I'm double posting this here and in the Developer's Corner because I don't know in which this would belong, sorry. Admins, feel free to close whichever thread seems less appropiate.
Does anyone know what's the specifications for making a reading light like the ones that the "official" covers come with (
http://www.amazon.com/Kindle-Lighted...p/B003DZ165W)? They seem to power through the same socket that the serial link is connected through, and there's some kind of.. hook? on the upper socket, whch I have no clue what it is for (ground, maybe?)
How does one get voltage out of that? what's the tension? I'm guessing it's just enough current to light a single small white LED.
