I created this simple but powerful shutter release remote for my Sony DSLR. With some random junk (or trip to goodwill) you can create one too.
Step 1: Find your items from old computers/electronics
To ON/OFF Buttons (I used a flip button and a push button)
Small Computer Connector (will explain more in next step)
Some kind of housing or enclosure (i used clear, flexible pvc hose - but you could use a film canister or pill bottle)
Sander (or sandpaper)
Step 2: Create your camera connector
This is the actual 3-pin connector that plugs into the camera. We will have to make one from scratch (almost).
This was the most difficult part for me but now that i've figured it out it should take you less time.
1. Find a old computer connector (such as the cable that plugs into a cd-rom for audio). I doesn't matter what size it is or how many pins it has. ALL THAT MATTERS IS HOW FAR APART THE PINS ARE.
2. Cut, Trim, and Sand down the plastic on the connector so there are only three pins left. (trim everything outside the yellow box in the photo for example) I made mine from a 20+ pin connector
3. If the pins on the camera are too wide for connector you will need to widen them a little. I stuck my exacto knife in the holes and twirled it a little to open them up. (widen the holes inside the yellow box in the photo for example)
Step 3: Solder everything together inside of your enclsure
See the photo for the complete wire diagram.
I won't bore you with the step enclosure creation process. Find your case, cut holes in it for your switches, put everything together. If your this far you don't need me to tell you how to make it. I'm sure you'll use whatever materials you have, and whatever process you want. If your completely lost, you can use a film canister and an exacto knife to cut your holes. I used clear, flexible pvc hosing and my swithes are held in place by tension.
Leave yourself a little extra wire so you can mess with it without pulling any wires apart.
Step 4: Plug it into your camera and start shooting burr-free photos, etc.
Sorry i don't have more photos if you get stuck you can contact me and i will help you out.
