A potential feature idea is to have carryover output/input so you could chain them.
I was just about to suggest the same. Excellent design thus far!
Maybe the plunger could be split, so that it only activated the rachets if 'activated' from the side (ie lower digit carry).
Make it like the Burroughs mathematical machine ruclips.net/video/fe-9uTVMQlo/видео.htmlsi=IJKJGkil5CPoZzBd
The mechanical losses are already pretty big... Having to also actuate another one might end up being either REALLY stiff to press, or even break something... But idk! It would be cool to see regardless.
@@Internetzspacezshipz the lever could actuate all 7-segment assemblies simultaneously and the carry over mechanism could act like a clutch. the force will indeed be greater when going over several orders of magnitude.
Finally a handheld way to count to ten
I've been waiting so long
One handed though, so it improves upon the technology of the hand
That has to be the best project ive seen for a long time - bravo. Tempted to make a clock using steppers with it
Why use steppers when you can use a single motor and gears.
@@Kihidokidstepper motors can be controlled precisely so they always spin at an exact speed, the only control you have over the speed of normal DC motors is the voltage that you put into them (and even then, any amount of load will make them go out of time)
@@skmgeek You could use a DC motor on a cam and a limit switch, with an Arduino counting the time.
@@skmgeek just use a 4rpm motor, input 120v and a small transformer. If you use 4 stepper motors you have to write code. For a clock. You have to use a complicated piece of machinery that has a clock in it to build a clock.
@@soundspark why do you people want to use Arduino in everything. Stop it. You're building a clock using a clock.
One thing that's cool about this is that it could be built in any time period in history, if the correct shapes were known, and yet it feels so electronic and digitally driven. Most of our technology requires usage of a long list of previously created tech
Love this comment
Compliant springs in place of the bands and a way to link multiple together would be fantastic upgrades. Great project, thanks for sharing! :)
Mechanical engineering making a comeback of note.
I agree! Despite being an electrical engineer, my true passion is in mechanical engineering.
Great gift you have. Electrical engineering is a fantastic combination to widen what you can do in mechanical engineering. Particularly in your case. Be blessed.
Can be argued as being a bit big and clunky, but this is rather driven by the limitations of the 3D printing and associated materials.
The design, however, is absolutely exquisite in its elegance and I truly love it. Masterful !!!!
I printed this for my numbers-obsessed kid, and he loves it - he was very excited to help me put it together! And thanks for adding the printed screws, saved me a trip to the hardware store.
This is a super impressive project considering that the only non-3d printed things needed are rubber bands and a couple screws. You could probably even design it to be held together without screws. Super impressive. Well done.
Detents printed into the body components, especially within the stand-off structure, to hold it together.
Printed springs for the push-action return and for each individual segment, a lot more fiddly and might require expanding the body.
Yeah, all of it could be printed in some way for sure.
Or 3D print the screws
What a beautiful design! Assembly so satisfying that I am going to print this, assemble it and then take it apart and give the parts as a present.
Your video serves as the assembly guide.
Given how simplistic the mechanism is, this could very well be shrunken into a very slick mechanical watch. Would LOVE something like this on my wrist.
Wow yes that would be impressive. We have come full circle.
Iove it how 3d printers put design in the hands of so many.
I love this design a lot! A lot of these highly complex models are insanely difficult to assemble but this is poka yoke heaven! Product design mastermind.
Thank you very much!

5:38 - For your next update, you could print each stack as one part so you don't have to bother with gluing them together.
I design, build and fly radio control airplanes as a hobby. As a designer, I appricate how much work you've put in your project. Job well done and 2 thumbs up !!
Wow! I love this, thank you for making the files available for all of us. I immediately thought of using it to make a counter for our sports match, which is currently made out of paper and no one wants to go there and turn the number after a goal. With this tactile feedback, I wouldn't be afraid of it. xD
So I basically need to connect two double counters together!
Thank you for sharing this and making the files available. Very well designed and explained. Great for helping my grandchildren to count!
Pretty impressive! Purely mechanical projects are so satisfying.
You are an amazing person for giving this model out for free. I wish you 20 million subscribers and all the wealth in the world. Have a nice day!
I think the design of this product is very beautiful, this is how products should be made. Pragmatic and reparable
i am happy I landed on the good side on RUclips. Subscribed. What you have given me is ...food for thought. I may or may not attempt this...but there are many things I learnt from this video. Thanks a bunch!
Thank you a lot. This is going to be my 1st project of 3D print as this is so greatly designed and step-by-step guide.😊
Im printing 2 of the 2 segment versions for a competition im holding. THANK YOU!
I am not sure why anyone would want something like this, but it is very interesting.
Table tennis score 😊
What a beautiful Design 🤩
I rarely subscribe to a channel. When I consider it, I usually watch a few videos by the person first. Not this time. Instant subscribe. Before I even finished watching the video. This is so cool!
I mostly print things I designed myself, but I'm planning to print this. Been wanting to keep track of how many containers of water I drink each day. This will be perfect!
Thank you for the kind words. Like you, I too mainly only print things I make/design myself.
