Video Description
"Altium's NB3000 is such a cool little development board. This video demonstrates a little pan/tilt controller that I created using 2 mini servo motors. The NB3000 handles all the drive signals and I've created a custom script interface so I can control both pan and tilt at the same time. Let me know what you think."
