Power cable? check.
What resolution is that projector again? I certainly hope it can do more than 800 x 600. My days of building traditional web applications for the masses are over and neither my slides nor my application would look as intended a small screen. I guess I had almost everything covered. Such is life. Silly oversight; life and learn.
All the same, this is going to be a fun presentation among friends and peers. Can’t wait.
