Another was a program which drove an optical digitizer
I built from a
fiber-optic cable, an infrared fiber optic detector (variable
potentiomiter) and some tape. It plugged into the joystick port and used
the Vpot analog to digital converter the machine uses to 'read'
paddle-type game controllers. The tape-wrapped end of the fiber optic
cable fit nicely into one of the pen bays on an Atari 1020 color plotter.
Run a photo into the plotter and start the program. After a few minutes,
the photo is on screen in 16 shades of grey. Saving the image was as
simple as an incremeted "peek" and store of each location in screen
memory. I was very proud of it at the age of 14. I still have the program
and some 'girly' pictures I digitized with it, but the scanner hardware is
long lost. Sigh. My adolescent friends TOTALLY understood. ;-),
I saw a similar construction on Computerclub (German television), but they
built a drum scanner instead, wrapping the source image onto a roll which sat
upon an old grammophone, while the scanner head was slowly moved downwards. No
girlie pictures, though. =)
