Ask Slashdot: Calculators With 1-2-3 Number Pads? 393

Posted by timothy from the count-backwards-divide-by-zero dept.
dotancohen writes "Although the telephone has the 1-2-3 key on the top row, most calculators and keyboards have 7-8-9 on the top row. Switching between the two destroys muscle- and spatial- memory. Do any slashdotters use a scientific calculator with 1-2-3 on the top row? I've already scraped and resoldered my Casio fx-82 calculator to have 1-2-3 on the top, and remapped the numpad in Kubuntu, but if there exist any calculators like this already on the market, I'd buy two."

Opportunities From the Twilight of Moore's Law 148

Posted by timothy from the finest-corinthian-leather dept.
saccade.com writes "Andrew 'bunnie' Huang just posted an excellent essay, Why the Best Days of Open Hardware are Yet to Come. He shows how the gradually slowing pace of semiconductor density actually may create many new opportunities for smaller scale innovators and entrepreneurs. It's based on a talk presented at the 2011 Open Hardware Summit. Are we entering an age of heirloom laptops and artisan engineering?"

An $80 Open Source Chemical Analyzer 51

Posted by Soulskill from the great-for-perfecting-that-chili-recipe dept.
An anonymous reader writes "A group of electrical engineering students at UCSB teamed up with some chemists and built an $80 gadget that can check water for arsenic, measure the level of vitamin C in orange juice, and also do simple DNA biosensor tests. The electronics in a blood sugar meter could do all of those things, but their firmware isn't easily hackable. All of the circuit schematics, gerber files, and software for this project are available on their project website. Another team at Denver Metro College is working to improve upon their design. Eventually, it could be used as a teaching tool in chemistry classrooms, or possibly to do blood and water tests in developing countries."

Boost Your Wi-Fi Signal Using Only a Beer Can 229

Posted by timothy from the for-some-values-of-only dept.
First time accepted submitter AmyVernon writes with a small hack that "is supposed to boost signal strength by at least 2 to 4 bars," and which requires little more than a can of beer (or Orangina). She writes: "What you need: scissors, a utility knife, some adhesive putty and an empty beer can. The brand doesn't matter for the router, but I suppose it would be cooler looking if it were Asahi or Stella Artois than if it were Budweiser." Perhaps this will be added one day to my favorite (and very extensive!) list of low-budget Wi-Fi amplifying rigs.

Heathkit DIY Kits Are Coming Back 197

Posted by timothy from the golden-age-returns dept.
donberryman writes "IEEE Times reports that Heathkit, the fabled electronics kits company, is going back into that business after a two-decade hiatus. The Heathkit website says that they will be releasing Garage Parking Assistant kit (GPA-100) in late September followed by a Wireless Swimming Pool Monitor kit. Amateur radio kits may be coming by the end of the year." I hope for real this time — I never saw for sale the HERO kit they promised a few years ago.

Xbox 360 Reset Hack Yields Unsigned Code Execution 177

Posted by Soulskill from the let's-see-if-microsoft-pulls-a-sony dept.
walshy007 writes "A new exploit has been shown which allows unsigned code execution on the Xbox 360 for all current models. It functions by pulsing the reset pin at a critical time during the checksumming/crypto boot process. The exploit enables the running of Xell, a boot loader which facilitates the running of Linux, amongst other programs."

CyanogenMod Shows Off Android On the HP TouchPad 117

Posted by Soulskill from the that-was-fast dept.
adeelarshad82 writes "While a $99 TouchPad running webOS is a pretty good deal on its own, most of us got it hoping developers would eventually figure out how to run Android on it. And though we were warned against wandering off to the darker side, it seems the developers behind CyanogenMod wanted the device to boldly go where no TouchPad has gone before. In a video demonstration, they show off a very early version of its software running Android 2.3.5 on a TouchPad."

