The MOSS modular robot system is sort of like LEGO Mindstorms, in that you assemble small blocks to make custom robots and other items. But it has some interesting tricks of its own, as product demonstrator John Moyes shows Timothy Lord at CES 2014. The MOSS kits include lots of little metal balls, so they carry a warning that says MOSS kits are suitable for ages 8 and up, while the company's older Cubelets product, which doesn't have the little balls, is supposed to be okay for ages 4 and up. There is no upper age limit specified for either product, so you're probably safe if you want to buy (and can *afford* to buy) any of these interesting toys.

3-D printing is far from new, but a $499 3-D printer is new enough to get a bunch of people to write about it, including someone whose headline read, CES 2014: Could 3D printing change the world? XYZPrinting, the company behind the da Vinci 1.0 printer, has some happy-looking executives in the wake of CES. They won an award, and their booth got lots of attention. This is what trade shows are all about for small and/or new companies. Now the XYZprinting people can go home and pump out some product -- assuming they got a lot of orders (and not just attention) at CES.

It looks like an ordinary electric guitar, except for a little LED screen on its body and blinking lights up and down the fretboard that show you where your fingers should go. But the gTar, besides being "The First Guitar That Anybody Can Play," hooks to your iPhone. The gTar app includes "...a variety of classical guitar pieces, modern rock, pop, and everything in between." The gTar Kickstarter campaign in 2012 raised $353,392 even though it only asked for $100,000. The company that makes the gTar, Incident Technologies, started in a garage in Cupertino (Silicon Valley) and is now located in San Francisco after several moves caused by the company's rapid growth. On their Support page they say, "We don't have a brick-and-mortar location for you to try the gTar yet, but we're working on it. In the meantime, check us out at events like Maker Faire, TechCrunch Disrupt, and many others."

This is a slightly puzzling product. To begin with, Christopher Goggin, shown as the inventor of the Electronic Dog Nose (as featured in Popular Science) may not be the actual inventor, at least according to some of the comments attached to that 2011 Popular Science article. Yet other comments on the same article claim that the unit Goggin supposedly ripped off is totally different from his, and doesn't work, while his does. A report (pdf) on bed-bugs.co.uk says the device "...clearly fails to perform to the manufacturers specification and procedures." Goggin's badge at CES showed his company affiliation as Datt Solutions Group, but Datt's website did not mention him as of Jan. 21, 2013, several weeks after CES 2014 closed. A New York Real Estate blog is skeptical, as are others. Goggin also claims to have a laser device that will kill the bedbugs you find. It sounds great. But a person who prefers the tried and true to new products that may or may not work might want to use old-fashioned, all-natural Diatomaceous earth, which kills not only bedbugs but other insect pests, and costs very little compared to most other methods. If that method doesn't work, then it may be time to try dogs, lasers, and other ways to find and kill bedbugs, which have been spotted everywhere from luxury hotels to housing projects, even in taxicabs and movie theaters.

According to the company's website, "HAL© is the future of television and media management. Using proprietary gesture and voice control technology..." In this case, HAL© stands for “Human Algorithm LTE.” It looks like it's a lot safer than the original HAL 9000, anyway. Is it ready for prime time? If their CES demo is any indication, not quite. They say HAL© is going to ship in the fall of 2014. The technology? They won't say beyond, "It's proprietary." Ah! Then it must be good, right? Another voice-operated remote control -- that's already available for purchase from major retailers -- is the Ivee Sleek. There are other HALs out there, too. Like this one. And this one, which is a home automation server that costs $2499.00 (& up). Anyway, the retail price for HAL(circle-C) is supposed to be $199 when it hits the streets. And even though it doesn't look like HAL© can do much that I can't already do with my Android phone, Skyvi, and a Chromecast, it might be fun to test and review once it's in production.

A number of companies are either selling or preparing to sell 3-D scanners. Aside from fun (but interesting) uses, like duplicating chess pieces or possibly reproducing a miniature of Rodin's famous sculpture, Fallen Caryatid Carrying Her Stone, Matterform anticipates archeologists reproducing artifacts so that students can study them without handling the precious originals. This video is an interview with Matterform co-founder Drew Cox, who was exhibiting Matterform's scanner at CES 2014. MakerBot is also selling a scanner, as are a growing number of others. In fact, even though Matterform talks about being a low-cost (pre-order price $579) scanner for home use, as opposed to a commercial one that costs thousands. There are also several interesting hand-held scanners out there. Sense sells theirs for $399. Structure has one for $349 that's essentially a peripheral for an iPad. And this is just a random selection from a brief Google search. Use "3-D Scanner" as your search term and you'll find multiple Google pages full of 3-D scanners and information about them -- including software being developed at ETH zurich that turns your smartphone into a 3-D scanner.

