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…

It’s only been a week since the Super Gameboy’s boot ROM was dumped by [Costis] and he’s already at it again. This time he’s managed to grab the Gameboy Color’s boot ROM. He found the newer Gameboy Color’s hardware is able to cope with a clock speed up to 100MHz, so the original clock increase trick he used on the Super Gameboy wouldn’t work again.
Instead he discovered a quick disconnection of clock and power before 0xFF50 would make the Gameboy jump to a random area within the ROM. Then it was only a matter of entropy, luck, and…

Apple now has the support of a USB industry standards group in its battle to keep the Palm Pre from using the iTunes music service.The USB Implementers Forum (USB-IF) said in a statement Tuesday that Apple can block the Pre from connecting to iTunes. The group issued a letter to both companies warning Palm that further attempts to use iTunes would violate the group’s policy.The voice of the USB-IF is strong in this case since the group is responsible for issuing Apple the hardware vendor ID that lets its devices connect to iTunes via USB. Palm has used this process…

[Jon] wanted to have some fun with the Graffiti Research Lab’s LASER Tag. Unfortunately his computer wasn’t quite up for the challenge of detecting the laser pointer with a webcam. Not to be discouraged by this hardware limitation, he purchased a used Wacom tablet and threw together some code to make it work with the GRL display software. Now designs can be scrawled on the pad and the projector displays them with the familiar dripping paint effect.

Our friends over at ifixit are at it again, how they get these devices so early before release and make a complete teardown in time still amazes us. Today they bring us the latest Microsoft media device, the Zune HD. Some features worth mentioning: The astoundingly thin, 1mm we’re talking, OLED screen. The Nvidia Tegra 2600 processor, hinting at 3D game capability. And finally who could forget the 660 mAh battery. But isn’t that 129 mAh less than the iPod touch? Microsoft’s reply, supposedly the Zune HD is using many more low power hardware solutions in this device. Either…

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…
