Monster 100W LED Flashlight Produces a Whopping 8500lm!

100W LED Flashlight

[Yannick] got a hold of a 100W LED diode recently, and like any self-respecting hacker, he just had to turn it into a ridiculously over powered flash light.

The tricky thing about these diodes is that they need a high amount of DC voltage, anywhere from 32-48V typically. [Yannick's] using a 12V sealed lead acid battery coupled with a 600W constant current boost converter which ups it to 32V at around 3.2A. He also managed to find a giant aluminum heat-sink to keep the diode from getting too hot. A 120mm fan helps to keep the heat sink nice and cool, which allows the light to be run constantly without fear of burning it out. But just in case he also has an Arduino monitoring the temperatures — oh and it provides PWM control to adjust the brightness of the light!

To focus the flashlight he bought a proper lens and reflector which can be mounted directly to the diode. At full power the LED puts out around 8500lm, which is brighter than almost all consumer projectors available — or even the high beams of a car!

This isn’t the first time we’ve seen a 100W LED diode being used as a flashlight, but the builds are definitely getting fancier!

What Could You Do With 7 Fingers?

7 finger robotic glove

A strange thought yes, but MIT researchers think an extra two digits could really make a difference in many people’s lives. And as it turns out, having an extra robotic grasp allows you to do quite a few things single handed.

The extra two fingers provide three degrees of freedom each, and are mounted off the user’s wrist. A series of position recording sensors attached to the glove provide feedback to the system in order to control the fingers naturally, just by using your hand normally.

They taught the algorithm that controls the fingers by trying to pick up different (large) items using the hand and manually positioning the fingers. What they discovered is almost every grasp could be demonstrated as a combination of only 2-3 grip patterns. 

The extra augmentation allows [Faye Wu], a graduate student working on the project, to peel a banana one handed, pick up large and bulky objects easily, pick up and stir a coffee with one hand, or even open a 2L pop bottle — again — with only one hand.

"This is a prototype, but we can shrink it down to one-third its size, and make it foldable," Asada says. "We could make this into a watch or a bracelet where the fingers pop up, and when the job is done, they come back into the watch. Wearable robots are a way to bring the robot closer to our daily life."

What do you think? What could you do with an extra couple digits?

EFF Launches Open Router Firmware

Open Wireless Movement logo

The Electronic Frontier Foundation have released an alpha of their own Open Wireless Router Firmware as part of the Open Wireless Movement. This project aims to make it easier to share your wireless network with others, while maintaining security and prioritization of traffic.

We’ve seen a lot of hacks based on alternative router firmware, such as this standalone web radio. The EFF have based their router firmware off of CeroWRT, one of the many open source firmware options out there. At this time, the firmware package only targets the Netgear WNDR3800.

Many routers out there have guest modes, but they are quite limited and often have serious vulnerabilities. If you’re interested in sharing your wireless network, this firmware will help out by letting you share a specified amount of bandwidth. It also aims to have a secure web interface, and secure auto-update using Tor.

The EFF has announced this “pre-alpha hacker release” as a call for hackers who want to join in the fun. Development is happening over on Github, where you’ll find all of the source and issues.

My Little Pony fans can 3D print their favorite ponies thanks to new site

My Little Pony fans can 3D print their favorite ponies thanks to new site

Been looking for a way to express your love of all things My Little Pony? You may be in luck. Hasbro just launched a new site that gives fans a way to purchase fan art created by amateur artists in the form of 3D-printed figurines.

The site is called SuperFanArt. With it, people can upload their artwork for other fans — who can then have those designs printed on demand via Shapeways, a 3D printing marketplace and community.

Now, before you start getting nervous at the prospect of the artwork being vulgar don’t worry: Hasbro will approve every single design before it’s added to options from which people can make purchases. With the potentially unseemly stuff weeded out, the site will offer an outlet for fan art from that’s totally respectable, even if the designs aren’t quite universally appealing enough to be sold at retail.

Five preapproved artists were featured on the site at launch, the majority of whom are bronies, but anyone who likes to create pony art can contact Hasbro to join up. The cool part here is the artists get to set their own prices and will share the profits with Hasbro. Traditionally, companies discourage fan art as a breach of trademark but Hasbro is instead embracing it by offering an official outlet. It’ll be interesting to see if this is picked up by other franchises with large fan bases, since this appears to be the first time a major toy company has approved 3D printing of their intellectual property.

