Nikon D90 DSLR camera trap: Almost a year in the making

A new DSLR camera trap

A Nikon D90 and battery pack with a 50mm ƒ 1.8, SB400 flash and a Yeticam board in a Plano 1460.

Last year in September, I made a post about a Nikon D90 with a 50mm ƒ1.8 lens and a SB-400 flash in conjunction with a Yeticam board in a Plano #1460 clear case.

It was in pieces at the time and sat on my bench until last month when I decided to finish it off. I have two sets but will test this one first to see the results. The SB-400 has four AA externals plus two in the flash for (six). I use either Lithiums or Enelopes.

The D90, battery pack and SB-400 sits nicely in the case but a relief hole was needed on the side to allow a little more room for the shutter cable. I found some ‘Meike N3’ electronic shutter release for Nikon (90 degree plug) and just cut the button off and attached the wires to a Yeti board. I used a piece of  ‘plastic tubing’ and a 10 Baht coin and ‘gooped’ it all in sealing the tube.

A 3” X 2.8” X 1/8” aluminum tube is used for the snorkel and a 77mm filter is gooped on. No other modifications are made to the case and everything fits perfectly. The Yeticam board is set in the vertical position and an EOS chip was installed.

A huge ‘elephant proof’ aluminum box was made up to protect the cam. As this one is really large, I had my welder attach a plate on top at a 45-degree angle to keep the jumbos at bay by not allowing them to get a grip on the top.

Four 3” X 3/8 stainless lag bolts set the cam tightly on a large tree and I can use two 10mm (3/8”) Python locking cables for extra security.

In the meantime, I added two Nikon SB-26s with 6-volt externals in ‘elephant proof’ aluminum boxes run as slaves. The flashes were modified to take straight 6-volt packs and plugged into the pos. and neg. pins as shown. Real Nikon battery packs cost a fortune. This is an alternative that works very well.

The ‘elephant proof’ boxes were made for the SB-26s that have flash diffusers gooped on the front and 40.5mm UV filters on the back in line with the light sensor.

I also built a small ‘Achiever’ slave flash with 4-AA externals in a clear Plano 1499 case. An old 1020 ‘elephant proof’ box was recycled for this flash. This will be used depending on some locations.

I look forward to setting this cam and slaves. I probably will put it close to where I was charged by that bull gaur.
