Laser-cut R/C rig for S100
Up until now, I've been doing AutoKAP with a fixed rig and a CHDK-enabled camera. I point it in the direction I want to take a picture, start the intervalometer, and fly the kite. As many of you know, this procedure works quite well. I have a lot of radio-control gear laying around, though, since before KAP I was into R/C airplanes and helicopters (still am, actually, but not as much with all the new FAA regulations), so I figured why not give an R/C rig a try?
I also have experience with CAD, both from work and because I like to design and build my own R/C airplanes. I've been using FreeCAD, an open-source CAD program. Designing the rig didn't take long, and getting it laser cut from 3 mm liteply was only $17, including the material and shipping too, from Manzano Laser Works.
Building it was also simple. It didn't take long to glue the whole thing together, mostly with gorilla glue.
Here's a video overview of how it works. It has pan, tilt, and shutter control, plus a switch to turn the video downlink on and off from the ground to conserve the battery.
I got a chance to fly it over the weekend. It worked really well! Here is a video from the downlink. This is the kind of picture I see from the ground on my monitor.
Here are a few of the best pictures from the flight.
