An ability to: 1. display a pattern with rotating LEDs 2. control the direction in which the pattern is being projected 3. track the angle of arrival of an RF beacon 4. update a projected image while the machine is in operation 5. accept user-generated input to change display
Safety concerns due to the rotating assembly Use protective shield surrounding rotating assembly Place proper warning labels on unit and in manual
Bright light from the LEDs Place warning labels on unit
Potential for POV machine to fall on someone Weighted base to prevent movement Balancing the rotating assembly to lower vibrations Non-skid pads on bottom of unit
Electric shock and thermal burn hazard if a user was to open the box Place warning labels on unit and in manual Insulate conductors with hot glue High ambient temperature testing
RF interference on 1.2 GHz and 2.4 GHz bands 2.4 GHz is unlicensed and we are broadcasting at
very low power (max = 1 W expected ~0.001 W) 1.2 GHz is amateur radio band and we are using
very low power (max = 1 W expected ~ 0.1 W)
