pump capacity / electrical interference
for the pump, I intend to use a thin centrifugal pump with a centeral brushless motor based around a re-wound cd drive stator, but don't know what the power required to move enough water is, especially with small bore pipe (2 X 1/4"
also, when positioning the pump, how far away should it be from the main board to avoid causing interference, as the pump is essentially a large spinning magnet with several amps going to it.
I'm guessing the motor should be as far away as possible, as well as the supply cables.
thanks for the help.
