This should be called Vers III, since I've ripped up the layout twice now and started over, each time with a different design. I'm about to send this gerber off to Seeed, wait 3 weeks, then get to soldering. I'll be doing the software during the wait time. Wish me luck!
For those interested, what this does is to simulate a rotating beacon for a miniature lighthouse. The LEDs are pulse modulated so that as one LED is increasing in brightness, the one next to it is at full brightness, and the one next to that is decreasing in brightness. I plan to allow programming the overall brightness and rotation rate by shinning a spotlight on the solar panel (at night) in a series of flashes that the processor will interpret as programming commands, kinda like morse code only really simple. The lighthouse will be floated on my pond on top of a simulated rock - a well pump cover with 1-gallon plastic bottles at each corner for floatation. My last try at this resulted in my contraption sinking but I managed to salvage the lighthouse before it went bye-bye.
I'll be back to this thread to report on the results, with pictures & movies. Comments/criticism/suggestions welcomed.
