Kind of retro style with modern tech appeals us much. For gadget freaks, technologies & materials etc would be the most exciting moment. Piano background music is a nice starter, too! Perfectly fit for the image.
This is fantastic! I can imagine how cool it would look if you could print the segments thinner like a lithopane so that an led strip inside would backlight the segments. Then when off the outer wheels would have no pattern on them, but when turned on the segments would light up and spin!
Nice idea, actually some LEDs inside will pass through the body if it is printed with transparent material. To show clear texts, internal structure should be changed slightly, but possible I think to do it with light sealing at gaps.
What about building it using a DC motor and a circular encoder (like what they use in inkjet printers). It can rotate much faster then, but I don't know what is the speed limit of the rotation for this clock's cylinders.
Exactly, the limit of the rotation speed comes from the cheap geared stepper motor that takes 4 seconds per rotation. DC motor or larger stepper motor would make the clock much faster. I selected that motor because of the price and ubiquity.
Haha, yes, it's motion is tooo complex and takes around 3 minutes if leftmost digit is changed.. so it is not for serious use but has lot of fun to see. Fortunately 90% is changing just rightmost digit and it takes around 10 seconds.
Yes, I mentioned that at www.thingiverse.com/thing:4939540 and wrote ".. the main difference is the segment arrangement. My design has 9 positions for each wheel, and segments are shared each other. Therefore It can show relatively larger digit compared to the radius of the wheel."

Cool! Just I'd rather hear the sound of its turning and clicks instead of that background music.
that's actually a 12 segment display. :) nice work

creative method, impressive!
Thanks!
Great way of doing something simple more complex just because you can! How long time does it take to change the leftmost hour? (on an average)

@@shiura maybe you could have the hours and minutes separated (eg two motors) it would be more accurate. Still a very cool complication!
I made a similar mechanism, I was inspired by the "tilted twister" design, did you see that prior to this?

god damn that's a slow clock
