SO I just finished building 4 SpokePovs today, and they're all going to be mounted on one wheel and cleverly programmed so I can have two colors. What I noticed, however, is that my 2 green boards use 3 batteries and are VERY Bright, as opposed to my 2 Pink Boards which only have 2 batteries and are nowhere near as bright. I'm using the same fully charged 1.2V enelopes throughout the boards.
My question is, can I add a third battery to the Pink Boards and achieve a brighter effect without ruining anything? The resistor networks I have on the purple board are rated at 56Ohm
