We’re not just a bunch of monkeys with typewriters here at Hackaday; we don our hacker hat whenever our schedules allow. Or, in the case of Hackaday’s own [James Hobson]—aka [The Hacksmith]—he dons this slick exoskeleton prototype instead,turning himself into a superhero. Inspired by the exoskeleton from the film Elysium, this project puts [James] one step closer to the greater goal of creating an Iron Man-style suit.
For now, though, the exoskeleton is impressive enough on its own. The build is a combination of custom-cut perforated steel tubing and pneumatic cylinders, attached to a back braces of sorts. In the demonstration video, [James] stares down 170 pounds of cinder block affixed to a barbell, and although he’s no lightweight, you can tell immediately from his reaction how much assistance the exoskeleton provides as [James] curls the makeshift weights over and over. And that’s only at half pressure. [James] thinks he could break the 300 pound mark of lifting if he didn’t break his legs first.
There’s plenty of behind-the-scenes footage of the build process to be had, so make sure you stick around after the jump for a sizable helping of videos, and check out [The Hacksmith’s] website for more of his projects.

Back when Iron Man 2 and The Avengers were out in theaters, the Hackaday tip line couldn’t go a week without an arc reactor build being submitted. In keeping with the Internet’s fascination with blinkey glowey things, we expected a huge influx of arc reactors for our Sci-Fi contest. We were pleasantly surprised: all the submissions from the Marvel universe are top-notch, and the two Iron Man entries we have are simply amazing.
[James Bruton] is working on a replica of the Iron Man movie helmet, complete with a motorized face plate, light up eyes, and an OLED display for a reasonable facsimile of the horribly unrealistic on-screen heads-up display.
While a few bits and bobs of the mechanics were 3D printed, [James] is making the majority of the helmet just as how the on-screen version was made. The helmet was first carved out of sheet foam, then molded and cast into very strong rigid fiberglass. [James] put up a great tutorial series on how he did this and other parts of his Iron Man costume.
The other Iron Man costume from [jeromekelty] and [Greg Hatter] doesn’t stop at just the helmet. They’re doing everything: shoulder-mounted rocket pods, hip pods, forearm missiles, back flaps, and boots with a satisfying electronic kerthunk sounding with every step.
Inside the custom molded suit are at least four Arduinos, four XBees, an Adafruit WaveShield, and at least 20 servos for all of the Iron Man suit components. The mechanics are actuated via RFID with a tag in a glove; when the wearer waves their hand over some part of the suit, one of the mechanical features are activated.
It’s impressive to say the least, and one of the best documented projects we’ve seen in the Sci-Fi contest.
There’s still time to put together your own Sci-Fi project for the contest. Grab your soldering iron and fiberglass resin, because there’s some seriously great prizes up for grabs.
Tony Stark’s J.A.R.V.I.S. needs no introduction. With [Shubhro’s] and [Charlie’s] recent release of Jasper, an always on voice-controlled development platform for the Raspberry Pi, you too can start making your own J.A.R.V.I.S..
Both [Shubhro] and [Charlie] are undergraduate students at Princeton University, and decided to make their voice-controlled project open-source (code is available on GitHub). Jasper is build on inexpensive off-the-shelf hardware, making it very simple to get started. All you really need is an internet connected Raspberry Pi with a microphone and speaker. Simply install Jasper, and get started using the built in functionality that allows you to interface with Spotify, Facebook, Gmail, knock knock jokes, and more. Be sure to check out the demo video after break!
With the easy to use developer API, you can integrate Jasper into any of your existing Raspberry Pi projects with little effort. We could see Jasper integrated with wireless microphones and speakers to enable advanced voice control from anywhere in your home. What a great project! Thanks to both [Shubhro] and [Charlie] for making this open-source.

[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.

Following in the footsteps of [Tony Stark] this Arc Reactor replica was hand crafted using almost no power tools. From what we can tell in his build gallery, a cordless drill was his only departure from using pure elbow grease.
[DJ Maller] started his build by cutting out a disc of acrylic for the base plate. While we might have reached for a hole saw, he grabbed a framing square and laid out a center point and square cuts on the stock. Kudos for his use of an awl (we often take the Luddite approach of hammer and nail) to make an impression for his compass point to rest in. After using a coping saw to rough out the shape he sands the round up to the line with the drill and a sanding wheel.
After drilling holes and inserting LEDs he begins to build up the replica piece by piece. What looks like a recessed handle for a sliding closet doors makes up the center. The spring-like copper coils was produced by wrapping wire around a pen then stretching to the desired shape. He added a bicycle spoke wrench wrapped with copper for some additional visual appeal before finishing the decoration off with some storm door clips.
Giant fresnel lens is dangerous fun
Here’s an interesting, and rather dangerous, use for those old big screen TVs that are frequently listed for FREE on Craigslist. With the lens from the old TV built into an adjustable wooden frame, [Grant] was able to melt a stack of pennies, instantly burn wood, melt spots in concrete, and serve his family a cooked egg… Cool.
Projection mapping app helps create hologram like performance stage
[Aimino] used an iPad, a mobile projector, and a mosquito screen to create a trippy hologram like stage. It might not seem like much at first, but it’s actually a pretty interesting effect. Watching the video makes me wonder what other applications this could have in the near future.
The world’s strongest magnet
At a cost of over $14 million dollars and weighing in at 35 tons, the 45 Tesla Hybrid is the strongest DC magnet on Earth. It’s powerful enough that the film crew couldn’t even safely get in to take footage of it. Over half of their camera tapes were wiped clean just while being in the same facility that houses it!
Virtual Body chair uses 4 of our 5 senses
Created in the hopes of providing a VR experience for seniors with mobility problems who can no longer travel the world, Tokyo Metropolitan University’s Ikei Laboratory presents the ‘Virtual Body’ exhibition. Included are a 3D monitor, a pair of headphones, a fan to create breezes and spread scents, a chair that moves and vibrates, and moving foot pedals.
Iron Man laser gauntlet pops balloons with ease
If you’re an Iron Man fan with disposable income, you might want to check out this functional full metal laser gauntlet. Built from scratch using no blueprints or guides, [AnselmoFanZero] sells them for around $3K USD.
Check out how the light hits this piece of artwork. It’s a very convincing piece of stained glass… except it’s fake. [Sdtacoma] figured out a way to mimic stained glass using a single pane. The inspiration for the project came after seeing a real stained glass panel featuring Iron Man which was available on Etsy for $4500.
Due to popular demand [Sdtacoma] posted an album of the technique he used. Starting with some art found online he made it black and white, blew it up to size (this thing’s about five feet tall) and used posterizer to print it out using multiple sheets of paper.
The frame and pane were found at a recycled building goods store. After cleaning it up he used the paper template to lay out the dividing lines between different colored sections using Liquid Lead. The product had dimension to it (kind of like puffy paint for fabrics) which looks like the lead tracks between panes of stained glass. Once dry the color was added using an eye dropper to apply glass paint.
