NASA Moves Closer to VASIMR Rocket Testing

NASA_VASIMR_AdAstra_Rocket.jpg

Remember that new ion propulsion rocket that could slash the time it takes to travel from Earth to Mars to just 39 days? According to AFP, NASA plans to center its future strategy around MIT scientist Franklin Chang-Diaz’s design, called the Variable Specific Impulse Magnetoplasma Rocket (VASIMR), according to AFP.

We’ve also got some more specifics on how the rocket works. VASIMR uses electricity to transform fuels like hyrodgen, helium, or deuterium into plasma gas, which is then heated to 51.8 million degrees Fanrenheit and sent into tailpipes via magnetic fields, the report said. The rocket will be capable of reaching speeds of 35 miles per second (126,000 miles per hour).
NASA worked on the design along with Ad Astra and Canadian firm Nautel. NASA plans to contract with more private firms as it reels in costs following the Obama Administration’s cuts to its Constellation program, which would have returned humans to the moon by the end of the decade. Chang-Diaz is planning for an orbital deployment by the end of 2013, according to the report, and is already working with private space firms SpaceX and Orbital Science Corporation.

Video: Old Apple Notebooks Modded Into a Snowboard

Reduce, reuse, and, if all else fails, recycle, the old mantra goes. But how exactly can you use reuse a dead laptop? In the video above, two German geeks drilled apart their old Mac notebooks and combined them into a snowboard to take to the slopes. As The Unofficial Apple Weblog notes, this is probably just a viral video to plug some Asus notebooks. But we have to admit it’s mighty entertaining to observe just how awful an “Apple snowboard” would be. It’s a heck of a lot easier to watch than dudes catching MSI notebooks with their butts.

NVIDIA Optimus-equipped ASUS N61JV-X2, N71JV-X1 hit the US

Well, we’d heard the first NVIDIA Optimus-enabled laptops would roll out at the end of the month, and lo and behold, the first NVIDIA Optimus-enabled laptops have rolled out at the end of the month. Right now, those include ASUS’ N61JV-X2 and N71JV-X1 models, which are just the first of five laptops that will be available from the company, and each of which cost the same $900. That’ll get you a 16-inch screen and Core i5-430M processor on the N61JV-X2, or a 17.3-inch screen and a Core i3-350M processor on the N71JV-X1, along with the same switchable GeForce GT 325M graphics, 4GB of RAM, and 500GB hard drive on each of them. Still unclear on what NVIDIA has brought to the table with Optimus? Check out our hands-on for some more details and a few benchmarks.

The Conclusion to the Faulty iMac Saga: The Beginning of the Fix [Apple]

The latest iMac was released 16 weeks ago. Since then, it’s been plagued with problems, most notably flickering and/or yellow screens. Today, the saga comes to an end because Apple has acknowledged the issues and offered their support.

At long last, Apple has released a statement to us, admitting the production issues with iMacs—which reader and forum anecdotes imply to be a bit less frequent than before but still very much present at some level—and labeling AppleCare as the proper channel for related complaints.

Apple’s Official Statement

“We’ve addressed the issues that caused display flickering and yellow tint. Customers concerned that their iMac is affected should contact AppleCare.”

These two short sentences might not look like much, but the statement is Apple’s first open acknowledgment of the jaundiced screen issue, and it identifies the problem as one worthy of AppleCare solutions. (A previous statement made to Bloomberg generalized the problem to all LCDs.)

From the start of these iMac updates, I made a deal that “…if Apple can come forward and openly admit the mistake while providing an adequate solution to their customers, I’ll laud them as an example as to how companies can take an unforeseen manufacturing issue and make things right.”

Today, Apple met the terms of that deal, and so will we.

