Glo-Control MkII

This design uses one of the modern switching regulator IC's
(LM2576) that are available these days, these work like a speed
controller by switching the output on and off very fast (52Khz)
and smoothing the output to produce the desired DC voltage. The
advantage of this is that the regulator dissipates very little
power and hence makes the whole thing more efficient.
