Solar Power Hour
It took several tries, but we can finally call our internet "in a box".
Everything is secure and functional, and should be water-resistant (I just have to clean up the cables once I'm done fiddling with it.) The left compartment holds the battery. You'll notice it's massive compared to the actual microcomputer, the small black box on the right. This is so it can operate for several days indoors or in the rain. The bottom compartment has the voltage regulator attached to it, which takes the direct output of the solar panel and ensures that nothing gets fried by a sudden flash of sun.
We'd like to credit Laura Hosman with SolarSPELL at Arizona State University for the idea!
