Thanks to the Hackaday folks for running this contest. I don't know about y'all, but I have endless uses for pulse width/frequency DC power modulators, and since I have a few nice gate driver ICs lying around for another project…

I just have a few things left to do, but the board can be built from what's posted here.
- Finish numbering the parts and regenerate the silkscreen and parts list. [Done 2006-12-26.]
- Clean up the schematic. [Done 2007-01-10. Click on the image below right.]
- Clean up [done 2006-12-26] and post a more detailed parts list with supplier part numbers [done 2006-12-27] and current prices.
- Move some of the stuff in the manual to separate web pages, clean it all up, and check the links.
- Illustrate the manual better and add some more references.

Though I've dabbled with electricity in various forms off-and-on for thirty years,
this is the first PCB I've tried to make since I was a kid.
(As I dimly recall, those were abject failures, but apparently the bug had bitten!)
I may have put way too much time into this project,
but I figure I'll be able to use the experience for the other more involved project I'm doing.
Hopefully, at least a few people will get something useful out of this,
and perhaps even build a handy-dandy pocket power modulator of their very own.
