Title: Easy DIY 80 Column IBM Punch Card Reader
Post by: digitaltrails on Jul 26, 2012, 12:31 pm
I've just written up how to build a DIY IBM 80 Column Punch Card Reader by using an Arduino to control a CHDK firmware equipped camera.

The Arduino is just used to do the image capture, the images are then processed on a PC using some python code, this makes for a fairly easy project on the hardware side of things.

That is a great project, I really enjoyed reading about it. Amazing to see someone who still has some punch cards :)

Nice childhood memories.

I guess that makes me feel old, since I started programming in high school on an IBM 1130 with cards.   :)

Oh, me too. I was a kid then (like everybody at age 14).
Actually, I started by punching the cards (on a Juki machine). Programming with those cards came a bit later.
