This sounds interesting. Could you shed some light in what hacking a kindle entails? Could I hook up my micro controller to the kindle and use the kindles display? Could I add gpio ports to the kindle and use it as a micro controller?

Check out using the Kindle as a raspberry pi display:

Thanks for the links, this looks very cool!

Here’s a link to a video I made: https://www.youtube.com/watch?v=Oel08SDFyIY

Of course, you can skip the server section and make the IP address point to your local server. Some caveats are you need to use pngcrush to turn the image into a format that the kindle can use.

Sure. The kindle runs linux and has a large e-ink display and battery integrated for a good price. You can do many things that you cannot do on a micro controller. For low level stuff you can hook up an esp8266 through wifi.

Please share more. I have two Kindle 3 laying around and I'd love to do something useful with them.

Everything I read about hacking older Kindles involved rooting them and displaying a HTML with whatever you wanted. That sounds too easy, and I'd like to go deeper.
