Kids really chew into your spare time. I got some time the other day to have some fun with a Raspberry pi, raspicam, Adafruit pwm servo driver, 2 servos, double sided tape, tape and cardboard. In 60 minutes I managed to make the “thing” in the video. OK, some stuff was pre-assembled :-).

Also, I’ve just finished setting the construction up running on Battery power. 2x zippy compact 3300mah 4s (14,4v nominal LiPo) in parallel via a 5v 5A bec powering both the servos and the Raspberry hardware. Running everything including servos for 4 hours , my measurement is that I’ve used less than 10% of the battery capacity.

The servos are currently controlled using up, down, left and right keys and the application is just a modified example from Adafruit. However, it should be very easy to integrate with either the mpu 9150 breakout unit I’ve also installed and make a simple gimbal of sorts.

But first I’m planning to test integrating the code with the opencv haar object recognition stuff I did during the Christmas holidays, for example track clementines.
