The arc reactor in Iron Man 3 has a different design without wires. We used white acrylic and a blue dry-erase marker in the etchings to achieve the above effect.
Dab some E6000 adhesive on the back of the coils, and gently glue the circuit assembly to it. Don't press so hard that the metal wire comes in contact with the pixel ring PCB-- the glue acts as an insulator. E6000 dries clear and flexible in about 24 hours.
If you're in a rush you can use hot melt glue. It's inferior to E6000 in almost every way, but it will get the job done fast.This guide was first published on Oct 02, 2013. It was last updated on Sep 21, 2018. This page (Affix Faceplate) was last updated on Sep 11, 2017.
