tunersedge writes "Yesterday I dug out of my parents' basement a PC they had bought brand new in 1984: Epson Equity I personal computer; 512K RAM; 82-key keyboard; 2 (count 'em!, 2) 5.25" floppy disk drives; 13' RGB monitor (with contrast/brightness knobs); handy on/off switch; healthy 25-year-old yellowed plastic; absolutely no software. (My mom ran a pre-school, and they used it to keep records and payroll. I cut my programming teeth on this thing. GW-Basic was my friend. Kings Quest screens took 2 minutes to load when you walked into a new one.) When I resurrected this machine I pulled the case off, dusted out a little, and plugged it in. It actually fired up! I'm stoked, except the disks we had are missing. What I'm looking to do is either buy some old working disks with whatever I can find (MS-DOS 3.22, GW-Basic, whatever), or try and recreate some using a USB-based floppy drive and some modern software. Has anyone tried to resurrect a PC this old before?"

gigne writes "I'm in the market for a new, in-car GPS/sat nav. I am preferably looking for one that has live, up-to-date traffic information and route planning that doesn't make you want to cry. I'm not quite dumb enough to drive off a cliff, but something that doesn't even try and lead me to watery doom is preferable. The only thing I absolutely must have is the ability to hack it. It would be preferable if it ran GNU/Linux, but given a convincing argument, I would be swayed to another OS. Without wanting the Moon on a stick, what is the best device that would offer a decent modding community and a good feature set?"

tramm writes "I've released an extension for the Canon 5D Mark II DSLR's video mode to enable functions that are useful for independent film makers. While the camera produces a great movie out of the box, the audio is a severely limited. My code adds features that should have been in the software, like on-screen stereo audio meters, live audio monitoring, reduced audio noise and crop marks for different formats. An introductory video shows the new features in use and an audio evaluation compares it to the stock firmware with very good results. It's similar to the incredibly flexible CHDK software for Canon's point-and-shoot cameras, but targeted at the film makers using the 5D. The Magic Lantern firmware is GPLed and new features will be written to make the camera even more useful on set. There is a wiki for documentation and development."

Nicola Asuni writes to let us know about a new resource for hardware hackers: a wiki about pinouts — hardware interfaces of modern and obsolete hardware. "Created with the same MediaWiki software that was developed for the Wikipedia project, AllPinouts.org is a wiki that allows users to get and share information about hardware interfaces, including pinouts of ports, expansion slots, and other connectors of computers and different electronic devices (i.e. cellular phones, GPS, PDA, game consoles, etc.). All text is available under the GNU Free Documentation License and may be distributed or linked accordingly. The 'pinout' (or 'pin-out') of a connector identifies each individual pin, which is critical when creating, repairing or hacking cable assemblies and adapters."

An anonymous reader writes "Johan Van den Brande has developed a Twitter client for the Commodore 64, allowing 140-character messages to be posted directly from this TV-connected 1982 home computer. This YouTube video shows how the Twitter client is — slowly! — loaded from a 5.25" floppy disk, how the latest Twitter messages are downloaded and shown on the TV screen, and how this tweet is posted. All that is needed is a C64, a TV, and a C64 Ethernet card. The Twitter client is implemented with the Contiki operating system, which otherwise is used for connecting tiny embedded systems to the Internet."

mbone writes "In the New York Times, there is an interesting story about a hydraulic analog computer from 1949 used to model the feedback loops in the economy. According to the article, 'copies of the 'Moniac,' as it became known in the United States, were built and sold to Harvard, Cambridge, Oxford, Ford Motor Company and the Central Bank of Guatemala, among others.' There is a cool video of the computer in operation at Cambridge University. I remember that the Instrumentation Lab at MIT still had an analog computer in its computer center in the mid-1970s. Even then, it seemed archaic, and now this form of computation is largely forgotten. With 14 machines built, it must have been one of the more successful analog computers — a supercomputer of its day. Of course, you have to wonder if it could have been used to predict our current economic difficulties."

MaizeMan writes "Not for the easily distracted: a Belmont software developer's hand-built CPU was featured in Wired recently. Starting with a $50 wire wrap board, Steve Chamberlin built his CPU with 1253 pieces of wire, each wire wrapped by hand at both ends. Chamberlin salvaged parts from '70s and '80s era computers, and the final result is an 8-bit processor with keyboard input, a USB connection, and VGA graphical output. More details are available on the developer's blog."

