I have been thinking about purchasing a Kindle (probably a Kindle 4) to use in a photo frame project. I was hoping someone could offer advice on a good starting approach.
The project concept:
Use a library of photos as a daily image calendar. Take a photo from a directory, and overlay it with text for today's date, and a short message (eg Good morning). Change the photo every day.
My initial thought was to do this with a Raspberry Pi as a VNC server, and leave it running with a photo slideshow, but this sounds terribly inefficient.
My next idea is to use the Pi to do the image processing (scrape the web for cool photos, apply an overlay, save it as a single picture), and pass that to the Kindle. What would be the best way to display this picture? Does the Kindle support FTP in addition to SSH over USB? If so, it should be simple to set up a cron job to pass a new photo to a screensaver program every 24 hours, unless I'm missing something.
I am reasonably proficient with Python and Linux development (bash scripting, C).
