  • Overview

I present a detailed description of my DIY cheap, fast, portable, and accurate automated macro focus stacking rail (based on Arduino microcontroller) which can be used with a wide range of photo cameras, and magnifications from standard macro (1:1) to extreme macro (up to 20:1). The same controller can also be used to control a motorized focuser for a telescope, allowing to memorize up to 24 different focusing positions, properly accounting for changes in temperature. To reproduce this project, you need some basic mechanical and soldering skills. Once you have all the parts, it can be built in a couple of days.
