Join us on Wednesday at noon Pacific time for the high-altitude ballooning Hack Chat! The Cope brothers are our hosts this week. Jeremy, a computer engineer, and Jason, a mechanical engineer, have recently caught the high-altitude ballooning (HAB) bug. In their initial flights they’ve racked up some successes and pushed the edge of space with interesting […]
It may only run for a brief time, and it’s too big for use in an actual wristwatch, but this 3D-printed tourbillon is a great demonstration of the lengths watchmakers will go to to keep mechanical timepieces accurate. For those not familiar with tourbillons, [Kristina Panos] did a great overview of these mechanical marvels. Briefly, […]
The wheels of government move slowly, far slower than the pace at which modern technology is evolving. So it’s not uncommon for laws and regulations to significantly lag behind the technology they’re aimed at reigning in. This can lead to something of a “Wild West” situation, which could either be seen as a good or bad […]
RISC architecture is gonna change everything, and I still can’t tell if we like that movie ironically or not. Nevertheless, RISC-V chips are coming onto the market, chipmakers seem really interested in not paying licensing fees, and new hard drives are shipping with RISC-V cores. The latest development in Open instruction sets chips comes from […]
If you live in a bustling city and have anyone over who drives, it can be difficult for them to find parking. Maybe you have an assigned space, but they’re resigned to circling the block with an eagle eye. With those friends in mind, [Adam Geitgey] wrote a Python script that takes the video feed […]
Pianos are free, in case you’re not hip to the exciting world of musical instrument salvage. Yes, the home piano, once the pinnacle of upper middle class appreciation of the arts, is no longer. The piano your great aunt bought in 1963 is just taking up space, and it’s not like the guy on Craigslist […]
The Living Computers museum in Seattle has a Xerox Alto, the machine famous for being the first to sport a mouse-based windowing graphical user interface. They received it in working condition and put it in their exhibit, but were dismayed when a year later it ceased to operate. Some detective work revealed that the power […]
Once technology that was only available to expensive design teams, and high-end engineering work, 3D printers are now readily available to anyone. Designing a physical prototype with a 3D printer is now something anyone can afford. Did I say anyone? Yes, anyone, even the people trying to build perpetual motion machines. Here’s one on Kickstarter […]
We missed this Blackhat talk back in August, but it’s so good we’re glad to find out about it now. [Christopher Domas] details his obsession with hidden processor instructions, and how he discovered an intentional backdoor in certain x86 processors. These processors have a secondary RISC core, and an undocumented procedure to run code on […]
It’s been more than a year since we first heard about Leap Motion’s new, Open Source augmented reality headset. The first time around, we were surprised: the headset featured dual 1600×1440 LCDs, 120 Hz refresh rate, 100 degree FOV, and the entire thing would cost under $100 (in volume), with everything, from firmware to mechanical […]