This is just another step toward the mainstreaming of 3D printing. Earlier this month, Home Depot began stocking MakerBot, a 3D printer for at-home use.

GUEST POST

What job really needs to be done? Take 2 minutes to find out (video)

Entrepreneur and educator Steve Blank is producing a series of “2 Minute Lessons:” short videos explaining key aspects of the “lean startup” approach. In this installment, he talks about how to figure out what problems your customers really have.

Products are sold because they solve a problem or fill a need. Understanding problems and needs involves understanding customers and what makes them tick.

Smart entrepreneurs know they must get out of the building to discover every detail about their customers, especially how they experience a particular problem and why (and how much) it matters to them.

When your product solves a problem that costs customers sleep, revenue or profits, things are definitely looking up.

Use a simple "problem recognition scale" for each important type of customer:

  • a latent problem: they have a problem but don't know it
  • a passive problem: they know of the problem but aren't motivated or aware of the opportunity to change
  • an active (or urgent) problem: they recognize a problem or passion and are searching for a solution but haven't done any serious work to solve the problem
  • a vision: they have an idea for solving the problem and even have cobbled together a home-grown solution, but are prepared to pay for a better one

If they fall into the last two categories all you need to do is convince them that if they built it themselves, they're detouring into a different, usually non-core business — your new business!

Osteopathic physicians tell patients: Beware of health apps!

Osteopathic physicians tell patients: Beware of health apps!

At its annual shindig in Chicago, physicians in the American Osteopathic Association over the weekend agreed to warn patients that health apps and websites are no substitute for a visit to the doctor.

The AOA adopted a resolution that the osteopaths will "actively educate patients on the importance of seeing a physician when ill or injured and in need of a medical diagnosis, and that patients not allow recommendations from these medical websites or applications to be used as a basis for delaying, or as a substitute for, evaluation and treatment by a physician."

Osteopathy is an alternative medical treatment involving massaging, moving, and stretching joints and muscles. Osteopathic physicians (D.O.s) are trained much like medical doctors (M.D.s) but also use osteopathic treatments.

The resolution was based on the belief that patients are increasingly turning to the web for medical information, and sometimes for advice. The AOA cites a September 2013 survey from Makovsky Health and Kelton saying that the average American spends about 52 hours each year on the Internet looking up health information.

The group called out the “symptom checker” functions at WebMD, the Isabel Symptom Checker, and EverydayHealth as being potentially dangerous if used as a sole source of medical information.

“The AOA policy recognizes that every patient is unique and may present symptoms in a different manner, which makes it necessary to schedule an in-person appointment with a physician or consult by phone, email or telemedicine,” the group said in a statement Monday.

“Additionally, medical websites and apps do not usually take into account patient medical history and have limited ability to search for possible drug interactions.”

"Physicians want to see patients educating themselves and taking control of their health and when used correctly these medical websites and apps are a great tool," says Michael Brown, an osteopath, in the statement.

"However, the AOA wants to make sure patients realize that these sites and apps, no matter how convenient, cannot replace the patient-physician relationship," Brown adds.

The AOA represents more than 100,000 osteopathic physicians and medical students in the U.S.

Russia reopening spy station in Cuba, but it’s a PR stunt, not a new threat

Russian spies will soon arrive in Cuba to begin intercepting U.S. communications.

The impoverished, communist Cuban government, with Raul Castro calling the shots, signed a deal with the Russian’s to re-open Lourdes, a massive Cold War signals intelligence (SIGINT) base used by Russia to vacuum up U.S. ultra high frequency (UHF) radio communications. Russia opened the base in the 1970′s and later closed it due to financial costs.

Now it’s opening the base again, for the first time since the Cold War ended.

The deal was inked last week between Russian president Vladimir Putin and Raul Castro. Cuba is one of the few countries these days welcoming Putin with open arms. The Russian president is facing international outrage after pro-Russian guerrillas in the Crimea shot down a Malaysian Airlines 777 with a sophisticated surface-to-air missile last week.

Technology has evolved a good deal since the 1970s, when UHF radio was (nearly) state of the art. So, the good news?

“It’s a political, Cold War move more than anything,” a former National Security Agency official told VentureBeat.

“The Russians don’t need to draw attention to themselves by opening a SIGINT listening post. If they were serious about intercepting communications from inside the U.S. they wouldn’t be talking publicly about it.”

