Sometimes you absolutely need to keep your phone a secret. You know, like when you’re on spy missions. The goons at the door will always frisk you, but they never check under your shoe, right? [mikeyberman] shows us how to make our own Maxwell Smart style shoe phone. All you need is to dig a giant hole in your shoe sole and cram a cell phone in there. Will it get ruined by water? Probably. Will you look like a goon trying to talk on it? Definitely. Can you make it through airport security? Try it and let us know.

The Remote Exploit Development Team has just announced BackTrack 4 Beta. BackTrack is a Linux based LiveCD intended for security testing and we’ve been watching the project since the very early days. They say this new beta is both stable and usable. They’ve moved towards behaving like an actual distribution: it’s based on Debian core, they use Ubuntu software, and they’re running their own BackTrack repositories for future updates. There are a lot of new features, but the one we’re most interested in is the built in Pico card support. You can use the FPGAs to generate rainbow tables and do lookups for things like WPA, GSM, and Bluetooth cracking. BackTrack ISO and VMWare images are available here.

Many G1/ADP1 owners have been using the app Tetherbot to get internet access on their laptop via USB to the phone’s data connection. The app relied on the Android Debug Bridge to forward ports. It worked, but people wanted a solution better than a SOCKS proxy. The community figured out a way to create a properly NAT’d connection using iptables and then [moussam] rolled them up into easy to use applications. There’s one for setting up a PAN device on Bluetooth and another for adhoc WiFi networking. It requires you to have root on your phone, but hopefully you’ve achieved that and are already running the latest community firmware.

Here’s another video demo of [Eric]‘s Besmoke interactive fluid simulation that we covered earlier. It was put together for the BIL Conference last weekend. This time around he’s strapped the iPhone to his head (complying with California’s handsfree laws). To make things interesting, he’s also added OCZ’s Neural Impulse Actuator to provide brainwave input.

[Adam] sent us this cool game he made. It is accelerometer controlled pong (translated). The screen is a Nokia 3310 LCD, tied to an ATmega8 for the brains. He’s using an MMA7260 accelerometer for the controls. The whole thing is encased in an iPod nano box. this looks like a pretty fun little game, though we’d like to see someone attempt a two player match with it.

All bow your heads in reverence to the Ponginator. This bad boy is a performance robot, mounted to the end of a 3 story tall crane. He makes all kinds of noises, flashes all kinds of lights, and shoots ping pong balls at 170 miles an hour. This thing looks like it would be so much fun to play with. listen to it as he’s talking and you’ll pick out all kinds of Sci Fi sound effects, from Portal sounds to Star Trek sounds. Check out the second video on the site to actually see the Ponginator shooting.

Sony recently started to shipping the VAIO P don’t-call-it-a-netbook netbook. It comes stock with 2GB of RAM, which means it’s not eligible for Microsoft’s XP ultra low cost pc licensing. Hackers wanting to exorcise Vista have run into a few issues. After doing her unboxing photoshoot, [tnkgrl] wrote a guide for replacing Vista with XP on the Vaio P. She used the Universal Extractor to pop open the driver downloads and remove the Vista check. This got the WWAN radio and GPS working in XP. The only casualty was the volume and mute buttons are no longer working. You can see an annotated image verifying all the components here.

Notorious hacker conference Defcon has just published their Call for Papers. The 17th annual event will happen July 30th through August 2nd. Most of the announcement is the same boilerplate they’ve included for the past two years. Like last year, they’re not defining the specific speaking track themes and will come up with them based on submissions. New for this year is a half-day of workshops on the Thursday before Defcon for anyone that’s showing up early. This pre-con event is targeted at newbies. It certainly sounds like an interesting way to ease into Defcon instead of the usual delays and fire marshals. We’ve been attending every year since 2005 and love seeing new things. You should definitely consider presenting this year (we want to see more hardware!).
