A Build-It-Yourself Electric Vehicle 84

Taco Cowboy writes "Here's yet another exciting project for DIY geeks. Modi-Corp, a Japanese company, has just unveiled a new electric car that you can actually build yourself. Not to be confused with the Toyota 'Prius,' the DIY electric car from Modi-Corp is called 'PIUS.' It's a single-seat electric car that will be released next spring in Japan. The company hopes that the PIUS kits can be used as educational tools, expecting to sell them to universities and mechanical schools with the opportunity to have customizable parts embedded in the EV for testing."

Has the 3-D Hype Bubble Finally Popped? 261

An anonymous reader writes "An article at Time speculates that the recent hype surrounding 3-D display technology has finally peaked and begun to subside. As evidence, they point to comments from Nintendo president Satoru Iwata, who does not seem particularly enthusiastic about it, and concedes it won't be a major selling point if the company continues to have 3-D enabled products in the future. He said, 'So, now we've created the 3DS and 3DS XL and also have some games out there that are really using that 3D effect that we can see, from my point of view, that it's an important element. But as human beings are this kind of surprise effect wears off quickly, and just [having] this 3D stereoscopic effect isn't going to keep people excited.' Revenue from 3-D films is also dropping, and while 3-D television sales are rising, only 14 percent of potential buyers think 3-D is a 'must have' feature."

Putting the Raspberry Pi Into Orbit 82

Jack Spine writes "The Raspberry Pi is likely to be blasted into space, according to project founder Eben Upton. The $35/$25 credit-card-sized single-board educational computer could be used in sounding rockets, satellites, and high altitude balloon tests, according to Upton. Raspberry Pi has proved wildly popular since its launch, with one developer planning to build into a model boat to sail it across the Atlantic."

MIT Develops Holographic, Glasses-Free 3D TV 98

MrSeb writes "Engineers at the Massachusetts Institute of Technology (MIT) are busy working on a type of 3D display capable of presenting a 3D image without eye gear. What you've been presented with at your local cinema (with 3D glasses) or on your Nintendo 3DS console (with your naked eye) pales in comparison to what these guys and gals are trying to develop: a truly immersive 3D experience, not unlike a hologram, that changes perspective as you move around. The project is called High Rank 3D (HR3D). To begin with, HR3D involved a sandwich of two LCD displays, and advanced algorithms for generating top and bottom images that change with varying perspectives. With literally hundreds of perspectives needed to accommodate a moving viewer, maintaining a realistic 3D illusion would require a display with a 1,000Hz refresh rate. To get around this issue, the MIT team introduced a third LCD screen to the mix. This third layer brings the refresh rate requirement down to a much more manageable 360Hz — almost within range of commercially produced LCD panels."

Student Creates World's Fastest Shoe With a Printer 144

An anonymous reader writes "Engineer and designer Luc Fusaro from the Royal College of Art in London has developed a prototype running shoe that can be uniquely sculpted to any athlete's foot. It's as light as a feather too, weighing in at 96 grams. The prototype is aptly named, Designed to Win, and is 3D printed out of nylon polyamide powder, which is a very strong and lightweight material. The manufacturing process uses selective laser sintering (SLS), which fuses powdered materials with a CO2 laser to create an object. This process means 3D scans can be taken of the runner's foot so as to ensure the shoe matches the shape perfectly. Fusaro can also change the stiffness of the soles according to the athlete's physical abilities. The shoe can improve performance by 3.5%, meaning a 10 second 100-meter sprinter could see his time drop by 0.35 seconds, which is a huge time saving relatively speaking. Imagine if Usain Bolt put a pair of these running shoes on."

FishPi: Raspberry Pi Powered Autonomous Boat To Cross the Ocean 136

lukehopewell1 writes "The Raspberry Pi is a triumph in computing, and it's now set to become a triumph in robotics as one developer plans to build a model boat around it and sail it across the Atlantic Ocean, completely unmanned. It's codenamed FishPi and will see a model boat sail across the Atlantic all by itself save for a camera, GPS module, compass and solar panels." The creator is posting updates on the build progress using a forum on his website.

Ask Slashdot: a Good Geek Project For My Arthritic Grandfather? 122

An anonymous reader writes "My grandfather is a retired electrician whom I've been trying to keep mentally busy. Together we've gotten an Arduino kit and have been working on some simple projects. He does the wiring and I've been writing the code. Recently his arthritis has been getting worse and he's been unable to work with the tiny components that the Arduino projects require. Does anyone have a recommendation for something similar we could work on together that would be easier for someone with his compromised manual dexterity?"

12-Core ARM Cluster Beats Intel Atom, AMD Fusion 105

An anonymous reader writes "Phoronix constructed a low-cost, low-power 12-core ARM cluster running Ubuntu 12.04 LTS and made out of six PandaBoard ES OMAP4460 dual-core ARMv7 Cortex A9 chips. Their results show the ARM hardware is able to outperform Intel Atom and AMD Fusion processors in performance-per-Watt, except it sharply loses out to the latest-generation Intel Ivy Bridge processors." This cluster offers a commendable re-use of kitchenware. Also, this is a good opportunity to recommend your favorite de-bursting tools for articles spread over too many pages.

