The New Timelapse Slider - the Mechanics

As I have previously stated - the mechanics should be light and simple. I chose to build my timelapse slider around existing vieo sliders available on polish market. I picked a very simple, teflon-barings-based 80cm slider from Camrock.

I decided that the construction of the original product will be left untouched when my motorising set is attached finally. This is easy with Camrock, as it has predrilled holes on both ends.This made attachment of plates with axes easy. So I added:
- an aluminium box (or just square pipe profile) with attached 12V DC motor, 1.2Nm torque, 5.6 rot./min speed, like the one here

- a second end plate for the gearwheel
- a polyurethane belt, 6mm wide.
Motor wheel, opposit wheel and the belt are T2.5. The belt is open but attached to the bottom of the trolley with a Alu bracker, on which I cut crooves that fit the belt indents. The slider trolley is perfect in it size for my application; the recess below it perfectly fits the blt width and the whole layout (21mm x 11mm).

What I am still missing in the mechanical part is to round the end plate to have smooth corners.
The finished setup is really lightweight:

Completely redesigned timelapse slider is on the way

My previous timelapse motorised slider was sold some months ago. It was strong and sturdy, but not very portable and had some other limitations like that could not travel for more than 2hrs, could not move in a manner "shoot-move-shoot" and some minor others.
So I have addressed now all these issues. The preconditions are:
1. Portability
2. Shoot-move-shoot capabilities
3. Simplicity - the driver and power source in one package
4. Easy access to power source - just AA batteries for all (driver and motor)
5. Low power consumption - usage of DC motor

And here it is!
Prototyped electronics:

and finished mechanics:

As you can see the driver is based on popular Adruino Uno R3 which gives me great flexibility in programming of the slider behaviour.

I want to share all the details of the device so the story will continue. Subscribe to follow!
