MrinnovativeDSLR-Camera-slider-Using-Arduino
Hello friends in this video I have made a 2-Axis camera slider,
by using arduino stepper motor and some aluminium extrusion profile.
A rotary encoder and 0.96" oled display used for user interface

I have used the 12mm birch wood to made this side blocks, the dimensions are 60mm on top
and 80mm on bottom, and have 20mm grove at the top center,
in this grove we can place our 20x20 alu. extrution profile.
This is the main part of our project this are the 20 x 20 Alu. extrution the length is as per your need means how long you want to travel camera you can keep length as per that.
I have used two aluminium extrusion of 20x20 cross section size you can use 20x40 size as well 
This is the camera slider platform
it have four V shape wheels on the all four corners this wheel fit in the grove of 20 x 20 alu extrusion profile.
I made this platform using 4 mm wood there is also a provision for nema 17 stepper motor.
this motor will pan the camera in 180 degree horizontally
This is the control unit box which I 3D printen in PLA filament
its size is 75 x 55 mm I have placed my PCB inside this box and I placed a rotary encoder and
small OLED screen on the cover of this control unit box
This rotary encoder and small OLED screen is helpfull for user interface and to display data on the screen
