3.  Persistence of Vision  Stroboscopic Effect  Sense  Process  Display  Inspired by LED Cube  Wanted to create aesthetically pleasing apparatus  EE 438 – MOSIS chip Project Background

4. Design Overview Form Factor

5. Design Overview Block Diagram

6.  Constructing the Base/Spinning Platter  MOSIS chip  Microcontroller Programming  LED Array along 3D ring Design Challenges

7.  Chosen Microcontroller  Arduino Nano  2 MOSIS Chips  Power Handling  Dual Power Supplies Important Decisions

8. Risks DescriptionSeverityLikelihood MOSIS IC does not operate as intended.Low Motor does not spin the apparatus fast enough to enable persistence of vision by human eye HighModerate Not being able to deliver enough power to LEDs for desired brightness HighModerate Balance of the LED ringHighLow
