Build your own remote control to operate your camera's shutter with a few inexpensive electronics.
Having a remote on your camera allows you to take pictures without setting the timer or having someone else press the shutter button. If your camera did not come with one, you can build your own using some easy-to-find electronics. Remotes can be helpful when taking self-portraits or wildlife photos, and in reducing camera shake.
Instructions
1. Remove the round, rubber sleeve off the earphone jack. The headphone jack is threaded, so turn it counterclockwise to loosen the sleeve and slide it down to reveal the three connectors. The top part of the connectors is for the left channel (tip) while the middle part is for the right channel (ring). The bottom part, which is the longest, is for the ground (sleeve).
2. Connect the green wire to the top part of the jack by soldering it. Solder the red wire to the middle part (ring) and the black wire (ground). Slide the sleeve up to reassemble the audio jack. Turn it clockwise to tighten.
3. Open the project box by removing the screws and prying open the casing. Make three holes to accommodate the two momentary delay switches and the toggle switch. Make another hole for the telephone wire. Make the holes with an electric drill. The upper part of the project box should contain one hole to house the toggle switch. The lower part should contain two holes side-by-side that will house the momentary delay switches.
4. Attach the toggle switch and the momentary delay switches to the box. Secure the switches and tighten the washers that came along with them.
5. Solder one connector of the toggle switch and one end of the momentary delay switches to the red wire. Solder the other end of both switches to the black wire. For the toggle switch, decide which side to solder to the red or black wire because it will determine the on/off state of the bulb. The switch is used to release the shutter.
6. Solder one of the connectors of the remaining momentary delay switch to the green wire. Solder the other one to the black wire. This switch will be used for auto focus.
7. Reassemble the project and begin testing you shutter release gadget with auto focus.
