Directional control - an aluminum frame was made that allows the camera to spin 360° on two
different axes giving the camera the freedom to point in any direction.
Trigger mechanism - A clothes pin was wire tied to the camera and the frame. The clothes pin
has been modified to allow a bolt at the pincher end of the pin to extend through the pin and contact
the camera trigger button. The other bolt is used to press against an ice cube. As the ice cube
melts the clothes pin closes and the camera is triggered.
The rock - The rock between the ice cube and the bolt is the adjustment in the timer. The bolt
alone has a small cross sectional area and melts into ice cube rather quickly. The rock gives a
large cross sectional area for contact with the ice cube, thus a slower timer.
Plastic cup - the plastic cup is used to keep the ice cube in place. I found that ice cubes can be
slippery and difficult to hold between the frame and the bolt (or rock). The cup is secured to the rig
by a short length of kite string and is held in place by the force of the bolt. Ice cubes are frozen in
the same plastic cups so they fit in perfectly.
Kite - I had to make the Rokaku kite, the cheap department store kite didn't have nearly enough lift
to hoist my rig.
|Kite Aerial Photography
To get elevated pictures a kite is used to hoist a camera into
the air to take pictures. The point of my rig was to see if I
could get pictures from a kite without spending much money.
I partially succeeded, I got pictures from the kite. I did spend
a lot less than many people.
The people with fancy rigs use RC controllers to run servos
to point the camera, click the trigger and advance the film if
necessary. Many of them are using pretty fancy cameras to
have several hundred feet in the air. I do know how these
things can get carried away.

on the shore is more than 30 feet long.
