How to Solar Power a Raspberry Pi
Another nice bit about the Raspberry Pi is they use little juice, so makes builds like this possible. http://blog.makezine.com/2012/12/11/how-to-solar-powered-raspberry-pi-ftp-server/?utm_source=feedburner&utm_medium=feed&utm_campaign=Feed%3A+makezineonline+%28MAKE%29