EdIII writes with this awesome snippet from Hack a Day: "'[phreakmonkey] got his hands on a great piece of old tech. It's a 1964 Livermore Data Systems Model A Acoustic Coupler Modem. He recieved it in 1989 and recently decided to see if it would actually work. It took some digging to find a proper D25 adapter and even then the original serial adapter wasn't working because the oscillator depends on the serial voltage. He dials in and connects at 300baud. Then logs into a remote system and fires up lynx to load Wikipedia. Lucky for [phreakmonkey] they managed to decide on a modulation standard in 1962. It's still amazing to see this machine working 45 years later.' Although impractical for surfing the Internet today, there is something truly cool about getting a 45-year old modem to work with modern technology. The question I have, is what is the oldest working piece of equipment fellow Slashdotters have out there? I'm afraid as far back as I can go is a Number Nine Imagine 128 Series 2 Graphics card on a server still in use at my house which only puts me at about 14 years."

ThinSkin writes "Building a computer that can handle today's games doesn't have to cost an arm and a leg. In fact, you can build one for less than $800, especially given that many hardware manufacturers have cut costs considerably. Loyd Case over at ExtremeTech shows gamers how to build an $800 gaming PC, one that features an overclockable Intel Core 2 Quad Q8400 and a graphics-crunching EVGA 260 GTX Core 216. The computer exceeded expectations in gaming and synthetic tests, and was even overclocked well over spec at 3.01GHz."

stevel writes "The owner of games site GamesByEmail.com created Dice-O-Matic, 'a machine that can belch a continuous river of dice down a spiraling ramp, then elevate, photograph, process and upload almost a million and a half rolls to the server a day. ... The Dice-O-Matic is 7 feet tall, 18 inches wide and 18 inches deep. It has an aluminum frame covered with Plexiglas panels. A 6x4 inch square Plexiglas tube runs vertically up the middle almost the entire height. Inside this tube a bucket elevator carries dice from a hopper at the bottom, past a camera, and tosses them onto a ramp at the top. The ramp spirals down between the tube and the outer walls. The camera and synchronizing disk are near the top, the computer, relay board, elevator motor and power supplies are at the bottom.' While not called out in the article, the pictures clearly show a Dell Mini 9 running the show (and performing the optical recognition of the dice values.) No, it's not running Linux."

Guanine writes in with a follow-up to our discussion a few months back on the SheevaPlug: 1.2-GHz ARM-compliant processor, 512 MB DDR2, 512 MB flash, USB 2.0, gigabit ethernet, in a package the size of a wall wart, for $99. Saul Hansell's Bits Blog in the NY Times talks about a few applications for such a device, whose price point Hansell claims will drop to $40 before too long. "The first plausible use for the plug computer is to attach one of these gizmos to a USB hard drive. Voila, you've got a network server. Cloud Engines, a startup, has in fact built a $99 plug computer called Pogoplug, that will let you share the files on your hard drive, not only in your home but also anywhere on the Internet. ... [Marvell's CEO said] 'Eventually you won't see the plug. We want this device to be in your TV, your stereo system, your DVD player.'"

An anonymous reader writes "A Piezoelectric Sound Level Meter was demoed at MIT's Battle of the Bands last month, borrowing its display from the do-it-yourself USB LED marquee that was the subject of a previous Slashdot story. This video tutorial describes in detail both the analog electronics plus the C code that runs the system. If this is your first experience at the intersection of digital and analog systems, don't be scared!"

macson_g writes "Students from Wroclaw University of Technology (Poland) once again turned one of their dormitories into huge display. The project is called P.I.W.O. (B.E.E.R.). This time they converted a 10-story building into 4-color, 12x10 display. The business was used to display animations, and to play interactive games as well. On the project page (in Polish, Google translation here) you can watch an almost hour-long video, featuring music videos, a Tetris session, a dancing Michael Jackson, Duke Nukem and Mario."

destinyland writes "Want to build a robot this summer? 'Robot-loving Japanese are tinkering with screwdrivers and motors instead of heading to the beach,' and this article identifies the stores and sites serving robot hobbyists. Several sites are actually selling leftover industrial robots, but there's a variety of smaller-size robot vendors, from Tokyo's Vstone Robot Center to Carl's Electronics in Oakland (which sells sound-activated 'Hydradzoids' and solar-powered robots that crawl). Hasbro even sells their own functioning R2-D2 droid with real sonar navigation and a 'voice recognition response module.'"

