PowPi - a switched power adaptor for the Raspberry Pi
The Raspberry Pi is a nice little machine, but like all human
artefacts it has one or two little shortcomings. One such is the absence of a
power switch. Another other is the accidental absence of C6.
C6 is a
220µF power smoothing capacitor. As the Raspi has no power switch,
one tends to turn it off by removing the USB power lead (top right of
the picture). This is much easier to do when one uses C6 to steady ones clumsy
fingers. However, this component is surface mounted and it tends to be dislodged
from the Raspi pretty quickly - as has happened in the top right corner
of my photograph.
