Jon,

If you're looking for any pointers on robotics, you might want to see if
there's a local hacker space by using this website:
http://hackerspaces.org/wiki/

I discovered these spaces recently when I was trying to get my 3D
printer to work, and the fellows at the local one got me sorted out in a
matter of hours. The spaces are a combination of workshop and
socializing spot for local techies, and you're likely to find both
leading edge knowledge and a very good disposition to pitch in. They
collaborate on projects, and a sub controller I suspect would not fail
to capture their interest.


Thanks,

Alec

I think I found it.  Looks like it was back in 2000 and there is a PDF 
document explaining about PWM dating from 2002.
