A link was posted on another thread for a servocity.com SPT-200 Pan/Tilt system using RC-type servos. $49. I though heck yeah. With the new GoPro Hero2 HD wifi remote/streaming coming out in Feb, you will be able to not just use your smart phone as a viewfinder, but remotely start/stop recording.
So, I ordered. I wanted to make sure that the pan/tilt would stay where it was last pointed when releasing the joystick. Servocity has a servo driver that allows positioning using two small POTS, but I wanted to try a joystick. invenscience.com has a $34 joystick controller with built in standard servo plugs, and better - the unit is powered by a barrel plug with a usb at the other end (I put USB ports in my panel).
You have to use servos with the POT wired outside the unit, or in "continuous" rotation. Also called open loop. Again, this way, when you release the joystick, the camera will stay where you have it pointed.
Here is a video I did at home after putting the kit together and just powering from my computer. Sorry, low light, and I was just holding the pan/tilt system.
It works great. The speed of movement is too fast really, and I think it will be hard to precisely position in flight, but we'll see if its a factor.
I have a fiberglass "clamshell" strut mount I made for a different reason, that I will modify to hold the unit. It will clamp anywhere along any of my wing struts. A servo wire extension will be run inside the strut to the cockpit.
One other benefit with the current Drift camera that some of you may appreciate who have Drifts - you can spin the camera around in pan to make sure the dang thing actually started recording (little red light) when you hit the remote! Mine sometimes does not go on.
Will report more when actually flight testing:
