I am very new to the world of DIY motion control. I am reading a lot everyday to make up for my lack of training and knowledge in this field (I am a Chemical Engineer/Materials Scientist) and its been a very exciting few days.
My question relates to macro photography and a custom setup I am trying to build for that. I have a lot of macro gear including a Nikon PB-4 bellows unit, and lenses that can take me all the way from 1:2 to 5:1, leading to obvious depth of field problems, for which I am considering stacking my shots. I shoot with a Nikon D200 btw..
This is something that I can do it by hand, but I thought it would be more fun if I can build my own little setup.
One of the goals is to control the PB-4 with a stepper motor using Arduino. My initial thought is to couple the stepper motor with the bellows movement knobs on the sides and use that to rotate and control the linear motion of the bellows.
I was looking for recommendations for motors I can use, because I have no idea what the torque requirements would be. I don't except to use heavy lenses with the bellows.
Also....can the Arduino board power the motor, or do I need to get a separate power supply? I intend to use the setup in the field, so the Arduino itself would be battery powered.
I would appreciate any information. I apologize before hand, if the questions are very elementary, but I am somewhat of a noob in this field.
Thanks and regards.
