Lights, camera, actionPosted: 2005-July-26
I worked on doing some tests of the lighting circuits. I am working on a bike for Burning Man and I'm going to use the same lighting technique, so I got a chance to try out what I want to do. I started with the red/blue 3mm LED's and the green 3mm LED's from LSDiodes.com. I decided to wire them in opposing pairs so I wouldn't have to space them as close (I figure the glow from an LED travels about 1 foot down the polyethylene tubing, so I can get away with spacing them out every 2 feet if I make a pair that shine away from one another.) It really wasn't too bad at all … here's the photo essay:
The next step was getting the ribbon cable inside the 3/8" inside-diameter tubing. Initially I tried just stuffing it in but it ended up being all floppy inside the tube. I bought some 1/4" outside-diameter tubing, taped the ribbon cable to it, and then stuffed it through. It works a lot better for two reasons: first, the ribbon cable lays flat, and second, the light assemblies are hard to push down the tube — I was using a piece of stiff wire, but with the additional small tubing, I can just guide it through without a push-rod.
