Justin McLean is probably best-known for his work with Apache Flex. He also started playing with open source hardware before Arduino, and now works with systems like Fritzing, an open source hardware initiative that can take you all the way from initial concept to production-ready PCBs you can have made by a production house -- or make yourself if that's the way you roll. This can be an educational activity, a way to make prototype boards for potential Internet of Things products or even just a fun way to occupy yourself by making LEDs light up.

An anonymous reader writes: Over on Forbes, Jono Bacon writes about the emergence of an open drone ecosystem spearheaded by the recently announced 3D Robotics SOLO which is largely Open Source and has an Open Source SDK. Bacon's argument is that innovation comes from where we least expect it, so open access to the code and tools is critical in helping the burgeoning drone ecosystem to thrive, solve problems, and grow. See also our videos interviews with open-source drone programmers / users John Hawley, Clay McLure, and Mark F. Brown and Joel Rozenweig at the recent Embedded Linux Conference, where Bacon was also a speaker.

agent elevator writes: UT Austin engineers have come up with a software fix that corrects for the errors GPS has when using the tiny antennas on smartphones. They demoed it using a VR setup and got 2-cm accuracy. For now it runs on a separate processor from the smartphone, but they say they'll fix that. The demo appears to have been done on a rooftop. VR. Outside. On a roof. Doesn't seem like a good idea, does it?

SonicSpike writes with word that Cody Wilson, whose projects to create (and disseminate the plans for) printable guns have fascinated some and horrified others, is not going to quietly comply with the U.S. State Deparment's demand that he remove such plans from the internet. Wilson, says Wired, is picking a fight that could pit proponents of gun control and defenders of free speech against each other in an age when the line between a lethal weapon and a collection of bits is blurrier than ever before. Wilson's gun manufacturing advocacy group Defense Distributed, along with the gun rights group the Second Amendment Foundation, on Wednesday filed a lawsuit against the State Department and several of its officials, including Secretary of State John Kerry. In their complaint, they claim that a State Department agency called the Directorate of Defense Trade Controls (DDTC) violated their first amendment right to free speech by telling Defense Distributed that it couldn't publish a 3-D printable file for its one-shot plastic pistol known as the Liberator, along with a collection of other printable gun parts, on its website.

You can call Bob Paulin 'Coach' and he'll probably respond, because he's been coaching youth football since 2005. Now he's also coaching what you might call 'youth science and technology' as the Chicagoland organizer of Devoxx4Kids.org. A motto on the group's website says, 'Game programming, robotics, engineering for kids in a fun way!' And that's what the group is all about, as Bob says in this video (and in the accompanying transcript for those who prefer reading over watching).

Mark F. Brown and Joel Rozenweig build autonomous drones; that is, drones that don't need an operator every second. You tell the autonomous drone, "Pick up package # 941A at the loading dock and deliver it to 451 Bradbury St.' and off it goes. It's going to be a while yet before that happens, but one day....

Back in the present, dronemaking is still a hobby for Mark and Joel, something they do for fun after spending their workdays as software engineers at Intel. Joel says there is 'remarkably little' crossover between their jobs and their hobby, and that (so far) Intel has contributed little beyond some Edison modules (which you can buy for less than $50) and travel to the Embedded Linux Conference, where they gave a talk accompanied by these slides. NOTE: We have a little bonus for you today. We try to keep videos to 10 minutes or less, but we have no such constraints on transcript length.

An anonymous reader writes: At Microsoft's Build 2015 developer conference today, Steve Guggenheimer, Microsoft vice president of developer and platform evangelism, announced new 3D printing features in Windows 10. More specifically, Autodesk Spark is being integrated into Microsoft's latest and greatest operating system. Spark is a platform for building 3D printing software, hardware, materials, and services. Adding it to Windows 10 is a big win for Autodesk.

XxtraLarGe writes: I work for a small liberal arts college, and have been asked to research makerspaces. I have done a bunch of initial research which tells me a lot about equipment being used, as well as location, etc., but what I'm not finding are what to know before you start, or what it takes to make the effort worthwhile.

