@Groundloop,

                 This schematic of Joe Tate's circuit shows your 100% right about the capacitor and diode direction:

Moderator: The circuit drawing was posted to times. I deleted one of them.

Synchro1,

Thank you for posting the Joe Tate's circuit. I now see that my drawing is probably correct.
I now see that my posted circuit is like the Joe Tate's circuit, but is made of several series
steps to get a higher voltage output. I will solder up a prototype board of this circuit tomorrow
and give it a try.

I have designed this circuit in Eagle CAD. Attached is the design files if anybody want to make
a PCB for this. I will solder my first test on a universal printed board first, and if I get some
good result, then I will consider ordering printed circuit boards. A free version of Eagle CAD
can be downloaded from here: http://www.cadsoftusa.com/download-eagle/
