Kite Aerial Photography (KAP)

Step 2 The trigger - materials

Objective:
Battery operated motor turns a toothed cam which depresses a plunger to activate a camera shutter; A basic mechanical intervalometer.

Method of Attack:
Since electronic timers were out, I had a blank slate on how I wanted to approach assembling the trigger. After a brief review of of my options I discovered that there are unlimited ways of making a trigger assembly. This is just one. Actually this one in particular had maybe too much thought put into it. I wanted the largest possible audience to participate. This instructable will show you a simple method to achieve timed photographs, automatically, with recycled and everyday items.

It was time to get dirty, and creative. I compiled a few collections of cd spindles to free up a spare. The paint sticks were free from the hardware store. The pen and pushpins were liberated from the tyranny of the office supply cloest. The toy bunny was a gift from my sister, to which I thank her by mutilating said gift. As for the casette? Vhs is a relic from a bygone era best forgotten. There will no tears shed for it's fate.

.
Almost everything used for the trigger was recycled, found, or free:

• CD spindle
• clicky pen
• push pins (around 30)
• paint sticks used for mixing paint
• nuts, butterfly nuts, washers
• 90 degree angle bracket
• 3 x 50mm (2") steel mending plates
• vhs casettee
• electric motor from kids toy
• camera mount _{(from old tripod)}
• plastic tubing _{(can use washers or plastic spacers instead)}

tools needed:

• glue gun
• hobby knife
• pliers
• screwdrivers
• safety goggles _(seriously)
• rotary tool _(optional)

the methods used are specific to the materials on hand, your project may differ, improvise as needed.
