3-inch ABS pipe coupler = lens “tube”
82mm UV filter
Pololu Adjustable 4-12V Step-Up/Step-Down Voltage Regulator S18V20ALV set at 7.5v
12v sealed lead-acid battery (12v Lithium Phosphate is better choice)
Nikon SD-8 battery pack (3)
RAM B-sized ball mount
Pic below is how the camera and main flash are attached. The SB-800 is in the ammo case and connected to the camera by an off-camera cable. The inset shows the same diameter hole as the flash cord, drilled at the junction of of the two halves of the case, a little offset to the top half to help keep out water. The photo also shows a RAM ball mount for securing the camera to an external mount.
3-inch ABS coupler cut to size. Note inner ring where a UV 82mm filter will be glued. A short piece of 3-inch ABS pipe is glued to the inside of the coupler to increase the area where it is attached to the case (inset).
The voltage regulator was lightly glued to the case. The power cable is connected to the dummy battery of the Nikon D7100. White paint is to make it easier to align power cable to camera adapter.

Inside of case with all components connected. It crowded but everything fits. Inset shows power for the receiver (signal from PIR) composed of two 1.2v NIMH D-cells and a dummy battery pair in the receiver battery compartment. This is overkill and the receiver power will outlast the camera, but I had D-cells so decided to use them.
The ammo case with a Nikon flash and a window of clear acrylic plastic glued to the case. The thread adapter takes standard 1/4-inch bolts. This can be fastened to a tripod ball mount or a stake. The L-shaped metal is standard stock bent to shape. It is for attaching the flash unit to a post or tree via a lag screw or bolt.
Inside view of flash case of the wired SB-800 flash and a Camtraptions transmitter that controls the two wireless receivers for the SB-28's. Battery pack for the Nikon strobe contains 6 AA batteries (7.2-9v depending on battery type). It is not a simple power booster: It has three pins and an electronics board that sends power only to the strobe. The 4 AA internal batteries of the strobe only power the flash's internal housekeeping when the SD-8 is attached.

Front of Unit. Painting wasn't finished and camera is not centered but that is a matter of a little foam here and there. Yes, the lens filter is dirty.
These stakes are used to mount the flash units if they are not attached to a tree using a lag bolt or a tripod where soil is not deep enough to hold stakes. The metal stakes are made for securing concrete forms and come in various lengths, usually up to 48 inches. They have holes for nails, though a second hole is needed to securely attach the corner brace to the stake. The ball-mount unit (inset) should be positioned lower than the ones pictured so that it is easier to drive the stake into the ground without hitting the ball mount.
