Sheet metal-framed Voiroo Zero mountain bike brings rivets to riding

The Voiroo Zero's aeronautically-inspired frame
Italy's Albaviation is in the business of manufacturing small aircraft, along with parts for them. So, what happens when the company's TrixonLab division decides to build a hardtail mountain bike? Well, with its riveted sheet aluminum construction, the Zero's frame is pretty reminiscent of a retro airplane. According to its creators, however, there's more to the design than just unique looks.

The Zero is the first model in TrixonLab's planned Voiroo Bike line. Other models in development include road and urban bikes.
Using a CNC (computer numerical control) system, the main components of the frame are first cut from sheets of 0.6 to 0.8-mm aluminum – some smaller bits are made from thicker sheets. The resulting flat pieces of metal are subsequently folded and molded into the desired shapes, then riveted and glued into place.
The company's Giorgio Mannozzi told us that this design, commonly used in the aeronautical field, offers a good weight-to-rigidity ratio. "The box structure allows us to have a monocoque, a single structure without specific weaknesses," he said. "On an equal weight (tube structure vs. box structure), the box structure allows us to have a greater rigidity and especially robustness."
Additionally, there are no welds in the frame, which are a structurally weak point on traditional tube-based bikes.

TrixonLab plans to build the Zero to order, and will offer it as a frame only, or in one of two complete bike builds. The frame weighs 1.65 kg (3.6 lb), and will sell for €460 (about US$590) on its own. A full bike featuring a Shimano XT groupset, Rock Shox Recon Gold TK suspension fork and XT 27.5-inch wheels will go for €2,490 ($3,194), while a bike equipped with Shimano Deore, Rock Shox XC 30 TK fork and Mavic Crossride 27.5-inch wheels will set buyers back €1,690 ($2,168).
California-based Ronin Bicycle Works also makes bikes from sheet aluminum, although it recently didn't meet the funding goal in a Kickstarter campaign aimed at taking them into large-scale production.
Sony’s SmartEyeglass is a head-turning Google Glass alternative

Sony's SmartEyeglass is somewhat clunky-looking Google Glass competitor
While Sony’s smartphone division hasn't exactly been on the up-and-up, the company still isn't afraid to try its luck down new roads. Sony today announced its own heads-up-display-packing wearable, known as SmartEyeglass. The headset, which is designed to pair with Android smartphones, offers a built-in camera and several sensors.
Much like Google Now-powered Android Wear smartwatches, Sony’s new head-mounted wearable is designed to provide the user with context-aware information, right when they need it. The device makes use of a CMOS image sensor, coupled with an accelerometer, gyroscope, electronic compass, brightness sensor and a microphone.
As you might expect from a head-mounted wearable, there’s also a camera on board (3 megapixels). SmartEyeglass is technically compatible with smartphones and tablets running Android 4.1+, but you’ll need to be running the more recent 4.3 release onwards to make full use of the wearable’s camera.

Sony has used “unique hologram optics technology” for the device’s lenses, which offer a transparency of 85% and are just 3 mm (0.12 in) thick. The projected display is monochrome and reportedly easily readable in a variety of environments. The headset will draw GPS data from the tethered smartphone or tablet, with that device running the apps and pushing data to the wearable.
SmartEyeglass is clearly designed to compete directly with Google’s much publicized Glass wearable. But while the Mountain View-based firm has spent years encouraging development of practical applications for its headset (the Explorer Edition release of the product is currently available for early adopters), Sony’s platform is much earlier on in the development process.
It’s likely that SmartEyeglass developers will be able to feed off some of the creativity we’ve seen in Glass applications (such as its use as an aide for Parkinson’s sufferers), but it’s likely to be some time before the level of functionality catches up.
The wearable is currently a development prototype, and even includes an external controlle...
To get the ball rolling, Sony has today released the SmartEyeglass Software Development Kit (SDK) for developers, while highlighting some potential uses for the tech, including the ability to provide heads-up walking directions or player stats while watching live sports.
The second big obstacle that the wearable will have to overcome is its clunky looks. Wearers of Google’s Glass headset turn more than a few heads walking down the street, and it looks pretty tame by comparison.
That said, the version currently on show is a development prototype, and even includes an external controller that houses the device’s battery and microphone. It’s likely that the final release will be far more streamlined ... or at least we'd hope.
Sony hasn’t announced a roadmap for a consumer release for SmartEyeglass, but plans to make it available for sale to developers by the end of the year.
