Hack a Day
[Eric Gregori] sent in an article he wrote for EETimes to introduce the concepts behind computer vision to the masses. As a nice little bonus, [Eric] included a VMware image containing Ubuntu and all the packages and examples necessary to write your own OpenCV apps. There’s a ton of awesome stuff you can do with [...]

You know you’ve got a good hardware platform if you can easily repurpose it with a code rewrite. And that’s what [Eric] continues to do with these little Hexbugs. This time around he’s bent the IR emitter and receiver downward to use as a reflectance sensor. This gives it the ability to follow a dark [...]

[Josh] and his lab partner [Eric] needed a final project for their Embedded Systems Design class, and thought that designing an Arduino shield would be a cool idea. They noticed that there are plenty of ways to get an Arduino to keep time, though none that they knew of utilized WWVB (Atomic Time) signals directly. [...]

[Eric Gregori] had an OWI535 toy robotic arm. Although cheap (coming it at around $30) the arm is only set up to be used via a wired control box. [Eric] knew he could do better by adding computer control via a TI Launchpad and motor driver peripheral. The arm has shoulder, elbow, and wrist joints, [...]

Yes, the Kinect is over one year old now, and after some initial unhappiness from [Microsoft], it’s become a hacker’s best friend. [Eric] decided to celebrate this with an Article all about how it works. If you’re new to this piece of hardware and want to get into working with it, this should be a [...]

[Eric] sent in his tutorial on building a Kinect based robot for $500, a low-cost solution to a wife that thinks her husband spends too much on robots. For the base of his build, [Eric] used an iRobot Create, a derivative of the Roomba that is built exclusive for some hardware hackery. For command and [...]

To decorate the office for Halloween [Eric] decided to make [Vigo the Carpathian] stare at passersby. We hope that readers recognize this image, but for those younger hackers who don’t, this painting of [Vigo] played an important part in the classic film Ghostbusters II. In the movie, his eyes appeared to be following anyone looking at [...]

The answer, of course, is a word clock. This is actually [Eric's] second version of a word clock. Like the first one, it uses 114 LEDs to back light the words on the display. In his first iteration he used an Arduino to drive a Charlieplex array of lights. It was an 11 by 10 [...]

One of the first things that [Eric] hacked together when he got to college was an RFID door locking system. He found that he was often in a rush to get in and out of his dorm room, and that using a simple wireless key was a great way to streamline his days. Over the [...]

It’s officially September now (in some parts of the world), and that means we’ve been watching the Christmas decorations go up on the floor of Costco, Walmart and Target for the last few weeks. As a small test of reality, [Eric] decided to build an electronic advent calendar that counts down the days until Christmas. [...]

Hack a Day
[Eric] needed a project for his digital logic design class, and decided on a lock that open in response to a specific pattern of knocks. This is a fairly common project that we’ve seen a few builds with ‘knock locks,’ but this one doesn’t use a microcontroller. Instead, it uses individual logic chips. The lock [...]

[Eric] wanted to teach his kids Morse code, so he built a tiny Morse code trainer. [Eric] built the trainer around an ATtiny85, and the rest of the circuit follows this minimalist idea. After connecting a piezo beeper and 6-pin ISP header, the only thing left to do was write a little code and start [...]

For those of you who are new to Buby, it is a platform to write Ruby based extensions for the Burp Suite API and I'm going to attempt to cover some of the basics. First let me say thank you to Tebo for providing his insight. Tebo is the author of the
Buby.kicks_ass => true article. Additionally, thank you Eric Monti the creator of Buby. Buby's homepage is located
Here .
Installing:
Although you can write Ruby code, this is a JRuby Gem. What does this mean? It means that the code execution environment is JRuby (Java+Ruby) and the Gem should be installed in the JRuby environment.
Lets install JRuby first:
Next, install the Buby Gem.
Basic example of running a script:
The options you see explained
jruby -S buby => runs the jruby environment leveraging the buby gem
-i => interactive, this means you can interact with Burp from the console.
-B => this is the location of your Burp jar file
-r => The script you'd like to run. This is an easy way to run the buby code you've created.
Finally, an example of sending a command to burp via the -i (interactive option). Here we produce an alert "Hello World".
Pre-command
Command
Post CommandOkay so that wraps up Part 1 of Buby Basics.
If you'd like some scripts to mess around before Part 2, you can find some scripts I put together
Here.
~Happy Hacking

There is nothing wrong with your television set. Do not attempt to adjust the picture. Where would we be if we listened to advice like that? [Eric] writes that with a fairly simple circuit, he’s able to split a composite video signal into its constituent X and Y ramp signals for display on his trusty [...]

[Eric] recently built an AM radio based on a 555 timer, and posted a few pictures to the Hack-a-Day Flickr pool. He used the 555 timer as an AM demodulator and power amplifier in order to drive the speaker. A hand-wound inductor is used to tune the signal which is then superimposed over the ramp [...]

[Eric] has a problem with his new house, there was no heat in the attic space that had been converted into a loft. Facing no way to tap into the ductwork and wanting to use the space as a bedroom he did what most of us would, and just got a little space heater. Anyone [...]

This clock concept uses big dominos with changing faces to display the time. As far as we can tell they haven’t made it through to a finished product yet, but we loved the explaination of the engineering that went into the prototype. After the break you can watch [Eric] explain how he accomplished the design [...]

[Eric Gregory] has gone a bit mad scientist on the Chumby, turning it into a bipedal bot. We expected all kinds of cool chumby hacking, but we can’t say we saw this one coming. [Eric] points out that with a 454Mhz processor, 64MB of RAM, 2GB of expandable storage and a USB host port, the [...]

Reader [Eric] sent us a powerfully informative, yet super simple hack for the MindFlex toy. Don’t worry, it’s not another worthless shock ‘game’, And it’s using an actual interface instead of the built-in LEDs.
With two wires for the serial protocol, and an Arduino, you’ll be able to view “signal strength, attention, meditation, delta, theta, low [...]

[Eric] built this robot for the 2009 Robocup Jr. competition. The game ball has IR LEDs inside of it and this little bot uses eight IR detectors for tracking. Four motors mounted perpendicular to each other provide locomotion. Since this would normally have you traveling in circles, he used some omnidirectional wheels walled Transwheels. As [...]

VPN darknet Event:
Chaos Communication Congress 26th (26C3) 2009 Abstract: Building a private network to connect your neighbourhood. Why we feel common solutions are terrible on resources and what we think is better. Get on board. This talk will give you the opportunity to take a look at the shades of grey of interconnecting hackerspaces and people's networks. Mc.Fly presents ChaosVPN, reborn in its darknet-ish approach and gaining momentum from established hackerspaces in the US and Europe with spaces like NYC Resistor, Pumping Station: One, Noisebridge and c-base. The Agora Network will be presented by Aestetix and Eric in covering the community and technical aspects and what to expect. Equinox will show you the white-ish side called dn42 - the old but nice lady that connects mostly german people and younger spaces like sublab and entropia. Leveraging the efforts of the ChaosVPN network in the US is the Agora Network (Currently In Private Beta). By doing this we are not having to duplicate the efforts of every one involved we have settled on a standard platform utilising tincd. With hackerspaces popping up very rapidly and successfully in the US for the last 24 months we find this necessary. Agora is a mesh vpn service that serves to tie them all together on a common intranet. On the network people will be hosting machines for VMs, development, file hosting, PBX phone services, and a number of high performance clusters at the disposal of users which we are currently developing including those provided by node users. In the process several universities in the US have asked to join the network for several research opportunities not previously available to them. dn42 is built with tunnels (OpenVPN, GRE, tinc, etc) and has BGP running over them - the same dynamic routing protocol the internet runs on, albeit with less networks in the routing table. We will shed some light on both the technical and social aspects of dn42. Our walk starts at technical foundations and heads over to what BGP allows us to do on a social level. We'll also see how the flow of traffic can be engineered according to external constraints (think your plain asymmetric DSL at home), and last but not least we'll discuss different cases of maliciousness and how they're treated. While dn42 is our playground for testing and modelling all this stuff, most of it apples to the internet as well. This talk is somewhere around entry to immediate level. You should roughly know what an IP subnet, a route and dynamic routing is.
