Maybe you’ve come up with some clever camera mounts (and I’d love to feature them on this site). This self-contained solar time lapse build, however,
may be is the most involved and well thought out time lapse photography rig that I’ve seen so far:
According to this Reddit thread, it’s mounted high atop a 30 foot pole, and uses a Nikon D7100 camera (Amazon), a Raspberry Pi computer board for control, and a goal zero solar system to provide power. It’s set up to record the building of a new manufacturing facility. As someone who works in manufacturing myself, I would love the assignment to engineer a system like this.
