@ryan - don't think it's out yet.
Can't wait for this though!
What would be *a-mazing* is a complete camera OS so that it can be super fast.

Hi all,
I'm one of the Stanford guys involved in the project. The external gyro is something Nokia Research got made to test gyroscope-using apps. It communicates to the phone over bluetooth with timestamped 3-axis angular velocities. Unfortunately the bluetooth communication isn't hugely reliable, even at such a short distance >snipped<

but hope that changes someday...
We could use a hardwired version of this in geophysical exploration.
What brand is the gyro if anyone knows?

If bluetooth is so bad for realtime data, how come the main game consoles nowadays all use bluetooth for their controllers? Most video game styles involve quick reactions....

The Nintendo Wii and the Sony Playstation3 both use bluetooth, i wasn't aware the 360 used a radio instead.

for accurate measurements it's more of a problem since the lag can be rather large and is probably not constant either. workarounds include timestamping (as mentioned, however how accurate clock does the other end have and how do you sync it when coms delay is not constant?)

usually when people say radio, without specifying the type, it's somthing more like AM/FM, RC toys, walkietalkies and garage openers
