An anonymous reader writes "My colleague at IEEE Spectrum, Eliza Strickland, looked at the home transcranial direct current stimulation (tDCS) movement. People looking to boost creativity, or cure depression, are attaching electrodes to their heads using either DIT equipment or rigs from vendors like Foc.us. Advocates believe experimenting with the tech is safe, but a neuroscientist worries about removing the tech from lab safeguards..."

An anonymous reader writes "Autodesk has announced that after the 2015 version of Softimage, which is scheduled for release next April, it will no longer provide software support. The publisher has confirmed the rumors last month, according to which Autodesk intends to terminate its software for 3D modeling and animation. 'We regret to inform you that the next version of Softimage 2015 will be the last,' can be read on the Autodesk website. 'This latest version will be released around April 14, 2014. Autodesk will continue to provide support for up to 30 April 2016. '"

Via Phoronix comes news that Debian has been ported to the OpenRISC architecture by Christian Svensson. Quoting his mailing list post: "Some people know that I've been working on porting Glibc and doing some toolchain work. My evil master plan was to make a Debian port, and today I'm a happy hacker indeed! ... If anyone want to try this on real hardware (would be very cool to see how this runs IRL), ping me on IRC [#openrisc on freenode] and I'll set you up with instructions how to use debootstrap - just point to a repo with the debs and you're all set, the wonders of binary distributions." For those who don't know, OpenRISC is the completely open source RISC processor intended as the crown jewel of the Opencores project. A working port of glibc and a GNU/Linux distribution is a huge step toward making use of OpenRISC practical. There's a screencast of the system in action, and source on Github (at posting time, it was a month out of date from the looks of it). Christian Svensson's Github account also has repos for the rest of the toolchain.

szczys writes "Gregory Charvat has been playing with and teaching others about entry-level radar concepts for a long time. Now he's sat down and explained how you can do it yourself inexpensively. He says, 'One enabling technology for Radar was the cathode ray tube (CRT), which facilitated a method of measuring the time delay between transmitted and received waveforms. ... Today, rather than using a CRT we can use high-speed digitizers. This offers the obvious advantage of applying signal processing to acquired data so that only moving targets are detected, tracking can be achieved, imaging, and a multitude of other modes. But for hobbyist and consumer projects we do not need this much power, range, and can not afford the cost. We need the ability to sense like a long range radar (detecting only moving targets, imaging, Doppler, signatures, etc) but at short ranges and at low costs.' Charvat then proceeds to walk through several options for the amatuer hardware hacker."

An anonymous reader writes "Shubham Banerjee, a seventh grader in California, has developed a braille printer made from a $350 Lego Mindstorms EV3 kit and some simple hardware. He calls the science fair project the Braigo. 'The Braigo's controller is set up to scroll through the alphabet. You choose a letter and it prints it out with tactile bumps on a roll of calculator paper. The print head is actually a thumbtack, which Banerjee settled on after also testing a small drill bit and a mechanical pencil. The first prototype isn't terribly fast, but it proves the concept works. Banerjee is working on improvements that will allow it to print full pages of text.'"

TAZ 3 is the fifth model in the LulzBot line of 3D printers by Aleph Objects, Inc. FSF has certified other models of LulzBot 3D printer for respecting privacy as well."

mspohr writes with this excerpt from The Register: "Spanish hackers have been showing off their latest car-hacking creation; a circuit board using untraceable, off-the-shelf parts worth $20 that can give wireless access to the car's controls while it's on the road. The device, which will be shown off at next month's Black Hat Asia hacking conference, uses the Controller Area Network (CAN) ports car manufacturers build into their engines for computer-system checks. Once assembled, the smartphone-sized device can be plugged in under some vehicles, or inside the bonnet of other models, and give the hackers remote access to control systems. 'A car is a mini network,' security researcher Alberto Garcia Illera told Forbes. 'And right now there's no security implemented.'"

An anonymous reader writes "Gamer rage is a common phenomenon among people who play online, a product of the intense frustration created by stressful in-game situations and an inability to cope. It can have significant impact on the gamer's ability to play well, and to get along with others. To combat this rage and train gamers to deal with the stress, visual designer Samuel Matson of Seattle has created the Immersion project, integrating a pulse sensor tied to a Tiny Arduino with Bluetooth into a headset to monitor the gamer's heart rate. The heart rate data is sent in real time to the gaming PC, where it is displayed in the game. Matson even created a simple FPS using the Unity game engine that varies the AI and gaming difficulty based on the user's heart rate. Using this system, the gamer is able to train themselves to recognize the stress and learn to control it, in order to make them a much more agreeable and competitive player."

An anonymous reader writes "Google's recent acquisition of Nest, the maker of smart thermostats and smoke detectors, has sparked concerns of future plans for the devices, and how Google's omnipresent thirst for information will affect them. Thus, a team of engineers at Spark sat down and roughed out a prototype for an open source version of Nest. It looks surprisingly good for such a short development cycle, and they've posted their code on Github. The article has a number of short videos illustrating the technology they used, and how they used it. Quoting: 'All in, we spent about $70 on components to put this together (including $39 for the Spark Core); the wood and acrylic were free. We started working at 10am and finished at 3am, with 3.5 engineers involved (one went to bed early), and the only work we did in advance was order the electronic components. We're not saying that you can build a $3.2 billion company in a day. But we are saying that you can build a $3.2 billion company, and it's easier now than it's ever been before.'"