I'd be interested in hearing from other educators, staff, students and other maker community members on Slashdot that had makerspaces at their schools or community — can be any level — and what was the experience like? 3D printer, 3D scanner & Laser cutting machines seem to be a given, so I'd like to hear what kinds of think-outside-the-box equipment/materials did you have? We are considering putting it in our library, which seems to be a popular choice with most schools. There's also the possibility of having it somewhere in town that it could be more accessible to members of the community, maybe even as a co-op.

An anonymous reader writes: In the Little Devices Lab at MIT, Jose Gomez-Marquez builds medical tools using a DIY mindset. He's designing cheap alternatives to existing hospital equipment to help spread high-quality medical care around the world. Gomez-Marquez is at the forefront of a large and often-unrecognized group of DIY medical tool builders. Together they are challenging the idea that staying healthy requires extraordinarily expensive, sophisticated equipment built by massive corporations. Harnessing this inventive energy, he argues, could improve the health of thousands of people around the world.

According to Wikipedia, 'Project Ara is the codename for an initiative that aims to develop an open hardware platform for creating highly modular smartphones.' Google is the sponsor, and the project seems to be moving faster than some people expect it to. There's a Project Ara website, of course, a GitHub repository, a Facebook page, even an Ara subreddit. During his conversation with Timothy Lord, Ara firmware project lead (and spokesman) Marti Bolivar said it won't be long before prototype Ara modular phones start user testing. Meanwhile, if you want to see what Marti and his coworkers have been up to lately, besides this interview, you can read a transcription of his talk (including slides) from the January Project Ara Developers Conference in Singapore.

frank249 writes: In the Star Trek universe, transparent aluminum is used in various fittings in starships, including exterior ship portals and windows. In real life, Aluminium oxynitride is a form of ceramic whose properties are similar to those of the fictional substance seen in Star Trek. It has a hardness of 7.7 Mohs and was patented in 1980. It has military applications as bullet-resistant armor, but is too expensive for widespread use.

Now, there has been a major breakthrough in materials science. After decades of research and development, the U.S. Naval Research Laboratory has created a transparent, bulletproof material that can be molded into virtually any shape. This material, known as Spinel (magnesium aluminate), is made from a synthetic powdered clay that is heated and pressed under vacuum into transparent sheets. Spinel weighs just a fraction of a modern bulletproof pane.

An anonymous reader writes in with this BBC story about the niche market of 3D printed "selfie" models. By now we're familiar with tales of 3D-printed marvels, from guns to duck prosthetics. But when I traveled to a physics conference in March, I wasn't expecting to end up with a full colour printout of myself. However, at a small stall that popped up on Industry Day at the American Physical Society's March meeting — that is precisely the service that was being offered. I stepped on to a little rotating platform, tried to stand still for a few awkward minutes while a camera scanned me up and down, and then filled out a form. A few weeks later, a box has arrived in the post. Somewhere inside it, my two-inch twin is waiting for me to overcome my trepidation and show him the light of day. But I'm in no hurry; it all seems a bit... odd. The box sits on my desk for several days. Even though getting 'printed' puts me in the illustrious company of Barack Obama and Richard III, I'm unsure about my decision. What, I wonder, does someone do with a small selfie in statue form? Where does this business find its customers?

New submitter Adrian Harvey writes The New Zealand based commercial space company Rocket Lab has unveiled their new rocket engine which the media is describing as battery-powered. It still uses rocket fuel, of course, but has an entirely new propulsion cycle which uses electric motors to drive its turbopumps.

To add to the interest over the design, it uses 3D printing for all its primary components. First launch is expected this year, with commercial operations commencing in 2016.

