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

'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.

Lucky you.

About a year ago, I started getting fax calls to my phone at all hours of the day and night. Worse, they were from a large number of different sources. As if that weren't bad enough, most of these sources were international, leading to garbled CID, if any CID at all, making it impossible to put a block on them (the form to block a number wouldn't accept any numbers not of the US-standard NPA-NXX-XXXX format). It was fucking ridiculous.

CES 2015: WakaWaka Sheds Light On Technology, Profit, and Philanthropy (Video) 17

Camille van Gestel and co-founder Maurits Groen started solar-centric manufacturer WakaWaka with an explicit aim other than making money, though he's certainly not opposed to making some along the way. So it's not a non-profit, but van Gestel calls WakaWaka, which was named in a roundabout way after the Shakira song, a "purpose-driven company," with that purpose being -- no exaggeration needed -- to cast light on the world. They're doing just that, with the aid of recycled materials, low-power LEDs, and efficient solar cells. As a result, one of the portable light products that the group has created has become one of the most valued possessions among people displaced by the war in Syria, and more are lighting up villages in Haiti and elsewhere. I talked with Van Gestel at this year's CES, where the company's picked up a pair of CES Innovation Awards, and he has some advice for people who'd like to turn their technical skills to philanthropic endeavors, especially ones that involve hardware or technical infrastructure. Some of it can be summed up as "Spread the wealth, but don't do it for free." Between ongoing feedback gathered from users, a buy-one-give-one style distribution system, and requiring participation by recipients, he says WakaWaka has been able to reach people with their solar lighting products in a way that's much more valuable than just dumping hardware on them, and along the way has gotten a lot of feedback from the buyers whose purchases subsidize the company's non-profit activities.

Comment Re:ATF Ruling 2015-1 Manufacturing and Gunsmithing (Score 1) 573

Which reminds me- is a firearm truly the best way to create a projectile weapon on a 3D printer?

It seems to me that there should be a way to exceed a firearm's muzzle velocity, with a properly designed kinetic spring of some sort, thus building a weapon that requires neither metal nor gunpowder.

DuinoKit Helps Teach Students About Electronics (Video) 61

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)

Submission + - Seismological Society of America Claims Fracking Reactivated Ohio Fault (seismosoc.org) 1

eldavojohn writes: There have been suspicions that fracking has caused minor earthquakes in Ohio but last year seismic data recorded by the Earthscope Transportable Array was analyzed by the Seismological Society of America using template matching and has resulted in a new publication and press release making the statement that Hilcorp Energy's fracking in Poland Township in March of 2014 "did not create a new fault, rather it activated one that we didn’t know about prior to the seismic activity." The earthquakes occurred in the Precambrian basement and lead the researchers to posit that further unknown faults may be activated by fracking. The press release ends with urging for "close cooperation among government, industry and the scientific community as hydraulic fracturing operations expand in areas where there’s the potential for unknown pre-existing faults."

Submission + - SWAT teams in MA assert they are private entitites not subject to FOA (eagletribune.com)

sam_handelman writes: The North Eastern Massachusetts Law Enforcement Council, an umbrella organization for SWAT Teams in MA, has asserted in court that they are a private entity not subject to freedom of information act requests. According to a report in the local paper, the Eagle-Tribune They have taken down their website, which was cited by the ACLU and contained the following gem: that NEMLEC was established in 1963 out of a fear and distrust of civil rights advocates.

Comment Early Soviet Computing? (Score 4, Interesting) 80

Alexander Stepanov, I have never had a chance to ask someone as qualified as you about this topic. I grew up on the opposite side of the Iron Curtain and have constantly wondered if (surely there must have been) alternative computing solutions developed in the USSR prior to Elbrus and SPARC. So my question is whether or not you know of any hardware or instruction set alternatives that died on the vine or were never mass fabricated in Soviet times? I don't expect to you to reveal some super advanced or future predicting instruction set but it has always disturbed me that these things aren't documented somewhere -- as you likely know failures can provide more fruit than successes. Failing that, could you offer us any tails of early computing that only seem to run in Russian circles?

If you can suggest references (preferably in English) I would be most appreciative. I know of only one book and it seems to be a singular point of view.

Video What's the Future of Corporate IT and ITSM? (Video) 50

Our headline is the title of a survey SysAid did at Fusion, a "gathering of seasoned IT directors, service management implementers, and business analysts" that took place in early November. As Sysaid's marketing VP, Sophie Danby was the person who designed and implemented the survey, which consisted of only three questions: 1) Where do you see the corporate IT department in five years’ time? 2) With the consumerization of IT continuing to drive employee expectations of corporate IT, how will this potentially disrupt the way companies deliver IT? 3) What IT process or activity is the most important in creating superior user experiences to boost user/customer satisfaction? || You can obviously follow the first link above and see the survey's results. But in the video, Sophie adds some insights beyond the numerical survey results into near-future IT changes and what they mean for people currently working in the field.
