I knew this day would arrive: you can now buy strings of RGB LEDs for Christmas decoration that cycle through different patterns of colors, and you can now control them with a microcontroller to do whatever you want them to do. Info is here. I’m delighted.
RGB Christmas Lights
Gotta have ’em!
this reminds me of the programmable light board that you built, but in 3-D what a great thing.
I wonder if they could be made to correspond to clock time so you would get color changes at each hour etc.
Holiday greetings – B.
Once you had a microprocessor controlling them, it would be entirely feasible to make them display different colors and/or patterns based on the time of day. I’ve thought now and then about building some sort of clock with colored LEDs, but haven’t yet come up with a design I like well enough to actually build. I’ve long loved the idea of making clocks that use color, ever since seeing a clock (at Paper Traders in Eugene, I think) that used some sort of mechanical arrangement of lights and colored plastic to create a display that slowly changed color. I’ve also thought that it would be neat to use a computer projector to cast some sort of time-based display on the wall.
Makes me think of Linnaeus’s flower clock…
