Hi all,

I am looking to build my first ever SLR camera trap out of my old D200. After many months of regular trailcaming and finding some great spots i am craving to add my photography background to the mix!

I have never done any breadboard builds or Arduino programming but love to challenge and learning experience. I have found these two instructables and I am wondering what you all suggest to start with and what I would be best off with in the long run! Is it worth going with Arduino and having the ability to program? Or should i just go with a simple breadboard build?

https://www.instructables.com/id/Simple-PIR-DSLR-Camera-Trap/

Ideally I am looking to take 3 or so photos each time the PIR detects movement!

I would really appreciate some of your guys knowledgeable advice. This forum has already been so informational and inspiring!

Thanks!

HI Geoff. Welcome to camtrapper.com.

The Arduino is a good starting point to learn simple script writing. There are many web sites dedicated to teaching the basics of scripting with the Arduino. The only downside to the Arduino is the power draw. Especially the Arduino Nano shown on the thezhut.com page. The USB circuit in the Nano uses quite a bit of power even when it is not being used. But for experimenting and learning, it works well. There are many other models of Arduino that all use the same IDE. One tip, each web page you listed use a two wire connection to the remote jack on the camera. That will work with a Canon but will not work with your D200. The Nikon requires a connection to the metering (focus) line and the shutter line. So, three wires.

Hope this helps. Good luck in your build. There is a wealth of information here and many knowledgeable members that will be happy to answer your questions.

-jeff

The D200 may not need three leads for triggering.

I have used a D200 and D3200 for a few winters in Finland and those worked well by joining the metering and trigger into one. I have used both cheap PIR's and industrial grade light ports with "transistor" output.

I am also interested in getting 3 triggers / 1 trapping, but I am not sure how to do it yet.

So, you want to trip the camera shutter three times for each motion event? Probably the easiest way is to use one of the many Arduino compatible boards and write a script to make the camera do what you want. Use a board without the built in USB electronics to save power.

I confirm what Jeff wrote. All Nikons with a cable as in the picture require not only three cables but also the correct order (first focus, then shutter) to take a picture. I don't know how entry level models. Tomorrow D3300 comes to me. If it interests someone, i can check and write.

That is the DC0 connector type which should be all the Nikon FX cameras except D600 series and D700 series + works on DX D200 - D500 series.

DC2 is the Nikon 3000, 5000 and D7000 series + D600, D610, D750 and possibly D90 can't remember.

Hope this is useful in picking a cable

I should also check out the low power consumption arduino pir Instructable as massive power saving vs many standard tutorials. Think it was 70% power save so gave days of use in hibernate mode

That's my Instructable, I won second place in their sensors contest a few years ago. Fun to build and learn how the technology works, but do yourself a favor and purchase a commercially available sensor (cognisys, trlcam, or camtraptions). It will be cheaper in the long run and you will have a much better, frustration-free solution.

I lost to a high school kid who put an Arduino with a camera on a weather balloon and sent it up to take a picture of the curvature of the earth. Pretty cool.

Well it was a great article Stinky.
I can second how good Camtraptions have been and the Trlcam and Cognisys stuff looks equally impressive.
