Salad Spinner Made Into Life-Saving Centrifuge Screenshot-sm 87

Posted by samzenpus from the kitchen-and-lab-equipment dept.
lucidkoan writes "Two Rice University students have transformed a simple salad spinner into an electricity-free centrifuge that can be used to diagnose diseases on the cheap. Created by Lauren Theis and Lila Kerr, the ingenious DIY centrifuge is cobbled together using a salad spinner, some plastic lids, combs, yogurt containers, and a hot glue gun. The simple and easily-replicated design could be an invaluable tool for clinics in the developing world, enabling them to separate blood to detect diseases like anemia without electricity."

Open Source Router To Replace WRT54GL? 344

Posted by timothy from the need-a-beamer dept.
jeremyz writes "With the inclusion of 802.11n in more and more Wi-Fi devices, the WRT54GL is losing its usefulness, even though it's still the de-facto standard for open source, Linux-running wireless routers. I've been looking around for a 802.11n router to replace the WRT54GL, but haven't really found anything besides the Netgear's WNR3500L. At first look, the WNR3500L looked great, but after some further investigation, I found that Netgear hasn't released all of the source, as they should have to comply with the GPL. Are there any good 802.11n routers to replace my aging WRT54GL?"

anethema writes "iPhone hacker planetbeing, from the iPhone Dev Team, has successfully ported the Android OS over to the iPhone. He is doing it on a first-generation iPhone, but others may be possible. The port is pretty functional, with data, voice, and many apps working, although it is running a bit sluggish and buggy at the moment. There appears to be much work left."

Hidden Cores On Phenom CPUs Can Be Unlocked 251

Posted by CmdrTaco from the what-could-possibly-go-wrong dept.
An anonymous reader writes "One of the major ways a semiconductor manufacturer manages to make the most of its chips is through binning. Chips able to cope with high clock speeds with all cores running end up as premium product lines, while others end up as models rated at lower speed grades, or with fewer cores. In the case of AMD's Phenom CPUs, dual and triple core models are quad cores with some disabled, while some newer quad core CPUs are actually six core models with two disabled. To this end both ASUS and MSI have announced that they have modified versions of AMD 890FX- and 890GX-based motherboards to unlock these hidden cores. Much like overclocking, there is no guarantee that you will gain anything by unlocking the hidden cores — everything depends on just why your CPU ended up in a certain product line."

In Defense of Jailbreaking 405

Posted by CmdrTaco from the fighting-the-good-fight dept.
Keith found a nice manifesto saying "There's a trend that's been disturbing me lately. When the topic of modding or jailbreaking comes up — say, in the wake of the iPad announcement, or Sony's restrictive PS3 update — there is an outcry. Who am I to tell Apple what's best for their devices?"

Where To Start In DIY Electronics? 301

Posted by Soulskill from the hold-off-on-the-homebrew-lightsaber dept.
pyrosine writes "I've been thinking about this for a while and have no idea where to start. I have little or no previous experience in electronics — just what is covered in GCSE physics (wiring a plug and resistors — not much, I know). The majority of my interest lies in the wireless communication side of the field — i.e. ham radios and CB — but I am also interested in how many things work, one example being speakers, simply to better understand it. I would preferably like to start with some form of practical guide rather than learning the theory first, but where I would find such a walkthrough eludes me."

How Neuros Built Their Nearly Silent HTPC 199

Posted by timothy from the more-power-than-my-best-machine dept.
JoeBorn writes "Neuros has a blog posting discussing how they created their latest 'thin' HTPC to be nearly silent. Instead of using a net-top architecture (Atom or the like) they used a full 2.7GHz CPU and put their effort into making that nearly silent. The article talks about their efforts on fan selection, placement, control, and vibration dampening. This route was chosen to 'give more headroom' for CPU-hungry apps (web and otherwise) including Adobe Flash. Their solution costs $279; is this an appropriate trade-off for a device powering your TV?"

