I remember that fluid lenses have been used by holographers for a long time, because they can be of quite high quality even with large diameter. Vari*lite also uses fluid lenses in some of their intelligent lighting fixtures.
The News here is that the Philips lens can be focused by an electric field with no part moving other then the lens. The size of their prototype is tiny; IMHO they need at least to triple the size of it to make it useful for digital cameras.
I like to see holographic media advancing. Optical data storage really seems to be the technology of the future, and a commercial drive to read holographic media is a big step forward.
But what this drive does is only display the pre-recorded hologram, it cannot generate or modify the data stored in the hologram. It is much, much more diffucult to record such a hologram, in marketing wording:
4) Copying of the media is very difficult;
CDs have been successful in the past without being recordable, maybe this media, too?
The movie or record industry will surely like a type of media that only can be created by specialized (and licensed?) fabs.
And because of their size these are called 'Pizza Wafers'.
The die size of an Athlon XP is about 129mm^2, so at 3/4 surface usage about 410 Athlons would fit on a single wafer. Must be really cheap to produce those things...
USB 2.0 is not a renamed version of USB 1.1. Although 2.0 inherited nearly all features of USB 1.1, it added quite some features, most notably it added a high-speed transfer mode.
So USB 2.0 specification still supports the 'full speed' and 'low speed' transfer modes. Wise decision; did anyone expect a mouse running at 480Mbps?
Well, what is the 'USB 2.0' sticker good for then , if the device doesn't support the high-speed mode you may think. It simply says that the device is certified to work properly with other USB 2.0 equipment. I know about some popular silicon that is certified for USB 1.1, but will not work with a USB 2.0 host controller because of a design flaw.
So when you buy a USB 2.0 device and expect it to do real 480Mbps watch for the 'hi-speed' sticker. Otherwise it will only guarantee compatibility with other USB 2.0 devices.
LEDs are not very power efficient. Only the newest
types roughly reach the efficiency of halogen light bulbs. Fluorescent lighting is much more efficient.

... if you can have LaserMAME. Playing it building size is also no problem; much more fun then Blinkenlights :-).

Try www.btdesigner.com for bluetooth modules. :-(.
Exact documentation about how these things work still seems to be hard to find
Are you sure this is going to work ?
How do you tell the driver whih setor to read
when the write line is disabled ?
What about hdparm -r ?
isn't really a brand new idea.
The LCDproc ( site currently down) and lcd4linux and
some other projects have been around for quite some time now.
I have created an USB Interface for LCD modules that has some advantages over the usual serial or parallel port hack. I hope to release it soon.
mySAP has been running on ;-).
Linux for quite some time now.
But perhaps that's nothing for small businesses
