    I took apart a bunch of ink jet printers to experiment with. This is my first attempt at doing PID motor control using an Arduino and the Adafruit motor controller.

      This video is more than you ever wanted about PID tuning for a multirotor. A brief overview of our control scheme is given, followed by a demonstration of tuning a quadcopter on a string and then in the air. Finally, for those interested, a set of simulations are presented to try and give an intuition about the terms. Also the consequence of having various parameters too high is demonstrated to help users identify tuning problems. Note: Axis lock is currently not in the packaged version of our software. Should be out shortly though.

        Did some PID tuning today, werry windy gusty day. Tried some slow, fast, high, low flying and i think the pid´s came out pretty good. Still have some oscillation when flying fast but the wind did some to i think.

          • PropAway beta for FPV : keeps the propeller away from the view

            PropAway for FPV will keep the propeller away from the view. A small microntroller in the plane will adapt the speed of the motor to make it match the video camera's frame rate. The algorithm will keep constant the speed AND the phase (angle) of the propeller, even in case of external influences such as wind. In this demo, I try to brake the propeller with my hand, and then with small sheets of paper : see how the command to the ESC is immediately adapted to resist the change. The visual indication of phase and command to the ESC as seen on this video is made only for debugging or visualization on a connected PC (developped in C# and emguCV) The microcontroller used is a PIC18F1320 using internal oscillator. The vertical synchro signal from the camera is extracted with a LM1881. In total, only 2 these two chips, 2 capacitors, 1 resistor and a hall sensor are needed. Still in development, for questions or comments please see full thread on http://www.rcgroups.com/forums/showthread.php?t=1305232 Thank you !

                Building on my small success with the rotary encoded motor I used the same set-up to control the print head positioning motor. I had to step up the voltage I was using to get enough torque, but once I got that figured out it works great.

                  Here are some more tests of the Gstabi H10. I've started really getting the hang of how to tweak it now I think.
