Hack a Day
Congratulations to [John Scancella] and his wife to be. Their recent engagement was aided by one of [John's] projects. Since [Betsy] is a big fan of Zelda, he thought it would be fun to present the ring with the Zelda music playing in the background. He and a friend combined forces to build what you [...]

Hack a Day
Here [Catarina Mota] is showing off a ring of magnetic ink printed on a piece of paper. It’s strong enough to hold a disc magnet in place when the paper is raised vertically. This strength comes from mixing your own batch of ink. Magnetic ink has been around a long time and is most often [...]

kernel exploiting Event:
Chaos Communication Congress 24th (24C3) 2007 Abstract: The process of exploiting kernel based vulnerabilities is one of the topics which have received more attention (and kindled more interest) among security researchers, coders and addicted. Due to the intrinsic complexity of the kernel, each exploit has been mostly a story on itself, and very little work has been done into finding a general modelization and presenting general exploiting approaches for at least some common categories of bugs. Moreover, the main target has usually been the Linux operating system on the x86 architecture. This talk reprises and continues the attempt done in this direction with the Phrack64 paper “Attacking the Core: Kernel Explotation Notes” that we released six months ago. A more in-depth discussion of some Solaris kernel issue (both on x86 and SPARC) and a more detailed analysis of Race Conditions will be presented.

Hack a Day
A lot of 3D printing and a many servo motors went into this snake-like robot, and it’s only about half of what [Toby Baumgartner] plans to accomplish. In this orientation the snake is rolled into a circle, and apparently some special movements in the segments allow it to roll around like this. He compares it [...]

security Event:
Chaos Communication Congress 27th (27C3) 2010 Abstract: The security model of our current computer architectures - kernel in ring 0, processes in ring 3 - goes back to the early 70s. However, science hasn't stopped. This talk is going to look into the state of the art in building secure computers, with a focus on type systems and formal verification, and hopefully an outlook on how tomorrow's computers will be more secure than what you can buy now.

kernel Event:
Black Hat USA 2010 Abstract: Getting to ring0 is the final step towards complete system compromise and can also be the most fun. In the course of one year, we have found around twenty kernel vulnerabilities, mostly in Windows and Linux, some of them being uncovered after ten or fifteen years of existence. We share some of this work and demonstrate some exploits, bugs and techniques.

Hack a Day
[Andrey Mikhalchuk] built his own magnetic levitation device and you can too… if you have the patience. He’s not using electromagnets, like the Arduino levitator or the floating globe. Instead, a pair of ceramic ring magnets and a few hours are all it takes. The base of his device is a couple of very large ring magnets [...]

Hack a Day
Instructables user [zvizvi] was working on putting together a portfolio for his application into Industrial Design school, and thought it would be neat to repurpose an old rotary phone that used to belong to his grandmother. He originally had pretty lofty goals for the phone, but eventually pared back his vision to include one-way communications [...]

DIY ring light setups for DSLR cameras are nothing new around here. While most of them rely on an array of LEDs or a mirror-based light tube, [Wolf] had a different idea. He figured that since optical fibers are made specifically for transmitting light from one place to another, they would make a perfect medium [...]

Hack a Day
It’s a nice touch to engrave a heartfelt message on a wedding band, and my couples choose to do so. But you can say a lot more with a 20 second audio message. That’s exactly what [Luke Jerram] did by etching an audio track into this ring. He uses his custom-built hardware to playback the [...]

Hack a Day
[Alan] acquired a stereo microscope from eBay, and decided to save some more money by designing, machining, and assembling his own arc reactor ring light to go along. After finding an LED driver board sitting around as well as ordering some surface mount LEDs, he set about using a lathe to cut away a block [...]
