I just quickly glanced over the Instructable, but since it uses a monitor, I assume it has VGA input. If so, you just need a Mini-DVI to VGA adapter, which Apple conveniently sells.

wonderful, will i be able to see on both screens or will one black out
I just checked Mac Help--it said that the default setting was two identical images, but depending on the computer, you could also set it up as an extended desktop or a single external display.
I'm not sure...I've never tried it, I just know that you can get them. I think that you can switch between a duplicate screen, external monitor only, and a continuous desktop that connects between the two.
