Below you'll find a quick step to step on how to trigger your camera with your keys!
Step 1: Materials
1) DSLR - I used a Canon 5D Mark 1 with the old intervalometer connected on the side. I do not know what other cameras would have the capabilities to do this but I will research soon.
2) Metal object - Something that is at least 2-6mm wide and conducts electricity. I used a key, and a 2.5mm audio jack (found on earplugs).
Step 2: Explore Your Camera
Now you need to find the part on your camera where an intervalometer would connect. For me, it was on the left side of the body of my DSLR, with a little logo of a controller and cord. Inside it there should be 3 little pins poking out of a hole.
*I do know that lots of modern cameras have an 2.5mm port the same as an audio jack. To view an Instructable that has a remote trigger like mine, for those cameras go HERE*
Step 3: 3 Little Pins
If 2 and 10 are both in contact with conducted, nothing happens.
If 2 and 6 are in contact, a photo will be taken.
If 6 and 10 are in contact, camera will focus.
Step 4: Take Photos!
Thanks for reading this Instructable. It's my first one and I would love feedback.
Feel free to use this however you want, as long as there is no forgery.