The Catch

Of course, just because Apple has “addressed” these iMac issues doesn’t mean they have completely ferreted out the problems. (Their diction leaves some room for interpretation.). Since the production halt a few weeks back, Apple’s forums seem a little quieter regarding yellow screens, and flickering had already been solved by a firmware update. Still, about 20 people have written us since the production restart—some of them now on their third+ iMac—encountering new iMacs with yellow displays (versus just a handful offering the all clear). That response is slightly more positive than it was in the past, when basically everyone who wrote me complained of flickering screens, yellow screens and a number of other maladies.

Unfortunately, we tried to reconnect with every person who’d written us after suffering through multiple returns, but very few responded either way. My guess is that some had their issues dealt with, while others just gave up on the iMac altogether. Sitting on a few grand for a few months isn’t an easy thing to do for most people in this economy.

Yes, it’s a downright shame that Apple hasn’t been able to completely eliminate the yellow screen issue from the iMac line, whether their yield is 99.9% or somewhere far lower. At this point in time, I don’t think that every iMac shipping is inflicted with a dealbreaker of a screen (which honestly seemed to be the case for a bit in late 2009/early 2010), but I don’t think that nearly every iMac is shipping perfectly, either.

Yields have gotten better. How much better? I honestly don’t know.
(This photo is a yellow-screened 27-inch iMac produced after the production restart—displayed file dates are from an older Time Machine restore.)

As consumers, should we really be content with Apple’s response when evidence shows the problem isn’t entirely fixed? That decision is yours. But I will say, even with constant pressure from a website such as Gizmodo (along with many other publications that, thankfully, jumped on the bandwagon), a fundamental principle holds true: The longer you tell a lie, even one of omission, the harder it is to tell the truth. For Apple to come clean after 16 weeks of shipping an “ultimate display” that isn’t so ultimate should be something that the public can embrace, at least in part.

Because fanboyism and flame wars aside, if we leave no incentive for companies to be forthright regarding their mistakes, why the heck would they?

So Is It Finally Safe To Buy An iMac?

Yup, but with one huge caveat: You should run this test upon receipt. If any part of that screen doesn’t match to your liking, you may very well still need to return your first iMac before getting a system that works as advertised.

Luckily, Apple has acknowledged the issue and thereby removed some of the risk from you, meaning, at the very least, customer service will take your problem seriously. And hopefully, the next time Apple or any other company ships a new product, they’ll notify us of the problems instead of vice versa.

Qisda QD060B00 e-reader hits the FCC

We’ve already seen MIDs, high-res phones, and a few other odd devices from Qisda since it spun off from / encompassed BenQ, and it looks like it’s now trying its hand at another e-reader as well. Still no official word about this one, but the device does look like it’ll hold its own with a 6-inch capacitive touchscreen (16 levels of gray), along with built-in WiFi, a microSD card slot for expansion, and support for all the basic formats you’d expect (including ePub and PDF) — the e-reader itself is also Linux-based. Coming from Qisda, it’s also possible that this one will be picked up by someone else and rebadged before its released, although there’s no indication of that just yet. There are plenty more pics (both internal and external) to be found at the link below, however, along with the device’s user manual.

HUMAVIPS project could lead to humanoids with social skills, humans being tricked

You don’t think the Robot Apocalypse is upon us, but we assure you, it is. The HUMAVIPS project, which will span three years and hopefully result in robots being developed with “social skills,” may seem innocent — even beneficial — at first blush, but let’s think about it. Will “humanoids with auditory and visual abilities in populated spaces” have more power than you, as an Earthling, would like? If all goes well, these robotic dudes and dudettes will be able to mimic what’s known as the “cocktail party effect,” which is better explained as “the human ability to focus attention on just one person in the midst of other people, voices and background noise.” So yeah, this definitely goes two ways — on one hand, you could finally have a live-in robot that pays attention to your feelings as the world around you crumbles, but on the other, these guys won’t have any issue overlooking your wailing when it’s them bringing everything down. Yikes.

AV Receiver Battlemodo: $600 or Bust [Review]

You want a serious home theater. One that will rattle the windows, and ensure movie night is always at your house. But you don’t want to spend more than $600 on the thing that ties it together. Cuz you’re smart.

