Measuring Gravity by Free fall

Some of my equipment is very expensive and dedicated to only one job or experiment .Lego EV3 on the other hand can be used with some ingenuity to create many different types of equipment, to record all types of events. Here we are measuring Gravity by free fall and creating this out of Lego can achieve some remarkable results. The time for the drop of 50cm has just over 0.32 of a second giving an estimate of gravity at 9.76 m/s/s. With a bit of programming this is a very decent result and remarkably consistent as well.
