Portable Digital Timelapse Photography? 19
Bakajin asks: "The posting about the camera speedometer hack reminded me of my interest in portable time lapse photography. I wondered if the astute Slashdot crowd can make some suggestions for a very portable digital time-lapse system. I was initially thinking about a PDA connected to a small web-camera. I'll hack my own code if I have to, but I'd prefer to have something off the shelf or not involving too much work. Any suggestions on the PDA/camera/software combo or any different system?"
Possible (Score:1)
For portable units, the main issue is power management. However, it is possible to program a PDA to wake up at a particular time, run an application, then got back to sleep. The camera is also a problem for power management as it should wake up when the PDA wakes up, (this wouldn't work with my Olympus).
I don't run Linux on my PDA yet, but I have an IPAQ, which is very programmable and supports USB. It could do the job withm dare, I say it, WinCE (the standard system and the development kit) and just sending stuff down wire. You *must* send it to sleep after each photo though if you don't have external power, otherwise it will die after about 2.5 to 3 hours (less if you download the image from the camera).

The jPhoto Linux USB driver should do the trick, see www.linux-usb.org/devices.html [linux-usb.org], http://jphoto.sourceforge.net [sourceforge.net], or the tech. spec. pdf [usb.org]

They both include a nice time lapse feature, which keeps the pda powered down as much as possible to avoid draining the battery.

# comon, do i need to comment that?
# you need to touch count.file and on the topline insert the number
# 0 for instalation purposes and thats it
# 1: zork is used to create a loop so the program continuosly runs until
# 1: killed
zork=0
while [ $zork = 0 ]; do
#
# 2: check to see if count.file exists, if not, create it and insert the
# 2: number one at the top
ls count.file &>
if [ $? -ne 0 ]; then
touch count.file
echo 1 > count.file
fi
#
# 3: the variable count is used in naming pictures and count.file stores the
# 3: current number to use
count=`/bin/cat count.file`
#
# 4: if the count is less then 1 set it to one (used to initialy set the
# 4: variable to one and to never change it from there, a simple count = 1
# 4: at the top would not work, because you would overwrite old pictures
if [ $count == 0 ]; then
count=1
fi
#
# 5: tells gphoto to take a picture and save it as #.jpg, when that command
# 5: has completly finished gphoto then deletes image #1 which is always
# 5: the number of the image on the camera (be sure to delete all images off of
# 5: the camera before using this program
gphoto -p $count.jpg ; gphoto -d 1
#
# 6: add 1 to the current value of count
count=`expr $count + 1`
#
# 7: write the echo of count to count.file for future recall
echo -n $count > count.file
#
# 8: set the following value (in seconds) for how often you want to take
# 8: pictures
sleep 1
echo 1
sleep 1
echo 2
sleep 1
echo 3
sleep 1
echo 4

(ignore this, fucking slashdot is bitching about to few characters per line, there's nothing i can do about it without murdering my script except to sit here and rant and rave hoping to get this post to go through, two few characters per line, 25.1? what kind of bullshit is this? i mean, this is preventing me from making a decent post, and im mighty pissed off, slashdot needs to find a better way to deal with trolls because they are now disabling the site for regular upstanding users)

I've got a Coolpix 995, and it takes GREAT photos. In case you were wondering about just long exposures... here's a self portrait [photo.net] which shows a fairly long (4 second) exposure.

Nikon MC-EU1 - SUCKS!!! (Score:2)
More time spent, tried automatic mode on the camera (I always use Manual), no joy...
Turns out the engineer who designed this thing is a mornon, he built in a 2 MINUTE minumum interval into this thing. There is no obvious or sane reason for this, the camera only takes about 1.5 seconds between pictures, what the heck was the imbecile who designed this thing thinking???
Now I reconsider the whole Nikon experience... perhaps now it's time to switch to Canon, or Kodak??

Those X10 cameras can do it, sort of (Score:2)
The wireless receiver plugs into a USB port and the bundled software (actually you have to download it) allows you to record time-lapse images.
It's been a while, it might only run as slow as 1 image per second or per minute, but I know I found it entertaining to play with for a while.
Now, like so many other cool toys, all the X10 stuff sits in a package on the shelf.
You can see one time-wasting use I had for the wireless camera (and thus you can see the limited image quality), at http://www.robot-news.com/tele-rover/ [robot-news.com] (or just go straight to the animated GIF at http://www.robot-news.com/tele-rover/animated.gif [robot-news.com]) .
