Guy Builds Wind Tunnel-Cooled Computer to Help Cure Cancer

I’ve had problems with computers and video game systems overheating over the years, so I’m all for good cooling systems. And while some computer modders have solved the problem by adding more cooling fans and heat sinks, I think this build might just be a bit more than most of us need.

What you’re looking at here is the Wind Tunnel Computer. It was built by Mike Schropp over at Total Geekdom, and it’s nothing short of awesome, if you ask me. Those giant ducts you see on the left and right are air intakes and outputs for the 6-foot-wide system, which is mounted in a contraction chamber in the middle designed to take full advantage of the increased air speed as it flows through.

The beefy Intel Ivy Bridge 3770k powered system is overclocked to a whopping 4.5GHz, along with overclocked Radeon 7970 GPUs running on Sapphire Dual-X cards. But it doesn’t just run fast, look cool and stay cool – Mike built it for a good cause. It’s connected to the World Community Grid project, and its CPU and GPUs spend their days and night crunching numbers to help cancer researchers find a cure. And thanks to the massive throughput of the system, it’s able to push through about 20x the workload of an average 4-core system. While that’s all awesome, I do wish Mike had actually built a small wind test chamber inside of it for other science experiments. Maybe for version 2.0.

He built the system using large MDF wood panels for the vent sections, and there’s a big box fan installed in one end of it to generate the wind. Mike assembled the main computer section using custom-cut Lexan so you can see through to it, and aluminum pieces to finish the look. It’s even got a control panel on the front with LED temperature gauges and key switches for turning the fans on and off.

Using a wind-speed tester, Mike was able to determine that the inlet takes in air at about 0.6MPH, and the exhaust port pushes out air at 1.4MPH. However, it’s the center contraction section where the computer is that really benefits from the design, where the wind reaches 12MPH – or 9MPH with the computer in place. He actually was able to push wind speeds as high as 26-30MPH with the fan set on a higher setting. He even used smoke testing to ensure optimal airflow over the components.

DIY Silent Computer Doesn’t Make a Peep

I’ve gotten used to my computer rig making lots of noise, when it’s totally quiet, it usually indicates some sort of a hardware failure. Some computers run 24/7 and generate a lot of heat because getting work done. While there are certainly some machines out there that have no fans and are pretty quiet, Redditor DeFex wanted to build a rig that was completely silent, by doing away with fans, and all other moving parts.

His DIY silent computer  features a 65W Intel Core i5 Ivy Bridge processor, so it’s powerful enough to handle all his media center needs. A solid state disk replaces a traditional IDE drive, which gets noisy. SSDs also generate less heat. This system also has no DVD or Blu-ray drive. In order to cool this computer, DeFex picked up a large 10″×7″ heatsink from HeatSinkUSA, which draws away heat from the motherboard.

The case includes some parts that were 3d-printed using a MakerBot 3D. The overall project is pretty cool, though it’s still a work in progress. You can check out more pics of the build over on imgur.

2012 iMac “Assembled in USA”

Just about every device that Apple sells these days is made in China by Foxconn and other major manufacturers. Though it looks like some of Apple’s items are no longer being manufactured in China. A recent teardown performed by iFixit on the new 21.5-inch iMac revealed that the machine was made in the USA.

I say the teardown revealed this fact, but it was actually etched on the back of the iMac’s case, in plain sight. The little laser its stamp on the back says “Assembled in USA.” Exactly how much the machine is actually assembled in the US remains unclear – though the machine’s large IPS display is definitely still assembled in China by LG.

Products can be called “Assembled in the USA” without all components actually being produced within the US. The only qualification is that “substantial” assembly must take place in the US. According to the FTC having all components assembled in foreign countries and merely screwed together in the US wouldn’t qualify product to be labeled as “Assembled in the USA,” so Apple must have a manufacturing facility or partner somewhere in the US once again.

Regardless of where the new iMac is made, the iFixit teardown also revealed that the slim new model is almost impossible to repair or upgrade, so if you want an iMac that you can tinker with, then grab a 2011 model.

PC makers: It’s not our fault people don’t care about Windows 8

Microsoft has been bragging about the sales figures for Windows 8 touting 40 million licenses sold. Microsoft has also bragged that Windows 8 upgrades have outpaced Windows 7 upgrades. However, rumors are circulating that internally Microsoft is unhappy with the rate at which consumers are adopting Windows 8.

According to the rumor, Microsoft is unhappy with the adoption rate and Windows 8 sales haven’t met Microsoft’s internal projections. The source of the rumor also claims that Microsoft is blaming computer makers and their “inability to deliver” compelling hardware. Wired reports that computer makers are saying that it’s not their fault Windows 8 isn’t selling better.

Wired reports that the consensus among computer makers that it spoke with is that Windows 8 devices are meeting or almost meeting sales projections. One OEM also noted that it had lower expectations for Windows 8 than previous launches because the field is more crowded. Toshiba America’s PC and TV business VP Jeff Barney said that Windows 8 device sales were “going as predicted.”

Barney also noted that it sounds as if Microsoft may have been more optimistic with sales predictions. Computer manufacturers expect the momentum of Windows 8 to continue to grow throughout 2013. Many manufacturers also say that consumers should expect more touch-focused devices running Windows 8 as computer makers attempt to fight tablets on more even footing.

