Inspired by the first and second Iron Man movies, and having seen decent results with my previous two costumes, I began the daunting task of building the Mark III suit.
I began planning in May 2010, and decided to make the suit as fully functional as the real thing.
The suit includes a motorized faceplate, toggle eye lights, cooling fan, speakers, microphone and voice modifier - all contained within the helmet.
The torso will include a glowing arc reactor which can increase in brightness, dual shoulder missile launchers powered by CO2 canisters, cooling fans, and will house the microcontroller and battery system for the suit.
The left arm contains a motorized shield which can fan open upon command, but I may switch it to gyroscopic activation instead.
The right arm contains a rocket housing which is also powered by CO2, and will fire a Nerf missile/dart upon voice command.
The hands contain repulsors which are each composed of five 10 000 mcd white ultrabright LEDs, a 2" hobby speaker and PVC housing. The brightness and pitch are controlled at the wrist by a linear potentiometer.
The boots are constructed to allow me to step in, hands-free, with the leverage from my heel causing the boot to snap shut with the help of neodymium magnets.
The voice command is run by the VRBot Module, and prompts a pre-programmed voice (Jarvis) to respond to what I say. Jarvis will also monitor the battery life and notify me when the power is getting low.
Finally, when all of this is finished, I intend to add extra servos many sections of the armour to enable a "control surfaces check" as per the first movie.
As a final note, much of the internal structure of the suit is composed of technic Lego pieces. I initially intended for only the mechanical parts to use Lego, but found that the range of pieces, durability, editability, breathability and low cost were good reasons to use it for the majority of the framework.
