A web controlled macro rail that can remotely control cameras by Wi-Fi to take focus bracketed photos.

With this project you can control cameras placed on a focus rail (the hardware can all be bough for cheap from Ali Express, links provided in the project page). It can control cameras by IR or Wi-Fi.

The project code can be used for other projects where wirelessly triggering a camera is desired. It can control Sony, Olympus, Panasonic and Canon cameras all by Wi-Fi. I will try to add support for other cameras as well, but I need to have them physically in order to test. I would like feedback on the GitHub project page,  to know if it works for your camera or not.
