Speedometer for motorcycle

This project was inspired by lack of original instruments on my small motorcycle. First tests were done with measuring PC fan speed (used to measure RPM). Speed measurement is done with hall-effect sensor and permanent magnet on the wheel and fixed time-base to count fly-by of magnet.
Implemented functions: speed, ODO, trip, clock, temperature, rpm (bar), turn lights control with audio signal.
