Thursday, July 17th, 2008Filed under: pcs hacks, peripherals hacks, daily
[sprite_tm]’s back with one of his excellent Atmel projects. This time he decided to turn an original XBox controller (cause he likes ‘em) into a standard USB HID device. He gutted the custom USB chip that Microsoft installed and replaced it with an Atmel ATMega88. The ATMega required a few changes to the board, but nothing too off the wall.

SenseSurface: Custom inputs on your lcd screen
Tuesday, July 15th, 2008Filed under: pcs hacks, peripherals hacks
[Lindsay Williams] has come up a novel way of constructing custom physical inputs for your programs. SenseSurface is a viable alternative to building a new interface for each application. Simply place the dials, buttons, and sliders on your screen wherever you want them.
A sensor board, placed behind the display, picks up the signals from the inputs. The only limitation to the number of inputs available is the size of your screen. Inputs are held on magnetically, and have a low friction backing to avoid scratching or gouging your screen.
DIY joystick glove
Monday, July 14th, 2008Filed under: pcs hacks, peripherals hacks
[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.

Render your next render farm
Saturday, July 5th, 2008
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.

Turn your old hard drive into a sander/grinder
Friday, June 27th, 2008Filed under: misc hacks, pcs hacks, peripherals hacks
[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]

Open source data recovery tools
Tuesday, June 24th, 2008Filed under: pcs hacks, security hacks
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.
Eee PC 1000H dissected
Sunday, June 22nd, 2008Filed under: pcs hacks
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.
Eee PC 901 teardown
Tuesday, June 17th, 2008Filed under: pcs hacks
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.
Speed testing the latest web browsers
Friday, June 13th, 2008Filed under: pcs hacks
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.

EFiX boots Leopard retail DVDs on generic hardware
Thursday, June 12th, 2008Filed under: macs hacks, pcs hacks
On June 23rd, EFiX is planning on releasing a USB dongle that will let any PC boot and install OSX from a retail DVD. The commercial device is supposed to take care of all patching and other woes OSX86 enthusiasts have had to deal with. Very little information is provided other than a statement that the development process took a lot of time and that they overcame “sabotage”… so, it’s got that going for it. Major OSX86 contributor (and Psystar hater) [Netkas] received a device to test and was pleased with the results. We’re just going to wait and see what happens. Not that it matters; they have no plans of releasing it in the US.
Synaptics trackpad swap
Wednesday, June 11th, 2008Filed under: laptops hacks, pcs hacks, daily
Some people are really picky about their trackpads. [John] posted a guide on retrofitting a Synaptics pad in place of the newer, but less user friendly ALPS touchpad/stick combo used in the Dell Inspiron 8200. On the opposite end, [C. Järnåker], loves laptop keyboards enough to mod them for use on his desktop machine.

Touchscreen kit for Eee PC
Sunday, June 1st, 2008Filed under: pcs hacks
We’ve featured hacks for the Eee PC 701 before, but nothing so easy as this touchscreen kit.
This kit includes everything needed: the touchpanel, a USB controller card, and the correct connectors. The touchpanel is placed inside the frame in front of the screen. The controller is plugged in line with the USB webcam. This mod can be completely installed in 9 steps, the hardest of which involves removing a few screws. This is great solution for first-time modders, but if you’re not afraid of a little solder and prefer a bit more challenge, check out jkkmobile’s original touchscreen hack. He even hints that he’s successfully added touch to his Eee 900 as well.

Open graphics card available for preorder
Wednesday, May 21st, 2008
The Open Graphics Project has started accepting preorders for their OGD1, a graphics card with a completely open source design. This initial release is billed as a high-end FPGA prototyping kit specifically designed to test computer graphics architectures. The card has two DVI connectors, S-Video, 256MB RAM, and a 64bit PCI-X connector. The core of the system is a Xilinx Spartan-3 XC3S4000 FPGA. A nonvolatile Lattice XP10 FPGA is used to bootstrap the Xilinx at power up. Here’s the layout of the specific components.
Buy Ben’s PS3 Laptop

Just a little public service message: If you've been drooling over [Ben]'s work and have plenty of loose change, his PS3 laptop is up for auction to benefit the National Cancer Coalition.

24 core Ikea cluster
Wednesday, April 23rd, 2008Filed under: pcs hacks
[Janne] does freelance animation and wanted something with a bit more CPU to get his rendering jobs done. He picked up an Ikea 'Helmer' cabinet and refitted it to hold six Intel quad cores, six Gigabyte motherboards with 8GB of ram each and six 400 watt power supplies. He seems happy with it - I think it just needs some custom power wiring and an integrated Gig-E switch to achieve perfection. What? I'm not jealous at all.Read | Permalink | Email this | Linking Blogs | Comments