Right-Wing German Extremists Tricked By Trojan Shirts 457

Posted by samzenpus from the rinse-relax-repeat dept.
gzipped_tar writes "Fans at a recent right-wing extremist rock festival in Germany thought they were getting free T-shirts that reflected their nationalistic worldview. But after the garment's first wash they discovered otherwise. The original image rinsed away to reveal a hidden message from an activist group. It reads: 'If your T-shirt can do it, so can you. We'll help to free you from right-wing extremism.'"

Guide To Building a Cable That Improves iOS Exploits 184

Posted by timothy from the slurping-assistant dept.
mask.of.sanity writes "An Aussie network engineer has published a guide to building a serial cable connector that allows access to a secret kernel debugger hidden within Apple iOS. The debugger was a dormant iOS feature carried over from Apple OS, and seems to serves no function other than to allow hackers to build better exploits. The cable needs an external power source and a jailbroken device to access the debugger." We've mentioned Pollock's serial adapter kit before, modulo the kernel debugging abilities.

Build Your Own Camera, Launch It Like a Grenade 117

angry tapir writes "Meet the Firefly. Israeli defense contractor Rafael Armament Development Authority calls it a 'revolutionary concept in tactical intelligence,' but really it's a wireless camera that's shot 500 feet in the air by a grenade launcher. And if a couple of hackers at the Defcon hacking convention get their way, soon anyone will be able to buy this type of military grade technology for only US$500."

Autodesk + Instructables: For Makers? 77

Posted by timothy from the interesting-bedfellows dept.
ptorrone writes "MAKE magazine has published an in-depth look at what the recent acquisition of Instructables by Autodesk means for makers and the DIY movement. MAKE suggests it wasn't about getting the millions of members or projects at Instructables or upselling Autodesk tools. Instead, the acquisition was more about creating many Instructable-like communities around Autodesk's new free and trial tools including their 3D printing site and service, Autodesk123D."

.NET Gadgeteer — Microsoft's Arduino Killer? 241

Posted by Soulskill from the didn't-see-this-in-the-magic-eight-ball dept.
mikejuk writes ".NET Gadgeteer is a new open source platform, from Microsoft Research, based on the use of the .NET Micro Framework. It brings with it lots of hardware modules that are backed by object oriented software. You simply buy the modules you need — switches, GPS, WiFi etc — that you need and plug them together. The software, based on C#, is also open source, and comes with classes that let you use the modules without having to go 'low level.' Is this a competitor for the Arduino?"

Seigniorage Hack Could Resolve Debt Limit Crisis 696

Posted by Soulskill from the or-we-could-just-argue-more dept.
UltraOne writes "With the US Senate voting to table the Boehner debt limit bill, the US is only a few days away from running out of cash to pay for all its obligations. Slate is reporting on a fascinating legal hack that could come in handy, described by blogger 'beowulf' back in January 2011. Seigniorage is the extra value added when a government mints a coin with a face value greater than the value of the precious metal contained in the coin. The statute governing the minting of coins contains a section (31 USC 5112(k) ) that authorizes the Secretary of the Treasury to mint and issue platinum coins in any denomination or quantity. To keep the government from running out of money, Timothy Geithner could order a $5 trillion platinum coin struck and deposited at the Federal Reserve. The money could then be used to fund Federal Government operations (blog post contains legal details)."

'It turned out to be quite an odyssey, with twists and turns I describe here in order to help those who wish to embark on a similar journey,' Yegulalp writes. 'Was it worth the trouble? Yes, in the sense that learning how to jailbreak your own phone is a valuable skill, and I got much more functionality out of the Cliq, when I was expecting to simply junk it. '"

Japanese Military Invents Tumbling, Flying Sphere 156

Posted by Soulskill from the didn't-darth-vader-have-one-of-these dept.
thebchuckster writes "A Japanese developer has released a cool, new sphere that is billed as being able to go where humans can't. The sphere is 17-inches, features eight movable rudders, and can hover in the air for at least eight minutes. While reaching speeds of up to 37 miles per hour, the sphere deftly moves through the air without much effort. It doesn't take much to get it up in the air and moving, and it will be adept at going into tight areas."
