New submitter Otis_INF writes "To honor Alan Turing, two researchers at the CWI built a simple LEGO Turing Machine, to show everyone how simple a computer actually is. Primary goals were to make every operation as visible as possible and to make it using just a single LEGO MINDSTORMS NXT set." And if a simple Turing machine gets old, Reader miller60 adds a link to this Lego data center "that recreates all the major features of an IT facility, assembled from 5,772 pieces, 28 figures, and 1 meter of fiber optic cable. The builder, Tanaka, has uploaded details to the Lego Digital Designer Gallery so others can build and adapt their own."

Last week you got a chance to ask the team behind Space Command about their project and all things sci-fi. Marc Zicree, Doug Drexler, David Raiklen, and Neil Johnson were nice enough to put down the blasters and answer a handful of your best questions. David even answered one of his own! Read below to see what they had to say.

ozmanjusri writes with this story from PC World: "A company that makes keyboard docks has announced a laptop-like peripheral that uses smartphones for processing and storage. Since many Android and Apple phones have multi-core processors powerful enough to deliver laptop-level performance, they only lack usable screens and keyboards to be productive for most office work. ClamCase believes their 13.3-inch 1,280 x 720 ClamBook with keyboard, multi-touch touchpad, and dedicated Android keys will make up for the lack, and turn smartphones into fully-functional laptops. A device like the ClamBook could be a real game-changer for the computer industry. If it succeeds, peripheral makers could build docks which would allow any monitor, keyboard, mouse and storage to be powered by any Android phone. It's a combination which would make BYOD offices very tempting for the corporations who are the Windows/Office combination's remaining cash-cow." I only wish the company would license the idea as well to established makers, so otherwise conventional laptops could gain the ability to easily become advanced phone screens, too.

OceanMan7 writes "My 7-year-old son is getting very interested in microscopic things — from bacteria to parameciums (paramecia?) Not being a biologist, I would appreciate advice on what type of microscope to get. I'd be operating it and he viewing with supervision. I'd like something better than a toy and plan to buy it used, if possible. Extra points if it's stereo and also allows me to view opaque objects at low magnification."

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!"

hypnosec writes "With the wide array of electronic devices available in our everyday lives, it appears that children have formed an attachment to a different kind of toy. According to the latest survey, 77 per cent of polled US, UK parents believe that iPads and other tablets are good educational tools that boost kids' creativity. Meanwhile, researchers in this field explain that it is a matter of balance — and a child's access to tablets and other similar electronic devices should be monitored. Specialists warn that using tablets in excess could cause attention deficit disorder and even autism, particularly at a very young age."

Fluffeh writes "A nice summary at TechDirt brings word that Bruce Schneier has been debating Kip Hawley, former boss of the TSA, over at the Economist. Bruce has been providing facts, analysis and some amazing statistics throughout the debate, and it makes for very educational reading. Because of the format, the former TSA administrator is compelled to respond. Quoting: 'He wants us to trust that a 400-ml bottle of liquid is dangerous, but transferring it to four 100-ml bottles magically makes it safe. He wants us to trust that the butter knives given to first-class passengers are nevertheless too dangerous to be taken through a security checkpoint. He wants us to trust that there's a reason to confiscate a cupcake (Las Vegas), a 3-inch plastic toy gun (London Gatwick), a purse with an embroidered gun on it (Norfolk, VA), a T-shirt with a picture of a gun on it (London Heathrow) and a plastic lightsaber that's really a flashlight with a long cone on top (Dallas/Fort Worth).""

mikejuk writes "Kurt Grandis took some cutting edge and open source AI tools, Python, an Arduino and a SuperSoaker and built the (almost) perfect squirrel hosing machine. The project involved Open Computer Vision (OpenCV), an a SVM learning procedure that he trained to tell the difference between a squirrel and a non-squirrel. After 'perfecting' the classifier the hardware came next — a SuperSoaker Mark I was used as the 'water cannon.' A pair of servos were used to aim the gun and a third to pull the trigger."

The L.A. Times reports that 12-year-old Arturo Valdenegro's winning entry in a paper-airplane contest got upscaled to slightly larger dimensions, courtesy of Pima Air & Space Museum's Giant Paper Airplane Project, and flown, via helicopter assistance, in the Arizona desert. Slightly larger, in this case, means the plane based on Valdenegro's designs "was 45 feet long with a 24-foot wingspan and weighed in at a whopping 800 pounds," constructed of a tough, corrugated material called falcon board. Unfortunately, the tow didn't take the plane as high as planned (only 2,703 feet, instead of four or five thousand) so the resulting flight was brief and destructive — which doesn't make the accompanying launch video any less fun to watch, though I wish it showed more of the flight, including its end. (I tend to always make the same kind of acrobatic glider; do you have any good paper-airplane hints?)

dangle writes "F.A.T. Lab and Sy-Lab have officially released their Free Universal Construction Kit, allowing builders to freely interconnect parts from Lego, K'Nex, Fischertechnik, and other common building sets. ZomeTool and Zoob patterns will be available after related patents expire. The makers have also spent considerable effort investigating and anticipating legal complaints from manufacturers, using an Inverse Think of The Children Argument: Some may express concern that the Free Universal Construction Kit infringes such corporate prerogatives as copyright, design right, trade dress, trademarks or patents of the supported toy systems. We encourage those eager to enforce these rights to please think of the children — and we assert that the home printing of the Free Universal Construction Kit constitutes protected fair use." Model files are available over at Thingiverse. The designs are all covered by the CC BY-SA 3.0.

