2. BUILD THE FRAMES
Using the wood framing dimensions from the Materials list, build
the camera-holding top frame (shown at the top of the photo),
using glue and nails. You can use wood screws, dowels, or pegs
instead of nails if you prefer.
Next, build the mast attachment, or bottom, frame (shown at the
bottom of the photo).
3. MOUNT THE SHUTTER SERVO
AND CAMERA(S) TO THE TOP FRAME
3a. Mount the shutter servo to the
left upright of the top frame (the 1"× 1"
piece). Position it so that its centerline
is at a height of (C + F + 2 washers)
above the surface of the base piece
where the camera will be mounted, i.e.
the combined length of the camera
height (C) plus the length of the servo
arm (F) plus the thickness of 2 hose
Drill 2 holes in the upright with a #25
drill bit (about t"), corresponding to
dimension E. Attach the shutter servo
to the upright with two #6 machine
screws, and fasten it securely with nuts.
3b. Drill a ¼"-diameter clearance hole in the base for the camera-mounting
machine screw, at a position such that the shutter button is directly underneath the servo arm when the arm is fully extended. This distance varies
between cameras and depends on both dimensions A and B.
NOTE: Once you’ve successfully positioned the
servo arm, the shutter
will trip each time the
Insert the 1"-long, ¼"-diameter machine screw into the camera-mounting hole on the top frame. Place
a few hose washers over this bolt before securing the camera. As you tighten the camera by turning the
machine screw, the hose washers compress; this will give you a degree of fine adjustment of the shutter
servo in a subsequent step.
3c. (Optional) If you’re going to add the wireless video camera, drill mounting holes for it on the top frame,
corresponding to dimension D, then attach it with two #8 machine screws, nuts, and lock washers. Take care
to align the digital and video cameras so that they point at the same target.