In other words, the announcement is a political jab, not a real intelligence threat. Your Gmails are no more in danger than they were before.

“Public relations is the end goal here. So you can bet the Russians are not doing anything significant there with regards to comm intercepts,” the former official said.

Lourdes is about 100 miles from the U.S. and was considered the largest Soviet-era listening post outside the then Soviet Union. At its peak in the 1970′s, more than 3,000 Russian technicians manned the controls, mainly intercepting and analyzing communications within the U.S., like phone calls and radio comms.

For their part, the Cubans liked to brag that Lourdes provided Russia with 75 percent of its “actionable” intelligence on the U.S. Many intelligence experts said that number was highly exaggerated.

These days, a large part of SIGINT collection is done by computer networks and teams, hidden in nondescript buildings and covert listening posts all over the world. Technicians engaged in that sort of work don’t want their covers and methods blown — and they don’t need to move to troubled Caribbean nations to do it.

Russian SIGINT personnel are highly competent, but its unclear if those soon to be living and working at Lourdes will work to steal American secrets, like cell phone traffic, for example.

“Lourdes was a traditional high-frequency listening post, and its proximity made it dangerous,” the former NSA official said. “Now it’s computer to computer, and not the location itself.”

“At a technical level, the Russians are just as good as we are. Although they don’t have the consistency we do, their intelligence value is high. They’re good,” the official said.

The Cold War is back. And heating up. But the real action is probably not actually in Cuba.








Rainforest-monitoring project hits Kickstarter goal early, ups the ante with tribal deals

Rainforest-monitoring project hits Kickstarter goal early, ups the ante with tribal deals

When VentureBeat broke the Rainforest Connection story just three weeks ago, the startup was seeking $100,000 in Kickstarter funding to help detect, report, and halt chain saw activity in the world’s fast-shrinking supply of rainforest — by using recycled smartphones as chain saw detectors.

Blowing through the $100,000 goal in less than three weeks, the tiny company is nearly doubling the request to $195,000 on Kickstarter. The added funds will enable an increased number of pilot projects.

In addition, the publicity has helped the company form two new partnerships with tribal groups in impacted regions:

These partnerships are intended to help protect native lands that are under destructive threat from “massive black market illegal logging operations.” Loss of rainforest is considered the second leading cause of global warming, according to the original report.

Rainforest Connection’s technology marries surplus Android smartphones with a novel solar array that powers the phones 24/7 under the rainforest canopy. Special software monitors the smartphone’s microphones. If the phones pick up the distinctive sound of chainsaws — from as far away as a kilometer, or about half a mile – the software calls a pre-determined number to summon help. White both invented the solar array and developed the software.

Topher White, the founder and creative force behind Rainforest Connection’s smartphone plus shade-capable solar array technology, credits Kickstarter success to strong media coverage and video help from celebrity activists like musician Neil Young.

Speaking for the Tembé In Brazil, Vasco M. van Roosmalen of ECAM said, “The technology being developed by Rainforest Connection is an extremely powerful tool for the protection of rainforests, especially in our case — when combined with the on-the-ground presence and determination of local indigenous groups serving as guardians of their traditional lands which occupy over a quarter of the entire Amazon region."

With a population of a mere 1,500, the Tembé recently won a large victory that gives them title to over 600,000 hectares of rainforest. Protecting the area has been a challenge. The Tembé report massive illegal logging operations on these lands, five to 10 trucks at a time on narrow dirt roads, hauling timber illegally out of the Amazon rainforest.

The Panama pilot program in the Mamoni Valley Preserve, in partnership with the Guna indigenous population and Smithsonian-supported nonprofit Earth Train, is up for consideration. RFCx is proposing a plan to protect thousands of acres of rainforest, starting with a pilot that initially covers up to 5,000 hectares. The pilot will test device connectivity, monitor access points and explore potential coordination with other technology applications.

"The Mamoní Valley Preserve buffers an especially vulnerable part of the 250,000-acre Narganá Wild Area", said Enrique Arias, former Secretary General, Guna General Congress and Director of Earth Train's Leadership and Guide Program.

As the original Kickstarter campaign enters its fourth and final week, RFCx funding expansion is offering $40 carbon certificates to the public to protect endangered rainforests and protect enough carbon to  "take your car off the road."
