> >And yes, I do know that there are one- and three-axis > > Can you name some of these 3-axis please? Analog Devices has one that'll be available RSN; Freescale makes several. The only one I see on the Freescale site is the MMA7260Q; not in stock anywhere I can find. At any rate, the package is too large. Apparently, per Digikey, STMicro makes some, too. I see at least three right off labeled as "TRPL AXIS". Check it out- I did a DK search on "accelerometer" and selected the link under "Sensors" in the results.
