Just going through my plans to build a camera slider.
To keep weight, bulk and price down, I want to use the smallest stepper motors that still adequately do the job.
I'm considering using counter weights for the slider part of it. I suppose I could just muck with weights after I've built it but I'm curious about the maths.
I found this site and dunno if it's the right formula or not but I don't really understand it anyway.
Also, I don't want friction to be a part of this calc, and just for kicks let's say the camera weighs 1kg. Oh and I know you're gonna say "but adding a counter weight IS adding weights" but we'll ignore that for now. I have other design ideas too, and I'm only mostly concerned with the camera's weight at different slider angles.
So, consider the slider is level. I don't need any counter weight the keep the camera balanced with the motor.
If the slider is at 90deg, the counter weight should be the same as the camera.
Ok so what if the slider is at 45deg. Is it as simple as the counter weight being half that of the camera ? I doubt it.
Then what if the slider is at say 30deg or 60deg ?
