Prototyping an arduino based macro focus stacking contoller.

Stackduino is an Arduino based controller for automating focus stacking.

A stepper motor moves the camera/ subject between pictures and the controller sends a shutter signal to the camera to take each picture. For safety, the camera is electrically separated from the controller using opto-isolators.

Features:

Set step size Set number of steps Set pause time between steps Toggle whether stage returns to start position at end of stack Select unit of measurement for steps: microns, mm or cm Manual fwd/ bwd control of stepper motor to set up the shot Select speed of stepper motor Automatically cancel stacking if a limit switch is reached
