Rev-logger

....This unit can measure and remember....
Rev-Logger
the speed during run
26/Mar/2000

This unit can count the revolution of a pinion gear within a certain interval, thus speed of the chassis, record into EEPROM in the chip, and output to display after each run. This unit can record for ca. 20seconds in 0.3s interval. Analysis of obtained data will be interesting because they contains so many information of circuit-run: cornering spped, acceleration, max speed, etc....

X axis is time(sec), Y is velocity (m/s). This data mean brake at 0-3sec, Acceleration till 8sec, full-braking, then slow down. This data indicates the max speed was about 46km/h.(29mph)

Test run at circuit course

I can get very interesting data!! see below!
