Did you get a nice shiny new Paperwhite Kindle to replace your old one? (I haven’t yet. I’m waiting until the inevitable moment when I drop my Kindle Touch and break the screen; I’m currently on my third.) If you did, you might be interested to learn that when you’re not using it to read books or jailbreaking it so you can change the wallpaper, you can use your Paperwhite as a wireless, ultra low-power display for your Raspberry Pi.
We featured the original Kindleberry Pi hack from Ponnuki back in September. That hack required cables, and only worked on the old Kindle 3 (the version with the keyboard), not any later versions – plus, it looked a bit odd because to keep the screen in landscape mode you had to turn the whole assembly on its side, so the keyboard was rotated by 90 degrees. The new Kindle 5 (the Paperwhite) has no keyboard, a faster refresh rate, and a backlight that can be turned on in dark conditions. So Max Ogden has polished Ponnuki’s original Kindleberry Pi idea, and produced a really tidy piece of kit: a Raspberry Pi with a Paperwhite display, a wireless keyboard and a tiny wireless router. He says:
The advantages of the Kindleberry are pretty desirable for me:
Week-long battery life: the Pi and the Kindle both have low power ARM processors so you can use any USB charger to power them
The Kindle screen is designed for use in direct sunlight
The whole setup is small enough to carry around in a pouch inside my normal backpack along with my normal laptop. I work from coffee shops in Oakland and often move around by bicycle during the day — now I can work from almost anywhere and still be at least a little productive….
