WPPSS: Wireless Ping Pong Scoring System
After an early prototype (above) proved somewhat cumbersome in use, this electronic scoreboard was designed. It uses bright 2" LEDS to show the score while the current server is indicated by decimal point. A small infrared transmitter is fitted in each paddle and the score is updated when either player presses a button in the handle. Various sound effects and display patterns serve to annoy the losing player.
Technical details: serial display with 2.3" LEDs from sureelectronics.com. A PIC controller with Vishay IR receiver and piezo buzzer is piggybacked onto the display board and encased in a walnut frame suitable for hanging. The paddle handle is hollowed out to fit a PIC 12F683 controller programmed with a modified SONY SIRC remote protocol, coin battery and an IR LED to transmit wirelessly to the scoreboard.
