Pi scanner project: solar powered

The Raspberry Pi 2 B is up and running on solar power:

The laptop that does scanner audio process is dying and the Pi will (hopefully) take its place.   A 3A DC-DC converter steps the nominal 12vdc down to 5vdc.  The power runs into the hub on the right and I also use it for charging phones and the like.

For the curious:  this is a 45w Harbor Freight setup feeding a 12v deep cycle battery.  I’ve also got a 60w panel and a couple other controllers but they aren’t being used at the moment.
