The Paper Microscope
This site has a bit of information about a paper microscope kit, they’re only sold in Germany, but it looks easy enough to recreate these and make your own…“Here’s a microscope, made from nothing but paper, two lenses, a plastic mirror and a drinking straw. Although this is not the kind of material you would expect to be used in an optical instrument, the facts are quite amazing: 50 x magnification, gear drive for focus setting, high quality plastic lenses, mirror to collect light for transmission view.” Thanks Joevennix!

Excellent guide on procuring LEDs from a cheap and plentiful source – “They come disguised as “Christmas Lights” – the “Forever Bright” line is especially good. And they are the subject of this article. Why bother? Cost. A string of 75 BLUE LED lights costs $10 on sale – and up where I am there’s a $5 rebate per string for “Energy Saver” lights. So that’s five bucks for 75 LEDs – or about 7 cents per LED for the expensive BLUE ones. Cheap.”

Blue_Guy sent in this great collection of buses and trucks modded to RV’s. “Don’t look for any slick chrome-and-plastic Silver-Eagle RV’s converted by professional shops or retired backyard do-it-myselfers. All of the vehicles featured herein are original, one-of-a-kind creations which reflect the owner/builder’s lifestyle and architectural beliefs. True, some are little more than shanties on wheels, while others are an abrupt attempt to be liberated from stationary habitations, but at the upper end of the scale, you’ll find many which could be classified as genuine art.” 
Here’s how to make your own scratch off cards, fun for projects for kids and possibly an idea for starting your own lottery “For this 1 Minute Finger Tip you’ll need a piece of card, a green wax crayon, some green poster paint, a paintbrush and a black felt tip pen. And a spare minute, of course!”

The ODEO podcast studio is now open – I was on the beta, and it’s really fun – “…everyone can now record audio with the browser-based Odeo Studio – or via the phone. Either way, your voice gets posted as an MP3 on an Odeo page, and from there you can easily share it or edit the title, etc. We’ve also made some changes to how the site looks and works, which we think make it simpler and move it closer to our vision of Podcasting for Regular People.”