Speech Recognition Using the Raspberry Pi 74

aonsquared writes "In a previous Slashdot story, I demonstrated a voice-controlled robotic arm using the open-source speech decoder Julius. This time, I have managed to port the system to a Raspberry Pi to control the same robotic arm, and as usual, posted the tutorial and source code. Some negative reviews of the Raspberry Pi are starting to appear, and they're missing the educational point of this device — I'm hoping this will counter the naysayers, and help inspire a new generation of hackers, as well as also bring open-source speech recognition the same attention as proprietary solutions (i.e Siri) are getting!"

Intel Ivy Bridge Processor Hits 7GHz Overclock Record 144

MojoKid writes "Renowned Overclocker HiCookie used a Gigabyte Z77X-UD3H motherboard to achieve a fully validated 7.03GHz clock speed on an Intel Core i7 3770K Ivy Bridge processor. As it stands, that's the highest clockspeed for an Ivy Bridge CPU, and it required a steady dose of liquid nitrogen to get there. HiCookie also broke a record for the highest memory speed on an Ivy Bridge platform, pushing his G.Skill Trident X DDR3-2800 memory kit populated in four DIMM slots to 3,280MHz. Not for the faint of heart, the record breaking CPU overclock required that HiCookie pump 1.956V to the processor, according to his CPU-Z screenshot. The CPU multiplier was set at x63."

Ask Slashdot: Hobbyist-Ready LCD Touch Panel For Embedded Projects? 142

michael_cain writes "I've been asked (by family, friends) to consider several small embedded controller projects. A good starting point for all of them would be a backlit LCD graphics module with touch screen pre-mounted in a plastic enclosure with enough room behind the display for a custom circuit board. 320-by-240 pixels, 3.5 to 4.5 inch diagonal measure, monochrome is sufficient (but color is always cool), easily driven by an AVR or PIC type microcontroller. And priced at a reasonable point for a hobbyist! Anyone seen anything like this?"

Ask Slashdot: DIY NAS For a Variety of Legacy Drives? 260

An anonymous reader writes "I have at least 10 assorted hard drives ranging from 100 GB to 3 TB, including external drives, IDE desktop drives, laptop drives, etc. What's the best way to setup a home NAS to utilize all this 'excess' space? And could it be set up with redundancy built-in so a single drive failure would cause no data loss? I don't need anything fancy. Visibility to networked Windows PCs is great; ability to streak to Roku / iPad / Toshiba etc would be great but not necessary. What's the best way to accomplish this goal?"

Sigrok: An Open Source Logic Analyzer 42

Uwe Hermann today announced the availability of sigrok, one of the first Open Source logic analyzers. Tired of being tied to Windows and proprietary software with limited features, in late 2010 he began work on flosslogic, which, after discovering Bert Vermeulen was also working on similar software, became sigrok. From the article: "Thus, the goal was to write a portable, GPL'd, software that can talk to many different logic analyzers via modules/plugins, supports many input/output formats, and many different protocol decoders. ... Currently supported hardware includes: Saleae Logic, CWAV USBee SX, Openbench Logic Sniffer (OLS), ZEROPLUS Logic Cube LAP-C, ASIX Sigma/Sigma2, ChronoVu LA8, and others." Their wiki has a list of supported protocols as well. You can grab the source over at SourceForge.

KegDroid: Combining Arduino, Android, and NFC to Dispense Beer 48

mikejuk writes, quoting I Programmer: "If you are looking for an exciting hardware project, KegDroid deserves a look. It is a sophisticated system that involves Android, Arduino, NFC, plumbing and — beer. Perhaps the final stroke of genius is to package the whole thing in a Droid body. Some how the little green fella looks at home on the bar. You have heard of desktop and laptop apps now we have bartop apps to add to the list" Details are fuzzy currently, but from all appearances this is a repackaged KegBot in a very fancy shell.

Video Video: Paul "Froggy" Schneider's Hard-Won Wisdom For Conference Organizers Screenshot-sm 35

Cleveland-based programmer Paul Schneider, better known both online and in person as Froggy, first organized Notacon after trips to HOPE and other hacker cons gave him the idea; there weren't any gatherings like it in Cleveland at the time, and attending HOPE cost more in money and time than many locals would have been willing to justify for a weekend. Froggy sensed there was a big enough community in Cleveland of hackers, musicians, artists and others to support one, though. So he wrangled space, put out the word, and lined up enough presentations to make it happen. Now, Notacon's been going on for nine years straight (and year 10 is already in the works). In that time, Froggy's developed some thoughts about how to pull off organizing a gathering that involves hundreds of people at a time — and not just any people, but ones with soldering guns, nerf guns, fencing sabers, a lot of electrical equipment, and sometimes (egads!) even children. Froggy is quick to credit the dozens of people — about 20 core staff, and others with smaller but important roles — who also take part in planning and running the conference. Finding hard-working, like-minded souls may be the most universal part of his advice on running a similar event; watch the video interview for more.
