Ubiquity, a browser command line


During the last day the web has been abuzz about Mozilla Labs' Ubiquity. It's an addon for Firefox that can help you streamline how you get things done on the web. In the example above, they show constructing an email with a map and reviews using mostly keyboard driven input. The addon is quick to install and we think you'll find it saving you a lot of time on tasks you'd normally hit the search box for. In the popup, you can do quick Wikipedia lookups, define words, translate, perform calculations, and many other operations. You can email a page to someone by just typing three words. The best part is: anyone can write a command that will expand Ubiquity's function. Greasemonkey helped fix broken websites and we think Ubiquity will help make interactions between sites much easier. We can't wait to see what clever uses people come up with.

RC plane sequence caller


Reader [Kelly Regan] flies large scale RC planes, but would often need someone call out flight sequences while rehearsing. Not wanting to impose on fellow club members, [Kelly] built a sequencer caller from a cheap MP3 player. It just required extending the FWD key to a pin header. Those pins are connected to a custom switch on the back of the controller. Each maneuver is recorded with 30 seconds of padding and then added to a playlist. Once the maneuver is complete, a quick press of the button moves on to the next track. It's always nice to see people building devices that the consumer electronics industry probably wouldn't.

Coyote-1 guitar pedal available now


OpenStomp's Coyote-1 is now available for $349. The guitar effects pedal lets users design and upload their own effects to the device. It has two stomp switches with LEDs, an LCD display, and four user assignable knobs. The back has 1/4" in/out and one selectable 1/4". It also features NTSC composite out, a headphone jack, mini-USB for uploading, and an RJ11 I2C bus for expansion. The processor is a Parallax Propeller Chip. While the OS on the pedal is open source, the hardware design and effect design software are not. You can check out the source and product manual on their forum. If you're more interested in breadboarding hardware, you might like the Beavis Board we covered earlier.

Monster truck lawn mower


It's no secret that we're gear heads at heart. Our transportation hacks category is full of unfortunate machinery like [Steven Laurie]'s motor art, weed whacker bikes, and electric motorcycles of all types. Even we have trouble justifying the existence of this monster truck style lawn tractor though. We haven't found a project site for it and can't help but wonder what kind of person would build such a thing? It's obviously the type that would own a car sized American flag. We just need to realize with the popularity of lawn mower racing, this sort of thing was bound to happen.

James Powderly released


Graffiti Research Lab's [James Powderly] along with 9 other Tibet supporters were deported from China during the Olympic's closing ceremonies. Detained on the 19th, the activists were to serve a 10 day sentence, but the Chinese government buckled under international pressure and deported them early. This brings the total number of deported activists to 53 since the start of the games.

Graffiti Research Lab is well known for its laser tagging research.

Dan Kaminsky's DNS Black Hat video


Black Hat has published the media from Dan Kaminsky's infamous DNS vulnerability talk. You can get the full video (101MB) or just the audio.

The full archive of slides and white papers from this year has been posted too.

Wiimote head tracking in Processing


[Manuel] has been playing around with [Johnny Lee]'s Wiimote head tracking code. He's posted a preliminary port outlining the code in the Processing environment. It relies on darwiinremoteOSC so you won't see this outside of OSX, but it should help you out if you're trying to do this is in Processing on another platform.

SparkFun Arduino Pro


SparkFun's new Arduino Pro is an updated version of their Skinny. The board comes populated with the running gear of an Arduino, but without all of the connectors in place. It's targeted at people building integrated systems around the Arduino and not just prototyping. The board is 3.3V with an 8MHz bootloader just like the LilyPads and is fully certified by Arduino. It has a small side mounted power switch, but you have to supply your own DC jack (if you need it). There is no USB hardware on board and you're expected to program it via an FTDI breakout board or cable. We definitely like the stripped down approach, but it would have been nice if the price had dropped more.

Hack a Day t-shirt design contest update


We announced the Hack a Day t-shirt design contest last week and entries have been rolling in. Check out the updated contest post for logo images and the font. Here are couple of the entries we've received:

SMD soldering practice kit


Here's an interesting kit put together just to help you work on your SMD soldering skills. It's got 49 SMD LEDs on the front with a programming header and switch jumper. The back has an ATtiny26L and a coin cell. At only 3V, power management is essential; all of the example programs are only addressing one LED at a time (imperceptible to the human eye). If you turn on too many LEDs at the same time, the voltage drop could cause the AVR to reset. Included example programs are a scrolling marque, bouncing balls, and Conway's game of life. SparkFun has tutorials for regular SMD soldering and using a reflow skillet. The video below shows the kit builder attaching just one LED using the heat and slide method.

Improved jog wheel


Taking a cue from the jog wheel we posted last week, [42ndOddity] has built an improved version. The design is based around a solid state rotary encoder instead of an optical encoder. The rotary encoder is far easier to attach and position properly. The knob is milled from scrap aluminum-it was a copier foot. To make the motion smooth, it's sitting in a bearing from the same copier.

Rebooting the magic SysRq way


[Cory Wright] shares a tip on how to reboot a system with a failed hard drive remotely. The magic SysRq key is a linux kernel feature that lets you perform a number of interesting operations. If you're working on a remote system where the disk has failed, you won't have access to the reboot or shutdown commands. You can issue keystrokes to the magic SysRq device in /proc though, so you can send a hard reboot directly to the kernel with no disk access required.

The Wikipedia entry includes a handy tip on how to properly restart a otherwise frozen machine. It should save you from having to fsck the next time around.

Subway hacker speaks


Popular Mechanics has an interview with [Zach Anderson], one of the MIT hackers that was temporarily gagged by the MBTA. The interview is essentially a timeline of the events that led up to the Defcon talk cancellation. [Zach] pointed out a great article by The Tech that covers the vulnerabilities. The mag stripe cards can be easily cloned. The students we're also able to increase the value of the card by brute forcing the checksum. There are only 64 possible checksum values, so they made a card for each one. It's not graceful, but it works. The card values aren't encrypted and there isn't an auditing system to check what values should be on the card either. The RFID cards use Mifare classic, which we know is broken. It was NXP, Mifare's manufacturer, that tipped off the MBTA on the actual presentation.

Autonomous paintball sentry gun


[Alan] pointed out this great commercial paintball sentry gun. The gun has a low power motherboard running Ubuntu connected to a firewire camera. Two high torque motors control the pan and tilt of a Tippman 98 custom. The control box allows for easy setup. You can change the sensitivity, color tracking, and firing modes. It also has a remote kill switch. All around a nice looking machine, but at $3K we doubt many of you will be buying one. Beta test video embedded after the break.

Best Firefox 3 extensions


We generally try to limit the number of extensions we install for security, performance, and because we use a lot of different systems. That's not to say there aren't a lot of interesting addons out there and Mozilla has recently announced the winners of their Extend Firefox 3 Contest. Lifehacker has a full rundown of each of the winners. Nothing really stands out in our eyes (although we might try Last.fm's toolbar).

The three extensions we always end up installing are Firebug, Greasemonkey, and Flashblock. What are yours?
