While not a solar powered gadget in itself, the Solar Pocket Factory is a small, automated machine that produces microsolar panels that can be used in a variety of applications, such as charging cell phones, arduinos and battery packs.
The Kickstarter campaign was launched by inventors Shawn Frayne and Alex Hornstein in August of 2012, with an initial goal of raising $50,000 to ramp up the production of the device and improve the quality (and lower the price) of microsolar panels. The project ended up being fully funded, to the tune of $77,000.
The inventors have since applied for startup funding from Y Combinator (which wasn't approved), but the latest word is that their prototype machine is finished and ready for production sometime in the spring of this year. Stay in the loop with what the Solar Pocket Factory is up to at their website.
