Here’s Captain Kimo’s home brewed DIY DSLR Camera Slider with a motor made for under $40usd. I used a telescope motor and some PVC pipes and wood that I found laying around the house. Everything was glued together with hot glue using a glue gun. The entire setup is very sturdy and works pretty good. The slider motor designed for telescopes moves very slow so this motor is only good for time lapse photography.
