Another day, another 3D printer. This time we have a model
that comes from SUNY Purchase College where they are working on a
laser-cut, compact 3D printer that can make extra tall models simply by
swapping out a few pieces.
The printer pumps out plastic at 100 microns, a more than acceptable
resolution, and uses very few moving parts. You’ll notice that the print
head rides up three rails. This would allow you to add longer bars or
extensions to bring things bigger than the platform.
Created by students Shai Schechter, Andrey Kovalev, Yasick Nemenov
and Eugene Sokolov, the project is currently in pre-beta and they aim to
launch a crowdfunding campaign in November. You can sign up for updates here.
The team hopes to make the product completely open source and because
it uses very few expensive parts they’re able to price it very
aggressively. While I love projects like these, I’m anxious to see how
they build their software – one of the most important parts of a 3D
printing package. As long as it’s solid I’d totally be down with this
cool rig.
Qualcomm, the founding member of Alliance for Wireless Power (or A4WP in short), made a surprise move today by joining the management board of the rival Wireless Power Consortium (or WPC), the group behind the already commercially available Qi
standard. This is quite an interesting development considering how both
alliances have been openly critical of each other, and yet now there's a
chance of seeing just one standard getting the best of both worlds.
That is, of course, dependent on Qualcomm's real intentions behind
joining the WPC.
While Qi is now a well-established ecosystem backed by 172
companies, its current "first-gen" inductive charging method is somewhat
sensitive to the alignment of the devices on the charging mats (though
there has been recent breakthrough).
Another issue is Qi can currently provide just up to 5W of power (which
is dependent on both the quality of the coil and the operating
frequency), and this may not be sufficient for charging up large devices
at a reasonable pace. For instance, even with the 10W USB adapter, the
iPad takes hours to fully juice up, let alone with just half of that
power.
Looking ahead, both the WPC
and the 63-strong A4WP are already working on their own magnetic
resonance implementations to enable longer range charging. Additionally,
A4WP's standard has also been approved for up to 24W of output, whereas
the WPC is already developing medium power (from 15W) Qi specification
for the likes of laptops and power tools.
Here's where the two standards differentiate. A4WP's implementation
allows simultaneous charging of devices that require different power
requirement on the same pad, thus offering more spacial freedom.
On the other hand, Qi follows a one-to-one control design to maximize
efficiency -- as in the power transfer is totally dependent on how much
juice the device needs, and it can even go completely off once the
device is charged.
What remains unclear is whether Qualcomm has other motives behind its
participation in the WPC's board of management. While the WPC folks
"encourage competitors to join" for the sake of "open development of
Qi," this could also hamper the development of their new standard. Late
last year, we spoke to the WPC's co-chair Camille Tang (the name "Qi"
was actually her idea; plus she's also the president and co-founder of
Hong Kong-based Convenient Power), and she expressed concern over the
potential disruption from the new wireless power groups.
"The question to ask is: why are all these groups now coming out and
saying they're doing a standard? It's possible that some people might
say they really are a standard, but they may actually not intend to put
products out there," said Tang.
"For example, there's one company with their technology and one thing
that's rolling out in infrastructure. They don't have any devices, it's
not compatible with anything else, so you think: why do they do that?
"It's about money. Not just licensing money, but other types of money as well."
At least on the surface, Qualcomm is showing its keen side to get
things going for everyone's best interest. In a statement we received
from a spokesperson earlier, the company implied that joining the WPC's
board is "the logical step to grow the wireless power industry beyond
the current first generation products and towards next generation,
loosely coupled technology." However, Qualcomm still "believes the A4WP
represents the most mature and best implementation of resonant
charging."
The 5S features a fingerprint sensor, has an upgraded camera, and contains an A7 chip Photo: Justin Sullivan/Getty Images
Hackers from around the world have put together more than $15,000
they hope will be enough to entice the smartest hackers to break into
the new iPhone’s much-lauded fingerprint scanner.
