[Update] This is a new OPEN LOOP system that is not yet available. NOT CLOSED LOOP. Sorry, for the confusion.
New Motorized Pan & Tilt head from Servo City. I used these guys to pick up some parts for the DIY motorized Juicedlink Slider project (here), and at the time they didn't have quite the Pan & Tilt head available for the end of a Jib / Crane. After discussing with them what I was looking for, they mentioned they were working on a new 'Open Loop' system that would allow me to operate the camera through the joystick control.
So here it is. It's a new Pan & Tilt 'Open Loop' system with Joystick control. Construction is top notch, and I don't know of a cheaper system out there. The product is not yet available, but it will be in a few weeks at ServoCity.com (Click Here).
