A time lapse dolly adds a very dynamic touch to a normally static form of photography. I have built several dollies over the last few years, my first used a BBQ rotisserie motor and what ever else I could find in my garage. The results were pretty good for being made out of garbage. I have built and learned and I think my latest system is the best yet. Using 123D and 3D printing I was able to create and print several custom parts to produce this dolly. I am trying to raise enough money HERE to sell these systems but I am more than happy to share my build plans and 3D files with everyone. I know not everyone has a 3D printer but there are many printing services online that you could use. I am planning on selling kits ranging from just the plastic parts printed or injection molded, if I can raise enough money, all the way to a complete system as well as combination in between including the electronics and motor.
This new dolly is lighter, stronger, cheaper, faster to set up, more compact, and better looking than my last one.
Here is a promo video I made.
Lets get on with the build!
