I hear often that it is hard to practice/demo voice related configurations with GNS3. This is only partially true.
It is correct that GNS3 cannot substitute Multiservice routers like 28xx etc because the DSP resources cannot be emulated. For using T1/E1 or FXS/FXO connections you need the real hardware interfaces and of course another PBX/router interface to connect your T1 to. If you have a double T1 you could use a T1 x-over to let the router do both ends.
For all other configurations like Dial-peers, translation patterns, SIP-UA configurations, CME, ephone registrations, CUBE etc, GNS3 can do the job. Just an example…

Spoof shows turn tables on celebrity obsession
LOS ANGELES (Reuters) – Watch out Britney, Octomom and Paris!

Steal the administrator password from an EEPROM
Did you forget your hardware-based password and now you’re locked out? If it’s an IBM ThinkPad you may be in luck but it involves a bit more than just removing the backup battery. SoDoItYourself has an article detailing the retrieval of password data from an EEPROM.
The process is a fun one. Disassemble your laptop. Build a serial interface and solder it to the EEPROM chip where the password is stored. Connect this interface to a second computer and use it to dump the data into a file. Download a special program to decipher the dump file and dig…

Facebook Releases Developer Tool To Stress Test Connect Implementations
Earlier this week, Facebook announced a new tool for developers to enable them to test new implementations of Facebook Connect and to ensure that the service is always running. The tool leverages Waitr, an open-sourced Ruby library for automating internet browsers. It will automatically run browsers for you and provides an interface for quickly navigating and interacting with a web page’s various components. The point is to ensure that Facebook Connect is always working.
Funny enough, I tested out StreamDiff, a Connect-enabled application that was tested with this new tool but I couldn’t get through the entire authentication process. Regardless…

Hacking USB serial port adapters
The folks at Openschemes.com have written up an article on how to convert a USB serial port adapter to a low voltage serial interface for interfacing with microcontrollers. Though you can always just buy one, this is a fairly quick and cheap solution, especially if you are in a pinch or don’t have access to a retailer. The specific models you should watch for, are the ones with two chips, a microcontroller and a line translater.They go through the process of finding exactly where to patch in to add an extra interface. It only takes a couple wires and…

Virtual pool, real-world interface
Sunday we saw robots playing pool and an augmented reality pool game. Today we’ll complete the pool trifecta: virtual pool using a real cue stick and ball in another vintage video from Hack a Day’s secret underground vault. The video is noteworthy for a couple of reasons:
First is the year it was made: 1990. There’s been much buzz lately over real-world gaming interfaces like the Nintendo Wii motion controller or Microsoft’s Project Natal. Here we’re seeing a much simpler but very effective physical interface nearly twenty years prior.
Second: the middle section of the video reveals the trick behind it all, and it turns out…

Web controlled Dark Crystal
[Reza] sent in his mood rock. Unlike other “mood” devices, instead of showing what mood you’re in, it shows what mood the internets are in. Two ShiftBrite modules are controlled by an AVR ATmega8 which then connects to a computer via USB. The assembly is placed inside of a piece of alabaster.
USB communications are controlled by the ATmega8 running V-USB (formerly AVR-USB) firmware. [Reza] wrote some code to control the colors from the web using Perl and AJAX. Head over to the web interface to set the colors yourself. We’d love it if a live webcam was added…

EDuino – Arduino or AVR breakout?
We’ve had a lot of requests in the comments for more Arduino centered posts so we were happy when [Njay] told us about his EDuino board. This is a minimal Arduino clone that has a crystal and it’s capacitors, a pull-up resistor and button on the reset pin, and a detachable serial programming connection. He also has a breadboard-friendly version seen above with all the interface pins on one side of the board. This is certainly a useful project and we’re glad to see the board files available for download. This does get us thinking… is this an Arduino,…

Using MatchBox cars as a switch
[atduskgreg] posted this interesting setup to flickr. He’s using two toy cars as a switch. He has wired into their metal undercarriages so when they collide, the circuit closes. We’ve seen some pretty nifty home made interface items, but usually they are posted with a clear purpose or a project. This one is a little puzzling. Does he intend to keep using the cars or was he just fooling around? Is he working on a toy that does something when they crash? Was he merely bored and wanted to see what he could attach to his Arduino. We may…

Bar2d2 on the Discovery channel
The friendly robotic bartender we’ve covered a couple of times before hit the airwaves last week. [Jamie], the inventor of Bar2d2 sent in a link to video of the barkeeper in action. The story runs from 0:30-4:40 and covers a bit about the build, the conversion to automatic drink mixing, and plenty of happy liquor-guzzling party goers.
We get a good look at the drink ordering interface called Lazy Drinker. It runs on a laptop and communicates wirelessly with Bar2d2. Looks like you can get your hands on the software for free but the hardware, either in kit form…