You’ve got the big screen flat panel, you’ve thrown that cheap HTIB system in the garbage, and you’ve picked out an awesome speaker system. You just need one more component to tie it all together: a surround receiver with enough muscle for Aliens vs. Transformers, and enough ports to handle your Blu-ray player, Xbox and/or PS3, and all of the other black boxes in your living room.

Spending $500 to $600 will get you a receiver that will use a microphone to listen to itself, configuring and equalizing up to seven speakers and a subwoofer. It will switch between at least four HDMI sources and a lot more analog devices, and send everything off to the TV upconverted to HD resolution through a single HDMI cable. The feature sets of competing models are so similar that it can be tough to tell them apart, so I called in the four best in this price range—from Denon, Onkyo, Pioneer and Yamaha—to help you make your decision. As it turns out, the decision was easy.

A side note, before we continue: None of the tested receivers—and no receiver currently shipping—features the HDMI 1.4 required to pass 3D video signal to a 3D TV. If 3D is a must-have feature for you, you’ll have to stay tuned, as all of the major electronics makers announce and eventually ship their 2010 models. But a new crop of models may actually mean better deals on the receivers reviewed here, and don’t forget, even if you’re a big enough spender to get a first-gen 3D TV, you can always route video directly from 3D Blu-ray player to 3D TV, using the receiver for audio alone.

I tested each model in my 7.1 channel theater—a $5300 Mirage OM Design system which has the resolving power to highlight minute differences in sound between amplifiers. This also gave me the chance to test each model’s two-channel music and multi-channel film soundtrack performance against my reference Pioneer Elite 49TXi—Pioneer’s $4500 flagship from 2005—a yardstick to hold up in order to see how far mid-priced receivers have come since then.

In addition to sonic prowess, I also judged each model in the areas of design and build quality, ease of use, and video conversion/scaling ability. Here are the full results of my tests:


The Onkyo, with superior sound quality and a multitude of HDMI inputs, put up a very tough fight against the Pioneer. But ultimately the Pioneer’s class-leading user interface, superb auto calibration system and built-in USB and iPod/iPhone support gave it the win.

Pioneer VSX-1019AH-K: First Place


At first I wasn’t sold. The Pioneer’s music performance without EQ engaged was disappointingly dull and flat. Switching on EQ really kicked the amp into life, though, bringing detail and staging into proper focus. I found that the default curve was overemphasizing the upper midrange and treble, but fortunately the 9-band EQ is user configurable, and with a few adjustments I was able to dial in a nicely balanced sound that was fairly close to my reference, save for a persistent artificial coloration in the mids and highs. The Pioneer includes a technology called “Advanced Sound Retriever” which claims to restore compressed music files to near CD quality. (It may not surprise you that the others also feature similar abilities.) To test this, I loaded an iPod Touch with tracks encoded at moderate bitrates. ASR definitely did its job, as every track I tried sounded significantly more lifelike and enjoyable with ASR engaged. I connected the iPod to my more expensive reference system with a mini-jack cable and felt it still had the edge, but ASR made the difference between $4500 receiver and $500 receiver considerably smaller.

Movie audio performance with EQ was very good, with realistic portrayals of the cannons in Master and Commander and the drum sequence in House of Flying Daggers. Analog video scaling from my DVE test disc was decent, though the Pioneer struggled a bit in the jaggies test.

The VSX-1019AH-K is $100 less than the model that it replaced, and it appears that Pioneer was able to hit the $499 price point by chopping out 10 lbs. of power supply and much of the multi-channel analog connectivity. From bench tests that I’ve seen, being the shortest and lightest of the group has not affected the Pioneer’s ability to compete in terms of horsepower. While it can no longer serve as a surround preamp—the Yamaha is the only one of this group that can—the Pioneer’s user interface is simply in a different class than the competition at this level. Combine that with the forward thinking built-in USB and iPhone connectivity, and you’ve got a winner.

