I’ve been reading an awesome textbook on power-loom engineering, and it’s inspired me to try to build my own all-mechanical, jacquard-style punch card reader. I have a small 3-bit version more-or-less working, and up on thingiverse in case anyone wants to build their own. I doubt it will ever happen, but it would be cool to build a super-simplified all-mechanical computer that actually used punch cards. Maybe I could call it “Plan 2.8″ instead? Anyway, eat your heart out steampunk fans!
