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 […]
Radioactivity stirs up a lot of anxiety, partially because ionizing radiation is undetectable by any of the senses we were born with. Anytime radiation makes the news, there is a surge of people worried about their exposure levels and a lack of quick and accurate answers. Doctors are flooded with calls, detection devices become scarce, […]
At the risk of putting too fine a point on it, Hackaday exists because people are out there building and documenting open source gadgets. If the person who built a particular gizmo is willing to show the world how they did it, consider us interested. Since you’re reading this, we’ll assume you are as well. […]
If IKEA made ball-balancing PID robots, they’d probably look like this one. This [Johan Link] build isn’t just about style. A look under the hood reveals not the standard, off-the-shelf microcontroller development board you might expect. Instead, [Johan] designed and built his own board with an ATmega32 to run the three servos that control the […]
The Jacob’s Ladder is an electrical device named after a biblical “ladder to Heaven”, consisting of a pair of vertically oriented conductors that spread apart vertically. These conductors are charged with high voltage, which creates the repeatedly climbing arc we’ve all come to know and love from science fiction movies of yesteryear. [LOOK MUM NO […]
[Federico Tobon] from [Wolfcat Workshop] spent Makevember in 2017 building a series of fascinating automata using the most basic of craft supplies and simple tools in his workshop. Using a combination of rigid materials such as wooden cubes, popsicle sticks, and paper clips and pliable ones like paper and rubber bands, his creations are way more delightful to […]
Most of us have our fair share of digital debris. After all, with drives measured in one-million-million byte increments it’s tempting to never delete anything. The downside is you may never be able to find anything either. [Johnny Noble] must have gotten pretty fed up with clutter when he decided to formalize and publish his […]
