Abstract: The sizes of raindrops with radii between 0.025 and 0.2 cm can be measured by amplifying the voltage pulses they make when they hit a high voltage wire. I have made such a device using two wires charged to +2000 V and a differential amplifier. Unwanted radio noise affects each wire in nearly the same way and is thus greatly reduced at the output of the differential amplifier. The device is simple and easy to build, and it works well except in the vicinity of thunderstorm electrical activity.
