MojoKid writes "3D Printing start-up Ultimaker announced its second generation printer, the Ultimaker 2. The new printer features significant redesigns from the first iteration of the Ultimaker. The company says that the new machine is more accurate, more efficient, and it's even quieter at 49dB. Specifically, the Ultimaker 2 has a new CNC-milled case (that's all white with glowing sidewalls) with an OLED display, and its glass and aluminum build platform is designed to cool quickly so you can peel completed projects off more easily. The Ultimaker 2 can print with multiple materials, including PLA, ABS, and PVA, and is WiFi-compatible so you can print from a mobile device or computer. Ultimaker is also launching its Cura open source software, which the company claims can pre-process 3D files some 60 times faster than other open source applications and makes it easy to load and work with 3D files."

MTorrice writes "By attaching a lightweight, inexpensive device to the back of a smart phone, scientists can convert the phone into a sensitive fluorescence microscope. The attachment [paper abstract] allows the phone's camera to take pictures of single nanoparticles and viruses, possibly providing a portable diagnostic tool for health care workers in developing countries. For example, doctors in remote regions could use the technique to measure HIV viral loads in patients' blood samples, allowing the doctors to easily monitor disease progression and determine the best course of treatment."

The popular Cyanogen Mod distribution of the Android Open Source Project dropped a bombshell today: the founding members have formed a corporation (currently with a team of seventeen hackers) to work on the project with the founder of Boost Mobile as the CEO. Quoting the announcement: "You have probably seen the pace of development pick up drastically over the past few months. More devices supported, bigger projects such as CM Account, Privacy Guard, Voice+, a new version of Superuser, and secure messaging. We vastly improved our infrastructure. We’re doing more bug fixes, creating more features, and improving our communication. We think that the time has come for your mobile device to truly be yours again, and we want to bring that idea to everybody. ... So what does this all mean for the community? The first thing I wanted to do when I realized we were actually doing this, was tell everyone possible. But when starting a company, you have to think about the larger picture. This meant not announcing until the time was right, our house was in order and we would have something to show. I have seen open source projects come and go, some being bought out and closed, others stagnating and falling by the wayside. I don’t want to see this happen with CM."

An anonymous reader writes "A few months after releasing support for viewing models in .STL format, GitHub just added support for viewing changes to .STL formatted 3D models directly in the browser. 'How does this work? We take both versions of the model, and using binary space partitioning, we compute the added, removed, and unchanged parts. This is done using csgtool, a C library paired with a Ruby gem via FFI. These pieces are cached and displayed by the 3D viewer we already have, though we color them differently and play with their transparency to help illustrate the changes.'"

coop0030 writes "Adafruit has a new tutorial that will show you how to use your Raspberry Pi as a WiFi access point that blocks ads by default for any devices using it. This is really neat in that it would work for your Android or iOS device, your Xbox 360, TiVo, laptop, and more without needing to customize any of those devices other than to use your Raspberry Pi as the access point for WiFi. Using an ad-blocker can be useful for conserving bandwidth, helping out low-power devices, or for keeping your sanity while browsing the web!"

An anonymous reader writes "Using a Lego Mindstorms set, a Mac, and optical character recognition, Austrian professor Peter Purgathofer created a makeshift ebook copier. From the article: 'It's sort of a combination of high tech meets low. The scanning is done by way of the Mac's iSight camera. The Mindstorms set does two things: Hits the page-advance button on the Kindle (it appears to be an older model, like the one in the picture above), then mashes the space bar on the Mac, causing it to take a picture.' Purgathofer calls the creation a 'reflection on the loss of long established rights.' Check out the Vimeo video for a demonstration."

An anonymous reader sends this news from the Wall Street Journal: "A 19-year-old model helicopter enthusiast was killed Thursday when a toy helicopter he was flying struck him in the head, a law-enforcement official said. Victim Roman Pirozek 'was known to be aggressive in his flying and often executed tricks. He was executing a trick when he was struck,' the official said. Mr. Pirozek – depicted in [this YouTube video] he posted in July — was flying a remote-controlled helicopter worth about $2,000 when it struck him, cutting off the top of his head, the official said. The Woodhaven, Queens, resident was pronounced dead at the scene. His father was with him at the time of the accident, the official said."

