IFA: Sony Xperia Z3 hands-on review

04 Sep 2014

BERLIN: Sony lifted the lid on its Xperia Z3 smartphone, at IFA on Wednesday, with its updated slimmer design, solid aluminium frame and rounder edges than its predecessor the Xperia Z2. We were lucky enough to have some hands-on time with the device before its launch.

Design
The first noticeable thing about the Xperia Z3 is that it is thinner and lighter than the Xperia Z2. It was clear that Sony has managed to squeeze in a number of updates, such as a slimmer chassis that feels more comfortable to hold.

IFA - Sony unveils Xperia Z3 smartphone

The Xperia Z3 is very similar to the Xperia Z2, which in terms of design is no bad thing as we're fans of the boxy look. Even better, with this release Sony has rounded the edges even further, making the Z3 easier to hold, while still managing to pack the same sized 5.2in screen into the bezel.

The firm has made it slimmer by 0.9mm, so it now measures just 7.3mm, compared with the Xperia Z2's 8.2mm. Picking up the phone for the first time, we were surprised at how comfortable it felt, even with such a large display.

Another great feature of the Xperia Z3's design is that – like the Xperia Z2, Xperia Z1 and Xperia Z before that – the Xperia Z3 can be dunked in water for up to 30 minutes at a depth of 1.5m, Sony claims. This is thanks to its dust-resistant and waterproof IP65 and IP68 certification, the highest possible waterproof rating. However, we didn't have a chance to test that in our brief time with the device.

Screen
The display on the Sony Xperia Z3 is its most impressive feature. With the same pixel count as its 1080x1920 resolution predecessor, the Xperia Z3's 5.2in display blew us away. Images are crystal clear and it is truly stunning to use: both text and images look sharp and touch operations are smooth between pages and apps.

Performance and software
The Sony Xperia Z3 is powered by a quad-core 2.5GHz Qualcomm Snapdragon 801 processor with 3GB of RAM, making it quite a powerhouse. The chip is just as impressive in the real world as it is on paper, and we found the device very nippy, with no lag whatsoever, even when playing and recording 4K video, though during the latter it does still get a little hot.

As for software, the Xperia Z3 runs Google's Android 4.4 Kitkat mobile operating system right out of the box. However, Sony has skinned Android with its own custom user interface (UI). While we've never been huge fans of Sony's custom UI, finding it overbearing compared with a vanilla Android user interface, some of the firm's apps are a bonus.

The Xperia Z3 also arrives loaded with Sony's Walkman and PlayStation companion apps as seen on the Xperia Z2, as well as many new augmented-reality camera features and built-in noise cancellation technology to help block out background sounds while listening to music.

Camera
Perhaps the most impressive feature of the Xperia Z3 is its rear-facing camera, which not only features the same 20.7MP sensor as seen in its predecessor and the same 4K video recording, but it also boasts an 'Exmor RS for mobile' image sensor, with a new 25mm G Lens, making it what Sony claims "the world's first smartphone with ISO 12800 sensitivity for superior photos, even in low light."

Still images taken with the 20.7MP camera were just as impressive as on the Xperia Z2, appearing crisp, clear and full of natural colour.

The Sony Xperia Z3 also features a 2.2MP camera on its front that's capable of shooting HD 1080p video for all your video-calling needs.

Overall
Our first impressions of the Sony Xperia Z3 were good, but the handset's success will likely depend in part on its cost, which has not yet been announced.

Sony will release the Xperia Z3 around the world this autumn. Check back with V3 then for our full review.

Samsung Gear S hands-on review

04 Sep 2014

Technology firms have been trying to persuade us we need smartwatches for quite some time. However, a number of niggling flaws in past smartwatches – including their need to be tethered to a smartphone to work and woefully small displays – have stopped many people, including us here at V3, from getting excited about them.

Samsung claims to have gone back to the drawing board to design its Gear S smartwatch, and has worked to fix all our past qualms and finally offer users the wearable wrist companion they've been waiting for.

Design and build
The Gear S's curved screen and metallic design features make it look about as slick as a smartwatch can be.

As well as making the wearable look slick, the curved chassis also makes the device feel significantly more comfortable to wear than many of the other smartwatches we've experienced, for example the LG G Watch, which has a flat back.Samsung Gear S IFA

The one potential design flaw we noticed is that, like most smartwatches, the Gear S is noticeably larger than most regular watches. We're used to wearing big watches, so we found the 40x58x12.5mm Gear S' dimensions weren't too much of an issue, but people used to regularly sized watches may find it slightly cumbersome.

Despite being large the Gear S is fairly well built regarding its specs, and it meets IP67 certification standards. This means the Gear S should be dust and water resistant and should be able to survive submersions in up to one metre of water for 30 minutes.

Sadly the Samsung spokesperson on hand at the event declined our request to test the Gear S's water resiliency and all but tore it off our wrist when asked we if we could pour our bottle of water over it.

Display
During our hands on we found the Gear S's 2in, 360x480 pixels, 300ppi Super Amoled capacitive touchscreen was one of the best we'd ever seen on a smartwatch. Using Samsung's Super Amoled screen tech, colours on the Gear S display were wonderfully vibrant and it was brilliantly bright. We'll be interested to see if our positive impressions remain when we test the Gear S in more adverse lighting conditions, such as direct sunlight, which has rendered all past smartwatches close to unusable.

Software
Unlike most 2014 smartwatches the Gear S runs using Samsung's own Tizen operating system, not Google's newly launched Android Wear. Scrolling through various menus we found Tizen offers a significantly different user experience to Android Wear and has a completely different menu and application system.

Unlike Android Wear, Tizen's user interface (UI) requires you to swipe left or right to switch between applications and services. Google's OS by comparison requires you to scoll up and down. Tizen applications' individual interfaces are also far more varied than those seen on Android Wear, which have a uniform card-like design similar to that seen on Google Now.Samsung Gear S calendar app

For example, moving from a weather app, which featured a familiar UI to Android's to a Tizen news aggregator we were met with a completely different tiled design reminiscent of HTC's BlinkFeed that had its own set of shortcuts and colour palette.

While we initially found the experience a little jarring and disjointed, we soon became accustomed and began to notice a number of positive points about Tizen.

For one, many of the apps we used had noticeably more advanced functionality than their Android Wear equivalents. For example, entering the calendar app, we could not only see incoming notifications, but we could also tweak or create new ones directly from the Gear S, which we couldn't do on Android Wear smartwatches.

Productivity perks are aided by the fact it has standalone 3G and WiFi connectivity. This means, after requiring you to pair the smartwatch with a smartphone on setup, the Gear S can function independently and doesn't require a constant Bluetooth connection to an Android handset.

Performance
The Gear S is powered by an unspecified dual-core 1GHz processor and 512MB of RAM. While we found these features were more than good enough in past smartwatches, during our hands on we noticed the Gear S did occasionally chug and stutter.Samsung Gear S news app

For example, going through the news feed on an aggregator app, the Gear S occasionally stalled for a fraction of a second when we tried to scroll up or down. Though being fair to Samsung, the Gear S we tried was a pre-production model and this issue could equally be due to poor coding on the app itself and in general the Gear S performed very well during our hands on.

Battery
Battery power is a constant issue on all the smartwatches we've encountered, with most barely lasting a full day's use before needing a top-up charge. Sadly we didn't get a chance to test the Gear S battery life. However, if Samsung's claim the Gear S 300mAh battery will offer users "two full days of typical usage", it will be above average for a smartwatch.

Overall
While the Gear S doesn't follow the common path of most manufacturers and uses Samsung's Tizen OS, as opposed to the increasingly common Android Wear, it did impress us.

Featuring a curved design that makes the Gear S look nice and feel comfortable on your wrist, a sizable 2in display and standalone 3G connectivity, there is plenty to like about Samsung's latest smartwatch.

Hopefully the minor performance issues we noticed during our hands on will have disappeared by the time the Gear S arrives in the UK later this year, and tech aficionados across the globe will finally have the smart smartwatch they've been waiting for.

Galaxy Note 4 hands-on review

03 Sep 2014

BERLIN: Samsung claims it created the plus-sized "phablet" market in 2011 when it unveiled its first Galaxy Note. While technically this was actually Dell with its Streak 5 in 2010, Samsung is without a doubt the first smartphone manufacturer to successfully push big handsets to the masses and, in many buyers' minds, the Galaxy Note range is still the first anyone thinks of when shopping for a big-screen device.

