First real product buyable with virtual money
Here comes an interesting trend – buying real world goods with virtual money – “The first real product, an XFX GeForce graphics card, is selling for L$20,000 or about US$80 (approx. $L250 = US$1). Makes sense, upgrade your system from work within the virtual world you’re running. What next?…How about something simple that generates from the SL itself, like user-created t-shirts a la something like Threadless? What do you think would work? Gosh, virtual currency for virtual things is going to be sooooo passe soon.” Link.
Monopole writes in about an open source 3D camera – “Stereoscopic Camera and Camcorder Synchronizer using the commonly available LANC camera control ports. Based on the Atmel ATMega8 microcontroller. Both the software and the hardware is open source, with board layouts on the website.” 
We’ve had a few emails and posts about folks who wanted to build their own lie detector, here’s one (and how it works) – “The circuit diagram of the Lie Detector is shown above. It consists of three transistors (TR1 to TR3), a capacitor (C1), two lights or LEDs (L1 & L2), five resistors (R1 to R5), and a variable resistor (VR1). Suitable transistors to use are BC547, BC548 or BC549, or any other small NPN transistor. The Lie Detector circuit works based on the fact that a person’s skin resistance changes when they sweat (sweating because they’re lying). Dry skin has a resistance of about 1 million ohms, whereas the resistance of moist skin is reduced by a factor of ten or more.” 
Wow, this stereoscopic motion picture camera uses two Mac mini’s as its brain – “The built in recorder of the 3DVX3 is comprised of two extensively modified Apple Mac Mini computers. The compact size and CPU horsepower offered by the Mac Mini coupled with the power of Mac OS X make the 3DVX3 a truly unique camcorder. Flash memory modules replace hard drives in the Mac Minis for fast booting and reduced operating temperature.” [