This is absolutely brilliant. The design must have taken ages!
WOW! Why did the RUclips Gods take so long to show me your channel!?!? I'm printing this and subscribing. Keep these free designs and great videos coming!!!
Amazing! Now a suggestion:
Leaf springs or similar instead of rubber bands, and plastic screws or some nice snap together (with reverse open possibility).
So it is 100 percent 3D printed. =)
When I saw his 3D printed springs, I had the same thought. Especially considering that today’s thin rubber bands tend to go off reasonably quickly. More so, making the design 100% 3D printed (including snap together instead of screws), would be truely next level!
F' ING BRILLIANT !! How satisfying is that! Thank you, this is a fun project. Mine is half printed so far.
Count down and / or connecting multiple segments would take this over the top. Amazing work keep it up. +1 for subscriber count!
thanks for making this free and not trying to nickle and dime people who are just trying to have fun building stuff for free not havibng to worry and have anxiety. i really do apreciate youf or not being irrationally greedy
I really love this thing, great design! I might have an area of improvement: The „locking spring“ (inner part of the spring) doesn’t have enough force to lock number one into place (after some use). I guess it needs the most force out of all the numbers when counting form zero to one. It worked fine at first but after some use it won’t count from zero to one. I‘m probably going to squeeze some foam behind that spring to increase the force. For a design improvement: Maybe „support“ the spring by making the cam flat or even a little bit concave at the number one position. Of course stiffening the spring somehow would work too.
It could also be that I‘m missing something.
This is one of the most impressive things I've ever seen printed. The level of thought and math behind it is nuts. People don't realize, you can use CAD to do a lot of heavy lifting, but not for the creativity side of actually conceiving how to go about this and knowing what cams to use. Amazing work.
A lot of people overuse the word "engineering" when talking about prints and inventions. This is NOT one of those instances.
Thank you!
I agree, CAD is a great tool to get ideas into drawing form. As for the creativity side of things, this project has been an absolute blast. The best part of projects like this is the continuing improvements and progress. Much more to come!
That mechanism is amazing. What a great job!
Fantastic Project , I'm thinking about printing it but first modifying it so that instead of the manual button it's possible to put a stepper motor by controled with AVR Microprocessor, I could then replicate 4 displays and turn it into a beautiful wall clock !!!
Very nice project indeed!
I suggest moving the actuator to the right side (maybe with a detachable extension rod to the top to keep the existing functionality), and add a recessed "carry lever" on the right side so it can operate a digit at it's right and be stack-able.
Of course the amount of digits would be limited by the force needed to turn from 9999... to 0000...
Fascinating! You have a very pleasant and calm voice, clear instructions and the project seems "doable", it really tickles me to power up my 3d printer right away! ☺ Thanx very much, you got a new subscriber!!!
Thank you for the kind words!
This is absolutely beautiful - design/theory and execution. Awesome. A mod to allow for servo control (to make a clock) would be great.
The most wonderful thing i've seen... Thank u
This is a very cool project! Thanks for sharing - I admire the dedication to making something like this and taking the time to explain the operation.
Glad you enjoyed it!
Awesome project. For the inner parts not to be seen, you can use a constant white background as a zero, and hide the relevant segments when counting, using the same case's color.
Incredibly ingenious
Excellent! Subscribed! Thanks for sharing!
Awesome job. It is a just mechanical mesmerising mechanism to look at. I ❤ it. As a mechanical engineer who like to play with his 3D printer, I clearly now what my next print will be.
Bravo, it is good work and very intelligent.
Thanks for making this really cool design free. You are a real one for that.
I was thinking how it could be actuated electronically. Wheels turning. Awesome job!
Awesome work! I need this project evolved into a powered clock!
I really like this! Great job
Pretty amazing! You areca master Sir... well done! Awesome design and very clear video. I love how it is all 3D printed.
Downloading as we speak
Fantastic work here!
Really awesome concept, video, and delivery. I’m going to love printing this. Subscribed!
Amazing design and great build video. Thank you for sharing with us.
I have absolutely no idea what I’d use this for but I want one.
What a great job!!!
The only thing I'd change is replace the 4 dome type screws with flat heads to make the whole stack back flat.
This is one of the coolest things I’ve seen! What a cool and accessible project for 3D printing.
That's a remarkable piece of engineering!
Bless you for making this available.
Nice design! Clever cam and gear arrangement. I'll test this at my grandson's hockey games and we'll see how it hold up.
Such a nice video. Impressive design and a very good and full detailed explanation. Thank you!
This is cool as hell. 7 segment displays will always have a special place in my heart, because I had to lead and carry a group project designing a FPGA circuit for a countdown timer driving one of these. Translating that into something so physical, so mechanical, is awesome. Great design.
We need a translucent case version to see what’s going on! Brilliant!
I think you'd have to injection mold that, I'm not aware of any filament that is anywhere near clear. But yeah it would be cool if this was adapted to an off the shelf clear case.
That's pretty cool, could use something like that when I am loading my dump trailer so I don't overload it with buckets from the tractor.
