Defcon 15: WiCrawl From Midnight Research Labs

August 4, 2007 by 2 Comments


[Aaron] gave the latest on WiCrawl. The focus has been on the UI and usefulness for penetration testing. It’s got support for [David]s coWPAtty FPGA WPA cracking accelerator and some UI improvements. Even better, you can grab the WiCrawl module to put on a BackTrack Slax livecd from the project page. [Aaron] passed out some CD’s at the talk – I’ll update if the ISO gets posted.

And yes, I think I finally recovered from playing Hacker Jeopardy on team MRL. We held our own, but lost on the (LAME) final jeopardy question.

SIP For The SMC WSKP100

July 31, 2007 by 2 Comments


[sprite_tm] made my morning by sending in his latest work. After opening up his new SMC WSKP100 (Skype wifi phone) to identify the hardware differences, he managed to shrink a flash image from the SMCWSP100 to fit on his new toy. Then he spent some time hacking the kernel from the former to work on his phone. The result? A SIP operational phone that’ll connect to his asterix server at half the price of SMC’s official SIP phone.

DIY Digital Voice Transceiver

June 14, 2007 by 12 Comments


[dk] sent in the DVX project. It’s a complete D-STAR implementation that’s built around a digital transceiver chip, an ATMEL mcu and a digital voice compression chip. Compared to most digital radio’s I’ve seen, this one is pretty simple. The really complex action lives in the main chips with a bunch of caps and resistors to support them. Watch out for Digikey’s pricing – it looks like a major gouge after looking at the tx/rx chips on Analog Device’s site. If you get them at a decent price, they could make great rf links for your projects. The link to the paper seems a bit broken, but here’s the correct one.

Wireless Reef Automation

June 1, 2007 by 5 Comments


I’m on a 1-wire/home automation kick lately. It looks like he’s giving up on the router platform, but [barebottoms] did some interesting work with a couple of wireless routers (a belkin that he fried, and then onto a wrt54g) to create automated controls for his reef. Think of it as home automation for the fishes. It’s an interesting idea – a hacked wireless router could make a fairly robust and power efficient controller for simple HA applications. His site isn’t really that informative, I found the forum posts more interesting.

I2c For The Fonera

May 28, 2007 by 5 Comments


La Fonera’s are getting pretty popular lately. [Lefinnois] hacked his to get i2c working. He used a 75LS05 to adapt the io levels, and some bit banging in the software to pull it off. Now the Fonera can be used for inexpensive remote monitoring via inexpensive i2c devices. Not to mention that this could provide a cheap network interface for various micro-controller projects. (I’m thinking networked thermostat for my new house.)
