$5 Bicycle Cell Phone Charger (Wind Turbine with build in Battery)
I think I have seen it all now. I love charging my small devices with solar but that’s not always easy when you are taking a bike ride. This little beauty fixes that problem and allows you to charge your phone, GPS, go pro or what ever you need charged via an old computer fan attached to your bike.
The fan powers a battery which in turn charges your phone so you can take a 2 or 3 mile bike ride and still charge your device when you are not actually riding. This is a pretty neat DIY. Check it out and let us know what you think. Will you be making one?
