Can the Lix 3D Printing Pen Actually Work? 90

szczys (3402149) writes "Brian Benchoff used science and math to prove that the performance shown in the Lix Kickstarter video is questionable at best. Check his evidence and see if he's done an appropriate job of debunking the functionality presented." From the Hackaday post: "While we know the video is an outright misrepresentation of what any USB 3 powered device can do, We can’t figure out if the Lix is a viable product. We’re turning to you. Can you figure out if the Lix pen actually works? All we know is the Lix pen has a 4.5 Watt power supply from a USB 3 port. It’s possible for a USB 3 powered 3D printing pen to work, albeit slowly, but the engineering is difficult and we don’t know if the Lix team has the chops."

For the First Time Ever, the FAA Is Trying To Fine a Drone Hobbyist 297

Jason Koebler writes: "For the first time ever, the Federal Aviation Administration is trying to fine a hobby drone operator, a development that threatens to throw the whole hobby into disarray if the agency successfully levies the fine. While the FAA has explicitly said it doesn't want anyone flying drones commercially, it has never issued similar suggestions about hobby flight, which is why it has been just fine for some guy to fly a drone above a tornado, but illegal, in the FAA's eyes, for a journalist to do the same. That has changed, according to the agency. A spokesperson for the FAA told me that the agency 'has proposed a civil penalty against an individual in New York City. The operator, who is a hobbyist, flew a drone carelessly or recklessly and violated air traffic rules as well. He ran the drone into a couple of buildings and it crash-landed 20 feet from a person (video).'"

Man Builds DIY Cellphone Using Raspberry Pi 83

Photographer and software engineer Dave Hunt has posted an article about his most recent project: a DIY cellphone based on a Raspberry Pi (he calls it a PiPhone). It has a touchscreen dialing interface for making calls, and it's built with off-the-shelf components. The total bill of materials clocks in at about $158: $40 for the rPi, $35 for the 320x240 touchscreen, $15 for the LiPo battery, $48 for the GSM module, and about $20 for miscellaneous other minor parts. Hunt says, '[The GSM/GPRS module] allow us to send standard AT commands to it to make calls, hang up, send texts, data etc. Overall a very clever module. Towards the bottom of the white PCB, you can see the SIM Card, which allows the module to associate with my local GSM network, and it’s using a regular prepaid SIM card, bought in my local phone store for €10. Below the GSM module, you can see the on.off switch and a DC-DC converter, which converts the 3.7volts from the LiPoly battery to 5volts needed by everything else.' He points out that the phone is not terribly practical, but it's a neat project. Hunt has done several others, including turning the Raspberry Pi into a controller for time-lapse photography. He'll be publishing the code he wrote for the PiPhone next week.

Anonymous' Airchat Aim: Communication Without Need For Phone Or Internet 180

concertina226 (2447056) writes "Online hacktivist collective Anonymous has announced that it is working on a new tool called Airchat which could allow people to communicate without the need for a phone or an internet connection — using radio waves instead. Anonymous, the amorphous group best known for attacking high profile targets like Sony and the CIA in recent years, said on the project's Github page: 'Airchat is a free communication tool [that] doesn't need internet infrastructure [or] a cell phone network. Instead it relies on any available radio link or device capable of transmitting audio.' Despite the Airchat system being highly involved and too complex for most people in its current form, Anonymous says it has so far used it to play interactive chess games with people at 180 miles away; share pictures and even established encrypted low bandwidth digital voice chats. In order to get Airchat to work, you will need to have a handheld radio transceiver, a laptop running either Windows, Mac OS X or Linux, and be able to install and run several pieces of complex software." And to cleanse yourself of the ads with autoplaying sound, you can visit the GitHub page itself.

Skilled Manual Labor Critical To US STEM Dominance 367

Doofus writes: "The Wall Street Journal has an eye-catching headline: Welders Make $150,000? Bring Back Shop Class. Quoting: 'According to the 2011 Skills Gap Survey by the Manufacturing Institute, about 600,000 manufacturing jobs are unfilled nationally because employers can't find qualified workers. To help produce a new generation of welders, pipe-fitters, electricians, carpenters, machinists and other skilled tradesmen, high schools should introduce students to the pleasure and pride they can take in making and building things in shop class. American employers are so yearning to motivate young people to work in manufacturing and the skilled trades that many are willing to pay to train and recruit future laborers. CEO Karen Wright of Ariel Corp. in Mount Vernon, Ohio, recently announced that the manufacturer of gas compressors is donating $1 million to the Knox County Career Center to update the center's computer-integrated manufacturing equipment, so students can train on the same machines used in Ariel's operations.' How many of us liked shop? How many young people should be training for skilled manufacturing and service jobs rather than getting history or political science degrees?"

