Interesting BTS of Building an Arduino based Motorized Camera Rig:

Kurt Schaefer over on his Blog, Retro Tech Journal / Tales of Creation and Recreation, has posted how he went about building an Arduino based motorized camera rig. After having mixed results playing with a dead inkjet printer, Kurt looked to making motion happen a different way.

Arduino

I started to think about what a serious system with substantial time investment would have. It could be bigger and have at least two-axis camera motion. It would need a bunch of software with some way of key-framing the camera motion, maybe an LCD display, maybe a pendant control for stepping/snapping frames without jiggling the camera. What else? A way to power and auto-trigger the camera for time lapse. All in all a much, MUCH bigger project. OK, if that’s the end goal, what’s a good first step? I’m always wary of physically big projects. As the size goes up, costs go up. Big projects are harder to get into/out of the car, take up more workbench space, and ultimately collect dust in a bigger way. If I can fit a project into a single project box, life is simpler.

So instead of embarking on a large two- or three-axis rig, I decided to build a very small one-axis rig. Heck, I already had a small one-axis slide. This way I could get my feet wet with the software, LCD, motor controllers, and all the other fun stuff, but without as much schlepping.

Crystals Time Lapse

I decided to try shooting a time lapse of crystals growing. I shot this over 10 hours at 1 frame every 2 mins. The code moving the stepper motor/shooting the frames is running on an Arduino Nano.

It was over-exposed and didn’t have great focus, but the kids thought it was cool. Success!
