Epicycle Clock
- berbec 3y agoI would find this much less confusing if the minute of every hour was "north"/"up"
- slang800 3y agoThis is cool. Makes me want to see if a mechanical version of this could be done.
- jareklupinski 3y agoi prototyped this using two windshield motors (powerful worm gears for cheap) and two slip rings to transfer power / position data between the arms it looks awesome but I need to work on making it easier to produce by figuring out a better way to sense where the connecting arm is (hall effect?), and do more work to account for backlash in the relatively inexpensive / tolerant worm drives i built one that rotates about the hour hand and another the rotates about the minute hand to try both ways out; it's pretty cool to see the whole thing swing around once an hour but probably not something you want in a home...
- gumby 3y agoVery nice!
- TrianguloY 3y agoIt would be nice if the "epicycle clock" words at the bottom would link to an explanation on Wikipedia or something (or display a popup). Also, with the dark mode extension the white background is black, but all the black numbers/line are still black (not white) which makes it only show the minutes and seconds hands. And it looks quite confusing. Still nice though
- ifyalciner 3y agoThis is looks quite aesthetic. Also a super analogy to show new programmers how complexity increases if you introduce unnecessary dependencies.
