Chuck's Technical Notes
This is definitely a work in progress, but here are some tools and techniques that I use for creating Time Lapse videos.
Gathering Images
I have 2 CHDK capable Canon PowerShot Cameras, a S3 IS, and an A560. I typically use CHDK uBasic intervalometer scripts that will just click the shutter forever at some given interval (5-30 seconds, usually). For the astronomy images, I add a command that adjusts the shutter speed to 65 seconds for each shot.
Linux + a Camera
I have a few linux boxes, my current favorite flavor is Ubuntu (7.10)
Digital Camera control using gphoto2 http://gphoto.org
Gphoto/libgphoto is a great linux tool which allows communication and control of a pretty good variety of digital cameras.
Here's information about cameras that gphoto2 can control to do remote image capturing http://www.gphoto.org/doc/remote/
Webcam monitoring using motion : http://www.lavrsen.dk/twiki/bin/view/Motion/WebHome
'Motion' can do time lapse and motion detection using any video4linux capable device. This includes many types of webcams or video capture cards. Most of the beavercam images were taken using a video capture card and a security cam. Although before I got the security cam, I just used an old video camera connected to the capture card. I 'weather proofed' it by mounting it on a little platform, and placing a small aquarium on top of it. High tech, I know... There's a pic at the top of the BeaverCam page.
