Building A Micro Focus Stacking Rail Using Arduino

When I first showed an micro sized automatic focus stacking rail video, the response was over whelming. Some requested an DIY version of it. Though it only took me about two days, one day for hardware design and one day for software development to build a complete system shown in the video below, it is not that easy to actually write a blog about it. Why? Because it is so easy to design a PCB using Eagle and then solder components on it. Writing a blog and building one with Arduino is kinda tedious because you have to wire them and it is messy.

Anyways, here is the video I shot showing what I did, see how clean it is. While using Arduino might be messy but you will be able to do it. Important disclaimer: I am the designer of MJKZZ Focus Stacking Rail Systems

A Nice Microscopy Setup

Be honest to you, I have neither owned a microscope, nor have I used one extensively. However a recent quest to shoot some butterfly scales at 50x magnification made me build a nice setup capable of doing 50x work using a cheap digital microscope stand. Before this, I have had hard time shooting butterfly scales at high magnification and I was using horizontal setup. First problem is mounting the butterfly vertically, fiddling with specimen holder so that the butterfly is parallel with the objective’s front element, then moving camera back and forth to pre-focus it. Believe me, all of these sound easy to over come, but they are really not. After building the setup discussed here, it is a lot easy and here is one example of it:
