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, 3D ...
Single-Digit v2.1 STL Files: www.printables.com/model/8600...
Two-Digit v2.1 STL files: www.printables.com/model/8692...
Files updated on 5/5/24 to use 3D printed screws; no longer requires wood screws.
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.
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 kzhead.info/sun/mclmadmMjX-Hn6c/bejne.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.
Compliant springs in place of the bands and a way to link multiple together would be fantastic upgrades. Great project, thanks for sharing! :)
WOW! Why did the KZhead Gods take so long to show me your channel!?!? I'm printing this and subscribing. Keep these free designs and great videos coming!!!
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.
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 !!
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!
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!
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.
Pretty impressive! Purely mechanical projects are so satisfying.
Thank you for sharing this and making the files available. Very well designed and explained. Great for helping my grandchildren to count!
This is one of the coolest things I’ve seen! What a cool and accessible project for 3D printing.
i am happy I landed on the good side on KZhead. 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!
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!
I think the design of this product is very beautiful, this is how products should be made. Pragmatic and reparable
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.
F' ING BRILLIANT !! How satisfying is that! Thank you, this is a fun project. Mine is half printed so far.
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!
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.
The mechanism is incredibly, I definitely printing this model, you are a genius
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!!
This explains so much about how this works. Great video, thanks!
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
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!
Count down and / or connecting multiple segments would take this over the top. Amazing work keep it up. +1 for subscriber count!
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.
That's a remarkable piece of engineering!
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.
Thanks for making this really cool design free. You are a real one for that.
Great design and instructional video. Thank you!
Amazing design and great build video. Thank you for sharing with us.
Ain't gonna lie, this is pretty cool. Subscribed.
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!
Very well done, I could have used these years ago for outdoor sports score keeping.
Incredible engineering. Thank you for sharing.
wow dude taht's superb! wishing u luck to a profound youtube channel
I was thinking how it could be actuated electronically. Wheels turning. Awesome job!
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
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.
Nice project. You have a new subscriber. I'm looking forward to future projects.
Slick design, easy sub, look forward to everything you create
Very good design. Congrats!
This deserves a 👏 and a subscription... This is absolutely top notch and great audio quality which I appreciate. Thx
Thank you!
We need a translucent case version to see what’s going on! Brilliant!
A fantastic project and expertly presented. I will be making one of these for sure to track boxing rounds. The big button will be easy to press with gloves on. Many thanks. Subbed! Cheers 👍🇦🇺😎 🥊
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...
Great Build! Subscribed. Looking forward to your future projects
Thank you. I'm excited to see where this goes.
Beautifully done!
Very nice design with a great end result!
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!
Mechanical engineering making a comeback of note.
I would love to see a loud clicky version of your clock with this new design, I just love the sound
Great design and presentation!
Awesome work! I need this project evolved into a powered clock!
Excellent! Subscribed! Thanks for sharing!
Superbe ! Bravo ! Congratulations from Paris. 😊
A very impressive design
Brilliant design
Really cool, my grandson will love them.
Definitely adding to my to do list. Awesome stuff. Thanks for sharing! Subbed.
Thank you!
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.
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!
Wow! Great design! Bravo! Keep it up 😁
Really cool idea! I'll have to try making one one day!
Awesome mechanism! Bravo, subbed
I really like this! Great job
*_Absolutely fabulous!_*
GReat project, thank you for sharing!
Fantastic creation, very clever and smooth, thanks!
Thank you too!
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.
Great design and great video explaining it!
Bravo, it is good work and very intelligent.
Fantastic! This was a great video with great detail and explanation. I've been working on my own design for a smaller 7 segment, but I'm not sure I'll get close to the same thickness with your slim profile and clever cam design.
Thank you and good luck! I like the slim design of this one but I'm also considering making a version where the cam stack can be printed as one piece which would add a bit of depth to the body. The slim design can be sensitive to sloppy tolerances.
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 !!!
finally someone made on of these thank you
This is brilliant. Now to figure out how to attach this to a chip and a motor for a clock
Coming soon. I'll be releasing a version 2 clock based on this... kzhead.info/sun/oLynisiem4KGdIE/bejne.html&ab_channel=Flower-3D
very nice. Bravo ! Next step is to handle a carry to handle next digit box
This is fantastic, thank you for sharing it! I'd love it even more if it counted up to F ;)
Wow majestic Idea man!!!!! Satisfaction to death “
i think this has potential to be the most compact mechanical display.
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.
Very nice 👍🏻 Thanks for sharing 👍🏼
Brilliant! Well done sir.
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
Brilliant design.
Nice design. Now it could use a carryover to combine multiple modules while retaining only one push button.
Great projetc, great design and the Best exlpanation
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.
Bravo! Very, very clever.
Amazing work!
Awesome work! My first thought goes to how you could make this display electrically driven (which would probably also need a zero position feedback). You could then use multiple segments for making a clock, or a multi-segment counter etc. That would be even more awesome!
Agreed! I'm finalizing a clock version of this digit based on version 1 seen here... kzhead.info/sun/oLynisiem4KGdIE/bejne.html&ab_channel=Flower-3D
Well done mate.
Level 1000 version. Print in place completely assembled and with 4 digits
That is so cool. A smaller version with ~3 digits could be very useful.
Damn dude that's awesome! Thank you!
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.
Came out great
great design !!
Very cool project.
Great Ideas !!! I love It !!! 😍
