Pitches with Prototypes: Solar Tracker
To get the most efficient use of solar electric energy, you must keep your solar panel pointed at the sun. Manually moving the solar panel is impractical. An automated solution may be beyond the reach of many green energy enthusiasts or anyone who just wants to keep the lights on without developing robotics expertise. Hoping to fill that need is technology savvy Jay Doscher, with his prototype solar tracking robot. His tripod mounted, GPS steered solution is portable and could be used for emergencies, camping or any time off-grid power is needed.
Tool Review: SunVolt Portable Power Station
The SunVolt Portable Power Station is a portable solar panel that can be used to charge cell phones and tablets. There are actually two models, the SynVolt and the SunVolt Max.

Toolsday Hangout on Air, Live and Online Today at 2pm PST/5pm EST
Today is Toolsday here at MAKE, so you know what that means – a live Google+ hangout where we will be discussing our favorite tools and workspace essentials. The main topic of the hangout will be power, in various forms. We’ll discuss a few of the many possible ways to power your projects, whether it’s with a homemade bench-top supply, a solar panel hanging out of your window, or a kit like the Mintyboost.
How-To: Solar-Powered Raspberry Pi FTP Server
This build uses a custom 3D-printed / hand assembled case from RPi hacker Cottonpickers, which comes attached to the back of a 300mA solar panel, and has a bunch of nice features already built-in. Once you’ve got your Pi running on sunlight, David Hayward over at CNET UK will show you how to configure the Pi so you can access an external hard drive attached to one of its USB ports via FTP.
