Hack a Day
You can have a lot of fun tinkering with the Raspberry Pi. But in addition to the low-cost hobby potential it is actually a great choice for serious data harvesting. This air quality monitor is a great example of that. The standalone package can be taped, screwed, bolted, or bungeed at the target location with [...]

Hack a Day
Go to any concert, show, or basement band practice, and you’ll find someone recording a bootleg. While these live recordings are sometimes fairly high quality, bootlegs recorded with a cell phone usually sound terrible. The guys over at Open Music Labs have a great solution to these poor quality recordings that only needs a few dollars worth [...]

Hack a Day
Do you think it’s not really possible to get amazing resolution from extruder-based 3D printers? You’re wrong, and this post about the attainable quality of prints on the Ultimaker proves it. The Yoda bust seen above was printed with a layer thickness of 0.02mm. This is a hack in itself because this process actually used [...]

Hack a Day
It’s no secret that the audio quality of the iPhone’s built-in speakers isn’t exactly what you would consider to be hi-fi. Sound quality aside, there are plenty of times where even the volume doesn’t do the music justice. While you can always go out and buy a fancy dock to amplify your iGadget’s sound, artist [...]

Hack a Day
Looking to make a quality light box more portable, [Hharry] designed a collapsible version complete with adjustable side lighting. Light tents are used by photographers as a stage for photographing small items. The use of multiple light sources, and a fabric that will diffuse them, means a reduction in shadows that might otherwise ruin a [...]

Hack a Day
The next time you set off for a long day in the coal mines, forget the canary – bring your Roomba along instead! While we are pretty sure that canaries are no longer used in the mining industry, this Roomba hack could make a suitable replacement if they were. A team from the Public Laboratory [...]

Hack a Day
The polished quality of this hack isn’t quite there, but we love the ingenuity and exploration exhibited. [Paulie1982] shows us how to make an old cellphone work with the rays of the sun. You can see above that he’s added photovoltaic solar cells to the back case of what looks like an old smart phone. [...]

Wirevolution
I will be moderating a session at ITExpo West on Tuesday 5th October at 9:30 am: “Building Better HD Video Conferencing & Collaboration Systems,” will be held in room 306A.
Here’s the session description:
Visual communications are becoming more and more commonplace. As networks improve to support video more effectively, the moment is right for broad market adoption of video conferencing and collaboration systems.
Delivering high quality video streams requires expertise in both networks and audio/video codec technology. Often, however, audio quality gets ignored, despite it being more important to efficient communication than the video component. Intelligibility is the key metric here, where wideband audio and voice quality enhancement algorithms can greatly improve the quality of experience.
This session will cover both audio and video aspects of today’s conferencing systems, and the various criteria that are used to evaluate them, including round-trip delay, lip-sync, smooth motion, bit-rate required, visual artifacts and network traversal – and of course pure audio quality. The emphasis will be on sharing best practices for building and deploying high-definition conferencing systems.
The panelists are:
- James Awad, Marketing Product Manager, Octasic
-
Amir Zmora, VP Products and Marketing, RADVISION
- Andy Singleton, Product Manager, MASERGY
These panelists cover the complete technology stack from chips (Octasic), to equipment (Radvison) to network services (Masergy), so please bring your questions about any technical aspect of video conferencing systems.

remote-exploit & backtrack
I have a X61s, and connected and disconnected the antenna at least 10 times, not more than 20-- and I currently get a weak wireless signal compared to other people (detail below). I am also running a X61s with some Lenovo software, so I'm not sure if the software is lowering the signal, but no matter what I do it still seems like I can't get it as high of a signal. Would removing the antenna connectors (cable at the 3945abg card) that many times damage it? I just bend the cable side up and the connector pops off.
As for low signal... I have a router running Tomato, and other computers in the same room get quality of ~60, and ~35-50 in the adjacent room (quality being dBi difference between noise floor and signal quality). However, my computer gets about 30-40 in room, and 10-20 in the adjacent room--and drops off much quicker a few rooms down.
If I want to fix it, what would I have to replace, or is there some other fix possible? (dip it in solder?)
