[GreenKeys] Building my own power supply

[Harold Hallikainen]

Switching power supplies are difficult to design and build. Relatively
high frequencies and complex magnetics. A great way to blow out a lot of
transistors.

I don't know how tight the voltage requirements are for this application,
but maybe a couple standard switchers in series would work. Here are a
couple 48VDC supplies:
