Let's Make Robots!

documentation

Any good mechanical engineering books?

I just finished reading this: http://www.allaboutcircuits.com/. It really helped me understand all the electronic background of robotics. Now I feel like reading about mechanical engineering so does anyone have a good book or website to recommend? 

Parallax Incremental Rotary Encoder

I've found an awesome rotary encoder (I believe it was the smallest on Rootshop) but I have no idea how to use it? I believe there's an input, a ground and a signal pin, but I don't know how to configure it or anything. I'm going to be using it with an arduino.

I've digged the web and have found no documentation. Just sayin

Thanks ;)This thing is approximatively a 2,5 cm cube
