I used this on a Canon A480 to take periodic pictures while the camera was hanging from my Kite. The pics didn't come out well when I tried it, I think it was just way too windy. I'm sure I'll have another go later though.

The firmware is pretty neat though. You can just load it off SD card when you want to and not modify anything on the camera.

I really wish I could do some more hacking with this and some Eye-Fi cards. I had a research project focused on mobile group photography, Mobiphos (http://nirmalpatel.com/research/mobiphos.html) that I really wanted to use on high quality point-and-shoot cameras instead of just camera phones.

i'm sure you know but, fyi, canon a480 is not that high quality p&s camera.

I didn't intend to use the a480. These tools work on other Canon cameras.

I used this to nice effect on my Canon A590IS. It allowed me to overcome the 15 second maximum long exposure to get at least 64 seconds.(http://www.flickr.com/photos/allseeingcuttlefish/3469157079/).

I keep hoping someone will create a similar project focused on Nikon cameras.

For those interested - I wrote a series on how to make HDR photos and mentioned using CHDK to do that with RAW files: http://paulstamatiou.com/how-to-get-started-with-hdr-photogr...
