I made a karate timer and a scoreboard. (Where is Akai Electronics going? lol)
We have created a karate timer and score board that can flexibly adapt to rule changes in karate. By using the Raspberry Pi 5 as the "brain," we achieved operation via a numeric keypad, dual screen display (for the operator and for judges/players), and cost reduction. With feedback from federation instructors, we have reached a practical level of completion.