In August Phil Shapiro wrote an article that asked the question, Can 50 Closed Chicago Schools Become 50 Makerspaces? Now, in September, we have a ruminative interview with him about schools, makerspaces, and how making places where kids (and adults) can make things and generally tinker with tools and get used to the idea of working with their hands to create new things and to repair old ones. For many of us in previous generations, our "makerspace" was our garage or basement, and our mentor was Dad. Today, this doesn't seem to be the case in a lot of homes. Besides, working with others is safer than working alone, and even if we bowl alone there is no good social or biological reason for us to create alone -- especially if we have a congenial makerspace nearby.

An anonymous reader notes that Skype is reportedly working on a 3D version of its messaging application. As reported by the BBC, an unnamed senior executive says that rumors to this effect are true. However, don't get too worked up about sending your avatar to school or to work just yet: Microsoft's corporate vice-president for Skype, Mark Gillett, says that "the capture devices are not yet there. As we work with that kind of technology you have to add multiple cameras to your computer, precisely calibrate them and point them at the right angle. ... We have it in the lab, we know how to make it work and we're looking at the ecosystem of devices and their capability to support it in order to make a decision when we might think about bringing something like that to market."

cartechboy writes "Two Ph.D. students from MIT have created a keyboard accessory, the Pavlov Poke, that shocks you every time you go onto Facebook. The project comes as a result of the students finding the waste over 50 hours a week combined on the social network (instead of working on their dissertations) So the pair created an Arduino-based keyboard hand-rest that shocks computer users who spend too much time checking the social network. The hack is 'intended to generate discussion' — not actually turn into a business." Inventor Robert Morris describes it as "something of a joke," but I'm sure there's a market out there.

dryriver writes with this excerpt from the BBC about the latest device from Makerbot: "A desktop device that can quickly scan objects so they can be replicated using a 3D printer has gone on sale. The Makerbot Digitizer, which costs $1,400 (£900), will be shipped to the first buyers in October. Demand for the machine appeared to overload the company's store when it went on sale on Thursday evening. The Digitizer is the latest product looking to bring 3D printing to mainstream technology users — but experts are sceptical. The machine is designed to allow the replication of objects without any need for the user to learn any 3D modelling software or have any other special expertise. The time it takes to scan an object varies, but one demonstration involving a small gnome was said to take around 12 minutes. "The MakerBot Digitizer is for early adopters, experimenters, and visionaries who want to be pioneers in Desktop 3D Scanning," the company says. "This includes, but is not limited to, architects, designers, creative hobbyists, educators, and artists.""

hypnosec writes "The CyanogenMod team has announced the release of version 10.2 nightly builds, which are based on Google's latest Android 4.3 Jelly Bean. The current nightly builds have been released for the Google Galaxy Nexus, HTC One, Samsung Galaxy S4, Samsung Galaxy S3, LG Optimus G, Sony Xperia Z, and Motorola Razr among others. As always, CyanogenMod team reminds that these are experimental."

Zothecula writes "A team at the Harvard School of Engineering and Applied Sciences (SEAS) has come up with a promising new way to create 3D images from a stationary camera or microscope with a single lens. Rather than expensive hardware, the technique uses a mathematical model to generate images with depth and could find use in a wide range of applications, from creating more compelling microscopy imaging to a more immersive experience in movie theaters."

Zothecula writes "The additive layer process of conventional 3D printers means they are usually limited to bottom up fabrication on three axes. Now, the LA-based NSTRMNT team has created a 3D printing process called suspended disposition that gets around gravity by printing objects within a gel. Not only does this allow freeform additive fabrication on six axes, it also enables an 'undo' function."

Via Engadget comes the news that Google's latest (and quickly sold-out) toy, the Chromecast, may soon be hacked out of one-trick-pony status; just a few days after it came out, the folks at GTV Hacker have successfully turned their attention to the Chromecast, and managed to exploit the device's bootloader and spawn a root shell. Some interesting findings, as explained in their blog post: "[I]t’s actually a modified Google TV release, but with all of the Bionic / Dalvik stripped out and replaced with a single binary for Chromecast. Since the Marvell DE3005 SOC running this is a single core variant of the 88DE3100, most of the Google TV code was reused. So, although it’s not going to let you install an APK or anything, its origins: the bootloader, kernel, init scripts, binaries, are all from the Google TV. We are not ruling out the ability for this to become a Google TV 'stick.'"

