This is my homemade Arduino/CHDK/Python/Linux based IBM 80 Column Punch Card Reader.  The cards are imaged by the camera under control of the Arduino and CHDK. The sdcard is transferred to Linux and the images are processed into text by a python script.  More info/designs/software at codeincluded.blogspot.com
