If only I had time on my hands, and didn’t have to resort to blogging in the five minutes between lectures, I would totally try to duplicate this project. This guy, Anthony Le, built an (almost) working Iron Man Suit. Actually, he built a War Machine suit, because War Machine has more cool toys.
It cost US$4,000, is held together by “high impact urethane” and more than 1,500 rivets. The helmet was formed from clay and finished with resin. The spinning cylindrical gun is controlled by a button in the suit’s glove, and can fire paintballs. The motorised helmet opens and closes. Here it is in action (I think, I haven’t watched this yet).
