Ah, the latest in projector technology is here and with a decidedly clever twist:
Japan’s electronics giant Sanyo unveils a new ultra-short focus projector "LP-XL50" in Tokyo. The LP-XL50 can project an image to fit an 80-inch screen from a distance of only eight centimeters (3.2 inches) from a range of positions and surfaces due to its new optical engine technology.
The resolution will be 1024 x 768 and is aimed at computer use rather than home theater use. I’m sure this will last about thirty seconds after the devices are released in the states come December. Sanyo unveils ultra-short focus projector
The countdown for the launch of Shuttle mission STS-117 has resumed at T-9 minutes after a scheduled hold. For more information quickly go over to the NASA Human Spaceflight web page and follow along.
It looks as if the dream of a solid state laptop is almost here. SanDisk, makers of mighty fine memory products (I use them in my digital camera) have introduced a 64GB solid state flash drive in a 2.5 inch SATA version for portable computers and knowing that the public’s hunger for music players will never be slaked, a 1.8 PATA version for things like, gee, I don’t know, iPods? It’s a short leap to the iPhone from here. 64GB of storage would be just fine for most people on a laptop. Even if it wasn’t the .11 millisecond reaction time and less than a watt power dissipation will make using these an easy move.
A number of years ago I video taped an amazing demonstration of iron filing manipulation choreographed to pop music at a local science museum. I was fascinated by the undulating tree like figures and the dry liquid waves that played across the surface of the tank. I posted the clips I had of the display on to YouTube so others could share in my wonderment. Turns out that this is not a one off display but the work of an artist named David Durlach. One of the comments on the clip pointed to an article on this amazing artist. I had thought the devices were an analog spectrum display but the happens that they are under elaborate computer control. This is an excerpt from the article on Discovermagazine:
This five-minute display is the result of hundreds of hours of programming, not to mention the computer language Durlach had to create to specify the details of choreography. In this language, Durlach not only shifts dust through the three spatial dimensions, he also plays with time, changing the rate at which it appears to flow, moving it forward and backward, to achieve especially fluid motion. One of the interesting things is that you can make time go forward and backward like a sine wave, he says. It’s as if you took the reels of a movie, and instead of rotating them continuously forward you moved them back and forth, woonk-woonk, woonk-woonk. That’s a very cool effect. Durlach goes on to enumerate the different ways you can play with time, and the effects they generate.
This is a fascinating look at just what would happen if you, theoreticly mind you, drilled a hole right through the Earth and jumped in. Can you say see you on the other side of the planet in about an hour? Oh yeah, there’s the issue of actually drilling the hold, evacuating the massive amount of air that would be in the tunnel and all those other niggly technical bits but just thinking of the concept is flat out fun.
Another useful tool for getting all creative with your LEGOS. A handy tutorial showing you common ratios for the gears that are common to the LEGO Mindstorm kit. You can also find these gears in a variety of other LEGO sets. And if your totally flummoxed about what gears are just having a look around should answer some of your questions.
