gary wrote:Harry, I don't have time just now for a full blurb, but I can't see how you are going to use a laser (which may be dangerous anyway) with a nipkow disk as the beam will only be picked up by one or two apertures - if you use a mirror drum that would be different.
FFS can work in daylight too, as long as the lighting is constant (i.e. DC)
TBP CAN be used without sync providing your motor speed is constant - eg a stepper or synchronous motor.
More later...