As a result, at the Galaxy Note 4's unveiling at Samsung's IFA Unpacked 2014 keynote in Berlin, we couldn't resist the chance to get some hands on time with the gargantuan handset.

Design and build
Visually the Galaxy Note 4 doesn't stray too far from its predecessor, the Galaxy Note 3 and has the same fake leather backplate and metallic sides. The Galaxy Note 4's button placement is also the same and the Galaxy Note 4 has a physical front-facing home button and volume and power controls on its right side. Under the hood, though, Samsung has made a few changes, one of the biggest of which is the inclusion of the custom fingerprint scanner debuted on Samsung's regular-sized Galaxy S5 handset.Samsung Galaxy Note 4 home screen

The scanner is a bonus for enterprise customers as it lets them lock the Galaxy Note 4 to only unlock once they have proven their identity, making it much harder for criminals to access corporate data stored on the phone should it be lost or stolen.

While the Galaxy Note 4 is fairly thin by phablet standards, despite years of wielding the plus-sized handsets, we still found the phone's 154x79x8.5mm dimensions and 176g weight slightly cumbersome when trying to use the device one handed.

Luckily these issues are heavily countermanded by the inclusion of the Galaxy Note 4's reworded S Pen. The S Pen digital stylus docks into the bottom edge of the Galaxy Note's rear, and helps make the Galaxy Note 4 more comfortable to use, despite it's advanced size, for a variety of reasons. More on this later.

While we didn't get to drop test the Galaxy Note 4 during our hands on we were reasonably impressed with its build quality. The handset felt solidly built and left us feeling suitably assured it could survive the odd accidental drop chip and scratch free.

Display
As we've seen in past Samsung handsets, the Galaxy Note 4's 5.7in QHD 2560x1440 Super Amoled display is one of its best features. While we only got to test the display in the controlled showroom floor lighting conditions we found the Galaxy Note 4's display is not only crisp, but also features great colour balance and brightness levels – so much so that we had to turn the demo unit's brightness setting down.

This is likely a consequence of Samsung's custom Super Amoled technology. Super Amoled is good as not only does it offer all the benefits of normal Amoled screens, which are designed to display deeper and richer blacks by electrically charging each individual pixel to generate colours, it also reduces the screen's power consumption.

The technology reduces power consumption by integrating the capacitive touchscreen layer directly into the display instead of overlaying it on top, as with regular Amoled screens. The practice removes the need to charge two components at once, thus reducing the display's power consumption.

Operating system and software
The Galaxy Note 4 runs using a heavily customised version of Android 4.4.4 KitKat. In the past we've not been massive fans of Samsung's software additions as they, generally, add a wealth of needless services and make handsets' user interfaces (UIs) feel busy and slightly unpleasant to use.

But we were fairly impressed by how much work Samsung has put in to fix these issues. As well as featuring significantly fewer bloatware applications than the Galaxy Note 3, the Galaxy Note 4's main UI also looks noticeably cleaner.

We were also happy to see Samsung has developed some of the more pleasant and useful software additions it has made over the years, loading the Galaxy Note 4 with a wealth of applications designed to help users take advantage of its S Pen Stylus, for example.

Key positive additions we noticed are the Galaxy Note 4's enhanced multi-window support and new Smart Select and S Pen Mouse features.Samsung Galaxy Note 4 S Pen

The reworked multi-window feature lets users swipe using the S Pen to minimise open windows and pull up new apps, while Smart Select is an innovative feature that lets users select several pieces of content in a row and simultaneously share them as attachments in messages. S Pen Mouse is designed to make it easier to select and edit text using the S Pen and lets users instruct the stylus to highlight text simply by holding down the pen's side button.

During our time with the Galaxy Note 4 we were very impressed by how well the features worked and found they made key productivity tasks, such as document-editing, note-taking and altering images, significantly easier to do than they are on most competing handsets.

There is some truth to Samsung's claims that the Galaxy Note 4's S Pen stylus is twice as pressure sensitive as the Note 3's and felt it was significantly more accurate and reactive than its predecessor.

Performance
On paper the Galaxy Note 4 is one of the most powerful handsets out there and runs using a Qualcomm Snapdragon 805 processor and 3GB of RAM. We didn't get a chance to properly benchmark the Galaxy Note 4, or see how it coped with demanding tasks such as 3D gaming during our hands on, but found for general purposes it is very quick.

The Galaxy Note 4 opened applications and webpages in milliseconds and ran chug and stutter free, even when we had multiple apps running using the handset's multi-window support.

Camera
Samsung made a big deal about the Galaxy Note 4's 16MP, 3456x4608 rear camera with optical image stabilisation, and 3.7MP front camera, claiming they will offer users "industry-leading" imaging quality.

Testing them on the show floor, while still not of the same quality as images taken on the Nokia Lumia 1020, images taken on the Galaxy Note 4 were very crisp and featured great contrast and brightness levels.Samsung Galaxy Note 4 back

Running through the camera app's options, it is reasonably well stocked and supports all the modes you'd expect, including Dual Shot, panorama and HDR (high dynamic range).

While we're still not convinced many executives would use the Galaxy Note 4's 3.7MP front camera for anything but video calling, we were also reasonably impressed with its imaging quality and found it is reasonably good at taking photos.

Storage
The Galaxy Note 4 we tested came with 32GB of internal storage. Luckily for those looking for more space, a further 64GB can be added using the Galaxy Note 4's micro SD card slot.

Overall
Featuring a large, but crisp display and offering what appears to be top-end performance and a reworked more sensitive S Pen stylus, our opening impressions of the Galaxy Note 4 are very positive and the device certainly has the potential to be one of 2014's best handsets.

However, with Samsung yet to reveal the Galaxy Note 4's UK release date and price, it's currently difficult to gauge whether it will make good on this promise.

Check back with V3 later for a full review of the Samsung Galaxy Note 4.

Boston shows off servers and workstations with upcoming Intel Xeon E5-2600 Haswell-EP processors

22 Aug 2014

Intel is preparing to release its next generation Xeon processors for workstations and servers, and many vendors are gearing up with new systems in the pipeline ready to launch when the chips themselves are officially available.

One such firm is Boston Limited, which allowed us a preview of some of the updated systems it has waiting in the wings until the official launch date, which is coming in the near future.

Boston has a close relationship with Supermicro, and many of its systems are based on chassis designs from that vendor, with the firm offering to custom build solutions for specific requirements.

On the server side, Boston is readying a 1U rack-mount "pizza box" system, the Boston Value 360p (pictured below). This is a two-socket server with twin 10Gbps Ethernet ports, support for 64GB memory and 12Gbps SAS Raid. It can also be configured with NVM Express (NVMe) SSDs connected to the PCI Express bus rather than a standard drive interface.

boston-1u-rack

Boston also has a multi-node rack server, the Quattro 12128-6 (pictured below), which comprises four separate two-socket servers inside a 2U chassis. Each node has up to 64GB memory, with 12Gbps SAS Raid storage plus a pair of 400GB SSDs.

boston-2u-rack

On the workstation side, Boston is readying a mid-range and a high-end system with the new Intel Xeon chips, both based on two-socket Xeon E5-2600v3 rather than the single socket E5-1600v3 versions.

The mid-range Venom 2301-12T (pictured below) comes in a similar mid-tower chassis to the system we reviewed last year, and likewise ships with an Nvidia Quadro K4000 card for graphics acceleration. It comes with 64GB of memory and a 240GB SSD as a boot device, plus two 1TB Sata drives configured as a Raid array for data storage.

boston-mid-ws

For those needing a bit more performance, the Venom 2401-12T (below) ships with faster Xeon processors, 128GB memory, and an Nvidia Quadro K6000 adapter. This also has a 240GB SSD as a boot drive, with two 2TB drives configured as a Raid array for data storage.

boston-ent-ws

The Venom 2401-12T also features the CoolIT liquid cooling system attached to its processor heatsinks, enabling them to run at full clock speed for longer, according to Boston.

Finally, the new Xeon E5-2600v3 processors are designed to work with 2133MHz DDR4 memory instead of the more usual DDR3. The last picture here (above) shows a DDR3 DIMM next to a DDR4 DIMM. The DDR4 has slightly longer connectors towards the middle of the module.

