What kind of NPN Transistor would you recommend? I noticed it's part number is not listed so I can't tell what one to use.
Breadboard layout: I don't know which Transistor model it needs, so I went by basic knowledge of transistors to finish the layout. I'm very sure it will work, but knowing a model would help the layout be more clear.
I also made a Microsoft word document that contains both the circuit diagram and the breadboard layout in a neat, two page, file that is ready to print. This file is availbe online and you can download that here.
