Seen by some as products competing in a similar space, Andrej shows how the two devices can make the most of their unique features to complement each other, working together."

Sparrowvsrevolution writes in with a story at Forbes about Makerbot deleting gun component blueprints on Thingiverse. "In the wake of the Newtown, Connecticut shootings, the 3D-printing firm Makerbot has deleted a collection of blueprints for gun components from Thingiverse, its popular user-generated content website that hosts 3D-printable files. Though Thingiverse has long banned designs for weapons and their components in its terms of service, it rarely enforced the rule until the last few days, when the company's lawyer sent notices to users that their software models for gun parts were being purged from the site. Gun control advocates were especially concerned about the appearance of lower receivers for semi-automatic weapons that have appeared on Thingiverse. The lower receiver is the the 'body' of a gun, and its most regulated component. So 3D-printing that piece at home and attaching other parts ordered by mail might allow a lethal weapon to be obtained without any legal barriers or identification. Makerbot's move to delete those files may have been inspired in part by a group calling itself Defense Distributed, which announced its intention to create an entirely 3D-printable gun in August and planned to potentially upload it to Thingiverse. Defense Distributed says it's not deterred by Makerbot's move and will host the plans on its own site."

New submitter mihai.todor85 writes "It looks like Andrew 'bunnie' Huang has been quite busy lately, developing a nice open hardware laptop. He was even kind enough to provide all the schematics without NDA. For anybody interested in owning such a device, he says that he 'might be convinced to try a Kickstarter campaign in several months, once the design is stable and tested' if enough people are interested."

Today we're doing a live interview from 18:30 GMT until 20:30 GMT with long time contributor Luke Leighton of Rhombus Tech. An advocate of Free Software, he's been round the loop that many are now also exploring: looking for mass-volume Factories in China and ARM processor manufacturers that are truly friendly toward Free Software (clue: there aren't any). He's currently working on the first card for the EOMA-68 modular computer card specification based around the Allwinner A10, helping the KDE Plasma Active Team with their upcoming Vivaldi Tablet, and even working to build devices around a new embedded processor with the goal of gaining the FSF's Hardware Endorsement. Ask him anything. (It's no secret that he's a Slashdot reader, so expect answers from lkcl.)

coop0030 writes "Ladyada and pt had an old NeXT keyboard with a strong desire to get it running on a modern computer. These keyboards are durable, super clicky, and very satisfying to use! However, they are very old designs, specifically made for NeXT hardware: pre PS/2 and definitely pre-USB. That means you can't just plug the keyboard into a PS/2 port (even though it looks similar). There is no existing adapters for sale, and no code out there for getting these working, so we spent a few days and with a little research we got it working perfectly using an Arduino Micro as the go between."

lkcl writes about his effort to go further than others have, and actually have a processor designed for Free Software manufactured: "A new processor is being put together — one that is FSF Endorseable, contains no proprietary hardware engines, yet an 800MHz 8-core version would, at 38 GFLOPS, be powerful enough on raw GFLOPS performance figures to take on the 3ghz AMD Phenom II x4 940, the 3GHz Intel i7 920 and other respectable mid-range 100 Watt CPUs. The difference is: power consumption in 40nm for an 8-core version would be under 3 watts. The core design has been proven in 65nm, and is based on a hybrid approach, with its general-purpose instruction set being designed from the ground up to help accelerate 3D Graphics and Video Encode and Decode, an 8-core 800mhz version would be capable of 1080p30 H.264 decode, and have peak 3D rates of 320 million triangles/sec and a peak fill rate of 1600 million pixels/sec. The unusual step in the processor world is being taken to solicit input from the Free Software Community at large before going ahead with putting the chip together. So have at it: if given carte blanche, what interfaces and what features would you like an FSF-Endorseable mass-volume processor to have? (Please don't say 'DRM' or 'built-in spyware')." There's some discussion on arm-netbook. This is the guy behind the first EOMA-68 card (currently nearing production). As a heads ups, we'll be interviewing him in a live style similarly to Woz (although intentionally this time) next Tuesday.

An anonymous reader writes "Quoting liliputing: 'PengPod plans to start shipping 7 and 10 inch tablets with support for Linux as well as Google Android in January. The company, founded by Neal Peacock, has been raising money to help support software development for the tablets — and Peacock just wrote in to let us know the project has surpassed its initial $49,000 fundraising goal. In other words, the campaign will be fully funded and backers that pledged $120 or more should get their tablets starting in January if all goes according to plan.'" And, unlike many ARM SoCs, the kernel for the Allwinner A10 powering it is developed openly.

slashchuck writes "One of the drawbacks of Google's Nexus 4 was its lack of support for 4G LTE. Now comes a report from AnandTech that it's possible to enable partial LTE support on the device. It seems that a simple software update can allow the Nexus 4 smartphone to run on LTE Band 4. All users have to do is dial *#*#4636#*#* (INFO) or launch the Phone Info app. After that, choosing to connect to AWS networks should allow the Nexus 4 to run on LTE networks on Band 4. The AnandTech report states explicitly that the LG Nexus 4 only works on LTE Band 4, on 1700/2100MHz frequencies, and supports bandwidths of 5,10, and 20MHz."

