[Elf] sent in this interesting DIY joystick glove. There aren’t many details on the actual glove switch design, but from the schematic on the site, it seems to mostly consist of micro-switches with some pot adjusted transistors to calibrate the X-Y signals.

You might remember [Janne]’s IKEA cluster. Now he’s got a couple of dream rigs in mind, so he started doing 3D renderings of them. Helmer 2 is designed to contain 24 video cards attached to six motherboards with quad core CPUs. (AMD has even taken enough interest to send him some cpus to get started) The rendering really comes in handy for designing the custom copper heat pipes and the aluminum cooling fin enclosure. Still bored, he put together a rendering of a 4 PetaFLOP machine using 2160 video cards.
Update: The Helmer 2 link is fixed.
[Jipa] over at MetkuMods put up an original re-use for old hard drives: make em into power tools. The tiny servo motor that drives the spindle doesn’t generate much torque, but once the drive is spinning fast enough, the inertial force of the platter is enough to make it usable for small grinding/sanding projects. The platters are re-stacked directly on top of each other to increase strength – we’d suggest a few dabs of epoxy to make em even stronger. Once stacked, a piece of sand paper is cut to size and held on by the center platter washer. [Via hacknmod]
InformationWeek has great article on open source data recovery tools. What type of tools you use will depend on the severity of the situation. You can use live Linux distros designed for recovery like SystemRescueCD or Partedmagic (the latter being more user friendly). Security tools distrubutions like BackTrack can also be helpful; Helix in particular was designed for forensics work. dd is a standard *nix tool for imaging drives, but something like TestDisk can help you repair partition tables for whole disk recovery. Most deletion operations don’t overwrite the data which means you can use file carving to capture the lost files. PhotoRec is able to find files in a number of common formats. Finally, if you’ve got some serious forensic work ahead of you there’s The Sleuth Kit and many other command line tools.
As an addendum, OStatic put together a list of 5 freeware tools for protecting your system.
The people at TweakTown completely disassembled a new Eee PC 1000H and documented the entire process. Aside from showing you the side effects of too much tech fetish and not enough regular fetish, the article reveals all the parts of the new Eee, with a few surprises inside. Although it’s an Eee PC, it’s very different from all of its predecessors.
One of the things the teardown shows is that several parts are far more modular than previous Eee PC models. The hard drive, for example, is a standard Seagate Momentus which is made for desktop systems; it can easily be swapped out. Another easily swapped component is the 1GB SIMM from ASint.
Although their (ahem) stripping process was a bit unconventional, a lot of interesting information was yielded from this teardown. Keep ’em coming, TweakTown, just be sure to clean off your tool when you’re done.

The folks from bit-tech have done us a great service by tearing open the Eee PC 901. Under the keyboard is a large metal plate that acts as the processor’s heat sink. The 4GB SSD card is not soldered to the board this time around. There is some empty space labeled IDE3 and solder points that say 3GCard, which definitely deserve further investigation. The oddest thing they found was a button with no indication to its purpose. It looks like a good machine and we hope to see more Eee PC hacks in the future.

With the imminent release of Firefox 3 and Opera 9.5 being finalized this week, Lifehacker decided it was a good time to run the browsers head to head to see which was the fastest and least resource intensive. The testing system was a 2GHz 2GB Vista machine. The timing system used wasn’t directly hooked to the browser, so tests were repeated multiple times to improve accuracy. The cold start winner was Opera, but most browsers opened in about a second if they had been run recently. Safari did well loading content in multiple tabs at the same time, probably due to its short render times for JavaScript and CSS. The final test was memory usage; we’re sure many people will be happy to know that Firefox 3 RC3 only used 66% of the RAM required by the other three browsers.
