Listnr Wants to be 'Your Listening Assistant' (Video) 45

Posted by Roblimo
from the can-you-hear-me-now? dept.
This Listnr is "a new listening device connected to the cloud" being developed by a team in Japan that's currently running a Kickstarter project looking for $50,000 by March 7. The other Listnr "is a free music service helping people discover the best music from independent artists on Soundcloud and Bandcamp." More accurately, that's what it was, since their last Facebook post was in 2011 and their domain name is now for sale. Today's Listnr -- the listening device one -- claims it is able to tell whether a baby it hears is laughing, crying, gurgling or trying to talk. It is supposed to respond to finger snaps, hand claps, and other audio commands. It has an open API so that you can extend its use however you like. The company, too, is working on new applications for their product. Will there be enough of them, and will they interest enough people, to make this a success? Co-Founder Rie Ehara says, "We wanted to build something using sound to enrich and delight our lives." As of today (Feb. 2), Listnr is slightly less than halfway to its Kickstarter goal, so it's still a coin-toss whether or not Listnr will succeed.

VP Anthony Moschella Shows Off Makerbot's Latest Printers and Materials (Video) 47

Posted by timothy
from the now-you-can-make-fake-wood-designer-shapes-on-the-3d-printer-at-your-local-makerspace dept.
You may have read a few weeks ago about the new materials that MakerBot has introduced for its 3-D printers; earlier this month, I got a chance to see some of them in person, and have them explained by MakerBot VP of Product Anthony Moschella in a cramped demo closet — please excuse the lighting — at the company's booth at CES. Moschella had some things to say about materials, timelines, and what MakerBot is doing to try to salvage its open-source cred, despite being a very willing part of a corporate conspiracy to sell boxes of Martha Stewart-branded extruder filament — as well as a few unremarkable things that the company's ever-vigilant PR overseer decreed Moschella couldn't answer on the record for reasons like agreements between MakerBot parent Stratasys and their suppliers. The good news for owners of recent MakerBot models: they'll be upgradeable to use the new and interesting materials with a part swap, rather than a whole-machine swap (it takes a "smart extruder" rather than the current, dumber one). And the pretty good news for fans of open source, besides that the current generation of MakerBots are all Linux-based computers themselves, is that MakerBot's open API provides a broad path for 3-D makers to interact with the printers. (The bad news is that there's no move afoot to return the machines' guts to open source hardware, like the early generations of MakerBots, but STL files at least don't care whether you ship them to an FSF-approved printer to be made manifest.)

Jim Blasko Explains 'Unbreakable Coin' (Video 2 of 2) 39

Posted by timothy
from the is-it-cryptocurrency-or-cryptic-currency? dept.
Today, the conclusion of my talk with Jim Blasko (here's part 1), who encourages you to go start your own crypto currency, because it's a fun exercise and because every entrant adds new ideas to the mix. As you'd expect, he's bullish about both his own Unbreakable Coin and cryptocurrencies more generally; how any given given currency performs, though, is an open question: U.S. dollars, Euros, or Yen may not go experience any meteoric rises, but their stability, even with inflation, is a nice feature, and so is their worldwide convertibility.

Regulation, speculation, fraud, and cultural fashions all play a role in making new currencies risky; reader mbkennel yesterday asked an insightful question: "Are you up to loaning bitcoin or something less popular for 10 years?" Confidence in any given currency can be tested with the terms current holders are willing to accept to make loans payable in that same currency. (On the other hand, if large companies will accept it in payment, they've probably got an idea that a given currency will be around next month or next year.) If you've bought any form of crypto currency, what's been your experience, and what do you expect in 10 years? (Alternate Video Link)

The 'Radio Network of Things' Can Cut Electric Bills (Video) 172

Posted by Roblimo
from the trying-to-bring-the-electric-power-grid-into-the-21st-century dept.
We all love 'The Internet of Things.' Now imagine appliances, such as your refrigerator and hot water heater, getting radio messages from the power grid telling them when they should turn on and off to get the best electricity prices. Now kick that up to the electric company level, and give them a radio network that tells them which electric provider to get electricity from at what time to get the best (wholesale) price. This is what e-Radio is doing. They make this claim: "Using pre-existing and near ubiquitous radio signals can save billions of dollars, reduce environmental impact, add remote addressability and reap additional significant societal benefits."

Timothy noticed these people at CES. They were one of the least flashy and least "consumer-y" exhibitors. But saving electricity by using it efficiently, while not glamorous, is at least as important as a $6000 Android phone. Note that the guy e-Radio had at CES speaking to Timothy was Scott Cuthbertson, their Chief Financial Officer. It's a technology-driven company, from Founder and CEO Jackson Wang on down, but in the end, saving money is what they sell. (Alternate Video Link)

Talk to the World Through Ubi -- and Use Gestures, Too (Video) 38

Posted by Roblimo
from the not-quite-star-trek-but-getting-there dept.
'The Ubi is an always-on voice-activated computer ready to help. Just plug it in, talk to it and it'll help you connect with your world.' That Kickstarter project description back in 2012 helped UBI raise $229,594 even though they only hoped for $36,000. So now they sell Ubis for $299, as you can see for yourself by clicking the "BUY NOW" button in the upper right corner of www.TheUbi.com, their site's main page. A cynic might say that a decent Android phone can perform most Ubi functions, including a growing number of home automation control tasks, and that Android voice recognition gets better with each new release. But Ubi is cute, and round, and "you can talk through it to the ones you love."

