2. 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

3.  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

4.  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)

5.  Lead used in PCB solder  Use lead free solder in manufacturing process  Some non-RoHS compliant parts  Find RoHS compliant parts for production  PCBs shouldn’t go to the landfill  http://www.webuyics.com/ http://www.webuyics.com/  Acrylic is not incredibly environmentally friendly  Use different material for production  http://www.plasticscrap.us/index.htm http://www.plasticscrap.us/index.htm

6.  Electric Motor  Recyclable!  http://www.usmotorrecycling.com/products.htmlhttp://www.usmotorrecycling.com/products.html  Wooden package  Biodegradable lumber
