Hack a Day
The work which [Mark] did to mount this iPad mini in the dashboard of his Ford truck is commendable. It looks like it came from the factory this way, and the functionality matches that illusion. He actually started the project before he had the iPad mini on hand. A PDF that mapped out the exact [...]

Never one to pass up the recycle pile at work, [Scott] usually doesn’t find much. A few old hard drives, maybe a ancient laptop every once in a while, but on very rare occasions he finds something actually useful. This latest haul is a gaggle of stepper motor drivers that, with a bit of work, can [...]

[Andrew Gibiansky] has just started a tutorial series called Computing with Transistors. It’s purpose is to pull back the many veiled layers between high level languages and the controlling of electrons. And fittingly this first post starts off by explaining voltage source, load, and current. Don’t be thrown by its simplicity though. [Andrew] quickly moves [...]

Making computers interact with physical objects is a favorite of the HCI gurus out there, but these builds usually take the form of image recognition of barcodes or colors. Of course there are new near field communication builds coming down the pipe, but [Andrea Bianchi] has figured out an easier way to provide a physical [...]

[Brendan Sleight] has been hard at work on this wearable piece of tech. He doesn’t wear much jewelry, but a wedding ring and some cufflinks are part of his look. To add some geek he designed a set of cufflinks that function like traffic lights. Since he still had some program space left he also [...]

Chaos Communication Congress 21th (21C3) 2004 Abstract: We will present the state of the art in deployed anonymous communication systems, and in particular Mixminion, for anonymous email, and Tor, for anonymous web browsing. We will focus on the concrete future challenges to deploy and strengthen theses systems. In the last few years there has been a renewed interest in anonymous communications, both in terms of accademic work but most importantly in terms of implemented and deployed systems. This talk will be geared towards those at the cross section of practice and reaserch that are interested in developing or strengthening applications that provide some anonymity protection. We will describe two systems that are based on solid theoretical work, and should provide a high degree of security: Mixminion, is a high latency remailer, that can be used to anonymise email, while Tor is a low latency Onion Router, supporting the transport of any TCP stream. The two architectures are complementary, and provide very different security properties. While deployed, for testing, they Mixminion and Tor are both works in progress, and many practical as well as research challenges need to be resolved before they become widely used. The talk will first give an overview of Mixminion and Tor, highlight their architectural similarities and differences. Some attention will be paid to the threat models that they try to protect against and the features that they provide. The key attack techniques will be presented, but without going into the mathematical details. Pointers for further reading will be provided for those who are keen. Then we shall focus on the issues that remain to be resolved to widely deploy these systems, and further strengthen them. These issues are both research questions or concern the practical implemetation of anonymous infrastructure and services. On the one hand there is a need to build more services merely to support anonymous communications: from the implementation of pseudonym servers, directory services, or integration into client applications to research on DoS prevention and flooding. On the other hand the communication infrastructure is only there to be used by higher level applications. Therefore there is a need to understand which applications can be used without modifications over anonymous communications, and which will require to be modified not to compromise identity information. As a result of this talk participants should feel confortable with the basic design of anonymity systems, and know where to find additional information to use or build on these systems. If they choose to further look into the subject they will know what the main issues are where more work is required, and know the venues where this work can be presented, used, and appreciated.

We don’t know if it’s a mid-life crisis or just the result of way too many solder fumes, but [sparten11] on Instructables is building one of the coolest robotic arm we’ve ever seen, and we thank him for that. The build began with a set of brushed DC motors running capable of running on 60 [...]

The robotic bartender, lovingly named the Inebriator, is a work of mastery. We think you’ll be surprised by the simplicity and grace of its beverage dispensing system. The most obvious part is the lineup of nine liquor bottles across the top with LED backlight for style. Each has a valve on it that is meant to [...]

Chaos Communication Congress 23th (23C3) 2006 Abstract: EFF staffers answer your questions about American wiretapping, the latest moves of the *AA, the spread of the DMCA through free trade agreements, what's up at WIPO, and other dispatches from the US and elsewhere. This panel will take a loose question and answer format after a brief (and entertaining) summary of EFF's work and investigations this year. They will be representatives of all three aspects of the non-profits work: activism, technological research and US legal actions. The emphasis will be on the international aspects of the EFF's work (including their representation at WIPO, and work on various free trade agreements and European standards bodies), but we can also go into some detail on many of the domestic US work, as well as the ramifications of the recent US elections, and prospects and threats to digital freedom in the future.

The 1970s were the glory days for analog synthesizers, and for [Stefan] listening to huge modular Moogs and ARPs resulted in a wondrous seething jealousy. In 2009, wanting to relive just a little bit of his childhood, [Stefan] picked up a PAiA Stringz’n'Things from eBay. It’s a great little keyboard, but [Stefan] his new purchase to look [...]
