I'm about to go on a 2400 mile road trip including pikes peak and I came up with the idea of getting a time lapse dash cam. I've been meaning to get a go pro lately, but I don't have the cash at the moment. My idea is to mount a decent webcam on my dash and just hook it up to my macbook taking one picture every minute. I don't know much about electronics, but I'm thinking about picking up a cheap 5mp camera and finding some software to run it. Has anyone done anything like this? Should I trust these cheap digital camera's claims of 5MP? If they're anything close to the 5MP camera on my iPhone, it'll be enough. Can anyone recommend any softwares for time lapse photos on a macbook? Thanks!
