Hmm, well I just took a quick glance at the CHDK forum ([link]) since I would have suggested using that piece of firmware to "hack" that camera, to make time lapse easier, but I'm not sure that camera is supported.
But, in terms of not needing to replace the batteries, I assume it has a power in kind of adapter? My Canon PowerShot SX100 IS didn't come with a power adapter, but I was able to buy on at Radioshack for pretty cheap. Just make sure it spits out the right voltage, and has the right adapter, and all should be good.
Yeah, it does run on 4 AA's. I'm gonna go with that adapter idea. As for the connecting the camera with laptop - what I had in mind was if it would be possible to route the saved pictures directly to the laptop's hdd. I assume that's what you had in mind as well? Cause the camera has the required software (hacked...) in terms of taking pics in intervals (ranges from 10s to 10 minutes, as far as I know). Anyway, thanks for the input, I'll ask around shops about that cable Cheers!
Oh, as for it automatically moving files... I can't say for sure if you've hacked the software on the camera
...but usually cameras just mount as file systems. That means you can copy images off the camera to your computer and then delete the images on the camera. Which I realize is stating the obvious. The trick is that you can write a batch file/ shell script that does it automatically
Although, it would be easy to just buy a 32 GB memory card from Amazon Basics and have it hold all of the pictures. I mean, you aren't really looking to take all that many.