DefenseSupportParty writes "I recently traveled via an unnamed airline, and stupidly checked my laptop. Unfortunately, the screen broke in transit and they refuse to take responsibility for it, claiming that it could have been broken before the flight. I'm not really in the mood to replace the screen if I have to pay for it, as I have other laptops that I can use. At the same time, I don't want to waste computing power that could be put to good use. I've thought about the common stuff: file server, SETI@Home, but I'd like to do something a little more creative. Does anyone have good ideas for a relatively powerful laptop without a display?"

Hugh Pickens writes "The Electronic Frontier Foundation has filed suit against Apple to defend the First Amendment rights of BluWiki, a noncommercial, public Internet 'wiki' site operated by OdioWorks. Last year, BluWiki users began a discussion about making some Apple iPods and iPhones interoperate with software other than Apple's iTunes. Apple lawyers demanded removal of the content (pdf) sending a letter to OdioWorks, alleging that the discussions constituted copyright infringement and a violation of the DMCA's prohibition on circumventing copy protection measures. Fearing legal action by Apple, OdioWorks took down the discussions from the BluWiki site but has now filed a lawsuit to vindicate its right to restore those discussions (pdf) and seeking a declaratory judgment that the discussions do not violate any of the DMCA's anti-circumvention provisions, and do not infringe any copyrights owned by Apple. 'I take the free speech rights of BluWiki users seriously,' said Sam Odio, owner of OdioWorks. 'Companies like Apple should not be able to censor online discussions by making baseless legal threats against services like BluWiki that host the discussions.'" Random BedHead Ed adds ZDNet quotes EFF's Fred von Lohmann, who says that this is an issue of censorship. 'Wikis and other community sites are home to many vibrant discussions among hobbyists and tinkerers. It's legal to engage in reverse engineering in order to create a competing product, it's legal to talk about reverse engineering, and it's legal for a public wiki to host those discussions.'"

CWmike writes "Advanced Micro Devices on Thursday introduced the latest member of its Phenom II X4 family of high-performance quad-core CPUs, which the No. 2 chip maker said it had run as fast as 7 GHz in extreme overclocking tests. Out of the box, the new X4 955 Black Edition, which is aimed at gamers and hobbyists, runs at 3.2 GHz, giving it similar performance to Intel's fastest desktop chips at lower cost, AMD says. The company was able to more than double the CPU's speed during its tests using extreme cooling technology that is not safe at home, said Brent Barry, an AMD product manager. The Web site Ripping.org notes that hobbyists with early access to the X4 955 chip have been able to clock it at up to 6.7 GHz. AMD said the chip was safe with fan cooling at up to 3.8 GHz."

An anonymous reader writes "Researchers at the University of Southern Denmark have modified a Wiimote so that it can control an industrial lawn mower. The project is called Casmobot (Computer Assisted Slope Mowing Robot). 'The Casmobot project is about making grass cutting more efficient,' said Kjeld Jensen, a robotics researcher at the University of Southern Denmark who developed the system. It uses a standard Wiimote that communicates via Bluetooth to a computer and robotics module built into the mower. Actions of the mower are matched to tilt actions of the remote. For example, if you tilt the remote down the mower moves forwards; tilt it up, and it moves backwards, and so on. The Wiimote can be used to control the mower manually or in computer-assisted mode, where the mower uses autonomous navgiation based on RTK GPS positioning to cut larger areas."

An anonymous reader writes "Yesterday iFixit tore apart the Nintendo DSi and found several internal upgrades from the outgoing DS Lite. It seems that an experienced hand can completely disassemble the DSi in less than ten minutes using standard tools, especially since the job does not require a tri-wing screwdriver. This should make repairing and tinkering with the DSi substantially easier. The DSi now includes two integrated cameras that, unfortunately, have only 0.3 megapixel resolution. This is certainly a bit underwhelming considering most mainstream phones have cameras of at least 1.3 megapixels. As for chips, Nintendo is using a Samsung MoviNAND integrated 256 MB Flash memory / MMC controller chip, as well as a custom ARM CPU + GPU is stamped with the revision code 'TWL.' The DSi's chips all had manufacture dates around September 2008, indicating that Nintendo has been stockpiling these devices for quite a while prior to the North American release."
