This paper presents the design and hardware implementation of a low-power digital event detection system for cricket wicket monitoring using logic gate-based signal processing and discrete switching architecture. The proposed system utilizes a conductive contact interface to transform mechanical bail displacement into a digital electrical signal. An IC 74HC04 CMOS Hex Inverter performs Boolean logic inversion, while a BC547 transistor switching stage controls LED indicators and an active buzzer for real-time audio-visual event indication. The developed hardware employs a rechargeable 3.7 V lithium-ion power source with USB Type-C and photovoltaic-assisted charging. Experimental validation demonstrates reliable operation, reduced circuit complexity and elimination of microcontroller-based processing. The proposed architecture provides a scalable foundation for future FPGA, IoT and advanced embedded system integration.
