Split Flap Display – Part 1

I recently came by this Technology Connection Video, and I am intrigued by the mechanism of a split flap mechanical clock. I then ran across this GitHub project for a split flap display and I decide to make my own.

I made one tweak to the design: I made the letters laser engraved and cut out of card stock instead of PVC cards. This includes code changes for generating double-sided SVGs, which made this a lot easier. The PR is here.

The result is actually pretty good.

There’s a bit of work left to do, but this looks great for a first attempt.
