A High-Resolution Stopwatch for Cents
Gingl, Z.; Kopasz, K.
Physics Education, v46 n4 p430-432 Jul 2011
A very low-cost, easy-to-make stopwatch is presented to support various experiments in mechanics. The high-resolution stopwatch is based on two photodetectors connected directly to the microphone input of a sound card. Dedicated free open-source software has been developed and made available to download. The efficiency is demonstrated by a free fall experiment. (Contains 4 figures.)
