Hey guys, I'm helping my fiancé with her solo art show and she needs to move a GOBO projected light across a wall at a very, very slow pace, so that it takes about 8 hours for it to travel across the wall. Now we'll be using a gobo projector that will be sitting on a pedestal, so I was thinking I could create a motorized lazy susan to rotate it, but I wasn't sure if I could use a normal servo motor at such slow speeds or if I'd need to use a stepper motor. Servo would be preferable so the movement is smooth, but if that's not possible we'll have to make do.
Apologies if this is a dumb question, I'm a programmer by trade but this is my first foray into the engineering side of things. Thanks!
