Why not just unhook it :)

AFAIK (my technical college time is 20 years behind me now) You need to
feed a led with a current of aproximity 15 mA (should have to look a
datasheets for this). Depending on the color of the led the tension could
be in the neighbourhood of 1.2 V
So the value of R would be
R = (UHD - 1.2)/15 mA

Is this a final breathing LED circuit? and i'll build it ;) Has

Homage to apple, such a simple circuit, such simple idea's such ground
breaking effects

One question about the below circuit, how does the slow charge of the
cap happen, the orignal point of putting the resistor before the cap was
to have a slow increase and a slow decrease through the LED draining the
power.
if the cap has no resistance then won't it reach almost full charge of
