As a an avid photographer, I carry two things on me constantly - my phone and my camera. Once I discovered there was a way for me to use my iPhone as a camera remote with the DSLRbot app, I knew I could easily build my own remote trigger for my DSLR with Radio Shack parts.
Step 2: File Down the LEDs
Step 3: Glue the LEDs together
To mix the epoxy, gently squeeze out of the tube on to a piece of wood or cardbord. Then, snip the end of a popsicle stick or coffee stir to thoroughly mix both parts of the epoxy together.
Gently apply a small amount of epoxy to the LEDs' filed down edges, and allow to sit for 30 minutes.
The LED's leads are wired in reverse parallel, so you need to file down the same side on each LED. The long positive lead from one LED must be wired to the short negative lead of the other LED, and vice versa. Please see the schematic attached to this step.
