A portable shield that can be used in various scenarios where one of them is subversive rebellion on the streets.
This project was created on 03/10/2014 and last updated 2 months ago.
the RGB-123 use WS2812B-10 leds
the datasheet rates them between 3.5 and 5.5v
some guys had trouble running WS2812B at 5V with 3.3V signal levels.
turns out the WS2811 datasheet says that the signal / power ratio should be no less than 0.7.
running the whole setup at 3.7-4.2V from the lipos means that we are well within the 0.7 ratio with our 3.3v signals.
thats why i run them DRIECTLY from the lipos and use no levelshifters or step-up converters anywhere.
the box is just a bunch of JST connectors and fat wires to transport the current away safely.
everything worked out much better than expected :)
