How does this Mechanical Counter Work?

[@emma70707]

We still use these for cell counters in the lab! Very cool to see how the internals work.

[@Engineezy]

Glad you enjoyed 😀

Now let's use that concept to build a clock! 🤩

[@Rouverius]

Actually, these haven't totally disappeared. For example, you can still find them on asthma inhalers. In any case, yeah, there is so much clever stuff in those kind of total mechanical systems. Thanks for sharing it with us!

[@Engineezy]

Interesting that they are still using the mechanical version! Thanks for watching :)

It's so funny (sad?) to see a young person get so excited about this "obsolete technology" when it is so familiar to me because I grew up surrounded by it.... And they say you're old when policemen look young.... Sigh!

[@Kahraktar]

This is awesome! I feel like it was a missed opportunity to use it to count how many times you filmed the intro though. :P

[@Engineezy]

Mightve broken the counter ;)

[@floretan]

Is there a name for the mechanism where the lever makes the first wheel turn 1/10th of a turn?

[@christopherhorstmann5733]

Index gear. Also check out the Geneva gear.

[@BigerBoy]

Why so many dislikes? Cuz we have to pay for the models?

I remember these counters. I had many different ones in my childhood, but I don’t remember where they came from )). But I remember that all of them had RESET button, pressing on it all digits on all wheels set to zero. I am wondering how this was made.

[@Engineezy]

My guess is there would be a torsion (rotational) spring in it that would wind up as it counts, and when you hit reset it would unwind the numbers back to 0. (Just a guess though)

[@Bentleytalksaboutstuff]

I had one of these counters and I took it apart, and all the wheels had a set of 9 teeth (10 teeth but 1 was missing), with the missing tooth being at the 0 position, and the reset button was just a group of racks, and when the wheel made it to the 0 position, and would disengage from the rack. Hope this helps.

Really cool 👍🏻👍🏻

Thank you!!

[@pratiksawant7096]

Can we use the Geneva mechanism instead of an 8-tooth gear?

[@mayanksoni3103]

Your amazing person and your projects also amazing and unique.😍👍❤ can you tell me which software your using for making this projects for printing

[@Engineezy]

Thank you! I use Solidworks!

[@jarrenvanman2570]

Another great design. Can you do a flip style counter?

[@Engineezy]

I'm gonna put it on my list!

Thanks Sandra :)

[@maximusboscus]

Cool. Now you need to do the Enigma machine :)

[@TurtleEngineer0]

Im wondering if this is a possibilty. If I were to redesign this counter so that it only goes to 30, and every time it hits 30 it rotates another wheel, with a month, technically, wont it be a perpetual calendar?

[@Engineezy]

Definitely possible!

[@TurtleEngineer0]

@@Engineezy :D Im going to start designing! I will let you know when I finish

[@ganumba11]

Yo that was amazingly informative!! Keep up the great work!!

[@Engineezy]

Thanks! Will do!

[@Guhhhhhhhhhhhhhhhhhhhhhhhhhhhh]

Are the tolerances ok if printed at 50% or 75% size?

[@GoldenArchange]

"Its a shame the art is almost lost to us now"... locks it behind a pay wall

[@GoldenArchange]

But that's capitalism. I love the model, great work!

[@corymynhier5532]

Just curious. If the display is at 999 and you pull the thing will the whole thing go back to 000?

[@Engineezy]

Exactly! So satisfying :)

[@jadenruanes1858]

There isn’t infinite rotors.

I'ma share because old tech is still tech

[@Engineezy]

Sure is!

[@CHSidChou]

modification of geneva mechanism, nice

[@61-2learn]

What happens when you turn it backwards

[@Microwave217]

It counts down

[@ronenen]

Actually a counter, even a mechanical one, is digital by definition: It shows an actual number.

If only my printer was working 😅
