Newb needs help!
Ok, guys - I'm stuck here.
I am a film maker and hobby-level electronics enthusiast. I have a project in which I need a way to pull focus (turn the focus ring on my panasonic dvx100a prosumer video camera) to 3 preset points via a remote.
I have been told that I can create something with STAMP, and that I could find the geniuses in this forum to help me work this thing out.
I'm a programmer by day, so the code isn't an issue - but the actual hardware situation is boggling my mind.
Anyone care to help?
Details:
- Must turn focus ring on camera to 3 different points
- must be triggered (each point seperatly) by remote control
- must have its own power (I've heard tell that a 9v will do)

Does the focus ring have a gear or gear-like circumference?

Another option would be to go with PID, rotational sensors, and motor feedback, but unless it's imperative that motors never mis-step, steppers are far easier for a hobbist.
As for the remote in, you didn't say RF, IR, or ultrasound... Still, I've seen code for everything from SONY universal remotes to keyfob type transmitters--even roll your own with hobbist knowledge. R/C Tx/Rx pair interface with PULSEIN. Request specifics as project develops.

There is also a wireless version out there somewhere.
