  3. Introduction • Why we chose this project • Where the project came from • Chris Rockhold’s Patent

  4. Project Overview • Laser "shootout" game • Based on mythical “Old West” gunfights • Two players with weapons and reflective vests face off • Wait for "Draw!" signal and start shooting • First to score a hit within 6 shots wins

  5. Project Overview • Components: • Central Controller • Display Boards (display, RF unit, microcontroller) • Weapons (laser, receiver, microcontroller) • Technologies: • Laser data transmission and optical reception • RF wireless communication • Multi-processor communication

  6. Previous Work • Previous Senior Projects • 1997: Electronic Shootout Game • David Grimm and Scarlet Halabi • Worked only on laser transmission and reception, no software • Receiver functional but unreliable • 1998: Electronic Shootout Game • Nazry Jaafar, Azrin Johari, and Emelia Malek • Receiver was more reliable but worked only at low frequencies • Weapon software functional • Microcontroller communication established

  7. Patents, Standards, and References • Patents • Toy laser guns / light guns • Electronic shootout game (Chris Rockhold’s) • Standards • Laser safety • Electronic toy safety • References • Laser data transmission • Miscellaneous laser applications

  26. Electronic Shootout Patent • Christopher Rockhold, September, 1988 • Abstract:The present invention relates to an electronic shootout game and more specifically to such a game intended to be played by two contestants disposed in facing relation on a prescribed playing field. The game accurately simulates the 19th Century gunfighting practice and is completely controlled by a programmable microprocessor which includes audio and visual display to control and track the progress of the game during play. The guns include a radio frequency transmitter and antenna system which broadcasts the firing and successful hit modes by wireless communication with the computer which provides an instantaneous readout of such game functions.
