3 axis gimbal solution


3 axis gimbal solution (2 min 37 sec)


The algorithm from yesterday worked as described. The yaw motor could move anywhere without a loss of control. It was the 1st time the yaw coupling problem was solved outside China. At least for a short time, no-one else in America could do it. The mane problems are now a very wobbly frame, lots of cables getting tangled, too much cogging in the DT700.

Both IMU's required heavy, shielded cable. There was once a page which said to only solder 1 end of a cable shield, to avoid ground loops. http://en.wikipedia.org/wiki/Shielded_cable

After fighting I2C glitches forever, remembering a Logitec webcam was connected to both ends of the shield, decided to solder both ends of the shield. That ended all the interference. So for an I2C device where the only return path is the signal cable, you need to ground both ends of the shield.
