> I measured around 16 volts DC going into the motor. It was increasing slowly as the motor warmed up.  Started around 15.9 Volts. Does that help?

Sounds like you're in good shape to run it off a DC power supply like in 
the article.  If the popper's own DC power supply is isolated, you could 
just use it.  Note that there's a high chance it isn't isolated.

> It looks like there are two diodes in series attached to each motor terminal.

So..  diode-diode-motor-diode-diode?  Hm.  What's between that and the 
AC power input?  It's not critical, but now you've got me curious...

> Do I need to disassemble it more to learn something else?

Probably not, but now *I* want to disassemble it more!  ha
