LED Handlebars Illuminate Bike Safety

353660_d_VexrpCx5kxRYdY4l0teOFs4

When it comes to bike safety, there is no shortage of illuminating reflectors, clamp lights and frame lights to make night riding less of a dark peddle down the road of hazard.

Yet the newest addition to hop on that saddle entirely does away with the need for fastening anything to your bike. Instead, Mitchell Silva has created GLOBARS and they perform just like they sound. They're handlebars integrated with LED lights.

BLOG: Black-light Bubbles Will Blow Your Mind

"My idea was to create a bicycle light that could be easily used, and offer the same user friendliness of integrated bicycle lights, while remaining at a significantly lower price point," Silva wrote on his website.

For his prototype, Silva cut long strips out of the bars and installed plastic tubing on the inside to keep them rigid.

"I then installed approximately 40 high-efficiency LED bulbs into the inner plastic tubing, and installed a momentary actuator button on the back of the bars," Silva explained. "The whole system runs off a watch battery."

Silva envisions his GLOBARS benefiting those who face the most danger: urban cyclists. In 2009, 630 cyclists were killed in the United States alone and 51,000 were injured. Of those accidents, 70 percent occurred in urban areas.

Besides their safety attributes, GLOBARS are super bright and, not to mention, really cool-looking. And who wouldn't want to ride around the city streets at night gripping a pair of glowing-bull-horn handlebars?

Bendable E-Reader Going into Production

Lgdisplay

E-readers are a great tool, but the one big disadvantage is that they're made of breakable glass and sensitive electronics that can get damaged when dropped. Books, by contrast, are pretty durable.

LG Display has brought flexible, light and tough e-readers a little closer to reality. The company announced that it is mass-producing a flexible electronic paper display, or EPD.

It's called the XGA, and is 6" across, smaller than most tablets and bigger than a phone. LG says the e-reader can handle getting bent up to 40 degrees and is only 0.7 millimeters thick -- about the same as six sheets of typical office paper and slimmer than typical displays. It also weighs less than half an ounce. It has a resolution of 1024 x 768 pixels, which is as good as any current e-reader. 

As for toughness, LG says the display can handle getting dropped 1.5 meters, or a hair under five feet. That's about where most people would hold an e-reader standing up.

NEWS: E-Reader Lets You Physically Turn the Page

This isn't the first flexible display -- AU Optronics unveiled one in November -- but this is the first that has gone into real production. LG says the breakthrough was in manufacturing. Instead of building the back of the display with breakable glass, they built it with plastic, which is why it can bend. The press release isn't clear on exactly how LG got the e-ink display to work on a plastic substrate, but they did. 

It won't be in any real e-readers for a while yet -- the first releases are going to Chinese companies, and to European manufacturers next month.

Payment Just A 'Bump' Away

Bump

BumpPay: Free

That awkward moment when you remember a friend owes you money could be a little less weird, if all you have to do is bump phones to settle your debt. That’s the idea of Bump Pay, an app that uses an algorithm to run cloud services that receive PayPal information from a phone through a “bump.” The signal from that bump listens to others bouncing around the world and pairs up with their friend’s phone to route payment info.

BLOG: How to Survive an Internet Blackout

The app sends your PayPal email to your friend, or vice versa, making those transactions quicker and just as secure as using PayPal directly. This kind of transaction works best for those splitting lunch or settling a small bet because it can only send amounts up to $1,000. However, roomies who split rent might benefit from some “bumping” as well.

Lamprey Micro-Robot Could Detect Disease

Lamprey_mouth

To locate disease in the human body, it would be great if a doctor could get inside and look around. Imaging technology helps, but the resolution of the image isn't always good enough for analysis. On top of that shortcoming, a lot of imaging technologies, like MRIs, involve using large, expensive machines the size of a small room.

That's where something called cyberplasm comes in. To learn more about this micro-robot, which fuses together microelectronics and biomimicry, Daniel Frankel of Newcastle University is leading a U.K.-based study with the support of a research team from the National Science Foundation in the United States.

BLOG: Flying Robot Swarm Performs James Bond Theme

The idea is to have an electronic nervous system (which every robot ultimately has) with sight and smell sensors derived from animal cells. Cyberplasm's artificial muscles would be powered by glucose, just as real muscles are. In addition, the robot would respond to light and chemical stimuli the same way a real creature does.

To start, researchers are looking to model Cyberplasm off the sea lamprey, a jawless fish with a very simple nervous system, which makes it easier to simulate with electronics. The prototypes will be about a half inch long, with later versions being smaller –- even down to the nanometer scale.

Cyberplasm’s sensors will respond to stimuli and convert them into electronic signals, similar to how a real brain works.  The electronic ‘brain’ will then tell the artificial muscles how to move so the robot can swim.

A micro-robot sensitive to its environment and capable of swimming around inside the body could check for tumors or blood clots, for instance, or find chemical signatures of a range of diseases. That data could be recorded and used to figure out what's wrong with a patient. Aside from creating a new way to diagnose disease, the project could offer insights into building artificial muscles that work in response to electrical signals.

