<p>A system includes a layer, a shaftless stepper motor, a lighting element, an input magnet, an output magnet, and a pointer. The layer includes first and second opposed sides. The shaftless stepper motor is disposed on the first opposed side of the layer. The lighting element is disposed on the first opposed side of the layer. The input magnet is disposed on the first opposed side of the layer and is connected to the shaftless stepper motor. The output magnet is disposed on the second opposed side of the layer. The pointer is connected to the output magnet. The input magnet connected to the shaftless stepper motor moves, through magnetism, the output magnet and the connected pointer, and the lighting element transmits lights to light the pointer.</p> |
