series]. I plan to use Gecko 202's. Therefore 4.5v*20=90VDC, we know
that the Gecko's only take up to 80VDC so thats my upper limit for my
voltage. The ampers side of things 3.2*4=12.8 @70% duty per Gecko's
doc's =8.96a or call it 9A. Does this all look correct?

a place [ preferably in Canada] where I could purchase the components
off the self to make it. Links to websites that explain building
power supplies in English [ vs electronic-ese]?? Ball park guess's as
to what this should cost ready made? I got one quote back with a
total of nearly $1000USD with shipping.. however I was a bit off on
my first set of numbers provided to them so that might have an
effect.. Does this sound even in the ball park? I had $100ish in my
head when I asked for the quote but then.. I have no idea so..