Kindle Fire Gets Its Own Speaker Dock

FiredockFireDock: $129.99 (Available July 2012)

The accessories pool for anything that’s not Apple-related is shallow. It’s no surprise, Apple devices are a safe bet for a good profit. However, Grace Digital seems to be banking on Amazon because they've designed the FireDock, one of the first docking speakers designed specifically for the Kindle Fire, which was released in 2011.

BLOG: Amazon's Kindle Fire: The Paperback Of Tablets

The dock has 3-inch, full-range stereo speakers and a 16-watt Class D digital amp, giving the tablet’s sound a nice boost for Pandora, gaming or audiobooks. When docked, the Kindle Fire sits on a rotatable cradle with a built-in USB port, allowing the tablet to charge while playing. It’s powered with AC power, but a separate lithium-ion battery pack can be purchased for cordless playback -- although the pack will not charge the Kindle.

Transformers Theme Park Gives Warm Fuzzies

Mr-Iron-Robot-5

If you're sick of sitting through Michael Bay's CGI schlock fests and, like me, demand a little more reality out of your Autobots and Decepticons, then you might want to consider taking a trip to east China's Zhejiang Province.

Once your plane touches down, hail a cab to the city of Jiaxing. There you'll find Mr. Iron Robot, a Transformers-themed amusement park on 556 acres of what used to be an abandoned factory. The park, which features 600 Transformer-esque sculptures made from salvaged vehicles and machine tools, is the brainchild of 49-year old Zhu Kefeng.

BLOG: Robotic Cheetah Breaks Land Speed Record

The park features old favorites likes Optimus Prime, Bumble Bee and Megatron, as well as dragons and cartoon figures. Just to dwarf your shrimpy human form, some of the sculptures are over ten feet tall. 

The park "has been very popular with the kids," Zhu told Xinhuanet. "I feel very glad when the children visit my park and enjoy the happiness here. I still remember the joy when I played with "iron toys in my childhood…" Joy shared with others, he said, is "more enjoyed."

If that last line isn't enough to convince you of Zhu's lotus-like aura, then get a load of this photo. But don't let his satorial demeanor fool you. Zhu is certainly down for letting sparks fly to build wicked tough sculptures like this one.

PHOTOS: Better Than 'Transformers': Real-Life Robots

Zhu began building his theme park in 2010 with money used from selling commissioned sculptures on the side. Him and his team spent ten years making the theme park's sculptures after distributing large recycling bins to collect iron and steel scraps.

Mr. Iron Robot was officially granted status as a tourist attraction on March 20, making it China's first theme park to feature artworks made of recycled iron and steel.

If anyone is interested in carpooling to Jiaxing, give me a holler. Trust me, you're going to welcome my monetary pitch-ins. It's a long drive and keeping the tank full of gas is going to be brutally expensive.

Robotic Sand Flea Jumps 30 Feet

Sand flea

Robot designs have been inspired by cheetahs (for speed), dogs (to carry things) and even humans. Boston Dynamics, which gave us all three, has now turned to the lowly flea for inspiration, making a robot that can jump 30 feet into the air and land safely.

PHOTOS: Top 10 Robot Jobs

It's called the Sand Flea. Real fleas jump using the strength of their feet, and can go hundreds of times the distance of their own body length. The robotic version uses compressed gas and can't go quite so high, but jumping to the roof of a two-story building is still pretty impressive. It has four large wheels so it can tackle rough terrain. Boston Dynamics says the robot uses a stabilization system to keep itself righted when it flies through the air.

The Sand Flea carries a camera to give a controller up to 215 yards away a view of the surroundings. And it can even swim. The robot is small, about 11 pounds, and has enough compressed gas for up to 25 jumps.

The Sand Flea -- along with the throwable Scout XT robot -- is headed to Afghanistan, where it will be tested in real-world conditions.

Afghanistan is becoming a hotbed of robotic soldiering, as thousands have already been deployed there. The numbers are even higher when one considers the unmanned aerial vehicles used. Land-bound robots do things like bomb disposal and reconnaissance, reducing the risk to the troops in the field.

DIY Furniture Delivered in Bytes Not Boxes

Fab_Furniture

Do-it-yourself stores like Ikea are wildly popular among assemble-it-yourselfers. But now instead of supplying boxes containing planks of wood and funny-looking screws, one design firm is offering DIYers a greener way to get their furniture: open-source digital files. The project, called AtFAB, comes from the Lexington, Ky.-based design firm Filson and Rohrbacher. Hat tip to Christopher Mims, who described the AtFAB plans in a recent Grist post.

Photos: Extraordinary Beauty of the NanoArt World

I'm no fabricator (yet!), but here's my understanding of how this works: First, find a piece of furniture you like online from AtFAB's modern, prefab furniture series. Next, following the instructions on their website, request the digital "cut file" directly from the designers. Their Creative Commons licensed design file will start downloading to your computer.

A cut file contains all the information needed to make your own version of the furniture by cutting it yourself on a CNC milling machine, short for computer numerical control. CNC machines work sort of like printers, in that a computer delivers a command and the machine responds. In this case, the machines cut instead of print materials to exact 3-D specifications.

Or, if you don't have your own CNC machine, a local fabricator should be able to make the pieces from the files. Googling revealed a fabricator near me that could probably help, but the designers also suggest looking on 100kGarages.com and at DIY workspaces like TechShop.

10 Double Duty iPhone Cases

Filson and Rohrbacher's furniture pieces are intended to be cut easily from whatever material you want, whether that's metal or wood, or something wackier. Instead of wondering where your furniture actually came from, and how the people who produced it were treated, you could recycle wood into a cabinet.

Maybe one day CNC files will go mainstream and we'll be able to download whatever furniture we want and have a range of local machinists to pick from. An open-minded international retailer should get on that.

Finger Camera Frames Your Photos

15

I confess. I'm a terrible photographer -- mainly because I can never bridge the gap between getting out my camera and feeling like I'm infringing on the moment. Don't get me wrong, I've got a good eye. Often I've used my fingers to frame a memorable shot or snap an imaginary picture. But alas, no lasting images, only fleeting memories.

BLOG: Are These Satellite Images Exposing America's Secrets?

Which is why this finger camera seems like it was designed especially for handicapped shutterbugs like myself who are crippled by the ephemerality of life.

Thankfully, a Japanese research group has developed the Ubi-Camera which lets users compose a photo by looking through their fingers. Now instead of imitating your favorite film director scouting film locations, your fingers can actually put forth a finished product.

Once the match-box-sized camera is stuck on your finger, the built-in infrared range sensor calculates how far your finger frame is away from your head. That data is used to crop the image so it matches what you're seeing through your fingers.

BLOG: Future Eye-Tracking Systems Will Read Your Mind

Unfortunately, the Ubi-Camera only exists as a prototype. Plus, it has a few glitches to work out -- namely that it's connected via a cord to a computer. For someone like me who's looking to capture the moment, while still existing in it, the only use I have for a tether is when I snip it with my scissors.

On top of that, the camera has no zoom and the infrared sensor is prone to mistakes. Researchers say they're hoping to integrate face recognition into the system which could help alleviate some of the glitches.

Until then, I'll keep treading water, snapping fake photos and "Riding for the Feeling." Like Bill says, it's "the fastest way to reach the shore."

Google Now Comes With Monthly Statement

Google-bill-622

Wednesday morning, Google announced that users with a Google Account could sign up to get a monthly "Activity Report" itemizing their use of some of the Web giant's services. Opting into this takes all of one click after you sign into your account; an email inviting me to check out my first report, covering from Feb. 27 through March 25, arrived maybe half an hour later.

The results, as you can see below, were alternately fascinating and boring.

Google Account Activity report

Google's record of the locations, Internet providers, operating systems and browsers from which I'd logged into my account could have been a breadcrumb trail across the United States -- except for the lack of a corresponding map. But because I use my primary Gmail account mainly for online shopping, these stats offered minimal insight about my overall email habits.

And because Google's tracking of my Web-search history stopped on April 22, 2005 -- I don't remember why I decided to pause it on that day -- that part of my report had nothing at all. The same went for Google's Latitude location-sharing service, which I don't ever remember using.

BLOG: First Human Infected With a Computer Virus

I could see that my long-dormant YouTube account had netted a few dozen views. But the nondormant Picasa photo-sharing account that's been steadily collecting pictures via Google+ automatic photo uploading didn't even earn a listing.

At a Google Apps account I use for my work email, my Activity Report testified that I had sent 300 emails that month (unsurprisingly, the top two recipients edit my articles) and received 1,773. The busiest day was Thursday, March 15, when 166 messages landed in my inbox. But no other useful or merely salacious details surfaced on that page; it seems I had avoided doing any Web searches while signed into that account.

Google Account Activity logoIt was reassuring to see so many blank spots in Google's view of me, especially after the controversy over its recent consolidation of privacy policies.

But this monthly statement isn't a complete accounting. Beyond sign-in details, Gmail, Web history, YouTube, Picasa and Latitude, a Google representative said the report only factors in security-settings changes. (If you see any you didn't make yourself, change your password immediately). The company plans to add unspecified services in the coming months.

I suspect that adding Google Maps queries, which often pinpoint your home and maybe also your shopping habits, would change that picture the most. Google Docs usage and the volume of synced calendar and contacts entries might also provide a few eye-opening moments. To see all of those relationships, you need to inspect your Google Dashboard, which offers less detail about recent usage but lists every sort of authorized access.

ANALYSIS: World's Self-healing iPhone Case

This will be a feature worth watching. On one level, Google's Activity Reports should appeal to digital narcissists everywhere: Alongside data like Foursquare check-in histories, blogging page-view stats, and other personal metrics you can gather with tools such as the new ThinkUp web service, they constitute yet another way your online identity can keep score.

But by quantifying just what Google has seen you do in the past month -- a statistical perspective not as easy to find at Facebook, even after its recent redesigns -- these statements may also help Google users decide if they shouldn't cover up a little more when they log on.
