Turn virtual 3D objects into real world objects
Here it is…3D-printing a SecondLife / WoW character, and mashup into Google Earth! “OGLE (i.e. OpenGLExtractor) is a software package by Eyebeam R&D that allows for the capture and re-use of 3D geometry data from 3D graphics applications running on Microsoft Windows. It works by observing the data flowing between 3D applications and the system’s OpenGL library, and recording that data in a standard 3D file format. In other words, a ‘screen grab’ or ‘view source’ operation for 3D data.” [via] Link.
Bcmeikle has a great way of making cheap(er) QuickTime video panoramic movies… “For some time now I’ve been making video panoramas but how to capture them has remained a mystery. Here’s a 
Great idea – check out Edward Vielmetti’s Superpatronbot – “Another evening’s work produced this working (but buggy!) Google Talk robot that looks things up in the Ann Arbor District Library catalog. Technology used: Jose Nazario’s from Ann Arbor’s DuckyLib library to do the RSS parsing of the AADL’s catalog, and Perry Lorier’s confbot (from Wakaito, New Zealand) to handle all of the Google Jabber stuff.” Thanks Brian! 
Fredrik writes – “There are lots of CPUs on the market that can be run at a lower voltage than what they are specified to. Especially the kind of low power consuming CPUs found in laptops. You’ll be surprised when you see the results of undervolting your CPU. In this article we will look further on how you can undervolt the CPU of a modern laptop without loosing performance or stability. Our test-system is an Acer Aspire 5021WLMi which appear to be a good computer to undervolt.” [
Here’s a homemade remote control pan and tilt system mounted on a competition class RC car. All controlled wirelessly, with the video piped into a head mounted display. We’ve all seen those minicameras mounted on RC cars but never like this. Awesome mod! 
Dissident75 shows how to set up a cheap xm radio in your house without buying the “home kit”. All done with cheaper/free parts. “This weekend I was bored and needed to do something. I had purchased a Roady2 XM Reciever for a exgirlfriend but broke up with her before giving it to her. Seemed like a shame to let it go to waste, and I had been curious about satellite radio for a while. Examining the package, it was a standard car install kit. Including the receiver, the antenna, 2 types of mounts (vent and pedestal), a tape adapter, dc power supply (cig lighter), and a few colored faceplate accents. Standard fare really. Useful for a car install but useless for a house install.” 
C Connors writes – “A student had a need for sound while running with his friends. Over several revisions, he has made several portable audio systems to provide entertainment at track meets and other running events.
