The Most Drool-Worthy Pip-Boy to Date Can be Yours

Pip-Boy props are nothing new in the maker world, especially since the availability and prices of 3D printers have made the undertaking more straightforward. Something about bringing a piece of the Fallout universe into the real world is just incredibly appealing – so much so that Fallout 4 collector’s editions included a Pip-Boy phone case. However, because of practical limitations these props are usually just plastic shells that house a cell phone. [zapwizard] wasn’t satisfied with a purely aesthetic prop, so he has decided to design his own Pip-Boy 3000 Mk4 from scratch, while retaining as much of the functionality as possible.

For the few of you who are unfamiliar, the Pip-Boy is a wrist-mounted computer from the Fallout series of games. From a gameplay standpoint, it’s used to manage your character’s inventory, stats, quest data, and so on. Because of how often you interact with the Pip-Boy throughout the game, it has become very near and dear to the hearts of Fallout fans, which has driven it’s popularity for prop-making.

It’s no wonder, then, that we’ve featured a number of builds here on Hackaday in the past. All of these builds have been impressive, but [zapwizard] is taking it to a whole other level. As a product engineer, he certainly has the experience necessary to bring this to life, and he’s not skipping any details. He’s starting by modeling everything up in CAD, using Solid Edge. Every knob, button, dial, and latch has been reproduced in meticulous detail, and will be functional with completely custom electronics. [zipwizard] is still in the design phase, but he should be close to getting started on the actual build. He’s also considering offering a limited run of units for sale, so be sure to get in touch with him if that tickles your fancy!

Visualizing Ballet Movements with E-Traces

When we think of wearable technologies, ballet shoes aren’t the first devices that come to mind. In fact, the E-Traces pointé shoes by [Lesia Trubat] may be the first ever “connected ballet shoe.” This project captures the movement and pressure of the dancer’s feet and provides this data to a phone over Bluetooth.

The shoes are based on the Lilypad Arduino clone, which is designed for sewing into wearables. It appears that 3 force sensitive resistors are used as analog pressure sensors, measuring the force applied on the ground by the dancer’s feet. A Lilypad Accelerometer measures the acceleration of the feet.

This data is combined in an app running on an iPhone, which allows the dancer to “draw” patterns based on their dance movements. This creates a video of the motion based on the dance performed, and also collects data that can be used to analyze the dance movements after the fact.

While these shoes are focused on ballet, [Lesia] points out that the same technique could be extended to other forms of dance for both training and visualization purposes.

Is That Google In Your Pants?

Google’s Project Jacquard is tackling the age old gap between controlling your electronic device and touching yourself. They are doing this by weaving conductive thread into clothing in the form of a touch pad. In partnership with Levi Strauss & Co., Google has been designing and producing touch interfaces that are meant to be used by developers however they see fit.

touch-sensitive-jeans-thumbThe approach that Project Jacquard has taken from a hardware standpoint is on point. Rather than having an end user product in mind and design completely towards that goal, the project is focused on the interface as its product. This has the added benefit of endless varieties of textile interface possibilities. As stated in the video embedded after the break, the conductive touch interface can be designed as a visibly noticeable difference in material or seamlessly woven into a garment.

As awesome as this new interface may seem there are some things to consider:

  • Can an unintentional brush with another person “sleeve dial” your boss or mother-in-law?
  • What are the implications of Google putting sensors in your jeans?
  • At what point is haptic feedback inappropriate? and do we have to pay extra for that?

We’ve covered e-textiles before from a conductive thread and thru hole components approach to electro-mechanical implementations.

Impedance Tomography is the new X-Ray Machine

Seeing what’s going on inside a human body is pretty difficult. Unless you’re Superman and you have X-ray vision, you’ll need a large, expensive piece of medical equipment. And even then, X-rays are harmful part of the electromagnetic spectrum. Rather than using a large machine or questionable Kryptonian ionizing radiation vision, there’s another option now: electrical impedance tomography.

[Chris Harrison] and the rest of a research team at Carnegie Mellon University have come up with a way to use electrical excitation to view internal impedance cross-sections of an arm. While this doesn’t have the resolution of an X-ray or CT, there’s still a large amount of information that can be gathered from using this method. Different structures in the body, like bone, will have a different impedance than muscle or other tissues. Even flexed muscle changes its impedance from its resting state, and the team have used their sensor as proof-of-concept for hand gesture recognition.

This device is small, low power, and low-cost, and we could easily see it being the “next thing” in smart watch features. Gesture recognition at this level would open up a whole world of possibilities, especially if you don’t have to rely on any non-wearable hardware like ultrasound or LIDAR.

The Simplest Smart Glasses Concept

Google Glass kind of came and went, leaving one significant addition to the English language. Even Google itself used the term “glasshole” for people who used the product in a creepy way. We can’t decide if wearing an obviously homemade set of glasses like the ones made by [Jordan Fung] are more creepy, give you more hacker cred, or just make you look like a Borg. Maybe some combination of all of those. While the cost and complexity of developing for Google Glass was certainly a barrier for hacking on that hardware, this project is just begging for you to build your own and run with the concept.

[Jordan’s] build, called Pedosa Glass, really is pretty respectable for a self-built set up. The Arduino Nano is a bit bulky, and the three push buttons take up some room, but it doesn’t kill the ability to mount them in a glasses form-factor. An FLCoS display lets you see the output of the software which [Jordan] is still developing. Right now features include a timer and a flashlight that uses the head-mounted white LED. Not much, we admit, but enough to prove out the hardware and the whole point would be to add software you wanted.

Admittedly, it isn’t exactly like Google Glass. Although both use FLCoS displays, Pedosa Glass uses a display meant for a camera viewfinder, so you don’t really see through it. Still, there might be some practical use for a little display mounted in your field of vision. The system will improve with a better CPU that is easier to connect to the network with sensors like an accelerometer — there’s plenty of room to iterate on this project. Then again, you do have an entire second ear piece to work with if you wanted to expand the system.

Check out the video demo after the break.

Disney’s Designing a Smart Watch That Knows What You’re Touching

Did you know Disney actually has a huge R&D subsidiary? It’s called Walt Disney Imagineering, and they’ve come up with some pretty interesting technology. They’re currently working on a smart watch interface called EM-Sense that uses an electromagnetic signal to detect and learn what the user is interacting with.

Basic machine learning allows the watch to learn what different devices “feel” like on an electromagnetic scale. It’s capable of detecting things you would expect, like appliances, power tools, and even electronic devices — but it’s apparently sophisticated enough to tell when you’re touching a door handle (and which one) depending on the structure and EM feedback!

They better explain the technology in the follow video, and demonstrate a use case for it where the smart watch can lead you through activities while giving you tutorials on skills you may need. Sounds like the beginning of a real-life PipBoy!

Development Tools of the Prop-Making World

We’ve seen them before. The pixel-perfect Portal 2 replica, the Iron Man Arc Reactor, the Jedi Lightsaber. With the rise of shared knowledge via the internet, we can finally take a peek into a world hidden behind garage doors, basements, and commandeered coffee tables strewn with nuts, bolts, and other scraps. That world is prop-making. As fab equipment like 3D printers and laser cutters start to spill into the hands of more people, fellow DIY enthusiasts have developed effective workflows and corresponding software tools to lighten their loads. I figured I’d take a brief look at a few software tools that can open the possibilities for folks at home to don the respirator and goggles and start churning out props.
