A thought just occured to me. Wasn't it you Ian who told me this evening
that dc voltage uses pulse wave modulation to enable a variance in the speed
switch?
If that is true then how does a 12 volt dc car radio's volume control
potentiomenter work? Does it somehow convert the dc to ac for it's volume pot to
work and then
convert it back to dc again? From what you told me earlier about the pwm it
is making me wonder now if my idea to find a 24 volt dc potentiometer would even
work.
Does a dc 24 volt potentiometer even exist or am I missing something? A
little help?
