I'm testing a geneva drive (you can see it in the front in the photo), that should allow me to reduce the number of motors even further. I think I can get it down to two, maybe even one.
Oh that gearbox on the left?? I was just thinking that you could setup some gears similar to a analog clock to use only one motor. Does the geneva drive support snapping into position? With analog you'd want smooth motion, but here you'd want stepped positions. The snap is what makes this build so satisfying to me.
There is no snapping, but the geneva drive will stay locked in position when it is not moving. The thing that I haven't figured out is how to get the 3 to go back to 0 after 23:59, it needs to skip the numbers 4 to 9.
Just make it turn back by 3 clicks. If you’re watching the clock closely enough to notice at midnight you should go to bed anyway 🤷♂️
Seriously though, awesome project!
