yes even i got fed up seeing 7 segment display driven by individual servos. What a waste.

@@ekaggrat : A waste indeed but there should be a limit, you could use a single servo to drive the four displays as well, specially if it's an incremental counter only. Even in electronic displays, all multiplexing isn't the ideal solution but it's the cheapest. That said, your system is really clever and your job quite inspiring.

@@raphanunu6912 yes i did have a single motor but setting time gets tedious . so I have 2 motors one for hours and one for minutes. I have seen people making clocks as incremental counters with one motor. But look carefully they are not practical to use as a everyday clock.

Split flap can do letters also, and they are faster.

@@Alkatross yes but they are boring.

🤨

must have pasted over the second half... I meant "he did put it on github" :(

@@marcg2233 Thanks! Didn't realize that

yes then try adjusting time on it.. I tried to find a balance between the old and he new. old tech with modern controller to keep it on time 😂

@@ekaggrat Each unit would be driven from a different stage of the clock. Hours and min driven from different gears. I don't know how to do the math and figure it out yet but the principle should be the same as a flip clock. Match the cams and the gears together (with math) and the speed is governed by the clock mech. I'd think it would be simple for someone that knows how to do the math (I don't lol) Hum. If the display mechanism is one full rotation to go from 0 to 9 then it should be simple to drive it with a clock mechanism that's turning at 1 revolution a min and gear reduction for each additional digit 😉 Add: if the gearing and everything is correct the the clock mech is what would adjust the timekeeping not the numbers

It's not really that hard, just basic cam systems

A good 3d printer

@@platinumsky845 Sure, everything looks easy after someone else has done it, do it first and then talk

@@E_y_a_l there's not really a point of doing something like this from an engineering perspective unless it solves a problem in an efficient way, the reason why "most engineers would give up on it" isn't because it's hard, it's because there's no point to it even though it's not a challenge in the first place. When it comes to impractical designs like this, there IS value in the artistry of it, but at that point it's just a question of what design you decide to make. In these scenarios even the simplest of engineering principles goes a long way because they're being used outside of their typical use scenarios, it's still nothing special from an engineering perspective and your claim of "let's see you do it first" only applies in an artistic sense, still unrelated to the comment and my reply which were about ENGINEERING, not artistic capability. Edited because I apparently can't use proper sentence structure after 8pm today 🙃

Exactly

thanks!

sure you can start by building a single module. If you get it right contact me i will send you the rest

thanks!😀

thanks a lot

thanks. done with grasshopper3d and vray

mechanical clocks, combustion engines and fountain pens have their own charm and should not go away in front of the modern solid state devices

Change the drive speed instead

@@yelectric1893 No, it wouldn't work. What Vertu Joe wants is for the completed digit to stay still for longer. What is needeed is to reduce the arc responsible for the transition between digits so they occupy a smaller angle.

@@kalinunesferreira815 ahh. Well, I suppose. Perhaps a non linear drive speed though to complete arcs at weird rates? Different cams would be a more straightforward way.

I was thinking a pi pico and steppers, it would completely change the design though and essentially each hex segment would just have an on or off, not the constant rotation. I think its cool enough as is, even with its flaws on timing and the time the digits show.

Thanks a lot

cool thanks.

thanks!

thanks

it is a big distraction to have it on the desk.

yes i did that before but it became tedious to adjust time so i made it controlled by two stepper motors

someday maybe

It moves only once in a minute . It stops on the exact digit and stays that way till the minute elapses and then moves on. Mechanically it is hard to dwell on a single digit. That would make the cams much larger.

yes that's exactly how it works. 7 segments 7 cams

yes kind of

i don't think youtube likes links but, check the description and you can navigate to thingiverse from there

@@adog3129www.printables.com/model/672617-eptaora-clock

thanks

?

it is dead steady . just moves once a minute. so simple to see just like any digital clock

now don't start trolling them 😜

@@ekaggrat Well at least now we know that copyright stuff means nothing. I just wanted to know how those 7 disks were shaped the way they are.. now I know. The programming part isn't an issue. tell me, where are you placing the hall sensors and are there any wires involved ??

@@g.o.a.t9804 no they are wireless. the micro controller works with magic.. the steppers work with free energy..

@@ekaggrat C'mon.. enough with the jokes.. help me out a little. I don't need any codes, just the mechanism

@@g.o.a.t9804 for lazy people here is the link :www.thingiverse.com/thing:5555533

i wish i had the resources to do that. very expensive to make one in brass

??

@@ekaggrat all 👌

for now i have upload one of the modules as it is hard to put together. you can find it on my thingiverse account. feel free to change.

thanks for the idea. i will upload it to my channel soon

for now only one module on thingiverse : www.thingiverse.com/thing:5555533

never, small so you dont need 🤔

done . please check again

@@ekaggrat Thanks a lot. Already prinitng :) When can we expect the complete project to be published? :)

@@ekaggrat I am simply not able to bend the springs from the 0,2mm wire. The hooks form the 0,4mm are easy but the 3 turns springs are simply not staying in place. How did you do that?

@@kikihobbyrepair there is a variation in the music wire diameters . The one i have is around 0.27 mm . You can see in this video how i did it : kzfaq.info/get/bejne/f56FeMJz396Yd4k.html

@@ekaggrat Thank you for the video. Mine is just a random 0,2 and 0,4mm spring steel wire and they are 10 times more rigid like yours (they really want to jump back to their original position). I have printed myself a jig to make it easier though but it still suc*s...

you don't need one. The digits move every once in a minute and the carry over gears in-between 2 digits snap the second digit in place when the first one completes one circle. Mechanical counters also use a carry over mechanism .A geneva drive wont work in this case

@@ekaggrat I meant that, in the current mechanism, the lowest digit spends most of its time changing between positions, always in motion. It has a certain "kinetic art" aesthetic to it, but as a clock, it would be easier to read if the digit stayed still for a time, before quickly snapping to the next digit and then staying still again. This kind of intermittent motion is what a geneva mechanism achieves. I do not in any way imply to replace the cam-and-follower mechanism, but only to alter the speed with which it is driven.

@@Niohimself I think you understood the video wrong. In reality the digits just move one step every one minute and the stepper motor snaps it into place. Just for the video I ran the clock fast . Sorry for the misunderstanding

@@ekaggrat Ah, I apologize for jumping to conclusions then.

it is only 12 hours for now.

@@ekaggrat Sorry for the late reply. What about 11.59 to 12.00?
