Chris at The Keeser has constructed a simple circuit to detect infrared light. You can make the project using only 7 parts. A schematic and analysis of operation is also provided. Parts Needed: * 1K ohm * 330 Ohm * LED * IR transistor * 2N3904 NPN transistor (any NPN will do) * Battery Snap * Perf Board “Test the circuit by holding it close to an IR remote control
The National Robotics Engineering Center (NREC) is coming up with some robot designs that are quite amazing! Dragon Runner is a rugged robot that is used for reconnaissance among other uses. Have a look at the video, it is quite impressive. “The four-wheeled device is small and light enough to be carried in a soldier’s backpack and rugged enough to be tossed over fences and up or down stairwells.

Not sure if there are any camera tricks here, if there isn’t this is an amaizing chair. Don’t mistake it for the common walking chair. “Raffaello D’Andrea’s latest dynamic art project, a chair that falls apart then puts itself back together! From the same artist who brought you the robotic table.” read more | digg story
Took a double take when I stumbled on this product! “Tired of waking up and having to wait for your morning coffee to brew? Are you one of those groggy early morning types that just needs that extra kick? Know any programmers who don’t regularly bathe and need some special motivation? Introducing Caffeinated Soap, the caffeinated soap from Xoxide… Engraved with a glorious “C” for Caffeine, scented with peppermint oil
Want to rock out with Guitar Hero free of the confinement of wires? Check out the wireless mod that Jeff came up with.

You can jam on the buttons or work the whammy bar and what you do is instantaneously reflected on screen.
John Solid has captured some fantastic tesla coil discharge pictures using his solid state tesla coil . There are pictures and descriptions of the entire project. “The Magnifier Coil has a resonant frequency of 150.3 KHz. It is wound on a 5.625 outside diameter PVC pipe. The winding length is 21.9 inches made of 24 guage enamel insulated magnet wire. The capacitive load for the coil is a toroid constructed
