- ***NEW VERSION v3.0 see video here: • 7 Segment Counter v3.0...
Version 2 of the 7-Segment mechanical counter. Improved design. This particular model is a sequential counter (numbers 0 - 9) that receives a linear input to cycle the display.
Previous Version 1: • 7 Segment Display v1.0...
Single-Digit v2.1 STL Files: www.printables...
Two-Digit v2.1 STL files: www.printables...
Files updated on 5/5/24 to use 3D printed screws; no longer requires wood screws.
New Version v3.0 video here: ua-cam.com/video/LMwjKzrQjHg/v-deo.html
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 ua-cam.com/video/fe-9uTVMQlo/v-deo.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.
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.
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
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 !!!!
Compliant springs in place of the bands and a way to link multiple together would be fantastic upgrades. Great project, thanks for sharing! :)
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.
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.
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.
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!
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
Pretty impressive! Purely mechanical projects are so satisfying.
i am happy I landed on the good side on UA-cam. 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!
This is absolutely brilliant. The design must have taken ages!
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.
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.😊
I am not sure why anyone would want something like this, but it is very interesting.
Table tennis score 😊
WOW! Why did the UA-cam Gods take so long to show me your channel!?!? I'm printing this and subscribing. Keep these free designs and great videos coming!!!
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!
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!
Im printing 2 of the 2 segment versions for a competition im holding. THANK YOU!
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.
Count down and / or connecting multiple segments would take this over the top. Amazing work keep it up. +1 for subscriber count!
This is absolutely beautiful - design/theory and execution. Awesome. A mod to allow for servo control (to make a clock) would be great.
F' ING BRILLIANT !! How satisfying is that! Thank you, this is a fun project. Mine is half printed so far.
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
That mechanism is amazing. What a great job!
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!
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...
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!
I have absolutely no idea what I’d use this for but I want one.
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 !!!
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
Really awesome concept, video, and delivery. I’m going to love printing this. Subscribed!
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.
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.
Such a nice video. Impressive design and a very good and full detailed explanation. Thank you!
Incredibly ingenious
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!
Fantastic work here!
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.
Amazing design and great build video. Thank you for sharing with us.
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.
Thanks for making this really cool design free. You are a real one for that.
The mechanism is incredibly, I definitely printing this model, you are a genius
That's a remarkable piece of engineering!
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.
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!
Excellent! Subscribed! Thanks for sharing!
Bless you for making this available.
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
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!
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.
wow dude taht's superb!
wishing u luck to a profound youtube channel
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
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!!
Ain't gonna lie, this is pretty cool. Subscribed.
Bravo, it is good work and very intelligent.
Incredible engineering. Thank you for sharing.
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!
Awesome work! I need this project evolved into a powered clock!
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.
I like how the 6’s have the tops
Very nice design with a great end result!
If this is not genius, nothing is.
🤣🤣🤣
😂😂😂
If this 7 seg display is genius, this ua-cam.com/video/Ug06dhahqg0/v-deo.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.
Superbe ! Bravo ! Congratulations from Paris. 😊
I really like this! Great job
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
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.
Wish my print worked like yours. :)
Thanks for sharing.
Nice project. You have a new subscriber. I'm looking forward to future projects.
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.
Fantastic build and looks like a works an absolute treat! Have to say I am getting some serious This Old Tony vibes from your content production :D
Thank you! I had to search for This old Tony. I had not heard of that channel.
Nice design. Now it could use a carryover to combine multiple modules while retaining only one push button.
Once again a video makes me wish i had a person that could 3D print things for me. Of course i would pay the material costs and some for their time.
Its a shame you dont sell these.
I've been debating on offering a fully assembled unit for sale. V3 will likely be the version that I intend to sell.
You could add files for the rubber bands as well to be printed in TPU. If you also make the shell snap together, you won't need any extra hardware! 100% 3D printed! Or design 3D printed screws, that also works fine.
This explains so much about how this works. Great video, thanks!
Definitely adding to my to do list. Awesome stuff. Thanks for sharing! Subbed.
Thank you!
Level 1000 version. Print in place completely assembled and with 4 digits
At first this looked pretty cool. Decided to build the dual one as a present to someone who teaches children with special needs - thought it could be used as a teaching a. After a week of tinkering I have come to an understanding that the biggest flaw of this design is the thickness of the followers and cams and too tight clearances between different cams. After several days and evenings of sanding and filing the parts the followers keep getting stuck or not actuating (slipping past the correct cam). If the cams and followers were thicker with bigger gaps between them, the assembly could have been more repeatable for everyone using different printers. I'm using Prusa Mk3s+ and found out that turning on the ironing for the cams and followers helped to make them really flat and with acceptable tolerantces. But still... I can't give this unusable counter away as a present unless I wan't spend the next year finetuning it.
This deserves a 👏 and a subscription... This is absolutely top notch and great audio quality which I appreciate. Thx
Thank you!
Totally outstanding content. And this is a very impressive design. Thank you for all the effort you put into this video. It was well done.
Thank you very much!
I just want to click it! Thank you!
Imagine one where the numbers count in reverse for a countdown!
See v3.0, it offers countdown capabilities!
Slick design, easy sub, look forward to everything you create
Very well done, I could have used these years ago for outdoor sports score keeping.
I like the design, really cool. 3D prints often require a level of fettling to get things working, but after two build attempts with different filament, I'll wait for V3.
The mechanism would bind up and fail after a couple of cycles.
There is nothing retaining the seg plate in place, maybe a retaining ring between the seg plate and the mid plate?
The cam locating pegs on the Segment plate need to be longer so the cams stay in place, I had to ream the cam pin recesses and the gear barrels to fit the locating pegs.
The gears need to be thicker to stop them jumping. I understand their purpose from your reply to @ouroborusseven 2 weeks ago, but when this happens the strain of the gears appears too great and they jump, causing the cams out of synchronization, this in conjunction with he push action pegs jumping out of the spring barrel slots causes the mechanism to fail completely.
The push action pegs fitting into the spring barrels need to be longer to stop them jumping out, maybe a t-slot mechanism?
The push action is too flimsy. I can't see how to do that without increasing the mechanism thickness...
Rubber bans, Yeah Nah...
I don't mean to be critical, but every design can me improved.
That's what testers are for...
I also had a really frustrating experience building this. Wasted a lot of time, but it turned up to be an unreliable design.
Thank you for the feedback! I completely agree that every design can be improved, including this one. Most of what you commented is currently being addressed/improved in the upcoming v3. One of the biggest challenges I'm facing based on feedback is creating a final design that is compatible with the inconsistencies between various printers. I really want this to be a "plug and play" experience for everyone.
I'm slowly moving away from rubber bands. V3 currently calls for the push-action to engage (2) 4mm x 50mm springs. The segments still require a rubber band but the seg-plate now has additional pegs to better support and distribute the rubber band's force on the segments. Segments and followers will be one printed piece requiring no supports (no more glue!). Many elements have had their depths increased for better engagement with acting components (to eliminate the jumping over effect).
Thank you for testing this design.
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.
A very impressive design
Amazing! I guess you would need some kind of pivoting mechanism instead of the current sliding mechanism to get rid of / hide the tracks for the segments... Otherwise I would recommend printing it in black to hide the tracks, which add visual noise to the numbers. If possible, chamfering the outlines of the cutouts would also help reduce the shadow cast on unused/empty segments. Incredible design, execution and video!
Really cool idea! I'll have to try making one one day!
Very nice, a slight improvement would be to add 4 small posts for the first band to hook over, a rectangular format slightly inside the returned position. This would reduce the force on the top and bottom pieces as it would be more of a deflection than a stretch. But it's a wonderful model
Thank you for the comment and feedback. Your suggestion makes total sense and has inspired me to begin experimenting with additional rubber band supports. I'm already seeing a few benefits.
finally someone made on of these thank you
Really cool, my grandson will love them.
This is so next level for me!
