Yep. I thought of this video as well!

Just yesterday you’ve showed me this video and I thought to myself what a waste of is to use 30 servos for a project like this:

You’re solution is so much cooler.

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 motor even further. I think I can get it down to two, maybe even one.

Wow, never occurred to me before, but this is such an elegant, and simple solution.

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.

This video was the inspiration for my project!
