hi all,
as you probably already know, a nice eInk display feature is that they don't need any power to display any kind of image: the power is only needed during page transitions.
Therefore it is possible to let the Nook display any given image when it is powered off without any effect on battery life.
Unfortunately, this (pretty useless, i admit; it is just "for fun"
) feature is not present on original Nook firmware, so i decided to implement it with a small modification of firmware.
More details and download on
this page of my blog.
