Hi everyone,
I'm thinking about making punched cards.
http://www.ibm-1401.info/CardStockSpecifications.html you can still buy punched cards

Sure.. I'm thinking about making
custom printed punch cards for small profit.
Still missing are round corners and the right resp. nicely suited paper.
what about fan-fold paper tape?
I made a
"machine" that is able to fanfold paper tape. Yes, but.... currently only
something like a
proof of concept. It worked too unprecisely by far. It needs to be reconstructed using
precision
components instead of a mixture of pneumatics, a stepper motor, and handcrafted wooden
parts :-)
Kind regards,
Philipp
