A few weeks ago i say a youtube video short of a guy making a clock using arduino and gears.. and i thought i want to make one too.. So i remix his original design and make one of my own design using tinkercad.. the clock timing will be controlled by an arduino nano and stepper motor.. the whole clock will be powered by a 5v usb cable.. but mine will be different by making the whole clock needle looks like it floats using magnets..
Im going to also put a window on the base of the clock so you can see the gears turns when its operational..
If you like the project.. please consider donating to us so we can make more awesome project like this in the future
have you seen this one https://www.instructables.com/Hollow-Clock-4/ Different gears, same magnets.
wow.. that is really compact set of gears.. i dont think i can design something that complex.. but the magnets positioning is the same method..