I would love to see a loud clicky version of your clock with this new design, I just love the sound
I can definitely tell you’re a This Old Tony fan, awesome project!
Thank you! I actually just had to search for that channel. I had not heard of him!
The mechanism is incredibly, I definitely printing this model, you are a genius
Incredible engineering. Thank you for sharing.
This is SO. Friggin. COOL!!
Poka Yoke: If you offset the key in the shaft out of the center, each with a different amount, you'll prevent wrong assembly of the cam wheels - 6:28
Great stuff! Thank you for going into so much detail. I can't wait to make this!
Will the 2 number body stl be made available as well?
Yes it will. Should be posted this week. I need to tweak one little part of it and then I'll create a new post.
Ain't gonna lie, this is pretty cool. Subscribed.
You've earned yourself a new sub JUST based on this video! Can't wait to see what else you've done and will do!!
i think this has potential to be the most compact mechanical display.
wow, just appreciate all the work that went into it behind the scene. Only thing I would change is to remove the visible slot, although this might make the device slightly wider
If this is not genius, nothing is.
🤣🤣🤣
😂😂😂
If this 7 seg display is genius, this ruclips.net/video/Ug06dhahqg0/видео.html is out of this world. Some insane cad work from this guy
^^
@@dmontes133here is something to consider, however, the thumbnail to this video upload is a 4.
Wish my print worked like yours. :)
Thanks for sharing.
This explains so much about how this works. Great video, thanks!
Superbe ! Bravo ! Congratulations from Paris. 😊
I just want to click it! Thank you!
Imagine one where the numbers count in reverse for a countdown!
This is SO great. Beautiful design. How about adding another timing gear that can protrude sideways and power a carry in the neighbouring unit. So we can have 2 or 3 chained for larger numbers. Just brilliant bravo!
Nice design. Now it could use a carryover to combine multiple modules while retaining only one push button.
Definitely adding to my to do list. Awesome stuff. Thanks for sharing! Subbed.
Thank you!
wow dude taht's superb!
wishing u luck to a profound youtube channel
This is pretty slick. Though on something I designed that had rubber band then spring approaches someone redesigned it to use magnets (reversed poles) to work as springs which was a good idea in the compact space + for a longer lifespan.
Thanks! I would prefer to get away from rubber bands on future designs. Magnets do sound appealing. I'm going to consider them.
finally someone made on of these thank you
Nice project. You have a new subscriber. I'm looking forward to future projects.
Very nice design with a great end result!
Beautiful project, congratulations, I'd love to have a 3D Printer to try it, really good stuff, it is wonderful what it is possible to do nowadays with one of those machines, thanks for sharing!
Thank you! 3D design and printing has been a total blast!
Level 1000 version. Print in place completely assembled and with 4 digits
Very well done, I could have used these years ago for outdoor sports score keeping.
Really cool idea! I'll have to try making one one day!
Really cool, my grandson will love them.
its impressive how you get soo much, with soo few parts, and interesting combo of simple complexity.
my suggestions are....
1. silicone bands, since rubber bands degrade pretty quickly.
2. the ability to select a number, not just cycle through till you reach the one you need.
3. use M3, M4, M5, screws, not wood screws, as they are the standard for 3d printing, and lots of other things, and would be more common for people to already have, or find.
4. version with and internal button, or is otherwise hidden, instead of sticking out the top, so you can make a nice neat looking clock with it.
This print is so great! I actually ended up using some hairbands I had laying around instead of rubber bands, but mileage may vary with those hahah. Thank you for putting together the video as well, otherwise I am sure it would have been fairly confusing to put together. I did have to sand some of the cams down, but that's probably just a tolerance issue on my side honestly.
Thanks so much for posting this one! It's awesome!
Thank you for the comment and feedback! The tolerance issue is something I'm working to reduce with the ongoing design.
I had not even considered hairbands! Glad to hear those worked.
That is an amazing project, congratulations.
I hope in the future the rubber bands get replaced by compliant mechanism, rubber bands, at least those simple yellow ones used to hold money, which are the only ones I can find in my country, get ruined after a few months, specially after a hot summer, they melt and glue to the object resulting in a mess. Also the screws, 3d printing allows for so much freedom in shapes otherwise impossible to make by any other manufacturing processes, so many interesting latching options, screws almost feel like a step backwards.
I don't disagree! Phasing out the rubber bands and wood screws are high on the list of future improvements.
Super Nice design! And clear explanation. As a remark I would like to mention that having it fully printable would be a big plus (with compliant springs). Rubber bands do not last that long and need to be sourced. Any ways great project!
Thank you and I like the suggestion of fully printable. I need to explore deeper into printed spring designs that allow for longer stroke distances without experiencing plasticity.
I like how the 6’s have the tops
This is so next level for me!
You did really well there! The most I like it's the inners, because it looks like it could be driven by a motor.
And maybe you didn't think of this, but if you can stack these in sync, (and in parallel) these could be used to replace all the electronic ones seen on almost every shop, so that not electric power would be needed to run these. All the best!
A very impressive design
