Wakelog Pictures

Level: Intermediate
  • OS X

This page describes how to set up your iSight enabled Mac to take and upload pictures on wake.

Download isightcapture and place the executable in /usr/bin/.

Download sleepwatcher and run both installers. Sleepwatcher is a dæmon. When the computer wakes, it iterates through all user accounts and checks for a .wakeup file in their home folder. If .wakeup is found, it runs it as that user

Make sure you have password-less uploads setup for a ssh server via shared RSA keys. On that same computer create a directory for the images to be uploaded to.

Create the following file called ~/.wakeup and make sure it is executable (chmod +x ~/.wakeup).


date=`date +%Y%m%d_%H%M%S`;
echo `whoami` woke at $date >> $LOG_FILE;

# wait a bit
sleep 1;
# capture an image
isightcapture $date;
# wait a while
sleep 60;

# check for internet connectivity
online=`curl | wc | awk '{print $1}'`

if [ $online -ne 0 ]; then
	# attempt to upload images
	echo attempting to upload images >> $LOG_FILE;
	# change the following two lines as needed
	scp ~/.capture/queue/*.jpeg;
	scp $LOG_FILE;
	mv ~/.capture/queue/*.jpeg ~/.capture/uploaded/
	# no connection found
	echo no connection found >> $LOG_FILE;
