Hi, I found interesting project: Parallel port SD card reader for linux. User connect SD card to parallel port and mount it in linux as normal USB flash disk.
I have another idea - is possible to use Arduino with SD card connected over RS-232 to PC and mount this SD card as USB flash disk? 1) Insert SD card to Arduino 2) Connect Arduino over RS-232 (or FTDI USB) to pc 3) On PC mount it as USB flash disk
Is there any such project?
Hardware is easy. But Arduino sketch and PC driver will be problem.
I know this is completely unnecessary and a waste of time. But it's a fun challenge!
