What has your dog done for you lately? If you’re lucky, maybe you get something fetched once in a while. Big whup. Erik Schiegg hit on a way to make his dog useful for a change, by equipping it with a solar charging vest. The dog runs around outside all day, and Erik’s phone gets charged thanks to the solar panel on the dog’s back. While this may not be as efficient as a stationary solar panel, most of us don’t have the space or money for one of those, and this is a cheap and easy DIY solution to mobile solar charging… Think hiking and camping trips and stuff.
You can easily wire up something like this yourself; all you really need is a solar panel (which you can find at online hobby shops) and a battery pack. Or you can just buy one of these and a roll of duct tape. Your call.
