Adding USB Connectivity to your U/W Housing
It took only a couple liveaboard trips to convince me that there had to be an easier solution to downloading photos from the camera. Opening the housing after each dive, and either swapping out the memory card, or plugging in a USB cable to the side of the camera, was not only an inconvenience, but exposed the housing to an increased chance that a small hair or other contaminant might land on the main o-ring, leading to a flood. With the long battery life of the majority of dSLR cameras, the size of the memory card becomes the limiting factor, and with RAW files on some cameras breaking 15mb, one can only shoot so many pictures before the card fills up. Determined, I set about trying to find a way to transfer files over USB through the housing. This article describes the author’s design (Matt Segal), which makes USB downloading of photos THROUGH the housing a reality.
