This development also apply to traditional professions, such as carpentry work or service work, but the new aspect is that the work is mediated through online platforms, which seems to affect the working environment for those young workers. Using a standard step/direction stepper driver means you need two control signals per motor, or 96 outputs. Main issue is that very few have any way of detecting the position of the hands, and I need to do that. It has a "Lavet" type stepper motor and two step gear train which reduces the rotation by a factor of 180 whereby a full step driving pulse results in a one degree rotation of the pointer shaft.
