First test of my recently completed time lapse slider/dolly. I wanted to do this on a budget, so I bought some parts online and got the rest from parts from that big orange box store.
I am using the Dynamic Perception MX2 Dolly Engine, motor and battery (http://dynamicperception.com); a Manfrotto 468MGRC2 ball head; two Induro AKB2 tripod/head kits; Revolve Camera Dolly and rail clamps (http://www.revolvecamera.com).
Cog wheels and toothed belt are from McMaster-Carr (http://www.mcmaster.com), and aluminum plate from Online Metals (http://www.onlinemetals.com). Electrical conduit, Velcro, and various nuts, bolts and washers from the local hardware place.
