Stereo Encoder / Multiplexer
Spotted this on DIYlive…“This stereo encoder is the perfect solution for those looking for a high quality stereo sound transmission at a low cost. This stereo encoder produces an excellent crystal clear stereo sound and very good channel separation that can match with many more expensive stereo encoders that are available on the market. It is all possible thanks to a 38KHz quartz crystal that controls the 19kHz pilot tone, so you will never have to calibrate or re-adjust the circuit.” [via] Link.
Shawn writes “Here’s how to modify Fisher-Price Pixelcam (Pixelvision) camera to output audio/video via RCA cables for direct hook-up to TV/VCR/DV camera, rather than have to use crappy tape-drive in camera with RF output. Good instructions. Only thing missing is a pict of where to connect power cables.” 
Alspix’s how to on making a matchbox pinhole camera “My first couple of 35mm pinhole cameras attempted to be panoramic, wide angle jobbies but this time I thought it would be nice to get back to the classic square format. Here’s my latest contraption which uses 35mm film to provide square images of 24 x 24mm. Using this size means that you can get up to 50 exposures on a standard roll of 36 exposure film.” [
Wired article about earning a living by selling the things you make, in the virtual word – “Jennifer Grinnell, Michigan furniture delivery dispatcher turned fashion designer in cyber space, never imagined that she could make a living in a video game. Grinnell’s shop, Mischief, is in Second Life, a virtual world whose users are responsible for creating all content. Grinnell’s digital clothing and “skins” allow users to change the appearance of their avatars — their online representations — beyond their wildest Barbie dress-up dreams.” 
Remember 
Andrew Carol’s LEGO contraption “Before the day of computers and pocket calculators all mathematics was done by hand. Great effort was expended to compose trigonometric and logarithmic tables for navigation, scientific investigation, and engineering purposes. In the mid-19th century, people began to design machines to automate this error prone process. Many machines of various designs were eventually built. The most famous of these machines is the Babbage Difference Engine. Because of engineering issues as well as political and personal conflict the Babbage Difference engines construction had to wait until 1991 when the Science Museum in London decided to build the Babbage Difference Engine No.2 for an exhibit on the history of computers. Babbage’s design could evaluate 7th order polynomials to 31 digits of accuracy. I set out to build a working Difference Engine using LEGO parts which could compute 2nd or 3rd order polynomials to 3 or 4 digits.” [
