of course... putting a transistor in the motor circut, activated by the switch will make this alot more stable and would quite be my preferred way.
but the man wants something that is extremely low budget and by the looks of his posts, as simple as possible.
the motor would not be a very powerfull one either.
and about the magnets interferring with the motor...
if the motor is situated in the rear of the fan housing and the magnets/switch in the front the problem would not arise... remember we have the benefit of designing the entire system.
i know i'm pissing in a new pool here... but i have tried this with some jurryrigged components and it works alright.
