Iron Man, In IRON!

February 9, 2017 by Jenny List 28 Comments

Sometimes a project comes our way which has so much information contained in it as to be overwhelming, and on which it is difficult to know where to start. A good example is [Barry Armstead]’s Iron Man suit, to which we were introduced through a very long forum thread that spans several years.

Home-made armour is a staple of the cosplay world, with many astoundingly good creations being produced by fans. What makes [Barry]’s Iron Man suit stand out from the crowd is its construction; instead of fiberglass or vacuum-formed plastic he’s used real metal. (It’s steel. But steel contains iron, right? We’re calling poetic license.)

The best place to follow progress on the suit is probably [Barry]’s YouTube feed, in which he has so far racked up 44 build logs. We see joint articulation tests, early test walks, the iconic helmet taking shape, and the repulsor simulated with a nano sprayer. With so many videos to watch, you’ll be there quite a while. The one we’ll leave you with below the break is fairly straightforward, the first look at the entire exoskeleton in bare metal.

Hacklet 41 – Prosthetics Projects

April 3, 2015 by Adam Fabio 8 Comments

Throughout human history, mankind has worked to enable those with disabilities. This applies especially to those who have missing limbs, either from injury or since birth. Every time technology improves, prosthetics improve along with the way. Unfortunately this now means prosthetics have become expensive systems. Hackers, makers, and engineers are working to make prosthetics more affordable, and more available to everyone. This week’s Hacklet focuses on some of the best prosthetics projects on Hackaday.io!

We start with [Open Bionics] and Affordable Bionic Hands For Amputees. The [Open Bionics] team are using 3D printers to bring the cost of a prosthetic arm and hand down from up to $100,000 USD to just $1000 USD. They’ve also reduced the time to create a custom device from weeks to just 5 days. The team’s current hand has five degrees of freedom, uses electromyography (EMG) for control, and weighs just 268 grams. [Open Bionics] discovered that many amputees are willing to trade off functions for a lighter weight device. Having a sensor and motor studded hand won’t help much if the wearer is worn out after just a couple of hours!

Next up is [yash.gajra56] and RE-ARM. RE-ARM is a prosthetic arm project which aims to help both those who have lost limbs, and those with full or partial paralysis of a limb. Movement is provided by radio control style servos. Control is via voice commands and Bluetooth from a cell phone. [Yash] has incorporated feedback into RE-ARM by using flex sensors. Processing is handled by an Arduino. We like the low-cost, low tech approach RE-ARM uses. We’d love to see everyone have access to a 3D printer, but unfortunately the world isn’t there quite yet. RE-ARM uses readily available components to build a functional prosthetic. Nice work [yash]!

[OpenBionics] brings us Affordable Prosthetic Hands. No, you didn’t read that name wrong. There are two “Open Bionics” on Hackaday.io! This [OpenBionics] team has no space, and is based in Athens, Greece. The other [Open Bionics] team does have a space between the words, and is based in Bristol in the United Kingdom. We’re hoping the two groups can come together and collaborate now that they’re both using Hackaday.io. This [OpenBionics] team is working on prosthetic hands, in the sub $200 USD price range. The team has come up with a novel thumb design which provides nearly full functionality with only one rotating joint. [OpenBionics] also allows their users to selectively lock digits, which allows for up to 144 different grasping postures.

Finally we have [Daniel Mead] with Third World Medical Equipment (Arm). [Daniel] created this project as an independent study back in high school. The idea is create a simple arm with a gripper out of cheap or freely available items. The gripper is fashioned from a bicycle brake. The fitting system is especially novel. [Daniel] used an old soda bottle to create a custom mold for the amputee’s residual limb. Plastic bottles are generally made of polyethylene terephthalate, or PET, a thermoplastic. [Daniel] placed a wet sock over his arm, and a plastic bottle over the sock. Holding the plastic bottle above a fire created enough heat to shrink the bottle to his arm. the sock provided room for padding, and insulated him from getting burned during the molding process.

That’s about all the time we have for this week’s Hacklet. As always, see you next week. Same hack time, same hack channel, bringing you the best of Hackaday.io!

Hacklet 20 – Halloween Hacks

October 24, 2014 by Adam Fabio 6 Comments

Hey, did you know that Hackaday.io is continuously being updated and improved? One of the coolest features this week is the new LaTeX based equation editor. That’s right, you can now put symbols, equations, and all sorts of other LaTeX goodies into your posts. Check out [Brian Benchoff’s] LaTeX demo project for more information.

Every holiday is a season for hacks, but Halloween has to be one of the best. From costumes to decorations, there are just tons of opportunities for great projects. We know that with an entire week left before the big day, most of you are still working on your projects. However a few early bird hackers already have Halloween themed projects up on Hackaday.io. We’re featuring them here – on the Hacklet!