Raspberry Pi Model B+ opening impressions

14 Jul 2014

The Raspberry Pi Foundation unveiled the latest redesign of its Raspberry Pi single-board computer on Monday, as detailed by V3. The update adds a number of features but is still available at the same price from outlets such as RS Components and Farnell Element14.

Farnell Element14 was showing the device at an official launch event in London, and we went along to have a look at the new model.

Raspberry Pi Model B Plus

The Raspberry Pi Model B+ is the same size and shape as the older Model B, as can be seen in the photo of both devices next to each other (below).

Raspberry Pi Model B and Model B plus

However, the new device has a number of changes, including more USB ports and a larger I/O header connector, which can also be seen in the pictures.

Having four rather than two USB ports enables more devices to be connected. On the older Pi, you could easily use up both plugging in a mouse and keyboard, unless you happened to have a USB hub or a keyboard that can daisy chain the mouse through it.

Another less visible update is to the power supply. A redesigned power regulator circuit can supply more current to the USB ports, up to a maximum of 1.2A across all four ports, enabling hardware such as USB hard drives to be powered from the Raspberry Pi, as in the picture below.

Raspberry Pi Model B Plus with external hard drive

According to Element 14, this will be a boon for projects where the Raspberry Pi is being used to drive a sensor and record data from it, as the device can now have access to much greater storage than is available on an SD card.

Element 14 also showed off a new Raspberry Pi case the firm is selling via its website. Not only is this £4.76 accessory designed to snugly fit the new Model B+ device, but also the Raspberry Pi camera module (see below) that connects into the dedicated CSI connector on the Pi board.

Raspberry Pi Model B Plus case open

We will report back at a later date with a more in-depth look at the new Raspberry Pi Model B+.

Surface Pro 3 vs Surface Pro 2

09 Jul 2014

Since Microsoft first entered the tablet hardware market in 2012 it has been promising users the world, claiming its Surface series of devices would be able to function equally well as both tablet and laptop.

But because of a number of niggling flaws in the first two Surface Pro tablets' design and software, they fell somewhere between the two categories and didn't fully deliver on Microsoft's promise.

As a result, when Microsoft returned to the stage earlier in May to unveil its latest Surface Pro 3 shouting the same message as before, some buyers were justifiably skeptical.

Since then these doubts have grown and many buyers have been wondering exactly what changes have been made to differentiate the Surface Pro 3 from its predecessor, the Surface Pro 2, to let it deliver on Microsoft's "one device to rule them all" promise.

Design and build
The Surface Pro 3 features a completely reworked design to previous Surface devices, with Microsoft having worked to make its new tablet as light and thin as possible.

During our tests we were impressed with the Surface Pro 3's design and found the light aluminium tablet-laptop hybrid looks a lot sharper than its predecessor. Despite featuring a larger display the Surface Pro 3 is significantly lighter and thinner than the Surface Pro 2, measuring in at 292x201x9.1mm and weighing 800g.Microsoft Surface Pro 3 three-quarter

The Surface Pro 3

We found the thinner and lighter design makes the Surface Pro 3 feel significantly more travel friendly and comfortable to use as a tablet than the 274x173x13.5mm, 907g Surface Pro 2.

What's more impressive, though, is that even though the Surface Pro 3 has less real estate along its sides, Microsoft has still managed to load it with USB 3.0 micro SD and Mini DisplayPort inputs.

Adding the new Type Cover and putting the Surface Pro 3 in laptop mode, we were equally impressed during our early tests. Unlike the Surface Pro 2, which has a kickstand that only features two standing options, the Surface Pro 3 can be manually adjusted to stand at custom angles.

While this sounds small, it's a serious upgrade. The ability to set which angle the Surface Pro 3 stands at not only makes it easier to rest and use the device on your lap, this also makes it more pleasant to use when doing tasks such as digital painting with the device's stylus. This is because the new kickstand let us set the Surface Pro 3 to sit at the same angle as a proper drawing board or Wacom tablet PC when doodling.

Microsoft has done some good work to improve the Surface Pro 3 Type Cover's trackpad. The Surface Pro 2 Type Cover's trackpad was one of its worst features, being too small for comfortable use and featuring unresponsive capacitive right and left click buttons. Microsoft has worked hard to fix this on the Surface Pro 3's Type Cover and has made the trackpad significantly larger and added physical left- and right-click buttons.Microsoft's Surface Pro 2 overall

The Surface Pro 2

During our hands on we were impressed by how much more responsive the Surface Pro 3's Type Cover was than the Pro 2's, making it easier to use as a laptop replacement when editing Word documents or loading copy into a content management system, for example.

Display
Microsoft made a lot of fuss about the Surface Pro 3's 12in ClearType Full HD 2160x1440 resolution screen at the device's launch. Specifically Microsoft claims that, as well as being 38 percent bigger than the Surface Pro 2's 10.6in ClearType Full HD 1920x1080 resolution screen, the Surface Pro 3's 12in display is able to display twice as many pixels.

During our hands on, we did notice a clear difference in quality between the two tablets' displays and found the Surface Pro 3 is significantly sharper and clearer. That said, we did notice, like the Surface Pro 2, the Surface Pro 3's display is still slightly prone to picking up stray light.

Software
Both the Surface Pro 3 and Surface Pro 2 run using the latest version of Microsoft's Windows 8.1 operating system. This means users will have access to key Microsoft security and productivity services, such as Office, OneDrive, OneNote and Lync.

But thanks to the inclusion of the Surface Pro 3's upgraded digital stylus, it is easier and more pleasant to take advantage of the services than it is on Microsoft's previous tablet. Unlike the Surface Pro 2's polycarbonate digitiser stylus, the Surface Pro 3 is made of metal and features a number of improved shortcut features.Microsoft Surface Pro 3 flat

OneNote is a good example of this. Unlike the Surface Pro 2, OneNote can be activated at any time, even when the tablet is in sleep mode, simply by pressing down on the stylus's rear button. Once activated the app offers a blank page for Surface Pro users to scribble notes on, and a second push of the rear button will save the notes to the user's OneDrive cloud storage account. Little touches like this made the Surface Pro 3 feel slightly slicker and easier to use than its predecessor. Hopefully we'll find more nice touches when we write our full review.

Processor
Unlike the Surface Pro 3, which is available in Intel Core i3, i5 and i7 options, the Surface Pro 2 is only available with an i5 chip. Microsoft claims that the top Intel Core i7 Surface Pro 3 option will offer 10 percent better performance than the Surface Pro 2. Sadly we didn't get a chance to test Microsoft's claim as the demo unit we tested was powered by an Intel i5 Haswell processor. We didn't get a chance to see how the Surface Pro 3 performed with demanding tasks, such as large digital painting projects or 3D gaming, but found it was nippy and responsive when doing basic tasks such as word processing.

Camera
Microsoft claims the Surface Pro 3's upgraded 5MP rear-facing camera will offer radically better imaging performance than the Surface Pro 2's 3.5MP unit. Sadly we didn't get a chance to test the Surface Pro 3's camera during our hands on, but will be sure to in our full review.

Storage and battery
Both Surfaces feature the same 64GB, 128GB, 256GB, 512GB internal storage options, though Microsoft lists the Surface Pro 3 as being able to last a full hour longer than its predecessor, listing it as offering up to nine hours of web browsing off one charge.Microsoft's Surface Pro 2 kickstand angle one

Price
Thanks to its more varied chip offering the Surface Pro 3 is the more affordable option, with prices starting at £639 for the 64GB Intel Core i3 model. By comparison the 64GB Surface Pro 2 costs £720.

Overall
Having had an opening look at the Surface Pro 3 we are very impressed. Featuring a radically improved, slimmer and lighter design, a more varied array of processor options and a larger and clearer display the Surface Pro 3 feels like a serious step up from previous Microsoft tablets.

From what we've seen the Surface Pro 3 has the potential to finally make good on Microsoft's "one device to rule them all" promise. Hopefully our positive impressions will ring true once we put the Surface Pro 3 more thoroughly through its paces in our full review later this year.

RS Components shows off new 3D printers

01 Jul 2014

RS Components last week showed off a number of the 3D printers in its line-up, including newly available models from 3D Systems that enable users to print objects comprised of more than one colour. At the same event, Dr Adrian Bowyer, inventor of the RepRap, the first low-cost 3D printer, gave a talk about the implications that 3D printing may hold for manufacturing and society in general.

