Then I would ask a favor. I've seen photos of numerous guides and forums, but I would like to ask you a definitive guide, with a list of materials and electronic items for the construction of a motorized dolly.

I think with my friend to do a documentary with timelapse scenes in slow-emotion (We started a few weeks to run) of the Sibillini National Park which is located in central Italy.
The project is very ambitious and will cost us time and effort, but would like to do something truly unique in Italy has never been realized.
Soon we will open a blog and a Facebook page, meanwhile, to get an idea of who they are you can find me at my website and on Facebook.

Many thanks for any reply.

Depends on your budget and how much control you want.
If you want to save yourself a lot of headaches, just buy a dynamic perception rig.
Failing that you could build something from anywhere from about $200 upwards.

What are your requirements, and what is your budget, and are you good at building things?

My goal is to create a Time Lapse both static and moving (during both night), along with the video in slow-emotion model of Timescape.
My budget is max 500 € for the moment.
Keep in mind that we should move with my friend and walk a lot, though I think other people will join this project, because we need both economically and to carry the tripod dolly and two and all the photographic equipment.

"Fraa" its very detailed guide of the construction of his dolly:

They are well accepted other offers. You do realize that to make this documentary, I will work in quite extreme weather conditions (low temperature of -10 / -15 degrees, wind etc.)

Thank you very.

Ive seen Fraa's dolly, it looks very well built, very nice system indeed.

you can also check out Project Chronos, there is a thread for it on here linked in my signature, it is also on openmoco.org and at sourceforge.net, just search project chronos. it is another DIY timelapse rail i developed, i have put a lot of info including the code, schematics, parts list, etc at sourceforge.net. I have used it in 15 degree weather with no problems, it is very portable and simple to use with very smooth movement.

you can also look at a system from dynamic perception if you want to double that budget, while it costs more than a DIY system it is a proven system with loads of support and used by many.

In the end I think I realize it through the guide very detailed Fraai, modifying it slightly, especially the parts exposed to the elements.
And if I want to mount a motorized head, do you think is possible?
How would seize it cost?
