Watch the video above to get an appreciation of what the double pendulum is capable of when it is free wheeling. Have a look at the furuta pendulum project that Oyvindbjo made at Norwegian University of Science and Technology. I have added some of the calculations from Wikipedia for some amusement (I have no idea how to decipher it). "For swing-up it uses feedback linearization and a controller that
Embedded video from CNN Video Oliver Yeh, Justin Lee, Eric Newton have put a camera into near space and took a ton of pictures for a cost of only $150. The most interesting thing is that unlike most of these balloon projects there was no custom electronics involved. Instead they used a GPS enabled cell phone to send them the GPS location data. "We designed a low cost balloon-launch
This is a cool work of art by Tod Kurt called the Crystal Monster. It shows off the power of 18 BLINKM MAXM that are neatly placed in the custom laser cut box. You probably remember some of the cool Roomba Hacking that Tod also does. "It’s made from over 400 sheets of laser-cut acrylic, more that 240 feet of LED tape (>2200 RGB LEDs!), and around 500 steel

Syncin’ n’ Sprinkin’ from Pete Lewis on Vimeo. Pete Lewis from Spark Fun have built a cool Smart Lawn Sprinkler project that is designed to save water by only putting it where it can be used. It does this by varying the water pressure to restrict the distance that the sprinkler can spray. It is a crude method but works very well! A potentiometer is used to measure the

If you are tired of the ordinary why not stuff all of your favorite consoles in something that look cool like a R2D2? That is exactly what Brian De Vitis did! Via: Popular Science via Hack N Mod
The guys over at Mana Potions have developed a cool new way to play the new AION and get some exercise at the same time. Looks like running and flapping at the same time may be kind of hard but it is a good idea to get a bit of a workout. I wonder how long it will be before more game consoles and game manufactures make exercise part of
