OmniDirectional Research Platform

[youtube=http://www.youtube.com/watch?v=-bcoAqKhdL4]

[Shachar Geiger] sent in an interesting project that he worked on with [Tal Avivi] at the Bezalel academy in Jerusalem. They were given the task of designing a 1-person electrical urban vehicle. They took some cues from MIT’s Transology and designed the OmniDirectional Research Platform (ODRi). There’s a video of it embedded above. It can be driven using three different input styles: an accelerometer joystick, a traditional gamepad, or body mass shift. They started with an Arduino, but needed more I/O and had to switch to a Wiring board (this was before the Mega). The platform is built mostly from scrap. The accelerometers were placed in an old Microsoft Sidwinder. The standard joystick is from a Sega Mega Drive. The weight sensors are out of cheap home scales.

NoiseAXE Minisynth

3172157928_b226c6b2e0_o

The NoiseAXE is a miniature synthesizer based on the Picaxe 08M microcontroller.  Its operating principle is fairly simple: a conductive stylus touches the leg of one of eight resistors to play one of eight notes, while a photoresistor controls the amount of modulation, creating a variable vibrato effect.  While the synthesizer’s output is rather limited (the NoiseAXE isn’t exactly a Yamaha DX7), it’s still a pretty cool little project; you could use its unique sounds to add that gritty analog touch to your next electro hit.  Check out the video clip below to see and hear it in action.

Reversing Google’s IPhone Voice Search

Google recently updated their Google Mobile App with a couple new features. Voice Search automatically starts listening when you raise the phone to your ear. Just say what you’re looking for, and it will poll Google and return the results. The app leverages Google’s voice recognition engine, which they’ve been training with Goog-411. [Andy Baio] has been experimenting with audio transcription and was curious what the new app was doing behind the scenes. He started by sniffing the packets as they traversed his network. Unfortunately, the size of the data packets transmitted is so small that he’s almost certain he’s missing something. He’d appreciate any help in this endeavor. Part of the problem might be Google getting special treatment and using undocumented iPhone SDK features.

Seattle Power Tool Race & Derby


Yesterday, the Hazard Factory, an industrial arts studio, hosted the 3rd annual Seattle Power Tool Race & Derby. Participants construct a dragster powered by at most two “power tools” to race head to head down a 60 foot plywood channel. The rules are fairly loose and creativity is encouraged just as much as performance. For an example build, [spacematters] posted his machine using a circular saw and inline skate wheels. A Flickr photo pool of the day’s shenanigans is coming together and you can see some of the registered entries on the Hazard Factory’s site.

ToorCon Seattle 2008: Lightning Talks


The second ToorCon Seattle got off to a quick start last Friday with a round of Lightning Talks at the Public Nerd Area. Each talk was limited to 5 minutes and covered a broad range of topics. Some talks were just supplying a chunk of information while others were a call to action for personal projects. Here are a few of the talks that we found interesting.

Defcon 15: WiCrawl From Midnight Research Labs


[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.

ToorCon Seattle Beta


I’m attending ToorCon Seattle Beta this weekend. Today was a single track made up of 20 minute talks. ToorCon is really best in breed when it comes to hacker conferences. Highlights follow:

Beetle, from the Shmoo, opened the conference with WiFight Club. Of course, by me mentioning that, you’re officially in WiFight Club. This will eventually become a competition that is summarized best with the phrase: “Faraday Cage Match”. He mentioned interesting projects like GNU Radio and others. I really want to see where this goes. It looks like a lot of fun.

Rodney Thayer’s talk on credit cards boiled down to this: everyone worries about internet security when doing online transactions, but that doesn’t really matter since the credit card company security policies are garbage.
