Wave Bubble Portable RF Jammer


Hack-A-Day friend [Limor] AKA [ladyada] has been promising a portable RF jammer for a while. guess what she sent me for Christmas? The Wave-bubble is a self tuning RF jammer – good for around 20 feet of RF enforced peace. (It outputs .1-.3 watts) With a pair of less efficient antennas, it even fits inside a pack of cigarettes. She’ll never sell these because the FCC would come-a-knockin, but if you’ve got some major skills, you might be able to build one. (I’m going to believe her take on this, I’ve seen her work in person and it’s some damn fine stuff)

Merry Christmas! Get your Design Challenge entries in today!

Wireless Card = ARM Development Platform


[Archantos] sent us this one. The mustumbler project is actually trying to use some external hardware to make a miniature wireless stumbler. [Archantos] points out that it’s could be a cheap way to get your hands on an ARM development platform. He’s right. Just a few connections gets access to the I2C bus, a GPIO expander for I2C runs the LCD and an EEPROM is there for program storage. The software is still being sorted out, but the hardware itself is functional. If they can manage to reverse engineer the Conexant chipset, they should have a very promising platform.

WiCrawl – Next-gen WiFi Auditor


At ToorCon, our friends at Midnight Research Labs released a new automated WiFi auditing tool called WiCrawl. WiCrawl automatically scans for accesspoints. Once an AP is discovered a number of plugins can be run against it ranging from getting an IP to breaking encryption. Aaron Peterson’s talk and demo is 50mins. You can download the 640×480 170MB .mov version here. The tool is going to be included in the next BackTrack CD.

Steerable Cantenna

I almost passed over this one, since it’s another cantenna. With the software the Adrian wrote, it’s a fully functional directional wifi scanner. The system can pan and scan a region and visualize the results. Scan resolution can be varied, similar to a regular image scanner. It’s built from a pair of stepper motors ,a PIC on a SIMM stick with a serial interface.

USB WiFi External Antenna

[ronobvious] purchased a Ralink based USB WiFi adapter for use with Aircrack-ng. It worked well so he decided to add an external antenna connector. The connector from Linx Technologies that he chose is really what makes this installation clean. It’s a card-edge design so you just slip it over the end and solder the pin and ground leg. He’s got a link to Tobias Hain’s similar mod and Tobias has a link to a another antenna project as well.
