Abstract:

A mechanical timer has been developed which has a useful range from 0.10 to 100 milliseconds with an error of plus or minus 15.0 microseconds. It has been used successfully in connection with high-speed, multiple exposure photography in applications where electronic timers could not be employed. The device is constructed from standard, easily obtained parts. Author
