Post DIY motorized dolly rig with MX2 and Orion Teletrack mount
Ok I´m finally going to let my project fly here on this awesome forum..

My last timelapse dolly was made from lego and it worked ok surprisingly, but it was very unreliable and fragile so I decided to build a proper one.

It´s an omega belt driven dolly controlled by the Dynamic Perception MX2 controller. It´s somewhat a mix from different ideas I got here on the forum, but I was maybe most influenced by Tom´s intermediate dolly and this one right here: http://forum.timescapes.org/phpBB3/viewtopic.php?f=31&t=1511&start=0

I have some troubles with my motor, its a little to powerful for the MX2 controller, it rates at 2.7 amp at full speed(its a windshield motor from a 96 hyundai accent haha) but I think (correct me if I´m wrong) the MX2 doesnt take more than 1 amp, I want the power though, to be able to put bigger video cameras on there and run it realtime for video.. I´ll probably fix this by installing a relay between the battery and the motor.. I guess for timelapse work the MX2 will handle it without relay though, or I hope so.. If someone knows the exact stats for the MX2, sharing would be appreciated!

I still have to connect the merlin to the MX2 for programmable 3-axis moves but for now I´ll run it manually via the original remote. And for the interval trigger, I need that cable as well for the MX2 to run it, it´s just a custom cable, 2.5mm jack on one end and 3-pin(5DMKII) on the other right?

Anyway here are a few shots of the rig...feedback would be more than welcome..

That's a great build. The track looks very solid. It's nice and wide for stability.
The trolley looks solid too. I assume you do metalworking for a living.
The cutting, wielding and general putting together would cost more than a new,
factory built dolly if you had to pay someone to make it. Was your reason for
building this yourself because shipping would be too high for a factory dolly?
The DP rail can be reinforced to support more weight if that was an issue.

Hey, thanks for your compliment but no I´m not a professional metalworker, I learned carpentry but I like welding and playing with aluminium alot more.. I was thinking about the DP dolly but I live in Iceland and shipping would probably cost an arm and a leg + all the fees Iceland puts extra on shipments.. I like building my filmmaking stuff myself anyway, I get more out of using it if its homemade but works equally hehe..

but regarding the MX2 controller, My motor is at full power 2.7 amp but I think I saw a tutorial from Milapse about the MX2 is for 1 amp, will I fry the controller with time if I plug it in without any extra components? I´m currently trying to install an extra more powerful transistor and hoping it will work...my electrical skills are not the best
