Phantom Terrains

The man who can hear Wi-Fi wherever he walks - New Scientist

I am walking through my north London neighbourhood on an unseasonably warm day in late autumn. I can hear birds tweeting in the trees, traffic prowling the back roads, children playing in gardens and Wi-Fi leaching from their homes. Against the familiar sounds of suburban life, it is somehow incongruous and appropriate at the same time. As I approach Turnpike Lane tube station and descend to the underground platform, I catch the now familiar gurgle of the public Wi-Fi hub, as well as the staff network beside it. On board the train, these sounds fade into silence as we burrow into the tunnels leading to central London. I have been able to hear these fields since last week. This wasn’t the result of a sudden mutation or years of transcendental meditation, but an upgrade to my hearing aids. With a grant from Nesta, the UK innovation charity, sound artist Daniel Jones and I built Phantom Terrains, an experimental tool for making Wi-Fi fields audible.

GOD DAMNIT! This is exactly the HMD idea I've been toying with for years. I've been shopping for endoscopes and pocket projectors to put together a prototype...guess I should move faster on these things

How Magic Leap Is Secretly Creating a New Alternate Reality

Don't you hate it when someone claims to have a magical new technology, but won't tell you how it works? When I saw that a super stealthy startup called Magic Leap had raised $542 million to make animals appear out of thin air, I resolved to find out exactly what was going on. Here's what I found.

Space 3D Printer Is Installed

by General Fabb

A few short weeks ago a SpaceX cargo craft carried a unique experiment: A 3D printer designed for space. Now it’s being installed.

The device was installed in the microgravity “glovebox” and will be used to study the extrusion process in a weightless environment. The first items to be printed, as is the case on the ground, will be calibration “coupons” to ensure the device is operational and properly forming objects. 

Once proven to work, the printer will produce a variety of test objects designed to check out various properties of micro-gravity-3D printed objects have predictable strength, flex and other engineering characteristics. These will be compared to control prints made on the ground to understand the differences between printing environments. 

The 3D printer was produced by startup Made In Space. This is their first 3D printer in orbit, and if it succeeds, it won’t be the last. 

No, they’re not yet printing usable objects. This is only a test to understand whether the technology works. If it does, one can easily imagine NASA equipping future spacecraft with 3D printers to enable part production onsite in space, thus avoiding the costs and delays of shipping parts by cargo craft to the space station. NASA could even transmit an entirely new design to the ISS for immediate production, a new capability for spacecraft.

THE BRAIN DUMP by Bruce Sterling

Of you Internet world people, many know our new bad troubles here in Ukraine. Beloved cool techno-culture center “Izolyatsia” is seized by ethnic rebels in city of Donetsk. Armed separatists get real drunk, bust up the art gallery, carry off all our favorite 3DPrinters. No nice gadgets left in Izolyatsia now, just landmines.

We are independent digital culture center from Frunze, Hirske, Borivske (careful not mentioning exact village where we live). In our “Brain Dump” hackerspace we are underground alternative freeware hack scene. Total do-it-yourself. Share everything, build own desks from old packing crates. Way into Linux, Wikipedia and Instructables. Every day we learn something good from Internet community.

In Brain Dump we have broadband, so we are watching cool videos from “motherboard.vice.com.” We see on Motherboard that Iraqis, Mexicans and Syrians getting shot up and bombed even worse than us. We are grateful to explain ourselves on much-respected Vice classy website backed by Intel….

New Electrically Conductive 3D Printer Filament Option

by General Fabb
F-Electric print.jpg

A new project promises to deliver “ultra conductive” 3D printer filament. 

The project is driven by Functionalize, who have launched a crowdfunding campaign to gauge interest and gain funding for further development. Their fundraising goal: USD$100,000, which could be difficult to achieve given the USD$50-70 cost to get your hands on some of this interesting filament. 

It’s called “Functionalize F-Electric ultra-conductive 3D Printing Filament”, and it can be used in most personal 3D printers using plastic extrusion techniques. 

Project founder Michael Toutonghi of Seattle was helping his son with a science project and realized they required conductive filament - but found there were no options. After throwing together a home nanotech lab (above), Toutonghi was able to create a filament formulation that achieves some remarkable characteristics.

The F-Electric filament exhibits resistivity under 1 Ohm per cm, which is at least 1,000X less resistant than currently available conductive filaments. This means you can actually 3D print circuits capable of performing useful electronic functions, such as powering an LED light. 

If this filament proves practical - not only for conductivity, but also for actual use in real 3D printers - it could open up a new world of 3D printed designs. Imagine a machine equipped with two extruders, one of which is loaded with F-Electric. You could then print objects including electrical circuits. Motors need only be dropped into position, as printed wiring would be embedded in the plastic structure, for example. 

This could require some new software tools to efficiently design objects that include basic circuitry. 

For now, you can order samples of F-Electric from their Kickstarter page in varying quantities. They expect to deliver product in March of next year.

Backcountry Drones Made With 3D Printing

by General Fabb

A new personal drone concept by Backcountry Drones makes heavy use of 3D printing. 

The drone market is exploding and Backcountry Drones has been exploring the idea of producing a rugged, easily transportable drone for back country use. Such a device could see over hills and locate landmarks not visible from the ground. But most drones are pretty fragile and would risk damage if hauled through a long hike. 

Backcountry Drones developed a unique concept for their drone involving a cylindrical design with spring-loaded propellor blades. It’s an amazing design that looks very much like a water bottle, which implies it’s easily carried by hikers. Check out the video below to see how the spring-loaded props eliminate the need for landing gear. 

Of course, the product used 3D printing technology to iterate the design of the case. Multiple parts compose the drone, providing not only support for the engine and electronics, but also a robust case capable of surviving in the wild. We can easily imagine such a machine crashing into trees, falling significant distances or pushing the edge of the landing envelope.

The project is still in development, but they hope to launch a crowdfunding campaign soon, where they hope to raise funds to transform the prototype made by 3D printing into a manufacturable product.

Scientists propose existence and interaction of parallel worlds: Many Interacting Worlds theory challenges foundations of quantum science -- ScienceDaily:

"The team proposes that parallel universes really exist, and that they interact. That is, rather than evolving independently, nearby worlds influence one another by a subtle force of repulsion. They show that such an interaction could explain everything that is bizarre about quantum mechanics."

Google’s New Street View Image Recognition Algorithm Can Beat Most CAPTCHAs | TechCrunch

Here is an interesting conundrum for Google: it has created an algorithm that’s significantly better at reading street numbers in Street View images, which helps it give you more accurate directions. At the same time, though, it turns out that this algorithm is so good, it can decipher 99 percent of CAPTCHAs (those squiggly text puzzles you often have to solve to prove you are human).

Rapid manufacturing: Iteration and Industry

by bowman
Oh yes, we did.

“Oh yes, we did.”

For the past year we have been busy building, testing, documenting and refining the process of taking 3D printed parts and using “Lost PLA” burnout to cast for parts for more robust applications. The documentation is bordering 100+pages, with 20+ pages of brute force data. We will try to keep it simple, show off with a few shiny throwbacks, hopefully inspire ideas for the potential, and give some technical specs to boost the capabilities of those open source open hardware folks who love a good clean walkthrough. [click here for more information]

Casting Data

Parts can have clean interior corners, where CNC machines would fail to accomplish because of the cutter size. Self intersecting geometry is also not a problem. Edge case castings have been hearty with 13 fins space 1.6mm apart extending 15mm up and continuous for 40mm. This means complex geometry for cooling fins has little cost to prototype.The hard part is conceptualizing how volumetric shrinkage occurs. Basically the part will shrink ~2-3% depending on the alloy, but holes will get bigger as metal contracts from the side walls of the plaster. This means that parts need to be scale up ~2% while holes need to shrink by 2%. This allows parts to be well toleranced if machined afterwards.

Extremely complex parts that cannot be machined can easily be cast in production volumes allowing standard 3D print/cast parts to; withstand high temperature applications, parts have higher strength to weight ratio, parts can be custom bearing/bushing systems(when bronze is used), and parts can be used to create custom heat sinks (when aluminum is used).

The goal was to see if multiples could be cast simultaneously to minimize cost

Katrina Van Tassel: An Endangered Species?

by Jess

If you saw this picture and your first thought was that you were looking at a costumed Princess Aurora from Sleeping Beauty, you wouldn’t be alone.

Jess as Katrina

Last Friday, Jess and I attended Disneyland’s Halloween party. It was the maiden voyage for Jess’s newest costume, in progress since spring: Katrina Van Tassel from “The Legend of Sleepy Hollow.” “Sleepy Hollow” was the second of two featurettes released together in what was the last of Disney’s “package” films. The Adventures of Ichabod and Mr. Toad was Disney Studios’ 11th animated feature, and it premiered on October 5th, 1949.

Jess was sure no one would recognize the costume, and while I thought she was mostly correct, I still believed that someone at Disneyland would recognize it. From the beginning, no one did. Most believed, as we suspected, that she was dressed as Princess Aurora. A few were confused, thinking she was a fusion of Little Bo Peep from Toy Story and Sleeping Beauty. She was also mistaken for Cinderella, and Charlotte from The Princess and the Frog.

Again, none of this was a surprise.

Katrina has probably been one of the more obscure Disney characters from the beginning. Like a Disney princess, Katrina has a wardrobe change during her cartoon. When Katrina first appears she wears a bell-shaped pink dress with a blue laced front, she carries a green parasol, and she wears a white Dutch cap. Later, at a Halloween party thrown by her father, she wears a longer pink dress with a more open neckline and no blue accent. This is the version that Jess chose to portray.

katrina02-1200

What was a surprise, was that after revealing that the costume was in fact that of Katrina Van Tassel from the animated feature, there was, to a person, not a glimmer of recognition. Not even amongst the park’s Cast Members.

“You know, ‘Legend of Sleepy Hollow’? The Halloween cartoon with Ichabod and the Headless Horseman? Narrated by Bing Crosby?”

Blank spot here – then, “You mean that ‘Sleepy Hollow’ TV show?”

“No, the Disney cartoon.”

What inevitably followed was the look of someone who you had just spoken to in ancient Babylonian. Apparently no one under the age of thirty or maybe even forty has ever seen this cartoon.

At the end of the night, on the way out of the park, someone finally recognized the costume. A girl dressed as Princess Aurora, of all things, traveling with a group of other costumed princesses, yelled “Katrina! Katrina!” from across the street, then ran over for a picture. Aurora seemed surprised she was the only person who got it – so I won the bet: someone, one person, had known who Katrina was. Fifteen minutes later one guy in the World of Disney store recognized the character as well. So, two out of many thousands. Which greatly saddened and distressed me.

As a kid, I learned to tell time largely because I wanted to be sure my family made it home from Sunday dinner by six-thirty. Sunday dinner for us was always at the same place: Furr’s Cafeteria in Arvada, Colorado. This, for us, was extremely fancy. The first thing you noticed after your eyes adjusted to the dark was the weird brick walls. As we stood in the tray line with other hungry families I studied the walls made of weird, goopy, sloppy bricks. They all looked a little melted, some much more than others. If one took the proper cues from the bricks and the medieval prints on the walls, I guess they were trying to make the place look like it was from ancient Europe. So waiting in the tray line was like traveling backwards through time to a cafeteria in the Middle Ages. A time when people weren’t so good at making bricks but they could still make Jell-O in every color conceivable.

We each got a tray and pushed it down the line while we picked which plates we wanted from the hundreds that were cooling on crushed ice beyond the glass sneeze guard which was at an adult’s chest level. As a kid I could easily reach beneath the glass and get whatever I wanted. I always chose the same things: Salisbury steak which came with a mandatory side of green beans, green Jell-O presented in cubes, and a sugary green drink. Dad always got the chicken fried steak.

