The Pi-Pan is a pan-and-tilt device for the Raspberry Pi camera. mindsensors.com distributes the kit and their website has instructions for an earlier version of the device.
This instructable shows you how to assemble the kit using the newer version of their parts and the newer version of the camera module. The distributor's website has the necessary information about installing the hardware and software.
Step 1: Attach Plates D and C
Plate D is the L-shaped plate with two square holes. It fits on the side of the servo where the wires are attached. Screw it on so that the wires protrude into one of the square holes.
Plate C is the other L-shaped part. Screw it into the servo on the side opposite the wires.
Step 2: Attach the Second Servo
Mount the second servo between plates C and D and perpendicular to the first servo.
Thread the servo wires through the slot in plate D.
Step 3: Plates B and A
Screw a horn into the white side of plate B, aligning the large holes.
Tap the camera screws into plate A to make it easier to mount the camera.
Remove the camera screws then screw the camera onto plate A.
Important note about camera versions: The mounting shown is correct for the original Camera Module with its cable extending upward. But if you mount the Camera Module V2 this way, the image will be upside down.
Some camera software allows you to flip the image vertically and horizontally to correct for this, but I chose to mount mine with the cable extending downward. So I screwed my camera into the black side of plate A.
Plate B mounts at a 90-degree angle to plate A. Slide the 3 prongs of plate B into plate A then screw through plate A into plate B. The Camera Module V2 with a downward cable is shown in the last picture
Press plate A's hole onto the servo shaft then screw drive the screw into the end of the shaft.
Attach one of the remaining horns to the other servo shaft and mount the completed assembly. In the last picture, the horn has been glued onto a standard plastic case.
