So you think you want an accelerometer

i thought the wiimote did direction and rotation. according to this it does http://www.wiili.org/index.php/Motion_analysis

just thought i would bring that up

That page clearly says that the Wii remote contains only a 3-axis accelerometer, and does not directly measure rotational motion. It does explain how one may infer angular orientation to some extent based on the constant force of gravity, and maybe you misinterpreted that to mean it has actual rotation sensors.

ah....ok. thanks for the information

That link verifies Dave's earlier post. Unfortunately that post was made in 2006. SOOOOOO I resorted to Wikipedia... *sigh* I've been trying to cut back */sigh* anyways they verify Dave's post as well, and if people browse Wikipedia as much as I do, the page would be changed within seconds of any announcement or notice in change of the part.

If the Wii remote is anything like the original Xbox, there are several manufacturing plants and not all of them use the exact same parts. Look up "hacking the xbox" to see how S/N-dependant installing Linux on an Xbox really is. The serial number not only tells you the date, but also the place, mfg. assembly line #, etc, which also infers to which DVD reader you have, PIC16F encryptor algorithm, etc.