$42,000 Prosthetic Hand Outperformed By $50 3D Printed Hand 288

An anonymous reader writes "A man named Jose Delgado was so used to using a $42,000 myoelectric prosthetic hand for the last year that he didn't realize that there were other options out there. Although Delgado, born without a left hand, was able to obtain the hand via his insurance, he found that a 3D printed 'Cyborg Beast,' an open source hand which costs just $50 to print, actually was more comfortable and performed better than the device which costs 840 times as much money."

Ask Slashdot: Which Router Firmware For Bandwidth Management? 104

First time accepted submitter DeathByLlama (2813725) writes "Years ago I made the switch from DD-WRT to Tomato firmware for my Linksys router. I lost a couple features, but gained one of the best QoS and bandwidth management systems I have seen on a router to date. Admins can see graphs of current and historical bandwidth usage by IP, set minimum and maximum bandwidth limits by IP range, setup QoS rules, and see and filter graphs and lists of current connections by usage, class or source/destination — all from an elegantly designed GUI. This has allowed me to easily and intelligently allocate and adjust my network's bandwidth; when there is a problem, I can see where it's coming from and create rules around it. I'm currently using the Toastman's VPN Tomato firmware, which has about everything that I would want, except for one key thing: support for ARM-based routers (only Broadcom is supported). I have seen other firmware projects being actively developed in the last few years, so in picking a new 802.11ac router, I need to decide whether Tomato support is a deal-breaker. With solid bandwidth management as a priority, what firmware would you recommend? Stock Asuswrt? Asuswrt-Merlin? OpenWRT? DD-WRT? Tomato? _____?"

3D Display Uses Misted Water 65

An anonymous reader points out work at the University of Bristol into interactive, 3-D displays created by projecting light on misted water. "These personal screens are both see-through and reach-through. The see-through feature provides direct line of sight of the personal screen and the elements behind it on the tabletop. The reach-through feature allows the user to switch from interacting with the personal screen to reaching through it to interact with the tabletop or the space above it. The personal screen allows a range of customisations and novel interactions such as presenting 2D personal content on the screen, 3D content above the tabletop or supplementing and renewing actual objects differently for each user."

Raspberry Pi's Eben Upton: How We're Turning Everyone Into DIY Hackers 90

redletterdave writes "Eben Upton is the CEO of the Raspberry Pi Foundation's trading company, where he oversees production and sales of the Raspberry Pi. In a lengthy interview with ReadWrite, Upton shares how he invented Raspberry Pi, and what's coming next for the $35 microcomputer. Quoting: 'There's a big difference between [just] making a platform like Raspberry Pi available and offering support for it. I think if you just make it available, you'll find one percent of eight-year-olds will be the one percent who love that sort of thing and will get into it, regardless of how much or how little support you give them. ... [S]ince we can afford to pay for the development of educational material, we can afford to advocate for good training for teachers throughout this. There's an opportunity to get more than one percent. There's an opportunity to reach the bright kids who don't quite have the natural inclination to personally tackle complicated technical tasks. If you give them good teaching and compelling material that's relevant and interesting to them, you can reach ten percent, twenty percent, fifty percent, many more. We look back to the 1980s as this golden era [of learning to program], and in practice, only a very few percent of people were learning to program to any great degree. ... I think the real opportunity for us now, because we can intervene on the material and teacher training levels, we can potentially blow past where we were in the 1980s.'"

3D-Printed UAV Can Go From Atoms to Airborne in 24 Hours 77

Zothecula (1870348) writes "Because 3D printing allows one-off items to be created quickly and cheaply, it should come as no surprise that the technology has already been used to produce unmanned aerial vehicles, or UAVs. Engineers at the University of Sheffield's Advanced Manufacturing Research Center (AMRC), however, have taken things a step farther. They've made a 3D-printed UAV airframe that's designed to minimize the amount of material needed in its construction, and that can be printed and in the air within a single day."

Tesla Model S Has Hidden Ethernet Port, User Runs Firefox On the 17" Screen 208

New submitter FikseGTS (3604833) writes "A Tesla Model S owner located a 4 pin connector on the left side of the Tesla Model S dashboard that turns out to be a disguised ethernet networking port. After crafting his owns patch cable to connect with the Tesla's port, a networking connection was established between the Tesla Model S and a laptop computer. The Model S is running a 100 Mbps, full duplex ethernet network and 3 devices were found with assigned IP addresses in the 192.168.90.0 subnet. Some ports and services that were open on the devices were 22 (SSH), 23 (telnet),53 (open domain), 80 (HTTP), 111 (rpcbind), 2049 (NFS), 6000 (X11). Port 80 was serving up a web page with the image or media of the current song being played. The operating system is modified version of Ubuntu using an ext3 filesystem. Using X11 it also appears that someone was able to somewhat run Firefox on both of the Model S screens. Is a jailbroken Tesla Model S on the way?" Some more details on this front would be appreciated, for anyone who has a Tesla they'd like to explore.

