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.

  Ok thats making my brain hurt. I’m clearly not a mechanical engineer!

  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!
