Lego from the Sixties and Seventies
NextBrick.net has a post about some really cool LEGO’s from the 60’s and 70’s from Mario, he writes “Dedicated to those of you LEGOmaniacs who are too young to remember the first years of Lego, or who have never had the opportunity to see some of these relics. During my childhood I spent tons of hours playing with Lego, and a large part of my small week’s pay buying spare parts. It would have been strange not to receive at least one Lego set at or birthday. My sister Elena and my brother Stefano are just one and two years younger than I am. They were very fond of Lego too and we usually played together to build very large cities. Not all of our Lego survived, but we still own a very large bunch of pieces, which I am pleased to share with you in this page.” Link.
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.” [
Harvey writes “Where US Taxpayer’s have already bought the best equipment (Like $2,000 hammers) and you can pick up it up for a faraction of its original cost. Get electronics and test equipment, pumps and motors, battaries and computer equipment by the pallet! Buy entire pallets of parts at a time and make the impractical dream a reality! NOTE: Read the fine print and watch out for shipping costs!” 
Makers, are you OK with paying more money for ringtone than you would for a complete song? These folks seem to think so – “According to The NPD Group, a leading provider of consumer and retail information, consumers are willing to pay more for a 30-second snippet of a song track to be used as a ringtone than to download an entire song track. In addition, consumers are willing to pay a premium (above the average $0.99 price for paid music downloads from the Web) for the convenience of downloading a full song directly to their mobile phone wherever and whenever they want.”
