here's myboarduino porkypine.
1 boarduino, 18 100ohm resistors, 6 rgb leds, 6 drinking straws, 18 channels of pwm at about 122Hz. lots of code.
it's really quite beautiful. unfortunately the colors are pretty washed out in the video. maybe i'll try shooting again with a little more ambient light.
there is currently no scripting capability. what you are seeing is commands sent to it over serial from a minicom script.
one has to be careful of bumping one's head on the mega168's current sourcing max. the most you're seeing in the video is 9 channels at 100% duty cycle and nine channels completely off at any one time. last night i had 15 channels at 50% and 2 at 100% and was getting some bizarre flickering. 18 channels at 50% looked ok, though. who knows?
have to play with the resistor values. the greens are super bright, the reds very bright, and the blues much weaker than the other 2 colors. i also figure that increasing the values will give more apparent control over the colors.
and, of course, have to get scripting going.
