did someone here built his own?
Here are some teardown pics:
Apple iPad Camera Connection Kit | Tear-Down.info :
And here the pinout of the dock-connector:
Apple iPod, iPhone (2g, 3g), iPad Dock connector pinout and wiring @ pinouts.ru
I can't imagine it is too hard...maybe the supply voltage is a problem, since there is no 5V output.
Any help appreciated!
