EFiX Dongle Still Not Available

June 23, 2008 by 15 Comments


Well, it’s June 23rd, and still no dongle from EFiX. Despite a new product page on the company’s site, the OS X installing dongle is still not available for purchase. The USB dongle is supposed to facilitate the installation of Mac OS X by booting the Leopard install DVD on PCs, but so far no one has been able to verify this claim as no one has one of these in their hands yet. We’ve been covering this story since the beginning, and we’ll be sure to let you know when you can actually buy one of these.

Air Hockey Robot

June 23, 2008 by 9 Comments


Don’t be ashamed, we suck at air hockey too. Luckily for us, we now have a robot opponent to blame or losing streak on. Engineers at Nuvation didn’t build this air hockey playing robot, they simply adapted a standard industrial robot arm for the task. It is controlled jointly by a ColdFire processor and a 9S08 microcontroller. An array of high power LEDs and a camera are positioned over the air hockey table, which captures the position of the puck. The robot reportedly wins 90% of its games, even against solid opponents. While this is more of project to show the power of ColdFire processors, we can’t help but think it will lead to a rash of unbeatable robot opponents. We’ve already been robo-owned at foosball; what’s next?

Tube Amp Monitor

June 23, 2008 by 5 Comments


Sparkfun contributor [Pete] really loves tube amps, but he’s a very safety-conscious guy who doesn’t like being electrocuted. This is a problem, since tube amps are usually very high voltage, and a small mistake can be fatal. To deal with this voltage issue, he built a tube amp with a control system built around a 6DOF v3 controller board. The control system is there mainly in case of a failure, automatically shutting off the high voltage transformer in any such event. It has the added benefit of filtering any 60Hz noise from getting into the audio, which happened before he installed the control system.

In addition to regulating power, the controller board also monitors bias points in the output tubes and displays its diagnostics on an LCD. Aside from getting great sound from the tube amp, [Pete] made it look great too, installing colored LEDs under the tubes. We love his design: just because safety comes first it doesn’t mean cool-factor can’t come in a close second.

OLPC Dual Booting

June 23, 2008 by 11 Comments


Gizmodo has the first ever footage of an OLPC dual-booting both its default OS, Sugar Linux, and Windows XP. The BIOS was not originally intended to boot XP, so it had to be modified for this to work. The XO’s screen flipper and directional buttons work in XP as well.

It’s not all good news, though: XOs are designed to be ultra-lean, packing a meager 256MB of RAM, which is hardly ideal to run XP. Booting it alone took an eternity, so we can’t imagine anyone doing anything practical with this. The machines will never ship with only XP installed.

Xbox 360 Modding Case Details

June 23, 2008 by 15 Comments


If you’ve been wondering about what changes Lian-Li implemented in their commercial XBox 360 casemod called the PC-XB01, they’ve recently updated their product page.

The case does not add any new functions to the console, but it improves its efficiency on several levels. To deal with the noise produced by the DVD drive, they installed sheets of sound insulation foam around the drive, greatly reducing the sound it makes when it spins up. They did even more for temperature control, replacing the standard dual 70mm fans with a single 120mm fan that cools more efficiently and quietly. The case is also larger and features a frontside grate, allowing for vastly improved airflow. Lian-Li designers even left opening in the back for option water tubes in case you want to add a liquid cooling system.

High Tech Coffee Tables

Time was, coffee tables were good for three things only: setting down your coffee, setting down your coffee table books, and maybe putting your feet up. To combat this perception, Born Rich has posted their top ten list of high tech coffee tables that are capable of these things and more.

Add A Second Internal Hard Drive To Your Laptop

June 23, 2008 by 17 Comments


[Andrew] sent in something we’ve been considering for our 17 inch Dell. He squeezed a 100GB PATA notebook drive into the spare space in his Compaq laptop. He used a USB interface to provide the connection and added a toggle switch to conserve power when he doesn’t need the drive spun up. The mod would be even nicer if you added a keyboard activation switch like [sprite_tm]’s keyboard light.
