“We’re online and ready.” With those words, J.A.R.V.I.S. is about to become your next best friend. If you build him first, that is.

With Iron Man 3 making its release on May 3, it’s time for the fanboy in you to get his gear-on. Advancer Technologies has put together a step-by-step guide for crafting your own Iron Man Repulsor, complete with a J.A.R.V.I.S. greeting when you power it on. It’s muscle controlled, so when you bring your fingers into the palm of your hand, the LED lights on the repulsor will light up and you’ll hear a charging sound. The sensors track your forearm muscle movement, so when you relax your muscle, you’ll release the “charge,” and LED lights on the palm of your glove will light up. You can even quick fire by flexing and relaxing your forearm muscle repeatedly.

You are going to need some advanced materials, but once it’s done, you’ll have something to show-off while in line for the movie next month, then all you have to do is save it to have the coolest Halloween costume around.
