A cable shutter release is one of those camera accessories that for me, isn't entirely necessary, but is something that may prove useful to have, e.g. for if I ever get around to taking photos of the stars. I wasn't going to fork out the money to buy one, especially since it was is something that I don't absolutely
need, and being a photographic accessory, they don't exactly come cheap (but then again, what photographic accessory does?)
So, I thought about building one myself, and looked to see if there were any instructions. It turns out that a cable shutter release mechanism is actually very simple, and it wouldn't be overly difficult to build one. In fact, if you have even the slightest bit of soldering skill/electronic skill, you should have absolutely no problems with building one. And it comes cheap too. The parts, from a local electronics store, came to a total of just A$6.35, (~US$5.50).
So how do you build one?
Firstly, to read up on how a cable shutter release works: click
here
And then try
here and
here for the instructions.
And then using the information from the sites listed above, I created this:
This is my circuit diagram. Operation is very simple. Press the blue button for AF. Press the red button for the shutter. And for bulb mode, flick the switch to open the shutter, and when I'm done with the exposure, flick it back.
These are the parts
This is the completed cable release.
