Re: A real situation

I have a friend in Yemen who\'s in the limited situation that the R-Pi for developing countries are targetting. Due to political turmoil, he is limited to only two hours of electricity everyday. Even if R-Pi can run (I think I read it only needs 2 W) on your regular batteries, there are no display available.

Low-{cost,power} displays, anyone?

I think your friend would be better off buying a netbook and connecting it to a car battery.

At 121 British pounds, doesn\'t really fall into the cheap category.

But I guess he has a TV? So the composite output of the Raspberry Pi can be used.
Using a 12V to 220V adapter he can use some car batteries.

A portable travel TV?
I have a ROADSTAR LCD-2500/S PORTABLE TRAVEL TV 2.5\" LCD AV IN. Connected my Playstation2 via composite. Screen is ok, mono sound. Built-in battery charger (4xAAA). You could connect it to car battery. Paid 28,80€.

If he can wait, then perhaps see what happens with the CSI connector that may allow the right kind of LCD module to be connected without expensive drivers, thus keeping costs low and power required to a minimum.

Alternatively, if composite input is ok, try getting a low cost Reversing Screen, which would run directly from 12V car battery (price & power requirements verses size applies of course):
