This is A replica of the same PADDs seen in Star Trek Enterprise. I decided to build the light up version like they did in the show and so you can also read it in the dark as well.
I built this PADD from the same cabin light box's like the originals. The Graphics where done in Photoshop and is a composite of images I found of the ship and CG Layout. All the text is readable and describes some of the key fetchers of the NX-01, including its measurements, internal systems, and decks.
The raised detail on the outer bezel of the PADD came from A kit I picked up from Matt Munson whom also has A tutorial on how to built the PADD. The only thing messing now is the small numbers for the 2 rubber squares.
