Update 12/12/2016

Added the "3D scan.zip"
It includes:
The Arduino Code
The Fritzing File
The Multi Camera IR Control library
The Accelstepper library (Can also be found here: http://www.airspayce.com/mikem/arduino/AccelStepper/)

For the moment the Arduino code i wrote works only with Nikon Cameras ( I tested with my D5500 without any problems)
If you have another camera, maybe you will need to make a little adaption, so take a look to the examples from the library.
Normally this library should work with Canon, Nikon, Olympus, Pentax, Sony and Minolta.
Please don’t forget to chose the mode of your camera where it will receive IR commands.
And also depending on the LED's you use, be sure to have the right resistance (mine are 3V 20mA)
The Arduino code maybe doesn't look perfect, but it's my first Arduino Code and project i did. :)
If there are some problems or questions or feedback, you can always contact me.

Have Fun

Still in progress

A 3D Scanning Table i made for photogrammetry scans.
The process will be, that the table turns, stops and an IR LED sends a signal to a camera and it makes a picture. The number of photos per revolution will be modifiable. So if you take more pictures in one revolution, the resolution of you scan will be better.
For the drive, i am using a 28BYJ-48 5V stepper motor with motor-controller and an Arduino nano. (Everything from china for just a few dollars). The bearings i use are 626-2Z.

If you print the version 2 you will not need any support, but you need to print 3 times the pin for the bearings.
