Submission + - Nanotube Loudspeakers (physicstoday.org)

ExRex writes: "An article in Physics Today alerts us to a simple loudspeaker design based on nanotubes.

Researchers from Tsinghua University and Beijing Normal University have demonstrated a simple loudspeaker design based on nanotubes: They showed that a thin film of nanotubes can reproduce sounds over a wide frequency range--including the full human audible range--with high sound pressure level, low total harmonic distortion, and no magnets.

There's a nice video of a nanotube speaker membrane being deformed without the audio being distorted. Here's a link to the full article at Nano Letters of the ACS."

Submission + - Help me Obi-Wan Kenobi... (hammacher.com)

ExRex writes: "Possibly the only way to watch Star Wars at home: The R2-D2 Home Theater System.

This is the only home theater system available that is modeled after the famous droid from the Star Wars films.
R2's head houses a DLP projection system with superior 1,500:1 contrast, and can project movies, TV shows, images, and video games from his radar eye at 1024 x 768 resolution onto walls up to 16 1/2' away, equivalent to an 80" screen....
There are lots of other features, including a remote built into a model of the Millennium Falcon.

Finally we can see Princess Leia's message properly projected."
