BaseCam board with encoders

I have been testing BaseCam board with encoders since November, I like them a lot.

- They provide enormously power with the GB90 motors and the motors run totally cool.

- The speed is very good, it is very difficult to move the gimbal too fast.

- And the best thing on my opinion is that if the gimbal is disturbed for any reason at any position, it just returns to normal operation smoothly and swiftly.

A short test with the LeViteZer gimbal with encoders.

This will be further tested on The Helsinki International Boat Show mentioned below

Gimbal testing

A year ago I was testing one of the first LeViteZer handheld gimbal prototypes at Helsinki International Boat show. It was with AlexMos 8 bit board.

Taking a video inside the boat is challenging. There is not after all that much light and even a big boat has narrow corridors and doors.

This year it will be 3 maybe 4 gimbals to test, one with BaseCam 32 bit board with 2 IMUs, one with encoders and the newest one with Phobotic CP controller and maybe also a GoPro gimbal with BaseCam SimpleBGC 32-bit Tiny.

The gimbal controllers really improved a lot during 2014, lets see how they will perform on a true challenge.

The Helsinki International Boat show is between 6th January and 15 February. Stay tuned for some substantial gimbal testing.

Temperature calibrated IMU test flights

Testing the temperature calibrated IMUs. On the 40 minutes of test flights the horizon was ok for me over 95% of the time (estimate, but it was ok) . On some situations like at the start of the video, or flying fast sideways and yawing to flight direction etc. movements temporally disturbed the Horizon, but it was soon levelled.

On these flights ‘skip the gyro calibration at startup’ was used.

This test platform is for GoPro, it is with Avroto 2814 motors and Maytech 40A Slim ESC with BLHeli FW. The flight time with 4S 5000 mA battery was a bit more than 10 minutes and 3850 mA went in, so maybe some 12 minutes max flight time. It is a foldable design and really compact when folded.

The gimbal is between propellers and the yaw is pretty special construction and with an encoder that gives reference to the frame. i.e. the gimbal follows the frame. At the start of the video when starting the motors, the gimbal moves to right, that is because it follows also yaw stick. There is still some tuning to do, now there is some bounce back after long yaws.

The yaw potentiometer modification is explained
here and some more videos also.

Next aerial platform/gimbal project is similar platform for panasonic LX100 sized cameras with T-Motor U5 and 16" propellers.
