Building an Inverted Pendulum System The Ups and Downs of Defying Gravity…

I won the bid for the encoders on ebay.  Including shipping, the total cost for two encoders is about $35.  Much better than any of the other options I was looking at.  I just hope they work as good as I expect.  Now that I have spent some money on it, I guess I am committed to building this contraption.
