Abstract
Beep baseball is a modified version of baseball designed for individuals who are blind or visually impaired. In this game, the baseball emits a continuous beeping sound, when the ball is hit an umpire activates one of two bases, which then emits a buzzing sound. The hitter must locate the base that is buzzing and reach it before a fielder retrieves the ball. Currently the buzzing bases are powered through long physical wires connected to an external power source. These exposed wires create a significant safety hazard for the children who are blindfolded during play.
This project focus is on designing and implementing a wireless base system for beep baseball to improve the safety and accessibility. The new system replaces the wired connections with a wireless communication system consisting of a handheld transmitter for the umpire and two independent receiver units within the bases. When the umpire presses a button, a signal is transmitted to one of the bases, causing it to buzz. Inside each of the bases contains its own internal power supply. A key component of this design is the development of a pulse generator within the base system. The pulse generator operates within each base and works directly with the internal power supply, allowing the base to buzz without external wiring.
Overall, by removing the physical wiring and implementing this new communication devices, this project will enhance the players safety and simplifies the setup of game. This project demonstrates how engineering design can help improve experiences for individuals with disabilities.
