OK I see it now.
This is technically a motorized camera slider.
Yes it might work for short exposure like 1-2min or more. I don't know.
But this is not a stable work.
System looks very simple but keeping camera stable will be very difficult.
Also I want as soon as possible small thing that going to my bag and easy to set for shooting.
This video show how easy to use of this YSF rotator
I want that easy even more easy ;D
I'm doing it.
I'll do some hardware modification today.
Actually I'm all done I just have a problem with size and combine that 2 codes.
That's way I'll cut the motor shaft and also probably will do a custom gearbox for smaller size.
