Solar powered on/off line timelapse photography
From wikiluntti
Introduction
Create offline timelapse photographer power by solar power using Raspberry Pi. When the Raspi connects to the internet, it will start transferring the images to a net storage. The uploaded photos will be then shown on a separate web page. Also, by triggering GPIO pins, Raspberry Pi will send a separate photo directly to the net storage. These photos are used to adjust the position and alignment of the camera.