An anonymous reader writes "Ok, fellow geeks... I have the luxury of finally building my dream home from scratch. It's going to be good sized (~4000 sq ft over 3 levels), and rather than run around at night to make sure my lights are off, doors are locked, garage is closed, etc, I really want to put in a home automation system. Since the walls aren't up, this is the time for complete flexibility as to my options. The last time I did a whole house, it was years ago, X10. Since then, lots of other protocols, both 'proprietary' and more general (like WiFi) have come on the market for devices — all better than what I've worked with in the past. What do you all have experience with and recommend as reliable, secure, and fairly easy to use? Something with a good chance for long term availability of parts and features would be a bonus."

A while ago you had the chance to ask inventor Alan Adler about making the perfect cup of coffee and throwing things really far. Below you'll find his best coffee brewing tips and the answers to those questions.

Tech educational collective The Geek Group, based in Grand Rapids, Michigan, has more than 25,000 members, scattered all over the world — most of whom have never been to their flagship location in Michigan. Sadly, a fire Thursday damaged one of the facilities at their Leonard Street Labs (damage report starts about 26 minutes into this video), the High Voltage Lab. Since there aren't that many places for amateurs and hobbyists to learn about high voltage (even with the growing number of maker spaces around the world), that leaves a hole that hopefully will soon be filled; lucky for anyone interested, The Geek Group welcomes volunteers.

schwit1 writes "Illinois passed a new state law that set back the efforts of the People for the Ethical Treatment of Animals (PETA), making the use of drones to interfere with hunters and fishermen prohibited. The law was created in response to PETA's plan to employ drones called "air angels" to monitor outdoors enthusiasts engaged in hunting and fishing nationwide."

DeviceGuru writes "A Russian startup called Virt2real has produced a small $120 Linux-based WiFi controller board for remote control and video observation applications, and has demonstrated its use in a remote controlled car. Inspired by Back to the Future and James Bond film Tomorrow Never Dies, Virt2real's Bond Car demo (YouTube video) shows a Vauxhall (Opel) Vectra being remotely controlled by an iPad via WiFi. The iPad interface includes touchscreen-based steering wheel, brakes, and accelerator, which are mirrored in the car by a mechanical contraption that physically turns the steering wheel and pushes the brake and accelerator pedals. The company is now accepting orders for the first 1,000 of its Virt2real controller board, and is working on a Virt2real-based Bond Car it that will work with most cars."

An anonymous reader writes with this excerpt from The Daily Dot:"On Monday evening, a bill aimed at thwarting the production and distribution of plastic 3-D printed weapons was blocked by Senate Republicans. ... The debate over the new legislation centered around the 1988 Undetectable Firearms Act, which bans the production and distribution of weapons that skirt 'walk through metal detectors.' The act has been renewed on two occasions since its passage. It was due to expire again on the 9th of December. The House voted to renew the bill last week. The rise of 3-D printing has made this year's renewal more complicated in the Senate. Many lawmakers, particularly Democrats, feel the current Undetectable Firearms Act inadequately addresses the rising threat posed by printed plastic weapons."

Arvydas Juskevicius (say that five times fast) is an independent software developer and hardware hacker based in London (which is where I got a chance to talk with him) who's decided to bring the useful LED signalling capabilities of many modern smartphones into the world of desktop or laptop computers. With his £10 BlinkStick kit (£15 pre-assembled), you get a programmable multi-color LED that's about the size of a flash memory key. Deceptively simple -- it's essentially one giant pixel, after all, which might not sound exciting when you have millions of them on a dense display surface. But that LED light is something you can use as a signal for alarms, or to tell you that you have a message from one app while another is at full-screen, or practically anything else that you can devise software to notice and react to. I get the sense that Juskevicius would prefer that people get the kit version, to help spur interest in actually soldering some hardware rather than just plugging it in. If you're allergic to paying in other than U.S. dollars, the BlinkStick is also available from Adafruit Industries. Watch the video below to see it in action.

First time accepted submitter wick3t writes "The Neo900 fundraising campaign has already achieved the milestone of 200 pre-orders which means that mass production is now feasible. This follows a successful first prototype that was showcased at the OpenPhoenux-Hard-Software-Workshop 2013. Their next target is 1000 pre-orders as they aspire to reduce the production costs of each device." For those not familiar, the Neo 900 is an offshoot of the OpenMoko GTA04 designed for use in the popular Nokia N900 case (and, yes, they're fixing the weak usb port).

Zothecula writes "Last August, it looked as if NASA's Kepler space telescope was as good as scrap due to the failure of its attitude control system. Now the space agency proposes what it calls the K2 mission concept, which may fix the problem by using the Sun to regain attitude control and allow Kepler to resume its search for extrasolar planets."
