5th December 2010: Arc update 2 Found out I could keep the arc reactor in place with just a small bit of fishing wire, so it was almost invisible. Since the battery was in the back of the unit there were no wires coming out that I had to hide.
Ran for over 5 hours on a simple 3V coin battery and didn't look like it was going to run out any time soon, result. I shall make the final cosmetic updates and then it will be finally complete. May consider moving on to making the arm section of the suit.
