Post Home made time-lapse rig
I've just finished my first time-lapse slider with a budget about 50$:

Very nice dolly! Some very original ideas in there. I was amazed to see that little motor pull the trolley uphill. The leadscrew design gives it a tremendous mechanical advantage. Does the potentiometer control the motor through a PWM, or just by reducing current to the motor? You will get better low speed control with a pulse width modulation type speed control. They are very inexpensive on ebay and elsewhere. What are the extrusions at the edges of your track from? They look like a more generic part than Igus or 80/20 specialty extrusions which can cost kind of a lot. Some nice timelapse done with it as well.

At the moment I am just reducing current to the motor and I know that it is not the best solution. I'm goint to replace it with more advanced integrated circuit.

The extrusions at the edges are... from sliding door system, which cost me about 15$:
