So Good news, I've been able to make the neck section and the Backpack, so I've got most of the big piece's sorted, Just the breastplate to make then It's onto the little items, I've also got my hands on a Warble generator (it makes the sound the eye makes) and an LED Eye scanner, hopefully I'll have a finished helmet soon.
My big problem with the costume so far is finding a Voice changer that
A) Makes the right sound/tone
B) Dosen't need an iPhone or iPod Touch to work it, and
C) Dosen't coast me an Arm and a Leg
Fingers crossed I Can find one
