Re: [Gumstix-users] Who's Building a UAV?

[John G. <jg...@wi...>]

I'd be interested in the results of your IMU experiments.  I'm trying to do=
 my=20
UAV with an IMU, instead using thermopiles for horizon detection to maintai=
n=20
attitude stabiity.
If you're inclined, feel free to set up a wiki page on wiki.penguinpilot.or=
g=20
with your IMU test results.  Are you using gas/glow power, or electric for=
=20
the UAV power source?

  I'd probably feel better about using an IMU if I understood how to get=20
usable data out of them. =20

=46WIW, I fixed the link problem on www.penguinpilot.org.  It was a stupid =
html=20
trick that was preventing the links from working.  My forhead still hurts=20
from the palm-to-face moment I had.