JohnGrahamCumming writes "In this simple project, a hacked Linksys WRT54GL talks to a public API to get real-time bus information, and displays the times of the next buses on a model bus. Never miss the bus again! 'It's possible to reflash the Linksys with a custom Linux installation that lets me control the box completely (and still use it as a wireless router). There are various project, but I used OpenWRT. With OpenWRT it's possible to SSH into the box and treat it as any Linux server (albeit a rather slow one). But there's plenty of power to grab bus times and update an LED display connected to the WRT54GL's serial port. "

An anonymous reader writes "Scientists at Cambridge University have used Lego Mindstorms robots to create an artificial bone-like substance. The toy robots proved to be much easier to set up and vastly more economical than more high-tech solutions. Their research is featured in a video for the 2012 Google Science Fair."

Phurge pointed out a story about a man with a fleet of remote control toys and a lot of patience. "Excavating a basement using professional machinery is nothing new but doing it with radio controlled (RC) scaled models is something unheard of. Welcome to the little big world of Joe, from Saskatchewan, Canada. For the past 7 years, Joe has been digging out his basement at an average annual rate of 8 to 9 cubic feet using nothing more than RC tractors and trucks. And we're talking about the whole nine yards here — he starts by transporting the excavator on an RC truck to the basement, unloads it, digs and uses other trucks to transfer the dirt up to the ground through a spiral ramp! He even has a miniature rock crusher! 'I feel quite fortunate to have stumbled onto this basement excavation idea, it's been a great past time to date dreaming up new ideas to tackle different projects along the way,' Joe wrote on the Scale4x4rc forums where he also posted pictures and videos of his feat."

HerbieTMac writes "Political science professor Francis Fukuyama builds and flies his own personal surveillance drones. His current model requires ground visibility but he is working on the HAM license that would allow fully remote operation. His YouTube videos (video 1 , video 2) are particularly impressive." I had no idea that Francis Fukuyama had such technical interests.

An anonymous reader writes "Last weekend, during the Nuremberg Toy Fair 2012, I spotted a really cool new system for 'professional' RC models based on Embedded Linux. The WiRC allows you to control an RC car (or any other RC vehicle) with an iOS/Android device using WiFi. The core of this system is a 240 MHz ARM9 processor, with 16 MB SDRAM and 4 MB FLASH (with 2 USB ports and 802.11b/g WiFi, a microphone input and a Speaker output). It features 8+4 channels of output. A free software SDK is now in development to code your own transmitter applications."

First time accepted submitter psiogen writes "Flynn Michael, an instructor at New York Jedi, an organization that teaches 'practical knowledge of how to use a lightsaber, left his custom-crafted blade for only a few imperial minutes, but when he returned, it was gone. From the article:'“Who steals somebody’s lightsaber? It’s like stealing someone’s toy out of the sandbox,” said Michael, the founder of New York Jedi, a stage combat performance group. “I finally got my uber custom saber, and then some jerk walks out with it."'"

mikejuk writes "Quantum computing is currently a major area of research — but is this all a waste of effort? Now Scott Aaronson, a well-known MIT computer scientist, has offered a prize of $100,000 for any proof that quantum computers are impossible: 'I'm now offering a US$100,000 award for a demonstration, convincing to me, that scalable quantum computing is impossible in the physical world.' Notice the two important conditions — 'physical world' and 'scalable.' The proof doesn't have to rule out tiny 'toy' quantum computers, only those that could do any useful work."

mikejuk writes with an excerpt from an article at i-programmer about a neat graphics demo written in Dart: "One of the difficulties in getting a new computer language accepted by a wider audience is that there is doubt that it is real. Is it a toy language that just proves a concept or can it do real work? In the case of Dart, which is Google's replacement for JavaScript, the development is speeding ahead at a rate that is impressive but worrying. To prove that Dart is already a language that can be used, we now have a port of the well known 2D physics engine Box2D, the one Angry Birds uses, to Dart." Box2D has previously been ported to Javascript. Source is available at Google Code (under the Apache license). Note that you'll need Chromium to run the demos.

redletterdave writes "Apple has allegedly threatened to sue Chinese company 'In Icons' over its eerily realistic 12-inch action figure of Steve Jobs, the company's late founder and CEO. The 1:6 scale model, which was said to be distributed by DiD Corp. in late February, comes with the clothes and accessories popularized by Jobs, such as the black faux turtleneck, blue jeans and sneakers. The figurine is packaged in a box that looks like Walter Isaacson's 'Steve Jobs' biography cover, and also comes with a 'One More Thing...' backdrop, as well as two red apples, including one with a bite in it. To make it extra creepy, the doll's realistic head sculpt features Jobs' famous unblinking stare. Apple reportedly wrote 'In Icons', telling the Chinese manufacturer that any toy that resembles Apple's logo or products, or Job's name or appearance, is a 'criminal offense.' Attorneys believe a Steve Jobs action figure released after his death violates the 'right of publicity,' which is a state law that protects one's image, voice, photograph, identity or signature from being used commercially without consent. Furthermore, California's Celebrity Rights Act in 1985 protects a celebrity's personality rights up to 70 years after their death."
