I have seen Ben showing a small demo of his Rasberry Pi laptop but if you charge it and then disconect it can it be used? And if it can, then how much time will it work without a battery
There wasn't a battery on that thing. Looking back now, I don't know why not!
We still plan to make the Pi Portable, eventually.
Can you tell me how to use a 12V lcd screen for my rasberry Pi?