The iPhone 5S, which was announced last week, features a fingerprint
scanner to unlock the device and make purchases. Apple has said that an
image of the fingerprint is not stored on the device, but only the data
to recognize the fingerprint when it is pressed on the sensor.
Security experts quickly grew suspicious after the product was
annouced, though. It is, after all, far easier to change a compromised
password than a compromised fingerprint if the data were to get into the
wrong hands.
To test Apple’s security claims, hackers are taking the challenge global.
The campaign is being run through IsTouchIdHackedYet.com, where individuals can put up their own money to reward the winner of the challenge.
The amount currently being offered is in excess of $15,000.
To win the prize, someone must be able to demonstrate that they:
Can lift a fingerprint from the iPhone 5S
Reproduces the fingerprint
Use the reproduced fingerprint to unlock the iPhone 5S in fewer than 5 attempts
It’s no small challenge.
Apple says the information gathered by the phone is not an image of
the fingerprint but an encrypted pile of data points that describe the
fingerprint. They’ve also said that the information is stored deep
within the phone and will be extremely difficult for anyone, including
Apple, to access. They’ve also said that the fingerprint data will not
be transmitted from the phone in any capacity.
This effectively means that winners of the prize will most likely try
to dust the phone itself for fingerprints and try to replicate the
finger by creating some kind of physical caste of the print to be used
on the scanner.
I am pleased to announce that we released the Kinect for Windows
software development kit (SDK) 1.8 today. This is the fourth update to
the SDK since we first released it commercially one and a half years
ago. Since then, we’ve seen numerous companies using Kinect for Windows
worldwide, and more than 700,000 downloads of our SDK.
We build each version of the SDK with our customers in mind—listening
to what the developer community and business leaders tell us they want
and traveling around the globe to see what these dedicated teams do, how
they do it, and what they most need out of our software development
kit.
The new background removal API is useful for advertising, augmented reality gaming, training and simulation, and more.
Kinect for Windows SDK 1.8 includes some key features and samples that the community has been asking for, including:
New background removal. An API removes the
background behind the active user so that it can be replaced with an
artificial background. This green-screening effect was one of the top
requests we’re heard in recent months. It is especially useful for
advertising, augmented reality gaming, training and simulation, and
other immersive experiences that place the user in a different virtual
environment.
Realistic color capture with Kinect Fusion. A new
Kinect Fusion API scans the color of the scene along with the depth
information so that it can capture the color of the object along with
its three-dimensional (3D) model. The API also produces a texture map
for the mesh created from the scan. This feature provides a full
fidelity 3D model of a scan, including color, which can be used for full
color 3D printing or to create accurate 3D assets for games, CAD, and
other applications.
Improved tracking robustness with Kinect Fusion.
This algorithm makes it easier to scan a scene. With this update, Kinect
Fusion is better able to maintain its lock on the scene as the camera
position moves, yielding a more reliable and consistent scanning.
HTML interaction sample. This sample demonstrates
implementing Kinect-enabled buttons, simple user engagement, and the use
of a background removal stream in HTML5. It allows developers to use
HTML5 and JavaScript to implement Kinect-enabled user interfaces, which
was not possible previously—making it easier for developers to work in
whatever programming languages they prefer and integrate Kinect for
Windows into their existing solutions.
Multiple-sensor Kinect Fusion sample. This sample
shows developers how to use two sensors simultaneously to scan a person
or object from both sides—making it possible to construct a 3D model
without having to move the sensor or the object! It demonstrates the
calibration between two Kinect for Windows sensors, and how to use
Kinect Fusion APIs with multiple depth snapshots. It is ideal for retail
experiences and other public kiosks that do not include having an
attendant available to scan by hand.