On show at the event in London was the RepRapPro Ormerod, the most up-to-date version of the RepRap device, along with newly available models from 3D Systems, including the third-generation Cube, and the CubePro Duo and CubeX Trio.

The third-generation Cube (below) supports simultaneous printing of two plastic colours, and can fabricate objects up to 152x152x152mm in volume. It is available from RS for £999.

3D Systems Cube 3rd gen

Meanwhile, the larger CubePro model has a fully enclosed print area for a more controlled environment, and can produce objects of up to 275x265x240mm in size. There are three different versions capable of printing with one, two or three simultaneous plastic colours, priced at £2,359, £2,760 and £3,440, respectively. The one shown below is the CubePro Duo.

3D Systems CubePro Duo

Offering similar capabilities is the CubeX model, with the CubeX Trio (below) costing £2,384. All of the 3D Systems models are capable of printing using either PLA or ABS plastic, with the Duo models also able to handle nylon. All are also able to support a layer thickness down to 70 micrometres.

3D Systems CubeX Trio

In contrast, the RepRapPro Ormerod (below) is supplied in kit form for £399, and is in fact described by its creator Bowyer as an open-source device – meaning that all of the components that make up the printer can be easily sourced off the shelf (such as the motors) or manufactured using another RepRap.

RepRap Pro Ormerod 3D printer

A range of sample 3D objects was also on display, to demonstrate the wide range of things that can be produced by one of these printers.

3D printed object close up

These included the robotic digger shown in the picture below, which was comprised of 3D printed parts plus motors and a controller with display.

3D printed objects

Also on show from 3D Systems was the Sense 3D scanner that enables users to capture real objects – even people's heads – and then print them out as a model.

At the event, Bowyer spoke of the wider implications of 3D printing as the technology improves and becomes more widely adopted. Overall, he expected that 3D printing would be a good thing, enabling ordinary people to become more creative and to manufacture objects for themselves that would otherwise require a factory to produce.

He was also dismissive of the notion that 3D printers would destroy industry, saying that many things will still have to be manufactured the traditional way. "We're not going to be using this to make supertankers anytime soon," he said.

While Bowyer said some business models might be threatened by the rise of 3D printing, this was just a normal part of technological progress. "When was the last time you bought a roll of photographic film?" he asked the audience. "This entire industry has disappeared, almost unremarked and unmourned."

On the question of potential copyright infringement with 3D printers, Bowyer said he "had a little bit of sympathy" for copyright holders, but compared the situation with that of the music industry and digitisation. Musicians, he said, typically aren't too bothered about copying, because they make most of their money from live performances.

"The people who have been taken out of the mix are all the people who used to live in the middle and acted as a gateway between the musicians and the public. Now that connection can be made directly," he said.

In any case, intellectual property rights did not apply to the vast majority of objects people would want to make, according to Bowyer.

"There's no patents or copyright on teaspoons or coat hooks." he said.

Google Glass eyes-on review (2014)

24 Jun 2014

Google finally launched its Glass Explorer programme in the UK on Monday, making its fabled wearable technology available to enthusiasts and developers in the region – albeit for a hefty £1,000.

Designed to help Google fix problems and develop the Glass technology before its wider global release, the Explorer Programme has been running in the US since 2012 and, according to Google, has massively improved the platform.

In fact, Google says the Explorer Programme has been such a success that the version of Glass V3 tried a year ago is archaic compared with the current version being sold in the UK. So when we were offered the chance of a fresh eyes-on look at Glass, we couldn't resist the chance to check on Google's progress.

Design and build
The basic Google Glass design hasn't been changed since we last tested it and the majority of the upgrades are software based.

This means in its basic form Glass has the same slightly futuristic-looking metallic frame with a power pack at its rear and a mini high-resolution display on its front.

While predominantly designed for use with voice commands, Glass also has the same trackpad feature on its right arm, which lets you turn it on with a tap, or navigate through the device's menus with up-and-down strokes. It also has a camera button that lets you silently take a photo or shoot a video using its 5MP 720p camera.

