On the subject of the frequency of light: I wonder if they've thought about using a green laser. My understanding is that our eyes are like 5x more sensitive to greenish frequencyies than red or blue. I've got a few laser pointers, all in the 5mw power output range, but the green ones appear much brighter than the red ones. Seems like they could use a green laser that put out less power ( and thereby less likely to cause damage to the retina ) but it would still appear just as bright as a red laser of higher power.
I don't know if the fact that our eye's are more sensitive to green means that they are more easily damaged by that frequency of light.
And the transcript of it singing would go something like:
HAL: If you'd like to hear it, I can sing it for you. Dave Bowman: Yes...I'd like to hear it HAL....Sing it for me. HAL: It's called "Daisy" Daisy....Daisy.....Give me your answer due.....I'm half-crazy....all for the love of you....

not only did they design a version of pong that is painfull, but their web site is unbearable. I've got that horrible green background color burned into my eyes.
One could make the point that stars wouldn't have to collide to destroy Earth. Simply another star passing close enough to affect the orbits of the planets could take out most life on earth.

Mini-PC w/o Fans?
·
· Score: 2, Informative
As Tom's says, the 3 supplied fans are quite loud.
I went to Radio Shaft and picked up a couple centrifugal fans which are almost silent but move a lot of air. And once I decided voiding the warrenty was an option, I replaced the powersupply fan and the rear exhaust fan. A resister on the CPU fan helped quite that one. Finally with rubber insulation between all the body panels and the fan mounts, and a nice coat of black paint to match the TV and reciever it works pretty nicely.br>
With these mods the sound is hardly noticable above the already existing sounds in the apartment like the 'fridge and A/C.
One problem I would still like to solve is figuring out how to push the FSB down to 100MHz when using a stock 1GHz PIII. This would let me slow the CPU fan down even more than it is currently.
The Microdrive's disk does have less mass than a CD, but thats not a good comparison since the two storage mediums are read differently.
I my experience, (I used to work in a photography store) IBM's microdrives have much lower tolerance than a standard desktop or laptop harddrive. Of the 6 microdrives we sold while I worked there 3 of them broke.
Reliability issues aside, a hard drive the size of a compact flash card really is a pretty amazing little piece of technology.
Oh you could try filming from outside someone's window....
It's just that whole "sounds like a flying lawn mower is outside my window" bit that might let people know you're there.
Ailerons is easier to say than "Left or Right Cyclic"
And in the case of R/C stuff, a lot of equipment is used in planes and helis, so it makes sense to use the same terminology.
What radio system are you using?
I've been flying for about 6 months now, and I would hardly say that doing a loop and a roll are as easy as "flicking a switch".
Just simple hovering really requires constant attention and corrections to stay in the air.
You have to remember that while this structure would be incredibly long, it wouldn't necessarly be that massive.
Look at the world trade centers for example, in human terms those were unbelievably massive objects, and when they crashed they didn't exacly cause an earthquake.
So while a space elevator crashing to earth might cause a lot of damage where it falls, it's not going to trigger any large scale disasters
Are you familier with geosync orbit? The space shuttle is in low earth orbit and thus has to complete an orbit in approx. 90mins in order to "fall" around the earth. But if you get up to about 36,000k (I think thats right) your orbital time would be exactly 1 day. In other words you would be in free fall around the earth, but the ground below you would be rotating with you.
Look at the moon for example, it is so high that it takes ~30 earth days to orbit.
yeah, it's a matter of security.
And when I asked UUNet to let me create limited SQL account on our server that we're paying $3000 a month for them to host, the level 1 tech that I talked to said it was a security concern. Then I talked to the next level tech above him, who agreed our method was the most secure but he couldn't do it because it might confuse the support people. Then we talked to our account manager who finally admitted it was not a security concern at all, it was in fact a marketing concern.
Try some thin CA, that particular evil substance has held the rubber pads on my Inspiron 2100 for almosta year now. Along with anything else that breaks in my house or on my RC toys.
why would we go all the way to pluto for water? its a hell of a lot closer to just goto Jupiter and get some of the water off Europa.
Its a hell of a lot closer to go in my backyard for water. And it'll save billions of dollars!

If you really want to see a good example of how much energy you can store that way, search the web for videos of RC helicopters when they loose a blade in flight. I've seen a couple just disappear in a cloud of debris in midair in under a second when they lose it.

but they nowhere near the Japs.
Perhaps in terms of being not being in pretty packaging or commercialized. But they are just as, if not more, intelligent than the japanese robots.

The next thing you know they'll be researching a way to attach these frickin' lasers to shark's heads.

They didn't provide a link, but they did provide a name, and you have Google to thank for the rest.
