I wish I had done this earlier and not when I have 2 more weeks left in the house before I move to a place that does not have a perfect view of Mt. Rainier from the master bedroom window. I've connected this shutter release cable for the 5D to an opto-isolator chip which is then connected to one of the GPIO pins on my pcDuino. Whenever I want to wakeup the camera I set the GPIO pin high for 500ms to wakeup the camera. Then I use gphoto2 to capture the image. The following script will be run at sunrise every morning.
#!/bin/bash
function wakeup {
echo waking up camera
#half-press of the shutter button to wake the camera via optoisolator chip connected to shutter release port of camera
/home/ubuntu/sample/core/gpio_set 7 1
#hold the button for 500ms
/bin/sleep .5s
#release the button
/home/ubuntu/sample/core/gpio_set 7 0
#wait for the camera to wake up
/bin/sleep 2s
}
function takephoto {
echo taking photo
/usr/bin/gphoto2 \
--camera="Canon EOS 5D Mark III" \
--folder=/store_00010001/DCIM/100EOS5D \
--capture-image
}
#write images to card
#/usr/bin/gphoto2 --camera="Canon EOS 5D Mark III" --get-config /main/settings/capturetarget
/usr/bin/gphoto2 --camera="Canon EOS 5D Mark III" --set-config /main/settings/capturetarget=1
#loop 90 times and sleep 120 seconds between each photo
x=1
while [ $x -le 90 ]
do
echo Taking photo $x of 90
wakeup
takephoto
echo Sleeping for 120 seconds
/bin/sleep 120s
x=$(( $x + 1 ))
done
#write images to ram
/usr/bin/gphoto2 --camera="Canon EOS 5D Mark III" --set-config /main/settings/capturetarget=0
The output looks like this:
