I'm making sort of a desk cycle. What are the ways to make silent circular motion with resistance ? (I don't need to adjust resistance and resistance should be just light.)
If I didn't need resistance, I could use a bearing. Or maybe there are regular bearings that have some specific resistance ? I see there are also magnetic bearings but I had really difficulties to find their prices and those ones that I found costs in hundreds. Are there some cheap ones, ideally ~ 15 or less bucks ? Or do you have an idea how to achieve silent circular motion with resistance ? I was thinking of something like winding/unwinding - continual never ending loop against some weight but that would require changing of the motion from wind to unwind to make it never ending and honestly it seems it isn't very simple to design.
