Hello,
I am attempting to construct my own motorized dolly for time lapse photography and need some advise/suggestions for the motor. Seeing as how ‘professional’ ones cost around $1000, I thought I would try my hand at building one before I laid down that kind of cash.
The design is simple, two tracks made of pvc pipe, a small dolly that is wheel mounted resting on the tracks and a motor at one end to slowly pull the dolly down the track. I need a one directional motor that has a decent amount of torque, enough to pull a dolly holding a DSLR camera on a small tripod, but is so slow it’s almost not moving. Realistically, I am looking at around 5 feet of distance over a 4 hour time span.
I thought about possibly using a DC motor, small pulley system and a speed regulator (such as this: hobbyengineering.com/H2246.html) to get the speed (or lack there of) that I need.
Does anyone have any thoughts or ideas? I would greatly appreciate it.
