CitiBike Smart Helmet Leads You to the Nearest Bike Docking Station

Bicycle riders in New York now have a new weapon in the commuting wars. The CitiBike Smart Helmet will show you the way to the nearest CitiBike docking station. That’s pretty handy. Maybe I should say heady. It is a helmet after all.

The Carrera foldable helmet used for this project is embedded with LED strip lights, a FLORA accelerometer, a compass and a FLORA GPS system. All of this is used to guide the rider to the nearest bike docking station in the city, using blinking lights in the periphery of the rider’s vision to show them the way. The colorful LEDs on top serve no purpose other than to provide a cool light show, though.

That should save people a lot of time and effort. This project comes from Tyler and Justin Cooper, who have provided all the instructions to make your own CitiBike Smart Helmet if you are inclined. Pretty neat.

Modular Aerial Vehicle: United We Fly

We’ve seen how robotic quadcopters can be programmed to act and complete tasks together. These single propeller vehicles called Distributed Flight Array take that concept to the extreme. On its own, a single one of its aircrafts can barely take off and its flight is unstable. But when multiple modules connect, they become stable, can retain their formation on their own and even resist external forces.

The Distributed Flight Array was conceived by Raffaello D’Andrea and Raymong Oung of the Swiss Federal Institute of Technology’s Institute for Dynamic Systems and Control. Each vehicle has its own power source, motor, computer and sensors. They also have tiny wheels that let them scurry on the ground. They attach to each other using magnets, which are apparently stable enough to keep them together in normal flight.

Will these drones replace the collegiate bands that play at football halftime shows? Will they lead to the creation of super robots? Will they lead to the creation of real-life platforming games? Only time will tell.

iPhone Carbon Monoxide Detector Case Concept Could Save Lives

Carbon monoxide is a colorless, odorless, and tasteless gas. Inhaling enough of the gas can poison you and possibly kill you, but because of its nature, you’ll have no idea when or if you’re being exposed to it. The presence of the gas can be identified using carbon monoxide detectors, though.

People don’t really have carbon monoxide detectors installed in their homes or in their cars. So David Tyer decided that the best way to go is to design an iPhone case with a built-in carbon monoxide detector in it.

His design makes sense. For one, people carry their phones with them wherever they go, so if they’re being exposed, then their phones could alert them of the risk.

The only downside is probably the fact that having a built-in carbon monoxide detector might make the case bulkier and burn through more battery than most users would like. Most detectors are a little on the bulky side, so I’d expect a small and compact detector to cost a bit more than usual.

Tyer’s design is only a concept for now, but who knows? Some manufacturer out there might just decide to make it.

Camera System Keeps Track of Fast Moving Objects: Flash Focus

A camera that can keep a fast moving object in its sight is very useful. It could be adapted to cover sports or wartime events, or for academic and military purposes. That’s why a group of researchers at the University of Tokyo’s Ishikawa Oku Laboratory are working on a camera system that can automatically keep its eyes on the prize.

The current prototype uses two small mirrors that move independently of each other: one for panning and one for tilting. DigInfo says that the mirrors are controlled “in the order of milliseconds” and the camera can take an image every 1/1000th of a second. Even more impressive, the system can also be used in reverse. Instead of taking an image, it can project an image onto a fast moving object in real time. Imagine being able to tag an escaping prisoner or a wild animal. Or a celebrity.

I wonder if it could track a bullet.

PIP Biosensor Turns Relaxation into a Game

Relax. Take it easy.

For some people, those words are easier said than done. I mean, how hard can it be to relax and just bum around? Apparently, it’s hard if you’re stressed out at work or have to broker deals that just aren’t coming together.

That’s what PIP is for. It’s a biosensor and app system that encourages you to relax by turning it into a video game.

pip biofeedback device

The PIP biosensor is supposed to be held between the player’s thumb and forefinger. It communicates to your iOS or Android device via Bluetooth to work with the games that it comes with. PIP works by measuring the user’s galvanic skin response, which is a natural reaction to stress.

The games encourage you to reduce this stress and relax through app’s gameplay.

PIP biosensor1

For example, “Relax & Race” will have the player control a flying dragon through a race course. The more relaxed the user is, the faster the dragon flies. If the player is all tense and wound up, then the dragon will fly slower. Its makers plan on offering three games when the system first comes out.

The PIP biosensor system is currently up for funding on Kickstarter, where a minimum pledge of $99(USD) will get you one of your very own, plus a game of your choice.

