Hack a Day
[Jason Wright] and [Jeremy Blum] are showing off the project they developed for their Designing with Microcontrollers course at Cornell University. They call it the Heliowatcher, and if you know your Greek mythology we’d be you figured out this watches the movement of the sun and adjust a solar panel to follow it. Their design is simple [...]

3D printers are very popular right now. We’ve seen them go from an interesting project to multiple commercial entities. Makerbot seems to be the poster child for the commercial side of things, at least they were. Their former COO [Samuel Cervantes] is now in charge of a new company called Solidoodle. Their main product is [...]

Here are the contronl modules for a sous-vide project over at Nerdkits. [Humberto] and crew continue doing a great job of focusing a project on one goal, then explaining the steps needed to get there. In this case they wanted to build their own sous-vide appliance that was cheap, and didn’t really require the user [...]

So you’ve got a really cool project that requires a wireless controller and a ton of different channels. What are you going to do? Are you going to go pick up an expensive RC controller? Nah, you’re going to build your own. This project makes a generic 20 channel controller for your projects by stuffing [...]

For his senior design project at Swarthmore College, [Julian] decided to build a metalworking equivalent to the RepRap. [Julian]‘s final project is a self-replicating milling machine, and hopefully giving some serious metalworking power to all the makers with CNC routers and RepRaps out there. At first glance, [Julian]‘s mill doesn’t look like something you would find [...]

[Bruce] sent us another fantastic final project from the ECE4760 class at Cornell. What you see above is an array of 36 near infra red LEDs shining into this young man’s brain for the purpose of spectroscopy. Light bounces back differently based on brain activity (blood flow). For this project, they are mapping their motor [...]

Here’s an oldie but a goodie: [Eiki], [Mark], and [Sheraz] built a pipe crawling robot for their senior engineering project at Florida Atlantic University way back in 2004. Despite being a rather old build, its aged well and still demonstrates the clever ways the guys overcame some engineering obstacles. The original plan for the pipe [...]

[Roy] is getting to the end of his second CNC mill project and finally seeing some results. Here you can see a bear he milled in some floural foam. The project started out as an Arduino-based pen plotter. It move the pen along one axis, and the drawing surface along another, with the third axis [...]

You know who thinks building a robotic octopus is an awesome idea? EVERYONE. Apparently the idea is a solid enough idea that the European Commision has funded this project. The goal is to mimic the capabilities of the squishiest of the cephalopods in order to advance soft robotics. Or possibly to take over the world. [...]

Packet Storm Security Advisories
Asterisk Project Security Advisory - In the Skinny channel driver, KEYPAD_BUTTON_MESSAGE events are queued for processing in a buffer allocated on the heap, where each DTMF value that is received is placed on the end of the buffer. Since the length of the buffer is never checked, an attacker could send sufficient KEYPAD_BUTTON_MESSAGE events such that the buffer is overrun.

cracking FPGA Event:
Chaos Communication Congress 27th (27C3) 2010 Abstract: In 1998, the EFF built "Deep Crack", a machine designed to perform a walk over DES's 56-bit keyspace in nine days, for $250.000. With today's FPGA technology, a cost decrease of 25x can be achieved, as the copacobana project has shown. If that's still too much, two approaches should be considered: Recycling hardware and distributed computing. This talk will be about combining both approaches for the greater good. A number of projects (Copacobana, Picocomputing) have shown that with today's technology enough brute force computing power to break limited keylength ciphers (like DES) is affordable even for small companies. But what about Joe Geek at home? Recycling FPGAs is one option (nsa@home), distributed computing another (distributed.net, ...). This project combines both approaches, developing a toolchain that can be used to prototype a project on a low-end FPGA (or even in a free simulator), and then scaling up the effort across different implementations onto a large number of devices. An example client implementation uses an FPGA in a widely available consumer device to provide computing power when the device is in standby. Another approach that will be discussed in detail is how to obtain decommissioned high-end FPGA-based hardware. We will have hardware to show with a live demo!

You’re going to want to do some stretching before undertaking a soldering project like this one. We’re betting that the physical toll of assembling this 4-bit discrete processor project is starting to drive [SV3ORA] just a bit crazy. This small piece of electronic real estate is playing host to 62 transistors so far, and he’s not [...]

Chaos Communication Congress 28th (28C3) 2011 Abstract: This talk will be about the WhiteIT project, initiated by Mr Schünemann, German Minister of Interior in the state of Lower Saxony. The WhiteIT project is concerned with combating the online-distribution of child abuse material. WhiteIT tries to develop tools and processes to cooperatively suppress the disemination and (re-)distribution of said material. During the Talk the lecturer will try to encourage some open source intelligence. So please consider bringing a laptop, netbook or tablet with you to help gather and collect certain informations right away. Being involved with the WhiteIT project, the lecturer will use this opportunity to speak freely about his concerns regarding certain aspects of the endeavour. The talk will try to explain some of the projects aims as well as technical tools and processes developed and why he thinks this also concerns you as well. Although the talk will mainly be concerned with WhiteIT and its members, it will also be of concern for other nationals as there are some global players involved. The Talk will be somewhat interactive asking you to crowdsource certain information that the lecturer could not get hold off, so please bring a laptop, netbook or tablet with you to be able access a wiki/etherpad.

Asterisk Project Security Advisory - It is possible to enumerate SIP usernames when the general and user/peer NAT settings differ in whether to respond to the port a request is sent from or the port listed for responses in the Via header. In 1.4 and 1.6.2, this would mean if one setting was nat=yes or nat=route and the other was either nat=no or nat=never. In 1.8 and 10, this would mean when one was nat=force_rport or nat=yes and the other was nat=no or nat=comedia.

Packet Storm Security Tools
iExploder is like a fire hydrant full of bad HTML and CSS code to test the stability and security of web browsers. Available as a standalone webserver or CGI script, it continuously feeds browsers bad data in the hope that they will eventually crash. It is designed to run for hours, or even days until the browser crashes. namebench was initially written as a QA tool for the Mozilla Project to test the Firefox 1.0 release, and is now included and used by Apple's Webkit project.

Hack a Day
[Aaron] calls this project “Stochasticity”. It uses two sponges as a musical interface. The performer wears a wrist strap and then draws on the table with water from the sponge to play different notes. You really need to watch the video to fully understand what’s going on here.
We’re guessing that this is Arduino based since [...]

Hack a Day
Here’s a USB oscilloscope project from a few years back. It’s easy to build on a single-sided PCB and very cheap because it uses just a handful of parts. At the center, an ATtiny45 microcontroller uses its ADC capabilities for the two traces and also handles the USB connectivity. The internal oscillator is used and [...]

Hack a Day
Buy stock in hot glue, this project corners the market on the stuff. [Leafcutter John] uses the hot goop as his water-proofer of choice when building an underwater microphone (also known as a hydrophone). By installing a couple of piezo elements on one lid of a tin can he is able to record some amazingly [...]

Packet Storm Security Misc. Files
strongSwan is a complete IPsec and IKEv1 implementation for Linux 2.4 and 2.6 kernels. It interoperates with most other IPsec-based VPN products. It is a descendant of the discontinued FreeS/WAN project. The focus of the strongSwan project is on strong authentication mechanisms using X.509 public key certificates and optional secure storage of private keys on smartcards through a standardized PKCS#11 interface. A unique feature is the use of X.509 attribute certificates to implement advanced access control schemes based on group memberships.
