SLI, for those who don’t know, is the process of taking two Nvidia graphics cards and allowing them to work in parallel to render to a single monitor. In theory this doubles the power, getting more FPS for video games. Great right? Except due to encryption, only a limited amount of motherboards can actually support SLI.
That is, until now. Russian hackers at xDevs discovered that the newer encryption is based around string identifiers. This can be modified within the operating system itself, so in theory any motherboard could work. Be wary, this could brick your system; but if successful, you’ll have more power without shelling out for an officially SLI supported motherboard.
This silly little video caught our attention. It is an alarm clock, hacked with two amazingly loud car horns. They are using a laptop power brick to push the two external car horns. The horns are triggered by a relay wired to the internal speaker of the alarm clock. This is a super quick project that could be done, not only to help yourself, but it is the perfect amount of effort for a prank. We bet you guys could probably wire one of these up and hide the horns in only a few minutes. If you are having problems waking up, you might also want to check out some of the other alarm hacks we’ve seen.
[Steve] sent in a tip to show us his Thermography scanner. Constructed from an Arduino, two servos, a thermal sensor and a little bit of code, it is fairly simple. The results aren’t groundbreaking. You can see his examples are fairly low resolution and took about 30 seconds to capture. It isn’t bad for a quick project though. The source code is available on his site.
Earlier this year we were amazed when University of California researchers controlled a beetle via electrical implants. The video available at the time of the original report showed beetles tethered in place while electrical stimuli was applied via the chip. New video of free flight is has now been posted. Although the motion is rather sporadic, it is obvious that simple commands to start flight, stop flight, and turn left or right are having their intended effect. Check out this cyborg action after the break. Is DARPA one step closer to unleashing legions of insect warriors on unsuspecting masses? Continue reading “Radio controlled beetle flight footage”
Hot on the heels of our post about reading passwords from EEPROM, [n0th1n6] tipped us off about a similar hack used to resurrect an Eee PC from a bad bios flash. After discovering that a factory repair for a dead bios costs about $200, [CutenaCute_7] took on the challenge herself. She disassembled the computer and desoldered the bios chip from the board. After writing a program to flash the chip using C#, she temporarily soldered jumpers to make sure the flash worked. Looks like this is a zero cost hack, plus the time savings from not having to ship her computer somewhere. Bravo.
Google has unveiled their latest web app. It’s called Google Sidewiki and makes it easy to “Contribute helpful information to any webpage”. We’re not quite so sure. If you have the Google Toolbar installed on your browser, Sidewiki allows you to open a side-panel, add your comments about the page, and read the comments of others.
In a Utopian Internet (Utopernet?) the world’s most predominant experts on all subjects would be browsing websites dropping off clairvoyant nuggets of wisdom like Greek oracles. In reality, letting anyone add to any web page does not equate to instant insight. We’re all familiar with long comment threads and forum posts that contain very low percentages of useful information.
Google considered this “white noise” as a possible problem and implemented a ranking system for which comments are displayed first. This raises another flag, will this become a type of advertising? At some point in the future will comments linking to other pages be ranked based not only on popularity, but on a kickback to the Big G in return for increased exposure?
There is also the consideration that web pages might not like what comments are being left in Sidewiki. We’ve noticed that emails referencing the Labor Movement often have link advertisements in Gmail about how to prevent Unionization. What would the Sidewiki for pages covering controversial topics such as religion, sexual persuasion, and abortion look like?
We will admit this is a well intentioned idea with a lot of potential. But everything depends on how well it is executed.
[Hunter Davis] keeps rolling out the hacks for the Zipit. In the past he showed us how to run DOSbox, and then how to get NES emulation working on this tiny device. Now he’s got Linux kernel 2.6.29 running Fluxbox with mouse (newly added), audio, and WiFi functionality. Follow his step-by-step flashing instructions to load the kernel into the Zipit. Once flashed, a partitioned microSD card servers as the filesystem and swap.
Who needs a 10.1 inch screen or an Atom processor when you can get this 2.8″ QVGA beauty with an XScale processor for around $40?
