it?
