Good evening!
I´m new here and i would like to introduce myself.My name is Christian, 33 years old and I live in Germany. I fly helicopter(Trex-450/Raptor E550) for almost two years and airplanes since one year.
The UAV stuff is very interesting. I ho

i have ardupilot mega and imu sheild "Oilpan"
so i'd like to see roll, pitch, and yaw on the serial monitor through ardupilot
but i don't know what to do.
I don't have a RC radio.
So i can't do setup(radio, modes) in serial monitor after uploading
Read more…This is a basic script for connecting U-Blox GPS to U-Center through an APM (as a middleman) basicly connects Serial 1 directly to Serial 0 (USB) bidirectionally, FYI you can modify the code to use the telemetry port Serial 3 as well.
This may be used

Attached are the reading from my gyros which seem to be very noisy, perhaps from vibrations.
Is this amount of noise seem normal to you? I think it's much to noisy and

I'm trying to get my XBees to work, using the Xtremebee board from DIYD on the aircraft side and the USB interface board that came with the XBee Dev kit.
So far, no dice! Has anyone used this board successfully? I have the recommended board on or

Thanks.

Without any knowledge of DCM, I'm porting a DCM implementation, that is used with SparkFuns 9DOF to C for ARM Cortex M3.
So far it goes well, but since I do not know what to expect of data in the matrices, I do not know if the current filter output d

I am considering a parachute on a 7Kg (15lb) UAV.
I have found various formulas on the web, but the question is what parameters to use.
What rate of descent should I choose so that, after a parachute landing, a well built but not overweight UAV will b

Just posting for some help. Now i'm in the design phase of my UAS and i'm looking into what sort of payload im goin to be carrying.
As for Cameras - I know there are a few on the internet designed specifically for what i require but as usu

my research team has recently bought a 1meter wide carbon fiber frame that can hold 24lbs. since the frame can hold that much we want to be able the carry that much. mulitple gps units, better INS, airborn Lidar, ...ect. So i was seeing if you guys h

Can anyone suggest why this was happening? Its random, sometimes after power on I got this, even after a few reboots, and then it goes away.
I armed the motors once when this was happening and it caused the quad to fli

This is my first post on the DiyDrones.
We are developing an autonomous quadrotor UAV, using Vectornav IMU and Mikrokopter ESCs with brushless motors.
The main MCU (STM32) runs three PID algorithms at 200Hz for roll, pitch and yaw axes. We

I have an Ardupilot mega & an IMU Shield.
After reading the manual on homepage, I connect these two.
But I don't know How can I see data such as roll, pitch, yaw and so on.
When I click Serial monitor after uploading, no data(roll, pitch...) ap
