Design and Requirements • IR transmitting Gun • Maximum range of 100ft • IR receiving Vest • Wireless communication with score keeping server • Game server • Wireless communication using Zigbee protocol
Gun and Vest • Gun sends IR data packet • LCD displays game data • Multiple sensors on the vest receive the packet • Packet contains “hit” data • Audio and physical feedback • Hit data is transferred wirelessly to a server

Progress • Ordered IR parts • Began testing IR send/receive • Transmit 15ft at 100 mA • No lens • Added PIC 16F690 to control IR LED • Decide on PIC with multiple USARTs • Got ZigBee Development kit
Challenges • Started with power transistor • Rating not compatible with use • Switched transistor which worked • Long distance communication corrupted • Still receive a signal, but not correct • Will implement Parity Bit • Transmitted only carrier signal • Added PIC16F690 to modulate
Schedule • Over Break • Order LCDs and Processors • Work on server communication • January • Finish IR Communications and Lens Design • Test Basic Server Communication • Finalize data packets • Further • Finish design of gun/vest and test • Finish server program • Test Integrated design
Conclusions • Completed • Ordered Parts • Tested out basic IR send/receive ability • Acquired Zigbee chips • Future Plans • IR individual data packet transfer • Zigbee data transfer • Multiple Sensor differentiation • Battery Design
