Development of Strain Gauge based LED Stumps

The Light Emitting Diode (LED) glowing stumps has become more popular in T20 cricket. The stumps light up every time the ball strikes it or a player whips the bails off. These stumps are very costly (around 25 lakhs). This project aims at replacing the conventional LED stumps and bails system with strain gauge - fitted LED stumps, which would make it cheaper. To demonstrate the concept, a strain gauge was mounted on a steel ruler and interfaced with a computer using virtual instrumentation software and a program was generated. The change in strain on impact of the ball was used to light a LED connected to the circuit. The proposed system could be cost efficient and easy to assemble, whilst fulfilling the primary function.
