I have a Thinkpad 560 which refuses to charge the battery. After buying a second battery and realizing that it was not a bad battery, I came to the conclusion that it was the L-shaped power management board inside.
At a computer show, I came aross a $20 trashed TP560, which I bought and used for extra parts - replacing the power board on my working 560. All went well for about a month - then that board blew as well!
So, I'm assuming that it may be the AC adapter or the motherboard that is frying the power circuitry on the 560's.
Aside from that, when opening up the chassis, I discovered that that IRDA transceiver was located to the left of the board (behind the power switch). The IR window, however, is located at the front of the unit no where near the transceiver. That is a pretty odd design flaw.
Here are some more astro pics taken through a telescope using a butchered Creative Lab Webcam3. It only has a CMOS chip (not as photosensitive as the Quickcam CCD) but seems to work ok.
Back in college, a ChemE friend of mine called me down to his dorm room to show me the sodium trick. His setup consisted of a ceramic bowl filled with water into which he dropped small pellet-sticks of sodium (removed from a separate oil filled jar).
The reaction was someone impressive but not nearly as some of the other explosives..err... "experiments" we had conducted before. So I offered my suggestion to pour some magnesium granules into the water and see what happens.. and so he did.
To our surprise, what followed involved more physics than chemistry...
He dropped in the sodium, which fizzed around for a few seconds, burst into bright flames.. igniting the magnesium granules.. which in turn vaporized the water.. ejecting 1000 DEGREE BALLS OF FIRE upward and in every direction. These meteors bounced off the walls, ceiling, and floor leaving holes + scorch marks in everything... the stereo, mattress, monitor, and his roomate's rare collectible $5 bill from 1891.
Luckily my body was protected by the door and my face with a plastic report cover.. heh heh heh.
I do remember something back in college about how transverse waves can travel faster than light.
Imagine if you had a really LARGE pair of scissors, and the velocity you're measuring is the point at which the two blades meet when the scissors open and close (note: the meeting point is not a physical object, just a reference point - but this point could represent an electronic signal just the same).
If one were to open and close these really large scissors very fast, none of the atoms would be travelling faster than the speed of light, but the point of reference could easily exceed that.
I thought Infocharms/CharmedIT, with their cyber-fashion shows, was basically a brilliant excuse for hot models to get close with technogeeks;) Hrm, I guess every company has to put out a product or two to keep the VC money flowing, and if that's what it takes to retain those models, so be it!
I'm looking forward to the bluetooth G-string and PDA bra (under-wireless of course)in the next show. Keep them coming!
I would imagine that with the right frequency and enough volume, one of these might be able to shatter window panes and other brittle objects. Can't wait to get one this Christmas!
Saw the movie last night. Read the book a while back. It's true the movie only skimmed the surface of what was in the book, but how much can you really pack into 2 hrs of film?
I must say the cinemetography for this flick was amazing.
Will definitely have to buy the DVD and check out the tons of footage that was unfortunately left on the cutting room floor.

That application would be much simpler than the glowing orb.
All you would need are 2 LED's that alternately blink yellow and orange.

The lunar pic is pretty.
There are plenty more astro photo's on the yahoo digital astro group:

Kids don't try this at home.

Checking out the specs in the pdf file,
it can be seen that this register comes
with a joystick/game port.
Sorry sir, please step up to the next
register, this one is closed

Very impressive, but do you run linux IN your swimming pool?
