okay a few questions again..
Would it be hard to make a usb keyboard work on the tab (like cutting up the usb cable and replacing it with a 30pin dock connector?)?
And how much effort would it take to create a hdmi out? or a normal video out if possible..? Because I actually need an old video out port but on the samsung site is says that the video out represented is not compatible with the 10.1..
and where do you solder everything on? I've yet to find a picture of the 30pin connector which tells you where to solder..
Where would I solder in this image? http://shop.kineteka.com/images/thumbs/0000564.jpeg
Or should I just get a tab-out like this:

From a portable battery, like one of those from Zagg, that supply 1A.
