Final testing + pictures



I finished the wiring harness tonight and took careful notes for the production version, which will be significantly less tedious to connect together.

All 32 pixels are working perfectly, and I stretched them out in the front room for some photos. Camera is a Canon Digital Rebel exposing for 1/20 @ f/14.

I built up a test sequence which lasts about a minute. Primary colors fade slowly into each other on the first layer and white bars chase from left to right on the second layer. In the pictures you can see the bars at different locations on the string.

As I mentioned in an earlier posting, the circuit boards are mounted to the underside of each jar's lid. If the jars sit normally on the countertop, the LEDs fire directly downward. You can see in these photos that as long as the LEDs aren't pointing directly at the viewer, the diffusion introduced by the opaque plastic is very, very smooth. However, the individual LED chips are bright enough that the separate colors are visible if you look at them directly.

With any luck, the rig will be in the air tomorrow night and I'll be able to post pictures and proper video clips then.