DIY 80GB iPod Touch 110

Posted by timothy from the cloudy-today dept.
An anonymous reader writes "Having recently acquired an iPod Touch, DeviceGuru blogger Rick Lehrbaum soon found himself with an 80GB iPod paperweight knocking around and collecting dust. Then it hit him: why not use a Pogoplug as an iPod server, effectively filling his nifty new iPod Touch with 80GB of music whenever he has WiFi access? The how-to article at DeviceGuru.com explains how a Pogoplug and iPod Touch combined with free web services at pogoplug.com combine to form the 'PogoPod System.' It also introduces the Pogoplug's new UPnP support, and briefly reviews a couple of UPnP media-rendering iPhone and iPod Touch apps."

Ed Roberts, Personal Computer Pioneer, 1941-2010 110

Posted by timothy from the set-things-in-motion dept.
A user writes "CNET and the Huffington Post both report the death of Henry Edward Roberts, best known to all of us as the inventor of the Altair computer, at the age of 68 from pneumonia. As it happens, I never got to use an Altair, but I did meet Ed once, back in the mid-1980s. Since that time, I've never referred to the Altair bus as the 'S100' bus, since I agree with him that an inventor is entitled to name his invention." Updated 7:40 GMT by timothy: Roberts was 68, not 88 as originally stated; thanks to the readers who pointed out the typo.

From his FAQ: 'While thinking about Turing machines I found that no one had ever actually built one, at least not one that looked like Turing's original concept (if someone does know of one, please let me know). There have been a few other physical Turing machines like the Logo of Doom, but none were immediately recognizable as Turing machines. As I am always looking for a new challenge, I set out to build what you see here.'"

Firmware Hack Allows Video Analysis On a Canon Camera Screenshot-sm 115

Posted by timothy from the turn-your-family-green-with-envy dept.
An anonymous reader writes "Researchers from the University of Liege in Belgium have been able to perform real-time video analysis on a regular Canon digicam (video link) without any hardware modification. The results are shown directly on the digicam's screen. They use a hacked version of a popular open-source alternative firmware for Canon cameras: CHDK. This is a proof-of-concept that computer vision algorithms can now be embedded on regular Canon digicams with little effort (CHDK is coded in C). What other popular vision algorithms could be implemented? For what purpose?" You can get some idea about ViBe from this abstract at IEEE; basically, it allows background extraction in moving images.

Mario Reduced To 8x8 With Open Source and Arduino 94

Posted by timothy from the demand-2-by-2 dept.
adeelarshad82 writes "The open-source Arduino electronics platform has received a ton of attention from the hardware enthusiast community. And one more follower is joining the fray — Mario himself. The mustachioed plumber of console video game fame has been converted into an eight-by-eight LED matrix by Carnegie Mellon University student Chloe Fan. However, the game isn't quite the Mario you know from your legacy Nintendo Entertainment System. For starters, it's just lights. While one often sees the game's LED-backed grid used in devices like the open-source Monome, where it can function as a push-button toggle for music beats and effects, Fan's version of Mario uses the grid as a display only. Mario — or rather, a one-light representation of the game's hero — is controlled NES-style through the use of two buttons. One button makes Mario move forward; the other makes him leap into the air."

This makes it possible to retrofit a screen to one fully readable in direct sunlight. In her blog, Mary Lou Jepsen says: 'It’s only slightly more difficult than changing a lightbulb: it’s basically 6 screws, pulling off a bezel, unconnecting the old screen and plugging this one in. That’s it. It’s a 5 minute operation.' She also talks about the 'laptop hospital,' a service depot started by kids in Africa."

Write Bits Directly Onto a Hard Drive Platter? 578

Posted by kdawson from the old-old-skool dept.
kidcharles writes "I'm working on a project that requires writing bits to a magnetic hard drive platter in a completely controlled fashion. I need to be able to control exactly where 1s and 0s will appear physically on the platter. Normally when data is written to a drive the actual bits that get written are determined by the file system being used, as modified by whatever kind of error handling the drive itself is using (e.g. Reed-Solomon). All of the modern innovations in file systems and error handling are great for reliable and efficient data storage, but they are making my particular task quite daunting. My question for Slashdot: is there a way to get down to the 'bare metal' and write these bits? Any good utilities out there to do this? Obviously a free and open source solution would be preferable, but I'm open to anything at this point."