In a town called Portsmouth, Ohio, a company called Yost Engineering (YEI) Technology has quietly been making motion sensing devices for military, aerospace, industrial, robotics, and other commercial motion capture uses, including rotoscoping for the film/video industry. Now they want to bring this same technology to gaming. They tried a Kickstarter campaign in 2013, but only got a little less than 1/2 of their target amount pledged. They're going to do Kickstarter again, starting Feb. 14, 2014 -- and this time, they've been working on PR before asking for money. You can see what they're up to in gaming sensor development at www.priovr.com/. Or go to the main YEI Technology corporate site, which has a whole bunch of free downloads in addition to the usual product blurbs.

Bennett Haselton writes "Google created controversy by announcing that Google+ users will now be able to send email to Gmail users even without having those Gmail users' email addresses. I think this debate misses the point, because it's unlikely to create a deluge of unsolicited email to Gmail users, as long as Google can throttle outgoing messages from Google+ users and terminate abusive accounts. The real controversy should be over the fact that Google+ users can search a public database of the names of all Gmail users in the first place. And limiting the ability of Google+ users to write to those Gmail accounts, won't do anything to address that." Read below to see what Bennett has to say.

Shai Goitein started with a powered paper airplane, the PowerUp 1, which was pretty cool. But he didn't stop there. The PowerUp 3 is a powered paper airplane you control with your smartphone. He calls this "a mixture of origami and technology." He also says it's a great toy, class project or whatever for the younger set, since kids start making paper airplanes at the age of six or seven. Adults? Why not? This is obviously a suitable toy for anyone with a two-digit (or three-digit) age number. And PowerUp 3.0 is a Kickstarter-funded project, with (at this writing) $928,091 pledged -- against a $50,000 goal, with another 15 days of Kickstarter funding left to go. There's also a smartphone-controlled PowerUp paper boat kit. Unlike the PowerUp airplane kits, it's not sold out (at this writing). Yet.

The device that does this is the Geonaute 360 Degree Camera. The Geonaute display caught Tim Lord's eye at CES, and he got Geonauter (is that a word?) Marian Le Calves to show him the company's "action camera," which costs $499 -- or more accurately, will cost $499 when it starts shipping. Until then, you can pre-order. Or you could buy a GoPro camera for as little as $199. Geonaute has a bunch of videos on YouTube, some of which are quite fetching. But GoPo has a bunch of slick YouTube videos, too, and at this point they're the dominant brand in the action camera market niche. Will Geonaute be able to capture a decent market share with their 360 degree coolness -- and higher price? Or will they, GoPro, and other action camera vendors get into a price war so that every kid who has a skateboard can make good-looking videos?

Lauro Ojeda is a researcher at the University of Michigan who also works with a Korean company, Microinfinity, that says it works with everything "from basic sensors to full navigation systems, and is becoming the world leading navigation system company." Prof. Ojeda also has a personal website, robotnav.com, where he posts his navigation and control code (under an open source license, of course) that you are welcome to download, play with, install on any suitable device you have handy, and modify at will. A lot of his work is with Lego-based robots because they're both inexpensive and readily available almost anywhere. If you already have a good-sized Lego collection, you probably only need a few pieces to follow or even surpass Prof. Ojeda's work. And who knows? If you manage to make an autonomous Lego robot, your next stage may be a car that drives itself so you can watch SyFy reruns on your way to work instead of worrying about the truck in the left lane that looks like it's about to make a right turn.

The annual Consumer Electronics Show (CES) in Las Vegas is the largest electronics show in the U.S. these days. It's so big that small companies easily get lost among the industry giants and their huge, noisy show floor displays. But there is a press-only 'pre-show' called CES Unveiled that gives visibility to companies that don't have 20' tall displays full of celebrity shills and other razzmatazz. So, in hopes of finding some products more interesting than the inevitable CES "Oh, look! Our latest TVs are 2" wider than last year's models!" blather over incremental improvements to existing products, Tim Lord went to CES Unveiled -- and found a few products that were not repeats from previous years. Good products? Useful? Maybe, maybe not. You decide.

