For his final year project, Electrical Engineering student Bleddyn Dunn built an automatic scoreboard for his local cricket club. This is a scaled down model of the product.
"I built this to replace the existing scoreboard, which was a very noisy chain-and-pulley system. An external company quoted us £7k which seemed extortionate, so I offered to make it myself. The materials only cost me £260 and it works perfectly, with only one person needed to update the scores."
Bleddyn produced circuit diagrams for the scoreboard system before building it with printed circuit boards (PCBs), which control all of its outputs. Each number on the display turns on every two milliseconds, so the score appears to change simultaneously.
