Dell Adamo Teardown

TechRepublic and iFixit partnered to teardown Dell’s flagship notebook, the Adamo. The Adamo is positioned to compete directly with Apple’s MacBook Air. The Dell crams a lot of technology into a very thin frame and they use a clever locking system for the backplate to hide any screws. The built in battery has a longer life than the Air and an SSD comes stock. The team points out that the Windows logo is etched on the backside instead of the standard ugly stickers; apparently this took quite a bit of teeth-pulling to get approved. Check out the full photo gallery which includes the fetish packaging and comparison shots to the Air and Dell Mini 9.

FIELD A Fluorescent Array, Wirelessly Powered

What would you do if you were driving along the highway and you glanced into a field to see a giant array of fluorescent tubes lit wirelessly from the electromagnetic fields of power lines. Back in 2004, [Richard Box] set up this display after hearing about a friend playing “light saber” with fluorescent tubes under power lines. The tubes can be lit pretty easily by have a variation in voltage between the ends. By sticking one end in the ground and the other up in the air, he’s harnessing the strong magnetic field from the power lines. Though some thought the display was made to bring people’s attention to possible hazards of living near the lines, [Box] states that he did it just because it looked cool.

Stepper Motor Controller From Old Scanner

[Murray484] submitted his instructable on how to create a stepper motor controller from an old scanner. He removed the motor and controller from an old scanner then harvested the parts. He’s pretty much starting over, taking the ULN2003 chip from the scanner motor controller and putting it on a fresh board. He then wired it all up, installed the software and got it working. Finally, he built a container out of cardboard for it all. Though he could have made it nicer looking and used higher quality building materials, he was trying to make this a “green” project for the epilog laser cutter contest. He’s done a good job recycling, this could be pretty useful.

The CrunchPad Tablet Shows Its Face

After a few pictures of the CrunchPad tablet leaked onto the internet, Crunchgear decided to release some more info.  The prototypes you see are fully functional, have Intel Atom processors, and a 12 inch capacitive touchscreen. There isn’t much else available yet as far as details. What we’re most curious about is how the interface works. As many people who have used tablet PCs or touchscreens know, it’s usually the software interface that makes or breaks the experience. We’ve been curious since TechCrunch talked about what netbooks should be. Can’t wait for some videos.

Removable Router Antenna

[Mike] takes us through the process of adding  a removable high gain antenna to the WRTSL54GS in this article. The antenna that comes on this unit from the factory is a bit small and underpowered. After upgrading it using OpenWrt, an open source full featured router software package, he felt it needed a beefier antenna. So, he cracked it open. The new antenna can simply be soldered in place, where the old antenna was.
