I have a science fair project coming up for my school (I'm in 10th grade) and I had the idea to make a wind turbine that I can use to charge a phone/ipod/other device. What I'm wondering is, what will I need to do this? Not exact materials, but what components?
I know I'll need the turbine itself. I've looked online and found many plans and example of how to make these.
I was looking around a other DIY wind turbines (larger scale) and they all had something called a charge controller. I have no clue what this is exactly, but I assume it regulates the power output or something along those lines. Most of the ones were 12v controllers, but I would think that would be way too much for a phone. So what is a charge controller, and what size/outage will I need to charge a phone?
Also, would I be able to use a system like this to charge an ipod? I assume I could just cut one of the USB chargers and hook up the raw wires to the system. Would this work?
While looking around online, I found a wind turbine phone charger for sale called Oragne (link below). This is pretty much exactly what I'm looking to make, but just a DIY one. And not nearly as professional.
