Here’s a really cool PC Case mod, a DIY on how to make mirror-finish PC Case surface.

Spray paint your PC case and give it a mirror finish.
You won’t need expensive painting equipment and supplies.
You’ll find most of the products I used at hardware and
automotive stores.

3M Perfect It III Compounds and 3M Imperial Hand Glaze is usually sold in Autobody Supply Stores, but I’ve linked them to an online resource.
I prefer using carnauba type car wax, but any automotive wax will work fine.
Regardless of wax used, you must allow paint to cure for at least 30 days before applying wax.

Here’s a great demonstration of a levitating magnet with 2 high-speed rotating cylinders.

Maybe someone can take this idea further and make us some hoverboards please!

While working on science museum exhibits in 1990 I came up with the above idea: it is known that a spinning metal disk will lift and fling a strong magnet. Therefore, metal rods with opposite spin will lift a magnet but WON’T fling it sideways. It works! I used “sched-80″ heavy wall copper tubes about 1-3/8″ diameter, 12″ long, with 1/4″ wall thickness. I hammered aluminum plugs into the tubes, carved shaft-tips with a lathe, built endblocks and bearings, spun them with an AC/DC motor, and managed to levitate a stack of two 3/4″ diameter neodymium magnets. The spinning tubes must move at about 5000 RPM before the magnet starts floating.

If you are thinking about making your own Parabolic Mirror, (whether you are making a parabolic solar cooker or simply just ‘caz) here’s great set of videos you can refer to for some tips.

You can make a parabolic mirror from an old satellite TV dish, or a bathroom vanity mirror but that’s not fun. Making your own mirror allows you to get the exact curvature you need for whatever you might be burning, cooking or heating. It’s a fair amount of work, but the resulting energy the mirror produces is amazing.

Here’s a really cool interactive multi-touch LED floor.  I wonder if they can turn this into an interactive game sorta like Nintendo Wii.

Sensacell’s latest contraption still manages to stand out by bringing back memories of when mouse trails really were the coolest thing about an operating system. Flashbacks aside, the installation — which is currently at the entrance to the Comunitat Valenciana in Spain — possesses over 1,000 interactive modules, each of which include capacitive sensors and a LED lighting system. The integrated tech enables it to recognize when someone is walking over it and consequently light up as if to leave an eye-catching LED trail of their path.

Of course, you probably won’t need this $500 mosquito catcher unless you are in super mosquito-rich area.

The first choice of thousands of US households as the ultimate weapon against mosquitoes. Mega-Catch™ Ultra Mosquito Traps have been further refined for 2007 and provide exceptional and trouble free mosquito control for all situations.
