Super-ambitious project by Jonatan Nielavitzky: a 3D printed Babbage Difference Engine! He says it's a work-in-progress but it looks pretty polished to me.

Show him some appreciation on youtube if you have a moment! (I'm trying to encourage him to keep going)

Just saw this old machine with tons of oddities: BOTH 10-key and “full” keyboards, 3-pronged digit shifting crank, 2 big asymmetrical carrying handles. Gotta look at all the pictures.

Tons of low hanging jokes I sidestepped in favor of the comment-bait thumbnail, which seems to be going well on TikTok.