A few days ago, the CyanogenMod teamed teased a new project named Nemesis, a series of planned improvements to the user interface. An anonymous reader writes with news of the first part: a new camera application designed to replace the neglected stock Android camera app. From the article: "As cameras and camera software becomes an increasingly important part of our mobile experience, a great photography experience on your smartphone can make all the difference. The CyanogenMod project has decided to take smartphone photography a lot more seriously with the release of Focal, and all new camera app for CM users everywhere." Android Police also has an early look with screenshots. The menu system in particular looks a lot nicer to use than the current cumbersome interface to white balance/exposure/scene settings. Focal should be merged into nightly releases soon.

Travis Goodspeed has authored a blog post detailing his method of tracking low-earth-orbit satellites. Starting with an old Felcom 82B dish made for use on maritime vessels, he added motors to move it around and a webcam-based homemade calibration system. "For handling the radio input and controlling the motors, I have a BeagleBone wired into a USB hub. These are all mounted on the trunk of the assembly inside of the radome, sending data back to a server indoors. ... In order to operate the dish, I wanted both a flashy GUI and concise scripting, but scripting was the higher priority. Toward that end, I constructed the software as a series of daemons that communicate through a PostgreSQL database on a server inside the house. For example, I can run SELECT * FROM sats WHERE el>0 to select the names and positions of all currently tracked satellites that are above the horizon. To begin tracking the International Space Station if it is in view, I run UPDATE target SET name='ISS';. For predicting satellite locations, I wrote a quick daemon using PyEphem that fetches satellite catalog data from CelesTrak. These positions are held in a database, with duplicates filtered out and positions constantly updated. PyEphem is sophisticated enough to predict in any number of formats, so it's easy to track many of the brighter stars as well as planets and deep-space probes, such as Voyagers 1 and 2."

hypnosec writes "Adapteva has started shipping its $99 Parallella parallel processing single-board supercomputer to initial Kickstarter backers. Parallella is powered by Adapteva's 16-core and 64-core Epiphany multicore processors that are meant for parallel computing unlike other commercial off-the-shelf (COTS) devices like Raspberry Pi that don't support parallel computing natively. The first model to be shipped has the following specifications: a Zynq-7020 dual-core ARM A9 CPU complemented with Epiphany Multicore Accelerator (16 or 64 cores), 1GB RAM, MicroSD Card, two USB 2.0 ports, optional four expansion connectors, Ethernet, and an HDMI port." They are also releasing documentation, examples, and an SDK (brief overview, it's Free Software too). And the device runs GNU/Linux for the non-parallel parts (Ubuntu is the suggested distribution).

An anonymous reader writes "A new study by researchers in the Built Environment Research Group at the Illinois Institute of Technology shows that commercially available desktop 3D printers can have substantial emissions of potentially harmful nanosized particles in indoor air. Many desktop 3D printers rely on a process where a thermoplastic feedstock is heated, extruded through a small nozzle, and deposited onto a surface to build 3D objects. Similar processes have been shown to have significant aerosol emissions in other studies using a range of plastic feedstocks, but mostly in industrial environments. In this study, researchers measured ultrafine particle concentrations resulting from a popular commercially available desktop 3D printer using two different plastic feedstocks inside an office. Ultrafine particles (or UFPs) are small, nanosized particles less than 100 nanometers in diameter. Inhalation of UFPs may be important from a health perspective because they deposit efficiently in the lung and can even translocate to the brain. Estimates of emission rates of total UFPs in this study were high, ranging from about 20 billion particles per minute for a 3D printer utilizing a lower temperature polylactic acid (PLA) feedstock to about 200 billion particles per minute for the same type of 3D printer utilizing a higher temperature acrylonitrile butadiene styrene (ABS) feedstock. The emission rates were similar to those measured in previous studies of several other devices and indoor activities, including cooking on a gas or electric stove, burning scented candles, operating laser printers, or even burning a cigarette."

DeviceGuru writes "WigWag has developed a home automation kit that combines a Linux-based 6LoWPAN router with sensor units running the open-source Contiki IoT (Internet of Things) OS. Users can add ZigBee, Bluetooth, and other modules to expand the home network, and the WigWam development kit provides shield development boards for use with Arduino and Raspberry Pi SBCs. Users control the devices with a smartphone app (initially Android-based) and associated WigWag cloud service, which lets the devices remotely respond to sensor-based events such as motion detection, rain, noise, etc. Developers can create rules-based scripts for controlling devices using WigWag's open-source Javascript-based DeviceJS development environment. WigWag used a Kickstarter page to fund production and has already tripled its goal."
