3. Problem Statement Background:
The ISU planetarium consists of an optical projection system with a control system that allows for operation and voice recording. Over the years, the original hardware control system began to fail, and the projector became inoperable in 1992.

4. Problem Statement Technical Problem:
The team will complete the design and implement a new control system for the planetarium projector using new hardware and a standard personal computer (PC). The software driven control system must be flexible and should be able to perform recording as well as operating the projector and peripherals.

5. Design Objectives
Design new computer controls for original planetarium projector
Control all lighting of the projector
Control all motor movements of the projector
Create a recognizable interface for projector operators
Operate with low light emissions

6. End-Product Description
Projector shall perform all control functions through new interface
Software, hardware and the projector should be fully tested and debugged
Design shall be easily upgradeable
Installation into the planetarium by semester end

7. Assumptions Both Opto-22 controllers are functional
GUI operates on a Windows 98 based system
Operating environment shall be the ISU planetarium
New system setup will fit in the ISU planetarium

8. Limitations
Restored projector shall maintain all functions of the original projector
GUI shall imitate the original control panel for the benefit of past users
Limited budget
Opto-22 hardware is donated and not easily replaceable

9. Project Risks and Concerns
Loss of critical personnel
Loss of data
Failure of critical equipment
Overspending

10. Technical Approach

19. Closing Summary
The ISU Planetarium Resuscitation project will give physics and astronomy professors the ability to control the entire ISU Planetarium from a PC. This project will save professors’ time and will also make using the planetarium lights and motors easier when performing a show. The technical approach to this problem used by the team allows these goals to be accomplished and leaves room for further development in the future.
