I'm a bit lost... sensors?
I know very little about camera technology.
What camera has a sensor, and what can the sensor sense?
Are you saying that I could buy a camera that could sense lines marked at 10degree intervals on a spinning lazy susan and I could program it to take a shot at that point?
No camera doesn't have sensor, you have to set them up, the camera just needs a remote control input of some sort.
There's all sorts of sensors, light, magnetic, and as Mark says mechanical switches being the most common for this sort of application.
For light you'd have a light source, (perhaps even a laser) focused into a beam, fixed to the susan, with photo detectors at the 10deg intervals. Just a simple circuit to couple all the photo detectors to the camera.
Similar thing with magnets.
Most cycle speedos use magnetic sensors, magnet fixed to a spoke, sensor on the forks, that counts wheel revolutions. you don't need the counting part just the sensor a lot more magnets, and an interface between sensor and camera.
A mechanical switch may be the easiest, you just need activating cams at your 10deg intervals and a simple micro switch, that's also more likely not to need an interface to the camera.
Don't bother going to Dick Smith but somewhere like Jcar may be able to help.