Adaptive UI sample. This sample demonstrates how to
build an application that adapts itself depending on the distance
between the user and the screen—from gesturing at a distance to touching
a touchscreen. The algorithm in this sample uses the physical
dimensions and positions of the screen and sensor to determine the best
ergonomic position on the screen for touch controls as well as ways the
UI can adapt as the user approaches the screen or moves further away
from it. As a result, the touch interface and visual display adapt to
the user’s position and height, which enables users to interact with
large touch screen displays comfortably. The display can also be adapted
for more than one user.
We also have updated our Human Interface Guidelines (HIG) with
guidance to complement the new Adaptive UI sample, including the
following:
Design a transition that reveals or hides additional information without obscuring the anchor points in the overall UI.
Design UI where users can accomplish all tasks for each goal within a single range.
My team and I believe that communicating naturally with computers
means being able to gesture and speak, just like you do when
communicating with people. We believe this is important to the evolution
of computing, and are committed to helping this future come faster by
giving our customers the tools they need to build truly innovative
solutions. There are many exciting applications being created with
Kinect for Windows, and we hope these new features will make those
applications better and easier to build. Keep up the great work, and
keep us posted!
MakerBot
is best known for its 3D printers, turning virtual products into real
ones, but the company’s latest hardware to go on sale, the MakerBot
Digitizer, takes things in the opposite direction. Announced back in March,
and on sale from today for $1,400, the Digitizer takes a real-world
object and, by spinning it on a rotating platform in front of a camera,
maps out a digital model that can then be saved, shared, modified, and
even 3D printed itself.
Although the process itself involves some complicated technology and
data-crunching, MakerBot claims that users themselves should be able to
scan in an object in just a couple of clicks. The company includes its
own MakerWare for Digitizer software, which creates files suitable for
both the firm’s own 3D printers and generic 3D files for other hardware.
Calibration is a matter of dropping the included glyph block on the
rotating platter and having the camera run through some preconfigured
tests. After that, you center the object you’re hoping to scan,
selecting whether they’re lightly colored, medium, or dark, and then
waiting until the process is done.
MakerBot Digitizer Desktop 3D Scanner overview:
That takes approximately twelve minutes per
object, MakerBot says, so don’t think of this as the 3D scanner
equivalent of a photocopier. The camera itself runs at 1.3-megapixels
and is paired with two Class 1 lasers for mapping out objects, and the
overall resolution is good for 0.5mm in terms of detail and +/- 2.0mm
for dimensional accuracy. Maximum object size is up to 20.3cm in
diameter and the same in height.
Once you’ve actually run something through the scanner, the core grid
file can be shared directly from the app to Thingiverse.com, or edited
and combined with other 3D files to make a new object altogether.
The MakerBot Digitizer Desktop Scanner is available for order now, priced at $1,400.
GAMES CONSOLE AND PHONE MAKER Microsoft has hinted that it will bring its Xbox Kinect camera technology to its Windows Phone 8 mobile operating system following its acquisition of Nokia.
During a conference call on Tuesday, Microsoft operating systems
group VP Terry Myerson hinted that the firm will work with Nokia to
integrated Kinect camera technology into future Windows Phone devices.
Speaking about the Nokia buyout, Myerson said, "In the area of imaging, the Nokia Lumia 1020 has no equal. We are excited to bring this together with our Kinect camera technology to delight our customers."
Myerson didn't elaborate further, so it's unclear when Microsoft will
introduce this technology and what it will be capable of doing.
However, this isn't the first we've heard about Kinect technology
possibly coming to Windows Phone devices. Previous rumours had
speculated that the integration will allow users of Windows Phone
devices to control their handsets using both voice and gestures.
It's possible that the Kinect integration could also enable more
immersive gaming on Windows Phone devices and facilitate deeper
integration with Microsoft's Xbox One games console.
While all this sounds promising, Kinect integration could also be a
bad thing for the Windows Phone ecosystem, with Microsoft having been
accused of spying on its users with Kinect in the wake of recent NSA
surveillance revelations.
