lost opportunity - closed hardware

miriam_eI bought a cute little keychain photo display device the other day. It is tiny -- similar to a box of matches, but not as thick. It can store and show about 50 color photos on its little 128x128 pixel display. I was interested in hacking it to use as an extremely low power display for a small computer that I might carry in my pocket. Sadly, its architecture is utterly closed. It connects via USB, but looks to the computer like a CD drive. The computer is assumed to be a Microsoft Windows XP machine which automatically downloads and runs a program that lets the user move pictures to the device. It doesn't present the storage area to the connecting computer at all. Any movement of data must be done via this proprietary, secret interface.
Sad. A lost opportunity. By assuming people are idiots they truncate the possibilities of their device. Most people these days don't have any problem moving stuff in and out of their flash drives without specialised software.
I might still be able to bypass its processor, but I doubt it. I expect the display electronics will be integrated in the one chip, and I don't know enough about driving such a display to build my own yet. If I was going to do that I'd start from a simpler beginning, with a standalone display, adding memory and a simple processor. But I have too many other things to do so I guess this one falls into the couldabeen area. [sigh]
