Have you done a range test with the LN96?
Sparkfun says it can do 1500 meters, but I don't know if that's just theoretical or actual performance.

Also, very nice servo control!

thanks,
1500 meters = .932 miles
line of sight is about .25 miles . figured i should be good.
i should be flight testing next week will let you know how it works

update
3-27-09
new board up and running

board

, 3 flight tests in so far , 2nd a 3rd test with acceleration compensation KML for goog

Success !!!! IMU / kalman / centripetal compensation working and stabilizing my EZG . from a 45 deg bank it snaps level in about 1/2 second.

another good flight today . both roll and pitch stabilized . time to start engaging my nav routine wich has been giving me great numbers . you can view flight in goog Mykml233402.A.kml
and view the log Mylog233402.A.csv

after further testing my home made PCB developed a connection problem on the pitch gyro so i had one made , ordered some solder paste ,found a small fridge and SMD'd the ICs from my beat up 5dof and lisy300 the SMD process worked great (used skillet as suggested on sparkfun ). and here is the result

AP

accept for the lisy300 every thing works as for the lisy i forgot to ground the PD and ST pins DOH !!
new board is on its way.

Good looking board! Neat trace routing and ground planes....you know what you're doing!

Why do you use the big through-hole resistors, and what's the thing in heat-shrink at the bottom?

Comment by wayne garris on August 14, 2009 at 9:51am

Thanks !
i used big resistors to make it easy to change them to adjust the OPamp that amplifies the absolute pressure signal therefor effectively giving it a much broader range and sensitivity . the heat sink is a dimension engineering 5.0v switching reg.