Intel Upgrades MinnowBoard: Baytrail CPU, Nearly Halves Price To $99 92

DeviceGuru (1136715) writes "Intel and CircuitCo have revealed a smaller, faster, 2nd-gen MinnowBoard open SBC based on an Atom E3800 SoC and supported by both Android 4.4 and various standard Linux OSes. The MinnowBoard Max, which will ship in Q3 starting at $99, blows past the original MinnowBoard (Slashdot video) on price, performance, and energy consumption. The 3.9 x 2.9-inch Max's $99 starting price includes a 64-bit 1.46GHz Intel Atom E3815 (Bay Trail-T) CPU, 1GB RAM and 8GB SPI flash, and coastline ports for MicroSD, Micro-HDMI, GbE, dual USB, and SATA. Unlike the original MinnowBoard, the Max provides two expansion connectors: a low-speed header, with signals similar to the Arduino's Shield connector; and a high-speed connector, which can support mSATA and mini-PCIe sockets on expansion modules, among other interfaces. Although the Max's design supports CPUs up to Intel's quad-core 1.91GHz (10W TDP) E3845, only two choices shown initially at MinnowBoard.org, with the higher-end $129 model stepping up to a 1.33GHz dual-core E3825 plus 2GB RAM.."

The 3D Economy — What Happens When Everyone Prints Their Own Shoes? 400

cold fjord writes: "According to Reason, 'Last May, Cody Wilson produced an ingeniously brief but nuanced manifesto about individual liberty in the age of the ever-encroaching techno-state-a single shot fired by a plastic pistol fabricated on a leased 3D printer. While Wilson dubbed his gun The Liberator, his interests and concerns are broader than merely protecting the Second Amendment. ... Wilson is ultimately aiming for the 'transcendence of the state.' And yet because of the nature of his invention, many observers reacted to his message as reductively as can be: 'OMG, guns!'... But if armies of Davids really want to transcend the state, there are even stronger weapons at their disposal: toothbrush holders, wall vases, bottle openers, shower caddies, and tape dispensers. ... In many ways, it's even harder to imagine a city of, say, 50,000 without big-box retailers than it is to imagine it without a daily newspaper. So perhaps 3D printing won't alter our old habits that substantially. We'll demand locally made kitchen mops, but we'll still get them at Target. We'll acquire a taste for craft automobile tires, but we'll obtain them from some third party that specializes in their production. Commercial transactions will still occur. But if history is any guide, more and more of us will soon be engaging in all sorts of other behaviors too. Making our own goods. Sharing, swapping, and engaging in peer-to-peer commerce. Appropriating the ideas and designs of others and applying them to our own ends.'"

Operation Wants To Mine 10% of All New Bitcoins 275

An anonymous reader writes: "Mining new Bitcoins is computationally expensive — you can't expect to do much on your standard home computer. Many miners have built custom rigs to mine more efficiently, but it was only a matter of time until somebody went industrial. Dave Carlson's goal is to mine 10% of all new Bitcoins from now on. He's built literally thousands of units. They collectively use 1.4 million BitFury mining chips, which are managed by a bunch of Raspberry Pis. 'The current rigs each contain 16 boards, with each board containing 16 BitFury chips, for a total of 256 mining chips on each rig. Carlson said about 90,000 processor boards have been deployed, which would put the number of rigs at about 5,600. A new board [being designed] will have 756 chips on each rig instead of 256.' Carlson says his company spent $3-5 million to get everything set up. They current generate 7,000 — 8,000 Bitcoins per month, which, at current rates, would be worth over $4 million."

How 3D Printer Maker Aleph Objects Pushes the Open Source Envelope 51

Lemeowski (3017099) writes "In a time where there's a 'gold rush' for 3D printing patents, there's one company that's doing everything it can to keep its 3D printers as open as possible. Jeff Moe, CEO of Aleph Objects, said in an interview with Opensource.com that his company's strategy is 'to not patent anything, but to establish prior art as soon as we can. So when we develop things we try to push it out there as soon as possible and hope to establish prior art if there isn't prior art already. That allows us to develop a lot more quickly.' The company makes the Lulzbot 3D printers, and goes to the extreme of publishing every last detail about its printers, Moe said, including syncing its internal file system that it uses to share files on the development of the machine to the public every hour so you can see what they're doing."
