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."

An RFID-packing iPhone could interact with various objects including opening doors and it could even be used in shops to register items at the checkout. Beating Apple to the RFID punch, last year a company called Wireless Dynamics announced an iPhone RFID accessory called the iCarte, but if you'd rather make your own reader then you'll be interested to know how a research assistant at University College London has managed to build his own RFID iPhone accessory."

All I want is something that will run Oblivion and output full 1080 video to a TV. Last time I built my own computer I just went to Pricewatch, made a few easy choices, and everything came to my door. Do I really have to research the differences among Core i5, Core 2 Duo, Pentium 4, Pentium D, Sempron, Athlon, Phenom ...? And that's just the processor. Is there a reference somewhere? In short, how do you buy a computer these days?"

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."

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."

ptorrone writes "Hardware hacker 'Ladyada' has released an open source, retro, arcade-style, table-tennis-for-two clock called the MONOCHRON.

It includes an ATmega328 processor (with Arduino stk500 bootloader for easy hacking. It's completely open source hardware: all firmware, layout, and CAD files are yours to mess with."

watanabe writes "I just moved from a house with Cat5e wiring to a house with ... a whole bunch of coax cables. Like, my living room has five coax cables coming out of a hole in the wall. All of them go back up to my attic. The house is big, (and I like it, thank you), but I have realized that our digital usage pattern (media server + squeezeboxes + remote time machine backups to a linux box) will not work without wiring. I am currently bridging some old Linksys WRT54Gs to the right places, but of course, that slows everything down. This got me thinking: 100mb ethernet is four wires, yes? And I have four wires for every two coax cables. What about a two coax-head -> ethernet jack setup? Has anyone done this before? Searching online only gives me $100+ coaxethernet transceiver type boxes. At that price, a HomePNY system would make more sense. I'm willing to solder if I have to, but I first wanted to get advice and holes shot in my plan, if there are any."

Andrew "bunnie" Huang, whom we've discussed before for his book on Xbox hacking and development of the Chumby, has made an interesting blog post about problems he's found with Kingston microSD cards. He first encountered a batch of bad cards during production of the ChumbyOne, and found Kingston initially unhelpful when trying to get them replaced. After noticing some unusual markings on the chips, he decided to investigate for himself, comparing the ID data and dissolving the cards' casings with nitric acid to take a look inside. He found that each of his Kingston-branded samples actually had a Toshiba/SanDisk memory chip inside, and that the batch of low-quality cards he received may not be as uncommon as he thought. "Significantly, Kingston is revealed as simply a vendor that re-marks other people's chips in its own packaging. Every Kingston card surprisingly had a SanDisk/Toshiba memory chip inside, and the only variance or 'value add' that could be found is in the selection of the controller chip. ... This tells me that Kingston must be crushed when it comes to margin, which may explain why irregular cards are finding their way into their supply chain. Kingston is also probably more willing to talk to smaller accounts like me because as a channel brand they can't compete against OEMs like Sandisk or Samsung for the biggest contracts from the likes of Nokia or RIMM. Effectively, Kingston is just a channel trader and is probably seen by SanDisk/Toshiba as a demand buffer for their production output. I also wouldn't be surprised if SanDisk/Toshiba was selling Kingston 'A-' grade parts, i.e., parts with slightly more defective sectors, but otherwise perfectly serviceable. As a result, Kingston plays a significant and important role in stabilizing microSD card prices and improving fab margins, but at some risk to their own brand image."

BiggerIsBetter writes "Christopher Tarnovsky has pulled off the 'near impossible' TPM hardware hack. We all knew it was only a matter of time; this is why you shouldn't entrust your data to proprietary solutions. From the article: 'The technique can also be used to tap text messages and email belonging to the user of a lost or stolen phone. Tarnovsky said he can't be sure, however, whether his attack would work on TPM chips made by companies other than Infineon. Infineon said it knew this type of attack was possible when it was testing its chips. But the company said independent tests determined that the hack would require such a high skill level that there was a limited chance of it affecting many users. ... The Trusted Computing Group, which sets standards on TPM chips, called the attack "exceedingly difficult to replicate in a real-world environment."'"

With every software update, the previous generation of "jailbreaks" stop working, and people have to find new ways to break into their own computers. There won't ever be a MacsBug for the iPad. There won't be a ResEdit, or a Copy ][+ sector editor, or an iPad Peeks & Pokes Chart. And that's a real loss. Maybe not to you, but to somebody who doesn't even know it yet.'"

An anonymous reader writes "Wish you could start your car via your cell phone, but don't feel like ponying up the $40k for a Chevrolet Volt or $499 (plus $29 a year) for an aftermarket system from Viper? This hack relies on a cheap prepaid cellphone that has had its vibration motor surgically removed, replaced by a couple of leads triggering the car's starter. Whenever the phone receives a call it starts up the car — a somewhat dodgy proposition if a telemarketer ever gets hold of your number, but an interesting solution nonetheless. Total cost of the project: $71.03."

conner_bw writes "Imagine strumming a guitar without any strings, on a touchscreen. Think the idea is too far-fetched? The Misa digital guitar claims to be exactly this. Overcoming the natural limitations of a traditional guitar, this new instrument eliminates the need to pluck strings while using the right hand to control sound. Specs: Linux kernel 2.6.31 (Gentoo); 24 frets; touchscreen; MIDI out; RJ-45 Ethernet. My favourite parts of the site are the FAQ (How do you SSH into the guitar?), and this quote from the developer: 'Because the software is open source I'm hoping people completely change the instrument and share new "firmware" with others. Different graphics, different control ideas etc. It would all be free of charge. So I'm hoping that happens as the instrument becomes more familiar.'" The developer, Michael, has not yet promised a delivery date or set a price for the instruments he is manufacturing.

Shah spent £20,000 on the equipment, hooking up a telescope in his shed to his home computer, and the results are being compared to images taken by the Hubble Space Telescope. 'Most men like to putter about in their garden shed,' said Shah, 'but mine is a bit more high tech than most. I have fitted it with a sliding roof so I can sit in comfort and look at the heavens. I have a very modest set up, but it just goes to show that a window to the universe is there for all of us – even with the smallest budgets. I had to be patient and take the images over a period of several months because the skies in Britain are often clouded over and you need clear conditions.' His images include the Monkey's head nebula, M33 Pinwheel Galaxy, Andromeda Galaxy and the Flaming Star Nebula, and are being put together for a book."

itwbennett writes "The 3D porn experience is coming (eventually) to a home theater near you. Most adult filmmakers are moving slowly toward 3D video because of higher production cost, the small number of 3D TVs in the home, and, of course, the glasses. Rob Smith, director of operations at Hustler Video Group says he hopes that market penetration of 3D TVs in the home is high enough that 'by the fourth quarter of this year it will be at the point where we can justify doing a 3D product.' The average adult movie costs around $25,000 to $40,000 to make, and 3D movies cost about 30% more, says Ali Joone, founder of Digital Playground. But Joone thinks the biggest hurdle for 3D isn't so much the cost as the glasses: people don't want to be encumbered by eyewear when viewing a film, says Joone."