Onkyo TX-SR607: Second Place


The Onkyo loses in the looks department with its blocky styling and ancient pale green display, but give it some music to play and things turn around rather quickly. Without EQ engaged, the Onkyo produced the best, most transparent sound of the group, with realistic soundstaging and natural timbre that was surprisingly close to my reference. Switching on EQ mostly made everything sound artificially forward and aggressive, so I left it off for the majority of my music listening. Onkyo’s “Music Optimizer” with the iPod just about equaled my reference, which shows just how effective this technology is.

The Onkyo also did very well with movie sound, though without EQ the bottom end was not quite as strong and impactful as the Pioneer in the cannon and drum sequences. Only five bands are available in the EQ, but this was enough to improve the bass response for action sequences without throwing off the rest of the range. I tested several movies in both the Onkyo-exclusive Dolby Pro-Logic IIz “height speakers” mode and with my speakers in their regular back surround configuration. (The Onkyo is not a 9.1 receiver, so your choice is either one or the other.) I preferred the standard configuration, as I mostly couldn’t tell whether the height speakers were even on. A few weather effects perhaps sounded slightly more realistic, but I certainly wouldn’t go to the trouble of permanently mounting and wiring extra speakers high on the front wall for a bit of rain or wind.

The Onkyo firmly embraces digital audio and video with a total of six HDMI inputs, and completely ignores multi-channel analog connectivity. Analog video scaling was by far the weakest of the group, with poor results in DVE’s resolution, jaggies, and 2:3 pull-down tests. The front panel HDMI input is great, but the Onkyo really needs a USB port and a full GUI to put it over the top.

Denon AVR-1910: Third Place


The Denon’s performance with music was solid, besting the Pioneer but not quite matching the Onkyo. Without EQ its sound was a bit leaner than the Onkyo’s and slightly dry, with mids lacking a bit in body and warmth. As with the Onkyo, the default EQ curve just pumped everything up without any finesse. The Denon offers nine bands of EQ to play with, and by applying much more mild adjustments than the default curve, I was able to achieve a sound close to the Onkyo’s un-EQed performance. As with the Pioneer and Onkyo, Denon’s “Compressed Audio Restorer” significantly improved its performance with the iPod, though not enough to best the Onkyo or my reference.

Movie performance let the Denon down a bit. The cannons in Master and Commander had a distinct lack of impact compared with the Pioneer, even with EQ engaged, and the Flying Daggers drum sequence sounded a bit flat, particularly when I turned off the subwoofer and let the main channels run full range. Things picked up for the Denon with analog video scaling, where it aced all of my DVE tests.

The Denon was the most stylish of the group, but the plastic front panel and controls did not have the precision and quality feel of the others. The front panel display was also the smallest and hardest to read from across the room. The Denon’s biggest problem though is that it just doesn’t seem to have changed much compared to its predecessor, the AVR-1909. One more HDMI input and one less component video input seem to be the extent of the major changes. The user interface is functional, but still looks 15 years old. With the Pioneer now offering a full GUI at the $500 level, Denon needs to do the same.

Yamaha RX-V765: Fourth Place


Music from the Yamaha sounded much like Denon without EQ. It titled quite a bit towards the lean and dry side, with forward and slightly grainy highs that became tiring at higher volume levels. Two EQ curves are available, and the “natural” curve was able to tame some of the excessive brightness. I also tried adjusting the 7-band EQ, but I was never able to get the Yamaha to sound as good as the Onkyo or Denon.

Yamaha’s “Compressed Music Enhancer” brought similar improvements from the iPod as the other receivers, but couldn’t overcome the Yamaha’s inherent weaknesses with music. It did perform one trick that the others can’t: I was able to stream Last FM from my Nokia via the Bluetooth dock.

The Yamaha fared better with movies. It delivered a realistic amount of punch to the cannon and drum sequences, though I still preferred the Onkyo’s more neutral tonal balance. Analog video scaling performance was average, with poor results in the jaggies and 2:3 pull-down tests.

