This weeks thing was built for a friend for the Iron Man inspired dress she has made for Iron Fest.  The ARC reactor is made using 11 superbright 3mm LEDs connected to a pair of AAs.  It is then sewn onto a scrap of denim from an old pair of jeans for a bit of structure and covered in white fabric from an old t-shirt.  The dress was made by Miss Jones herself, including the repulsor glove, the latter using an EL panel left over from one of her Tron routines.  I don’t have a pic of the reactor completed but it works best as part of the outfit after all;

The actual structure of the reactor is really simple, I set out the LEDs in the required pattern using blutak then bent the pins so when soldered together the pins themselves form the structure.  This makes for a far lower profile and easier to integrate into the outfit.
