Made a cheap & easy remote shutter release for my Canon Rebel T3 camera using just an old cassette recorder microphone that has a on/off remote switch & the smaller 2.5mm plug & a small nut. just super glue a small nut on the 2.5mm plug so that the plug inserts about 3/4's of the way into the camera's remote jack. Put camera into bulb mode & when you turn the microphone's switch on it will take as long as an exposure as you want until you turn the switch off.
