Building an Elapse Timer

Project Description
In this project you can build an Elapse Timer that could be used to measure the speed of maglev vehicles or CO2-powered cars typically found in Technology Education classrooms. The power of this project is that it uses an old computer such as a 286, 386, or 486 and a few parts that should cost less than $5.00.
