@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.

Bluetooth has been hopelessly useless for real-time data for years,
but hope that changes someday...:rolleyes:

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 xbox360 uses radio, not sure about the ps3 though

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

bluetooth is "good enough" for video games since there are other lag sources as well and one doesn't need anything approaching true realtime performance for gaming anyway (all games that run on windows are proof enough: platform general lag is some tens of ms just about always). consoles probably run something that looks much more like realtime.

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?)

eee isnt bluetooth radio ?

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