Emmett has a good rep as a video game music composer, and he's worked on a number of Star Trek-related projects, including the recently-released audio book, How to Speak Klingon: Essential Phrases for the Intergalactic Traveler. Emmett freely admits that he has no experience with RPG games. The closest he's come was running a major D&D meetup some years back. But he has experience and contacts developed from many years working online not only within the Star Trek community but (years ago) on Slashdot and as editor for Linux.com. And, he says, when he was a teenager he ran comic book stores. So is Emmett suited to run an RPG company? Possibly. He's actively looking for games to publish. Sales aren't going to start for six months or so, so there is no website for Arrakeen Tactical quite yet. Until there is one, you can contact Emmett about his game venture by emailing angelaATclockworkjetpack.com.

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.

Wayne Rash has covered IT as a reporter and editor for over 35 years. NPR, Fox Business News, and NBC all call on him as a technology expert. A few weeks ago he had an article on eWeek titled How Target's Credit Card Security Breach Could Have Been Avoided. In this video, Wayne tells how you (or your business) can avoid being targeted by miscreants out to steal credit card data. It turns out that the security measures he advocates for businesses are common in other parts of the world but haven't hit the United States quite yet. But don't despair. There are things you can do right now, as an individual, to limit your potential losses from card number thefts. Still, the long-term fixes to the security vulnerability that bit Target need to be made by merchants and card issuers, some of whom are already transitioning to cards and card readers that use EMV chips, and some of whom aren't quite there yet -- but might speed up their efforts after seeing what happened to Target.

Maybe, maybe not. It depends on the application and the user. We're seeing tablets advertised like crazy these days, and a trip to any busy coffee shop with free wi-fi will make it obvious that while there may not be as many tablets in use as notebooks, you see a lot more of them than you did five years ago, when it seemed like Bill Gates was the only person who had one, which he tried to show off as often as he could. In 2010, Apple debuted the iPad, and before long tablets were all over the place. So, on behalf of people we know -- and there are more than a few -- who either sneer at tablet computers or aren't sure they need one, we turned to David Needle, editor of TabTimes.com, for advice on what kind of tablet to buy -- assuming we need to buy one at all.

Last week you had a chance to ask "Chairman Bruce" about the state of sci-fi, dystopian futures, and the modern surveillance state. Below you'll find his answers to those questions, including who would win if he fought William Gibson and Neal Stephenson in a no-holds-barred battle.

The Virtuix Omni "is an omnidirectional treadmill video game peripheral for virtual reality games currently in development by Virtuix," says Wikipedia. With this device and an Oculus Rift, Razer Hydra or a similar "immersive" headset, you can play games equipped to use these devices with your whole body moving in any direction you choose. If you think you saw this product on the Shark Tank TV show or a pitch for it at Kickstarter.com, you're right. You did. The Virtuix Omni people have been pushing their product hard, everywhere they can. Tim ran into their product manager, Colton Jacobs, at the recent AppsWorld conference in London. This video is Tim's record of their conversation.

One of the founders of the cyberpunk genre, Bruce Sterling needs little introduction to science fiction fans. You can read what "Chairman Bruce" has to say at Beyond the Beyond on Wired and the Sterling tumblr. He has agreed to to sit down and answer any questions you may have. As usual, ask as many as you'd like, but please, one question per post.

Preston Gralla hasn't really been following Microsoft since 1820, but he's been doing it so long that it sometimes seems as if he has. His popular Seeing Through Windows blog on Computerworld.com or possibly his IT World blog, The Power of One, may be the main reasons his name is familiar to a lot of people, but he's also written an amazing stack of IT-related books. Obviously, if you look at the lists of blog posts and books Preston has written, he writes about plenty besides Microsoft, and isn't particularly pro-Microsoft. In fact, when we asked him for tablet-buying advice, he recommended iOS tablets if you have plenty of budget, and maybe an Android tablet (specifically the Nexus 7) if your budget is a little tight. Windows? He didn't recommend Windows at all in this context. (Sorry, Microsoft.)
