The V3 Motorized Dolly

The V3 aka Dolly Parton is together with my merlin telescope mount a 3-axis motorized timelapse dolly. It´s driven by a worm geared windshield motor from an old car and pulled back and forth using the “omega drive” method using abec 7 skatewheel bearings, a belt and the main pulley. The rig is operated from the MX2 dolly engine. It´s able to run continuously or with the SMS (shot-move-shot)method, so far only the dolly itself is controlled with the MX2 but it is able to run everything, including 2-axis motion from the merlin and trigger the intervals from the camera. I´ll fix me the camera cable soon but plugging the merlin to the MX2 remains for future projects, as of now it´s controlled with it´s original remote manually. I use a 12V 7ah heavy duty battery to power the system. It runs for a long time if the rig is used only for timelapse. The motor is powerful enough to do realtime moves for video as well, but for that I´ll need to install a few extra components..Which I will.

Update: I have the 2.5mm jack – 3-pin cable I needed for controlling the camera directly from the MX2 and I fixed motor amp issues by installing a power transistor to the system, Which means now I have a motor 3 times as powerful as the one recommended for thr MX2 but no risk of frying it.. Runs like a tank and can easily move the whole rig in an incline.