That's great, but Android phones can do that, too. What a smartphone can't do is compete with Ubi Interactive, which may finally give us gesture-based computer input that is not only exciting in a Star Trek way, but is also practical for home and business use. This, along with Kinect, looks like a product that has a solid future ahead of it. (Alternate Video Link)

EnOcean Wireless Sensors Don't Need Batteries (Video) 46

Posted by Roblimo
from the almost-like-heinlein's-gramps-schneider-in-magic-inc. dept.
'The EnOcean technology is an energy harvesting wireless technology used primarily in building automation systems; but is also applied to other applications in industry, transportation, logistics and smart homes,' says Wikipedia. There's also a Siemans spinoff company called EnOcean, and today's video is an interview with its president, Jim O'Callaghan. But EnOcean technology is the real star here. The idea is that energy-efficient sensors can be powered by energy harvesting, i.e. drawing energy from their surroundings, including such low-level sources as light, temperature changes, and pressure, which can be the pressure of your finger on a switch or even changes in barometric pressure. The EnOcean Alliance has a professionally-produced video that describes their technology and notes that self-powered wireless sensors not only save energy but save miles of wire between sensor nodes and controllers, which means it's possible to install more sensors sensing more parameters than in the past.

DuinoKit Helps Teach Students About Electronics (Video) 61

Posted by Roblimo
from the you-don't-even-have-to-know-how-to-solder dept.
This is something Timothy Lord ran across a few months ago at a Maker Faire near Atlanta: The DuinoKit. Think of it as a fancier (and pricier) version of the venerable Radio Shack Electronic Learning Labs and you won't be far off. Plus, as the name DuinoKit implies, it's based on an Arduino, which means that right off the bat it packs a lot more learning punch than the Radio Shack kit. DuinoKit was financed by a KickStarter campaign that asked for $19,500 and raised $57,478 from 250 backers. And for those of you who worry about being called nerds because you're carrying a DuinoKit around, you can relax. It comes in a 'Secret Agent Carrying Case.' Really. Read their What is the DuinoKit? Web page carefully and you'll see. (Alternate Video Link)

LinuxFest Northwest 2015 Will be Held April 25 and 26 (Video) 21

Posted by Roblimo
from the the-coolest-conference-in-our-country's-upper-left-hand-corner dept.
Their website says, 'Come for the code, stay for the people! We have awesome attendees and electrifying parties. Check out the robotics club, the automated home brewing system running on Linux, or the game room for extra conference fun.' This is an all-volunteer conference, and for a change the volunteers who run it are getting things together far in advance instead of having sessions that don't get scheduled until a few days before the conference, which has happened more than once with LFNW.

So if you have an idea for a session, this is the time to start thinking about it. Sponsors are also welcome -- and since LFNW sponsorships regularly sell out, it's not to soon to start thinking about becoming a sponsor -- and if you are part of a non-profit group or FOSS project, LFNW offers free exhibit space because this is a conference that exists for the community, not to make money for a corporate owner. But don't delay. As you can imagine, those free exhibit spots tend to fill up early. (Alternate Video Link)

Attorney Yasir Billoo Explains NDA Law (Video) 38

Posted by Roblimo
from the sometimes-you-need-to-know-a-little-about-law-even-if-you-don't-want-to dept.
Yasir Billoo, an attorney with Golden & Grimes in Miami, Florida, is licensed to practice law in both Florida and California, and works heavily in the areas of business/commercial law, employment and labor, and civil appeals. Yasir also has a business-oriented blog titled Small Business Law.

In this Slashdot video interview hosted by Timothy Lord, Yasir gives what is essentially a primer on the law behind Non-Disclosure Agreements (NDAs) and how they differ from Non-Competes. Sooner or later you're going to encounter -- or even write -- an NDA, and you'd better know the law behind what you're doing. Naturally, today's interview isn't specific legal advice about a particular situation. If you want that, you need to hire a lawyer to advise you. But Yasir (a long-time Slashdot reader. BTW) has shared enough knowledge in this interview that it will help you deal with many NDA situations on your own, and how to tell when you really should have a lawyer by your side.

samzenpus (5) writes "Jonty Hurwitz is an artist with a degree in engineering who says each one of his pieces is "a study on the physics of how we perceive space and is the stroke of over 1 billion calculations and algorithms." Recently, his nano sculpture project drew a lot of attention. With help from the Weizmann Institute of Science and using a 3D printing technique by the Institute of Microstructure Technology at the Karlsruhe Institute of Technology, Hurwitz created a number of sculptures that were so small they could fit in the eye of a needle, or on a human hair. Jonty has agreed to answer any questions you have big or very small. As usual, ask as many as you'd like, but please, one per post."

An Algorithm To Prevent Twitter Hashtag Degeneration 162

Posted by samzenpus
from the read-all-about-it dept.
Bennett Haselton writes The corruption of the #Ferguson and #Gamergate hashtags demonstrates how vulnerable the hashtag system is to being swamped by an "angry mob". An alternative algorithm could be created that would allow users to post tweets and browse the ones that had been rated "thoughtful" by other users participating in the same discussion. This would still allow anyone to contribute, even average users lacking a large follower base, while keeping the most stupid and offensive tweets out of most people's feeds. Keep reading to see what Bennett has to say.

Make a Kids' Power Wheel Toy Awesome for $500 (Video) 39

You can spend less than $500 if you like. That's the maximum amount allowed if you're competing in the Power Racing Series. Interviewee Josh Lee is a member of the Southern Polytechnic State University Electric Vehicle Team. The modified electric 'ride on' toy they showed off and raced at Maker Faire Atlanta (where this video was made) is just one of their many projects. And, obviously, they're just one of many 'slightly deranged' teams involved in learning about and building electric vehicles. (Alternate Video Link)