The Yamaha shares nearly all of its chassis components with the $900 RX-V1065, and due to that its build quality is a considerable notch above the rest of the group. It looks and feels like a $900 receiver, which is why it’s such a shame that the terrible UI completely lets it down. Setting up the Yamaha was aggravating; partly due to the un-assignable inputs, the badly designed remote and the cryptic way that Yamaha labels most functions, but mostly due to the UI. The four “Scene modes” are an attempt to replicate the Activities function of a Harmony remote, but they don’t really work in practice. Unless all of your components are made by Yamaha and support the Scene control ability, pressing a Scene button can do little more than switch the receiver to an input and select a sound mode, which the others can do just as easily with their own source buttons. In the end you’re going to end up using a universal remote anyway, making the Scene abilities completely unnecessary. The optional Bluetooth streaming support is great for many people who use their cellphone as an audio source, but the Yamaha is just too much of an incomplete product to recommend.

And Now For Something Completely Different…


The Onkyo produces surprisingly decent stereo sound for a mid-priced receiver, but what if stereo is all you are interested in? What if you don’t need HDMI switching, or Dolby Pro-Logic IIz, or Audyssey equalization, or any of the other stuff crammed in to a modern receiver? Can you do better for $500? Indeed you can, with something called an integrated amplifier.

Integrated amplifiers are a stereo preamp and amplifier combined into one component, and they offer maximum sound quality for the dollar as they basically only have one function. The NAD C-326BEE and Cambridge Azur 550A integrated amps both cost around $500, and both will outperform any of these receivers in stereo. Since there’s no need to worry about having the latest sound mode or HDMI version number, you can stretch your dollar even further by looking on the secondhand market. A range of $500 to $700 can buy a Musical Fidelity, Primare or Arcam on audio trading sites like Audiogon that will be able to challenge $2500 AV receivers in stereo mode. Add a second hand pair of bookshelf speakers from PSB or Monitor Audio—or maybe even a pair of Magnepan 1.6s if you’re feeling adventurous—and you’ve got truly high-end sound for around $1500.

Shuttle Intros Hide-away Mini PC

ShuttleXS35.jpgThose attending CeBIT next week in Hanover, Germany, will get a first look at the 3.3cm-wide Shuttle Barebone XS35, a mini PC designed to be fitted behind flat panel displays. It ships with Intel’s Atom D510 Dual Core processor (2x 1.66GHz) and the NM10 Express Chipset. More important is the NVIDIA GT218 (ION2) graphics card, crucial for seamless 3D streaming and video playback.

Naturally this media Mini includes an HDMI port, but you’ll also get five USB ports, as well as VGA, LAN, and audio ports. It includes a multi-format card reader, a 2.5-inch hard disk, and an optical slimline drive. While the XS35 will be on display next week, it won’t go on sale until the second quarter of the year. Shuttle hasn’t settled on a price just yet.

Motorola CLIQs falling victim to latest firmware? (updated with official statement)

Haven’t willfully submitted to the CLIQ’s new update yet? Well, you might want to hold off, because it looks like the new code is causing more heartache than good. A variety of reports on T-Mobile’s official support forums echo the same overarching complaint, which is that messaging is a disaster zone ever since version 1.3.18 took hold — long freezes when using the messaging app or widget, messages not getting sent or being sent multiple times — basically all the things you really don’t want to happen on a device that touts its social connectedness. For what it’s worth, we’ve personally seen this happen on a CLIQ since the update, so we know there’s something going on here; T-Mobile says that the complaints have been “forwarded… to the appropriate people,” so hopefully we’ll see some resolution soon. In the meantime, users experiencing issues are advised to not perform a master reset — important advice, considering that’s one of the first fixes many users might entertain.

Update: Follow the break for the full details from Motorola — it looks like a date issue where the year gets stuck on 1969 is priority one for them, but they’ve got a workaround set up until a new OTA update’s ready. Messaging issues may be alleviated by clearing out your backlogs — if you’ve got too many old messages, it sounds like this could be bogging things down.
