My motor has finally arrived! It is a 120V 2500rpm DC motor wind turbine generator, and it was only $22 on Amazon. It is actually much smaller than I originally imagined, measuring about 4.5 inches long. I have attached a picture of the motor below.

The reviews I read online for this motor are all positive, and one user said he can get up to 10V by just spinning the shaft with his hand! With blades attached, it should easily get over 12V in the wind, and much more on a strong windy day.
I am going to head to McGuckins this weekend to pick up the PVC pipe for the blades. I am getting some help from an online resource, which suggests getting 2′ long 4″ diameter PVC pipes and cutting them diagonally with a hand saw. Below is an example of how I will cut out the blades. The larger diameter of the PVC will allow the turbine blades to turn with ease in less wind.
I also need to create a hub for the blades to connect to the shaft of the motor. For this, I will be using a saw blade (cheap form of circular metal) to attach the blades to. I will also need a spindle adaptor and a saw blade arbor adaptor to transmit the rotation from the blades to the shaft. Once I have assembled these mechanical components, I will troubleshoot how to store the electricity that is produced.
