I'm looking for comments/details/sources/suggestions concerning small
motors which could be used to step back and forth as well as run free
in either direction.
The application I have in mind (currently in early gestation, and in
case anyone's interested) is 8/16/35 mm film editing, where the motors
would obviously provide the main film transport mechanism. There'd also
be sprockets, shutters, etc. as needed, but these could presumably be
passive.
An ideal solution (I think) would be a motor that could be driven with
logic (or other) pulses: 1 pulse == 1 step, pulse train == run at
speed proprtional to pulse frequency. Makes for nice, simple controller
and display circuits.
Please e-mail any and all comments. I'd love a _cheap_ source for
something like this. And if anyone knows where to look for new or used
film parts (like those mentioned above) let me know about that also.
Followups to misc.wanted.
