Here’s a SAFE way to destroy vampires… use a catapult to toss bundles of stakes at them from a distance! This game includes a functional catapult (with a range of up to 10 feet), a dozen bundles of stakes and a vampire’s grave to use as a target. The grave includes a coffin, stone vault and gravel pit. Build your own medieval war machine and let the impaling begin!
Very good to see the crew made it back safe and sound.
Space Shuttle Atlantis descended to a smooth landing at Edwards Air Force Base, Calif., concluding a successful assembly mission to the International Space Station. With Commander Rick Sturckow and Pilot Lee Archambault at the controls, Atlantis landed at 3:49 p.m. EDT on Friday
Quite amazing. I hope he builds some more computer parts out of wood.
… a few months ago, I had an idea as to how the divide by two mechanisms from my first marble machine could be cascaded together to actually function as a sort of adder or counter. Once I had that idea, I knew I had to try it at some point, and recently, I finally got around to building my marble binary adding machine.
The space shuttle Atlantis may have to stay on orbit a while longer until the weather decides to clear up.
Uncooperative weather at Kennedy Space Center, Fla., forced flight controllers to pass on STS-117’s first landing attempt today. The crew and the Mission Control team have turned their attention to the next orbit, which has opportunities available in Florida and at Edwards Air Force Base, Calif.
This is a solid-state Tesla coil. The primary runs at its resonant frequency in the 41 KHz range, and is modulated from the control unit in order to generate the tones you hear. So just to explain a little further, yes, it is the actual high voltage sparks that are making the noise. Every cycle of the music is a burst of sparks at 41 KHz, triggered by digital circuitry at the end of a "long" piece of fiber optics.
I personally think that this should be standard fare in a marching band. Just think of it for a second, it’s perfect. Loud enough to be heard over the roar of the crowd, easy to play (keyboard interface?), and it includes it’s own light show! Sure, it might take twenty people to haul the batteries around behind it but that is a small price to pay for something as spectacular as this. And just think of it in a battle of the bands. Put one of these on the point of your formation and the competition will drop like flies. You might need to insulate the musicians that have to march near it but that would sort itself out I would think.
