For Kal

Finally, I got the chance to go to that place again, for
your PKD stuff. This is a CR2032 coin-cell battery
holder which gives you three volts, enough to
light up all the 5 LEDs. But I am not sure if
the green LEDs needs to be lighted up as
well. Still, it beats opening the grips to
change the stack of coin-cell batteries
which could also somtimes give you
reliability problems when it is
shaken too much