As I ate my Jell-O in the dark medieval dining room, which was hung all around with colorful knights’ shields, I repeatedly checked Dad’s watch. We needed to get home before Wonderful World of Disney came on.

Never was this so urgent than the night in October when they broadcast “The Legend of Sleepy Hollow.”

If I was lucky I saw it twice – once on TV, and again when they herded every kid in Foster Elementary into the gym and screened it in 16mm. We had been making construction paper cats and witches and ghosts since the end of September. But it wasn’t Halloween till I saw “The Legend of Sleepy Hollow.” That was when it really began. That Disney film was, and still is, the portal by which I reach the heart of the holiday. The kids-in-costumes, plastic-mask-held-on-by-rubber-bands, smell-of-burned-pumpkin-lid, sound-of-candy-dropped-in-a-bag Halloween.

Everything about “The Legend of Sleepy Hollow” I consider to be perfect. The fall colors, the narration by Bing Crosby, the disarmingly cute opening and the scary end. Brom Bones’ song at the Van Tassels’ Halloween party always make me feel like I was there amongst the frightened guests. And the execution of Ichabod’s final, lonely ride through the deep woods and hidden graveyards of his township is a masterpiece of tension, humor, and sudden terror.

ichabod-1200

And the characters! There is only one Ichabod, and certainly Brom Bones is the ironclad prototype from which Beauty and the Beast‘s Gaston was later hammered.

But none of it would work if not for Katrina. Presented as an unearthly beauty who arrives out of nowhere at the side of her father, she is a creature that only animation could conceive, floating around like a cloud, prancing across streams more like Bambi than a human being. Katrina lifts nothing heavier than a teacup or parasol while a willing army of admirers carry entire picnics and weeks of provisions for her. And yet she never came off as manipulative to me. Rather, Katrina seemed to occupy a needed space in that world. Like a thunderstorm that sweeps through the mountains, she was a disruptive necessity. She kicked everyone into gear. She was the planet all the other characters fall into orbit around.  I like that Katrina messes with people, but in the end she, like Brom Bones, is without malice. Her willingness to toy with Ichabod is in direct proportion to the less-than-noble designs Ichabod has for her.  This fantastic little story by Washington Irving recognizes both Brom’s and Katrina’s awareness of their inevitable pairing, thus this last dance of courtship choreographed by Katrina.  In a situation like this any of these three characters could have come off as a victim or a villain, but in the hands of this particular team of artists they all end up quite likable, indeed.  No one, I think, more than Katrina. She’s beautiful and provocative at her entrance, and even moreso at the finish.  I wish she showed up in attractions and merchandise more than she currently does. Which is to say not at all – save for an often overlooked restaurant in Walt Disney World.

Katrina is, I think, unique amongst Disney characters. She exudes more dimension, charm and attitude than a character with her screen time has a right to. And all without uttering a single word. And the unapologetic audacity of her design is refreshing. Jessica Rabbit gets a lot of attention for how she’s drawn, but I think Katrina has her beat in all categories. Katrina’s animators include Frank Thomas, Ollie Johnston, John Lounsbery, Ken O’Brien, Woolie Reitherman, John Sibley, and, of course, Fred Moore.  I’m not sure if a featurette usually had such an all-star lineup, but this film obviously owes a good deal of its longevity and strength to its roster.  But a huge amount of credit should be given to the story crew, the background painters, and the editing and sound work in the climactic sequence.

So what’s the point of all this? I guess I just want to keep the memory of this cartoon alive. A new generation shouldn’t miss out on this perfect piece of American Halloween. Take an hour to share “The Legend of Sleepy Hollow” with someone you think would like it. You can find it on Netflix (although not streaming, sadly) and Amazon Instant Video, or even newly bundled on DVD and Blu-ray.

And Happy Halloween!