An anonymous reader writes "Developers been working hard for the past few months to get Linux ported to the TI-Nspire calculator. The port is not yet fully stabilized nor quite ready for broad consumption and requires some user-level knowledge of Linux systems, but is definitely worth a try. Experimental support for root filesystem installed on USB mass storage is being worked on, so that Datalight's proprietary Flash FX/Reliance filesystem used by TI's OS isn't a limit anymore. This also means that the native TI-Nspire OS image is not replaced by the Linux system, and Linux can been booted on demand. Support for USB keyboard, X server, directFB, Wi-Fi (with the help of a powered USB hub) and text-based Internet browsing is progressively being added and tested."

Hugh Pickens writes "Josie Garthwaite writes that old electric car batteries degraded below acceptable performance levels for autos still have enough life to serve the grid for at least ten years with a prototype announced by GM and ABB lashing five Chevy Volt battery packs together in an array with a capacity of 10 kilowatt-hours — enough to provide electricity for three to five average houses for two hours. 'In a car, you want immediate power, and you want a lot of it,' says Alexandra Goodson. 'We're discharging for two hours instead of immediately accelerating. It's not nearly as demanding on the system.'" (Read on, below.)

An anonymous reader writes "Google's Nexus 4 sold out around the world very quickly this week, and while there was talk of very limited supply, apparently some key people managed to get their hands on it. That's right: the Nexus 4 has already been rooted."

An anonymous reader writes "The team behind CyanogenMod, one of the most popular community-driven, Android-based operating systems for phones and tablets, has announced that they're moving to Cyanogenmod.org after their .com domain was held ransom by a community member. He had been in control of the .com domain name for some time, but the team found out he was impersonating Cyanogen to make deals with community sites. When they removed his access to other parts of the CM infrastructure, he demanded $10,000 to relinquish control of the domain and threatened to change the DNS entries. When they refused to pay, he went through with it. The team is now disputing control of the domain with ICANN. They said, 'We will continue to be open about the what, when, how, but unfortunately, we may never know the "why" – though greed comes to mind. The team itself has not made a profit off of CM and that is not our goal. But to have one of our own betray the community like this is beyond our comprehension.'"

Penurious Penguin writes "Via LXer, an article from PCWorld describes the A13-OLinuXino, produced by OLIMEX. Similar, but distinct from the Raspberry Pi, the Linux-powered OLinuXino is touted as 'fully open,' with all CAD files and source-code freely available for both personal and commercial reuse. Its specs include an Allwinner A13 Cortex A8 1GHz processor, 3D Maili400 GPU, 512MB RAM, all packed into a nano-ITX form and fit for operation in industrial environments between -25C and 85C. The device comes with Android 4.0, but is capable of running other Linux distros, e.g., ArchlinuxARM."

"Reverberation is the persistence of sound in a particular space after the original sound is produced," says Wikipedia. More often than not, in studio recordings reverb is added digitally; virtually every FOSS or proprietary sound-editing program has a built-in reverb utility. But what if you're the sort of purist who prefers the analog sound of vinyl records to the digital sound of MP3s or CDs? What if you're the kind of musician who records at the original Sun Studio in Memphis to get that original rock and roll sound? That may be overly picky for most musicians, but there are some who would rather sound like Johnny Cash than Flavor Flav, and they're the ones who are going to insist on real analog reverb instead of twiddling a setting in Audacity. There are many types of analog reverbs, of course. One of the purest types, preferred by many audio purists, is the adjustable plate reverb, and Jim Cunnigham's Ecoplate is considered by many to be the best plate reverb ever -- which brings us to Mike Storey, who wanted an Ecoplate-type plate reverb so badly that he spent eight months building one. He'll run your audio files through it for a (highly negotiable) fee, and maybe give you a bit of advice if you want to build your own, although his biggest piece of advice for you (at the end of the video) to think long and hard before you become a home-brew reverberator, with or without advice and components from Jim Cunningham.

I like the video that appears to show a smartphone's camera being used as the basis of an input device for a laptop; can anyone out there better explain it?

jjp9999 writes "By using the same technology found in older modems, Thomas Tumino, vice president of the Hall of Science Amateur Radio Club, has invented an iPhone interface for ham radios. He told The Epoch Times, 'Today there are iPhone apps where you can use the systems in the phone — and its sound card, which is being used as a modem ... And then you connect that into your radio with an interface like this, that just isolates the telephone from the radio, and then you can do all sorts of things.'"
