Mandatory shout-out to Gibson's Pattern Recognition, where the main character Cayce Pollard gets involved with a miserable failing recluse intelligence agent who is obsessed with these mechanical calculators & the Curta specifically.

Thankfully there is a writeup available, for jogging of memories or hearing about it, https://www.google.com/amp/s/blue-ant.tumblr.com/post/315663...

I count the passing of time by how many times this makes it to HN front page. I think this is the 5th time I’ve seen it here

There's also http://curtamania.com/curta/code/home.html, a site which has appeared on HN a few times but not for its Curta material.

Wake me up when there is a 3d-printable version.

And a fun video of Adam Savage playing with Marcus Wu's 3D-printed Curta: https://www.youtube.com/watch?v=j9uRckJLqLk

I know two people IRL that have both made (or at least started) a 3d printed version.

You have to make it super size because the precision needed is crazy.

This is one of my favourite objects ever.

I have a certain admiration for really well crafted mechanical objects.

Does anyone know of a compilation of such gear? I'd love to discover new stuff of this level of care and mechanical knowledge.

There's gotta be a special place in hell for people that try to force a Holocaust survivor out of the company they founded that manufactured a product they invented.. It never ceases to astound me how despicable people can be

you’re mistaken. greed is the highest virtue

Can't tell if this is irony lol
