Other Interesting Programming Projects

  • 1990-1995 Audio mixing and replay control system for a seasonal haunted house attraction in Los Angeles. This included custom hardware that I designed to trigger lights and sound effects within the attraction.
  • 1992 Robot control software written to control a home-made robot. The movements of various robot parts would be set using a graphical user interface. Movement of the robot mouth was automatically generated from sound data.
  • 1992-1994 Timeline based multi-track presentation authoring system allowed for mixed still image and analog video presentations. This was written to author presentations for a high-end presentation system before laptops and MS PowerPoint were capable of high quality slide presentations with transition effects and long before software could play digital video on a home computer.
  • 1991 Closed caption decoder for a stand-alone decoding device. This was written using Z8 assembly and was built before closed caption decoding was available in most television sets.
