NVIDIA Jetson Powers Real-Time Iron Man HUD

If you could recreate any of the capabilities of Tony Stark’s Iron Man suit in real life, it would probably be the ability to fly, the super strength, or maybe even the palm-mounted lasers that can cut through whatever obstacle is in your path. But let’s be real, all that stuff is way too hard to try and pull off. Plus you’ll probably just end up accidentally killing yourself in the backyard.

But judging by the videos he’s been posting, [Kris Kersey] is doing one hell of a job creating a functional heads-up display (HUD) similar to the one Tony uses in the films. He’s even building it into a 3D printed Iron Man helmet, with the NVIDIA Jetson board that’s powering the show inside a chest-mounted “Arc Reactor”. He goes into a bit more detail about the project and his goals in an interview recently published on NVIDIA’s own blog. Continue reading “NVIDIA Jetson Powers Real-Time Iron Man HUD”

A Simple Servo Hack For An Iron Man Helmet

[James] makes some seriously awesome Iron Man props. In one of his latest helmet builds, he came across a handy hack to lock the faceplate servo in place.

You see, as awesome as it is walking around like Iron Man all day, you’re going to want to keep your faceplate up for extended periods of time. Simply holding the servo in place electronically is a waste of power, and results in the annoying sound of a servo under strain. On the other hand, cutting power to it will keep it in place momentarily — but it will also start to close under the force of gravity.

The solution is actually quite simple, by reprogramming the Picaxe-08M microcontroller, the board now shorts the motor terminals to hold it in place. This is called magnetic motor braking, and it works by creating a closed loop that makes it much harder to induce a current under load. We once added this feature to a motorized push-scooter — it’d stop on a dime, although you wouldn’t…

Stick around after the break to see an extremely in depth video on how he setup the entire system.
