I have been working on a sunrise project that is heavily inspired by Ken Murphy's amazing History of the Sky project. I loved what he did, and I decided to use a Raspberry Pi to do something similar using the Chicago Skyline and our daily sunrise. I was completely sure how to make this project work, and I still have some unanswered questions. Things are coming along nicely, though. I thought that I would post my first 30 days of sunrises here for you to see. You can also link to it here (https://youtu.be/ixQvy3rIkEU).
My colleagues at DePaul let me set up a camera. My 'weatherproof' box is really a plastic sandwich box from Target. I use a Dropbox uploader to send all of my movies to my Dropbox account every day, and I use another Raspberry Pi to download them, break them in to stills, and batch resize them. I then used Imagemagick to make a tiled 'montage' and that gets compressed into another movie.
I hope you enjoy it! I have instructions on this process that will follow soon!
