Come on! You guys are hardly trying!
Here's the "eyes" of a robot I built for a convention that was done on a Thursday night with the convention starting Saturday morning. The rush was mostly just a case of running out of time.
PCB cut with a dremel, traces drawn with a sharpie. You'll notice there are no resistors for the red pins on the RGB LEDS because it turned out red wasn't one of the colors being used. The ground line is across the top.
The whole thing is driven by an Arduino Lilypad (I was happy to find a use for the little guy). The Lilypad doesn't actually have enough PWM outs to drive this, so I had to "manually" PWM the LED pins in software via the regular outs. This actually worked out really well, and while the hardware may not be pretty, I'm happy with the software. Two adjacent LEDS are on at a given time so it can "look" left, right, forward and squint by dimming to a different darker color. There is an extensive script to make the pattern seem natural.
When I get some spare time (right) I should be able to get the whole thing down to a single board, LEDS, power supply, charger and MCU.
Until then, I'm living with it. It works great.
