Re[4]: [Discuss-gnuradio] DC-DC converter

[Jared Harvey]

Hello,

I've  been  bread  boarding  a  DC  to  DC  charge  pump. It currently
function's,  but  could  be optimized a bit further. Attached is a PNG
produced by gEDA's gschem.

Some  notes about it's current status. It accepts +5 referenced to GND
and  generates  a  regulated  33v  referenced to GND. Under no load it
produces  34v  and  with a 16k resistor for loading it produces 32.5v.
All  caps  are currently .1uf 50v electrolytic. I believe it's cost is
less then $10, most parts can be obtained at Rat Shack.

Best regards.

Albert Einstein, when asked to describe radio, replied:
"You see, wire telegraph is a kind of a very, very long 
cat. You pull his tail in New York and his head is 
meowing in Los Angeles. Do you understand this? 
And radio operates exactly the same way: you send signals 
here, they receive them there. The only difference is that 
there is no cat."
