Documenting the build

Gettin’ ready to document the build.

One of Baker’s requirements for funding me on this project is to find some way to show others how Baker’s money actually did something cool. So, I’ll be doing extensive filming and documentation… Here’s what I’ve come up with.

One of my favorite ways of filming is time lapse and/or stop motion photography, because it just looks really cool. I’ve done stop motion before on my Hexacopter build stop motion. Stop motion is a lot harder than time lapse as it requires you to closely coordinate the building with the filming, making sure everything is in the right place, no hands in the pictures, etc. For a simple time lapse you just let the camera roll at every 5 seconds or so and forget about it. I wanted to go a little above that, so I decided to put the camera on a track and slowly move it as the time lapse progresses. This just gives a really cool effect to the final footage.

Here is what I designed to do what I wanted. It uses skateboard bearings and was designed to be 3D printed with minimal overhang. Notice how it looks a lot like a roller coaster, that’s pretty much what it is. A continuous rotation servo drives it in the back.



Here is the printed result. Both the MITERS and the Hobby Shop 3D printers around were out of tried and tested PLA, so I had to use the hobby shop’s ABS. The bed just isn’t powerful enough, so it came out a little warped. Luckily the imperfections were mainly cosmetic and don’t really affect the performance, it works great.

On a “track”

Still need to make a good track though- my testing ground of a piece of cardboard. Not exactly long enough to get real good effects.
Hopefully I’ll be using this to do a lot of filming. Parts are arriving soon…
