Re: [Paddlewise] LEDs was Night Vision

Putting all 36 LEDs in series would require at least an 80-volt power
source! I suggest a series-parallel circuit with a series resistor in
each leg. See also http://www2.whidbey.net/optoinfo/LED_FAQ.html#Q3.

I'm assuming you're putting them in a hexagon with 4 LEDs on the outside
segments.  Get a piece of that circuit board with all the
predrilled/pretinned holes and put all your LEDs in.  Pull them down
tight to the circuit board.  Just solder cathode-to-anode in a spiral
and connect the outermost lead and the innermost lead that aren't
connected to anything else.