Raspberry Pi’s $25 Model A enters production, could be in tinkerers’ projects early next year

Raspberry Pi's $25 Model A enters production, could be in tinkerer's projects early next year

Raspberry Pi‘s Model B computer will be no stranger to regular readers. We’ve seen it turn up in all sorts of projects, and generally stretched in various directions. If you were holding out for the cheaper, lower specced Model A however, your time is near. A recent post on the official Raspberry Pi site confirms that the first Model A samples are rolling off the production line. The main differences? Whereas Model B has two USB ports and 512 MB of RAM plus Ethernet, Model A sports only the one port, has half the RAM, and no Ethernet connection, making it more power economical as well as $10 cheaper. Price likely isn’t the issue here, but if you were after the even more stripped back version, it’s estimated they’ll be ready to purchase online early next year.

Razer’s Orochi gaming mouse gets laser and battery life boost

Razer has updated its Orochi gaming mouse with a new, more powerful sensor that provides better accuracy, as well as offering about double the battery life of its predecessor. You can grab the device now for the gamer on your gift list and get it in time for Christmas. The device is priced at $69.99 for those in the US, and €69.99 for those on the other side of the pond.

The Orochi can be connected two ways: wirelessly via Bluetooth 3.0, or wired for those who need a slightly more archaic connection method. The device runs a new, more precise laser, which Razer touts as the most powerful laser available in a mobile mouse. The laser sensor is a 6,400dpi 4G unit that “promises to take out the competition with deadly accuracy.”

For those who choose to use the Orochia via a Bluetooth connection, the unit is powered by two AA batteries. You can expect to get about 30 hours of continuous use, which is double the life of the previous iteration. The battery rating equals about three months of conventional usage, according to the press release.

RazerGuy Robert Krakoff offered this statement. “We want our dedicated fans to keep the ability to game at the high level they demand when they leave their home. Companies including Razer make mobile gaming laptops for that and, with those, there needs to be a mobile mouse solution. The Razer Orochi answers that need. We believe we’ve ushered in a new era of mobile gaming with the extreme performance and portability of our Blade laptop and Orochi gaming mouse.”

Harwell Dekatron revived as the world’s oldest working, original digital computer

Harwell Dekatron gets a reboot, becomes the world's oldest working, original digital computer

Over 60 years since the first digital computers switched on, the chances of seeing one of these pioneers in action have grown incredibly slim as time (and recycling) takes its toll. Take a visit to Britain’s National Museum of Computing in Bletchley Park as of today, however, and you’ll see one working. A finished 3-year restoration effort lets the Harwell Dekatron — at one point renamed the Wolverhampton Instrument for Teaching Computation from Harwell, or WITCH — claim the title of the world’s oldest functional digital computer still using its original design. Aside from its room-filling dimensions, the 1951-era mainframe may be worth the trip just for recalling a time when there were no hard and fast rules in computing: the Dekatron operates in its namesake decimal system, not binary, and puts most of its components on full display. The computer is part of the regular exhibit lineup and should be easy to see; the daunting part may be realizing that virtually any chip in a 2012 smartphone could outmuscle the Dekatron without breaking a sweat.

Project Inverted turns a gaming PC inside-out with hand-made casing

Project Inverted turns a gaming PC insideout with handmade casing

While we’ve seen some exotic PC mods in our time, most of those still dutifully stuff all the computer parts into a box, hiding them from the outside world. Martijn Laman isn’t one for that kind of traditionalism. His recently completed Project Inverted, just highlighted by ASUS, puts most of the hardware on the outside: the Sabertooth Z77 motherboard, Core i5 processor, fan cooling, memory, Radeon HD 6870 video card and watercooling pipes all sit in plain sight. Everything is joined by a unique, hand-cut case whose backbone and elevated base hide the custom wiring, the watercooling pump, two solid-state drives and controllers for both fans and lighting. And did we mention the 7-inch touchscreen? The result is a truly special gaming rig that’s relatively quiet and pristine despite baring its heart and soul for all to see. Building a replica won’t be quick, nor will it be cheap at about €1,500 ($1,909), but Laman’s detailed assembly process could well be the inspiration for a few more extroverted PCs.

Ubi Ubiquitous Computer pre-orders now available

Back in August, a tiny little computer called Ubi popped up on Kickstarter. Ubi – which is short for Ubiquitous Computer – was a big hit with Kickstarter backers. Team Ubi was only asking for $36,000, but by the time everything was said and done, the group had a whopping $229,594 to work with. It seems they wasted no time in getting to work either, as Ubi went up for pre-order today.


The Android-based Ubi plugs into a regular old power outlet and connects to the Internet through Wi-Fi. Once you’ve got the Ubi set up and ready to go, you can do things like search the Internet through voice commands. The Ubi will communicate back by either using the lights on its side or through speech, which we have to say is pretty awesome.

It can also be used to monitor the environment around you, as it comes equipped with sensors to monitor temperature, air pressure, and ambient light. You can program Ubi to send alerts to your email or your phone thanks to the handy app the Ubi team has developed for iOS and Android. The microphone and speakers on the device mean that the Ubi can also be used as a speakerphone or for conference calls, which is a nice little touch.

Even better is that you can sync Ubi to the other devices on your network. The computer is available for pre-order now, and if you manage to order one before they begin shipping in early 2013, you’ll be saving a significant chunk of change. Those who pre-order the device will only pay $219, whereas the Ubi will cost $269 once it’s been officially released. Are you picking one up?
