Are those LEGO-compatible axles?
- Yes! 🤓
Awesomeness. Please show us a video of the end result!!
- Here you go!
  
  This is wicked cool! Great work
Insanely cool, thanks for sharing! Gives me some fun ideas...
Just yesterday youtube showed me this video and I thought to myself what a waste it is to use 30 servos for a project like this:

Your solution is so much cooler.
- This video was the inspiration for my project!
- Yep. I thought of this video as well!
  
  This is a much better engineering solution. Only requires 4 motors.
  
  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.
- Here is an alternative Piped link(s):

  Piped is a privacy-respecting open-source alternative frontend to YouTube.
  
  I'm open-source; check me out at GitHub.
Genious idea! Now all you have to do is print the segments in a transparent plastic, black the complete front, and backlight the module.
Dang, camshaft + Geneva is really obvious in hindsight, cool.
This project is now on Printables!
