Does anyone have ideas (or could point to a person or company) that 
might have a way to safely synthesize an isolated 9VAC for the machines 
from 5VDC?

 From documents like this:


a simple voltage doubler and timer won't completely work.  Would putting 
a 1:1 transformer on the end of the 9V output isolate it?

I was thinking if the isolation issue was handled, creating a more 
pleasing sine wave would be the lesser concern. (maybe a small uC with a 
R2R DAC tied to some power transistors, etc.)