John 'Warthog9' Hawley was the boss sysadmin on kernel.org before he jumped to Intel in April, 2014, as an open hardware technical evangelist. He last showed up on Slashdot in June, 2014, with his Dr. Who-inspired Robot K-9. Now he's talking about flight computers for quadcopters, specifically ones based on MinnowBoards. Last month (April 2015) he was speaking at the Embedded Linux Conference + Android Builders Summit. That's where he and Timothy Lord had this conversation about flight controllers for UAVs, which makes it a fitting sequel to yesterday's video, which was also about controlling drones with real-time Linux.

Jason Koebler writes MakerBot fired roughly 20 percent of its staff Friday. Figures from 2014 placed the company's ranks at 500, meaning the cuts could equate to roughly 100 employees. The orders came from new CEO Jonathan Jaglom, Motherboard was told. Employees are apparently being led out of the company's Brooklyn office by security today. "It's about 20 percent of staff," a MakerBot representative, who asked not to be identified because she had not received approval to speak to the press, told Motherboard. "Everyone suspected that something would be coming with the new CEO, and that there would be restructuring coming."

This is an interview with Clay McClure. He makes his living designing 'custom Linux software solutions for technology start-ups in Atlanta and the San Francisco Bay area.' He also works on Embedded Linux for autonomous drones. Here's a link to slides from a talk he gave on exactly that topic: Flying Penguins - Embedded Linux Applications for autonomous UAVs, and that's far from all he has to say about making Linux-controlled drones. However, for some reason Timothy and Clay didn't talk about using drones for target practice. Perhaps they can discuss that another time.

NOTE: We urge you to read the transcript of this interview even if you prefer watching videos; it contains material we left out of the video due to sound problems.

An anonymous reader writes: Jono Bacon explains that in the same way open source spawned millions of careers and thousands of companies, the same openness has massive potential when applied to products. It could potentially jumpstart a revolution in how we conceptualize, build, and share things and how we experiment and innovate to push the boundaries of science and technology. He outlines some steps for adapting open source principles to physical creations: "...we will need to create a premise of a blueprint bundle. In much the same way I can download a branch from Git or a tarball with some code, complete with build system, we will want to be able to download a single branch or tarball with the full software, hardware designs, and more for how to create an open product. ... we will need to figure out how we collaborate and improve different pieces of these projects. For example, if someone refines a 3D printed piece of a drone, how do they fork the blueprints, submit their changes, have them reviewed, and get them merged into the project? Another question could relate to automated testing: when building physical products we can't always afford to build and test new physical hardware for it to then crash and burn, so how can we have unit tests for hardware or test in a virtual setting?"

szczys writes Martin Maly rode the wave of computer evolution in the 1980's while living in the former Czechoslovak Republic. Computers themselves were hard to come by, peripherals were even more rare and so enthusiasts of the time hacked their own, like dot-matrix printers and computer mice. If your build was impressive enough, the government would adopt it and begin manufacturing the design somewhat widely. Was your first computer mouse built into a plastic spice container? We covered what the personal computer revolution was like in Eastern Bloc countries back in December.

While Timothy Lord was at SXSW, he chatted with Yuki Nishida of AgIC and learned about the company's conductive ink products. But AgIC wasn't the only company at SXSW showing off conductive ink. You could also meet the Electroninks people and see their Circuit Scribe product, which had a Kickstarter campaign a while back that raised $574,425.

This kind of product seems to be attractive to the kind of people who fund Kickstarter projects, and this bunch seems to have good resumes and some interesting, well thought-out products. There is apparently room in the 'draw circuits and learn electrical basics' market for both AgIC and Electroninks -- and probably for another dozen competitors, too.

angry tapir writes An inquiry by an Australian Senate committee has recommended the introduction of uniform laws across jurisdictions in the country "regulating the manufacture of 3D printed firearms and firearm parts." Although current laws are in general believed to cover 3D printed guns, there are concerns there may be inconsistencies across different Australian jurisdictions. Although there aren't any high-profile cases of 3D printed weapons being used in crimes in the country, earlier this year a raid in Queensland recovered 3D printed firearm parts.
