Sunrise Machine with the Tessel 2
Some time ago, I began to have a hankering to be able to automatically photograph or film the sunrise wherever I may happen to be. I liked the idea of a little machine that could determine when the sun would rise in my location and take some time lapse images of it. Thus was born the idea of a Sunrise Machine.
The Sunrise Machine can, based on your latitude and longitude, automatically record the sunrise at your location using a basic USB webcam. It captures still images over time and creates time-lapse movies from them in MPEG-4 and animated-GIF formats. If you choose, it can also tweet those resulting GIFs on your behalf. You can configure it to record different day-sun events—sunset, solar noon, the start of the golden hour, even nautical twilight. You don't have to tweet the results, if that's not your thing, and you can always create a manual time-lapse video at any time by pressing a button. All still images and videos are stored for you on a USB thumb drive.
I built an enclosure for my Sunrise Machine out of an old book. However, you can put yours in whatever you like, or not bother with an enclosure at all.