[philmajestic] is in the Halloween spirit with his AVR Halloween Pumpkin. [Phil] created a motion activated Jack-o’-lantern with an ATmega328 as its brain. The AVR monitors a PIR motion sensor. When motion is detected, it flashes Jack’s LED eyes and plays spooky sound files from a WTV-020-16sd audio player. This is a great example of how a bit of work can create something cooler and infinitely more flexible than a store-bought decoration. Nice work [Phil]!

The littleBits crew have been working overtime on Halloween hacks this year. We definitely like their Halloween Creepy Portrait. A motion trigger, a servo, and a few glue bits are all it take to turn a regular portrait into a creepy one. When the motion detector is triggered, the servo moves a paper behind the portrait’s eyes. The replacement eyes look like some sort of demon or cat. Definitely enough to give us nightmares!

[jeromekelty] helped his friend [Greg] build an incredible Animatronic Iron Man MKIII suit. The suit features RFID tags which trigger suit features. Since we’re talking about an Iron Man suit, “features” are things like shoulder rockets, boot thrusters, and a helmet that lifts up to reveal “Tony Stark”. No less than four Arduinos handle the various I/O’s. The suit even features an Adafruit WaveShield for authentic sounds! The electronics are just one piece of the puzzle here. [Greg] is a card-carrying member of the Replica Prop Forum. His MKIII suit is incredibly detailed. We especially like the weathering and battle damage!

Finally, [Griff’s] son is going to be wearing a Crochet Cthulhu Mask, with Arduino controlled tentacles for Halloween this year. [Griff] is an experienced crochet hobbiest. He’s mixing his love of needlework with his love of electronics to build the animated Cthulhu mask for his 4-year-old son. The mask is based on a free crochet pattern from ravelry, though [Griff] is making quite a few changes to support his application. The mask will be smaller to fit a 4-year-old, and will contain servos to move the tentacles. We haven’t heard from [Griff] in a while, so if you see him, tell him to post an update on the mask!

If you haven’t started working on your Halloween hacks, get busy! But don’t forget to upload them to Hackaday.io! If we get enough, we’ll run a second Hacklet with even more great projects. Until then, you can check out our Halloween Projects List!

That’s about it for this frightful episode The Hacklet. As always, see you next week. Same hack time, same hack channel, bringing you the best of Hackaday.io!

3D Printing Goes Hand In Hand With Iron Man Inspired Prosthetic

October 17, 2014 by Sarah Petkus 10 Comments

It’s exciting how much 3D printing has enabled us to produce pretty much any shape for any purpose on the fly. Among the most thoughtful uses for the technology that we’ve seen are the many functioning and often beautiful prosthetics that not only succeed in restoring the use of a limb, but also deliver an air of style and self-expression to the wearer. The immediate nature of the technology allows for models to be designed and produced rapidly at a low-cost, which works excellently for growing children. [Pat Starace’s] Iron Man inspired 3D printed hand and forearm are a perfect example of such personality and expert engineering… with an added dash of hacker flair.

With over twenty years of experience in animatronics behind him, [Starace] expertly concealed all of the mechanical ligaments within the design of his arm, producing a streamline limb with all the nuance of lifelike gesture. It was important that the piece not only work, but give the wearer that appropriate super hero-like feeling while wearing it. He achieves this with all the bells and whistles hidden within the negative space of the forearm, which give the wearer an armory of tricks up their sleeve. Concealed in the plating, [Starace] uses an Arduino and accelerometer to animate different sets of LEDs as triggered by the hand’s position coupled with specific voice commands. Depending on what angle the wrist is bent at, the fingers will either curl into a fist and reveal hidden ‘lasers’ on the back of the hand, or spread open around a pulsing circle of light on the palm when thrust outward.

The project took [Starace] quite a bit of time to print all the individual parts; around two days worth of time. This however is still considered quick in comparison to the custom outfitting and production of traditional prosthetics… not to mention, the traditional stuff wouldn’t have LEDs. This piece has a noble cause, and is an exciting example of how 3D printing is adding a level of heroism to everyday life.

Thank you Julius for pointing out this awesome project to us!

Homemade Superhero: [James’] DIY Exoskeleton

August 30, 2014 by Marsh 44 Comments

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.

Sci-Fi Contest Roundup: I Am Iron Man

April 25, 2014 by Brian Benchoff 5 Comments

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.

Motorized Helmet

[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.

Anamatronic

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.

Create Your Own J.A.R.V.I.S. Using Jasper

April 9, 2014 by Nick Conn 79 Comments

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.
