I'm trying to remotely turn on a Canon Powershot S5 camera. It has a power knob that you turn about 15 degrees and then it snaps back to center. Here's a picture:http://www.digitalcamerainfo.com/images/upload/Image/Canon%20S5%20IS/Product%20Photos/S5IS-top.jpg
Note that knob at the bottom right, with the "off" button inside of it. I'd like to simply turn that knob.
I was thinking a stepper motor glued to the top of the knob?
That's kind of a shot in the dark though, I have no experience with stepper motors. If I went that route, would I then use something like this to drive it?http://store.fungizmos.com/index.php?main_page=product_info&products_id=246&zenid=e9a645bf0b7067566c3ba2aa58502443
And any tips on which motor to use?
Or maybe I'm barking up the wrong tree?
Thanks for any help.
