[Eduard] was kind enough to pass along this airport express psu repair how-to (Translated version). The old Airport had those pesky capacitor issues. Apparently the power supply in the little buggers can have issues. The solution? Add a pile of voltage regulators and some smoothing caps to get things powered back up. No word on how the new PSU affects sound output.

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.
Bluetooth Roomba Phone Remote
He’s pimping his book a bit, but Tod sent in his hack for controlling his bluetooth roomba with a bluetooth phone. He released the bluetooth interface hack Now he”s whipped up a phone application that lets him fully control the roomba via bluetooth.
Floppy Connector MMC Card Slot
Rob Wentworth sent in his simple MMC card slot hack. He used that useless card edge floppy connector to add a MMC/SD card to his WRT54G. A quick rebuild and a spacer made it perfect connector. The connector meets the MMC pins perfectly, but skips the unneccesary SD contacts.
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.