Robot Dancing Gets an Upgrade

A new robot designed by the Korean Advanced Institute of Science and Technology has taken robot dancing out of the jerking movements of the 1980’s and made them modern. A pair of robots that are good enough to copy the dance moves of humans has been ordered by the folks over at Google.

Vizio M-Series Razor LED TV Review

I recently had the opportunity to go hands-on (and eyes-on) with one of Vizio’s new M-Series Razor HDTVs and I have to say that I’m really impressed with all of the bells-and-whistles you get for such an economical display.

vizio m 32 1

For this review, I tested the smallest model, the 32-inch version, but the M-Series is available in sizes all the way up to 80 inches. The display I tested offers true 1080p resolution, along with edge LED backlighting and local dimming. This combination allows for a reasonably thin display while offering really good contrast and black levels. Overall, the 32-inch model measures under 2″ thick when hung on the wall, or about 7.5″ thick on its stand.

vizio m 32 3

As a firm believer in the black levels on plasma displays, I was pleasantly surprised by the inky blacks and lack of blooming on the Vizio display. I guess LED/LCD screens have come a long way in the last few years. I did find the colors to be a bit too oversaturated for my liking in the “Standard” display mode, so I switched to “Calibrated” and that fixed things right up. I also turned on the setting that recovers detail in black areas at its lowest level. Other than that, I didn’t touch the factory settings.

The 32″ model I tested has a 120Hz refresh rate, which seemed to be fine for any motion scenes I threw at it, though the 50″ and larger models offer 240Hz refresh rates if that’s something you must have. My 32″ set offered three HDMI inputs and one USB port, while the 50″ and larger models add one more HDMI port and another USB port. All M-Series set offers built-in 802.11n Wi-Fi for fast and easy internet connectivity, and my experience was that getting connected to my home network was a snap. Those larger models also include passive 3D, which I didn’t get a chance to test since the 32″ model doesn’t support that feature.

Setting up the display is stupid simple, with a nice guided user interface which walks you through every step of getting your inputs and internet connection set up.

Built-in audio quality is decent, and the display does offer simulated surround sound. However, I’m a bit of an audio snob, so I’m never one to use the sound system built into a display. That said, if you’re getting one of the smaller models, sound is good enough to fill a small room without noticeable distortion, and you can truly enjoy all of your media with just a single device should you choose to go down that path.

vizio m netflix

While the picture quality is quite good on the M-Series display, the thing that I really like about the set is its integrated “smart TV” app suite. With a press of a button (or two) you have access to Netflix, YouTube, Amazon, Hulu Plus, Vudu, Rhapsody, Facebook, Twitter and several other services. I also was able to download and install Pandora from the Yahoo! connected app store. I only wish they had HBO Go, and then my life would be complete. All of these are integrated using Yahoo! widget technology, other than Netflix which appears to be directly integrated into the display.

vizio m remote

Netflix even has a dedicated button on the remote, which immediately launches their app. There’s also a button for Amazon (but that launches the Yahoo! widgets), and another dedicated button for a new service called M-Go, which has yet to be released on the set. While the Yahoo! widgets are starting to feel a bit dated (I’ve had them on one of my Samsung displays for several years now), at least Vizio has solved the speed problem found with earlier versions, and these load up almost about as fast as you can push buttons on your remote.

Setting up each of your online accounts can take a few minutes because you have to use the on-screen keyboard to enter your credentials. For an internet-connected TV, I wish they had included a keyboard like they had on some of their previous remotes. This is a minor inconvenience, unless you find yourself frequently searching for content instead of browsing through the menus in the various connected apps.

I especially like the UI on the YouTube app, which is the nicest I’ve seen yet, with easy access to each of YouTube’s major categories in a HDTV-optimized experience.

In addition to streaming online content, the set can access media stored on either USB devices or on DLNA-compatible devices, so you can stream media from your computer easily.

vizio m amazon

What I really like about the integrated apps is the ability to seamlessly switch between traditional satellite/cable programming and streamed content. Plus, the remote even supports fast forward/rewind and pause controls for all streamed content sources, providing a truly integrated experience with no additional hardware.

Overall, I found that the M-Series offered a good mix of display quality and a rich suite of connected apps for – especially for the price. The built-in wireless connectivity means you can just plug in the displays and go – with no additional hardware. In theory, you could get away without cable or satellite service if you wanted – though you still need a high-speed internet connection to enjoy streamed content on the display.

The 32″ M-Series Razor display sells for just $399.99(USD), with prices for the rest of the line ranging from $529.99 to $3999.99. You can find more information about or purchase the M-Series displays over on the Vizio website.
