Step 1: Parts
-Film Canister: This will serve as the body for the controller, after all, it is going to be used for taking pictures!
-Two-Way Switch: I had an old electronics kit from RadioShack that I took it from.
- 2 Submini Pushbutton Momentary Contact Switches: Purchased at RadioShack for about 3 bucks. Only pieces I had to buy.
-3/32" Stereo Jack Plug: I'll discuss this in the next step.
-Three Identical Lengths of Copper Wire: However long you want the cord to be.
-Meter w/ Continuity Test: Will come in handy when making connections later.
And then, some basic parts:
-Utility Knife or Scissors
-Soldering Iron and Stand
-Rosin Core Solder
-Heat Shrink Tubing
-Drill with Small Bits (I used a 3/16" bit to drill holes for the pushbutton switches)
Step 2: Let's Start!
My graphing calculator came with this cable for connecting 2 calculators together, and I figured that I would probably never need to do that, so I cut it in half and stripped the three wires inside. Make sure that none of the wires are shorted due to a cut in the insulation! You'll ruin the whole thing.
Also, before continuing, plug this jack with the stripped wires into your camera and power it up. Experiment with shorting different wires to figure out which two you have to connect to make the camera focus (if it's on autofocus) and which two have to be shorted to take the picture. One wire should be common to both of these connections. Make a note of all this!
