Comment on A home made PCB stepper motorparentComments−jacquesm4yI'd say that depends more on how much you are willing expend on hardware to drive it. You could slice your coils into tiny segments (essentially: just the tops) and then use the back of the PCB to drive them. They'd be magnetic pixels.
