Nikon Library...

e14 Contributor

Hi, Planning ahead for my next project. A Time lapse dolly.

I was searching around on the interwebs lastnight looking for ideas on how I want the dolly to function.

 

I've pretty much settled on a stepper motor to move the dolly along the rig. And it will be controlled by an Arduino Uno or Atmega2560 (still not sure about that yet).

The control will have 3 rotary encoders (maybe 4) to set:

 

1.Time between stops

2, exposure time/shutter speed on the camera

3. aperature

4. focus

 

Basically everything you can do with an intervalometer + control the dolly motor.

 

But in my Journey through the interwebs I came across a sample of code the started with include "nikon.h"

So I started searching for a nikon library and all I can come up with is a library for nikon specific to the IR reciever on the camera. There was also a few that I found as "multicamera IR control"

I plan on buying a cheap $15 intervalometer off ebay to cut the wire connector off it. I want it to be hard wired to the camera.

 

Will I still need a nikon library to build the sketch? or should I be ok as long as I can figure out the pin configuration of the connector?

 

Thanks

    I am thinking of making a controller for my Canon EOS and have tested out a few things with the camera.  If the Nikon is the same (and I have no doubt that it would not be) then on the side of the camera is a connector for attaching a cable release.  The Canon uses a (standard) small headphone jack for this purpose, one pin being a control voltage the other two are focus and shutter. Just connect one control line to the voltage and either the focus will pull in or the shutter will fire.  I am going to use an optical coupler to fire the focus and shutter so that there is no chance that I over voltage the camera when connecting it to my design.

     

    I have bought a cheap cable release which came with a number of plugs for different cameras.  This kit also has an extension lead to extend the 3 foot cable by another 6 feet.

     

    You would need to look at the number of IO lines that each stepper motor will use and multiply that by the number of stepper motors you are going to use.  Then add the two outputs for the shutter and focus control.

     

    Regarding the nikon.h library, I think that would be used if you were going to control the focus and shutter release with an IR device.  However Canon do have a Windows program that will allow more control of the camera through a USB port.  I have tried it once or twice but now run Linux so have not loaded it onto my PC.  This would give you more control of your camera and would think that it will need a library of some sort.  (Sounds like you might be on the way to writing your first library)

     

    I hope this helps.
