Greg Fletcher replied to Miguel Sepulveda's discussion Legacy source code for Ardupilot w/Atmega328
"First I must ask, why bother with one of those. Do you have thermopile sensors or a imu sensor board. I flew one of these a back in those days. Had 3 axis thermopile and GPS and 2 way telemetry. I may still have a copy of the firmware that I…"

Greg Fletcher replied to Robert Wells's discussion Quad Copter Log Analysis Post Crash
"I am not sure what the cut off point for running on APM. Old hardware is fine and 3.2 I think is the last or close to the last version. You have to find your real problem. Look for loose connections and also for little whiskers or stray wire stands…"

Greg Fletcher replied to Robert Wells's discussion Quad Copter Log Analysis Post Crash
"Your log contains almost no information. The only thing being logged is attitude and RCin. Not much to go on. I don't even see a crash at the end. You RCin just end with the sticks not centered, so that tells me that the log just ended mid…"

Greg Fletcher replied to isfandyar01's discussion should throttle be closed at ground of plane in rtl and auto mode is it normal?
"If the throttle/engine works in manual mode it will work in auto. Have you set up your ICE_ parameters yet. That may be it. The behavior I described is for an electric plane. With an ic engine you would start it in manual unless you have an electric…"

Greg Fletcher replied to isfandyar01's discussion should throttle be closed at ground of plane in rtl and auto mode is it normal?
"That is normal behavior. I manual and fbwa the throttle is directly controlled by the pilot. In all other modes the pixhawk controls the throttle and it knows it is not flying so it doesn't run the motor, with the exception of an auto takeoff…"

Greg Fletcher replied to Augusto Lombardi's discussion my First question
"I like the Storm32 controller. You can get one for ~70 - 80 USD from China, that's with a gopro sized gimbal! I haven't really used other types. There's lots of  gimbals that size for ~ $200, if you want motor encoders you will…"

Hi there Greg,

Yes, I'm still working on the camera stuff, but not as mutch as I would like.

The most recent version of the code is in the APM_Camera git branch.

It contains libraries to control the mount (AP_mount) and the camera (AP_Camera)

There is also some documentation on the wiki.

It would be nice to join efforts.

Hey  Greg ! It hit me while I was sleeping tonight and woke me up ! Getting baby scale is an Excellent idea! not just to weigh the plane but if I get one that shows ounces and fraction of ounces I can weigh each item and figure it's moment before I put it in the plane and help figure the best spot for it from the COG + or - and keep the trimming ballast to a minimum. the rest of the plane will be foam  I have been looking at power plants and might do Something Novel ? I am aiming for  a take off weight of 4 1/2 to 5 pounds  if I get a power plant out of something 7 to 10 pounds it should be lots  Thanks! Have a Great Day!

Hi Greg,

I read your posts that you have made a camera gimbal stabilizer. I work on Arduplane source code, with the APM-1 board, attaching 2 servo to work out solution for 2-axis stabilizer. It will be helpful if you could share your source so that I can have a look at it to get a better idea !
