Dude at NASA makes a Tricorder with an iPhone

NASA scientist Jing Li (and others) has created a tricorder, ala Star Trek, using an iPhone and a few little gadget bits that is able to 'sense' gases in the air. My advice: get this tricorder things to the point where it can repair broken bones and inject medicine into a human's neck, then move onto the teleporter.
