Interesting CD changer contraption. I am all for automating boring processes!
“The software for this gadget is relatively simple. I wrote a simple command line driven program that sequences the machine through picking a CD from the tray and dropping it in the middle, and piking up a CD from the stack on the left, and dropping it in the tray. The software also has some manual controls, which I use for debugging and aligning the machine. It does do direct I/O to the printer port. under Linux, this is easy to do if the program runs as root. Under Windows NT/2000/XP, this is much more difficult. But the machine that this is hooked up to runs Linux anyway, so no issue there.”
