I am trying to add functionality to camcorders that store data to SD cards. I would like to be able to put a connector or board into the SD slot of my camera so it looks like a regular SD card, but it is actually a shield or otherwise directly connected to the Arduino. My goal is to be able to use the Arduino to ship the video files to other locations on my network automatically without the latency involved with wifi cards like the Eye Fi. The writes would only come from the camera so I do not want to try to have two devices connected as read/write at the same time.
My question is, has anyone encountered something like this or can give me a hind as to how I might get started on something like this? My first instinct is to find some old ribbon cable from a hard drive, cut it down to the number of wires I need, get an old sd card, remove the memory and solder the ribbon wires to the contacts there. Then solder the other end into a standard sd shield. Is it that simple or is there more to it?
All that said, I am a total noob to arduino and hardware in general so any guidance from the community is appreciated.