In the past, while we've found the bare-bones Glass version comfortable to wear, we couldn't escape the feeling that the device made us look very strange. Even if we wore them in Soho, one of London's quirkier areas, we'd still feel self-conscious.Google Glass view from the front

But Google has inked deals with a number of frame manufacturers to make Glass more friendly for public use, and to make the frames look more like regular glasses.

At the Glass UK launch event we got to see a number of different frames and were impressed by how good a job they did to make Glass look more subtle. The frames ranged from regular office specs to 1980s Terminator-style sunglasses.

While the glass technology is still very prominent, the frames go a long way to make them less noticeable, which, as well as making us feel less conspicuous, will also make them less obvious to potential thieves. Considering their hefty price tag this is a very good thing.

Operating system and software
As before, Google Glass runs using a heavily customised version of Google's Android operating system and is designed to offer users a similar experience.

Powering it up by leaning our head back, we were able to perform a variety of tasks. These included searching for a picture online, taking a photo, getting directions using Google Maps and opening various webpages simply by saying "OK Glass" followed by a command.

To get directions, for example, we said, "OK Glass, King's Cross Station", and then tapped directions on the trackpad to launch the Maps app. Once open the app presented us with a dynamic map showing our current location. Impressively we found the icon showing our location actually reacted to where we were looking, making it easy to know which direction we should walk in to get to our desired Tube stop.

Glass is also confirmed to integrate Twitter, Facebook and Google Now to offer users dynamic push updates. Though, as we found with our first hands on, we didn't get a chance to see how Google Now works on Glass, as it wasn't connected to our Google account.Google Glass front UK launch

Third-party applications
While the innate services on Glass are impressive, we were more interested in testing out the wealth of third-party applications on offer. Google has been trying to increase developer interest in Glass since it first came up with the idea. One year since we first tested the technology, we have to say we were impressed with some of the applications on show at the Glass UK launch.

While we didn't get a chance to try some of the more enterprise, healthcare and education-focused apps Google has been ranting about, we did see a wealth of interesting products, chief of which were Word Lens, Star Chart and Goal.com.

Word Lens is an innovative application designed to make Glass translate any text you're looking at. The app is currently available in a number of European languages including English, French, German, Spanish and Italian. We were impressed with how well it worked.

The app could be launched at any time simply by saying "OK Glass: translate". Once activated we simply had to look at the piece of text and tap the language we wanted it translated to using the trackpad. We found not only was Word Lens accurate, it was also very quick and was able to translate posters and information boards in seconds.

Star Chart is a free application designed to offer users information about the stars. It does this using an augmented-reality display that offers dynamic feedback and information on any constellation the user is looking at, or in the direction of. The information is displayed as text or as an audio file that's played using bone-conduction technology. This is similar to the technology used in some hearing aids and is designed to let Glass play audio without using traditional speakers or headphones, by transmitting sound through the bones of the skull to the inner ear.Google Glass launch event

The Goal.com application lets users set up custom information feeds about football. The feeds can be set to push updates about specific games, teams or leagues to the user via Glass. While the feature isn't of direct business benefit, unless you happen to be in the football industry, the app is a good example of how Glass could theoretically be used to keep up-to-date with news 24/7. For example, how useful would it be for any IT professional or business user to have a permanent feed pushing news updates and industry analysis from V3 on Glass?

Display
Google says the display offers users an equivalent viewing experience to watching a 25in high-definition screen from eight feet away. Initially we found the screen was slightly blurry and difficult to use at the busy launch event, but we soon sorted this by altering the angle we were viewing it from using the hinge connecting it to the metal frame. The screen seemed no better to us than non-HD TV quality, falling short of current high-end smartphone displays.

Battery
Poor battery has been one of the key gripes coming from the Google Glass US test group, with many complaining that it dies in hours. We didn't get a chance to test the battery life, but the spokeswoman on hand told us she generally gets about four and a half hours of use before having to reconnect it to a micro USB charger.

Overall
One year on from our first encounter with Google Glass, we have to say we're impressed. While the updates aren't groundbreaking it's clear Google is getting some momentum in increasing developers' interest in the technology. Hopefully with Glass now available in the UK this will continue and we'll see yet more innovations and app-development projects in the very near future.
