Beacon3

Beacon3 will be a beacon for the top of our flag(less) pole for Burning Man 2011. It will be simpler than Beacon2 as time is limited to get it done, but we want a brighter beacon.

Ideas

• Less LEDs, but much much brighter. Thinking either a triangle or square with a 1, 3, or 5W RGB LED (either integrated or discrete) on each side.
• Planar PCB that fits onto the spindle, then LED PCBs that plug in vertically seems like it would work
  • LED PCBs may need heat sinks, which could fit into the middle space around the spindle
• Single MCU this time, as there are fewer LEDs
• Same enclosure as Beacon2 can be used to save time, just remove PCBs and replace with these
• Same light sensor and (lack of) charging circuitry as Beacon2 can also be used
• Having a little remote that would make the beacon extra-noticeable when a button was pressed would be cool
  • Something like the Nordic FOB from SFE
