Do you know where to get one and how much they cost? Not a clue but I think he bought it in Germany. I know he still tinkers with it a lot. This guy designs medical equipment and he was working on the camera gimbal the last I heard, changing from a stepper to a closed loop servo so it would pan smoother. I don't see the advantage of a servo motor over a stepper in this application. A servo moves smoother than a stepper since there are no "steps". I understand but the big advantage of a servo motor over a stepper is high torque and at higher speeds. This application doesn't require either. A geared, 200 pole stepper would be just as smooth, IMO, a lot cheaper, plus a stepper can also be closed loop. Just my opinion having used both for various purposes in remote actuators and motion devices over the years. If the camera is mounted in a helicopter, why would a servo be needed to pan the camera? Just turn the helicopter. You need it if you want to able to shoot obliques. At a certain point you may want to point at a particular spot and have the camera track it as you descend and fly around it. My neighbor (who is also a major computer geek) is big into the RC flying thing. He's the president of a New England group of RC enthusiasts and is constantly building new and better airplanes and helicopters. I was joking with him one day and told him if he had invested the money in flying lessons that he had in RC aircraft, he'd have his ticket by now. It looks like a fun hobby but I know absolutely nothing about it. The realtor with whom we have our house listed is planning on having a video tour of our property made once the snow cover is gone and the grass gets green. He's going to have them fly a video camera equipped helicopter from the road, up our driveway, over and around the barn, house, pool and horse paddocks. Should be interesting. Perhaps this is what he's talking about. http://www.youtube.com/watch?v=X6svIcef5lQ If you want to go on the cheap and have a few hours to spare, you can build your own. http://www.stratus-productions.com/frame-kits Scroll down for the instructions video. |

Yabut, the ongoing joke is if you fly RC, you get to walk *towards* the scene of the crash. :-) Instead of hopefully away. |
